Chaos Demons, like Great God Pangu, were all born within Chaos, that is, within this void filled with Chaos Qi.
In the Chaos Void, there were scattered chunks of land, and Great God Pangu lived upon one such land, which was also the precursor of the later Ancient Primeval.
As for the Chaos Demons, they resided on other lands.
Both were beings bred from Chaos, with no essential differences between them. Even in the eyes of beings like Ju Lo, among other Chaos Demons, Great God Pangu was also considered a member of the Chaos Demons, just one with exceptionally formidable strength.
"Great God Pangu is actually a Chaos Demon, that's really explosive news!"
Sun Wukong wryly shook his head, in the Ancient legends of the Three Realms, Great God Pangu was the supreme deity who created heaven and earth and nurtured all beings; he had not expected the truth to be like this!
"Being a Chaos Demon is no big deal!"
