The world is like a chessboard, and people are like chess pieces. Deceit and trickery in the imperial court, love and hatred in the pugilistic world, joys and sorrows in the marketplace, are nothing more than chess pieces intertwined on the chessboard, bursting out with sparks of fire. In the Dayue Dynasty, during the Zhaohong era. Rumors circulate among the common people that vassal kings are eyeing the dragon chair in the golden hall, and the emperor summons the heirs of various vassal kings to the capital to study, effectively as hostages. Adapted from the novel "The Heir is Very Fierce" by author Guan Guan Gongzi.
