In the previous life, Shen Wantang, the concubine of the Hou family, was poisoned to death by her aunt and uncle during the wedding ceremony. When she woke up after rebirth, she found that she was bound to the "blackening value monitoring system" - she must make her enemies hate her to the bone in order to survive. She put laxatives into her aunt's tea, cut up the tyrant's dragon robe, and called him a coward in public. Unexpectedly, the tyrant not only didn't get angry, but instead doted on her more and more. The blackening value dropped again and again, and she was getting closer and closer to death. Until she discovers that the tyrant also remembers his past life - and that he would rather die than hate her. What's even more shocking is that her nemesis, the Crown Princess, is actually her long-lost sister. The sisters join forces to expose the shocking conspiracy of the eunuch who has lived for three hundred years. This time, she is no longer alone.
