The expressions of the people nearby changed drastically. They knew that the Aurora Poison Dragon was notorious for its poison, and the blood inside its body was extremely toxic. Now that it knew it had no chance of survival, its desperate move to take everyone down with it was incredibly powerful. Just a little bit of its poisonous blood would probably cause soul-crushing and bone-destroying effects—literally.

Just then, Zaun stretched out his hand, and the light near the Aurora Poison Dragon's explosion suddenly distorted, as if there were a black hole there.

Then the filthy blood that had exploded retreated at a speed visible to the naked eye, eventually shrinking into a small ball that appeared in Zaun's hand.

The Mermaid Queen and Princess Peacock breathed a sigh of relief upon seeing this, praising Zu An's amazing skill. If it weren't for him, everyone present would probably be dead.

Zuan was secretly relieved. If he hadn't been proficient in both the mysteries of spatial transformation and the Gluttonous Devouring Heaven Technique, he probably wouldn't have been able to control the explosion of the Aurora Poison Dragon to a very small area in that instant.

His primordial energy circulated rapidly, quickly refining the extremely black ball of blood and filth until only a crystal-clear bead remained.

The Mermaid Queen exclaimed excitedly, "This is the inner core of the Aurora Poison Dragon! Your sister can be saved!"

She was initially worried when she heard that Zuan was looking for the Aurora Poison Dragon. After all, that guy was always elusive, few people had seen him, and it was extremely difficult for him to form an inner core. Even if they found him, he might not have an inner core.

Unexpectedly, the Aurora Poison Dragon delivered itself to our doorstep, along with such a pure inner core.

A smile appeared on Zuan's face. Finally, there was good news. He wondered if Xiaoxi and the others had found any other materials.

Princess Peacock's gaze darted back and forth between the two men, wondering if her eldest brother had a younger sister. She thought to herself, "Even the Queen knows he wants to save her. I guess I know too little. Should I ask the Queen, or should I spend more time with my eldest brother?"

At this moment, the Mermaid Queen suddenly said with concern, "Now that the Aurora Poison Dragon is dead, we may never be able to find the Four Seas Dragon Kings again."

Her beautiful brows were now filled with worry. The entire sea race had been poisoned and was on the verge of death. Now that even the Four Dragon Kings of the Seas were gone, the entire sea race was probably doomed.

Zuan put away the Aurora Poison Dragon's inner core and said calmly, "It's alright, I know where he hid the Four Seas Dragon Kings."

"How did you know?" The Mermaid Queen and Princess Peacock exclaimed in unison. They knew that given the Aurora Poison Dragon's resentment before his death, he would never have told the other party.

And it exploded instantly, so Zaun didn't even have a chance to interrogate the other party.

Zaun chuckled. That kid, Aurora Poison Dragon, was really dreaming. He thought he could just die and be done with it.

Little did he know that he was the ruler of the underworld.

Although the underworld's authority has been restricted in many ways, it can still hold his remnant soul captive.

His identity exerted a natural pressure on beings like ghosts. Aurora Poison Dragon never expected that even in death he would not find relief. The feeling of being faced with him after death was a hundred or a thousand times more terrifying than when he was alive. It was a fear from the depths of his soul that was beyond his control.

So they quickly told the Four Seas Dragon Kings of Zuan where they were hiding.

Zuan led the group to a cave a hundred miles outside the Dragon Palace. This cave was hidden in the coral reef. If someone hadn't led the way, they probably wouldn't have realized there was a cave even if they passed by it a hundred times.

"Be careful, there seem to be many insidious traps around here." The Mermaid Queen's expression was solemn. After all, she was knowledgeable and quickly saw through some of the formations and traps. However, there were still many formations whose purpose she could not understand, but they were certainly not for welcoming guests.

Zuan remained calm: "It's alright, just follow behind me."

As he spoke, he strode inside, as if the traps and mechanisms didn't exist.

The two women were taken aback, and hurriedly followed with the others, thinking that it would be good to help him protect the side.

Just then, countless traps and mechanisms were activated, and various magical lights bombarded the group, but they suddenly disappeared after flying halfway.

The Mermaid Queen and Princess Peacock exchanged a glance, both seeing the admiration in each other's eyes. They could see that Zu An's seemingly casual movements had actually placed him at the core of each array trap, neutralizing them before they could even be activated.

The two couldn't help but chuckle. Who was this person? Why would they need to worry about him?

The Xuan Su double guards following behind sighed inwardly. They were completely disheartened now. The gap between them was too great. They couldn't even see his back. No wonder the proud and arrogant princess fell in love with him at first sight.

Yes, only someone like her is worthy of being called a princess.

For a moment, they even felt a sense of absurdity: was the princess worthy of him?

Soon the group entered the cave. From the outside, the cave looked small, but inside it was very spacious. Four naturally formed stone pillars stood in the four directions, as if supporting the ceiling above their heads. The Four Dragon Kings were tied to these four pillars.

The Four Dragon Kings were no longer the majestic rulers they once were; their clothes were disheveled, their heads drooped, and their faces were deathly pale.

"Dragon King, Dragon King!" The sea creatures who followed could no longer bear it and hurriedly called out to their own Dragon Kings. Unfortunately, no matter how they called, the Dragon Kings of the Four Seas kept their eyes closed and their faces showed pain, as if they were experiencing some kind of nightmare.

The Mermaid Queen hurriedly warned, "Everyone be careful, there seems to be some kind of formation under our feet!"

Only then did the others notice some scarlet array patterns below the stone pillars binding the Four Dragon Kings. Looking at those scarlet array patterns, everyone felt a fierce aura rushing towards them, creating a natural sense of unease.
