The Most Helpless Son-In-Law in History

Li Lang, the director of the mental hospital, traveled to Great China with thirty-seven mentally ill souls and became the son-in-law of a local landowner. I want to be a father from the beginning. What to do? Li Lang decided to find a different restaurant. I will make some small money, make some inventions, and train my wife to be the best in the world. If anyone dares to mess with me, I will let my wife slap him to death. I want to be the king's man, the most handsome man in history!
