When the classroom clock strikes midnight, the entire campus becomes a forbidden chessboard. Lin Qi, a senior student, stumbles upon a yellowed fragment of a rule sheet while on classroom-cleaning duty, and is drawn into a sinister game of survival on campus. Ordinary classrooms warp into flesh-and-blood labyrinths in the dark. Vanishing desks, shifting blood symbols, walls that breathe: every detail conceals a deadly trap.
“When you finish counting the chairs, the door will open.” Guided by mysterious notes, Lin Qi and his roommate Han Li step into the deadly puzzle of the midnight classroom. When Han Li is swallowed by a writhing wall, when a girl in white from the library’s restricted section leaves behind a blood-red key, and when a diary hidden away in the principal’s office reveals human experiments from thirty years ago, Lin Qi begins to realize that following the rules may not keep you alive, but breaking them will make you part of the rules.
In this cursed school, every mathematical formula is a code for survival, and every ancient book seals away a restless soul. Beneath the flagpole on the sports field before dawn, Lin Qi will find not only a way out, but the bloodiest end to the entire set of rules. As blood-red moonlight shrouds the classroom building, Lin Qi must use the last rule that remains untainted to face off against the “principal,” the one who made the rules, in the underground chamber beneath the library...
This is a battle for survival, logic against chaos. When a classroom is no longer a classroom and rules are no longer rules, only by uncovering the truth that “the rules are lies” can the blood-red curtain that has shrouded the campus for thirty years be torn away.
