The Underworld is not like the Yang Realm; it has powerful ghosts as well as weak ones, with a clear hierarchy. For instance, an ordinary Ghost Officiant can't compare to the might of Black and White Impermanence, and similarly, Black and White Impermanence can't match Yanjun's level. The same is true for ghost cultivators.
Chu Hao asked, "What's the origin of this Foreign Ghost Army you speak of?"
The ghost cultivator replied, "Foreign Ghosts are monsters that exist on the edge of life and death, the Netherworld's cancer. Our task as ghost cultivators is to eliminate them."
Wang Junshu couldn't help but ask, "What's the difference between the Netherworld and the Underworld?"
The ghost cultivator explained, "The Underworld might seem vast to those in the Yang Realm, but it's merely a part of the Netherworld."
