It has been more than a hundred years since the founding of the Zhou Dynasty. Under the peaceful and prosperous age, undercurrents in the court were surging, factions were fighting, and murderous intentions were everywhere. Today's emperor is proficient in the art of checks and balances, supporting the chief minister of the cabinet Shen Chongwen and the commander of the Jin Yiwei Lu Chenzhou to restrain each other. However, due to suspicion and the worry of having no children, a marriage decree tied these two sworn enemies into in-laws. Shen Qingyi, the legitimate daughter of Prime Minister Shen, is frail and sick but sober and indifferent, taking advantage of her illness to hide her dangers; Lu Yanzhi, the son of Lu Chenzhou, inherits the title, is cold-faced and decisive, and is well versed in maneuvering. This seemingly humiliating and tempting marriage ties two strangers together. They are not only the pawns of the Holy Emperor to check and balance the court, but also the chips in the game between Shen and Lu. The house is dangerous, the court is treacherous, the "fox" pretends to be sick and the cold-faced "wolf", in the thrilling chess game, only by putting aside your sincerity and taking care of every step can you escape the fate of the chess pieces and become the chess player.
