Mechanics

Activation and Participation

• Linked side quests: A side quest can lead into the Main Quest. Xu Xin’s stolen-property quest carries an 80% chance of binding its participant to the Apartment’s Main Quest 37.
• NPC triggers: Some Main Quests require interaction with a specific NPC. The Undead Hospital’s quest becomes available when the missing Eerie Dean reappears 108 109 110.
• Immediate activation: Nightmare Fall Eerie Town begins with a Main Quest chapter titled “Chosen One,” rather than requiring Ji Yan to reach it through preliminary stages 437.
• Branching objectives: Faction choices can change both the Main Quest and the Dungeon’s final storyline, as with the Red and Black Emperor factions 266.
• Daily-quest replacement: In the Undead Hospital, participating in the main storyline automatically cancels daily quests 109.

Rules, Risks, and Hidden Routes

• Clearance: Completing the Apartment’s Main Quest allows a player to clear the entire Dungeon directly 16.
• Quest-specific failure conditions: The Apartment Thief quest announces no penalty for failure, but supporting the Red King binds followers’ lives to the King’s survival 37 266.
• Protected NPCs: Attacking an apparently hostile entity can still violate quest rules. Players who harm the protected Multi-faced Eerie receive penalties after the Apartment quest ends 50.
• Changed combat permissions: During the Hospital’s Main Quest, Player Ma explains that player killings can be classified as surgical accidents rather than rule violations 118.
• Hidden completion routes: Awakening the Old Landlord provides an Easter egg solution to the Apartment crisis. Blood Gu Eerie enables a third school questline beyond the two advertised factions 49 50 300.
• Order versus authority: Ordinary privileges cannot override a quest rule protecting an NPC from death. Authority can cause permanent effects that Order must accommodate by changing the storyline or settings 958.

Evaluation and Rewards

• Performance-based rewards: The Apartment quest evaluates discoveries and actions separately, then distributes rewards according to each player’s score 50.
• Persistent Dungeon access: The Apartment Door Key allows passage to the next Dungeon while marking the cleared Apartment as a save point 50.
• Retained progress: The Apartment stronghold mark preserves strategy progress and tenant favorability; one mark provides one Death Save back to the Apartment 37.
• Sequence development: In Eerie Town, Main Quest progress controls access to new regions, stronger sequence privileges, and additional Eerie Skills 508 533 559 609.

Crimson Apartment: Apartment Thief

Objective and Investigation

The S-rank Apartment Thief quest begins after a thief removes two children from the walls of Room 801. Its advertised perfect-clear objective is to capture the thief and recover the tenants’ lost property. Ji Yan participates independently, while Liu Yitong joins Long Yuan’s larger group 37.

Development	Chapter	Significance
Main-story connection revealed	16	Grandmother’s A-rank sachet delivery involves a Main Story Character and warns of uncontrollable danger.
Apartment Thief activated	37	Offers an Apartment stronghold mark and Door Key for perfect completion.
Apartment begins collapsing	42	A warning reports 13% damage attributed to the Main Quest boss.
Forbidden Basement discovered	46	Imprisoned tenants claim that the basement’s culprit is destroying the foundation.
Hidden Landlord route activated	49	Ji Yan opens the black coffin, exposes the tenants’ deception, and recruits the Old Landlord’s assistance.
Quest officially completed	50	The culprit is eliminated and the Game confirms that the Dungeon crisis has been resolved.

The imprisoned tenants are the actual saboteurs. The black parasites emerging from the coffin are attempting to repair the Apartment’s foundation, not destroy it. Once awakened, the Old Landlord kills the responsible tenants and seals their heads inside the coffin 49.

Performance Ratings

Ji Yan’s Results

• Highest score: 95 points 50.
• Reward package: Apartment Door Key and a Repair Gem capable of repairing Eerie items below Legendary quality 50.
• System improvements: Expanded Tool Bar, upgraded Information Panel, and more comprehensive game analysis 50.
• Personal gains: 300 Eerie Power and increases to every status attribute 50.
• Talent completion: The final Talent Fragment changes Omniscient Understanding from touch activation to gaze activation, costing 100 mental-state points per use 50.
• Apartment standing: His strategy progress rises above Long Yuan’s into first place, and every Eerie tenant’s favorability increases by more than 40% 50.

Penalties

• Players who attack the Multi-faced Eerie, a protected “kind NPC,” are punished according to the harm they cause 50.
• The player who delivers its killing blow receives permanent imprisonment in the Basement 50.
• Long Yuan and Huang Ran still receive rewards, but their rewards are substantially reduced 50.

Undead Hospital: Creation Tree

Access and Objective

• Trigger: The Eerie Dean’s reappearance restores the missing Main Quest prompt 109.
• Research premise: The Dean describes the Creation Tree as a way to give healed patients a paradise rather than return them to the dangerous outside world 110.
• Assigned objective: Enter Ward C001 and successfully treat its patient 110.
• Core reward: The Key to the Hospital Gate, which clears the Dungeon and saves progress 110.

Quest Developments

Dragon Player deliberately stalls the Main Quest while pursuing the Dean’s position. By the time Tiger Player explains the situation to Ji Yan, Dragon has advanced the quest halfway and holds 30% conquest progress against the Dean boss 108.

Ward C001 is a prison populated by people confessing and repenting. Player Ma warns that the designated patient is covered in lightning and dangerous to approach. Ji Yan remains skeptical of the Dean’s stated research purpose because Ma claims the healed patients are treated as livestock for slaughter 110.

• Ji Yan and Player Ma complete the C001 quest stage and seek the Dean to continue the main storyline 118.
• The supplied account does not establish the final outcome of the Hospital’s entire Main Quest 118.

School Dungeon: Faith and Principal Succession

Key Class Stage

Stage	Chapter	Requirement
Key Class Main Quest refreshed	215	Uphold “Faith” to the end and receive “Its” response.
Experimental Class entry	266	Choose a faction after receiving invitations from the Red King and Black King.
Hidden third Main Quest opened	300	Use Blood Gu Eerie to replace the advertised Red-versus-Black resolution.

Advertised Faction Routes

Faction	Completion Condition	Ji Yan’s Position
Black Emperor Faction	The Black King overthrows the Red Emperor Faction and becomes Eerie Principal 266.	Rejects the invitation 266.
Red Emperor Faction	The Red King annihilates the Black Emperor Faction and secures the principal’s position 266.	Enters Experimental Class 1 under the Red King 266.

The Failing Red Route

• Survival dependency: The Red King warns that its death will kill Ji Yan and all its followers 266.
• Hell-tier difficulty: Qiu Tong describes the Red faction’s Main Quest as nearly ruined 267.
• Judging system: Players must persuade three Eerie Judges to vote for their candidate. Two favor the Black King, while the last remains neutral 267.
• Deadline: Three days remain when Qiu Tong explains the situation 267.
• Failure evidence: Statues in the New Campus are former Experimental Class players who died during side quests or failed the Main Quest 267.

The Red King’s disappearance stalls its questline and disrupts the defection system. Qiu Tong, Guo Cheng, and Li Yixian switch to the Black faction while retaining their original King-card privileges alongside Black King Jack-card buffs 270.

Bai Liangshen later identifies his own defection as an exploitation of a Main Quest bug and the “transferring faith” reward. His actions ruin the original balance between the two faction storylines 279.

Hidden Third Route

• Principal’s Office key: A hidden compartment in The Miracle of Life provides a key recognized by the Game Panel as a hidden Main Quest reward 273.
• Dual-Path Secret Notes: Ji Yan triggers a hidden Red King storyline through Blood Gu Eerie and receives the final judge’s location plus a secret concerning principal succession 282.
• Judge location: The final Eerie Judge is inside an otherworld contained in a library book 282.
• Third objective: Rather than complete either advertised faction route, Ji Yan opens a Hidden Main Quest in which Blood Gu Eerie devours the Red King and becomes Eerie Principal 300.
• Late-stage status: By the Dungeon epilogue, Ji Yan considers the third route a sure thing and avoids risking a confrontation that could disrupt clearance 302.

Nightmare Fall Eerie Town: Sequence Main Quests

Shared Framework

Eerie Town contains 32 sequence storylines, each associated with an Extreme Fiend whose scattered remains must be recovered. Ji Yan unlocks the thirty-second storyline, associated with the Eerie Game Master 441.

• Core objective: Collect every piece of the chosen Extreme Fiend’s Old Bones and revive it to clear the instance 441.
• Bone privileges: Individual Old Bones contain different Order privileges that players can borrow 441.
• Competing objectives: Followers of different Extreme Fiends may come into conflict because their main storylines differ 441.
• Alternative acquisition: Trials are not the only way to obtain Old Bones; roaming NPCs and hidden areas also provide opportunities 509.

Documented Progress Milestones

Stage / Progress	Chapter	Notes
35% — Elite Disciple access	508	Ji Yan deceives three sequences and performs a “foolish play,” unlocking South Town. West Town’s main trials close.
50% threshold — Godly Zone access	533	Unlocks East Town. The fourth impersonation identity is Space Traveler.
Above 70% — Skeletal Soul activation	559	Normally activates the Extreme Fiend Skeletal Soul and further sequence-privilege use.
Additional 10% progress	597	Ji Yan’s praise of the Eerie Lord of Deception receives a response and a progress increase.
90% threshold — Advanced Eerie Skill	609	An Eerie Skill normally requires this progress level; Ji Yan asks his Sequence Lord to grant it early by deceiving Order.

Sequence-Specific Conditions

• Eerie Game Master: Advances through impersonating other sequences during trials without being discovered 469.
• Memory-tape objective: One other disciple’s sequence requires at least 25 sequence memory tapes for a perfect clearance score of 90 or higher 469.
• Progress regression: A Black Death Sword disciple killing a Siren Seductress disciple causes the killer’s Main Quest progress to regress 464.
• Siren Seductress duration threshold: Its temporary peak-condition restoration becomes unlimited only after Main Quest progress exceeds 60% 472.
• Hidden allegiance change: Xu Xin tells Ji Yan that abandoning one Extreme Fiend for another is a hidden setting, warning that the Eerie Game Master sequence is a dead end in East Town 553.
• Artificial advancement: The Eerie Lord of Deception can falsify progress and survival time to bypass normal regional-access requirements 559 609.

Black and White Chess Questlines

Opposing Goals

Side	Main Quest Role
Black Chess	Cause Order Dungeons to collapse 650.
White Chess	Perfect Order Dungeons 650 701.

At the Chess Player level, players can travel to Dungeons below Tier 8 and portray NPCs. They advance their own Main Quests by selecting promising players as pawns and using those pawns to influence Dungeon outcomes 610.

Manipulated Dungeon Quests

• 444 Asylum: Its apparent Main Quest instance is fabricated using Anthropomorphic Ghouls and spliced game panels to mislead Ji Yan 694.
• Emergency Main Quest: L uses it to examine a selected player’s potential, alongside a Battle Royale side quest and a plan to perfect the Dungeon 701.
• Grave Mound Ghoul Prison: A White Chess Player conceals the Main Quest involving 2,000 copper coins 759.
• Perfect-clear route: Returning those coins to their original location would lure out Ksitigarbha Bodhisattva, level the Haunted Houses, and produce a 20.0 Perfect Dungeon clearance 759.
• Black Chess alternative: Ji Yan seeks the same coins to cause Deterioration rather than complete the White side’s perfection plan 759.

Lush City: Demon Card

Opposed Objectives

Participant	Objective
Challenger Players	Seize the Demon Card and prevent Phone Eerie from taking control of Lush City 965 980.
Phone Eerie	Use the Demon Card to fully control the city, lift its dismemberment restriction, and reassemble its separated bodies 965.

Phone Eerie is a Tier 12 Main Quest boss split by Order into seven remnant bodies. Its core remnant controls the Demon Card, while recovered remnants provide important quest information through the Game Panel 965.

Stakes and Rules

• Citywide threat: The Demon Card magnifies citizens’ desires and drives increasingly destructive behavior. Leaving the Main Quest uncleared for too long causes the city to fall under its control 964 965.
• Temporary refuges: Player-controlled side quests initially shelter ordinary people, but Li Xiao warns that these refuges will not remain safe after the city falls 965.
• Remnant containment: Gold can seal Phone Eerie’s remnants; formatting a containing phone reveals Main Quest information without erasing the remnant itself 965 966.
• Route clue: A recovered coordinate directs the group to Tianfangye Group at midnight 966.
• Boss location restriction: The Demon Card can operate only within Tianfangye Group, a five-star-difficulty side quest 980.
• 48-hour deadline: If Challenger Players fail to plunder the card, Phone Eerie may activate Desire Frenzy, subject the city’s humans to an “eerie baptism,” and gain citywide control 980.

Documented Challenger Blessings

Blessing	Effect
Purification USB Drive	Formats and seals Phone Eerie’s core remnant 980.
Immunity Holy Body	Lets attacked Challenger Players temporarily disable two Phone Eerie remnants 980.

Completion

Ji Yan proposes dividing the team: he and Li Qingzhi enter Tianfangye Group, while Wang Sihan and Li Xiao defend Caesar Hotel and the Temple of the Dead Buddha to preserve an escape route 981 982.

After defeating Phone Eerie’s puppet Fang Yao with Blood Shadow Wedding Dress, Ji Yan uses the Purification USB Drive and obtains the Demon Card. He completes the Challenger Player Main Quest and earns qualification to proceed to the Elysian Shore 1006.

Grotesque Town: Changing Main Storyline Clues

• A Main Quest clue is revoked and replaced with a 30-minute countdown 1069.
• Ji Yan, Kong Yi, and Doctor Long burn the Devil attendant’s corpse, uncovering hidden information about the Fool’s attendant 1069.
• A new clue involving ravens follows; the chapter identifies the Fool as manipulating the main storyline and the players pursuing it 1069.

Time Dungeon: Nan’guang Mahjong

Activation and Previous Failure

• Gate access: Tianma explains that entering a Gate is necessary to activate the Main Quest, while Time Eerie attempts to prevent entry 1170.
• Main-story enemies: Red Center Masks identify main-story NPCs responsible for targeting participating players. When the storyline is dormant, they gain greater authority to interfere with side-quest Gates 1170.
• Failure consequence: Caesar is found merged with the Spectral Tour Train after failing the Main Quest 1214.
• Restart: A Whiteboard Mask opens the Door leading to the rule-announcement chamber. It warns that activation is irreversible and that the new attempt will be more cruel 1222.
• Rule administrator: A mysterious projected woman announces the rules and activates Main Quest Order. Her presence forcibly disables Ji Yan’s Omniscient Understanding and its associated Dungeon interface 1222.

Winning-Hand Rules

Mechanic	Function
Core objective	Assemble a Winning Hand in Nan’guang Mahjong to clear the stage 1223.
Card Seizure	Converts Doors and Eerie masks into usable mahjong tiles 1223.
Door tiles	Obtained by clearing the associated Dungeons with perfect ratings 1223.

Current Attempt

The group begins with Eight Bamboo, Nine Stripes, Nine of Dots, and Eight of Characters. They submit these initial tiles and receive the Ring of Privilege 1223.

• Jiu Ye and Kong Yi: Seek the Seven of Dots tile through a Door Jiu Ye has previously explored 1223.
• Tianma and Ji Yan: Search for Catherine, whose Authority corresponds to Nine Myriad; locating her may provide either a tile or another ally 1223.
• Previous target: An earlier attempt pursued Big Three Dragons, requiring masks from nine Eeries. The attempt broke down at the final Red Center Mask when Future Ji Yan refused to continue 1223.
• Unresolved signal: The projected woman watches Ji Yan and writes a character he tentatively identifies as “Xun” 1223.
