Two Realms Mountain.
With his current knowledge, Han Yi had come to understand the true nature of Two Realms Mountain.
It was a fully open and mobile Cave Heaven world.
Unlike Dark Moon Sky Nexus, which is semi-open, one could only see a phantom of such semi-open Cave Heavens from the Void, unable to perceive the wonders within, yet from inside the Cave Heaven, one could clearly see everything outside.
However, Two Realms Mountain was a fully open Cave Heaven, existing as if it were a mobile castle without any restrictions.
In ancient times, before the Immortal Realm was shattered and before the Chaos Demons came into being, this Cave Heaven served as one of the tools by which the Daluo Fairy Court communicated with its subordinate domains.
