Collective disappearance. Zhihu, the novel/kloc-Dormitory at 0/4 o'clock, ends with Yang Re as the protagonist. Reading Zhihu's novels, I know that the dormitory that ended at 14 o'clock is a collective disappearance. The novel is about someone who sent a message anonymously in the class group. Don't open the door for the person checking the bed and don't make any noise. At this time, it is two o'clock in the morning, and the bed inspection has begun.
