Three hundred years ago, she was the extremely poisonous master who single-handedly established the Poison Sect and made Kyushu fearful; three hundred years later, she awakened in the body of Shen Qingwan, a useless village girl who was ruthlessly divorced by the genius of the Xuanhu Sect and whose meridians were severely severed. Seeing that the sect he created casually back then was now being falsely accused of heresy, the max-level boss just wanted to sneer: These are all leftovers from my past!
Faced with the village chief's forced marriage and the quack doctor's disregard for human life, Shen Qingyuan relied on a drop of "Netherworld Blood" from her previous life to break through the situation. Using blood as a guide and poison to fight poison, she can cure terminal diseases that others cannot cure, and cure strange poisons that others cannot. From a mysterious wild doctor in the black market in the countryside to a peerless poison doctor famous in the capital, she worked step by step to slap the hypocrisy and orthodoxy of Yaowang Valley in the face and reshape the rules of medicine.
However, with the treatment of the powerful regent Xiao Xuance who was infected with a strange poison, a conspiracy of "alienation epidemic" sweeping the entire Dayin Dynasty gradually emerged. Her blood of all forms is the only antidote, and his yang energy is the anchor that keeps her emotions from being completely wiped out. The two of them joined hands to fight against the abyss while pulling each other's antidote.
When the truth of three hundred years ago is revealed and the former Poison Lord returns, who has the final say in the world of medicine?
