Qin Yiguan

Biodata

Power Progression

Recorded development after the Fusion Rate increase:

• Later discrepancy: Chen Mudou still refers to his Fusion Rate as zero during the fortress mission; no explanation is provided in the supplied material 48.
• Separate personality: Black Calamity’s 89% Fusion Rate belongs to the independently manifested dark personality, not Qin’s own recorded rate 38.

Background / History

Qin’s adoptive parents worked as core technical staff for the Gemini Superbrain. When he was six, Officer Wang found them stabbed to death, with Qin hiding beneath a table holding a bloody dagger. He had blood on his face and flesh from his adoptive mother’s arm in his mouth 9.

With the murders unresolved, Qin was sent to an orphanage in Rust City. Psychologists monitored his behavior, psychological indicators, and microexpressions for ten years, finding no violent or criminal tendencies in his ordinary personality. Believing he had lost his memories, the adults told him that his parents had ascended with the Gemini Superbrain 10.

Qin privately knew that his parents were dead. His claimed amnesia was an act, although his memories remained hazy. He suspected that another self inside his body had murdered them and deliberately swallowed the flesh to preserve his memory of the incident. Black Calamity’s later appearance confirmed the dark personality’s identity 10 38.

His brain disorders made him a Castoff, unable to sustain prolonged neural connections. By his hundredth nutrient-pod application, he was still being rejected: Officer Wang explained that pods had caused fatal cerebral nerve dissolution in people with brain defects and would be particularly dangerous for him 5 12. At the opening of the story, he had also refused his prescribed “Happy Pills” for fifteen months 1.

Appearance

• Height: 179 centimeters 1.
• Face and hair: Handsome, with long hair covering his forehead and temples and casting shadows over his eyes 24.
• Usual clothing: Black jacket, black jeans, black canvas shoes, and a black backpack 24.
• Bearing: Normally straight-backed; his subdued appearance gives him a gloomy air suited to a shadowed corner 24 37.

Personality

Qin’s ordinary demeanor is quiet and restrained. Officer Wang trusts him because years of observation found him harmless outside his criminal imitations, while Shangguan Xiaotao is drawn to his calm presence. His kindness is particularly visible around Rust City’s children: he brings them fruit and candy, accepts Little Ya’s handmade paper crane, and reassures her that he can now control himself better 10 11 35.

His Conscience-Free Syndrome allows him to imitate brutal killers without guilt or moral hesitation. He also uses detailed descriptions of murder methods to intimidate school bullies. This does not make him immune to every kind of distress: darkness and starlight trigger his other conditions, and memories of his parents provoke intense anger 3 10 17 23 36.

He is protective but guarded. He leaves Meng Jihe rather than expose the Geometry Design Group to the Research Society’s interest, and later withholds his ability details from his newly recruited underlings until they have earned greater trust 32 48.

Abilities & Skills

Consciousness Matrix

His Personal Brain identifies his ability as Consciousness Matrix, with separate entries for his brain conditions rather than the single Reality Enhancement category shown for Meng Jihe 28.

• Tracks each condition’s development independently 28 43.
• Distinguishes temporary development from development potential 28 43.
• Can produce exceptional combat effects even at zero Fusion Rate, without removing his difficulties with ordinary precision tasks 31 32 41.

Shadow Syndrome

Qin imitates criminals to reconstruct their behavior and methods. In the Experimental Zone, this also lets him physically reproduce techniques he had previously mastered only in theory 2 10 31.

• Criminal profiling: Imitates sixteen suspects and identifies the sixth as the missing girl’s killer 2.
• Forensic deduction: Predicts where the victim’s remains were distributed and directs police to test the painter’s cleanest glasses for concealed blood traces 2.
• Judo Fiend imitation: Performs throws, redirects falling momentum, and safely brings Rong Qian to the ground 31 32.
• The Concealer imitation: Contracts his shoulders and manipulates his joints while approaching a shoebox-sized ventilation opening 49.
• Limit: His judo technique cannot move Black Calamity, whose manifested body overwhelms him 38.

Conscience-Free Syndrome

Officer Wang describes this condition as a loss of personality that prevents guilt and moral apprehension, allowing Qin to recreate violent crimes without psychological distraction 3.

• Makes simulated killing no more morally burdensome to him than an ordinary activity 3.
• Develops temporarily during the lethal attack on Ke Qiming and again when he accepts membership in the Gang 31 43.
• Does not prevent condition-specific fear caused by Gestalt Collapse or Cosmic Phobia 17 36.

Gestalt Collapse

Diagnosed by Dr. House as level 16 Gestalt Collapse, this condition causes Qin to perceive terrifying forms in dim light. In the Experimental Zone, those perceptions can become physical monsters 17 18.

• Transforms crows into gigantic half-mechanical creatures; one reaches roughly fifty meters in size 18.
• Produces a monster strong enough to tear through and carry away part of the Iron Curtain 18.
• Responds to his shouted command in one encounter, causing a crow to attack the curtain 18.
• Is not reliably controlled: another transformed crow abducts Rong Qian 18.
• Initially carries a temporary-development reset condition tied to increasing his Fusion Rate 28.

Dissociation VI

Qin’s personalities can manifest as separate bodies in the Experimental Zone, matching Dr. House’s explanation of how dissociation might behave there 22 38.

• Black Calamity: His hostile dark personality, responsible for his adoptive parents’ deaths and repeated nighttime death traps 13 38.
• Armored protector: Emerges to defend him, destroys a monstrous attack, and creates two enclosing shields that withstand beam weapons, plasma weapons, and antimatter bombardment 38 39.
• Fourth personality: Dr. House’s case notes record that this personality likes candy; its identity and abilities are not disclosed 22.
• Limit: Black Calamity acts independently and seeks to kill Qin so that he can remain in the Metaverse as a separate person 38.

Cosmic Phobia

Looking into deep space or at stars in the night sky triggers uncontrollable terror 36.

• Qin manages the symptoms by avoiding looking upward after dark 36.
• No special Experimental Zone effect has manifested in the supplied chapters; its recorded development remains zero 36 43.

Equipment-Free Experimental Zone Access

Qin enters the Experimental Zone through sleep rather than a nutrient pod, initially mistaking the experience for a lucid dream 14 15.

• Jiu Zhengxuan’s recognition confirms that the encounter was real rather than merely a dream 24.
• Qin later explicitly concludes that he can log in without equipment 34.

Robot Visibility Anomaly

Central District guard and caretaker robots cannot visually perceive Qin, despite detecting biological signals and sound 6 7.

• Lets him walk past automated guards and enter a luxurious residence to take food 6 7.
• Is not universal invisibility: Officer Wang can see and block him while operating a Mechanical Proxy 12.
• Its cause is not explained in the supplied material 6.

Familiar-Territory Cognition

Dr. House and You Minglan add a condition to Qin’s case file that increases his brainpower in familiar territory. No name or further application is provided 22.
