The Four Great Beast Clans are the oldest existing races on the Demon Beast Continent today.
After death, their souls enter the Ancestral Mountain of the Four Great Beast Clans.
This is known as the Ancestral Soul.
Of course, there are conditions for the Ancestral Souls to enter the Ancestral Mountain: the bloodline must be pure, and the cultivation must have at least reached the early stages of the Realm God realm.
Entering the Ancestral Mountain allows the mountain to preserve their souls indefinitely... However, leaving the mountain at will results in the loss of protection and the extinction of the soul...
The protectors of the Ancestral Mountain are known as the Tomb Guardians of the Ancestral Souls.
No one knows the identity of the Tomb Guardians of the Ancestral Souls.
All that is known is that as long as the Ancestral Mountains of the Four Great Beast Clans have existed, the Tomb Guardians have as well, protecting the mountains generation after generation.
