A giant Thunder Ray traversed on the ocean's surface. There was a topless woman lying on top of the Thunder Ray.
Her blue hair was blowing in the wind, while her long fishtail skimmed over the surface of the water and made splashes. As it made its way, the giant Thunder Ray released a predator-like aura of a highest tier magical beast. All of the monsters and magical beasts were terrified of this aura.
The Thunder Ray was the true son of the Sea God, and the one controlling it was a mermaid who also a descendant of sakun. It had been about a hundred years since the birth of the mermaid race. Since that time, they had grown into quite a big group.
At this moment, the mermaid that was riding the Thunder Ray suddenly noticed a giant shadow in the sky. She lifted her head and saw a flying castle that had just appeared from the clouds under the sun.
