Pei Ju, an inconspicuous farmer in Jiang County during the day, wipes the iron talisman of the former Black Eagle at night - this surviving descendant of the Black Eagle Army has been dormant for many years, waiting for the storm to rise again. Yu Lingshuang is the legitimate daughter of the Yu family in Youzhou. Although her father has no official position, he controls the golden trade route connecting northern Xinjiang. Her uncles were either Youzhou generals or held important positions as state shepherds, but she grew up in caravans and military camps and developed her skills.
In troubled times, he used her family's business route to secretly communicate with soldiers, and she made good friends with her uncle's military connections. From the grass in Jiang County to the top of the court, the couple worked together step by step - he taught her tactics and tactics, and she helped him conquer all forces. They used gold and silver to clear the way and established their power with iron and blood. When they faced each other at the peak, they finally saw each other's true appearance. Facing the edict to abolish her son's position as crown prince, she put the tip of her hairpin against his throat and said in a voice as cold as ice: "Pei Lang, you taught me that there is no mercy in troubled times. Why did you forget when it was our child's turn?"
