Ye Han did know something about the Ten Thousand Demons Realm.
He was very unfamiliar with its interior, and the Ten Thousand Demons Realm was the largest of the many star realms. Otherwise, how could it support those enormous ancient beasts, or even divine beasts?
The reason entering the Ten Thousand Era Demon Realm had been so difficult for Ye Han was that divine beasts were part of the defenses of the Ten Thousand Demons Realm's Star Realm Barrier...
Truly powerful divine beasts possessed cultivation and divine abilities that were no weaker than those of true immortals!!
Some exceptional, powerful divine beasts were even stronger than true immortals. They, too, were immortal beings, and their cultivation and divine abilities were even more terrifying.
The most famous among them were the legendary Four Divine Beasts: the Azure Dragon, Black Tortoise, Vermilion Bird, and White Tiger.
In truth, these Four Divine Beasts were not remotely on the same level, nor did they stand as equals. Even their rumored appearances differed from their true forms.
The legend that these Four Divine Beasts were the ancestors of the demon beasts throughout the myriad realms was also nonsense. After all, how could offspring born to divine beasts become such lowly beings as demon beasts? Even a trace of divine beast bloodline was enough to turn many utterly ordinary demon beasts into immensely powerful beings.
So-called demigod beasts were not given that name simply because they possessed divine beast bloodlines. The term was much like half-step true immortal: their bloodlines approached those of divine beasts, but had not quite reached that level.
It was actually a matter of bloodline purity, not whether they possessed a divine beast bloodline at all.
These were all theories and research findings Ye Han had read in books written by cultivators.
