One sentence summary: On the surface, the legitimate daughter of the Prime Minister is frail and frail, but in fact she is a black lotus who works hard every step of the way. Under the siege of her vicious stepfather and her scheming concubine, she joins hands with the evil prodigy to take revenge, and finally seizes power and tramples all enemies under her feet.
Main plot: I, Xie Zhiyun, the legitimate daughter of the Prime Minister of the Xia Dynasty, was "frail and sickly" since childhood, and was regarded by my stepfather and concubine as a soft persimmon who could be manipulated at will. They poisoned my mother, plotted against my grandfather's family property, and used me as a pawn to cling to the powerful. They thought they were raising a lamb to be slaughtered, but they didn't know that beneath the sick and weak skin was a heart that was already blackened and worried every step of the way. I used myself as bait to lure the enemy's proton Pei Yanzhi into the situation. He is the most dangerous pawn in my plan and the only sharp blade I can hold on to. We use each other, test each other, dance together on the tip of the knife, and fight back in desperate situations. When the conspiracy between my stepfather and my mistress was torn apart by my own hands, and when all the people who bullied me, humiliated me, and betrayed me fell on their knees, they discovered to their horror that there was never any weak legitimate daughter, only the chess player who crawled back from hell and wove the web with his own hands.
