At twelve o'clock every night, a pale face is posted outside the window - blood-red eyes are staring, and the corners of the mouth are grinning from the corners of the ears. Yan Bo screamed and called the police. The police came, but there was no one outside the window. His roommate scolded him for being crazy. It wasn't until the next day that his roommate's body was hung outside the window, with a human skin mask peeled off his face, revealing a smile that was exactly the same as that face... Yan Bo finally understood: he was not going crazy, he was born with the ability to "see" the most disgusting existences in the world of supernatural perception - those things lived on human fear, and he was their chosen host. At twelve o'clock tonight, when that face appeared again, Yan Bo held up the bronze mirror he had just picked up from the sea of blood in the corpse mountain and licked his teeth: "Have you eaten enough? Next, it's my turn to 'reverse'."
