Horror Game: I Spent the Night in a Cemetery

Occasionally, a "death-killing demon" appeared in the classroom, and people died one after another. In order to survive, we can only do what it says and complete tasks one after another. For example, carrying corpses in the morgue, staying overnight in the cemetery, tomb robbing expeditions, corpse refining, etc. These tasks are all tasks issued by the deadly demon. I don't know how long I can survive... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
