Yan Suyun, the top master of the demon sect, was surrounded and killed by his elder brother during the power struggle within the sect. He was poisoned and died after fighting. When he was dying, he was saved by a Shaolin monk. When he opened his eyes again, he was back to the time when he was ten years old - being kidnapped by the warriors from the outer courtyard of the demon sect disguised as slave traders on their way to the "demon cave". Yan Suyun, who possesses past life memories and martial arts realm, relies on her knowledge of poisons and calm calculations to kill her escorts, save the children of the Zhengdao family who were attacked, and take this opportunity to live in the Wanzhang family. He hid his strength, practiced secretly, and dealt with the power struggle within the family as a civilian. At the same time, he secretly contacted the mysterious intelligence organization "Afternoon Gate". At the age of fifteen, Yan Suyun had recovered part of her cultivation, easily defeated the top masters of the family, and decided to leave this small world. In his previous life, he was forced to work as a demon and fight for survival. In this life, he has set an astonishing goal: not only to escape the control of the demon sect, but also to become a veteran of the martial arts alliance, to hold power without shouldering heavy responsibilities, to enjoy honor and freedom. A legend that subverts the martial arts structure with reborn wisdom begins here.
