There were four territories in the underground world.
The Northern Territory, the southern territory, the eastern territory, and the western territory. Each of these territories amassed a population of above 30 billion individuals. Altogether, the population of the underground world was about 150 billion.
That could show how huge the underground world was.
The big three had their own respective territories. The northern belonged to the profane palace, the southern belonged to the heaven and hell organization, the eastern belonged to the house of omega and finally, the western territory which was regarded as the home for wanted criminals.
To all wanted criminals and forces, the western territory was like paradise to them. Cause decades ago, the big three placed a rule that killing is prohibited in that place.
No one knew why they placed that rule but they didn't dare go against it. Besides, it was a good thing having such a place.
