Gu Xiyuan cut off the entanglement with the prince Xiao Jinchen and married the King of Yan, Xiao Xun. Shortly after the wedding, Xiao Xun went on an expedition, but was ambushed by Xiao Jinchen. After Xiao Jinchen ascended the throne, he threatened Gu Xiyuan, who was pregnant with King Yan's posthumous son, to enter the palace because of the safety of the Jiang family. Gu Xiyuan tolerated the plot and teamed up with King Yan's biological mother, Concubine De, to deal with Wan's concubine Gu Qingwan, Concubine Min, and the Queen Mother's enemies. They used the birthday banquet to reverse the frame and eliminate the harem rivals. She pretended to collude to rebel against the King of Qin, and used the King of Qin's hands to kill Xiao Jinchen, then put down the rebellion of the King of Qin, and liquidated all the enemies in the Pingyang Hou Mansion. In the end, Gu Xiyuan supported his son Xiao Qian to ascend the throne, took charge of the government as the queen mother, and avenged the bloody death of her husband.
