Strange words in blood suddenly appeared on the blackboard, and this scene was spotted by Zhang Yan, a passing high school student. The once noisy dormitory building has become a hunting ground for monsters, with dragging sounds and roars intertwined. Evil people take advantage of the chaos to commit violence, and campus ghost stories come true one after another. The dead keep appearing, but their traces are erased by invisible forces. The resourceful Zhang Yan was alert and calm in an instant. He knew that under the shroud of mystery, death was never the end, and he could only survive by being clear-headed and seeking solutions.
