Rui was not pleased by Jormungandr's disapproval of him; however, he would be lying if he said there was no merit to the serpent's words.
The fact of the matter was that he simply didn't have any underwater capability.
And for good reason, of course.
Very few battles happened underwater.

He heaved a sigh, putting a pin on the matter before departing from the region.
He had achieved what he had come for, and that was good enough for now. With the current system they had, trade vessels would be able to move back and forth between the true world and the Panama Continent, while warships would be capsized by the monsters of the Great Nam Ocean.
"With that, I have largely taken care of all my responsibilities."
