From a macro perspective, the Daluo Immortal Realm is an incomparably vast world. Beneath this great world, there were originally thirty-six smaller lower realms, but a hundred thousand years ago, during the Yuan Gathering, a shocking battle ensued, causing the Daluo Immortal Realm to shatter, even breaking the barriers of the great world.
As for the thirty-six lower realms that relied on the great world for their existence, twenty of them were either shattered on the spot, occupied by the Wisdom Clan or fell into the Chaotic Demon Area. Only sixteen realms remained intact and still belonged to the Daluo Immortal Realm.
Each of these thirty-six lower realms originally had a special region known as the Nine Layer Void Prison.
From an existential perspective, the Void Prison is like the shadow of the world.
