Chapter Summaries

Lin Yi learned that the creature that attacked the Campus was an Ashes Apostle and resolved to investigate its connection to Ashes. Back in class, Li Huiyuan and Wei Liang teased him over his damaged clothes, while Wei Liang’s suspicious reaction to Lin Yi’s bag left Lin Yi wondering what he knew.

• Xu Shunkang told Lin Yi that an Ashes Apostle had attacked the Campus and that Boss had driven it away after many suffered heavy casualties.
• Lin Yi connected Ashes Apostles to the Ashes on him and decided to uncover their relationship.
• Li Huiyuan pressed Lin Yi about changing clothes in Head Teacher 040’s office, then grew jealous when Wei Liang joked about it.
• Wei Liang brought Lin Yi a spare uniform and shoes, which astonished Lin Yi because Wei Liang seemed to have anticipated his need.
• Lin Yi tested Wei Liang by offering him Lao Mo’s bag, but Wei Liang abruptly refused to inspect it and urged Lin Yi to change clothes in the classroom.

Lin Yi changed clothes in the bookshelf area and was pulled into a Dreambuilding vision of the Abandoned Classroom, where he saw a passage connecting the eerie book The Law-Establisher's Words to his past self in the Library. He escaped by anchoring himself to the classroom's time, then found the Ouroboros Ring on his finger despite its Stone Box remaining closed, leaving him wondering whether the Abandoned Classroom and Library were connected.

• Wei Liang secretly tore a blank page from Lin Yi's Memo Pad and put it in his pocket.
• Lin Yi went behind a bookshelf to change while Li Huiyuan watched nearby.
• Lin Yi saw an upside-down broken sculpture and found himself back in the Abandoned Classroom, where the sculptures' voices and a widening fissure overwhelmed him.
• Lin Yi saw a passage leading toward The Law-Establisher's Words at one end and his past self in the Library at the other.
• Lin Yi used his watch to establish the classroom's time anchor, and Wei Liang's voice helped shatter the Dreambuilding.
• Lin Yi discovered the Ouroboros Ring on his finger even though its Stone Box was still shut, then wondered whether the Abandoned Classroom and the Library were connected.

Lin Yi found a newly written diary entry in a Hentai Manga that described events in the Art Building and questioned how the information could keep changing. Suspecting the answer might involve sleep and dreambuilding, he decided to initiate dreambuilding himself while Li Huiyuan watched over him.

• Lin Yi asked Li Huiyuan to watch him while he browsed the Hentai Manga, warning her to wake him if his layer became unstable.
• Lin Yi found an entry dated May 10, Year X023, describing Mu Daxian's disappearance and the ongoing invasion in the Art Building.
• Lin Yi noticed new information appear in the book and deduced that old information faded over time, ruling out his theory that the classroom's mysterious extra person had written it.
• Wei Liang called from the Lecture Hall and asked whether Lin Yi had fallen asleep, prompting Lin Yi to consider sleep as a clue.
• Lin Yi told Li Huiyuan he would initiate dreambuilding and asked her to hold his hand and wake him if anything seemed wrong.

Lin Yi used his perception to follow the information in the book across layers and saw the Library through the eyes of an Art Student named Li Zidan. As he fled back toward his body, a presence detected his layer leap and began collapsing the passage around him.

• Lin Yi focused his perception on the book while Li Huiyuan held his wrist, and he followed its chaotic information through a sequence of vortices resembling The Starry Night.
• Lin Yi reached the Library and saw Art Students reacting to Li Zidan, whose body he realized he was viewing through his own perception.
• Little Angel and Little Demon Sculptures warned Lin Yi to leave and find someone first, while an Art Teacher approached with a Supernatural Creation.
• Lin Yi escaped Li Zidan's body and began retracing his path, but countless eyes appeared in the vortices as the Admonition's phrases echoed through the passage.
• The presence behind the eyes sensed Lin Yi's layer leap and began destroying the passage, threatening to trap him inside.

Lin Yi escaped the shifting layers and returned to the Bookshelf Area, where he learned that Li Huiyuan had shared his perception through the Ouroboros Ring. Meanwhile, Art Students investigated a brief mental intrusion and prepared for another dangerous night, and Lin Yi left the library after an awkward exchange with Li Huiyuan.

• Lin Yi returned from the collapsing passage and discovered that Li Huiyuan had seen the Library through their linked perceptions, so he told her to report the experience to Boss.
• Lin Yi and Li Huiyuan gathered eight volumes of Hentai Manga to take to Liangzi, while Li Huiyuan privately wondered whether she matched Lin Yi’s preferences.
• Art Students questioned Li Zidan after he briefly appeared mentally eroded, but their teacher could find no cause and ruled out perception penetration as impossible.
• The Art Teacher ordered the Art Students back to the Art Building to prepare for a deadly night, while the sculptures watched them leave unnoticed.
• Lin Yi saw Head Teacher 040 leave the classroom, and Li Huiyuan teased him by offering to wear black stockings before he blurted out that she was too young.

Lin Yi and Li Huiyuan left the classroom to visit Head Teacher 040, while Wei Liang stayed behind reading. Mountain Man approached Wei Liang and questioned him about a missing student, Song Rentou.

• Lin Yi and Li Huiyuan traded jokes with Wei Liang before settling down to read hentai manga in the classroom.
• Lin Yi watched Wei Liang, then noticed Li Huiyuan's embarrassment and said he planned to return clothes to Head Teacher 040 and explore the Teaching Building.
• Li Huiyuan insisted on accompanying Lin Yi, claiming she would keep an eye on him for Boss, and they left the classroom together.
• Xu Shunkang and the Athlete Students discussed Lin Yi and Li Huiyuan's closeness, Lin Yi's contamination, and Xu Shunkang's hopes of pursuing Senior Xia Lian.
• Mountain Man approached Wei Liang after Lin Yi and Li Huiyuan left, and asked whether Wei Liang had been involved in Song Rentou's disappearance.

Mountain Man confronted Wei Liang about his identity and past, then left after warning him about people carrying “ashes.” Lin Yi investigated Yuan Lijian’s records and the mysterious figure who fled the classroom, learning why the figure might be dangerous while deciding the Memo Pad needed to be destroyed.

• Mountain Man questioned Wei Liang about Song Rentou and whether Wei Liang had been at the school in Year X999, then left after warning that some people would do anything to carry “ashes.”
• Lin Yi and Li Huiyuan visited Head Teacher 040, and Lin Yi reviewed Yuan Lijian’s sign-in records, which showed no unusual activity.
• Head Teacher 040 explained that Yuan Lijian’s contamination kept growing because he apparently had not returned to the Dormitory to shower, prompting Lin Yi to treat worsening suspicions as conclusions when necessary.
• Lin Yi asked about the nonexistent person who had rushed out of the classroom, and Head Teacher 040 said she believed it was nonhuman but could identify no known kind of creature it matched.
• Head Teacher 040 warned that recordings of dangerous entities could become sources of contamination, and Lin Yi resolved to destroy the Memo Pad he carried.

Lin Yi and Head Teacher 040 connected Yuan Lijian to the puppet assembled in the classroom and discussed how Lin Yi could reach the Teaching Building’s fifth floor and above. Head Teacher 040 explained that a brief layer fluctuation caused by clouds blocking the sun could provide an opportunity, and Lin Yi left to investigate before asking who the office door was meant to keep out.

• Head Teacher 040 realized that the nonexistent person might be a puppet, and Lin Yi linked the idea to Yuan Lijian stealing mystical substance and assembling one.
• Lin Yi and Head Teacher 040 agreed to treat Yuan Lijian as a suspect, though Lin Yi said he would focus on his own plans.
• Lin Yi asked how to reach the Teaching Building’s upper floors, and Head Teacher 040 explained that layer fluctuations could let him enter during a sub-shadow state when clouds blocked the sun.
• Head Teacher 040 warned Lin Yi to protect himself and avoid risks, while Lin Yi checked the time and prepared to leave for the Teaching Building.
• Lin Yi asked why the Teachers’ Office door was locked by day but left unlocked at night, wondering whom it was meant to guard against.

Lin Yi deduced that the Yuan Big Head incident had been a ritual engineered to bring an Ashes Apostle onto the Campus, and Head Teacher 040 confirmed that a similar creature had likely injured her. After leaving the office with Li Huiyuan, he observed Mountain Man's visit and invited her to explore the Teaching Building's upper floors.

• Head Teacher 040 explained that she had left the office door open to hunt nonhuman entities after suffering injuries while testing a passing creature's strength.
• Lin Yi connected Teacher 039's mistaken identification of an Ashes Apostle with the Yuan Big Head incident and deduced that the Infiltration Force had used Yuan Big Head and Mu Daxian to bridge two layers during the seventieth Gray Fog Invasion.
• Lin Yi concluded that Yuan Big Head and the students with him had died when the Ashes Apostle descended, while the Night Watchman might have saved Mu Daxian.
• Head Teacher 040 agreed that an Ashes Apostle had probably injured her and reassured Lin Yi that his treatment had revealed no ashes in her body.
• Lin Yi and Li Huiyuan encountered Mountain Man outside the office, then secretly watched as Head Teacher 040 admitted him after he identified himself as Yuan Lijian.
• Lin Yi invited Li Huiyuan to explore the fifth floor of the Teaching Building and above as his friend rather than as cannon fodder.

Little Genius returned to Campus as a puppet, but Wei Shan tore it apart and an impersonator named Wei Liang devoured its head. Meanwhile, Lin Yi and Li Huiyuan reached the fourth floor of Teaching Building B and watched the clouds while planning when to continue upstairs.

• Lin Yi sensed something strange in the Wooded Belt and left for the Stairwell with Li Huiyuan.
• Little Genius emerged from the Wooded Belt and approached Teaching Building B, but Mountain Man avoided it by ducking into Group B Class 2.
• Little Genius knocked on the Teachers' Office door until Wei Shan recognized it as nonhuman, dragged it to the Men's Restroom, and dismembered it.
• An impersonator calling himself Wei Liang retrieved Little Genius's head and ate it, while Little Genius cried out in terror.
• Lin Yi and Li Huiyuan reached the fourth floor, where Lin Yi observed the clouds and waited for a chance to continue upstairs.

Lin Yi and Li Huiyuan crossed the unstable Layer in the Teaching Building’s Stairwell, fending off Night-Walking Species and resisting the passage’s mind-warping calls to reach the forbidden fifth floor. There, Lin Yi reassured Li Huiyuan that some Teaching Building Rules no longer applied to them and began explaining what the Rules meant.

• Lin Yi and Li Huiyuan entered the Stairwell hand in hand as the light faded, and a swarm of Night-Walking Species appeared.
• Lin Yi used his Admonition to make the Night-Walking Species scatter and opened a path through the Layer, then led Li Huiyuan up the stairs.
• They encountered overlapping Grinning Angels, hostile calls from inside the walls, and other disturbances that weakened their minds.
• Lin Yi shouted his Admonition again and brought Li Huiyuan through the Layer to the Teaching Building’s fifth floor.
• Zhao Lingxiao heard Li Huiyuan’s scream on the fourth floor and hurried to the Stairwell, but Lin Yi and Li Huiyuan had already vanished inside the Layer.
• Li Huiyuan worried that entering the forbidden fifth floor broke the Rules, and Lin Yi told her they were moving beyond the category of people bound by some of them.

Lin Yi and Li Huiyuan explored the fog-shrouded fifth floor of the Teaching Building, where they encountered a group of Fanatics. Lin Yi agreed to follow their leader to meet a teacher, planning to learn more while preparing to fight if necessary.

• Lin Yi explained to Li Huiyuan that he was studying the Campus rules so he could find a way to rescue his roommate from the Art Building.
• Lin Yi and Li Huiyuan examined the fifth floor, where dense white fog obscured the corridors and classrooms.
• A Fanatic appeared behind Lin Yi and asked whether they had been invited; Lin Yi realized the rules' warning about familiar people changing referred to Fanatics.
• More Fanatics emerged from the fog and surrounded Lin Yi and Li Huiyuan, including figures dressed in bandages.
• Lin Yi agreed to follow the Fanatic to see the teacher and told Li Huiyuan to keep holding his hand, ignore what she saw, and wake him if he fell into another Layer.

Lin Yi and Li Huiyuan followed a Fanatic through the fog-shrouded Forbidden Zone B-5F to Group B Class 15, where Lin Yi learned the area had suffered a disaster about ten years earlier. Inside the ruined classroom, he encountered the Weird Art Female Teacher again, and she greeted him as they met once more.

• Lin Yi teased Li Huiyuan about her miniature Baseball Bat, and she threatened to tell Boss about his past misadventure with the Head Teacher.
• Lin Yi confronted the Fanatic escorting them and slammed his head against a wall until he explained that the area had been operating normally before a disaster roughly ten years ago.
• Lin Yi questioned the Fanatic about their destination, then followed him and Li Huiyuan into Group B Class 15.
• Lin Yi examined the fog-filled classroom and found hostile Fanatics among its battered desks, scattered papers, and unfinished chalk writing.
• Lin Yi recognized the female teacher as the Weird Art Female Teacher he had encountered before, and she smiled at him and said they had met again.

Lin Yi questioned the Weird Art Female Teacher about the Black Moon Apostles and the Campus, but she could answer almost none of his questions. When he brought up the Ashes Apostles, her reaction confirmed his suspicions, and she blocked him from leaving.

• The Weird Art Female Teacher recognized that Lin Yi had returned, and he agreed to speak with her while giving the false name Xiao Zi.
• The Weird Art Female Teacher described her group as Black Moon Apostles pursuing Glorious Evolution and becoming light, while Lin Yi connected that goal to becoming Angels.
• Lin Yi learned that the classroom had once been part of the Teaching Building and that the Campus Rules could be updated, but the teacher could not explain when the building changed or what had happened there.
• When Lin Yi asked about the Ashes Apostles, the Weird Art Female Teacher reacted sharply, confirming that the name mattered to her.
• Lin Yi tried to leave with Li Huiyuan, but the Weird Art Female Teacher ordered him to stay as the Fanatics turned toward him and tightened their encirclement.

Lin Yi and the Weird Art Female Teacher exchanged information about Lao Mo, the Ashes Apostles, and the Fanatics’ plans for Campus. As she explained an ancient disaster that reshaped the Teaching Building, Lin Yi suddenly connected it to other clues.

• Lin Yi claimed Lao Mo had investigated an Ashes Apostle, while the Weird Art Female Teacher said Lao Mo had opposed the Angel and died at the Clock Tower with his heart removed.
• The Weird Art Female Teacher explained that Lao Mo’s heart could power a mystical vessel, and Lin Yi secretly realized it was inside his backpack.
• Lin Yi combined his account with her information and suggested that someone had brought an Ashes Apostle onto Campus to collect its ashes and cause chaos around the Angel.
• The Weird Art Female Teacher revealed that the Fanatics wanted to turn people into Godfolk and would destroy Campus if it no longer served their recruitment needs.
• The Weird Art Female Teacher described an early failed assault on the Art Building that opened a channel for the Angel’s power, summoned Ashes Apostles, and killed a Night Watchman.
• Lin Yi suddenly connected several clues as he listened to her account of the old disaster.

Lin Yi connected Mountain Man and the Ashes Apostles to the Dark Upheaval, then learned that an Ashes Apostle was in the Campus and could be lured by those bearing Ashes. The Weird Art Female Teacher suspected a faction was feeding it, leaving Lin Yi fearing it would come for him that night.

• Lin Yi connected Mountain Man's return to the Campus with the Dark Upheaval and wondered whether the broken sculptures had been calling for Night Watchman-01.
• Lin Yi told the Weird Art Female Teacher about Mountain Man, and she explained that Ashes Apostles were powerful beings who had touched the light and competed for a unique sequence.
• The Weird Art Female Teacher said an Ashes Apostle had entered the Campus after the Principal disappeared and was gradually weakening as its Supernatural Power declined.
• Lin Yi realized the Ashes he carried could draw the Ashes Apostle to him, while the Weird Art Female Teacher explained that Ashes-marked people became its targets and nourishment.
• The Weird Art Female Teacher concluded that a faction collecting Ashes might be trying to feed the Ashes Apostle.

Lin Yi realized the Infiltration Force might be arranging people and resources to create or feed Ashes Apostles, and he feared he was being prepared as material for one. When Zhang Lingzhen returned as a Fanatic and fixated on him, Li Huiyuan stepped in, provoking Zhang Lingzhen into unleashing hostile green aura.

• Lin Yi considered that the Fanatics might be researching a way to create Ashes Apostles together, with the Wrathful Angels as byproducts.
• Lin Yi feared the Campus authorities or the Infiltration Force intended to use him as high-grade material for the existing Ashes Apostle.
• Zhang Lingzhen arrived at the Art Classroom with Senior Ren and other former Blue Bus passengers, many of whom had joined the Fanatics.
• Lin Yi suspected the first passengers to leave the bus had been planted by the Infiltration Force and wondered what role he played in their plan.
• Zhang Lingzhen approached Lin Yi with greed and aggression, and Lin Yi sensed that her body had been rebuilt with parts that were not originally hers.
• Li Huiyuan pulled Lin Yi behind her and confronted Zhang Lingzhen, who shifted her attention to Li Huiyuan and erupted in hostility.

Li Huiyuan defeated Zhang Lingzhen in close combat, but Lin Yi absorbed Zhang Lingzhen’s dark green aura before it could injure her. After Ren Jianxiong reported Grinning Angels in the Teaching Building, the Weird Art Female Teacher led the Fanatics, Lin Yi, and Li Huiyuan out, where Lin Yi discovered the aura of ashes and suspected the Fanatics were collecting it.

• Li Huiyuan shattered Zhang Lingzhen’s fangs with her Mini Baseball Bat and kicked her away, but Zhang Lingzhen’s dark green aura ensnared Li Huiyuan.
• Lin Yi absorbed the aura and rescued Li Huiyuan, alarming the Weird Art Female Teacher and the other Fanatics.
• The Weird Art Female Teacher stopped Zhang Lingzhen from attacking again, while Ren Jianxiong pulled her aside and reported Grinning Angels in the Teaching Building.
• The Weird Art Female Teacher ordered the Fanatics to leave and told Lin Yi and Li Huiyuan to follow them, and Lin Yi agreed so he could see how they avoided the Grinning Angels.
• Outside Group B Class 15, Lin Yi sensed the aura of ashes in the fog and realized the Fanatics were collecting it too.

Lin Yi and Li Huiyuan escaped a distorted floor of the Teaching Building after discovering that the Grinning Angels were drawing Ashes from the Fanatics and consuming the steam released as they burned. They returned to Forbidden Zone-B-5F, where Lin Yi found more Grinning Angel sculptures appearing around the Covered Corridor and Stairwell.

• Lin Yi realized the Grinning Angels had warped the floor and awakened, while the Weird Art Female Teacher led away those who remembered their names and left the other Fanatics behind.
• Lin Yi sensed Ashes falling with the volcanic ash and saw the Fanatics attract and absorb it as the Grinning Angels inhaled the steam from their bodies.
• Lin Yi took Li Huiyuan away from the group after sensing that the Ashes would make the Fanatics catch fire.
• A Fanatic burned to death, and the flames spread through the Grinning Angels as a crystalline substance began forming within the fire.
• Lin Yi led Li Huiyuan out of the distorted space and returned to Forbidden Zone-B-5F, where he spotted more Grinning Angel sculptures near the Covered Corridor and Stairwell.

Lin Yi and Li Huiyuan escaped the Grinning Angels by entering the sealed Group B Class 13, where they discovered the Nonexistent Person trapped beside a breach in the window. Lin Yi investigated the figure and found it had changed since morning, but its nature and the danger posed by the ashes remained unclear.

• Lin Yi used Minecraft and Domain Insight to map the fifth-floor Forbidden Area, spotted shelter in Group B Class 13, and led Li Huiyuan past awakening Grinning Angels.
• Li Huiyuan used her Athlete Student ID to unlock the classroom door, and Lin Yi shut and locked it behind them as Grinning Angels gathered outside.
• Lin Yi searched the abandoned classroom and found a breach in the window letting in salty sea air and drifting ashes.
• Lin Yi recognized the trembling figure as the Nonexistent Person from Group B Class 2 and noticed scratches showing it had failed to open the door.
• Lin Yi stopped Li Huiyuan from approaching and carefully examined the Nonexistent Person, discovering that it had changed since morning.
