As Wu Yu had just broken through to the Great Void Immortal Realm second tier, he was stronger than ever before.

Primitive Demon King could originally beat him as long as Wu Yu did not go to the extremes with Immolate. But after devouring the eternal demon emperor corpse, Wu Yu's improvement within these 5000 years had been ridiculous.

Wu Yu appeared coolly before Primitive Demon King, changing into his golden ape form. Lawful Embodiment of Heaven and Earth caused Wu Yu to grow many times larger than Primitive Demon King.

"Incandescent heavenly rule!"

Wu Yu finally used his first heavenly rule power!

Golden flames came together to form a tidal wave that all but swallowed Primitive Demon King. With the buffs from Lawful Embodiment of Heaven and Earth and Violent Art, Wu Yu's incandescent heavenly rule was capable of terrific power.

Primitive Demon King had been in his true form, the Primitive Gold Devouring Rat. That was already his strongest state.

He had not noticed that Wu Yu's real body was attacking him. He had not expected Wu Yu's real body to dare to face him head on.

And now incandescent heavenly rule surged towards him inexorably, sweeping him up and leaving nothing behind but a frightened squeak. Primitive Demon King wanted to defend himself, but found himself laid bare before Wu Yu's incandescent heavenly rule.

Wu Yu's second tier of Eternal and Indomitable Vajra Realm gave him incredible strength. Primitive Demon King only managed one squeak before Wu Yu's incandescent heavenly rule finished him off.

One heavenly rule, and a 6-heavens demon king lay dead. That was his strength.

Wu Yu quickly changed into the Heaven Devouring Titanic Beast and devoured Primitive Demon King. In terms of dao contemplation, Primitive Demon King could not hold a candle to the eternal demon emperor corpse.

But he was in urgent need of strength, and also to silence those in the know. Although the devouring was not that useful, but even a mosquito's leg was still sustenance.

Wu Yu was in a hurry to return to the sky palaces. He could not wait.

Luo Pin was there, and he was anxious to know how she was.

He wanted to go and get the truth out of Nangong Wei. As to what had happened on that day.

By devouring Primitive Demon King, Wu Yu could also get his memories from before. There might be some important information regarding the Demon Immortal Realm.

Of course, he did not pay too much attention to these memories. There was nothing outstanding that he wanted to know from Primitive Demon King.

But he got a pleasant and unexpected gift of knowledge!

Concerning Jiu Ying!

There had been no news of Jiu Ying since he had ascended to Demon Immortal Realm. Wu Yu had been very concerned about him.

He had searched for a long time, but there had been no response. And now there was news.

He had his doubts about this information.

Of course, Jiu Ying was still alive. And he was in an unbelievable place.

However, this was not the time for processing information. In the moment that he had finished off Primitive Demon King, Primitive Demon King's final squeak had echoed throughout the black sea, and the other demon kings would soon arrive.

Wu Yu pushed the news of Jiu Ying to the back of his mind.

Wu Yu immediately prepared for the fight.

The entire black sea was restless now. Primordial Forbidden Demon King, Dreary Gold Demon King, and Golden Rhino Demon King all hurried over towards Wu Yu's position. They came from three different directions, surrounding Wu Yu.

As for the 5-heavens demon kings, they too had formed a similar surround, however, they had to contend with Full Moon of Nanshan and Ye Xixi.

Combined, the two could deal with a 6-heavens demon king. Three 5-heavens demon kings should not break too much of a sweat.

After stopping the 5-heavens demon kings, Full Moon of Nanshan and Ye Xixi teamed up and used all of their knowledge and heavenly rule power to fight them.

The three 5-heavens demon kings, including Eight-winged Purple Gold Mosquito, Eight-eyed Fire Elemental Ape, and Archaean Golden Tree, were in their true forms. They did not take Full Moon of Nanshan and Ye Xixi seriously at first.

But as the pair teamed up and unleashed their heavenly rule power, the three demon kings were aghast.

There was not even time for their jaw to drop.

Seizing the initiative, the two pressed their advantage, threatening their life from the get-go!

The three demon kings found it hard to even bring half of their power to bear. They were completely and totally shut down. This was the consequence of them underestimating their opponents.

However, this side battle did not affect the three 6-heavens demon kings too much.

To them, more dead demon kings meant less to fight over the eternal demon emperor corpse. Plus, they had Wu Yu surrounded. He was in their hands now, and could not possibly escape.

"How much of the eternal demon emperor corpse is left? Speak the truth!"

In his true form of jellyfish and octopus, Primordial Forbidden Demon King floated in the black sea as comfortably as a fish in water. This environment was his turf, and best suited for him to unleash his best powers. Therefore, he was extremely confident of emerging as the ultimate victor.

Although this matter had dragged on for too long - a full 5000 years had passed - but all was worth it as long as they could get the eternal demon emperor corpse. All depended on this final fight.

Dreary Gold Demon King had also reverted into his Dreary Elemental Vajra Lion form. His lion eyes were fixed on Wu Yu. "You killed my little brother. You must pay for his life. Today your judgment has come!"

Golden Rhino Demon King was also in his Golden Horned Ancient Colossal Rhino true form, and he trumpeted: "Was Golden Horned Demon King killed by you as well? If not, you only need to hand the eternal demon emperor corpse to me, and I will leave. I will not care whether you live or die."

It seemed like Golden Rhino Demon King was not too concerned about Golden Horned Demon King now. After all, some time had passed, and the eternal demon emperor corpse was the more important matter. If he could obtain the corpse, it would make for quite a treasure too.

The way Golden Rhino Demon King saw it, Wu Yu must want life more than the eternal demon emperor corpse. As long as he handed over the corpse, he could live. How could one not gladly accept the deal?

With the eternal demon emperor corpse in Golden Rhino Demon King's hands, he would hold the advantage. At that time, he would not care what happened to Wu Yu, or if Dreary Gold Demon King ended up killing Wu Yu.

As for Primordial Forbidden Demon King, he only cared about the eternal demon emperor corpse. No matter what, they all had Wu Yu surrounded, and he was dead to rights.

But Wu Yu did not waste words with them.

These three demon kings did not know that in the last 5000 years, Wu Yu had already completely devoured the eternal demon emperor corpse and reached a terrifying new level.

These 6-heavens demon kings individually were not Wu Yu's match. Even with the three of them combined, they could only fend him off for a moment.

Plus, the three still held some distrust amongst them. Dealing with them would be even easier now.

To Wu Yu, Dreary Gold Demon King had to be dealt with first. Because he had been on good terms with Elemental Gold Demon King, he could not possibly forgive Wu Yu for killing his brother before his eyes.

Therefore, Dreary Gold Demon King held the most killing intent against him. The other two were not that bent on killing him. They just wanted the eternal demon emperor corpse.

"If that's the case, let's fight then."

Wu Yu's blood boiled with passion and lust for war. He craved this sort of hard fight. With the Great Sage, Heaven's Equal's legacy within him, each fight honed him and helped him to grow.

The Victorious Fighting Buddha's legacy had to be honed through countless battles in order to triumph.

As the three 6-heavens demon kings hurled verbal assault at Wu Yu, they did not expect that Wu Yu would ask for some action instead.

"Crusader heavenly rule!"

Surrounded, Wu Yu finally used the crusader heavenly rule seared into his kingly immortal spirit!

A terrifying aura and strength coursed through Wu Yu's body. With the support of crusader heavenly rule, his entire strength was elevated further, and even his physical flesh was fortified.

And then, amidst the shock of the three 6-heavens demon kings, Wu Yu again used the Somersault Cloud Mystique,which they did not understand. Void Reversal took hold, and Qian Kun world and void world flipped. The three 6-heavens demon kings were in his realm now, completely separated from the environment outside.

"Let's get down to business then, enough with the talk?"

Feeling that he had been enfeebled in the void world, Primordial Forbidden Demon King's indignation and fury spurred him on. He had never been a particularly talkative one, and was ready to attack Wu Yu.

His goal was the eternal demon emperor corpse. Wu Yu's life meant nothing to him. He would kill Wu Yu first, and then search for the eternal demon emperor corpse.

"Primordial forbidden heavenly rule! Primordial sealing technique!"

The Primordial Forbidden Demon immediately drew upon his own heavenly rule power. A deadly beam of golden light flew out of his jellyfish-octopus body, headed straight for Wu Yu.

This primordial forbidden heavenly rule was Primordial Forbidden Demon's killing blow. Even if 5 or even 6-heavens demon kings tanked this blow, they would be severely crippled, and their bodies might even decay, or be completely incapacitated.

"Dreary Gold Imperial Pyre!" Dreary Gold Imperial Pyre also used his heavenly rule power. A purple-gold fire streamed forth from his mouth. This was the same terrifying heavenly rule power that he had used in the black sea previously. Now, it was completely concentrated, heightening its potency. It was concentrated wholly on Wu Yu, and he could feel the incredible pressure that it exuded.

"Golden horn heavenly rule!" Golden Rhino Demon King shot out golden light from his horn, and then a golden field began to expand around his body. It even seemed to layer over Wu Yu's entire void world, causing Wu Yu to fall within it.

The three 6-heavens demon kings attacked at the same time. To Wu Yu, this was the toughest challenge he had ever faced. But this was also the toughest Wu Yu to ever show face!
