Is the World Getting Crazy?

Lai Shan Sanatorium, commonly known as Lai Shan Lunatic Asylum, has several unwritten rules in this place of outstanding people. You are not allowed to leave the ward after turning off the lights, if you don't want to be peeked by the quiet and crazy moonlight; The swimming pool in the back mountain was temporarily closed because some unspeakable monsters accidentally got mixed in when the water was released; Do not bring dangerous items into the nursing home, such as magic, cultivation or superpowers; The last thing is, don't get close to the dean's office to avoid being involved in the nightmare.
