The Yunxi State is located in a desert border region, arid and barren. After having ten sons in a row, Emperor Yunwu finally welcomed a little princess, Tuoba You'an. The little princess looks milk-cute and tender. To help her 'poorer than a church mouse' imperial father solve difficult problems such as border food and forage, refugee famine, and court skepticism, the three-year-old tot plants rice, plants strawberries, and makes spicy and sour shredded potatoes. Emperor Yunwu transforms in a split second from 'hacking people on the battlefield' to 'holding his daughter to attend court session'. The entire court has only one principle: whatever the daughter says is always right, and even the rivers and mountains can be given to her.
