On the desolate island.
Thunder, like a dragon, moved through the dense dark clouds, and the island below, as well as the sea, quaked, sending wave after wave of intense tremors, creating waves that seemed poised to drown the world.
"Boom!" Sol swung his thunder-carrying broadsword, clashing head-on with the approaching Ahtal, while his other hand, tightly gripping a sword, parried an attack from Miss Black Blade.
"Ahtal, don't hold back!" Sol's hearty laughter overpowered the thunder, his waist suddenly exerted power, transmitting it to his tightly gripped swords, forcefully flinging Ahtal and Miss Black Blade away.
He then took the opportunity to drive his swords into the ground. Purple thunder followed the blades down into the earth, spread, and submerged the entire island.
As the strongest human, he hadn't mastered an almost unsolvable ability but continually refined his magic power of the thunder attribute, developing as many applications for it as possible.
