After I Come Down from the Mountain, I Won't Be Able to Deal with the Daughter of a Wealthy Family.

A young man went to the mountains to collect herbs and picked up a son. Later, I picked up a fairy-like stone spirit to be my child's mother. She was invulnerable, but she was afraid of thunder and would crawl under the covers every time there was a thunderstorm. The two of them raised the child together. The mother taught him ancient secrets, and the father taught him medical skills. After the boy grew up, he went down the mountain to make a living. The boy from the mountain village, who had never seen the world, grew up step by step, and finally became the life-threatening envoy of the Japanese slaves. But there is a flaw in that ancient secret technique. You can't be lustful. Once you are lustful, it won't work. There are three of us, one is too kind, one is too pure, and the other is wild, naughty, lustful, and has deep feelings for family and country. The entire wealthy circle was laughing at the young man for being a bumpkin from a mountain village. The young man relied on his family's strength to silence the entire wealthy circle, and in turn they envied him and fawned over him.
