Overseas
The forbidden Sea.
The forbidden Sea had always been extremely mysterious. In ancient times, it was called the bitter sea. The bitter sea was boundless, and its circumference was unknown.
The forbidden Sea had been an extremely mysterious place since the heaven realm was still around.
After the heaven realm crashed, the forbidden Sea became even more dangerous. There were countless spatial cracks on the sea's surface, and the seawater's corrosive ability was extremely strong.
If an ordinary rank-9 entered the forbidden Sea, they would be in danger of dying if they went a thousand miles deep.
Even peak cultivators would face the danger of dying if they didn't have a place to stay in the forbidden Sea for long.
There were 33 great immortal islands scattered across the ocean, and they were also the currently known overseas forces.
