Three hundred years ago, the "Yanguang Empire" that unified the continent was divided due to civil strife and the invasion of northern aliens. The remaining forces were divided into three major human families. The northern aliens formed a unified "Black Abyss Tribe". The southern wasteland was scattered with alien tribes such as half-beasts, stone spirits, and feather tribes. The forces of all parties checked each other, and wars continued, which continued for hundreds of years.
