Su Changge, the legitimate daughter of a military family, is unjustly convicted and exiled to Mobei. In a desperate situation, she uses her ingenuity to collect water in sand pits, saving lives. After arriving at the place of exile, she leads the people in resisting sandstorms and reclaiming wasteland to survive. Using a family-inherited atlas, she digs wells and canals, cultivates barren land, and engages in commerce. Unafraid of oppression by the powerful or conspiracies and false accusations, she stays true to herself, overcomes every crisis, and builds her own enterprise. Ultimately, she brings peace to the chaos in Mobei, takes control of military and political power, and rises to become a formidable woman who establishes order across the great desert.
