On the wedding night, Jiang Zhaowei, a researcher on the history of modern law, passed away and became the legitimate daughter of a guilty minister. She was exchanged by her cousin Xie Heng to marry King Jing Pei Xuandu, who had no legs. She tore up the marriage contract in public and made three promises: she would not be an abandoned child, she would not enter the back house, and she would not accept her destiny. Pei Xuandu used her sharpness to investigate old cases in the north, and she used his military power to break the deadlock in the capital; Wen Qiwu handed over the secret certificate of military pay, but Cui Chengli pressed forward step by step with national laws. When the family, family, and marriage were all shackles, Jiang Zhaowei decided to change the dynasty himself.
