Rogel asked some more questions.
It was as if he gained a bit more understanding of the Dark Bottom Fish Cave.
He had a vague feeling, as though this was a person... or a god?
In any case, it's as if it was purposely built to facilitate passage between various sea regions.
The Abyssal Whale revealed that it had once helped some "supreme beings" travel to other sea areas, just like today.
This made Rogel realize.
Probably some other demigod beings.
It seems that even powerful demigods still try to avoid entering the boundary fog as much as possible.
This is indeed a reasonable explanation.
Besides that, Rogel obtained a piece of information.
Speaking of which, it started from his first ride on the Abyssal Whale.
At that time, the Abyssal Whale suffered an unknown accident and was suddenly gravely injured, but they still reached their destination safely back then.
