AnalogHorror: Rule Kaidan 4016

[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!]
