The elder in black robes, being a member of the Human King Hall, naturally knew about the existence of the five-class realms.
He even knew that the Yellow Cloud World they inhabited was seen as an Abandoned Land in the eyes of those pure-blood humans.
In the All Heavens and Myriad Realms, the Human Race was divided into two main categories.
One category was the humans with extremely pure bloodlines, who called themselves Pure-blood Humans.
The other category was the humans with bloodlines of other races within them.
This type of human was also mockingly referred to by Pure-blood Humans as Mixed-blood Humans.
Mixed-blood Humans, among all humans, were not actually very numerous.
However, because they carried the bloodlines of other races, they were generally discriminated against by Pure-blood Humans.
And the Yellow Cloud World, from some unknown point in time, became a gathering place for Mixed-blood Humans.
