Son-In-Law of the Medical Saint

Eight years ago, Mr. Chen died to save Shi Lei. Before he died, he hoped that Shi Lei could marry his daughter. In this way, Shi Lei became a door-to-door son-in-law and was abused by his mother-in-law and wife for 8 years. In the end, he was stabbed to save his wife. He thought he would die, but he unexpectedly received the inheritance from his ancestors, and his useless son-in-law turned into a little expert in medicine.
