In her previous life, Xu Jingyang, the legitimate daughter of the Xu family, disguised herself as a man and enlisted in the army in her father's place. After ten years of bloody battles, she earned glorious military honors. Yet, after faking her death and returning to the capital, her parents and younger siblings joined forces to steal her achievements. Reborn on the very day of her return, she cuts off her family ties and launches a step-by-step counterattack, leveraging the power of the Grand Princess, imperial authority, and Prince Ning, Xiao Heye. She exposes the hypocrisy of the fake heiress, Xu Rouzheng, and forces the Duke of Weiguo to reveal the truth behind his feigned injury, his evasion of battle, and his scheme to send his daughter to war in his place. Using military strategy to fight domestic battles and ironclad resolve to shatter conspiracies, she ultimately reclaims the title of General of the Divine Strategy Army before the imperial throne. At the end of the snowy winds, Xu Jingyang and Xiao Heye stand side by side, becoming the masterminds who control the fate of the realm.
