Ancient God Domain was vast and borderless.
Wusha Wilderness was only a small portion of the Ancient God Domain and was easily ignored.
In normal circumstances, only when multiple Wilderness combined would a star territory formed.
When multiple Star Territories combined, it then became a Domain.
For example, Crimson Stone Saint was a Domain Lord in his mortal life who established the Crimson Stone Fort and was in complete control of a whole Domain. There were a total of 381 Star Territories within his domain.
A Domain Lord was a prominent figure in Ancient God Domain. Usually, only experts who were an Undying Saint or above were qualified to become the lord of a certain domain.
Although a Star Territorial Lord could not be compared with a Domain Lord, to be capable of leading so many Wilderness would require one to have possessed extremely high abilities.
