Ye Yutong, a modern social worker, was turned into cannon fodder after a car accident after leaving her job. She used space materials to take her original owner's family to escape famine, and moved forward with the support of Li Yunze, settling down in the mountains of the northwest. Later, Li Yunze revealed his identity as the prince, and Ye Yutong helped him seize power. The two rescued the refugees, strengthened their troops, and finally put down the rebellion, stabilized the society, and created a peaceful and prosperous era.
