Chu Yingning is disguised as a vicious female supporting character in a sweet novel, but the system task bound to her is not to conquer the male protagonist, but to cure the love brain of the original heroine Mu Jiaojiao.
Mu Jiao is the daughter of destiny, but she fights for her three male partners. Every time she falls in love, it triggers catastrophes in the world of cultivation: spiritual veins dry up, monsters riot, and sects are destroyed. Chu Yingning was forced to go around to save the situation, delivering the Heart-clearing Pill, throwing the soul-suppressing flag, and blocking the Ten Thousand Sword Formation, and was so busy that her feet never touched the ground. But Mu Jiaojiao cried: "Why do you stop our vigorous love!"
King Xuanji Mo Xuanji watched with cold eyes. It was not until he saw her seriously injured and vomiting blood while protecting the mortal city that he realized that this woman really only wanted to protect the common people. He took her into his arms and said, "You save the common people, and I will protect you." From then on, he slashed the Heaven's Secret with his sword and accompanied her into death. The immortals taunted her and smashed the Heaven's Secret Monument with one sword: "My king's woman is not the one to be judged by Heaven."
In the end, Mu Jiaojiao opened the blood sacrifice formation, Chu Yingning burned the source of the system to repair the way of heaven, and Mo Xuanji tore open the formation eye with his bare hands and entered half of the godhead: "If you want to cure the love brain, you must live for me to cure it." Three hundred years later, at the Nine Heavens Palace, he held her hand and reviewed the memorial: "Whose love brain do you want to cure tonight? I will demolish his marriage palace."
