The Demons' World is one of the Six Major Worlds in the storyline of the Chaotic Sword God. Like the Daemons' World, It is headed by the Immortals' World.
As for the current situation in the Demons’ World, it’s half-destroyed. The ways of the world are damaged, and the laws are in decline.[1]
It has become more and more difficult for people in the Demons’ World to cultivate, so their overall power is nowhere close to the Saints’ World or the Immortals’ World.
The Demons’ World will probably face the same fate as the Spirits’ World in the near future. It is also one of the reasons why some of the races there have already migrated to the Immortals' World.
