Background / History

Yu Qing is an orphan. Before entering the game, he worked as a programmer; his available memories also include reports of people disappearing after boarding mysterious buses. He recalls having been forced onto a bus himself, but the circumstances behind his selection are not explained 1 3 43.

His beginner trial places him in a seemingly comfortable home with creatures posing as his parents. Their claim that it is lunchtime despite his watch reading midnight, their unnatural movements, and the interrupted emergency broadcast expose the household’s danger. Yu Qing hides an object in his coat and approaches them while pretending to seek comfort 1.

Strawberry candy later awakens a vague, painful memory of someone who once gave him the same kind of sweet. He cannot clearly identify that person in the supplied chapters 25.

Appearance

• Build: Slender, with pale skin and an innocent-looking face that helps make his smiles and reassurances convincing 3 20 22.
• Hair: Waist-length white hair, also described as silver; he sometimes ties it back with an elastic or a blue hair tie patterned in black 3 19 24 45.
• Eyes: Turn vivid crimson when he kills Granny Ghost; Qian Lai later sees scarlet eyes in the darkness 9 43.
• Earring: Wears an earring in his left ear whose power interests the BOSS 18.
• Supernatural marks: Receives a black Red Spider Lily on the back of his hand and, later, half of a red spider lily carved into the back of his neck 36 49.
• Notable clothing: Uses white coats and Xu Han’s badge as disguises; also wears the BOSS’s oversized black coat and a shop-bought, medieval European-style white outfit 23 31 36 38.

Personality

Yu Qing’s composure is often a performance rather than an absence of fear. He experiences cold sweats, trembling, nausea, and exhaustion, but deliberately controls his expression and voice. When appealing to a female ghost, he lets his hands shake so that he can keep speaking steadily 3 7 22 37.

He is observant, economical, and quick to improvise. He studies maps, tests rules, and searches for inexpensive alternatives to the system shop’s promoted items. His polite manner also masks a vindictive streak: after the system nearly suffocates him, he destroys it; after the Doctor attacks him, he secretly disables the Doctor’s protective bell 5 10 16 26.

His ruthlessness coexists with concrete acts of compassion. He spends 30,000 points on medicine for the injured nurse, comforts Tangtang, helps abused ghosts retaliate, and bows to the director’s mother as her ghost fades. He also lends Zhang Yi a protective disguise, although doing so changes Xu Han’s hunting target 14 20 23 28 29 48.

Yu Qing refuses to equate possession or forced intimacy with love. He acknowledges the coercion in his own use of supernatural items while condemning the BOSS’s attempts to manufacture closeness. By the final supplied chapter, he is determined both to escape and to become the top-ranked streamer, without letting Qian Lai die beside him 35 45 50.

Abilities & Skills

Observation and Deduction

• Detects the false household through conflicting time information and the impostors’ behavior 1.
• Uses the Sanatorium floor plan to recognize mezzanines and locate a safe area 5.
• Reconstructs the patients’ conditioning, mutilation, and conversion into zodiac sacrifices from their diaries 27 29.
• Identifies the Sanatorium as Xu Han’s dream by connecting its distortions to his memories and observing dark-purple space beyond its walls 40 41.
• Discovers that the Dream Core is corrupted and that the director has taken control of the dream 43 44.

Deception and Psychological Manipulation

• Feigns distress to draw the false parents’ attention, muteness to avoid registration, and blindness to approach the director 1 14 31.
• Uses affection and kisses to distract the BOSS, loosen its restraints, deliver a potion, or conceal a controlling incantation 11 18 33 45.
• Exploits a ghost’s grief for her younger brother by addressing her as “big sister” and offering help against the Doctor 22.
• Frightens the director with an alarm clock presented as a bomb 44.
• Stages surrender to the BOSS after realizing where the escape key must be 50.

Livestream and System Use

• Cultivates viewer engagement and tips by alternating vulnerability, flattery, and dramatic reversals 6 7 9.
• Attempts to use audience requests as permission to harm NPCs; the system rejects that interpretation and sentences him to erasure 9.
• Links with other streamers’ systems to inspect information, including Qian Lai’s luck stat of 103 25 28.
• Uses accumulated points to restore HP during otherwise lethal attacks; this does not prevent exhaustion or replenish his naturally low stamina 5 24.
• Exploits system targeting by entering TTS1888 as a Demolition Card’s target, then later uses the threat of another purchase to secure livestream privacy 10 34.

Combat and Improvised Tactics

• Kills the masked clown through darkness, rearranged furniture, and a bathroom-doorway trap rather than a direct contest of strength 3.
• Overpowers Granny Ghost and kills her with the Golden Needle 7 9.
• Secretly removes the Doctor’s bell clapper during physical contact and hides it in system storage 16.
• Uses the Sanatorium’s clothing-and-badge identity rules to obtain staff authority and turn the Doctor’s position against him 22 23 27.
• Remains vulnerable to stronger enemies: the BOSS repeatedly restrains and disarms him, while depleted stamina leaves him unable to pry Xu Han’s hands from his throat 22 32 39.

Unexplained Supernatural Traits

• Internal weapon concealment: Draws the Golden Needle from inside his arm. Its emergence leaves his skin uninjured; the mechanism is not explained 20.
• Vision in darkness: Can see after the bathroom lights go out and later uses his red eyes to locate his own blood on the Sanatorium’s outer wall 38 44.
• Controlling incantation: Places a heart-shaped mark on the BOSS and commands its tentacles. Viewers recognize a technique associated with the Puppeteer, but Yu Qing’s knowledge of it remains unexplained 45.
• Earring power: Claims that the earring’s power has fused with him while bargaining with the BOSS; the supplied context does not establish its full effects 18 19.

Equipment / Weapons / Items

• Golden Needle — Approximately forty centimeters long. Concealed inside his body; used to kill Granny Ghost, sabotage the Doctor’s bell, fight skeleton orderlies, and wound the BOSS. It can still be taken from him 9 16 20 22 33.
• “I’ll Cut You Down” — Rare, roughly forty-centimeter double-edged blade obtained by destroying a system. Analyzes severed material, but cannot determine the black mist’s origin 10 11 13.
• Left-ear earring — Contains power sought by the BOSS, which attempts to pull it from his ear 18.
• Golden wrist bell — Issued as protection against ghosts. Also helps him win Tangtang’s trust; he later removes it deliberately to lure Xu Han 14 20 30.
• Xu Han’s name badge and white coat — Let him pass as staff under the Sanatorium’s identity rules. He temporarily gives them to Zhang Yi and later recovers them 23 27 28 30.
• Obedience Potion — Costs three million points; one drop grants one minute of obedience and can be used only once per day. Yu Qing uses it on the BOSS’s tentacles 23.
• Dizzy Water — Intended to put a BOSS to sleep for a day. He drinks it and transfers it through a kiss, but suffers a potent aphrodisiac effect as a streamer 33 34.
• Suppression Chain and Control Ring — Purchased at the cost of nearly all his remaining points to restrain the BOSS. The BOSS later steals the ring and reverses their positions 34 35.
• Revival Card — Saves him from the system’s suffocation punishment, although delayed loading nearly kills him 9 10.
• Demolition Card — Costs nine million points and destroys a named target. Used against system TTS1888 10.
• Metal-Melting Water — Inexpensive lock-dissolving item used instead of buying a costly master key 25 26 48.
• Access cards — Takes an entire box from the Director’s Office. A working card opens only the inner wooden exit door; the outer iron door still needs a key 31 32 40.
• Ring-bearing severed finger — Retrieved from Granny Ghost’s abdomen; the wedding ring is engraved “XH” 10.
• Severed BOSS tentacle — Cuts it off and stores it as a keepsake after placing the BOSS under his controlling mark 45 46.

Marks Imposed by the BOSS

Mark	Effect / Condition
Temporary black Red Spider Lily	Appears after Yu Qing receives ten drops of the BOSS’s blood. Permits control of his actions for half a month; he also displays it to frighten attacking NPCs. It disappears during one encounter but is shown again afterward 35 36 38 39.
Half-carved red spider lily	Carved into the back of his neck and does not heal. Completion would require him to drink the BOSS’s blood every two weeks or risk mental collapse and death. The BOSS promises to remove the unfinished mark if Yu Qing finds the key 49 50.

Relationships

• Qian Lai — Roommate and principal ally. Yu Qing judges him trustworthy, shares deductions with him, and relies on his talismans and physical assistance. Qian Lai later summons the Dungeon’s corpses to search for him; Yu Qing refuses to let him die with him 17 25 43 50.
• Black-mist BOSS — Level-seven adversary with a possessive fixation on Yu Qing. Yu Qing calls him “husband,” “baby,” and “Master,” often strategically; their encounters alternate between coercion, care, flirtation, and attempts to control or kill one another. No actual marriage is established 13 19 24 35 45 49.
• Xu Tang / Tangtang — Xu Han’s daughter, transformed into the zodiac rabbit. Initially accepts Yu Qing as her father when he uses the bell, then attacks him after recognizing the imposture during his diary search 20 26.
• Receptionist nurse — Xu Han’s wife and a victim of the fake Xu Han and director. Yu Qing gives her healing medicine and later removes his disguise to reassure her, earning enough trust for her to begin explaining her past 14 31.
• Xu Han — Dead father, hidden NPC, and presumed ritual priest. Hunts Yu Qing as an impostor; Yu Qing tries to redirect his anger by revealing what happened to his wife and daughter 26 30 39 41.
• Female ghosts — Abuse victims whom Yu Qing addresses as “big sisters.” He helps them overthrow the Doctor, and they subsequently guard him and answer his calls for help. Some later attack during Xu Han’s escalation 22 23 25 29 39.
• The Doctor / fake Xu Han — Enemy who killed and impersonated the real Xu Han. Yu Qing disables his bell, takes his disguise, cripples him, and delivers him to the ghosts for revenge 16 21 23.
• The director — Principal institutional antagonist. Yu Qing exploits his reliance on badges, steals his access cards, exposes his control of Xu Han’s dream, and uncovers his mother’s imprisonment in the Angel Statue 27 31 44 46.
• Xue Ziyi — Rival streamer displaced by Yu Qing on the Newcomer Rich List. Becomes largely compliant after Zhang Yi’s death and joins an unsuccessful escape attempt 28 32.
• Zhang Yi — Aggressive follower of Xue Ziyi. Yu Qing lends him the staff disguise despite his threats; the transfer changes Xu Han’s target, and Zhang Yi later dies 28 29 30.
• Livestream audience — Source of points, scrutiny, and conditional support. A ten-million-point donation funds Yu Qing’s survival, but viewers also demand performances, encourage danger, and repeatedly misread his strategies 6 9 10 50.
• Little shadow man — Emerges from the BOSS’s heart wound and comforts Yu Qing while he is incapacitated by Dizzy Water. Yu Qing later assumes the encounter was a hallucination 34.

91%	Identifies the director’s mother as the woman sealed in the Angel Statue 46.
99%	Reads the mother’s account and reconstructs the director’s history; the escape key remains missing 48.

Dream Core and the Escape Key

• Determines that the access card is insufficient: the exit has an outer iron door requiring a separate key 40.
• Connects the dream’s horrors to Xu Han’s experiences, then enters the dark-purple space beyond the Sanatorium to seek its Dream Core 41 42.
• Finds the core corrupted and its key missing; escapes with Qian Lai by following a blood marker left on the building 43 44.

Contest with the BOSS

• Receives the epic hidden quest “Play games with the BOSS,” whose rules are set by the BOSS 19.
• Repeatedly reverses captivity through concealed weapons, potions, restraints, and psychological tactics, but becomes subject to the BOSS’s temporary control mark 23 33 34 36.
• Refuses the BOSS’s invitation to stay and secretly marks him in return, gaining enough control to bind him and sever a tentacle 45 46.
• Is later threatened with a permanent blood-dependent binding. The BOSS leaves the neck mark unfinished and makes its removal conditional on finding the escape key 49 50.
• With only two hours remaining, finds the director inside the coffin beneath the Angel Statue but no key on him. Yu Qing then realizes where the key must be and stages surrender to lure the BOSS back; the supplied chapters end before the plan’s outcome 50.
