I am the king in The Unwanted Son-in-Law

A handsome man, who became the ruler of wealth by defying social norms and living in his in-laws' house with his wife, was kicked out of the house for being deemed useless. As a result, he worked hard to find a stronger, more beautiful, and more powerful woman to be his partner. With his new woman, he settled in his in-laws' house once again. It's impossible to practice martial arts, impossible to practice martial arts in this life! One can only sustain their life by eating rice, not practicing martial arts! I want to train my wife to become the number one in the world. Whoever dares to provoke me, I will ask my woman to beat them to death!
