Urban Doctor Son-In-Law

Li Guanqi, the useless son-in-law who came to the house, had his crotch exploded by a firecracker at the beginning and almost became an eunuch. By chance, he received the inheritance of ancient medical skills. From this moment on, he no longer felt aggrieved, and fought decisively along the way, killing his former enemies and setting foot on the top of the world. What should I do if my mother-in-law looks down on me? He chose to slap her directly and let her reflect on her life! What to do if the enemy dares to play tricks, he chooses to deal with it with one blow, making the enemy frightened when they hear his name! He has adhered to this throughout his life, no matter who it is, he will do it if he doesn't accept it! In terms of medical attainments, I am ranked second, but who dares to be ranked first?
