The moment Kent entered the sea, he started to hear wailing sounds.
It felt like the very flames burning around him were screaming. Of course, the feeling of water was also around him, but Kent felt the heat even more than the water.
This made him smile.
After all, he could tell his movement would not be hindered in any way.
However, there was a downside, and that was the heat.
He could tell from the heat that his flame resistance would have to step in. However, learning that he would be traveling perhaps 450,000km deep made him see the flaw in the advantage he had received.
If his flame resistance could not handle it anymore, then it meant he wouldn't be able to reach the depth of the Damned Hell Sea.
In that case, his chances of using perhaps a Supreme Primordial Flame - if the rumors were true - to form his Flame Core would be boycotted.
