In the underground world, there is a place that even the most ambitious powers would not want to touch - the filthy land. There are scorched lands, endless mountains and unfathomable abyss everywhere. There are no lakes, no rivers and no vegetation, hiding countless deadly dangers. However, intelligent creatures were also born in such a place, which was named "Filth" because of the place of birth.
Since there is no other food, the filths can only survive by eating each other. A small number of filths survived the constant fighting and left their homeland to travel to the Six Realms. Almost all the filth that comes out of here will bring disaster, so the filthy place is also called the "place of disaster", which means the source of disaster.
