Flashback - The 3 Beast Kings

Lumiel opened his eyes into the void. He saw bubbles of water into the depths of an ocean-like abyss. He was sinking slowly, breathing, and it made him wonder how he could breathe inside the depths of the sea. He moved his hands and he could feel the water currents slowly making him drift to the bottom.

It was a spectacular experience, but he jolted as he remembered what happened. "Did I die?" he questioned himself. Wondering if that was a dream or not. But as he recollected, he realized that it was all real. Soon after, he slowly rose from the waters and then burst out of the sea like a propelled bullet. Waters exploded and white light flashed.

Thirty minutes ago...

Inside the S-class rank dungeon, a vast wilderness was seen. The ground dirt was blown by the wind and from afar, a sea was seen.
