My name is Wei Zheng, a makeup artist at a funeral home. After five years of putting makeup on dead people, I have seen various ways of death, but the body that was delivered three days ago was different. The man had no external injuries, his expression was calm, and he even had a smile on his lips. But in his right hand, he held a piece of paper that said: Don't look back. I put the note in my pocket and something happened that night. First the lights in the funeral home went out, and then the drawers of the refrigerated cabinet popped open on their own. I saw the dead man, standing at the end of the corridor, smiling at me. Now I know that there is something hidden in this city. They feed on rules and make a living by killing people. And I am the only one who can see them.
