Three years ago, Shen Jue, the literary champion, abandoned his literary career and took up martial arts due to an injustice against his family. He transformed into a royal guard and walked in the darkest corners of the capital. An embroidered spring knife and a pair of eyes that can see through people's hearts. He used the queen of the guilty minister as a pawn to stir up the struggle for the crown prince of the Ming Dynasty. In the layers of the Dongchang, the cabinet, and the vassal princes, he avenged the injustice and shed blood for the family. In this chess game of power, he is both a pawn and a chess player.
