The level of difficulty of finding divine essence was not the slightest bit less than finding a divine artifact.
Following the disappearance of Divine Dao, divine essence this sort of thing already became lesser and lesser in the Divine Realm.
One could say it decreased with each use.
Only inside the grotto left behind by Deity Realm powerhouses could one find divine essence this sort of thing.
These divine essences were all energy that Deity Realm powerhouses used to maintain the operation of the grotto. Along with the passing of time, divine essence would get lesser and lesser too.
Furthermore, the grotto of Deity Realm powerhouses, the degree of danger went without saying.
Even if divine king powerhouses entered, it was also nine chances to die, and one chance to live!
The strength of Deity Realm powerhouses was completely not what Dao Profound Realm could try to fathom.
