The man said that only one person could come out alive from that old school, as if telling us to fight and kill each other. Immediately, everyone tried to survive, killing each other.

But, there are also people who avoid fighting and hide alone because they are afraid. but, there were also some of them who just watched the deadly battle as if they were not interested in such things and were just observing the situation.
