[True to its genre: a creepy, rule-based horror story, highly refined and quality assured, but prospective readers seeking a thrilling experience should think carefully before proceeding.]
In order to secure a substantial university life experience grant, Lin Yi and his roommate registered to attend a suburban university.
A seemingly ordinary but slightly unsettling set of student regulations;
Strange signs in front of the buildings and seemingly normal building rules;
Mysterious figures threading through the campus under abnormal weather conditions…
As the experience unfolded, more and more bizarre people and events emerged. To survive and leave the campus, Lin Yi had to navigate on the edge of the rules…
[Note: The logical chain of this book was deduced by the author before it was written, forming a closed loop. All rules serve as clues, and all the inconsistent, mysterious occurrences will receive scientific (or quasi-scientific) explanations. There are no supernatural events or related phenomena (just kidding), you are welcome to try reading it!]

AnalogHorror: Rule Kaidan 4016

"Song Rentou entered the school on the afternoon of the 2nd last month, participated in the roll call at 9 PM that evening, and then consistently attended roll call for the next three and a half days, but was missing for two days, only re-signing in on the morning of the seventh day before leaving the school area that afternoon."


"It seems normal, but the fact that he didn't sign in for those three and a half days is a big problem..." Tian Bufan mused.


Lin Yi nodded and said, "Yes, but unfortunately, the class teacher at that time also seemed to have no knowledge of his whereabouts."


"That's a hasty conclusion," Tian Bufan countered, "The class teacher definitely wouldn't tell you all the information; she only shared Song Rentou's attendance records because you provided the clue about the note."


"As soon as you left the office, she probably checked some records or something."
