Shen Zhiwei, the sickly and frail son of the Marquis of Jingan Mansion, was "joyed" by being married to the notorious Zhenbei General Xiao Yibei, which everyone said was a life-threatening talisman. On the wedding night, Shen Zhiwei, who looks sick and broken, and pitiful, and Xiao Yibei, who is cold and guarded, hide their edge. When the fate of food and grass in the north came to be robbed, Shen Zhiwei's incredible "scrawled river map" first emerged and stirred up the chess game. However, the unexpected discovery of the bloody corpses of palace residents in the abandoned well of the General's Mansion completely shattered the pretense - this "happy occasion" was actually a borrowed-knife murder plot carefully planned by the queen. Shen Zhiwei, who was chronically poisoned and struggling to survive, and Xiao Yibei, who was trapped in a political vortex and faced catastrophe, were forced to form an alliance amid suspicion and temptation. Two "chess pieces" whose lives were hanging by a thread, in order to survive, overturned the magnificent bloodthirsty chessboard, and embarked on a thorny road to jointly stir up the chaos in the court and fight against the poisonous schemes in the palace.
