Yin and Yang are overturned, and the underworld invades the yang world. The Yin soldiers took advantage of the passage and prepared food for the living. Shen Yan, who was fishing for the Yinmen, cut his wrists to get blood, but his soul was eaten by the evil spirit instead; Shen Yan, who came through the soul, swallowed the black blood and shouted: "System, twenty-three years of Yin life stud. From then on, he swallows ghosts and eats evil spirits, and then he lives forever.
