Holy Night Continent. The six kingdoms of Northern Zhou, Xiyue, Nanyue, Nanlin, Dongsheng, and Dongzhao divided the world into six parts.
The Northern Zhou Kingdom was composed of nine tribes. It was located in the north and had the largest territory. It was covered with mountains and rivers, and the snow did not melt all the year round. The land was difficult to cultivate. Therefore, the people of the Northern Zhou Dynasty mostly made a living by herding and hunting. They had strong soldiers and horses. Although the military strength was the strongest among the countries, the tribes continued to fight among themselves, and they were generally in peace with the surrounding countries.
