Jun Yuzhao, young head of an ancient martial arts clan in the 30th century, transmigrates one day into the body of Lin Yuzhao, an ugly, useless girl from the Lin family in Zelan City, Qingcang Province, Dongsheng, whom everyone can bully.
The Lin family plans to marry Jun Yuzhao off to an ugly Poison King in exchange for a chance for the family's legitimate daughter to advance her cultivation.
Jun Yuzhao is a master of poison. If they call me useless, I'll repair my meridians. If they call me ugly, I'll restore my exquisite beauty. Whoever dares bully me, I'll kill the Poison King and wipe out the Lin family. I'll become a disciple of the Cangqiong Palace and turn the entire Wuwei Continent upside down.
She never lets an offense go unanswered. Her creed is: If you leave me alone, I'll leave you alone. If you cross me, I'll repay you a thousandfold, ten thousandfold.
Whenever Jun Yuzhao thinks revenge is about to drive her down the path to becoming a demon, a strong hand always reaches out and firmly pulls her back.
An exquisitely beautiful girl with peerless talent, a master of poison who never lets an offense go unanswered * A principled, upright, taciturn second senior brother who remakes his Daoist heart and dotes on his wife without limit
