Excellent Doctor Son-In-Law

I am a son-in-law, but a son-in-law in the mountains. His poor diet is a bit embarrassing to his peers. He faces poor mountains and ravines all day long, and he has no chance of getting fancy cars and mansions. Until one day, He Changan suddenly received the inheritance of the Human Emperor, possessed by Fuxi's Eight Treasure Turtle Luoshu, and was proficient in medicine, divination, astronomy, geography, and martial arts. He Chang'an, who possesses unparalleled magical powers, officially came out of the mountain. Now he can call the wind and rain, travel across the city, and ask the vast land, who dares not to obey?
