Chapter Summaries

Lin Ye examined his new doomsday shelter and discovered that his talent let him simulate a Class-D personnel on a mission. He entered a simulation as Kenneth and watched the first prisoner get sent into a villa, while the remaining simulations were limited to ten.

• Lin Ye checked his system, learned his shelter was safe for seven days, and found that his Class-D Personnel Simulator could run one mission simulation each day.
• He inspected his shelter and beginner pack, found no working water, gas, or electricity, and chose not to risk entering the dangerous fog outside.
• Lin Ye activated his talent and woke in a transport vehicle as Kenneth, a Class-D prisoner with ten simulations remaining.
• A fellow prisoner told Lin Ye that the armed Supervisory Personnel did not know what awaited them in the villa and were using the prisoners to scout it.
• At the villa, the team captain sent the first Class-D prisoner inside wearing a camera helmet, then called for Number two five minutes later.

Lin Ye repeatedly died while investigating a villa and used his simulations to learn which dangers to avoid. After reaching the second floor, he resisted the Captain’s order to open a strange black box, but closing it drained his life and killed him.

• Lin Ye entered the villa with a dagger, found a Class-D Personnel member disassembled in a corridor, and died when something attacked him from behind.
• Lin Ye woke with eight simulations remaining and decided to avoid the first floor by heading upstairs.
• Lin Ye reached the second-floor living room and found a partly opened black box.
• The Captain urged Lin Ye to open the box, but Lin Ye saw the Captain and three team members impaled outside the windows and tried to close it instead.
• The box drained Lin Ye’s life before he lost consciousness, and he woke again with seven simulations remaining.

Lin Ye closed the Abyss Box in the simulation, saving the area and earning a reward that included one use of the real box. He opened it in the Shelter, where the system neutralized its dangers and let him choose from the bizarre objects that spilled out.

• Lin Ye entered the villa first and died when a red-eyed figure transformed his body, then concluded that the first person inside was certain to die.
• Lin Ye entered after Number One, rushed upstairs, and closed the Abyss Box despite the Captain's warning and the presence approaching behind him.
• The simulation ended, awarding Lin Ye six items, Abyss Box use authorization, and the title Savior.
• Lin Ye found an orange specimen of a reassembled human body among his rewards and read that the Savior title improved his treatment as Class-D Personnel.
• Lin Ye used the authorization to open the Abyss Box in the Shelter, and the system rendered its dangerous contents harmless before he could choose an item.

Lin Ye chose a card box as his Abyss Relic and discovered that its first card summoned a goose that could provide one serving of goose-leg rice. He joined the nighttime Maze Exploration and began searching its rooms for treasure, finding a strange metal coin as the activity began.

• Lin Ye selected a red card box, and the system rendered it harmless and gave it to him as an Abyss Relic.
• Lin Ye drew a card that summoned a blood-red goose, which produced one bowl of goose-leg rice and could do nothing else.
• Lin Ye posted a photo of the rice in the group chat, surprising hungry survivors and explaining that his talent had given it to him.
• Lin Ye decided to join the nighttime Maze Exploration and prepared his weapons and equipment before the countdown ended.
• Lin Ye arrived in a dark red corridor, learned that participants' first treasure chest would contain a Shelter Upgrade Blueprint, and entered an empty room.
• Lin Ye collected some written scraps and found a dark red metal coin bearing a blood-red eye.

Lin Ye explored the maze, found supplies in a locked storeroom, and killed a Blood Corpse that attacked him in the corridor. He later discovered a red chest in another locked room and cautiously opened it, but the chapter ended before he saw what was inside.

• Lin Ye found a locked storeroom and used a Red Key to enter, collecting two bottles of red liquid, a metal pendant, and seven patterned cards.
• A Blood Corpse approached the storeroom, and Lin Ye shot it repeatedly before dodging its attack and killing it with gunfire.
• Lin Ye dissected the corpse, found five Red Keys on a key ring, and decided to focus on locked rooms rather than ordinary ones.
• Lin Ye entered another locked room and found an unlocked red wooden chest at its center.
• Lin Ye lifted the chest lid with his dagger and retreated, but nothing dangerous emerged.

Lin Ye explored the Red Maze, found supplies and a special room, and learned that Mutation Organs could be used to upgrade his Shelter. After returning, he shared what he had learned about Mutated Creatures with the group, leaving survivors to prepare for future encounters.

• Lin Ye used a Mutation Organ from a Blood Corpse to start his Shelter upgrade task, which required ten organs, then continued searching locked rooms for supplies.
• Lin Ye found bread and water in a Redwood Chest, then reached a special room and collected a bottle containing red liquid and an eyeball.
• With the exploration countdown nearly over, Lin Ye found another Redwood Chest containing red liquid, rigid cards, and a different red metal key, then returned to his Shelter when time ran out.
• More than two thousand people had died during the exploration, and survivors flooded the group chat with messages about chests, blueprints, and Mutation Organs.
• Lin Ye posted a picture of the Mutation Organ and shared his cautious theory that they were weak points of Mutated Creatures, while explaining that his handgun came from trading through his talent.

Lin Ye traded maze items, rejected the Mutual Aid Association’s offer to recruit him, and drew a blood-red cat that granted him an operation-specific item ability. He began another simulation as Larry with an Abyssal Egg in his pocket, arriving with his team at a tunnel entrance.

• Lin Ye blocked people who complained about his food trades and exchanged bread and water for valuable chest items, including a mutated weapon blueprint from Zhang Liang.
• Zhang Liang invited Lin Ye to join the Mutual Aid Association, but Lin Ye refused and questioned the group’s plan to profit from the information he shared.
• Zhang Liang told President Wu Ming that Lin Ye had refused; Wu Ming chose not to smear him and learned that most explorers sent outside had died quickly.
• Lin Ye drew a blood-red cat, which gave him the ability to draw an item before each operation, usable only until that operation ended.
• Lin Ye used his daily ability to simulate Class-D personnel Larry and received an Abyssal Egg before the prison transport stopped near a tunnel.

Lin Ye entered a mysterious tunnel where the lights went dark and a hulking monster appeared and vanished, then encountered Jesse, who claimed he had been walking for almost three hours. As they agreed to turn back, Lin Ye questioned how Jesse could have been ahead of him in a tunnel with no forks.

• Lin Ye entered the tunnel with a dagger and walked for half an hour without encountering anything.
• The lights went out, and when they came back on, Lin Ye saw a hulking monster that vanished after the darkness returned.
• Lin Ye continued forward, making wishes as he walked, but the tunnel remained empty until the lights went out again.
• Lin Ye encountered Jesse, who believed Lin Ye had turned back and asked whether something lay ahead.
• Lin Ye and Jesse agreed to head back together, and Jesse said he had been walking for almost three hours.

Lin Ye discovered that the tunnel’s apparent time loop was connected to his transformation into a monster and that he was encountering versions of himself from later loops. He killed the next version of himself to trigger another simulation, then recognized the marks on its body as three Möbius strips.

• Lin Ye found the tunnel still had no exit and encountered Reynold, who said he had been trapped for hours and could not find his way out.
• After another blackout, Lin Ye saw a version of himself flee and realized he had become the monster he had seen earlier, apparently because of the Abyssal Egg.
• Lin Ye decided to solve the tunnel anomaly himself rather than risk reporting it to the organization or captain.
• A larger, more mutated version of Lin Ye appeared and wrote that this was the last chance to kill him before the simulations ended.
• Lin Ye killed the other monster and noticed three intersecting marks on its body, recognizing them as Möbius strips.

Lin Ye reasoned through the Möbius Strip time loop and studied how the Abyssal Egg changed his body, eventually reaching the predetermined encounter with himself. He awoke in the prison transport with nine simulations remaining and recognized that simulations let him study mutation and gain experience from Anomalous Events.

• Lin Ye concluded that the three Class-D Personnel were trapped in intersecting time loops and feared the Abyssal Egg would mutate him until he could no longer control himself.
• Lin Ye discovered he could sense and influence his body’s mutation, and he began developing a powerful malformed heart as his vital point.
• Lin Ye encountered No. 2 and No. 3 again, then followed the predetermined script when he met himself from the previous loop.
• Lin Ye opened his chest but could not kill himself because the Abyssal Egg’s consciousness prevented him from doing so.
• Lin Ye awoke in the prison transport with nine simulations remaining and realized his ability was useful for studying mutation and gaining experience from Anomalous Events.

Lin Ye tried to study the Abyss and end the simulation loop, but the Abyss Consciousness overcame his other self and pulled him into the Abyss. He woke in another simulation with a plan to connect the Abyss to the tunnel and leave the rest to it.

• Lin Ye entered the tunnel carrying the Abyssal Egg and monitored his body as its influence began mutating him.
• He met his monstrous self, who warned that the Abyss Consciousness had trapped him and urged him to kill him.
• Lin Ye killed his monstrous self, then his heart mutated and revealed the vast Abyss to him.
• Lin Ye relived the conversation from the other side, realized how to leave the Abyss, and fell into it after killing himself.
• Lin Ye woke in a new simulation with eight simulations remaining and decided to connect the Abyss to the tunnel.

Lin Ye completed the tunnel ritual in the simulation and gained a Time Rule Fragment, a Gate to the Abyss, and a title that drew the attention of Abyss Dwellers. Back in the Shelter, he discovered a new ability to rewind time after death and learned that survivors were experimenting with Mutation Cards.

• Lin Ye raised the Abyssal Egg in the tunnel as matching eggs in other loops completed, connecting the tunnel to the Abyss and finishing his mission.
• The simulation ended with Lin Ye receiving eight random items, a Time Rule Fragment, the title Fall into the Abyss, and a Gate to the Abyss.
• Lin Ye submitted four Mutation Organs to the Shelter upgrade mission, raising its progress to 5/10, and incorporated the Time Rule Fragment into his innate ability.
• Lin Ye discovered that his ability now let him rewind time after death once, and he read that his title had attracted the attention of beings in the Abyss.
• Lin Ye avoided opening the Gate to the Abyss and read survivor messages about Mutation Cards, learning that mutations required large amounts of matter and energy and could be completed with red liquid.

Lin Ye explained the dangers of Mutation Cards to Zhang Liang, then entered the maze for the night’s activity. After receiving a Lucky Cat Tail Amulet and testing the Cross Necklace, he began hunting for Mutation Organs and killed a Blood Corpse with his dagger.

• Lin Ye traded his spare Mutation Cards and told Zhang Liang that using the cards could dangerously affect the body and mind, especially in the Red Maze.
• Zhang Liang reported Lin Ye’s information to Wu Ming, who decided to share details by rank and warned members not to use Mutation Cards yet.
• Lin Ye joined the nighttime maze exploration and received a Lucky Cat Tail Amulet that improved treasure chest contents.
• Lin Ye tried on the Cross Necklace, experienced a monster’s heightened senses, and quickly removed it because he feared side effects.
• Lin Ye found a locked Red Room, lured out a Blood Corpse, crippled its knee, and stabbed its mutated flank until it collapsed.

Lin Ye found a blood-red saber in a chest and later encountered a flesh-and-blood monster that chased him through the Red Maze. He killed it with his pistols by using the Cross Necklace to sense its weak points, but the necklace left him with severe pain and impaired vision.

• Lin Ye took a blood-red saber from a mahogany chest and tested its sharpness on the Blood Corpse.
• Lin Ye found a room covered in fused flesh, and its monster chased him through the corridor.
• Lin Ye put on the Cross Necklace and used its perception to identify the monster's strongest energy points.
• Lin Ye baited the monster around a corner and fired all ten pistol shots into it, bringing it down.
• Lin Ye waited until the monster was dead, then suffered darkened vision and stabbing brain pain until he removed the Cross Necklace.

Lin Ye explored a pale yellow shop room, sold two energy crystals, and bought a ring and Mutation Cards before the countdown returned him to the Shelter. He advanced the Shelter to Tier 1, unlocking utilities and basic item inspection, and learned more about the Mutation Cards he had collected.

• Lin Ye recovered from the Cross Necklace's aftereffects, dissected the monster, found six Mutation Organs and dark red energy crystals, and submitted four organs for his mission.
• Lin Ye explored a pale yellow shop room, sold two crystals for 25 Red Coins, and spent 70 Red Coins on a ring and three Mutation Cards.
• The countdown returned Lin Ye to the Shelter, where he accepted its advancement to Tier 1.
• Lin Ye discovered that the Shelter now had water, electricity, and gas, along with basic information inspection.
• Lin Ye used the new function to identify Nutrient Solution and Mutation Cards, and found that he had collected eight of the ten numbered cards.

Lin Ye traded for supplies and blueprints, then studied the Splicing Figure before drawing a radio card that began broadcasting a warning about the city’s mutated creatures. The broadcast said that after the Initial Stage ended, the strongest creatures would feast on the survivors.

• Lin Ye showed the chat group his upgraded Shelter’s hot shower and running water, then shared information about common items and Shelter functions.
• Lin Ye traded with survivors for supplies and obtained a Tier 1 Psionic Energy Crystal Maker Blueprint requiring ten Tier 1 Mutation Organs.
• Zhang Liang traded Mutation Card No. 3 to Lin Ye for a Mutation Organ and cards No. 7, 8, 9, and 10, asking Lin Ye to report what happened when he combined the set.
• Lin Ye poured hot water over the Abyssal Egg and studied the Splicing Figure mural’s arts of Cutting and Splicing.
• Lin Ye drew a Radio card, and the old-fashioned radio began playing a broadcast from Mr. X about mutated creatures occupying the city and planning to feast on survivors after the Initial Stage.

Lin Ye shared information from the Voice of the City broadcast, then began a simulation as D-class personnel Tris, sent with Hans and Neil to investigate a silent research institute. After surviving a strange elevator descent and entering the bloodstained facility, they reached its main hall.

• Lin Ye shared broadcast information in the group chat and waited for his lucky moment before continuing to study the mural.
• Lin Ye began a simulation as Tris and joined Hans, Neil, and guards on a mission to investigate a research institute that had lost contact with the organization.
• The captain gave the team pistols and ammunition, and shot D-class No. 3 dead after he protested; Lin Ye requested and received a prototype long blade.
• As the team descended underground, knocking surrounded the elevator, and Lin Ye explained how to identify Mutated Creatures' weak points.
• The elevator opened onto a bloodstained corridor with no bodies, and Lin Ye led the team through it to the laboratory's main hall.

Lin Ye and his companions found Dr. Caroline in the underground institute, but the Captain lost contact with them as mutated creatures approached. Caroline led the group through the ventilation system to a laboratory cell, where Lin Ye began killing the pursuing blood corpses.

• Lin Ye, Hans, and Neil reached the level-seven laboratory and found Dr. Caroline, who gave them research data and specimens.
• The Captain’s transmission failed, the lights went out, and a horde of mutated creatures approached the laboratory.
• Lin Ye forced Caroline to choose whether to help them escape, and she led the group through the ventilation system.
• Blood corpses pursued the group through the vents, and Lin Ye killed them with his pistols while they retreated.
• Caroline led them into a laboratory cell after their route was blocked, and Lin Ye fought the blood corpses that followed them.

Lin Ye and his companions survived the Blood Corpses’ attack while he pieced together that the institute’s escaped experiment was manipulating events to keep them underground. When a tremor gave them a chance to flee, a red-haired Caroline appeared and stopped Lin Ye’s bullets in midair.

• Lin Ye conserved ammunition by switching to his blade, and the Blood Corpses’ attack dwindled until Hans and Neil could handle the last few.
• Lin Ye questioned Dr. Caroline and learned that the institute’s experiment had devoured the living and undergone an initial mutation.
• A violent tremor shook the institute, and Lin Ye grabbed Caroline and ran toward the exit, believing the Captain was fighting the creature below.
• Lin Ye stopped when he saw a red-haired Caroline outside the laboratory and fired three shots at her.
• The red-haired Caroline froze the bullets in midair, leaving Lin Ye unsure how they could escape or fight her.

Lin Ye defeated Red-haired Caroline after discovering that his experimental weapon released its power when he shouted, then completed the simulation without consuming any simulation counts. He acquired the Human Evolution Map and Dr. Caroline's Gift, but could not understand the research data on the laptop.

• Lin Ye attacked Red-haired Caroline with guns and a saber, while Hans and Neil fired from the sides to help him hold it back.
• Lin Ye shouted as he delivered his final slash, triggering the experimental weapon's energy burst and decapitating Red-haired Caroline.
• Lin Ye destroyed Red-haired Caroline's remains, and Dr. Caroline said the enemy might still be alive if it had split off another body.
• The captain recovered the remains and learned from a supervisory personnel that the experimental weapon's power was triggered by voice.
• Lin Ye ended the simulation and acquired the Human Evolution Map, Dr. Caroline's Gift, and the title All or Nothing.
• Lin Ye opened the Human Evolution Map on his laptop but could not understand its technical information.
