As soon as Sang Li transmigrated, her family brought her back from the countryside to take the place of their beloved fake heiress in an arranged marriage.
She practices medicine and cultivates poisons: saving lives is her specialty, while taking them is her side business.
On their wedding night, her scumbag husband wants to pursue a forbidden affair? She strips them both, burns down the bridal chamber, then gives him a single needle that leaves him impotent for life. Then she marries his second uncle and becomes his aunt by marriage!
Her overprotective mother-in-law tries to kill her to cover things up, forcing her to test a poison on herself? One dose leaves the woman paralyzed in bed, wishing she were dead!
The empress abuses her power and sends someone to beat Sang Li to death? Sang Li helps an abandoned consort rise to power, then serves the empress a potion that leaves her unable to bear children!
Everyone is furious at her cruelty and demands that Pei Miao, Marquis of Suyue, divorce her. Pei Miao sneers, "My wife is under my protection! If you bully her, you're insulting me! From now on, anyone who tells me to divorce her had better ask the blade in my hand first!"
A conspiracy leaves him framed by the ruler, betrayed by his brothers and abandoned by his trusted aides. He falls into enemy hands alone. Though he fights his way out, he loses an eye, both hands, and every bone below his waist is broken. His body is irreparably damaged, and he can never have children. He has become a complete invalid.
He writes her a divorce letter, but Sang Li says, "You protected me before. From now on, I'll protect you!"
They know only how ruthless she can be, not how vicious!
That night, poisonous insects swarmed across the capital, and screams rang without end
