On the first day Lu Ran, a freshman in high school, entered Mingchuan Middle School, he learned an astonishing secret from his senior Su Ming: This school built on a mass grave has countless strange rules hidden in it - the girl who is always smiling in the cafeteria, the "dormitory manager" who knocks on the door at midnight, the human-shaped grass marks on the playground... Every rule is a warning in exchange for life.
As roommates broke the rules and disappeared mysteriously one after another, Lu Ran discovered that the school was using the students' yang energy to suppress the yin energy. If you want to survive, you must find a way out between the rules. In the end, only Lu Ran escaped and ascended to heaven, revealing the shocking secret of Mingchuan Middle School.
There is only one survivor, because he is the only one who never believed in this school.
Welcome to watch!
