After the Rebirth of Poison, Sa Exploded

In her previous life, she was the legitimate daughter of the Duke of Zhenguo. She was madly in love with the prince, and her heart and soul were taken out of her. However, she was stolen from her by her concubine and was abandoned by the prince like a pair of worn shoes. A glass of poisonous wine, and everyone in the family was killed. She died with hatred, and her soul returned to three years ago. When she opened her eyes again, she was a life-seeking evil ghost crawling back from hell! Poisoned into the bone marrow? She solved it with her backhand! Is the concubine hypocritical? She tore the white lotus with her hands! The prince is affectionate? She kicked him away and ruined his reputation! Everyone in the world laughs at her as a good-for-nothing legitimate daughter whose life is as thin as paper. But little did they know that she had returned from the fire, was an expert in medicine and poisoning, and had unparalleled scheming. Fight concubines, tear up scumbag husbands, protect your family, seize power, and make waves all over the capital along the way! One day, the powerful and cold-faced prince blocked her in a corner and said in a hoarse voice: "Princess, don't be too tired. I will help you torture the scum, and you will only be responsible for the beauty." She raised her eyebrows and sneered: "Your Majesty, defeat me first before you talk."
