This Killer Is Poisonous

[Villain Heroine] Zhinan is the super villain in this sweet novel. In the end, she was hacked to death with a knife. Her life was spoiled, and she said that I don't care. When Ye Sangluo saw her for the first time, he stopped breathing. After all, she was the one who killed her. But after taking a second look, Zhinan's villain image instantly collapsed. "Is this mentally retarded person in front of me a villain? Damn, just make fun of her!" Whatever you can't do, be the first to escape. Eat nothing without leaving anything, for fear of losing your mouth. But in the end, after she found out that she was killed once by her male partner, her mind became a little bit funny and she started to become smarter. Sometimes she likes the male protagonist, and sometimes she loves the second male lead to the point where she kills people at every turn, which is very bloody. She even became a lot colder towards her master, changing from a talkative person to a cold and aloof lady. Later I found out that she was really smart. Moreover, her master is an old naughty boy who always has four maxims on his lips, "A young man does not know how good his aunt is, and mistakes a girl for a treasure; a young man does not know the fragrance of soft rice, and mistakes his youth for transplanting rice." (PS: The heroine is the villain, and she is against almost everyone, so don't criticize her!)
