I just secretly slept for a while during class, but when I woke up, I found that the teachers were dead and they were trapped in the class and couldn't get out. Just when the whole class was in panic, a strange system appeared and told them a cruel thing. This was the first screening, and the global death toll accounted for 96% of the world's total.
In the end only one person can survive.
