In order to break off the engagement, the prince Xiao Jing sent Xie Wang, Pei Ji, and Shen Qingzhou to seduce his "fiancée" Zhao Lingyi. Unexpectedly, the marriage contract was originally between the eldest sister Zhao Lingyi and the prince. She took advantage of the situation and took the three of them as her own, while making fun of them and plotting secretly. When the prince discovered the truth and wanted to break off the engagement, the three of them actually fought for Zhao Lingyi. In the end, with the support of his sister who held military power, Zhao Lingyi no longer concealed his ambitions, and with his three right-hand men, he pointed his sword at the world and decided to rebel and seize power.
