During the Dajing Dynasty, the world was initially settled, and various forces were undercurrent. There is a hidden medical clan in southern Xinjiang - the Chuli clan. They have passed down the art of medicine and poison from generation to generation, and guard the "Holy Spirit Grass" that can bring the dead back to life. However, due to a sudden murder twenty years ago, the Chuli clan was almost wiped out, leaving only a pair of young twin sisters. The elder sister Su Wanyue was sent away by the elders of the Chuli tribe to live among the people; the younger sister Su Ruoxue was taken away by the enemy and disappeared.
At the same time, internal disputes continued in the Dajing royal family. Although the current prince Xiao Chengyu is the crown prince, he is isolated and helpless in the court due to the early death of his biological mother. He is deliberately suppressed by the emperor Xiao Mingxuan and fights openly and secretly with his brother Ning Wang Xiao Chengheng. Xiao Chengyu's maternal clan, the Han clan, was once the founding hero of Dajing, but due to involvement in a rebellion, the entire clan was wiped out. Only Han Ruoxi, the legitimate daughter of the Han clan, escaped by chance, which became Xiao Chengyu's obsession.
