Li Chengyu, a modern legal officer, pretended to be the puppet emperor of Dayong. On the first day he ascended the throne, he was forced into the palace by the regent Pei Zhiheng. The dignitaries in the palace asked him to hand over the jade seal, but he used a fake edict to counterattack the imperial army, confiscated the nine rebel clans, and recaptured half of the imperial city with his blood. In order to secure the throne, Li Chengyu enlisted the help of Huo Wujiu, the empress who had been wrongly accused, and recruited Xie Guanlan, a capable minister from a poor family, and also dealt with Su Jianshuang, who concealed his former dynasty's identity. The court officials, the border military vassal towns, and the Beiyuan cavalry came one after another. This time, he wanted to let the world know that puppets can also become swordsmen.
