Eighth Mountain and Sea

In terms of overall size, it was similar to the Ninth Mountain and Sea. It also had a sea, the major difference being that it wasn't called the Ninth Sea, but rather, the Eighth Sea....

There were also four planets which orbited the Eighth Mountain, although their names were different than the planets in the Ninth Mountain. And yet, when it came to the overall system of cultivation, and the way the place was set up, it was very similar.

After all, the Eighth Mountain and Sea and the Ninth Mountain and Sea were both parts of the Mountain and Sea Realm.

However, there was a barrier between each of the various Mountains and Seas, a barrier which was extremely difficult to pierce a hole through. That made it so that the cultivators from the different Mountains and Seas couldn't easily pass through. Unless... there was a war, and the power of countless cultivators could be converged to break through the barrier and enter the neighboring Mountains and Seas.
