Working overtime late at night, Lin Mo was involved in a soul-binding thriller. Abandoned campus, bloody rules, scissor-wielding demons, weird reading sounds... "No walking in the corridor after ten o'clock in the evening" and "Don't approach when you hear the sound of reading". Behind every rule is a fatal trap. The mobile phone becomes the only light source, points are exchanged for life, and the key to the dean's office is the only hope to pass the level. When the kid in school uniform drags scissors and approaches, and when the white-clothed phantom wanders in the darkness, he discovers that there is a secret more terrifying than death hidden at the end of this survival game. Suspense lover Lin Mo, can he survive until dawn in the abandoned Thirteen full of ghosts?
