Background / History

Transmigration and Dania’s Rescue

Zhou Yu was a player with roughly three thousand hours of experience in the game. After angrily demanding a refund and striking his keyboard, he awoke at the Lahai-Roi Defense Line in a logistics uniform, holding a rock-hard baguette. He recognized the scene as Dania’s impending sacrifice from version 3.3 1 4.

Rather than accepting her death as destiny, he struck her with the baguette and interrupted her ritual by demanding to know who would eat her unpaid birthday cake. When Aleph One attempted to erase him, Zhou Yu used his newly acquired access to the game’s underlying mechanics to permanently block its number 1.

He then began giving Dania experiences unrelated to her role as a vessel: a shared meal, a birthday dress, cake, and a wish requiring nobody else’s approval. After protecting her birthday candle from the wind, he left the battlefield with Dania and Sigelica, heading toward Flamebearers' Academy 3 8 10 12.

Life at Flamebearers' Academy

Headmistress Lupa identified Dania as Cradle, a highest-grade vessel intended to contain and counteract Aleph One’s will through a fatal operation. When Lupa offered Dania protection under the academy charter, Zhou Yu immediately asked what conditions accompanied it 15.

At the academy, he received a cafeteria-taster appointment and began supervising food quality and portion sizes. He also built a social circle around Dania, arranging sweet-sharing meetings with Aimis and accompanying the group to Flying Snow Velvet’s concert 17 20 22 32.

His routine work concealed substantial security interventions. He neutralized five resonance bombs and three assassins through a campus cleaning mechanism, sold the resulting scrap for thirty star coins, and bought Dania ribs and orange soda with the proceeds. He also challenged suspicious transfer paperwork when Yeqi’s interest in Dania raised concerns 35 61 62.

Romance and Security Work

Zhou Yu and Dania’s relationship developed through shared meals and outings. They held hands at Starlight Amusement Park; when she confessed her feelings aboard the Ferris wheel, he gave her a written meal schedule. He subsequently accepted her public claim on their relationship and reserved time exclusively for the two of them 40 42 43 44.

His growing security responsibilities sometimes disrupted those promises. After missing meals and leaving Dania waiting, he reconciled with her through a personal visit, sweet-and-sour ribs, and a signed month-long dessert compensation schedule 76 77.

When the academy’s physical assessment incorporated a replica of the Lahai-Roi battlefield, he concealed the notice from Dania and prepared for the danger posed by both the setting and her overwhelming strength. He commissioned disguised kinetic-energy-absorbing guards from Chisaki and arranged an overnight power shutdown after detecting surveillance probes 77 78.

Seaside Travel and Jinzhou

Zhou Yu argued against keeping Dania permanently confined behind the academy’s protective barrier, insisting that she should see the sea and experience places beyond the cafeteria and logistics warehouse. Chisa joined the subsequent journey as a vigilant escort and imposed separate sleeping arrangements after ten at night 85 87.

During the South Sea stay, he secretly stopped a fifty-meter tsunami by setting the water’s maximum height to half a meter. He concealed the intervention from Chisa, attributing the disturbance she noticed to a possible ice-maker vibration 91.

In Jinzhou, Qiu Yuan’s investigation drew his attention when stolen materials proved to bear the academy Logistics Department’s seal. Zhou Yu negotiated reimbursement before helping investigate the circus-linked thefts, uncovered the concealed resonance-material cache, and recognized that Changli had arranged the clues to bring him to her residence 98 99 101.

On the subsequent mountain assignment, he used collision manipulation against trapped road structures and opened a maintenance passage to release sluice water against a Dreamless afterimage. Afterward, he arranged recuperation at public expense and secured Changli’s approval for the team’s fieldwork costs 103 107 112.

Black Shores and the Broadcast Incident

Zhou Yu chose the Black Shores as both a vacation destination and a place to investigate Aleph One. There, he could perceive hidden disturbances in a star chart even without his watch. At the Tethys computational core, the disturbances synchronized with his heartbeat, and the system detected a “shared-origin low-level access language” 112 115.

Camellya questioned how he had changed Dania’s fate and asked him to help create a future without the Tethys System’s sacrifices. He declined to commit, treating the proposal as an inadequately compensated job. He also encountered the mysterious Black Shores administrator, whom Aimis recognized as her father 123.

During Chisaki’s registry review and the ensuing city crisis, Zhou Yu supported her investigation while reassuring Dania that he would keep her name on his schedule. He and Chisaki ultimately ended the tower’s decades-long backward broadcast by allowing its recording to run forward to completion. The tide stopped, the Tacet Discords dispersed, and Dania’s observation period was revoked. Zhou Yu recorded her as his traveling companion 130 136.

Appearance

• Facial features: Long eyelashes, a high nose bridge, and a sharply outlined profile; his eyes are often described as languid 41 44.
• Work clothing: Initially wears a Lahai-Roi logistics uniform; later becomes recognizable for his yellow utility repair vest and work boots 1 34 35.
• Inspection identifiers: Wears a red “Quality Inspection” armband and a “Cafeteria Supervisor” badge while overseeing meal service 20.
• Vacation clothing: Favors floral shorts, a loose white tank top, and flip-flops or slippers—even when visiting Changli’s residence 89 101 112.
• Usual accessories: Carries an old-fashioned digital watch, a canvas bag, and a thermos of goji berry tea 35 52 103.

Personality

Zhou Yu is irreverent, outwardly lazy, and deeply suspicious of unpaid work. He frames threats, divine interference, and political requests in the language of overtime, reimbursement, performance reviews, and workplace regulations. Even after averting disasters, he insists on compensation and carefully reads contracts for holiday pay and uncapped bonuses 54 69 71 99.

His apparent flippancy conceals a firm rejection of treating people as expendable tools. He replaces Dania’s sacrificial combat outfit with a birthday dress, insists that her wishes need no authorization, and challenges the idea that safety should require lifelong confinement. With Chisa, he similarly questions the responsibility of sacrificing tomorrow’s lifespan for today’s strength 8 10 85 131.

He expresses affection through practical care: cooling food, remembering preferred cuts of ribs, preparing drinks, arranging meals, and making time in writing. His schedules become promises of continued companionship rather than mere organizational tools 34 42 77 130 136.

He is also mischievous and exacting. Friends caught spying on him receive fines, warehouse-cleaning duties, and suspended meal privileges, although he still gives them roasted sweet potatoes before work. When an investigation risks becoming violent, he insists on evidence and handing offenders over through proper procedure 60 109.

Abilities & Skills

Underlying Game-System Access

Zhou Yu’s original transmigration ability is a player’s access to the game’s underlying mechanics. Its interfaces appear as crude menus, watch displays, and code-entry screens 1 44 91.

• Command blocking: Permanently adds Aleph One to a spam list, stopping its immediate attempt to erase him 1.
• Backend commands: Opens an interface visible only to him and enters customized countermeasure instructions 44.
• Status manipulation: Resets Dania’s satiety during a seafood buffet 70.
• Access recognition: Tethys detects a shared-origin low-level access language in his presence; the passage does not establish the full nature of that connection 115.

Physics and Collision Manipulation

He can exploit or alter collision behavior rather than overcoming obstacles through conventional force 3 45 91 103.

• Restricted-area access: Uses a known five-minute disappearance of a supply-lock collision check to enter a military storeroom 3.
• Machine exploits: Manipulates claw-machine input delay, tags, and mismatched collision boxes to win Dania stuffed toys 45.
• Environmental editing: Reduces a tsunami’s Z-axis peak height from fifty meters to a locked maximum of 0.5 meters, using his watch and appointment letter 91.
• Structural interference: Sets pavilion supports’ Z-axis collision volume to zero, causing a reinforced structure to collapse despite its talisman array 103.

Rule Enforcement and Administrative Mechanisms

Zhou Yu turns maintenance notices, institutional authority, and regulations into practical defenses 35 54 69.

• Sanitation cleanup: Activates a mechanism targeting non-fixed-asset trash and negative energy; resonance bombs become scrap, while the assassins are compelled to clean 35.
• Paid-leave protection: A stamped “On paid leave, do not disturb” sign triggers rule enforcement that returns a high-energy intruder to a waiting area 69.
• Maintenance intervention: Stops a warehouse alarm with a shutdown notice and opens a temporary maintenance passage with a voucher 54 107.
• Procedural obstruction: Challenges a suspicious transfer student’s admission through missing mandatory records 61 62.

Detection and Investigation

His system warnings supplement close observation and knowledge of game behavior 20 91 115.

• Threat alerts: Receives warnings about hostile activity, altered weather controls, high-energy intrusions, and tampered physical laws 66 68 91.
• Hidden-data perception: Identifies ten dark patches concealed behind the Black Shores star chart without relying on his watch 115.
• Search assistance: Reveals walls, compartments, pipes, and people through structures within a hundred meters during the talisman search 110.
• Behavioral analysis: Infers Chisa’s use of Prefetch from her faster sword strike and slower completion of paperwork 131.

Improvised Combat and Battlefield Planning

Zhou Yu relies on terrain, timing, tools, and enemy behavior rather than formal combat displays 7 106 132.

• Environmental weapons: Flips a sewer grate into a Fractsidus Stalking Spider, then destroys its energy core with a hardened baguette 7.
• Low-cost countermeasures: Defeats an expensive infrared security installation using a ten-credit mirror 27.
• Terrain exploitation: Releases water to weaken the Dreamless afterimage while Chisa holds it back 107.
• Team coordination: Calculates a building’s blind spot so Sigelica can force a Stonewall Bracer into Chisa’s attack path 132.

Logistics, Repairs, and Food Preparation

His ordinary professional skills remain central to the group’s daily life 20 59 72.

• Mechanical repair: Disassembles malfunctioning patrol robots and works with wiring, casings, screws, and tools 59 72.
• Food supervision: Inspects serving portions, food quality, and recipe consistency 20 43.
• Cooking: Prepares meat-and-potato stew, caramel popcorn, barbecue, and seafood 3 45 89 90.
• Purchasing and negotiation: Uses inspection standards and ingredient analysis to bargain; at one night market, he drives prices down by thirty percent across the street 68.
• Budget management: Secures fieldwork reimbursement and allocates the proceeds to equipment, bonuses, and paid leave 112.

Equipment / Weapons / Items

• Old-fashioned digital watch — Main portable interface for warnings, countermeasures, target identification, and physics commands 44 91 122.
