Struggle
A moment later, his hand began to release a searing heat that burned through the Eel, only for Solaris' black flame to enter the insides of the Eel's body.
Using Solaris underwater was not exactly easy, but Jason also knew that if he had enough mana, he would have no trouble evaporating the entire sea.
Thus, the only thing he had to pay attention to right now was to regulate his mana consumption while diving further into the sea.
The marine beasts were not exactly strong, and their only advantage was the all too familiar environment they were in, and possibly their big size.
Marine beasts' size was far from the average beasts found on the ground, and they were known for being much larger than other beasts.
As such, Jason was not really intimidated when he sensed strong ripples within the mana, indicating a beast swimming past him.
