I recommend the novel "The Village Peach Luck Doctor" to you. The male protagonist, Chen Dong, is a fool. He has a sister-in-law and sister who takes good care of him. When he was in school, his sister-in-law was harassed by a rogue. He tried to save her but was persecuted. By chance, he obtained the inheritance of the Supreme Mystic Fairy, medical skills, and unparalleled martial arts. After his sister-in-law asked him for help, he had a wonderful story. I hope you like my recommendation. Muah ~
