Xie Zhao, the deputy general of the Zhenbei Army, was falsely accused of collaborating with the enemy and his entire family was executed. He was trapped in the enemy camp but was hiding in secret. When he led the enemy's cavalry back to the imperial city, he discovered that the evidence of treason was actually forged by the new emperor and the female official Jiang Si. The real emperor Lu Chenge, who lives among the people, appears and exposes the centuries-old blood curse of the royal family. Pei Jin's secret files, Mu Wufeng's cavalry, and Jiang Si's stars were all used as counterattack pawns. Xie Zhao didn't want to be emperor, he just wanted to clear his grievances; Lu Chenge didn't want to ascend the throne, he just wanted to burn this man-eating dragon chair.
