Sister-In-Law, Don't Be Afraid, I'm Invincible If I'm Not Stupid

A rural youth has been pretending to be stupid for three years, and everyone dares to step on me. That night, I received the inheritance of the medical fairy. The first thing I did when I woke up was to take care of my wife, kill people, and collect debts. From Qingniu Village to the wealthy sect, from the underground black market to the Kunlun Fairyland. To protect my sister-in-law, I will not take a step back; to find my mother, I will kill Kunlun with one sword.
