In the year 109, the heroes were divided in all directions, and the world was like the moon cakes shared by naughty children during the Mid-Autumn Festival, one piece at a time, unevenly. However, the ambitions of the kings did not allow for the existence of inequality. Any king would try to piece the moon cake into a whole piece, occupy and rule it alone, and become the only king. At this time, among the southern countries, Leguo, which is located along the river, has the largest land area south of the river, and is based on fish and rice, with mulberry ponds as its base. With the governance of the old Le King Qingming, Leguo has become the overlord of the southern countries. Not only the southern countries have devoted themselves to him, but also Xuanguo, one of the two great powers in the north, has also chosen Leguo. The relationship between countries seems to be strong, but in fact it is the most false. Mutual trust is only based on the fact that each country sends its legitimate son as a pledge to Leguo.
