Beyond the western inner sea region, in the dark outer sea region, a huge trench divided the black and blue seas like the gap between two overlapping tectonic plates.
However, this abyss-like dark opening wasn't just a simply large chasm; it was like an entrance to the underworld—Dark, gloomy, and deathly could describe its appearance. Sea life tended to avoid it, and no aquatic plants grew around it.
The ocean depths were generally cold, even freezing. But in this place, it was scalding hot, enough to cook all marine life below Rank 3.
The sea surface constantly bubbled and emitted endless steam like boiling water.
Due to the special conditions in this particular sea region, the sea weather in the area also became violent. Powerful storms and winds created a natural barrier, warding away all human ships and fleets.
Stubborn explorers who had ever challenged its power had all sunk into its abyssal depths, never seen or heard again.
