Sensing that the aura on the opponent's body suddenly increased several times, Feiyu frowned deeply. He couldn't understand why the opponent's strength could improve so quickly after transforming his Martial Soul, and his speed also became faster.
The opponent's terrifying speed unexpectedly made him lose his advantage in speed!
At this moment, Duan Gujin had already merged with his Giant Demon Dragon Martial Soul, which made him much faster than the Sea Shark.
However, since Feiyu's strength was a realm higher than Duan Gujin's, their swimming speeds in the ocean were almost the same.
Sensing that his swimming speed in the ocean was on par with the opponent's, Duan Gujin breathed a sigh of relief.
Although the black Sea Shark was faster in speed, when it tried to approach Duan Gujin, the Domain Power that Duan Gujin released would slow it down.
In this way, Duan Gujin could use the Golden Body Treasure Sword to slay that black Sea Shark.
