The dragon guards who were supposed to be holding their positions were now fighting amongst themselves, seemingly killing each other.

The four Dragon Kings had arrived, but many of their dragon guards still attacked them, which angered and alarmed the four Dragon Kings.

Among the dragon guards were many powerful elders who were stationed here. They all disregarded their injuries and attacked desperately, leaving the four dragon kings in a sorry state.

"Could it be that some of the guards have rebelled?" Princess Peacock wondered upon seeing this scene.

"Look closely at the expressions of those guards." Zuan originally wanted to set up a few concealment formations to hide the three of them, but seeing the chaos here, it was clear that the Four Dragon Kings had no time to worry about that anymore.

After his reminder, the Mermaid Queen and Princess Peacock observed carefully and discovered that the eyes of the frantic guards were somewhat grayish and lifeless.

Yet, despite their fierce fighting, they were lifeless, exhibiting two completely different states simultaneously, which looked extremely strange.

Moreover, they noticed that the guards rarely fought with weapons, but instead grabbed and bit with their bare hands. Any guards who were scratched or bitten by them would soon have a grayish-white aura appear on their bodies, becoming like them, and would then turn around and attack their companions.

"Is this some kind of Gu poison?" Seeing this, Princess Peacock couldn't help but swallow hard. But is there such a highly contagious Gu poison in the world?

"It's not poison, it's death energy." The Mermaid Queen's face was ashen as she pointed to the grayish-white gas that kept gushing out from below the canyon. "That's the death energy from the sea eye that the sea race has suppressed for generations, the most filthy and evil existence in the world!"
