Haijing University, a top university with a calm surface, secretly circulates chilling "weird stories about campus rules". "Don't walk alone by Weiming Lake after twelve o'clock at night", "Never enter the last classroom in Teaching Building No. 3 After sunset"... These are not only legends, but also taboos that can lead to death if touched.
The transfer student Silence accidentally broke into this abnormal area shrouded in "rules" with his cool mind and meticulous logic comparable to a machine. Here, he met Xia Zhiyao, who was exploring alone to find out the mystery of his brother's disappearance. Her innate intuition can warn of danger, while his rationality can analyze the rules to find a way out. When classmates disappear or die mysteriously after breaking the rules, they realize that they must join forces.
On this campus dominated by invisible terror, they not only have to struggle to survive, but also uncover the ultimate secret behind the rules - is it an evil spirit, or is it some kind of higher-dimensional existence that has turned the entire university into a cold hunting ground? The truth is far more terrifying than the most terrifying rumors.
