Power Progression

Body and soul cultivation are tracked separately. Cheng Yu’s equipment, titles, and borrowed authority frequently let him fight beyond his personal realm; their ranks do not represent his own advancement 160 171 440.

Stage / Realm / Level	Chapter	Notes
Black Iron Three-Star	29	First recorded personal rank. His Heart-Bewitching Spell is also Black Iron Three-Star; he remains at this personal rank through the end of the initial conquest 73 83.
Black Iron Four-Star	85	Reached after practicing a meditation method created with the Infinite Technique.
Body: Black Iron Five-Star	89	Achieved by consuming a High-Energy Crystal Block. Further consumption is discouraged because his soul has fallen behind his body.
Body: Bronze One-Star	96	Uses fifteen crystal blocks. Gains a leakless body; vitality rises to approximately 1,300, with recovery of 130 per second.
Body: Bronze Five-Star	111	Confirmed before he begins attempting his soul’s Bronze breakthrough.
Soul: Bronze	111	Reached through repeated Breakthrough Formation attempts. Gains detailed nearby perception; virtual-arena health reaches approximately 110,000.
Soul: Bronze Five-Star	144	Absorbed Weird energy raises his soul through the Bronze stars. He can faintly distinguish the condition of microscopic organisms.
Soul: Silver	171 337	Confirmed before his body’s Silver breakthrough. His perception covers most of Capital City; he later recalls needing over a thousand attempts to reach Silver.
Body: Silver One-Star	171	Achieved on the third attempt using energy obtained from the fully digested Sphinx.
Body: Silver Five-Star	171	Continued absorption of Sphinx’s energy carries his body through the Silver ranks.
Body: Gold One-Star	171	Achieved on the eighth attempt at the Gold barrier. Unlocks perception and manipulation of the fundamental “strings” composing matter.
Soul: Gold One-Star	337	Uses Mad God’s drained power for Talent Enhancement, then succeeds on the eighth Breakthrough Formation attempt. Both body and soul are subsequently confirmed at Gold One-Star 440.
Body and soul: Gold Five-Star	503	Both reach the material limit, satisfying the dual-rank prerequisite for Legendary advancement.
Void Legendary	751	After a failed attempt destroys his body, his surviving Gold Five-Star soul follows an unusual route through the Void. He completes a Rule Body by absorbing a rule-creature from within, nearly losing his memories and identity 748 751.

Background / History

Transmigration and Yog’s Patronage

Before transmigrating, Cheng Yu had few friends. He later learns that his transmigration itself was caused by Yog’s authority fragments. After enduring roughly a year of Lin Mo’s attacks, he eagerly accepts Yog’s offer to become his agent 3 49 413.

His first supplied assignment is to thoroughly embarrass Lin Mo. At Li Xuehong’s birthday banquet, he presents the valuable Tear of the Green Forest, borrowed from collector Old Wang. Xuehong still prefers Lin Mo’s handmade gift, but Lin Mo fails his own system mission and Cheng Yu’s assignment is marked complete 3.

Yog subsequently upgrades his system into the Strongest Wage Earner System. Cheng Yu pledges to recover his patron’s authority fragments, combining gratitude with hopes of personal advancement. Before leaving his ordinary employment, he repeatedly tries to resign from Li Ming’s service; Li Ming instead offers extended leave and continued support 5 22.

Keynes Continent and the Mechanical Legion

Cheng Yu conquers the Monster Forest and kills its Beast Lord, then invests the territory’s resources in stronger military units, energy production, and troop transport. The continental coalition later exposes the limits of his Purger-based army through coordinated bombardment, elite troops, and reserved Earth Elementals 29 65.

When an Abyss gate destabilizes space, he returns to the Monster Forest despite Conductor’s warning. His Epic title protects him during the journey, allowing him to upgrade his research infrastructure and deploy the Enabler and Annihilator series before returning to the war against the First Calamity 74.

San Lorenzo World and the Weird Kings

Cheng Yu enters San Lorenzo World as a Sea City University student with an assigned history as an orphan raised in boarding schools. His identity includes a paid marriage of convenience with Lü Youying, giving him a campus reputation as a “kept man.” He concentrates on cultivation while avoiding conspicuous use of his mechanical army, which could attract the World Consciousness’s attention 85.

He befriends the powerless transmigrator Luo Xia, initially regarding him as a useful source of plot information. Their alliance becomes a protective brotherly relationship: Cheng Yu supplies armor, escape tools, and a formation that redirects Luo Xia’s memetic contamination onto himself 91 93 103 111.

During the Great Expedition, Cheng Yu secretly boards the Wings of Hope, purchases the Pure White Emissary, and confronts the General in Yingzhou. After defeating the General and Xiao Ge Ruan, he returns to the stranded ship and transfers it directly to Capital City’s harbor 124 128 133 150.

He accepts nominal leadership of the Human Nation’s Supreme Military Commission chiefly to obtain intelligence about the Weird Kings. His battles with Sphinx and the paired Dark Man and Bloated Daughter reveal that prepared opponents can exploit his reliance on equipment and escape techniques. The destruction of Sea City also costs him nearly all the ordinary acquaintances he had made there 152 161 179 180.

Cheng Yu establishes Hunter under Luo Xia, later resigns amid the Human Nation’s political crisis, and agrees to help Zhou Qianyan’s world only insofar as it does not conflict with his goals. After his death and revival in a restored, merged worldline, he scatters Zhou’s ashes, says farewell to Luo Xia and Lü Youying, and leaves with Yog 164 186 196.

Small Heavens and Kashi Star

In the sandbox world, Cheng Yu assumes the identity of the reincarnated Herman Reginald, founder of the Second Dynasty. He recruits the player Shining Girl while investigating the world’s creator, its relationship to the Small Heavens, and possible traces of Yog’s authority fragments 206 211.

Miss Puppet later grants him the Legion’s highest command authority and Deputy Core status. After defeating the Pirate Allied Army, he secures control of the B3397 Universe and travels to Kashi Star to investigate the wider powers more discreetly 315 337 338.

On Kashi, he attends Miskatonic University as Yuri Constantine and joins the Azure Dragon Study Group. Five years of shared danger create bonds he considers deeper than ordinary friendship. Nevertheless, he refuses Bennett’s invitation to help build a new Balchik era when Bennett will not surrender its Creator Godhead Fragment, accepting that their missions may eventually put them on opposing sides 340 413 418 420.

When he returns, seventy-three years have passed on Kashi Star. He visits the dying Dile, attends his burial from a distance, and honors the surviving traces of his old companions. He also wishes Shui Feifei well at her wedding to Xiao Ming rather than resenting her changed affections 501.

Shen Yu and the Demon Race

Cheng Yu shares Shen Yu’s body and occupies his position within the Demon Race, planning internal purges and a wider strategy involving Shen Qian. He intends to settle the race’s crisis before entrusting its future, the Demon Dynasty, and the younger generation to Shen Yuan 577 627 629.

During confinement in the Jade Bamboo Grove, he alternates between resting as himself and merging with Shen Yu for prolonged cultivation. After ten thousand years, the barrier has weakened enough for him to believe he could break it, but he refuses: his agreement requires the Eternal Heavenly Dao to release him 599.

He later eliminates the Heavenly Demon Tide in three steps and accepts the risk of an attack from the Abyssal Will. Mythic power overwhelms him, forcing Shen Yu to take control. Shen Yu explains that Cheng Yu could use only about seventy percent of his strength 627.

Yunyangzi’s Mortal Journey

After returning to his own form, Cheng Yu undertakes Yunyangzi’s wish in a severely weakened condition. His refined bearing and white clothing repeatedly cause others to mistake him for a powerful cultivator, although he struggles with hunger, money, travel restrictions, and an inability to absorb spiritual energy through the heaven-disliked body 629 632 634 699.

Traveling with Niu Ba, he crosses the Eternal True World while avoiding the political schemes he once influenced as a Demon Race Great Sage. He also escorts Shen Qian toward the Northern Abyss Islands, though a confrontation among major human and demon figures ultimately exceeds his ability to control 653 675 731 732.

Shen Yue grants him an empowered Jade Token to ease his travels and help locate Stillwater’s remains. Near the end of this life, Cheng Yu returns to Verdant Micro Mountain, buries Stillwater, destroys Niu Ba’s Spirit Beast Contract, and dies peacefully in meditation inside the Taoist Temple 734 742.

Legendary Advancement and Self-Directed Life

Cheng Yu is active again after the conclusion of Yunyangzi’s life. Asked by the God of Amusement to act according to his desires, he identifies shelter and greater strength as his immediate priorities. He studies Shen Yu’s breakthrough memories without simply copying them, then pays the System to isolate his surroundings from the Eternal True World’s Heavenly Dao and connect them to the Chaos Sea 745 746.

His eventual Void Legendary breakthrough nearly erases his identity. Once successful, he pays twenty-five million currency to restore the appearance of his misshapen True Form. With urgent missions temporarily absent, he explores a more self-directed life and becomes a protective guardian-like figure to Snow Spirit 751 753 767 780.

The Apostle’s Summoning and the Road to Epic

Using the Silver Key and Yog’s Aura, Cheng Yu perceives overlapping timelines and possible worlds. He anchors a summoning array to his past and alternate selves, distributes Yog’s authority fragments across those possibilities, and calls upon the Big Shot’s true form as an Apostle 829.

He subsequently chooses an Epic advancement method based on plundering other Legendaries’ essence and mastered rules. He has not yet reached Epic in the supplied material. His later activities include analyzing Legendary remains, repairing the Pure White Emissary, and entering another world as Marquis Yuri Constantine 833 839 840 846.

Appearance

• Typical features: White-jade skin, jet-black hair, sculpted facial features, and a handsome, well-proportioned build 97 340.
• White attire: The Pure White Emissary forms an ornate all-white outfit, contrasting sharply with the General’s black armor 128 133.
• Cultivation changes: His Bronze breakthrough initially removes his hair and pores. He restores his hair through an experiment that dangerously creates independent Weirds 96.
• Slow outward aging: He still looks unchanged when Luo Xia is thirty-five, and Jimmy later remarks on how little he has changed after seventy-three years 186 502.
• Variable forms: He appears in an infant body during the Herman Reginald impersonation, and his Kashi appearance differs from his sandbox-world appearance 206 211 376.
• True Form: His Void Legendary transformation leaves it misshapen; the System restores its original appearance for a fee 751.

Personality

Cheng Yu is irreverent, theatrical, and fond of showing off. He exaggerates his loyalty to Yog, trades insults with the System, and uses acting to manipulate impressions—whether securing permission to skip class, impersonating an arrogant monarch, or concealing his strength from fellow students 3 87 206 344.

His ingenuity is paired with reckless curiosity. He repeatedly turns unusual ideas into practical techniques, but his attempt to transform shed hair into living extensions nearly kills him. Defeats and later vulnerability make him more cautious: he learns that retreat is not always possible and increasingly avoids conflicts that offer him nothing 96 161 703 728.

He is compassionate without considering himself universally responsible for others. He protects Luo Xia, apologizes when his ship transfer drenches civilians, respects Lü Youying’s wishes, and cares for Snow Spirit. Conversely, he refuses to assume risks that strangers knowingly chose for themselves 111 114 150 182 780.

His mission can override even cherished relationships. Leaving Bennett and the Azure Dragon Study Group hurts him, but he does not abandon his objective. Over time, repeated farewells deepen his appreciation of ordinary companionship, promises, and the freedom to choose one’s own path 420 501 599 702 742.

Abilities & Skills

Infinite Technique

A Gold Five-Star ability gifted by Yog after Cheng Yu helps recover an authority fragment. It constructs effects through imagined formulas and supporting logic, spending life force to realize them 85 87.

• Cultivation: Creates meditation, food-conversion, Talent Enhancement, and Breakthrough Formation techniques 84 87 337.
• Utility: Simulates photographic memory, flight, shrinking, divination, and compound spells anchored to objects 87 103 118 344.
• Combat: Produces restraints, composite attacks, spatial techniques, and effects that activate Yog’s authority fragments 160 179.
• Testing: Cheng Yu uses an internal virtual training ground to develop techniques and inspect their life-force costs before deployment 87 96.
• Limits: Incomplete reasoning can make an effect prohibitively expensive. His initial food-conversion attempt costs two-thirds of his simulated health; refinement reduces it to one-quarter 87.
• Epic-level output: Can briefly produce an Epic strike by sacrificing life force; this does not make Cheng Yu an Epic being 833 834.

Devouring and Energy Conversion

Cheng Yu develops several techniques that convert food, specters, and defeated opponents into strength or knowledge.

• Food absorption: Strengthens body and soul; cooked food works as well as raw food 87.
• Specter-Devouring Pattern: Absorbs specters through skin contact and draws energy from physically embodied Weirds 89 92.
• Combat variants: Uses Weird-Devouring arrays, Ghost-Eater Blast, and Ghost-Devouring Lightning Pattern against groups of enemies 133 161 179.
• Final Devour: Creates a spatial stomach that digests its contents and transfers the resulting energy to the Pure White Emissary 171.
• Myriad Devouring: Drains Mad God to fuel soul enhancement and advancement 337.
• Rule acquisition: Consumes souls or analyzes Legendary remnants to deepen his understanding of a world’s rules and the route to Epic 839 860.

Spatial Techniques and Borrowed Authority

His spatial abilities range from practical teleportation to effects powered by Yog’s authority fragments.

• Transfers individuals, anchors limited-use escape spells to crystals, and moves the entire Wings of Hope to another harbor 103 124 150.
• Uses Spatial Movement with Cognitive Disruption to enter locations unnoticed 115.
• Borrows Yog’s supreme spatial authority to seal off an entire world and strip Sphinx of his spatial definition, collapsing the associated time dimension 160.
• Employs Space-Fixing Spell and the Black Box Spatial Slaughter Technique in battle 179.
• Limits: Activating borrowed authority can completely exhaust his vitality. Sphinx also proves that Cheng Yu cannot assume teleportation will always provide an escape 160 161.

Matter Manipulation and Perception

Gold advancement lets Cheng Yu perceive the vibrating strings that compose matter. His later Legendary awareness becomes extensive enough to encompass everything in a universe 171 840.

• Makes a desk disappear by manipulating its fundamental components 171.
• Creates blood to fake an injury while maintaining his student disguise 344.
• Attempts to reverse hostile alterations to his brain, though world-power reinforcement forces him to rely on the Infinite Technique instead 178.
• Perceives microscopic organisms at Bronze soul levels and much of Capital City after reaching Silver soul cultivation 144 171.
• Blank-slate Gold: His title prevents universal “erosion.” This frees him from ordinary Gold beings’ universal constraints, but denies him their full rule-based abilities 171.

Mind, Memory, and Concealment

• Heart-Bewitching Spell: Makes creatures with weaker souls believe his words. Cheng Yu selects it for influencing people around Lin Mo rather than relying on direct force 5.
• Cognitive Disruption Spell: Conceals his presence during infiltration and his secret boarding of the expedition ship 115 118 128.
• Memory manipulation: Alters residents’ memories after questioning them and searches memories for investigative clues 118 133.
• Acting: Maintains false identities and disguises both weakness and strength; his performances range from Yunyangzi’s composed bearing to the supposedly exhausted Marquis Yuri 634 846 860.

Mechanical Legion Command

Cheng Yu directs military production, research, resource allocation, and campaigns through the Legion’s command infrastructure.

Development	Chapter	Capabilities gained
Level-three city and research upgrades	29	Resource conversion, satellite mapping, Model 0-4 siege units, Model 0-5 aerial carriers, energy conversion, and short-range space-jump transport.
Enabler and Annihilator series	74	Specialized responses to nonmaterial energy and exceptionally powerful individual opponents.
Highest Authority / Deputy Core	315	All Legion facilities and all RTX Destroyer series except the Reforger; research advances to its current maximum.

• Strategic support: Conductor supplies casualty reports and practical assessments; Wisdom units develop strategic plans 29 64 65.
• Transport restriction: Paired space-jump rods transport only Legion members and require matching placement within 0.1 millimeters 29.
• Material costs: Research and custom units can consume enormous quantities of steel and rare metals 74 93.
• Deployment risk: Large-scale Legion use can attract a world’s attention; Cheng Yu judges a single custom armor unit less conspicuous 85 93.

Shen Yu’s Shared Power

This is borrowed access to Shen Yu’s body and strength, not Cheng Yu’s independent cultivation rank.

• Alternates between his own identity and merged cultivation with Shen Yu during confinement 599.
• Erases the Heavenly Demon Tide in three steps while occupying the shared body 627.
• Can command approximately seventy percent of Shen Yu’s strength; Shen Yu retains superior mastery and can independently take control 627.
• Later uses Shen Yu’s memories as breakthrough guidance while deliberately avoiding direct imitation of his path 746.

Equipment / Weapons / Items

• Strongest Wage Earner System — Yog’s upgrade replaces mission-centered mechanics with achievements, a shop, and paid lottery draws. The System describes itself as an intelligent program attached to an authority fragment; its small share of spacetime authority transports equipment and items 5 18.
• The Kid Watched by the Big Shot — Epic title, also rendered “The Kid Under the Boss’s Gaze.” Grants discounts, three prize choices per lottery draw, protection against lesser information contamination, monthly portions of Yog’s Aura, a right to refuse actions involving Yog’s authorities, and potentially endless life while Yog continues watching him. It also sustains his Bronze body and blocks even Mythic mind-reading 5 96 718.
• World-Destroying Savior — Special title that greatly increases damage against world consciousnesses and grants exceptional luck within a world. Cheng Yu equips it before facing the Abyssal Will 83 627.
• Deep Sea Slaughterer — Gold title listed among his possessions; its effects are not expanded in the supplied passages 73 440.
• Pure White Emissary — Legendary equipment purchased for ten million currency. Its nine white orbs form clothing and controllable weapons; it repels whatever Cheng Yu defines as “filth,” increases damage against it, and expends stored power to purify it. Its construction combines Repulsion, Purification, Annihilation, and Consciousness; its Annihilation component requires replenishment 128 840.
• Mad Song Fun Blade — A grotesque blade formed from smiling faces. Its revealed sequence makes a target cheerful, then an idiot, then subjects it to devouring on the third slash. Give It Here! also lets its faces gnaw through space 638 663 833.
• Yog’s Authority Fragments — Enable borrowed supreme spatial power and serve as components in his summoning array across timelines and possibilities 160 829.
• Big Shot’s Aura — Epic resource supplied through his title; used in his unusual Legendary advancement and Apostle summoning ritual 5 748 829.
• Silver Key — Allows him to perceive overlapping timelines and possible worlds, protecting him alongside Yog’s Aura while he constructs the multiversal summoning array 829.
• Shen Yu’s Memories and Insights — A golden orb containing a Holy Spirit’s experiences, including the process and precautions of Legendary advancement 746.
• System Space — Stores supplies, equipment, and other resources. After capturing a Legendary opponent, Cheng Yu believes only Mythic intervention could enable that prisoner to escape 634 663 780.
• Travel tokens — Liang Fei’s Identity Token permits free teleportation-array use along part of his mortal journey; Shen Yue’s empowered Jade Token grants access, official assistance, territorial information, and emergency transport to the nearest Demon Race city 675 734.

Relationships

• Yog / Big Shot — Patron and mission-giver. Cheng Yu’s extravagant flattery gradually accompanies real trust and commitment; Yog values the interesting drama and humanity he brings rather than demanding worship 3 5 111 229 829.
• The System — Guide, instructor, and constant sparring partner in sarcastic exchanges. It warns him about lethal experiments, assists his breakthroughs, and comforts him after leaving his friends 96 420 746 751.
• Miss Puppet / Big Sis — Powerful supporter who grants him the Legion’s highest authority. Cheng Yu remains warmly attached to her even when he notices changes in her behavior 315 501.
• Grete / Doggy — Companion associated with Yog. Their teasing relationship includes Cheng Yu interrupting a dangerous spiral of speculation with a slap 124 211 501.
• Luo Xia — Fellow transmigrator, protected younger-brother figure, secretary, and eventual leader of Hunter. Cheng Yu leaves him the silver armor-watch as a keepsake when Luo Xia chooses to remain in San Lorenzo World 91 93 152 164 196.
• Lü Youying — Wife in an assigned marriage of convenience; called “Lü Xiaoying” in the Chapter 85 summary. Cheng Yu has no romantic love for her, but prevents her father from striking her and gives her an honest farewell 85 182 196.
• Lin Mo — Early adversary whose repeated attacks precede Cheng Yu’s recruitment by Yog. Cheng Yu’s first supplied mission specifically targets Lin Mo’s public humiliation 3.
• Wan Zhuo — Reincarnator tied to Lü Youying and Luo Xia’s troubles. Cheng Yu monitors him as a marker of major plot developments and promises Luo Xia the chance to deal with him personally 115 124 171.
• Li Ming — Employer and paternal acquaintance addressed as “Uncle.” He resists Cheng Yu’s resignation and offers continued financial support; he also mistakenly believes Cheng Yu is courting Xuehong 3 22.
• Li Xuehong — Someone Cheng Yu explicitly regards as a younger sister rather than a romantic interest 3.
• Conductor — Dependable military aide who supplies reports, strategic advice, and warnings Cheng Yu does not always follow 29 65 74.
• Bennett / Old Bei — Close Kashi companion whose ambitions conflict with Cheng Yu’s fragment-recovery mission. They part with mutual recognition of their separate goals rather than pretending the conflict does not exist 413 420.
• Dile — Azure Dragon Study Group companion. Their friendship survives Dile’s resentment; Cheng Yu visits him at the end of his life and quietly attends his burial 420 501.
• Ning Qing and Tang Lan — Fellow Azure Dragon companions from his years on Kashi. By Dile’s death, both have already died and are buried beside him 413 501.
• Shui Feifei — Former admirer and a participant in Cheng Yu’s staged plans. He later congratulates her on marrying Xiao Ming without jealousy 229 231 501.
• Zhou Qianyan — Human Nation chancellor and longtime acquaintance whose devotion to his country Cheng Yu respects. Cheng Yu fulfills his request to scatter his ashes across the world 186 196.
• Shen Yu — Independent Holy Spirit whose body and memories Cheng Yu shares. Shen Yu acknowledges his service to the Demon Race but warns against merely copying his path 627 629 746.
• Shen Yuan, Shen Qian, Shen Tian, and Shen Yue — Family connections through Cheng Yu’s Shen Yu identity. He entrusts the Demon Race’s future to Shen Yuan, escorts Shen Qian, and remains affectionate toward the younger generation 521 577 731 734.
• Niu Ba / Bullie / Niu Niu — Ox companion throughout Yunyangzi’s journey. Cheng Yu offers him freedom early on, respects his decision to retain the protective contract, and finally releases him before dying 653 742 757.
• Ji Han — Demon Suppression Guard whom he previously rescued. Their repeated encounters culminate in paid work and financial help, though Cheng Yu does not share her trust in the Heavenly Dynasty 677 699 702.
• Tian Jianbai — Courteous Cavern Mystery expert who appreciates Cheng Yu’s reflections on the Dao and later warns him away from danger 705 728.
• Snow Spirit — Childlike companion with an affectionate, guardian-and-child dynamic. Cheng Yu explicitly says she is not his daughter and encourages her to develop independence through study 767 780 785 787.
• Shi Lian / Lian’er — Woman he rescued from her former brothel life. At their reunion ten years later, he respects her chosen life but questions whether her devotion is love or gratitude; his answer remains unresolved 787.
• Mu Feng — Legendary acquaintance who supplies the body-restoration crystal and Silver Key before Cheng Yu’s Apostle ritual 798 829.
