The male protagonist was originally just a humble ordinary person, far from rich. He got together with the female protagonist because his grandfather once helped the Lin family. After the two got together, his wife's thoughtfulness and his own inaction made him feel useless. Because his grandfather was ill, he accidentally received the inheritance from a mysterious man. At this point, he has medical skills, a pair of eyes can see all the illnesses of time, and a silver needle can whiten flesh and bones.
