The only words left by his grandfather before his death were: "Don't trust books, trust your eyes." Chen Mo thought he was referring to "The Classic of Mountains and Seas". But when he opened the ancestral book "The Story of the Transforming Snake", what he saw were records written by ancestors of all generations - once every sixty years, someone from the Chen family must disappear. The disappearing person will hear a baby crying late one night, then walk out and never come back. He found the handwriting of the ancestor who left the last message before being taken away. There was only one line on it: "It came to pick me up. It is not a monster, it came to pick me up and go home." Chen Mo chased him to Japan, back to the mountain village, and into the bottomless cave under Yunqi Temple. The cave was covered with human faces - from the Han Dynasty, the Tang Dynasty, and the Song Dynasty. Every face was alive and smiling at him. The old man who had been chasing corpses for hundreds of years walked past him ringing a bell, followed by a row of eyeless corpses. He pushed open the last door and saw his sister Chen Wan - half of her face was covered with animal hair, and one of her eyes had become a vertical pupil. She looked at him like a stranger. Then she smiled and said in a baby-like cry: "Brother, you are finally back. We have been waiting for you for six hundred years." Chen Mo looked down at his hands - on the back of his hands, fine hair began to grow at some point. He suddenly remembered the page that was torn out of his grandfather's diary, the man in his great-grandfather's painting with his back to the mirror all the time, and his own face in all the mirrors since childhood - it seemed that there was always a moment when that face was smiling at him. But he didn't laugh. Who is that laughing?
