Ch. 1Student Rules

On May 6, X023, Lin Yi and his classmates traveled through the fog to S City University for a paid seven-day student experience, while studying its unsettling Student Rules. The coach reached the university gate, but the driver refused to open the door while a woman claiming to be a teacher and several students waited outside in the fog.

Ch. 2Don't look back

  • The driver warned passengers not to enter the school until he had checked their name badges, but the passengers pressured him to open the bus doors.
  • Lin Yi noticed that the female teacher's name badge was drawn on paper and warned Wei Liang that she and the students might be the Art Teacher and Art Students.
  • Lin Yi and Wei Liang tried to return to the bus, but the fog disoriented them, and scraping footsteps and urgent calls followed behind them.
  • Lin Yi used Student Rule 7 to keep track of their path and waited for the nearby streetlight to turn on at six o'clock.
  • The streetlight lit, and Lin Yi and Wei Liang ran beneath it, where they found the label Teaching Building-023 and saw the female teacher and students watching from the fog.

Ch. 4Teaching Building

Lin Yi and his companions escaped the abnormal fog by following streetlamps to the Teaching Building, where they discovered it had an impossible eighth floor and found instructions for obtaining student IDs. The chapter ended as Wei Liang warned that the real Teaching Building had no basement, even though the notice directed them underground.

  • Lin Yi ignored the Green Bibbed Chef’s calls, led the group away from the Security Guard, and ran toward a streetlamp while the fog resisted them and imitated Mao Feiyang’s voice.
  • Wei Shan pushed Lin Yi through the light, and the others joined him as the streetlamps drove back the shadows; Mao Feiyang briefly fell under the spell of the calls before catching up.
  • The group reached the Teaching Building and discovered that it had eight floors, despite Wei Liang knowing it should have only four.
  • Inside, Lin Yi read a notice directing participants to Basement Level One to meet their Head Teacher and receive Student IDs, with an alternate route to the Art Teacher if they became lost or unwell.
  • Tian Bufan opened the stairwell door to a basement passage, but Wei Liang warned Lin Yi that the Teaching Building had no basement.

Ch. 5Basement Level One of the Teaching Building

Lin Yi and the others descended a seemingly endless stairwell and emerged back at the Teaching Building, where they found the Teachers' Office and began registering for enrollment. Mao Feiyang could not see the office and followed a noticeboard rule down the stairs alone, while Lin Yi was left to knock at the office door and face a different voice.

  • Wei Liang warned Lin Yi that the Teaching Building had only four floors, but Tian Bufan confirmed the stairwell was real and led the group inside.

  • Tian Bufan identified the Teachers' Office, answered its questions, and entered; Lin Yi then sent the others in one by one.
  • Mao Feiyang could see only a wall where Lin Yi saw the office, recalled the noticeboard's rule, and rushed down the stairwell alone.
  • At 20:00, Lin Yi knocked on the office door and heard a woman ask whether he had come with the food delivery.

Ch. 6The head teacher

  • Lin Yi entered the head teacher’s office, noticed a suspicious food container and scraps of paper, and resisted an urge to investigate the container.
  • The head teacher gave Lin Yi his Student ID and the Teaching Building Rules, warning him to protect the ID and explaining that the person wearing her badge would be his head teacher.

Ch. 7Teaching Building Rules

  • Wei Liang unfolded the map hidden inside the rules booklet, and Lin Yi seized it and repeatedly asked how it could be like that.

Ch. 8Athlete Student

Lin Yi investigated the Campus’s distorted roads and streetlights, but thinking about the mystery caused him to fall into a sleep-like state and draw a crowd of eerie classmates. Xu Shunkang warned Lin Yi that learning the Campus’s secrets would make him part of them and prevent him from escaping.

Ch. 10Going to the Restroom

Lin Yi and Wei Liang left Group B Class 2 to use the restroom before the 21:00 curfew, but the fog and an unseen influence disoriented Lin Yi as they made their way through the corridor.

After the Security Guard dragged something out of the classroom and the lights returned, Lin Yi cautiously waited at his desk and heard a classmate ask if he was okay.

  • Lin Yi lost himself in manga, and the Classmate who had targeted him could no longer find him by sight.
  • At 4:30, abnormal Classmates began leaving the lecture hall, and Lin Yi deduced that staying in the classroom overnight was only an option, not necessarily the safe choice.

Ch. 23[I am the head teacher]

Lin Yi traced plaster powder from Little Genius’s corpse to the lectern and found a note repeating “I am the head teacher,” while the head teacher struggled to reaffirm her identity in the office. After Lin Yi and Wei Liang left for lunch, a gust of wind revealed more white forms hidden near Little Genius’s sculpture.

  • Wei Liang found plaster powder on the classroom floor, and Lin Yi followed its trail from Little Genius’s hiding desk to the lectern, where it vanished.

Lin Yi and Wei Liang headed to the Cafeteria with Xu Shunkang and Xie Huayang, while Lin Yi investigated impossible spatial distortions and unsettling traces around the Campus. At the Cafeteria entrance, Lin Yi and Wei Liang began reading its rules, while Xu Shunkang and Xie Huayang refused to do so.

  • Lin Yi noticed that the Cafeteria’s ban on entering during Abnormal Weather might conflict with the Student Rules, and Wei Liang suggested stocking up at the Convenience Store to avoid the problem.
  • Lin Yi read the Cafeteria Rules, which listed dangers involving forbidden passages, dark areas, tomato-containing food, Meal Window No. 10, and the Convenience Store Owner.
  • Lin Yi wondered why the Student Rules and Cafeteria Rules gave conflicting instructions about the Convenience Store Owner, and why Security Guards were mentioned only once.
