There is an undercurrent surging in Dayin's court. Su Wan, the silly third lady of Shangshu Mansion, fell into the water and was shocked to see the exquisite inner orifice. She pretended to be innocent and made her calculations crackle - her sister-in-law's marriage was a chess game, her stepmother's vicious plan was a stepping stone, and even the aloof Ninth Five Emperor was just a pawn in her scheme of power. Everyone knows that she is as stupid as a pig, but they don't know that she has already weaved a huge net that covers the sky, and will catch all her enemies when the time is right.
Until she met Xiao Jingheng, the idle prince who always ate her sweet-scented osmanthus cake in the imperial garden. He shielded her from open and secret arrows with a playful smile, but caressed her broken hair on the temples when no one was around: "Little fox, if you keep pretending, your secret will be exposed." Su Wan was shocked to realize that this seemingly cynical uncle had seen through all the disguises earlier than she did.
When the affairs of the court and the secrets of the back house are intertwined, when the Machiavellian who pretends to be a pig and eats the tiger meets the Xiaoyao King who hides his clumsiness and defends his foolishness, who is the real chess player in this game where the world is the chessboard? Let's see how Su Wan stirs up the chaos in the court as a woman, breaks through the fog together with Xiao Jingheng, and walks a path to the sky in the turbulent and prosperous age.
