Gu Zhiyu, an abandoned daughter of the Duke of Zhenguo, was thrown away by her aunt in Zhuangzi for three years in the name of "praying for blessings".
On the first day back home, bandits intercepted and killed them - she smiled and brought out the poisoned wine, and all twelve of them were killed.
The aunt's mother poisoned the other party's cat in a chronic way - she poisoned the other party's cat and responded with a bowl of "tonifying soup": "Stew it according to the recipe you taught me."
From then on, those who bully her will be killed; those who frame her will be killed; and those who poison her will be killed. It doesn't rely on rebirth, time travel, or men, it all depends on a delicate heart with seven orifices and a superb poison technique.
The aunt's mother vomited blood, the concubine's sister died, the general's uncle was demoted, the regent was defeated... Every move was her own decision.
Oh, by the way, there is also a prince named Chu Yu who always wants to "marry" her.
