Ultimate Son-in-law

Shen Lang transmigrated into another world as a man who married into a wealthy family. However, the clan saw him as a useless wastrel so they kicked him out. Now he's determined to take revenge on them by finding a wife who's prettier, stronger, and have a more powerful title. But he won't be cultivating his own martial arts skills, because there's no way he's any good at it. Instead, he's going to help his wife become the world's strongest fighter, and let her beat up anyone who dares to stand in his way!
