Lu Zhao, a sickly scholar who had been dormant for many years, was "buried in a sea of fire" in a well-planned fire and has since escaped. With his skinny and sickly body, he set up a shocking chess game and singled out the intricately connected aristocratic families. When everyone thought he was just a chess piece that could be discarded at any time, he took the chess piece as a blade and vowed to pierce through the decaying court and those hypocritical smiling faces. In this game, with blood as ink and bones as pen, the game is about the future of Dayu.
