Wu Yu immediately turned to it. He saw that it was Celestial Demonic Emperor, in his true form as the Celestial Meteor. A huge comet was streaking through the mists, purple light trailing behind it. Clearly, he too had also discovered the presence of the Grave of Lifeless Eternal Demon Emperor.

He and Wu Yu's clone had spotted each other at the same time.

"You-!"

Celestial Meteor shouted. His first instinct was to attack, but he soon realized that this was not the only Wu Yu. There were many more identical Wu Yus all around him!

He then knew that these were but clones.

But even if they were clones, he did not intend to let them go. The shining violet starlight streaked past them, sending purple sword qi that cut Wu Yu's clones to bits.

Soon enough, he was standing before Wu Yu's recuperating true form. He knew that Wu Yu was injured.

"Hahaha, to think you're actually hurt here. Die!" Celestial Meteor was in a good mood indeed. He immediately unleashed his Starry Sword Hell heavenly rule that filled the air.

Wu Yu could not possibly take him on right now, and Starry Sword Hell heavenly rule was one of Celestial Meteor's stronger moves. Even in a whole state, Wu Yu might be hurt by this heavenly rule power, let alone after he was limping from the Maelstrom Silver Dagger Sphere, and his defenses heavily discounted.

Therefore, he used the Somersault Cloud to flee from the purple sword qi, vanishing from sight.

As Wu Yu left, the Starry Sword Hell heavenly rule automatically turned to the Maelstrom Silver Dagger Sphere epochal immortal design. Before Celestial Demonic Emperor could control it, the sword qi had rushed into the epochal immortal design, triggering a storm of silver daggers.

The silver daggers surrounded Celestial Meteor, and attacked him furiously. Celestial Meteor was immediately cut up badly as well.

Clearly, not even a 9-heavens demon king like Celestial Meteor could withstand the epochal immortal design's silver daggers or get near to the Grave of Lifeless Eternal Demon Emperor.

He immediately fled from the knives, and vanished into the thick mists again.

Wu Yu could not catch him even if he tried. He could only give up the chase, instead remaining to study the Grave of Lifeless Eternal Demon Emperor's epochal immortal design.

Wu Yu was currently wondering: Why would the Lifeless Eternal Demon Emperor use an epochal immortal design to protect himself?

Could it be that the Jade Emperor himself had set this epochal immortal design?

After all, the Jade Emperor had created this epochal immortal design for the 10th Grade Mark of an Immortal King as well, except that this one was way more savage.

If this epochal immortal design was really set by the Jade Emperor, then what was the relationship between the Jade Emperor and the Eternal Emperor Tomb?

Wu Yu could not guess the answer. Just like the Eternal Emperor Tomb itself, the situation was hazy, and he was just fumbling around in the dark.

He could only continue to study the grave. He had also made two more unsuccessful attempts to break past the epochal immortal design. The defense of the Maelstrom Silver Dagger Sphere was one that he could not overcome for now.

After a month, he made his third attempt to enter. But at this time, the entire Grave of Lifeless Eternal Demon Emperor and the Maelstrom Silver Dagger Sphere had altogether vanished!

Wu Yu was completely nonplussed.

How could the entire damn grave have gone missing?

Could it have all been a mirage? Or perhaps, were the graves in the Eternal Emperor Tomb constantly changing locations?

The mirage theory could not explain the epochal immortal design well. If the graves were constantly moving, then it would be much harder to crack them than he had imagined.

Wu Yu did not leave immediately, mapping out the possibilities for now.

But at this time, he was surprised that Celestial Meteor had returned. He had not only returned, but brought Dignified Lava Beast with him. The two 9-heavens demon kings had come together!

Celestial Demonic Emperor and Dignified Demonic Emperor had both completely recovered from their wounds previously. Wu Yu was definitely not their match.

Seeing that the Grave of Lifeless Eternal Demon Emperor had vanished, both immediately turned suspicious eyes on Wu Yu.

Celestial Meteor raged: "Damn it! We were too late. The grave is gone! The kid must have broken in and taken away the eternal demon emperor corpse!"

As for the Dignified Lava Beast, he naturally would believe Celestial Meteor's words. Since Wu Yu was still sticking around, then he had probably only just taken the eternal demon emperor corpse.

Therefore, the two demonic emperors surrounded him.

They knew that Wu Yu could flee well, and they might not be able to hold him. But for the eternal demon emperor grave, they could not let him go. They would do their best to kill him.

Starry Sword Hell heavenly rule came at him again. Jets of purple sword qi came whistling towards Wu Yu from the mists!

As for Dignified Lava Beast, he howled and called upon Casting Heavenly Rule. A pillar of fire descended from the skies on Wu Yu.

Against their powerful attacks, Wu Yu could not take it head on. His only option was to flee. But he did not use the Somersault Cloud to flee yet. Instead, he used Lawful Embodiment of Heaven and Earth to shrink himself down, and then dodged them with his enhanced speed.

Just as Wu Yu was about to leave, Dignified Lava Beast suddenly shouted: "Punk, you dare to leave? If you leave, your mystical dragon companion will die. Olden Demonic Emperor, Perpetual Demonic Emperor, and Unending Demonic Emperor have already captured him, and we're waiting for you to join him!"

Wu Yu frowned upon hearing this. He did not know if it were true.

Celestial Demonic Emperor sniggered. "Go on then. Leave. See how badly your mystical dragon friend gets tortured. Can you bear to see him die because of you?"

The two applied considerable pressure on Wu Yu.

If what they said was true, then Wu Jun was in trouble indeed, and required his help. If not, Wu Jun might well be tortured to death.

In any case, he had not seen Wu Jun for a long time now, and their words were plausible.

Wu Yu could not take the risk. He had to give them the benefit of the doubt. In any case, they could not do anything to him as long as he kept his distance. One flip with the Somersault Cloud and he would be out.

"If what they said is real, then the scene of Wu Jun dying must have been fake!"

This was good news for Wu Yu indeed. He still clearly felt trauma from that memory.

If Wu Jun was not dead, then all was well.

Therefore, Wu Yu replied tersely: "Lead the way then. You want the bronze pendants right?"

"Of course. But some time has passed, and we can't be sure that we can find them." Dignified Lava Beast said.

"We can only give you a rough direction."

Celestial Meteor said, pointing.

In that case, Wu Yu had no further need of the two. He left in a flash. His clones could scout much better than their bumbling guidance.

To think he had believed for a moment that they could show him the way.

However, Wu Yu knew that he had to be quick. Each moment he delayed could endanger Wu Jun's life.

He immediately turned his 1 million doppelgangers loose, scattering in all directions. He himself left on the Somersault Cloud in the direction that the Celestial Meteor had indicated.

Both of the demonic emperors were taken aback at Wu Yu's audacity.

After a beat, Celestial Meteor laughed. "No matter. Even without us two, they can't do anything against those three either. By the time we arrive, the key will certainly be in our hands."

Dignified Lava Beast dipped his ponderous head in agreement, and followed Celestial Meteor into the mists.

A few days later.

Wu Yu had searched as hard as he could for the location of the other three demon kings, and one of his clones finally hit upon it three days later.

Wu Jun was indeed captured by the other three. The coarse branches of the Perpetual World Tree had completely bound Wu Jun. Half of his Primordial Immortal Dragon body was also sheathed in a golden metal, the other half frozen solid by the Unending Crepuscular Sea. He looked to be in completely agony.

Wu Yu's clone immediately drew the attention of all three demonic emperors.

All three turned to him, and demanded: "We can finally negotiate properly! Hand over your bronze pendant, or the mystical dragon dies!"

The three demonic emperors had teamed up to trap Wu Jun. The situation looked hopeless, but Wu Yu could not allow Wu Jun to be hurt!

Therefore, this was a negotiation that he had to see through. He could well give up the pendant, but Wu Jun could not die.

Therefore, Wu Yu began negotiations immediately, calming them down. His real body sped over to the location.
