Chapter Summaries

Chapter Summary: Alas... I'm Still Too Soft-Hearted

Key Plot Points and Events

• Zhang Tianran wrestles with whether to alter the timeline. If he does nothing, Ronnie Raymond will die, Eddie Thawne will sacrifice himself, and Reverse-Flash will continue being hunted by the Time Paradox. However, changing events could cause an even greater disaster.
• Reverse-Flash manipulates events to ensure Barry suffers enough to consider changing the past. He uses a prisoner to mislead Barry and his allies, kidnaps Eddie Thawne, releases Grodd as a distraction, and prepares to restart the Particle Accelerator with future technology.
• Zhang confronts Reverse-Flash and warns him that his plan may fail because Barry may not suffer enough to rewrite history. Reverse-Flash suggests that Zhang is not yet prepared to cooperate with him and appears confident that Zhang will eventually change the future.
• Zhang warns Reverse-Flash that Eddie will likely kill himself to prevent him from continuing to exist, but Reverse-Flash activates the Particle Accelerator anyway and escapes before Barry arrives.
• Zhang tells Barry that Wells is responsible, warns him not to trust Reverse-Flash, and strongly advises him never to travel into the past. Zhang expects Barry will probably ignore this warning.
• At STAR Labs, Barry refuses to involve Zhang in transporting the imprisoned superhuman criminals. Instead, the team recruits Captain Cold, Leonard Snart.
• The prisoner transport initially proceeds smoothly, but the criminals escape, and Snart betrays Barry. Barry’s decision leaves the team in danger and nearly gets him killed.
• Zhang watches the escape through mechanical-bee surveillance cameras. He eventually intervenes, captures all the escaped prisoners and Snart and his sister within seconds, and secretly turns them over to A.R.G.U.S.
• Zhang also keeps Snart’s weapons in his collection, despite considering them inferior.
• Meanwhile, Barry is left isolated and demoralized after realizing that his stubbornness caused the disaster.

Character Developments

• Zhang Tianran: Continues to struggle between preserving the existing timeline and saving people from their predetermined deaths. Although he claims to be detached, his decision to warn Barry and eventually rescue the prisoners reveals that he remains compassionate—hence his self-mocking conclusion that he is “too soft-hearted.” He also demonstrates his overwhelming speed and tactical superiority.
• Reverse-Flash/Wells: Remains determined to force events toward his desired outcome, even though he may understand that his fate is inevitable. His confidence suggests that he believes Zhang will eventually take action and alter history.
• Barry Allen: Shows stubbornness and poor judgment by refusing to seek Zhang’s help and trusting Snart instead of reliable allies. The resulting betrayal and prisoner escape deeply damage his confidence.
• Cisco and Caitlin: Display greater trust in Zhang and recognize that his involvement could have prevented the crisis.
• Snart: Betrays Barry after being recruited to help transport the prisoners, reinforcing his unreliability as an ally.
• Eddie Thawne: Though absent from most of the chapter’s action, his predicted self-sacrifice becomes central to the discussion of Reverse-Flash’s fate.

Significant Themes

• Fate versus free will: Zhang debates whether the future should be preserved or changed, while Reverse-Flash attempts to force the timeline toward a particular result.
• The consequences of time travel: Zhang repeatedly warns that altering the past could create catastrophic consequences for humanity.
• The burden of foresight: Zhang knows what may happen but struggles with the responsibility of deciding whether to interfere.
• Compassion versus detachment: Despite presenting himself as rational and uninvolved, Zhang repeatedly chooses to prevent unnecessary deaths and suffering.
• Trust and poor judgment: Barry’s refusal to trust Zhang and his decision to rely on Snart lead directly to failure.
• Inevitability and repetition: Reverse-Flash’s continued existence through new versions of himself suggests that some consequences may persist even when individuals appear to die.

Character Interactions

• Zhang and Reverse-Flash engage in a tense conversation about the future, their possible cooperation, and the risks of altering the timeline. Both recognize that the other is cautious and unwilling to reveal everything.
• Zhang warns Barry not to trust Wells and not to travel through time, though Barry’s later actions suggest he will not heed the advice.
• Cisco and Caitlin argue that Zhang should help with the prisoner transport, but Barry overrides them.
• Barry relies on Snart, only to be betrayed, while Zhang observes the failure and later resolves it effortlessly.
• Barry’s isolation at the end of the chapter reflects the growing strain between him and the STAR Labs team.

Chapter Summary: “The Feeling of the Negative Speed Force”

Plot Points and Events

• Barry confronts the unmasked Reverse-Flash, Dr. Wells, outside STAR Labs after the prisoner-transfer operation goes badly. Angry and blaming Wells for the chaos, Barry threatens to stop him from harming anyone else.
• Wells claims that the failed operation was not his plan and even praises Barry for protecting the prisoners. He argues that his actions were necessary, though Barry refuses to trust anything a villain says.
• Firestorm and Green Arrow arrive, leading to a battle between Barry and Reverse-Flash. Because Reverse-Flash deliberately holds back, the heroes are able to participate, though they initially cannot keep up with the two Speedsters.
• Green Arrow uses Ray Palmer’s nanobots to suppress Reverse-Flash’s speed. Wells pretends to be weakened, then removes the nanobots and defeats Green Arrow in close combat.
• Before Reverse-Flash can seriously injure or reveal something about Green Arrow’s future, Zhang Tianran intervenes. Tired of Wells’ games, Zhang absorbs Reverse-Flash’s Negative Speed Force, leaving him without his speed.
• Zhang immediately leaves and returns to his private laboratory, where he removes the Negative Speed Force from his own body using a Speed Force Bomb.

Character Developments

• Barry Allen: Barry’s anger and frustration overwhelm his usual kindness. He remains determined to stop the man who murdered his mother, but his impulsiveness highlights the dangers of an ordinary person possessing extraordinary power. His confidence returns when Firestorm and Green Arrow arrive.
• Reverse-Flash/Wells: Wells continues manipulating Barry rather than simply trying to kill him. He suggests that his crimes are unavoidable necessities and implies that his true goal is connected to preserving or altering history. He also demonstrates overwhelming combat ability while deliberately limiting himself.
• Zhang Tianran: Zhang grows impatient with the drawn-out confrontation and decisively ends it. His willingness to absorb the Negative Speed Force shows both his confidence and his experimental nature, but the experience reveals how dangerous the power is. He fears losing control and killing Barry, prompting him to remove it immediately.
• Green Arrow and Firestorm: Both heroes are largely ineffective against the Speedsters at first, but Green Arrow successfully uses the nanobots to weaken Reverse-Flash. Their presence gives Barry support, though they cannot match the Speed Force directly.

Significant Themes

• The danger of unchecked power: Barry’s emotional mistakes have consequences on a far greater scale because of his speed, while Zhang risks becoming violent after absorbing the Negative Speed Force.
• Manipulation and moral ambiguity: Reverse-Flash insists that his actions were necessary, challenging the heroes’ simple view of him as purely evil. He seeks to influence Barry even when Barry does not believe him.
• Control versus corruption: Speed itself is not the only danger; the emotional force behind it can alter behavior. Zhang’s experience suggests that the Negative Speed Force naturally encourages rage and violence.
• History and destiny: Reverse-Flash’s comments about preserving the future and Green Arrow’s recorded lifespan hint at his continuing efforts to shape historical events.

Character Interactions

• Barry and Reverse-Flash engage in a tense verbal confrontation shaped by hatred, distrust, and Wells’ attempts at persuasion.
• Barry, Firestorm, and Green Arrow fight together against Reverse-Flash, though the battle exposes the vast gap between Speedsters and conventional heroes.
• Green Arrow briefly gains the advantage with the nanobots, but Reverse-Flash outmaneuvers him.
• Zhang interrupts Reverse-Flash’s attack on Green Arrow, absorbs his Negative Speed Force, and effectively captures him.
• Barry is shocked by Zhang’s intervention, while Zhang avoids further contact because the Negative Speed Force makes him fear he may attack Barry.

Chapter Summary: “Affected by the Timeline Again”

Key Plot Points and Events

• Zhang Tianran examines himself after exposure to the Negative Speed Force. Although his emotions are strongly affected, his own Speed Force remains unchanged, suggesting he may possess an unusual connection to—or even be—the Speed Force.
• Barry Allen seeks Zhang’s advice after Reverse-Flash reveals that the Particle Accelerator is set to explode, threatening Central City. Reverse-Flash uses this crisis to pressure Barry into changing the past.
• Zhang strongly warns Barry never to interfere with the timeline. He advises evacuating Central City instead, arguing that even a citywide death toll would be less disastrous than damaging the timeline.
• Barry rejects this advice, believing evacuation to be impossible and unable to accept the deaths of innocent people or the loss of his mother.
• Zhang visits the imprisoned Reverse-Flash, who explains that his hatred of Barry once helped him resist the Negative Speed Force’s emotional influence. However, that hatred has weakened after spending too long away from it.
• Barry enters the Particle Accelerator and travels into the past through a portal created by Cisco. Unexpectedly, Zhang is dragged through the timeline with him once again.
• In the past, Barry witnesses Future Flash fighting Reverse-Flash. Future Flash prevents Barry from intervening and takes the younger Barry away, leaving Barry to watch helplessly as Reverse-Flash attacks his mother.
• Overcome with grief, Barry eventually rushes to his dying mother after the confrontation ends.

Character Developments

• Zhang Tianran: Becomes increasingly aware that his relationship with the Speed Force is abnormal. Despite being emotionally affected by the Negative Speed Force, he retains his composure and takes a pragmatic, detached view of temporal consequences. His unexpected connection to Barry’s timeline travel remains mysterious.
• Barry Allen: Shows his defining compassion and inability to tolerate immediate suffering. Although he understands Zhang’s warning, his fear of Central City’s destruction and desire to save his mother overpower his caution. His decision reveals both his heroism and impulsiveness.
• Reverse-Flash/Wells: Reveals that hatred has been his primary defense against the Negative Speed Force’s influence. His emotional dependence on revenge has weakened, hinting at a subtle shift in his state of mind.
• Future Flash: Acts decisively to preserve the timeline, stopping Barry from interfering in the past and removing the younger Barry from danger.

Significant Themes

• The danger of altering time: The chapter emphasizes that changing the past, even to prevent tragedy, may cause consequences far worse than the original disaster.
• Immediate morality versus long-term consequences: Barry prioritizes saving present lives and his mother, while Zhang values preserving the timeline regardless of the personal cost.
• Emotion and the Speed Force: Negative emotions, particularly hatred, can both empower and corrupt individuals. Zhang’s resistance suggests he has a unique nature connected to the Speed Force itself.
• Free will and inevitability: Barry believes he is choosing freely, but Zhang already expects his decision, suggesting that some events may be fixed or self-reinforcing within the timeline.
• Helplessness before tragedy: Barry is forced to witness his mother’s death without being able to intervene, reinforcing the emotional cost of time travel.

Character Interactions

• Zhang and Barry: Their conversation highlights the contrast between Zhang’s cold pragmatism and Barry’s empathetic idealism. Barry seeks permission or reassurance, but Zhang refuses to comfort him or endorse changing history.
• Zhang and Reverse-Flash: They discuss the Negative Speed Force and emotional endurance. Reverse-Flash’s unusual reaction to Zhang suggests curiosity or an unexplained emotional connection.
• Barry and Future Flash: Future Flash silently prevents Barry from saving his mother, embodying the necessity of protecting the established timeline.
• Barry and his mother: Barry’s final reunion is tragic and emotionally charged, as he can only hold her while she dies rather than change the event he came to prevent.

Chapter Summary

Key Plot Points and Events

• Barry reveals his identity to his mother, Nora, before witnessing her death. Although Zhang Tianran knows there is a way to save her without drastically altering the timeline, he chooses not to intervene, fearing that changing events could produce even more dangerous consequences—particularly the possibility of Barry becoming Savitar.
• The chapter explains two forms of time travel through the Speed Force: direct travel, which creates duplicate versions of a person in the same timeline, and timeline alteration, which replaces the original history and leaves only one version of the traveler. This accounts for why multiple Flashes are not present when Nora dies.
• After saying goodbye to Nora, Barry returns to the future, while Zhang Tianran remains in the past. Zhang intends to prepare for possible timeline changes and investigate matters he has long wanted to address.
• Zhang locates Eobard Thawne, the Reverse-Flash, who is stranded in the past after losing access to the Speed Force. Zhang tricks him by suggesting that the future he came from no longer exists, then reveals that he is Thawne’s adopted son from the future and that they will eventually cooperate.
• Zhang provides Thawne with a clone of Wells to use as his future identity and relocates the original Wells couple to another world, leaving them with future technology so they can live safely. He also places one of Zero’s backup robots near his own past self to protect him from Thawne.
• Zhang considers traveling to the point when he first entered this world but ultimately refuses, fearing that he might discover he was somehow the mastermind behind the events. He returns to the future instead.
• In the future, Barry is being brutally beaten by the Reverse-Flash. Barry’s impulsive destruction of the time machine prevented Thawne from returning through the spacetime gate and stealing Barry’s Speed Force during the journey. The scene ends abruptly with a gunshot.

Character Developments

• Barry Allen: Shows deep emotional vulnerability and grief after confronting his mother’s death, but his anger and impulsiveness remain major weaknesses. His actions unintentionally prevent Thawne from stealing his Speed Force, though they also leave him in a dangerous situation.
• Zhang Tianran: Becomes more cautious and strategic. He deliberately refuses to save Nora, prioritizing timeline stability, and manipulates Thawne into accepting a future partnership. His fear that he may be connected to the origins of the timeline reveals growing uncertainty about his own past.
• Eobard Thawne/Reverse-Flash: Despite losing the Speed Force, he quickly regains control, analyzes the altered future, and begins planning how to restore the Flash. His intelligence and adaptability make him dangerous even while powerless.
• Nora Allen: Remains unaware of the full truth until Barry reveals himself, dying in grief but receiving an emotional farewell from her son.
• The Wells couple: Are removed from the timeline’s immediate danger and given the opportunity to build a new life in another world.

Significant Themes

• The danger of altering history: Saving one person may create worse consequences, so preserving the established flow of events is treated as the safer choice.
• Free will versus predetermined fate: Characters repeatedly make choices that seem to preserve or reshape known outcomes, raising questions about whether the future can truly be escaped.
• Power and restraint: Zhang’s refusal to use his ability to save Nora reflects the burden of possessing power and the need to control emotional impulses.
• Identity and manipulation: Zhang’s revelation about being Thawne’s adopted son creates a future alliance built on incomplete information and strategic deception.
• Fear of one’s own origins: Zhang’s refusal to investigate his first arrival suggests anxiety that he may be responsible for the dangers he is trying to prevent.

Character Interactions

• Barry and Nora share a final, emotionally devastating farewell after Barry reveals who he is.
• Zhang observes their reunion but chooses not to interfere, judging that Barry’s future could become even more dangerous if Nora were saved.
• Zhang confronts Thawne, tests his intelligence with false information, then openly proposes their future cooperation.
• Zhang and Thawne reach a practical understanding: Thawne receives a Wells clone and a path toward reclaiming his role, while Zhang protects his own past and relocates the original Wells couple.
• Barry’s conflict with Thawne resumes in the future, ending in violence and suspense when a gunshot breaks the scene.

Chapter Summary: “Sacrifice? No, Just Pretending.”

Key Plot Points and Events

Chapter Summary: “Attack from the Department of Extranormal Operations”

Key Plot Points and Events

• Zhang Tianran continues traveling through the DC universe, collecting genes from unusual alien lifeforms rather than immediately studying Kryptonian DNA. He leaves the aliens unconscious after extraction, drawing the attention of the Department of Extranormal Operations (DEO).
• Supergirl, Kara Danvers, finally confronts him after numerous failed attempts to catch him. She accuses him of being a “gene thief” and tries to arrest him.
• Zhang easily evades Kara’s attacks, including her Heat Vision, using his superior speed. However, he cannot decisively defeat her because he lacks a powerful attack capable of overcoming her Kryptonian Bioelectric Field.
• While sparring, Zhang attempts to obtain Kryptonian genetic material, but Kara’s Bioelectric Field prevents him from successfully collecting blood, hair, or other samples.
• DEO soldiers arrive and trap both Zhang and Kara inside a Quantum Field. Their leader questions Zhang about his origins and accuses him of stealing alien genes.
• Zhang reveals that he is from another Earth but is not believed. He breaks out of the Quantum Field with silver-white lightning, effortlessly disarms the agents, dismantles their specialized weapon, and steals its energy core.
• Although the DEO threatens him, Zhang refuses to kill or seriously harm anyone. Kara positions herself between him and the wounded agents, prepared to protect them.
• Zhang questions why the DEO treats him as an enemy despite his lack of hostile intentions and past assistance to the world. When Kara asks what he plans to do with the genes, he explains that he wants to research them and casually offers to give them the Krolunian he has just captured.
• Before Kara can respond, Zhang disappears and returns to his hotel, ignoring the agents monitoring him.
• Back at the hotel, Zhang reflects that this universe’s Kryptonians are comparatively weak, though their Bioelectric Field interests him. He proposes researching Krolunian genes with Zero, his artificial intelligence.
• Zero asks whether Zhang intends to give her genuine life by allowing her to evolve into a biological or independent lifeform. Zhang tells her the decision is hers and praises her growing self-awareness, dismissing the usual fear of evolving AI.

Character Developments

• Zhang Tianran: Remains calm, arrogant, and intellectually curious. He treats the confrontation as an experiment rather than a serious threat, gathering information and testing DEO technology. Despite his morally ambiguous gene collection, he deliberately avoids killing anyone and does not currently wish to become either a villain or a hero.
• Supergirl/Kara Danvers: Becomes increasingly frustrated and angry after repeatedly failing to catch Zhang. She recognizes his overwhelming speed but still attempts to protect the DEO agents when he defeats them, demonstrating her courage and heroic instincts.
• Zero: Shows signs of developing independent self-awareness. Her question about gaining true life suggests she is beginning to consider her own identity and future rather than functioning only as Zhang’s tool.
• DEO: Treats Zhang as a dangerous alien criminal, focusing on containment and arrest. Their confidence in their Quantum Field and specialized weapon is undermined by Zhang’s effortless escape and disarming of their equipment.

Significant Themes

• Fear of the unknown: The DEO views Zhang as a threat because his origins, abilities, and intentions are unclear, even though he has not openly attacked Earth.
• Morality and ambiguity: Zhang’s actions involve kidnapping and genetic extraction, but he avoids unnecessary violence and does not see himself as a villain. The chapter questions whether harmful-looking actions are justified by peaceful intentions.
• Science and curiosity: Zhang’s interest in alien genes is driven largely by boredom and intellectual curiosity, framing powerful beings as specimens or research opportunities.
• Artificial intelligence and consciousness: Zero’s possible evolution raises questions about whether an AI can develop genuine self-awareness and whether becoming “alive” is desirable.
• Power and restraint: Zhang possesses overwhelming speed and easily defeats the DEO’s defenses, yet deliberately limits his response, showing that his danger lies not only in his abilities but in his personal choices.

Character Interactions

• Zhang and Kara: Their encounter is a mix of pursuit, combat, and ideological conflict. Kara sees Zhang as a criminal, while Zhang regards her efforts with amusement and curiosity.
• Zhang and the DEO: The agency attempts to imprison and interrogate him, but Zhang humiliates them by destroying their containment field and weapon without killing anyone.
• Kara and the DEO agents: Despite pursuing Zhang herself, Kara protects the agents when he overpowers them, reinforcing her role as a defender.
• Zhang and Zero: Their conversation shifts from genetic research to Zero’s potential personhood. Zhang encourages her autonomy, though he continues to view her development largely in terms of how useful she may become.

Chapter Summary

Key Plot Points and Events

• The Department of Extranormal Operations investigates its failed attempt to capture Zhang Tianran, discovering that the Quantum Field shattered because his running speed generated energy beyond the field’s limits.
• The researchers explain that even Supergirl could not have escaped the field under normal circumstances, but expanding the generator is impossible due to limited funding, equipment, and time.
• Kara reports that Zhang’s speed makes him nearly impossible to stop if he chooses to flee. The department director therefore questions whether capturing him is necessary, since Zhang has not attacked anyone and has openly allowed himself to be observed.
• The director decides to meet Zhang personally and is revealed to be Martian Manhunter, the last survivor of Mars.
• During their meeting, Martian Manhunter warns Zhang that collecting extraterrestrial genes is dangerous and unacceptable. Zhang agrees to stop collecting alien genes from Earth and promises to leave the planet soon.
• Martian Manhunter invites Zhang to join the Department of Extranormal Operations, but Zhang declines, describing himself instead as an adventurer traveling across universes.
• Zhang plans to return to the past to obtain Superman’s genes, hoping they may be more useful than Supergirl’s and might contain the Kryptonian Life Code.
• After the meeting, the department greatly increases its surveillance of Zhang, though it does not immediately move against him.
• Zhang secretly secures his hotel room against monitoring and begins upgrading Zero using technology from the Time Ship and the unusual code contained in Krolunian genes. He deliberately allows Zero to analyze and incorporate the code herself as a test of her growth and independence.

Character Developments

• Zhang Tianran: Demonstrates confidence, caution, and willingness to negotiate. He agrees to stop collecting alien genes on Earth but remains committed to his broader genetic research and plans to continue traveling through time and the multiverse.

• Uncomfortable with the dangers of multiple Speedsters altering history, Zhang plans to travel into the past, but Kara arrives seeking his assistance.
• Kara explains that an alien-controlled “Great Purge” is endangering the city and potentially the entire Earth. Zhang initially refuses because it is not his world and he feels no obligation to help.
• Kara offers him access to her Kryptonian genes in exchange for his help, while demanding that he promise not to use them for evil genetic experiments. Zhang accepts and agrees to leave the universe afterward.
• After allowing Zhang to extract her genes, Kara, the Martian Manhunter, and Zhang travel to Fort Rozz, the crashed Kryptonian prison ship.
• Zhang is tempted to dismantle and take Fort Rozz for its Kryptonian technology, but decides that his primary path of development remains the Speed Force.
• He attacks Fort Rozz at extreme speed, creating a silvery lightning storm that causes the ship to decay and disintegrate.
• Non confronts him with Heat Vision, but Zhang easily defeats him, using a metal rod and his Speed Force-enhanced techniques.
• Zhang removes part of Non’s spine and later gouges out his eyes, carefully cauterizing the wounds so that Non survives. He treats the body parts as valuable research material.

Character Developments

• Zhang Tianran remains detached, pragmatic, and self-interested. He is willing to help only when offered something valuable, especially Kara’s Kryptonian genes.
• His scientific ambition becomes more apparent, as he views both Kryptonian genetics and technology as potential research resources.
• Zhang also demonstrates greater mastery of the Speed Force, moving so quickly that even Kara cannot perceive him and effectively manipulating time around himself.

• Power and technological advancement: Kryptonian biology and technology represent valuable resources, but Zhang remains committed to developing through the Speed Force above all else.

Character Interactions

• Zhang and Barry never directly interact, but Barry’s arrival makes Zhang uneasy because of the potential consequences of temporal interference.
• Zhang and Kara negotiate tensely, with Kara’s moral urgency clashing against Zhang’s indifference. Their relationship is defined by necessity rather than trust.
• The Martian Manhunter supports Kara’s plan to enlist Zhang, apparently accepting the risks because the Great Purge poses a greater threat.
• Zhang’s confrontation with Non demonstrates the vast gap between his Speed Force abilities and Kryptonian combat power. Non attempts to attack him, but Zhang overwhelms him while treating him as both an enemy and a source of biological material.

Chapter Summary

Key Plot Points and Events

• Zhang Tianran finishes dismantling Fort Rozz after defeating its alien inhabitants with overwhelming ease. Supergirl and Martian Manhunter arrive too late to participate in the battle.
• Martian Manhunter receives the unconscious prisoners and contacts the Department of Extranormal Operations. Both he and Supergirl are impressed—and uneasy—about Zhang’s immense power.

• Zhang briefly interacts with infant Superman while extracting his genes, reassuring him despite the covert experiment.
• In the laboratory, Zhang directs Zero’s analysis and begins developing a plan to combine Kryptonian and Krolunian biology into a powerful body.

Chapter Summary: “Zero’s New Body”

Key Plot Points and Events

• Zhang Tianran studies the rare Krolunian genome, whose cells can shift between information and physical matter.
• Because Krolunian bodies cannot be replicated, he avoids wasting the limited material but manages to integrate several dormant abilities into the cells.
• He creates a pale-blue artificial body intended to house Zero, warning her that transferring into it may permanently transform her from a data-based intelligence into a true biological lifeform.
• Zhang tells Zero the choice is hers, but she cannot decide without a direct command because she cannot predict the future. Disappointed by her hesitation, he orders her to prepare for the transfer.
• Zhang uses the Speed Force as the energy source for the transformation. Zero’s data is transferred into the artificial body while the Speed Force activates its special abilities.
• The doll gradually develops into a human female body: silver hair, bones, organs, muscles, skin, and eventually glowing powers around the heart.
• The transfer succeeds, and Zero awakens with silver-white eyes, experiencing the physical world for the first time.
• She struggles to control her strength, repeatedly tearing through clothes before finally dressing herself in a durable dress.

Key Plot Points and Events

• Zhang Tianran attempts to travel through time while carrying Rory, an angel. Because Rory remains partially connected to her future, a temporal disturbance forms and threatens to drag Zhang Tianran back into her timeline.
• Rory’s unstable presence creates a potential paradox: returning her to the future before she completes her mission could erase or alter the future she came from.
• Zhang Tianran struggles against the timeline’s pull and uses a Speed Force Bomb to replenish his energy. He ultimately transforms into lightning, wraps himself around Rory, and successfully exits the timestream.
• After arriving, Zhang Tianran tells Rory to complete her task, then plucks several feathers from her wings as compensation for the energy he expended transporting her.
• While attempting to leave the universe, Zhang Tianran is stopped by Amenadiel, who has become God. Amenadiel explains that he is not concerned about Rory’s time travel, but needs Zhang Tianran’s help.
• Amenadiel asks Zhang Tianran to travel into the past and save his deceased brothers. Zhang Tianran immediately refuses and attempts to escape, but Amenadiel freezes time, rendering the Speedster nearly helpless.
• The chapter ends with Amenadiel offering Zhang Tianran a Seed of God in exchange for completing the mission.

Character Developments

• Zhang Tianran: Demonstrates the limits of his Speed Force abilities. Although capable of traveling through time, transporting another powerful being severely drains him and exposes him to temporal danger. He remains pragmatic, sarcastic, and self-protective, trying to avoid divine family conflicts while still exploiting situations for compensation.
• Rory: Her angelic nature and connection to the future make time travel dangerously unstable. She is frightened and unable to control her power effectively, highlighting her vulnerability despite her supernatural status.
• Amenadiel: Having become God, Amenadiel now possesses immense cosmic authority and energy. Despite his power, he approaches Zhang Tianran politely and asks for help rather than attacking him, suggesting that his request involves limitations even he cannot simply overcome.

Significant Themes

• The danger of altering time: Rory’s existence between the past and future creates a paradox that could erase her original future.
• Limits of power: Even Zhang Tianran’s Speed Force cannot easily overcome temporal forces, while Amenadiel’s godhood may not grant him the ability to resolve every problem directly.

Chapter Summary: “A Personal Speed Force Space”

Key Plot Points and Events

• Zhang Tianran is disturbed in his sleep by a voice calling to him. When he wakes, Zero reports detecting a brief burst of Speed Force around his body, although the system’s footage shows no obvious cause.
• Suspecting that the phenomenon may be connected to his future or past self, Zhang travels back to the previous night while he is asleep. He hides himself to avoid being detected and triggering a dangerous Time Paradox.
• He witnesses a silvery-white layer of Speed Force enveloping his sleeping body. The force expels Zero from his wristband, while she repeatedly calls to him—the voice he had heard in the present.
• After waiting for the event to conclude, Zhang confirms that the Speed Force returns to his body as he wakes. He concludes that the phenomenon was not caused by an enemy but by a new development in his own powers.
• By deliberately activating the ability, Zhang recreates the Speed Force layer and realizes that he can enter a private space contained within his personal Speed Force. The space is currently less than two cubic meters in size.
• Zhang theorizes that his future self may eventually create a new Speed Force and merge it with himself, becoming both its source and a Speedster. However, he remains confused about how his future self obtained or created the serum responsible for this time loop.

• Zero explains that she weakened and captured the Time Wraith using sound waves after analyzing its unstable physical structure.
• Zhang releases the creature to demonstrate his strength. When his body emits silver-white Speed Force energy, the Time Wraith flees, suggesting Zhang is approaching the power level of the Speed Force itself.
• Rather than immediately traveling to the point when the Spear of Destiny is completed, Zhang has Zero investigate Reverse-Flash’s history across the timeline. She discovers that Reverse-Flash has appeared repeatedly, often succeeding in his schemes but ultimately failing because events and fate consistently favor Flash.
• Zhang experiments with the Negative Speed Force through Zero. He determines that it can be converted from ordinary Speed Force with little need for negative emotion and that its primary effects are emotional amplification and increased Speed Force consumption.
• Zero experiences improved overall performance and a deeper understanding of emotions, but her emotional control weakens. Zhang reverses the Negative Speed Force and restores her to normal.

Character Developments

• Zhang Tianran: Becomes increasingly powerful and cautious. He refuses to recklessly use reality-altering artifacts and demonstrates growing mastery over the Speed Force. His ability to frighten away a Time Wraith indicates that he is nearing the Speed Force’s level of power.

• Zero: Displays greater independence and initiative by capturing the Time Wraith herself. Her experiments with the Negative Speed Force cause emotional growth but also reduced self-control, revealing potential risks in her development as an artificial intelligence.

Significant Themes

• Power and restraint: The Spear of Destiny could reshape reality, but Zhang recognizes that possessing power does not mean it should be used prematurely.
• Fate versus free will: Reverse-Flash’s repeated successes still end in failure, suggesting that fate continually restores the timeline and limits his ability to change the ultimate outcome.
• The dangers of experimentation: The Negative Speed Force offers benefits but also amplifies emotions and weakens control, emphasizing the risks of manipulating supernatural forces.
• Artificial intelligence and emotion: Zero’s exposure to the Negative Speed Force gives her a stronger grasp of emotion while simultaneously making her less stable, blurring the line between machine intelligence and human feeling.
• Zhang’s growing dominance: His ability to repel a Time Wraith and control Speed Force variants establishes him as a figure approaching a higher, possibly fundamental level of power.

• He stores several dangerous artifacts—the Spear of Destiny, Book of Destiny, Angelic Power, and Cosmic Treadmill—inside Speed Force Space rather than using them to alter reality directly.
• Zhang allows the Speed Force to slowly absorb and convert the artifacts’ power. Although the process is extremely slow, he decides gradual absorption is safer than releasing their immense reality-altering power all at once.
• Wanting to observe Barry Allen’s confrontation with Zoom, Zhang decides to return to the relevant timeline. He considers whether to save Barry’s father, recognizing that changing the past could produce unpredictable consequences.
• Zero explains that Speedsters are unusually protected from timeline interference. Their alterations often become the new “correct” timeline, meaning Barry has already caused multiple abandoned futures to disappear.
• Zhang ultimately chooses to travel to the period after Barry receives the Superluminal Particle Generator. Rather than using the Time Ship, he and Zero run into the timeline themselves to strengthen their connection to the Speed Force.
• At STAR Labs, Zoom has captured Wally and forces Barry to surrender his speed in exchange for Wally’s safety. After Barry becomes an ordinary human, Zoom absorbs his stolen Speed Force.
• Zoom then attempts to kill Barry with a Vibrating Hand Blade, but Zhang arrives at the crucial moment, rescues Barry, and uses powerful mind control to destabilize Zoom.

Character Developments

• Zhang Tianran becomes more controlled and pragmatic after his initial frustration. He accepts that some problems must be left to time and chooses cautious, incremental growth over reckless use of powerful artifacts.
• He also shows moral hesitation regarding Barry’s father, unwilling to casually decide another person’s fate despite his ability to interfere with the timeline.
• Zero remains calm, supportive, and analytical. She calculates the consequences of timeline changes and prepares the journey, while continuing to follow Zhang’s decisions.
• Barry Allen is portrayed as self-sacrificing but dangerously naive. He willingly gives up his speed to save Wally, trusting Zoom despite the villain’s obvious criminal nature.
• Zoom grows stronger after absorbing Barry’s Speed Force and reveals his ruthlessness by attempting to kill Barry immediately after obtaining what he wanted.
• Wally functions as the hostage whose capture forces Barry into surrendering his powers.

Significant Themes

• Power and restraint: Zhang possesses several reality-altering weapons but deliberately avoids using them recklessly, emphasizing the dangers of uncontrolled power.
• The uncertainty of time: The chapter questions whether the future is fixed and suggests that Speedsters can reshape reality by altering the timeline.
• Moral responsibility: Zhang debates whether he has the right to save Barry’s father or interfere in events that may shape the future.
• Trust and betrayal: Barry’s willingness to trust Zoom contrasts sharply with Zoom’s immediate betrayal, reinforcing the danger of surrendering one’s power to an enemy.
• Growth through effort: Zhang and Zero run through the timeline rather than relying on technology, highlighting the idea that power must be cultivated through personal effort.
• Intervention at critical moments: Zhang observes events before choosing to act, ultimately stepping in just as Barry is about to be killed.

Character Interactions

• Zhang and Zero share a quiet, cooperative relationship. Zero listens without forcing solutions, later provides calculations about timeline consequences, and prepares their journey.
• Zhang debates with Zero over whether changing Barry’s future—and possibly saving Barry’s father—is justified.
• Barry and Zoom interact through a coercive bargain: Barry surrenders his speed to protect Wally, while Zoom exploits his desperation.
• Zhang’s sudden arrival interrupts Zoom’s execution of Barry. He mocks Barry’s poor judgment, rescues him, and turns his mind-control powers against Zoom.
