恶魔的尾巴是什么

A young nurse started her shift at an old city hospital. After a strange illusion, the oldest nurse told her that a patient named Moore had entered the hospital a few years ago. His body was completely destroyed after a fire. The doctor operated on Mr. Moore urgently. But no one is willing to help him. Pain and drugs drove him crazy - one night, a nurse went to his room, but his bed was empty. He has no more news. The bell interrupted the story. The phone is from Mr. Moore's room.
