Shanhai Pass.
The Ten Celestial Passes, the Territorial Battlefields.
The collision between the Mountain and Sea and Primordial Space-Time formed fractal, tree-diagram-like space-time nodes.
At the root of the tree diagram lay the Ten Celestial Passes.
In the Chaos Abyss, the Primordial Chaos of the two realms clashed.
Further down, bound by the barrier of the Primordial Path, the Mountain and Sea could not act without restraint.
Nine Heavens Pass: the clash of Great Emperors, the All Heavens Great Emperors.
Eight Celestial Passes: Quasi-Emperors and Great Emperors.
Seven Days Pass: Great Venerables and Quasi-Emperors.
And so on down the line.
On the battlefields of the Five Celestial Passes in Nether Heaven, the high-level combatants on both sides were typically in the Venerable Realm.
There were, however, a few weak points where the repulsion of the Great Dao was weaker.
For example, the Reincarnation Battlefield.
Or the Dead Sea Main City.
