After 5000 years, Wu Yu first sent his clones out to assess the situation. He actually found a few familiar figures patrolling the black sea, searching the void chasms one by one.

"The black sea is so vast and there are uncountable void chasms. They're actually searching them one by one. Admirable. A pity for them they didn't find me."

Wu Yu was glad. If he had been found, his cultivation would have been interrupted.

It was hard to say how things would have turned out then. After all, Wu Yu had not been so strong back then, and unable to deal with a pack of 6-heavens demon kings.

But now, Wu Yu's luck had held. His clones had found traces of them, and he knew that they were left with the last tenth of the void chasms before their search was completed.

Full Moon of Nanshan and Ye Xixi were still cultivating, and Wu Yu had to buy them time. After all, they were in a crucial period, using the 9th Grade Marks of an Immortal King and attempting to break into the Great Void Immortal Realm.

This was of paramount importance to them, and Wu Yu could not let them be interrupted. Therefore, after mulling it over, he decided to wait for a while. He would send even more clones out once they were close to his location, to befuddle the demon kings. That way, he should be able to buy time until the pair were done cultivating.

Currently, both Full Moon of Nanshan and Ye Xixi were at the ninth tier of the Immortal Lord Realm. They were 9-realm immortal lords.

This was no small feat, but the most important thing was to reach the Great Void Immortal Realm. That would be a thorough evolution for them.

In the next 100 years, they had searched most of the void chasms now, and only a few thousand were left unsearched.

Wu Yu gaged that they were near as well. Before they stumbled upon his exact void chasm, he had already sent out 100,000 unshackled doppelgangers.

The black sea, silent for 5000 years, was again stirring to life. After so long without news of Wu Yu, the demon kings were on the verge of giving up.

But suddenly Wu Yu appeared in the black sea. This immediately galvanized the demon kings to action.

"There he is! The kid is a really slippery fellow! We must catch him! See how much of the eternal demon emperor corpse remains!"

Primitive Demon King leaped up in joy. He immediately charged into the black sea. He had waited for this moment for too long.

He guessed that Wu Yu must have consumed the eternal demon emperor corpse during this time.

But he was only at the Immortal Lord Realm. If he truly consumed the eternal demon emperor corpse, he would definitely explode from the overload of power.

But if he succeeded, Wu Yu might use the eternal demon emperor corpse to reach the Great Void Immortal Realm.

And even so, he would only reach the Great Void Immortal Realm first tier. In 5000 years, he could not possibly finish digesting the eternal demon emperor corpse.

How could they know that Wu Yu had the Heaven Devouring Avatar and the devouring ability, and was able to devour far more than they could imagine?

No matter what, the demon kings from before were no longer Wu Yu's match.

Of course, this depended on Full Moon of Nanshan and Ye Xixi successfully wrapping up their cultivation this time, breaking through to the Great Void Immortal Realm. That too was a crucial step.

The 100,000 unshackled doppelgangers were released by Wu Yu, fleeing to the furthest corners of the black sea. Besides, each unshackled doppelganger was also more powerful now, bolstered by the eternal demon emperor corpse's powers. Although they had yet to reach their peak, but they were a force to be reckoned with.

Any one clone could fight with a Great Void Demon Immortal Realm demon king. Therefore, when 100,000 clones appeared, Primitive Demon King could only deal with them one by one. And Wu Yu was an expert at playing hide and seek.

When these demon kings realized that there were 100,000 Wu Yu clones in the black sea, their heads felt ready to explode.

All of these clones were like the real Wu Yu. There was no way to differentiate real from fake. Deal with one, and there were more. Infinitely more.

More importantly, those clones that they finished off returned to Wu Yu's body as golden monkey hairs. Wu Yu could continue to create more clones, and send them out to cause more trouble.

Wu Yu had close to perfect vision within the black sea now.

Besides, with a constant stream of unshackled doppelgangers everywhere, it was nigh impossible to detect which void chasm they had come out from. They could find no purchase on Wu Yu's location.

Wu Yu's clones had attracted the attention of all the demon kings.

These demon kings were thinking furiously. Wu Yu might well try to make his escape amidst all these clones. At the same time, this technique wore down the demon kings significantly. The 100,000 dopplegangers was like nothing they had seen before.

If they had such a doppelganger technique, they would not have spent so much time searching for Wu Yu. At most, they would have taken 100 years.

But the world did not function on ifs. This was the Great Sage, Heaven's Equal's ultimate Mystique. Who could possibly have it?

Wu Yu continued to buy time with the Unshackled Doppelganger skill, causing the demon kings to tear their hair out in frustration.

And Wu Yu himself clearly knew that the demon kings guarding the black sea were basically the same few as before.

Primitive Gold Devouring Rat, the Primitive Demon King.

Primordial Forbidden Demon, the Primordial Forbidden Demon King.

Dreary Elemental Vajra Lion, the Dreary Gold Demon King.

And Golden Horned Ancient Colossal Rhino, the Golden Rhino Demon King.

In these 5000 years, Golden Rhino Demon King had already given up on Golden Horned Demon King, who had not turned up at all. he had even sent people out to search, to no avail. He was more or less sure that Golden Horned Demon King had been killed by Wu Yu.

He had not known before that Golden Horned Demon King had already been finished off.

The power of devouring and the Great Sage, Heaven's Equal's techniques were way beyond the ken of these demon kings.

These four 6-heavens demon kings, if united, could still pose a threat to Wu Yu.

Of course, Wu Yu was no longer afraid of them. They were mere annoyances to him. These demon kings had not spread the word, unwilling to let news of the eternal demon emperor corpse leak.

By happy coincidence, Wu Yu did not want the news spread either. It would cause him trouble. Therefore, this was good news.

Of course, at the same time Wu Yu had to finish them off. Otherwise, they would definitely spread the word to the entire Demon Immortal Realm when Wu Yu left. At that time, trouble would be around every corner.

To Wu Yu, the most important thing that he had finally reached the Great Void Immortal Realm after a long, long journey of cultivation. Even his Invincible Vajra Body was at the final realm now. He naturally wanted to test out the limits of his power!

How did he compare to these elite demon kings? To Baiqin Dragon Queen and Baiyin Dragon King?

That was his inner pride speaking.

Therefore, after spending so much time keeping his head down, how could he not flex his muscles in battle?

Crusader heavenly rule - it was his rule. Of course he would fight without fear.

Time continued to tick by. Wu Yu used his 100,000 Unshackled Doppelgangers to run rings around the demon kings, continuing to buy ample time for Full Moon of Nanshan and Ye Xixi.

Finally, after more than 200 years after Wu Yu had reached the second tier of the Great Void Immortal Realm, Full Moon of Nanshan and Ye Xixi attained their respective breakthroughs, fusing with their 9th Grade Mark of an Immortal King to successfully reach the first tier of the Great Void Immortal Realm!

Both of them were one tier below Wu Yu, but in terms of fighting strength, they were far behind.

Wu Yu now had the Eternal and Indomitable Vajra Realm's quasi-invulnerability. He could definitely take on a 7-heavens demon king!

As for Full Moon of Nanshan and Ye Xixi, they could both deal with fifth tier Great Void Demon Immortal Realm cultivators. If the opponent was at the sixth tier, they would have to join forces.

After all, Wu Yu was the amalgamation of the Heaven Devouring Avatar and the Great Sage, Heaven's Equal's legacy. In terms of fighting, he had other advantages.

As both of them made their breakthrough, it was about time for the counterattack.

"After we go out, you two deal with the five 5-heavens demon king. There are three main ones: Eight-winged Purple Gold Mosquito, Archaean Golden Tree, and Eight-eyed Fire Elemental Ape. The three of them are Purple Gold Demon King, Golden Tree Demon King, and Eight-eyed Demon King respectively. They're all yours."

Wu Yu assigned them accordingly.

Of course, Ye Xixi and Full Moon of Nanshan would not shirk their responsibilities. Having just made their breakthroughs, of course they had to test it out and familiarize themselves with their newfound power. Therefore, they had no problems with Wu Yu's assignations.

Ye Xixi was a little worried: "Big brother, that means you're dealing with the remaining 6-heavens demon kings? Isn't that too dangerous? There are four of them, after all."

"Shouldn't be a problem. I'll use the clones to confuse them and isolate one. Three should be no worry."

Wu Yu would not be too reckless either. There was no need to fight a 1 v 4. His goal was for them to die, and take the secret of the eternal demon emperor corpse to their graves.

After they had fleshed out the plan, the trio left the void chasm.

There were many Wu Yu clones milling around the black sea. Many of the demon kings were frazzled. Some of them had even joined forces in order to clear through Wu Yu's unshackled doppelgangers faster.

When they teamed up, they could indeed clear through the clones with speed. There were actually not many clones left.

In such a situation, Wu Yu left the bunch of demon kings undisturbed, and singled out a lone 6-heavens demon king: Primitive Demon King.

The Primitive Gold Devouring Rat was quite a selfish and scheming one. Therefore, he had not moved with the other demon kings. He might be thinking that he could kill Wu Yu's real body alone, and then take the eternal demon emperor corpse all for himself.

This gave Wu Yu a chance. If he could kill off Primitive Gold Devouring Rat, then the three 6-heavens demon kings united would not be as big a problem.

Primitive Gold Devouring Rat was currently scything through Wu Yu's clones with an irritated expression.

Capitalizing, Wu Yu immediately appeared before him. Before his identity was revealed, he unleashed a savage blow!
