Although no one in the entire universe didn't go beyond the Dark Region, there were many theories of other universes existing beyond it.
However, the Dark Region is very dangerous, and since it is filled with a mysterious evil energy that corrodes the cultivators' bodies, no one is willing to risk their lives searching for universes beyond the Dark Region.
Nevertheless, the top forces have gotten clues that there were other universes and other subsidiary forces for the Heavenly Sects and Organizations in those universes.
After learning that, they started finding ways to explore the Dark Region and even created the Corrosion Resisting Pills to temporarily stop the corrosion after entering it.
Although it's been more than a hundred years since these top forces of the Universe started exploring the Dark Region, they were progressing slower and still in the outskirts.
