Return of Supreme
Emperor
Chapter 162: 1 on 1
Heavenly realm-
A place where god lives or that's how it should be
When the god created the world, he didn't stay in the world of mortals but he made a heavenly realm where he could live in ease and look down on mortals
But over the passing time, he got bored and left off into creating some other world
But before he leaves the place he created few people who could keep an eye over the mortals and these people are called gods today
Humans think that they are immortal because they can do almost anything but in truth, they are just like mortals on the ground who greed and lust overpower
As for the demons, they are people who fall from the position of True Gods servant as they betrayed him
So, these fallen gods are called demon who lives in the underworld realm
