The ultimate ghostly school instance with the top five fatality rates suddenly opens. As a novice, Lin Luan is forcibly dragged into this unsolvable death game. The old campus is shrouded in gloom year-round; the ceaselessly echoing bell tolls are the only countdown signal, and with every drop, it means someone is about to sleep forever. There is no lucky clearance here, only cold, unsolvable rules and cruel plunder. Veteran players calculate every step and kill each other maliciously; newcomers entering the game are prey right away. Kindness is the most fatal flaw, and backing down will only make one others' clearance chips. Blood-red eyes lurking in the dark firmly lock onto every intruder, and eerie murderous intent is hidden in every corner of the teaching building.
