Shen Jinglu was originally a talented and beautiful princess. Due to the change of imperial power and the injustice done to her mother's family, she was forced to disguise herself as a man and be sent to Beidi as a hostage. In that bitter cold place, she had no golden fingers or cheats. She only relied on her extraordinary forbearance and ruthlessness to secretly conquer the wandering militia generals. At the end of the ten years, she returned with her iron cavalry and bloodshed. The imperial brother who once trampled on her, the beloved concubine who poisoned her mother and concubine, and the father who regarded her as an abandoned son, all fell into destruction step by step under her calculations. She wants to reveal her identity in public, ascend the throne as a woman, and change the world.
