A hundred years ago, the demon world wreaked havoc on the human world. The four divine beasts, Green Dragon, White Tiger, Suzaku, and Xuanwu, protected the peace of the human world and used their own divine power to seal the demon king in Buyou Mountain. The demon world was severely damaged after this war. The fossils of the last four mythical beasts are scattered in the four directions of the capital to protect the human world and maintain the peaceful life of the human world for hundreds of years.
However, the demon world is still ready to stir up troubles after hundreds of years. The demon world is now divided into pieces. There are many strong men from various tribes vying for the position of the new demon king, and internal strife continues. Until recently, there was a sudden change in Buyou Mountain. The moon hanging on Buyou Mountain turned blood red, and rat infestations broke out in several villages of the human race. All these signs indicate that powerful monsters may appear in the future. Such signs have attracted the attention of the entire demon world and the human race.
