Chaos broke out in Yongjia, and Bingzhou broke out at night. Xie Changge, a modern civil engineering doctor, passed away as the 17-year-old daughter of a partial branch of the Xie family. Her father and brother died for the country, so she took 300 remnant soldiers and half a piece of tiger talisman to seize the pass and enter Taihang on a snowy night. Lack of food, lack of people, and lack of trust, she used engineering as a blade and power as a shield to build canal transportation, fire cattle, and set up farmland. She recruited refugees, female generals, and tamed the Black Mountain Crow Army in the cracks between Hu and Han. From the time she abandoned her son to the Duke of Yan, she rejected the throne three times and served as regent for ten years, leaving only an unmarked tablet and an iron halberd. In troubled times, all living beings are sons. Xie Changge has no regrets about being a son, and finally writes an unknown history of the world as a woman.
