On a snowy night ten years ago, Su Tang was abandoned in a mass grave by her loved ones, and no one cared about her poisonous body. Ten years later, she returned in the name of the Poison Doctor Saint, and overnight she caused everyone in the Su family to be poisoned and begging for an antidote. Pei Yuan, the young master of the Seven Kills Hall, was ordered to assassinate her, but instead he was planted with the seven-day soul-breaking Gu, and has been entangled with her ever since. But the road to revenge is far more bloody than imagined - the conspiracy of her brother Su Mingyuan, the surveillance of the genius doctor Xie Yunzhi, and the royal secrets behind her own life experience... When the begging turned into conspiracy, Su Tang sneered: Poison can kill people, and it can also read people's hearts. This time, she will let everyone who has betrayed her taste a taste more painful than death.
