"An alien race, originating from the human race, they are ferocious and aggressive in nature. They were transformed after being tortured by the fire of the Abyss of Ten Thousand Souls." After being bound by the thick cocoon of oppression, struggle and ambush in the Central Plains for thousands of years, they were reborn in Nirvana and seized the position of overlord of the Central Plains. Bearing unwillingness and humiliation, the people of the Central Plains were divided into various tribes, and the alien tribes were embattled on all sides and became the target of public criticism.
