Su Xiaoman grew up secluded in the mountains with her family. Simple and innocent by nature, she came from a family of healers but had no interest in practicing medicine, preferring to play with poisons. To protect her, her elders fed her medicinal remedies, and over time her blood gained the power to neutralize all poisons. One day, while playing, she met Fang Lingye, who had come to the mountains to seek medical help from her elders. When his request was refused, Su Xiaoman offered to help. But after she used her blood to detoxify Fang Lingye's mother, Fang Lingye took advantage of her weakened state and poisoned her. He then handed her over to his father, who had gone mad from experimenting on human bodies. Su Xiaoman was eventually tortured to death.
After her death, Su Xiaoman transmigrates into the body of Shen Qianhua, the legitimate daughter of the Shen family in an alternate world. The real Shen Qianhua was an unrivaled master of medicine, hailed by the local people as the “Medicine Immortal.” Later, when Mu Feileng comes to seek treatment, the head of the Shen family makes him an offer: if he wants Shen Qianhua's help, he must marry her. On the day Shen Qianhua is to be married, her younger half-sister Shen Liuxuan, consumed by years of jealousy, cruelly poisons her. By a twist of fate, Su Xiaoman is reborn...
It's pretty good-looking, and the female protagonist is quite innocent.
