Is This World Getting Crazier and Crazier?

Lishan Sanatorium, commonly known as Lishan Asylum, has a few unwritten rules in this place of extraordinary people and spiritual energy. Do not leave your room after lights-out, unless you want to be watched by the still, yet maddening, moonlight; The swimming pool behind the hill is temporarily closed because some indescribable monsters accidentally got mixed in when it was drained; Do not bring dangerous items into the sanatorium, such as magic, cultivation, or superpowers; And finally, stay away from the director's office, or you might get dragged into a nightmare.
