Hu Yu expanded the fleet using Two-Dimensional Energy and mechanical bodies while the academicians searched unsuccessfully for a way to destroy black holes. With no viable weapon found, he considered using the base’s unusual flow of time to build fleets for humanity.

• The fleet learned that more than ten thousand square meters of stored Two-Dimensional Energy could trigger dimensional reduction, so it sealed the energy in discs designed to merge it at designated locations.
• Hu Yu expanded the fleet while the academicians tested ways to destroy black holes and concluded that their available methods could not overcome them.
• Hu Yu asked Zu about destroying black holes, but Zu had no solution, so the academicians abandoned weapon-based approaches.
• Hu Yu replicated mechanical bodies and produced Conquerors on an assembly line, relying on human control and Zu’s supervision to prevent rebellion.
• Hu Yu considered building fleets at the base, where its flow of time could allow humanity to produce trillions of ships in only a few decades by the vast universe’s time.

After more than 60,000 years in the Mirror Sub-Universe, humanity built a vast fleet and Hu Yu used Zu’s offer to send the Conquerors back into the three-dimensional universe. The Conquerors destroyed the Fish Horse Star Civilization’s fifty billion warships, and Hu Yu escaped with the fleet into the fourth dimension.

• Hu Yu and Academician Zeng discussed how to deceive Zu into returning humanity’s civilians, and Hu Yu said he had a plan that would not endanger them.
• Hu Yu told Zu that humanity had a way to destroy the black holes, and Zu sent the two-dimensionalized Conquerors through the exit to test it.
• The emerging Conquerors attacked the Fish Horse Star fleet with Two-Dimensional Energy and destroyed all fifty billion warships.
• The Fish Horse Star Civilization’s First Leader ordered the fleet to reinforce its defenses and expected the humans to reveal their location.
• Hu Yu, Gao Jianchuan, Chen Peng, and several academicians entered the fourth dimension and used gravitational waves to direct the hidden fleet.

Hu Yu’s fleet reached a giant black hole and increased the density of the surrounding space to weaken its influence, temporarily cutting off its connection to other spaces. After ordering the fleet to return to the Mirror Sub-Universe, Hu Yu stayed behind to seek a powerful force for dealing with the Fish Horse Star Civilization.

• News spread that humanity had destroyed the Fish Horse Star Civilization’s warships, raising hopes among the Star Ring Alliance civilizations.
• A shadow near the Conqueror Fleet suspected that the Mirror Sub-Universe contained matter and energy and realized that it existed.
• Hu Yu’s fleet arrived at a giant black hole and entered its accretion disk to study how to hide it from Zu.
• At Academician Zeng’s suggestion, eight trillion Conquerors drew energy from the fourth dimension to increase spatial density around the black hole and weaken its influence for about five hundred years.
• Hu Yu sent Jianchuan and the academicians back to the passage and said he would seek a powerful force to help deal with the Fish Horse Star Civilization.

Hu Yu returned to Alliance Space and urged its member civilizations to unite against the Fish Horse Star Civilization after revealing it originated outside the Milky Way and threatened the central black hole. The alliance agreed to prepare for war while Hu Yu’s humans sought a way to build fleets deeper inside the Mirror Sub-Universe.

• Hu Yu found that Alliance Space had moved, then followed Tian Feng through a hidden passage to reach it.
• Hu Yu thanked the allied civilizations and announced his intention to destroy the Fish Horse Star Civilization, despite concerns about the risks of all-out war.
• Hu Yu revealed that the Fish Horse Star Civilization came from outside the Milky Way and might be trying to destroy the central black hole, prompting the alliance leaders to support war.
• Hu Yu proposed moving into the Mirror Sub-Universe to build fleets with a time advantage, and the alliance explained that its technology could not travel through the spatial fragments.
• Hu Yu said humanity would create a passage deeper into the Mirror Sub-Universe and insisted that the Fish Horse Star Civilization’s leader must stand trial before humanity.
• The allied civilizations agreed to reinforce the central black hole’s defenses while Hu Yu’s humans worked on the passage.

Hu Yu rallied the Star Ring Alliance civilizations and prepared them to face the Fish Horse Star Civilization, then returned to the Mirror Sub-Universe to find Zu missing. He continued deeper inside while concealing his suspicions and investigating why the rescued people seemed to have experienced no time apart from the fleet.

• Hu Yu left Alliance Space and told Gao Jianchuan that he would unite the Star Ring Alliance, share technology, and develop its civilizations to fight the Fish Horse Star Civilization.
• Hu Yu found the Carina Civilization, shared fourth-dimensional navigation technology, and instructed its leader to follow his plan.
• Hu Yu found the Zhalong Star Civilization, Brilliant Star Civilization, North Star Civilization, South Star Civilization, Sand Star Civilization, Quaking Star Civilization, Crystal Civilization, and Great Cang Civilization, learned they had been attacked, and told them to leave the defensive line.
• Hu Yu escorted the Carina Civilization to a hiding place, recovered the bases left in two-dimensional space, and reunited with Chen Peng and the returning Xuan Star Civilization fleet before entering the Mirror Sub-Universe.
• Hu Yu found his fleet and people inside the Mirror Sub-Universe, but Zu was missing, so he concealed his concern and led the fleet onward.
• Hu Yu noticed that the people Zu had taken away behaved as if they had not been separated from the fleet for more than sixty thousand years.

Hu Yu led the fleet through the space fragments and found a mined celestial body, which suggested that a powerful Galactic-Level Civilization had entered the Mirror Sub-Universe. He gathered the academicians to devise a stable passage through the void-filled fragments, and Academician Zeng proposed that they first find a way to fill or bypass the void.

• Hu Yu guided the fleet through the fragments until it reached an enormous fragment containing a Jupiter-sized celestial body's remains and active human robots.
• Hu Yu realized that Zu's arrangements had concealed evidence of a powerful civilization, and feared the unseen Galactic-Level Civilization.
• Hu Yu convened the academicians to discuss building a stable spatial passage so fleets could travel through the Mirror Sub-Universe and support future wars.
• Academician Zeng explained that the void drained fleet energy and could tear apart ships, especially those from Small Star Sector Civilizations.
• Academician Zeng described his theory that the void was anti-space created by spatial distortion and said the passage would require another method than repairing space directly.

Hu Yu’s fleet began building a massive Fourth Reversed State pipeline to defend against the Fish Horse Star Civilization while they waited for reinforcements. Ten years later, Wen Zhonghua delivered Zu’s message warning that a hidden enemy from the galaxy threatened both Zu and humanity, leaving Hu Yu determined to strengthen the fleet and investigate the increasingly wary Great Star Region Civilizations.

• Hu Yu chose to build a thousand-light-year Fourth Reversed State pipeline so the fleet could travel through the Mirror Universe while protected from the Void.
• Hu Yu waited for the five Great Star Region Civilizations to arrive with Alliance Space, since the Fish Horse Star Civilization could attack through the fourth dimension and the fleet could not yet face it alone.
• A J-90 fighter raced toward the Milky Way at ten thousand times the speed of light.
• Ten years later, Wen Zhonghua summoned Hu Yu to a shielded room and gave him a storage device containing a message from Zu.
• Zu warned Hu Yu that a powerful enemy from the galaxy—not the Fish Horse Star Civilization—was coming, and urged humanity to develop by any means necessary; he also provided coordinates where Hu Yu could find him.
• Hu Yu and Wen Zhonghua discussed their suspicions about the Great Star Region Civilizations, then agreed to strengthen the fleet while Hu Yu handled the civilizations and Wen Zhonghua managed affairs at home.

Hu Yu received a message from Yan Xue revealing that the Snow Tribe was in trouble in Sextans, and he decided to lead an expedition to rescue them. He concealed the Snow Tribe’s identity from the Star Ring Alliance and the great star region civilizations, claiming he was going to aid other humans.

• Hu Yu and Wen Zhonghua recovered a modified J-90 carrying a message from Yan Xue, who returned the fighter and shared technology before asking Hu Yu to say goodbye.
• Academician Xiao and Academician Zeng concluded that Yan Xue had gone to Sextans to seek a way to protect the Snow Tribe.
• Hu Yu ordered the Conquerors to assemble for an expedition to Sextans.
• Hu Yu told the other civilizations that humans in Sextans needed rescuing, hiding his real purpose to keep them from coveting the Snow Tribe’s technology.
• Leader Yun San asked Hu Yu whether he was going to Sextans, and Hu Yu confirmed that his people there might be in trouble.

Hu Yu led a vast fleet toward Sextans to rescue Yan Xue, who had been trapped by the region’s civilizations. Yan Xue’s fleet held off the attackers, but its energy was running low, and he refused to abandon the remains of his ancestors.

• Bi Cha gave Hu Yu one trillion Dreadnoughts to reinforce his expedition to Sextans.
• Hu Yu, Li Zhixiong, and Academician Qin Yin crossed the million-light-year Lost Zone after 125 years and headed for Sextans.
• Yan Xue’s Snow Tribe fleet was surrounded by a quadrillion ships from the Giant General Civilization and other local civilizations.
• The Giant General Civilization demanded Yan Xue’s password and attacked, but his fleet repelled their assaults by sealing off the fourth dimension.
• Yan Xue told Chen Xue to hold out and explained that he stayed because the enemy held their technology and the remains of their ancestors.

Yan Xue’s exhausted fleet faced capture by the Giant General Civilization until Hu Yu arrived with a massive fleet and destroyed the attacking forces. Hu Yu rescued Yan Xue and the Snow Tribe, leaving the rabbits to reunite with him aboard the ship.

• Yan Xue refused to surrender the Snow Tribe’s code as the Giant General Civilization’s robots moved in to capture his people.
• Fifty trillion black triangular warships appeared, and Hu Yu contacted Yan Xue and promised to handle the crisis.
• Hu Yu detonated two-dimensional bombs that destroyed ten trillion Giant General Civilization warships, then wiped out the remaining attacking fleets when they refused to retreat.
• The small star sector civilizations fled, while Hu Yu’s forces emerged without losing a ship and destroyed nearly half of Sextans’s advanced combat strength.
• Several rabbits rushed in through the hatch, and one leaped at Hu Yu and sobbed.

Hu Yu reunited with Yan Xue and learned that the Snow Tribe needed to recover its stolen technology backups from the Giant General Civilization. As Hu Yu prepared to attack three suspected locations, an unseen force immobilized the fleet’s warp travel, leaving the Conquerors moving slowly and braced for danger.

• Yan Xue told Hu Yu how the Snow Tribe had settled in Sextans, restored some of its original genes, and been hunted by the Giant General Civilization for its technology backups.
• Hu Yu agreed to help Yan Xue recover the backups, and he calmed Chen Xue after Li Zhixiong frightened him by pretending he wanted to eat him.
• Chen Xue’s team identified three possible locations for the Giant General Civilization’s home base, and Hu Yu gathered the fleet to attack them.
• Hu Yu discovered that an enormous, undetected energy surge had stopped the fleet’s warp travel, though its conventional engines still worked.
• Hu Yu canceled the plan to split the fleet and ordered the ships to move slowly together while preparing for a possible attack.

Hu Yu investigated why curvature travel had stopped throughout Sextans and split the Conqueror Fleet between searching for the Giant General Civilization and heading for the region’s outskirts. As the fleet struggled to travel using conventional power, the Giant General Civilization blamed a hidden god-level civilization for the crisis and spread that explanation across Sextans.

• Hu Yu and Yan Xue ruled out the Giant General Civilization and the Snow Tribe’s stored technology as causes of the fleet’s immobilization, and Hu Yu considered whether a hidden civilization or natural phenomenon was responsible.
• Qin Yin reported that curvature travel had failed throughout Sextans, so Hu Yu ordered the fleet split between leaving the region and searching the three sets of coordinates for the Giant General Civilization.
• The Conqueror Fleet lost contact with its base and found that it could neither enter the fourth dimension nor draw energy from it, forcing it to replenish its reserves from stars.
• Civilizations across Sextans panicked and suspected Hu Yu, while the Giant General Civilization concluded that his fleet’s use of conventional power made him unlikely to be responsible.
• The Giant General Civilization announced that a hidden god-level civilization had restricted the galaxy to drive out outsiders, and the message calmed the other civilizations.

Hu Yu's fleet lost contact across dimensions, forcing him to abandon the attack and flee as the Giant General Civilization gained the ability to enter the fourth dimension. The Giant General Civilization surrounded Hu Yu and Yan Xue's forces, and Hu Yu's attempt to use a two-dimensional fragment barely affected the enemy.

• Hu Yu lost contact with his fleets and pursued the Conquerors while sending the Snow Tribe onward, but the Superintelligent Robots could not descend into three-dimensional space and soon reunited with him.
• The Giant General Civilization discovered its fleet could enter the fourth dimension and gathered a hundred quadrillion warships to attack Hu Yu's fleet.
• The Superintelligent Robots in the fourth dimension attacked the Giant General Civilization, then revealed themselves and fought before fleeing after Hu Yu detected the battle.
• The Giant General Civilization sent eight billion warships into three-dimensional space, surrounding Hu Yu's and Yan Xue's fleets and using dimensional-reduction strikes against the Conquerors.
• Hu Yu launched a two-dimensional fragment, but it dissipated after reducing space over less than a few hundred meters.

The Giant General Civilization's dimensional strikes failed to destroy most of the Conquerors, so Hu Yu ordered the fleet to scatter and devastate Sextans while Qin Yin searched for the cause of the altered spatial rules. After Qin Yin discovered a new energy and the rules were restored, the Conquerors regained access to curvature travel and the fourth dimension, but their two-dimensionalization failed and the fleet was exposed in three-dimensional space.

• Qin Yin determined that the rules of space had been changed to favor the Giant General Civilization, and she proposed provoking whoever was behind the change by threatening Sextans.
• Hu Yu scattered the Conquerors across Sextans, where they destroyed celestial bodies and evaded the Giant General Civilization's attacks as its fleets suffered heavy losses.
• After more than two hundred years of destruction, Qin Yin discovered a rare energy with an unfamiliar Basic Space structure and named it Third Energy.
• Hu Yu found that the fleet could travel at curvature speed and enter the fourth dimension again, and the Conquerors regrouped.
• The rules' restoration prevented the Conquerors from two-dimensionalizing, leaving more than seven quadrillion Conquerors and one trillion Dreadnoughts exposed in three-dimensional space.

Hu Yu pursued the Giant General Civilization to recover Yan Xue’s technology, but the enemy lured his fleet into a devastating dimensional-reduction trap. After escaping with heavy losses, Hu Yu handed the problem to Li Zhixiong and demanded a plan.

• Hu Yu questioned Qin Yin about the changing rules and ordered the Dreadnoughts to threaten Sextans’s celestial bodies while the Conquerors searched for the Giant General Civilization.
• The Conquerors found the Giant General Civilization’s apparent base, and Hu Yu moved his fleet into three-dimensional space to pressure the enemy into returning Yan Xue’s technological reserves.
• The Giant General Civilization and allied fleets sacrificed at least twenty trillion warships to launch a dimensional-reduction attack near the base, destroying most of the Conqueror Fleet.
• Hu Yu ordered the surviving Conquerors to flee into the fourth dimension after their numbers fell from more than seven trillion to two trillion.
• Furious at being tricked, Hu Yu assigned the problem to Li Zhixiong, who said he had an idea.

Human Civilization sought allies in Sextans to weaken the Giant General Civilization, and Hu Yu’s liaison persuaded the Firmament Civilization to help locate its base. The Firmament leader agreed in exchange for the Giant General Civilization’s technology tree.

• Hu Yu argued that the civilizations of Sextans had suffered most of the losses under the Giant General Civilization and proposed driving a wedge between them.
• General Li approved seeking allies in Sextans B and the NGC 3109 galaxy instead of asking the Milky Way for help.
• Human Civilization secretly sent a spacecraft and robot into Firmament Civilization territory to contact its leader.
• The liaison promised the Firmament Civilization the Giant General Civilization’s technology tree in exchange for the coordinates of its base.
• The leader of Firmament agreed to find the coordinates, provided that was the only task required of them.

Li Zhixiong and Hu Yu sought allies against the Giant General Civilization, sending disguised Dreadnoughts to Sextans B and NGC 3109. After finding NGC 3109 utterly devastated, they attacked the Firefly Civilization in Sextans B while pretending to represent the Giant General Civilization, and the Aurora Civilization's fleet approached as the Dreadnoughts fell behind.

• Li Zhixiong arranged for civilizations in Sextans B and NGC 3109 to help humanity, while the Dreadnoughts were modified to resemble Giant General Civilization warships.
• The Dreadnought fleet reached Sextans B and found advanced civilizations there, then waited for the second fleet to arrive from NGC 3109.
• The second fleet found NGC 3109 destroyed and lifeless, so Hu Yu ordered the Dreadnoughts to withdraw and left miniature spacecraft to investigate.
• Hu Yu and Li Zhixiong chose to seek help from the Firefly Civilization and launched a surprise attack on its fleet in Sextans B.
• The Firefly Civilization recognized the attackers as the Giant General Civilization and counterattacked, while Hu Yu learned that the Giant General Civilization had secretly fought it before.
• Li Zhixiong taunted the Firefly Civilization as the Dreadnoughts fell behind its much larger fleet, and Hu Yu detected the approaching Aurora Civilization fleet.

The Firefly and Aurora Civilizations led 110 trillion warships toward the Giant General Civilization’s base in the fourth dimension, guided by the Dreadnoughts. As the battle began, Li Zhixiong sent the Conqueror to recover Yan Xue’s technology planet before the other civilizations could reach it.

• The Dreadnought escaped into the fourth dimension and later led the Firefly and Aurora fleets toward the Giant General Civilization’s base.
• Hu Yu praised Zhuge Xiong, while Yan Xue explained that only he could open the planet containing his people’s technology and buried dead.
• The Giant General Civilization detected the approaching fleets and summoned the Firmament Civilization and two others to defend its base.
• The Dreadnoughts revealed their identities and attacked as the Firmament Civilization and the other two civilizations turned against the Giant General Civilization.
• The Giant General Civilization sent warships to strike the three civilizations’ bases, but Hu Yu had already evacuated their people.
• Li Zhixiong ordered the Conqueror to retrieve Yan Xue’s planet, and Yan Xue’s fleet followed to help move it once secured.

The Conquerors and their allies overwhelmed the Giant General Civilization, but the battle stalled as the Giant General Civilization tried to escape with the Snow Tribe planet. When the planet revealed itself as a sealed four-dimensional silver sphere, Li Zhixiong’s forces and Yan Xue’s fleet moved to protect it and get close enough to claim it.

• The Conquerors joined five other civilizations in attacking the Giant General Civilization, whose fleet suffered heavy losses as it tried to evacuate its population.
• Yan Xue identified the planet the Conquerors needed to seize, and Li Zhixiong led the human fleet toward it through the Firefly Civilization’s assault.
• An energy wave stripped away the planet’s surface and revealed a silver sphere sealed against fourth-dimensional observation, drawing the attention of the other civilizations.
• The Giant General Civilization abandoned its escape attempt and gathered its remaining forces around the planet, while Li Zhixiong repeatedly attacked its defensive line.
• Yan Xue’s fleet joined the fight, using its strong defenses to shield the Conquerors as they advanced toward the silver planet.

The Firefly Civilization took possession of the silver planet, but Hu Yu confronted its fleet and explained that the Human Civilization had come to reclaim it. The Firefly Civilization agreed to return it if Hu Yu could prove ownership, and Yan Xue began unlocking the planet.

• The Giant General Civilization abandoned the silver planet and escaped into the fourth dimension, leaving it in the Firefly Civilization's hands.
• The Firefly Civilization prepared to leave with the planet, but Hu Yu blocked its path with the remaining Conquerors and Dreadnoughts.
• Hu Yu told the Firefly Civilization that his forces were the Human Civilization from the Milky Way and that they had come to reclaim the planet.
• The Firefly Civilization agreed to return the planet if Hu Yu proved it belonged to the humans.
• Yan Xue reached a magnetic pole on the silver planet and sank into its surface, which hardened again after he disappeared.

After Yan Xue frightened the Firefly Civilization with the silver planet’s speed, Hu Yu negotiated an alliance and warned them that NGC 3109 had been destroyed. The Firefly Civilization agreed to protect Sextans A and Sextans B, while the Human Civilization returned toward the Milky Way.

• The silver planet accelerated to fifty thousand times the speed of light and frightened the Firefly Civilization before returning to the Conqueror.
• Yan Xue emerged from the silver planet trembling and told Hu Yu that something inside had terrified him.
• Hu Yu asked the Firefly Civilization to take over Sextans A and warned them that NGC 3109 had been reduced to scorched earth.
• The Firefly Civilization agreed to safeguard Sextans A and Sextans B, and Hu Yu offered to share information and promised future cooperation.
• After the power of space returned to normal, the Conqueror and silver planet set off for the Milky Way.
• The Firefly Civilization’s leader offered the Aurora Civilization its tech tree, and the two civilizations agreed to protect both galaxies together.

Hu Yu and the others explored the silver planet, where Yan Xue discovered the Snow Tribe’s original form and watched a recording left by its second patriarch. The message revealed the tribe’s ancient enemies and warned that the Snow Tribe’s remains and technology must be kept secret.

• Yan Xue stayed aboard the Conqueror, but Li Zhixiong carried him after Hu Yu when the others explored the planet.
• Hu Yu saw billions of incomplete, cleaver-shaped warships and estimated that the planet might contain five to ten trillion of them.
• Hu Yu, Li Zhixiong, and Qin Yin found terrifying dead creatures covering the planet’s inner shell, and Hu Yu recognized them as the Snow Tribe’s former bodies.
• Hu Yu told Yan Xue that the creatures were his ancestors, and Yan Xue approached them in sorrow.
• A recording from the Snow Tribe’s second patriarch explained that genetic modification had changed the tribe’s bodies and that restoring their full abilities meant returning to their original form.
• The patriarch revealed that the Snow Tribe had 500 billion warships and warned Yan Xue to hide its remains from the Doomsday Civilization, the Knight Civilization, and the Deep Space Civilization.

Hu Yu and Yan Xue brought Snow Star and the Snow Tribe’s surviving warships out of the chaotic four-dimensional zone. Yan Xue began preparing to rebuild the Snow Tribe, though the 500 billion recovered ships were only a third-tier force.

• Hu Yu ordered Yan Xue’s people to hide in the chaotic zone, rebuild their technology, and prepare a fleet while Hu Yu considered threats to the Milky Way.
• Yan Xue explained that Snow Tribe ancestors had created the Lost Zone as a defensive barrier and had hidden Snow Star within it.
• After the silver planet crossed the Lost Zone, Yan Xue’s people brought Snow Star to Hu Yu, and rabbits gathered to hear about Yan Xue’s experiences in Sextans B.
• The Snow Tribe launched 500 billion folded warships, which expanded into enormous vessels when they left the silver planet.
• Yan Xue learned that the ships were an intact third-tier self-defense force rather than the Snow Tribe’s main fleet, and accepted that its peak technology had been lost with its ancestors.

Hu Yu returned from Sextans A with Snow Tribe technology and discovered that the Fish Horse Star Civilization was still attacking the Mirror Sub-Universe while its time advantage dwindled. He also learned that the Justice League had risen to power in the Milky Way during his absence.

• Yan Xue gave Hu Yu copies of the Snow Tribe's technological reserves, and Hu Yu advised him and the Rabbit leadership to avoid the Milky Way and study their silver planet's technology.
• Hu Yu returned to the Mirror Sub-Universe entrance and found a vast, heavily fortified system marked by frequent fleet deployments and warship wreckage.
• Zhonghua told Hu Yu that the Fish Horse Star Civilization had reinforced its Milky Way fleet with sixty trillion warships and continued to harass them after a major battle.
• Zhonghua explained that the superconduit's time advantage had fallen from a hundredfold to at most twofold as space and energy from the greater universe flowed into the Mirror Sub-Universe.
• Zhonghua told Hu Yu that more than twenty Great Star Region Civilizations had formed the Justice League, which controlled the defensive line and had driven nonmembers into extragalactic regions.

Hu Yu met with the leaders of the six great star region civilizations and reported the destruction of NGC 3109 and the strange restrictions he faced in Sextans A. The Demon Scorpion leader revealed that evidence from Fish Horse Star Civilization wreckage pointed toward the Boötes Dwarf Galaxy as its possible home.

• Hu Yu chose to send Gao Jianchuan, Academician Qin Yin, and the others to the science ship while he traveled to the Yun San Civilization.
• Hu Yu told Leader Yun San that he had failed to find his people in Sextans A, where altered rules had nearly destroyed his fleet, and reported that all life in NGC 3109 had been wiped out.
• Hu Yu and the leaders discussed the threat posed by the Fish Horse Star Civilization and their inability to locate its base.
• The Demon Scorpion leader said analysis of contamination on Fish Horse Star Civilization wreckage suggested the civilization might have come from the Boötes Dwarf Galaxy.
