Lin Yi investigated the strange sensations around Group B Class 1 and briefly saw eerie markings on its door and a figure watching him from the corridor. He wondered whether the figure had targeted him before, then approached the classroom door despite Wei Liang’s alarm.

• Lin Yi realized that Li Huiyuan could think in the classroom because sunlight and her altered cognition helped protect her from cognitive collapse.
• Li Huiyuan discovered that Wei Liang had handed her several erotic manga, while Lin Yi recorded his observations in a notebook and invited her to accompany him and Wei Liang.
• As Lin Yi passed Group B Class 1, dizziness let him glimpse strange carvings on the wall and green marks and mist around the classroom door handle.
• Lin Yi saw a hooded or cloaked figure in the dark end of the corridor, felt it watching him, and then watched it disappear as his vision returned to normal.
• Lin Yi wondered whether the figure was the one he had glimpsed on May 6 and considered whether his ignorance had kept it from attacking him.
• Lin Yi walked up to Group B Class 1’s door to inspect its handle, and Wei Liang urgently tried to stop him from opening it.

Lin Yi realized that Li Huiyuan could see green smoke from the Tomato Sauce residue, then struggled against a growing urge to explore the Campus. After a seemingly ordinary bathroom visit, he saw a white liquid humanoid impersonate Wei Liang and discovered that Wei Liang was missing.

• Lin Yi found plaster-like residue on the door handle, and Li Huiyuan spotted green smoke that vanished as the Tomato Sauce finished turning to fragments.
• Lin Yi reasoned that Li Huiyuan could serve as an extension of his vision, then grew alarmed when his curiosity about exploring the Campus seemed to intensify.
• Lin Yi calmed himself after becoming caught in an internal struggle, and he and Wei Liang went to the bathroom with Li Huiyuan heading to the women's room.
• After washing his hands, Lin Yi saw a false Wei Liang beyond the ventilation window and watched it lose its human shape and disappear as a white liquid creature.
• Lin Yi returned to the men's room and found that Wei Liang was gone.

Lin Yi discovered a gap in his memory after briefly encountering a fake Wei Liang, then identified and defeated an impostor wearing Li Huiyuan’s face. The creature melted in sunlight and crumbled into powder, while Lin Yi and Wei Liang hurried to find the real Li Huiyuan inside the women’s room.

• Lin Yi realized he had lost about a minute of memory, though Wei Liang said they had been together during that time.
• After hearing a scream from the women’s room, Lin Yi and Wei Liang cautiously approached and saw an apparent Li Huiyuan running toward them.
• Lin Yi recognized that the approaching Li Huiyuan was an impostor, dodged its lunge, and kicked it out into direct sunlight.
• Lin Yi denied the creature’s claimed identity, causing it to lose its disguise and melt into a White Grimer under the sunlight.
• Wei Liang broke the White Grimer with a thrown stone, and Lin Yi and Wei Liang went to check on the real Li Huiyuan.

Lin Yi rescued Li Huiyuan from an identity crisis caused by a lookalike creature, then decided to explore the Teaching Building with her. They left Wei Liang to return to class and set out to investigate the building’s elevator despite the rules denying that one existed.

• Li Huiyuan described seeing a silent double of herself in the restroom mirror, then began doubting her identity and freezing into a stone-like state.
• Lin Yi used a folded notebook page as a fake Student ID and repeatedly supplied Li Huiyuan’s name and Student Number until she recovered.
• Lin Yi reasoned that the plaster-liquid creatures copied forms anchored by people’s thoughts and tried to hypnotize victims into accepting their identities.
• Li Huiyuan asked to accompany Lin Yi on his exploration, while Wei Liang returned to Group B Class 2 to wait for them.
• Lin Yi chose to investigate the Teaching Building’s elevator first, despite the rules claiming the building had no elevator.

Lin Yi investigated the Teaching Building elevator with Li Huiyuan, using her to observe the area before approaching it himself. When he opened the doors, he found the car packed with twisted nonhuman classmates whose staring eyes seemed to echo the Art Building murals, and he retreated to the sunlit corridor as a strange rustling sound began.

• Lin Yi rejected Li Huiyuan's plan to survive without a Student ID and told her to focus on finding Student Commemorative Coins.
• Lin Yi had Li Huiyuan observe the elevator area from a distance, then watched it himself without noticing anything abnormal.
• Lin Yi decided to approach the elevator while it was still daylight and pressed the up button.
• The elevator doors opened to reveal a cramped car stuffed with twisted nonhuman classmates and protruding eyeballs.
• Lin Yi backed out of the dark corner as the eyeballs searched the area, then heard a rattling rustle.

Lin Yi discovered that the fleshy nonhuman classmates trapped in the elevator could be harmed by sunlight reflected with Li Huiyuan’s mirror. After the elevator shut on some of them, Lin Yi considered returning at dusk to investigate the elevator, but left without finding a place to hide his camera.

• Lin Yi heard the fleshy nonhuman classmates arguing inside the elevator before several were squeezed out into the sunlight.
• One lump of flesh tried to bewitch Li Huiyuan into pressing the elevator’s up button, but Lin Yi pulled her back from the shadowed area.
• Lin Yi used Li Huiyuan’s mirror to reflect sunlight onto the trapped flesh, roasting it and concluding that the mirror could serve as equipment against the nonhuman classmates.
• Lin Yi reasoned that the elevator’s interior might reveal important clues and considered returning at dusk to observe it.
• Lin Yi tried to find a place to leave his Digital Camera to record the elevator but abandoned the idea.

Lin Yi and Li Huiyuan encountered Xu Shunkang and Xie Huayang at the elevator, where Xie Huayang destroyed the Nonhuman Classmate’s remains and explained how sunlight could eliminate them. Lin Yi then asked Xu Shunkang to explain what the things were and how they became classmates, leaving Xu Shunkang poised to reveal more about the Campus.

• Lin Yi told Li Huiyuan that elevator creatures entered classrooms at night and killed students when the lights went out.
• Xu Shunkang and Xie Huayang found the dried Grimer Form, and Xie Huayang broke it open to reveal a blood vessel inside.
• Xie Huayang severed the blood vessel with his Baseball Bat, absorbed its tomato sauce, and used sunlight to destroy the remains.
• Xie Huayang warned Lin Yi to use pure sunlight to eliminate the creatures, while Xu Shunkang urged him to avoid exploring the Campus’s secrets.
• Lin Yi admitted he wanted to explore and asked Xu Shunkang what the nonhuman things were and how they became classmates.

Xu Shunkang explained that Night-Walking Species were contaminated beings that could, in a certain sense, be sculptures, while Lin Yi tried to learn more about them. Li Huiyuan was pulled into a frightening vision in which she realized she was a sculpture, but Lin Yi called her back; afterward, he continued questioning Xu Shunkang with just over an hour left to explore.

• Xu Shunkang described Night-Walking Species as living or dead aberrations animated by contamination and said they were sculptures in a certain sense.
• Lin Yi summarized the rules about campus sculptures, and Xu Shunkang warned that believing sculptures could move meant Lin Yi had entered the magnetic field's vortex.
• Li Huiyuan imagined a sculpture bearing her name, realized she was that sculpture, and fell into a dark, confused state as a voice called to her.
• Lin Yi repeatedly called Li Huiyuan's name until she regained focus, while Xie Huayang prepared to wake her with his Baseball Bat.
• Lin Yi told Xu Shunkang and Xie Huayang that the Green Apron Chef had eaten Li Huiyuan's Student ID, then explained that she was staying with him to survive.
• Xu Shunkang accepted that Lin Yi could take Li Huiyuan along, offered cryptic advice, and Lin Yi redirected their conversation to Night-Walking Species while checking the time.

Xu Shunkang explained how campus contamination, student identities, and lost student IDs could turn experience students into night-walking species. Lin Yi learned that the Sailor Uniform Girl was not an art student but a night-walking species, though Xu Shunkang had only used her as an example and did not explain what she was.

• Xu Shunkang told Lin Yi and Li Huiyuan that people could control contamination and use it as a power, then explained how campus identities and student IDs anchored students to protective rules.
• Li Huiyuan revealed that she had seen green fog, and Xu Shunkang discovered that the mark left by Green Hat had vanished after Lin Yi peeled it off.
• Xu Shunkang explained that weakening willpower and distorted cognition increased contamination, while unstable students risked breaking rules, losing their student IDs, and becoming night-walking species.
• Lin Yi said he thought art students transformed into night-walking species, and Xu Shunkang clarified that he had called the Sailor Uniform Girl an art student to avoid destabilizing Lin Yi's cognition.
• Lin Yi realized Xu Shunkang meant the Sailor Uniform Girl was a night-walking species and asked what she actually was.

Lin Yi learned how Night-Walking Species formed and how sunlight could turn them into Plaster-like figures, while Xu Shunkang and Xie Huayang secretly discussed Lin Yi’s severe Contamination and the forces guiding him. Lin Yi and Li Huiyuan then headed toward the Covered Bridge, where he stopped to look outside.

• Xu Shunkang explained that Night-Walking Species were beings eroded by Fog and described their transformation, while warning Lin Yi not to investigate Sculptures too closely.
• Xu Shunkang refused to explain more about Chefs and left with Xie Huayang after Lin Yi asked about them.
• After Lin Yi departed, Xu Shunkang and Xie Huayang discussed his extreme Contamination, the school authorities’ possible plans for him, and the growing signs of danger around campus.
• Li Huiyuan told Lin Yi that she had offered herself as an example because she hoped to earn his help in return for providing useful information.
• Lin Yi and Li Huiyuan reached the Covered Bridge in Building B, where Lin Yi stopped and looked outside.

Lin Yi discovered that the moss on the Covered Bridge hinted at how the campus changed during Layer Drop, then slipped into a distorted layer shaped by his own deductions. He chose to remain there rather than return to the normal Teaching Building, leaving the strange world around him transformed again.

• Lin Yi noticed the Covered Bridge's moss grew in an unnaturally crooked pattern and theorized that it reflected the campus during Layer Drop.
• Lin Yi imagined the Teaching Buildings as modeling clay and mentally reshaped them into an abstract fortress based on the moss's pattern.
• Lin Yi returned from his thoughts to find Li Huiyuan missing and the Covered Bridge and Teaching Buildings distorted to match his imagined design.
• Li Huiyuan reappeared and shook Lin Yi, who saw his normal self standing across a thin boundary in the ordinary Teaching Building.
• Lin Yi realized he could cross back into the normal layer or remain in the stable world he had created through imagination, and he withdrew his step toward the boundary.

Lin Yi discovered that Contamination had appeared as white fog beneath the Covered Bridge in his imagined world, then returned to reality mentally exhausted. After spotting a Night-Walking Species watching him, he used Li Huiyuan’s mirror to focus sunlight on it and began destroying it.

• Lin Yi saw Contamination fog beneath the Covered Bridge in his imagined world and escaped back to reality as fatigue drained his mental strength.
• Lin Yi suspected Contamination had infiltrated Imaginary Daylight, then rested with Li Huiyuan and learned she had seen white-and-green fog coming from him.
• Lin Yi spotted a Night-Walking Species with a huge bloodshot eyeball clinging to the ceiling corner.
• Lin Yi borrowed Li Huiyuan’s mirror and reflected sunlight onto the creature, making its eyeball fall off and harden into a plaster-like substance.
• Lin Yi continued burning the Night-Walking Species with sunlight until it lost its grip and fell to the floor.

After a night-walking species died, Lin Yi was struck by green particles that left him with an invisible, seemingly permanent mark that might identify him as its killer. While heading back to Building A, he saw through the Teaching Building’s walls and discovered countless night-walking species lurking inside, suggesting it was their nest.

• Lin Yi watched the night-walking species harden into a sculpture, then saw green particles home in on him and leave a tattoo-like mark on his chest.
• Lin Yi reasoned that the mark could identify him to other night-walking species as the one who killed their kind, and decided to ask Tian Bufan and Wei Shan about it.
• Lin Yi and Li Huiyuan prepared to return to Building A, but Li Huiyuan worried the sculpture might revive at night, so Lin Yi went to collect stones.
• Less than ten minutes later, Lin Yi’s altered vision returned, revealing the green mark and countless night-walking species hidden in the walls of Teaching Building’s Building C.
• Lin Yi realized the Teaching Building might be the night-walking species’ nest and connected their nighttime emergence to the rule forbidding students from leaving classrooms after 21:00.

Lin Yi discovered that his heightened vision revealed green contamination and a hidden Covered Bridge from Building C, leading him to suspect that Building D might be the Art Building. He and Li Huiyuan returned to Building B, where Lin Yi considered whether the fog concealed a sea and whether the bridges connected the buildings across layers, but he remained unsure of his theory.

• Lin Yi saw green fog coming from himself and Li Huiyuan, then wondered whether his contamination had awakened the Night-Walking Species in Building C.
• Lin Yi smashed the sculpture-like substance with a rock; it crumbled into dust, and Li Huiyuan reported seeing its green fog disappear.
• Lin Yi and Li Huiyuan crossed the Covered Bridge back to Building B, and Lin Yi realized his altered vision had revealed another bridge leading from Building C in the opposite direction.
• Lin Yi recalled a castle-like Building D and considered whether it was the Art Building, despite the Campus notice denying that a castle existed.
• Lin Yi connected the hidden bridge, the mountains beyond the Wooded Belt, and waves beneath the fog, then speculated that the Covered Bridge might lead to the Art Building across overlapping layers.
• Lin Yi questioned whether the Campus could influence his thoughts and prevent him from falling through a layer when he approached the truth.

Lin Yi and Li Huiyuan investigated the Teaching Building’s Stairwell, where they saw mirrored flights of stairs and discussed how contamination let people perceive other layers. Lin Yi suspected the Stairwell could trap people in endless spirals, and imagined Li Huiyuan descending into it as the chapter ended.

• Lin Yi pulled Li Huiyuan out of a layer after she became entranced by the Stairwell and began dropping layers.
• Lin Yi and Li Huiyuan entered the Stairwell hand in hand, saw two mirrored flights of stairs, and retreated outside.
• Li Huiyuan described seeing the stairs twist together and a flight leading down, while Lin Yi explained how contamination exposed other layers.
• Lin Yi inferred that contaminated Experience Students without Student IDs could see the stairs to Basement Level One, and wondered whether Li Huiyuan could only see them in indirect light.
• Lin Yi theorized that the Stairwell drifted between layers and could trap people, then imagined Li Huiyuan entering it and descending an endless spiral.

Lin Yi used a grounding routine based on his identity and Student ID to safely guide Li Huiyuan through the Stairwell, though the fourth floor revealed a passage full of hostile night-walking species watching him. They returned to the classroom, where Lin Yi found another group of newcomers and suspected one of Li Huiyuan’s fellow arrivals had died.

• Lin Yi’s imagined vision showed Li Huiyuan turning into a statue as green fog and particles poured from the wound on her back, then the vision abruptly ended after only a minute had passed.
• Lin Yi held his Student ID and repeated his identity and location, restoring the Stairwell to normal, then led Li Huiyuan up to the fourth floor and back down safely.
• At the fourth floor, Lin Yi stopped his grounding recitation and saw green fog and countless night-walking species packed into a hidden staircase, so he quickly took Li Huiyuan back into the sunlight.
• Lin Yi and Li Huiyuan returned to the classroom, where Lin Yi counted the students and suspected that one of the experience students who arrived with her had been killed.
• Lin Yi noticed seven new experience students, including a nervous middle-aged man and several newcomers listening to Pan Jian’s female companion recount the previous night’s events.

Lin Yi and his companions headed to dinner as a middle-aged Experience Student discovered that two pocket watches showed different times. As the Cafeteria opened, Lin Yi planned to search for its hidden Convenience Store and ask Xu Shunkang’s group for help getting Li Huiyuan there.

• Lin Yi returned to the Lecture Hall with Li Huiyuan, and Wei Liang joined them as they left for dinner.
• The Experience Students and Athlete Students filed out of the classroom, while a middle-aged man compared two pocket watches and recorded their different times in a notebook.
• Lin Yi met Wei Shan on the way to the Cafeteria and asked whether he had visited the bathroom after one that afternoon; Wei Shan confirmed that he had.
• At the Notice Board, Lin Yi gave out copies of the Cafeteria Rules and asked whether they still applied to Li Huiyuan, who said she would follow them as best she could.
• Lin Yi searched for the Convenience Store outside the Cafeteria but could not find it, then planned to look inside and ask Xu Shunkang’s group to show Li Huiyuan where it was.

Lin Yi noticed Li Huiyuan deteriorating as they entered the Cafeteria and learned that the Blue Apron Chef had secretly urged her to find the Convenience Store. After discovering green fog leaking from a scar in her palm and drifting toward his own, Lin Yi wondered whether his Green Fog Mark was drawing it in.

• Lin Yi watched a terrified girl plead with Xu Shunkang for help, then warned Li Huiyuan not to get involved and led her into the Student Passage.
• Lin Yi noticed Li Huiyuan was bothered by the passage lights and held her hand as they avoided the Blue Apron Chef.
• The Blue Apron Chef silently told Li Huiyuan to find the Convenience Store, and Lin Yi realized he could hear its message.
• Wei Liang interrupted Li Huiyuan as she tried to explain what the Chef had said, teasing her and Lin Yi for holding hands.
• Lin Yi spotted a scar in Li Huiyuan's palm releasing green fog that drifted toward his own hand, then shook it away.

Lin Yi and Li Huiyuan went to the Student Dining Hall to find the Convenience Store after a Blue Apron Chef warned her to hurry. At the entrance, they discovered an upside-down Green Apron Chef targeting Li Huiyuan, and Wei Liang rushed in before Lin Yi could stop him.

• Li Huiyuan told Lin Yi that the Blue Apron Chef had directed her to find the Convenience Store before “they” noticed her, and Lin Yi suspected the Night-Walking Species and Green Apron Chefs might be involved.
• Lin Yi decided to enter the Student Dining Hall with Li Huiyuan, then heard the Blue Apron Chef urgently warn that it would soon be too late.
• Lin Yi lifted the Plastic Air Curtain, sensed a threat above him, and stopped himself from stepping inside as tomato sauce dripped onto his foot.
• Li Huiyuan looked up despite Lin Yi's warning and saw a Green Apron Chef hanging upside down; it called her by name and repeated her Student Number, leaving her unable to respond to Lin Yi.
• Wei Liang charged past Lin Yi and Li Huiyuan, seized the Plastic Air Curtain, and tried to pull it up, but the Green Apron Chef's head blocked it.

Lin Yi searched the Student Dining Hall for the Convenience Store while keeping Li Huiyuan from responding to the Green Apron Chef’s attempts to lure her. After they failed to find it, Wei Liang left for the classroom, and a Green Apron Chef emerged to chase him.

• Wei Liang accidentally pulled the Green Apron Chef down from the ceiling with the Plastic Air Curtain, then kicked it while mistaking its resistance for a broken curtain.
• Lin Yi led Wei Liang and Li Huiyuan into the Student Dining Hall and searched the sunlit area near Meal Window No. 1 for a place without artificial lighting.
• The Green Apron Chef tried to draw Li Huiyuan’s attention by claiming it had her Student ID, but Lin Yi distracted her with yogurt and led her away.
• Lin Yi and Li Huiyuan searched the dining hall for nearly twenty minutes without finding the Convenience Store or Xu Shunkang and the other athlete students.
• Wei Liang left for the classroom, and a Green Apron Chef crawled out of Meal Window No. 10 and chased him out of the dining hall.
• A diner set a tray with what looked like a bloody heart opposite Lin Yi and Li Huiyuan, but Lin Yi saw it as a tomato when he looked again.

Lin Yi recognized the Convenience Store as an alternate Student Passage and led Li Huiyuan toward it as the Cafeteria lights failed. A dangerous Green Apron Chef appeared in the darkness just three centimeters from them, leaving their escape uncertain.

• After Li Huiyuan’s blood attracted nonhuman classmates, Lin Yi led her toward the Plate Return Area while they pursued them.
• The Cafeteria lights began flickering, and Lin Yi searched the area instead of immediately heading for the Student Passage exit.
• Lin Yi spotted the briefly revealed Convenience Store near the former Meal Window No. 1 and realized they could use it to leave by purchasing an item.
• A pitch-black figure appeared during the blackouts as Lin Yi and Li Huiyuan ran toward the Convenience Store, while the darkness spread through the Student Dining Hall.
• An incandescent light went out directly ahead, and Lin Yi stopped just before the Green Apron Chef appeared inside the darkness in its humanoid-spider form.

Lin Yi used his mental simulation of the flickering lights to guide Li Huiyuan through the darkening Student Dining Hall and into the Convenience Store. Inside, they discovered that the store opened into a vast, shelter-like space between layers, while Lin Yi remained uneasy about the danger behind them.

• Lin Yi realized the lights were going out in a spreading pattern and mentally calculated a rhythm that let him lead Li Huiyuan safely toward the Convenience Store.
• Lin Yi traced the darkness to Meal Window No. 10 and suspected a danger beyond the Green Apron Chef, while Li Huiyuan's determination to survive strengthened.
• Wei Liang's voice called from behind them, but Lin Yi warned Li Huiyuan not to look back and hurried her to the Convenience Store.
• Lin Yi took a roll of biscuits and crossed the Convenience Store's glowing threshold with Li Huiyuan, finding an immense, dimly lit space resembling an air-raid shelter.
• Lin Yi guessed the Convenience Store existed in another layer or between layers, then saw that its doorway offered a view back into the Student Dining Hall.

Lin Yi and Li Huiyuan read the Convenience Store Instructions and headed toward the merchandise shelves as darkness and Bone-White Fog closed in. When a terrifying creature crawled into the store, a student in a dark green uniform stepped out and approached it.

• As the Student Dining Hall fell into darkness, Li Huiyuan spotted the Convenience Store Instructions posted on the door.
• Lin Yi and Li Huiyuan read both sets of instructions, which gave different rules for students with and without Student IDs.
• Lin Yi and Li Huiyuan followed the blue exit signs toward the miscellaneous shelves while the Bone-White Fog gathered outside the entrance.
• The store’s lights turned red, Lin Yi became unable to move, and Bone-White Fog poured inside as frost spread across the floor.
• A blue-gray creature crawled through the doorway, and an unidentified student wearing a dark green uniform stepped past Lin Yi toward it.

Lin Yi witnessed Mao Feiyang’s perspective in another layer of the Convenience Store, where Mu Daxian fought off the Night-Walking Species, and concluded the fog could eventually overrun the store. While searching for Student Commemorative Coins with Li Huiyuan, they found coins beyond the lit area, but crossing into the darkness injured her foot and began to numb it.

• Mu Daxian transformed his drawing board into a rune-inscribed cross and used it to turn a Night-Walking Species into a plaster-like sculpture.
• Lin Yi realized he was seeing through Mao Feiyang’s perspective as Mu Daxian defended the Convenience Store from a horde of Night-Walking Species and ordered Mao Feiyang to find Student Commemorative Coins.
• Lin Yi returned to his own layer and warned Li Huiyuan that the thick fog might eventually enter the Convenience Store.
• Lin Yi and Li Huiyuan searched the shelves but found all the Student Commemorative Coins in the lit area missing.
• Lin Yi pulled Li Huiyuan back when she stepped into the darkness, but part of her foot had already turned gray, cold, and numb.

Lin Yi and Li Huiyuan searched the Convenience Store for Student Commemorative Coins as strange calls and tremors grew stronger. When deadly fog began swallowing the store, Lin Yi turned back to rescue Li Huiyuan after she could no longer walk.

• Lin Yi and Li Huiyuan left the marked route to search nearby shelves while a voice called their names from the shadows.
• As the calls and thudding grew stronger, Lin Yi led Li Huiyuan toward the exit and told her to grab snacks when they found no Student Commemorative Coins.
• The Convenience Store shook, and Lin Yi glimpsed the Green Apron Chef behind the entrance as white fog began overtaking the doorway.
• Lin Yi warned Li Huiyuan that the fog was about to enter, and they ran as night-walking species and Green Apron Chefs advanced through the store.
• Li Huiyuan lost feeling in her feet and told Lin Yi to leave her behind, so he went ahead before returning with a flowered bedsheet.
