Rule Horror: The Rules of Yongshan No. 1 High School

Transfer student Lin Yan arrives at Yongshan County No. 1 Middle School and discovers that the place is ruled by a bizarre school regulation: after lights out, students must not leave their beds. Anyone who breaks the rule will receive a terrifying mark, and after three violations, they will be dragged into the "Principal's Office for Reconditioning." To graduate alive, he must uncover the truth behind the human experiments that turned students into "perfectly obedient subjects" eighty years ago, and destroy the source of the resentment before the rules consume him.
