Wen Su, an ordinary college student, opened a "Collection of Campus Horror Stories" and woke up standing in front of the boys' dormitory room 404 of Guiming No. 1 Middle School.
There are six rules of work and rest posted on the back of the dormitory door: turn off the lights at eleven o'clock on time, do not get out of bed after turning off the lights, do not go to the toilet, and never answer when someone calls your name under the bed.
This is a Chinese-style boarding high school, and it is also an infinite copy world composed of nine campus ghost stories. Dormitories, classrooms, canteens, libraries, evening study halls, exams, offices, playgrounds, graduation ceremonies... Every familiar campus scene hides a set of unreasonable but must-obey rules.
The deceased will disappear from the copy, and everyone will gradually forget his existence, leaving only unexplainable traces such as beds, rosters, soap prints, and blank seats.
Wensu must clear nine dungeons and unlock the story collection catalog before he can return to Blue Star.
But as one strange story was revealed one after another, he gradually discovered that the collection of stories had not chosen him randomly. Guiming No. 1 Middle School is not a school that has nothing to do with him.
