In the eighteenth year of the Qianyuan year of the Daye Dynasty, Shen Wantang, the daughter of the former censor, was forced to enter the palace as a talented person because of her father's murder and the death of her family. She seems weak and can be bullied, but in fact she is charged with the mission of avenging her father and uncovering the secret of the royal family's murder of the previous princess. The half tiger charm in her sleeve is the key to stirring up trouble in the harem and the court.
The new emperor Xiao Chengyu appears to be ruthless and unkind, but in fact he has hidden obsessions due to the death of his biological mother, Princess Yiwei. He regarded Shen Wantang as a pawn to balance the prime minister and the wise king, and pushed her to the forefront with the help of "a cinnabar mole similar to her biological mother". However, in the process of supporting her from a talented person in the cold palace to a concubine, he gradually fell into the struggle of "use and affection".
When Xiao Chengyu discovered that Shen Wantang's tiger talisman was fake, she put the real talisman into his palm and whispered: "Your Majesty thought that I was a substitute, but you didn't know that you are the checkmate on my chessboard." And he heard this. He chuckled lightly, pushed her down on the dragon chair with his backhand, and rubbed the cinnabar between her eyebrows with his fingertips: "It doesn't matter, I am willing to be your pawn. I will kill all your enemies for you first, and then teach you... What it means to be a true loner."
