Cai Chengran was originally a young man whose spiritual roots were abandoned and even the sect's handymen were despised. However, in a certain death situation, he broke through the ancient healing spiritual veins and was able to exchange injuries for opportunities and break through the realm with pain. Gao Shiqing, who is responsible for the secret of the sect's power struggle, appears to be cold and distant, but in fact, if he makes one mistake, he will be doomed. From using each other to redeeming each other, the two of them forcibly carve out a path that belongs to the weak against nature in the midst of the sect's struggle for the throne, the undercurrent of demon disaster, and the life-and-death counterattack.
