It was unknown what was under the Ocean Core since the natives had yet to reach that place.
Shallow Sea, Mid Sea, Deep Sea, Deep Ocean, and Ocean Core were the five different layers of North Blue and held organisms of different strength.
Ocean Core, which was somewhat known, extended up to two hundred thirteen thousand meters. The humanity had yet to reach the ocean bed, but it lacked the strength to dive any deeper.
The known depth of Earth's ocean was twenty seven thousand meters. In other words, the known depth of North Blue was already ten times greater.
But this wasn't what was the most terrifying since humanity had already reached three hundred and thirteen thousand meters in West Blue.
Given these facts, Li Yunmu found it extremely difficult to imagine the vastness of the Origin World. Just North Blue was so deep and immeasurable that even the natives were helpless.
