Gao Yifan, a young monk at the bottom of the world of immortality, died on the spot after failing to escape the tribulation, but his soul plunged into modern society and became the most useless son-in-law of the wealthy Song family. With no cultivation and no backing, facing the cold eyes of his mother-in-law, the disdain of his fiancée, and the humiliation of his brother-in-law, Gao Yifan's only remaining "special ability" is his own mouth—as long as he can't help but say something in his heart, it will come true in reality!

Li Yunfeng set up a trap step by step, and Gao Yifan slapped him in the face every day. In the end, what awaited Li Yunfeng would be the bitter fruits he had planted with his own hands. What Gao Yifan didn't know was that the ability of his mouth seemed to involve a secret older than the world of immortality...
