After the Engagement Was Broken Off, the Concubine of Kefu Tore Apart the Whole Family of the Scumbag Man

With a piece of paper to cancel the engagement, I went from being a royal daughter to being despised by everyone. Desperate, I caught up with the sick prince of an enemy country who was sent as a hostage. They laughed at us as a disaster star paired with a loser, a perfect match! But later on, I became a master of medicine and poisoning. I tore the white lotus with my hands and trampled on the scumbag; Everyone was dumbfounded: Where is the promised waste? The sinister man held me in his arms and chuckled: "Madam, it's time to go to court and overthrow the country."
