There was only one chance for Wu Yu.

If he could not defeat Black Yama Demon King, then all he could do was to escape with the Somersault Cloud. In that case, the eternal demon emperor corpse would definitely be lost to him.

And it was Black Yama Demon King who would get the eternal demon emperor corpse. His improvement from it would be unimaginable.

Wu Yu had no wish to see the following repercussions either. He would be troubled if another bounty was set on his head.

Therefore, Black Yama Demon King was a must-kill for Wu Yu. And the eternal demon emperor corpse a must-get!

And being so close to the eternal demon emperor corpse was of great help to his fighting power.

Perhaps his usual fighting would be unable to defeat Black Yama Demon King. But with this eternal demon emperor corpse here, Wu Yu had a chance.

"Immolate, Immolate!"

Wu Yu immediately changed into the Heaven Devouring Titanic Beast. THe grotesque beast appeared before Black Yama Demon King, and immediately used its Immolate ability!

Against the Black Yama Demon King, only Immolate would do!

And not just ordinary Immolate, but Immolate Ultimus!

This level of Immolate would probably require 10,000 years to recuperate after battle.

However, there was an eternal demon emperor corpse here. If he could just get it, he would not need to spend so much time.

Of course, the precondition was that Wu Yu needed to be able to beat Black Yama Demon King!

He had to go wild. This was a gamble. If he could not get the eternal demon emperor corpse, and also Immolated so much, then all of his previous work would be negated, and he would have to start from square one.

Immolate Ultimus caused Wu Yu's immortal spirit and Mystiques to all heat up.

After transforming into the Heaven Devouring Beast and catching fire, an oppressive aura filled the field. He gave a reverberating roar, and even Black Yama Demon King was intimidated by his appearance.

The black flames encased his body, until even the black seawater evaporated around him!

"You're clearly just an Immortal Lord Realm kid...... No matter what methods you use, you're dead for trying to ruin the mighty Black Yama Demon King's business!"

Black Yama Demon King's Black Sea Yama Beast true form was also preparing to attack. The heavenly rule power within him burst forth just as Wu Yu was immolating.

"Black sea heavenly rule!"

From the many suckers on his Black Sea Yama Beast body, countless water pillars shot forth.

These jets of water were already deadly individually. They possessed terrifying destructive power, and could torpedo their way through the entire black sea.

If Wu Yu was hit by these water jets, his life would be in danger. Therefore, he instantly reacted.

"Void Reversal!"

His Mystique took hold, and Void Reversal flipped the Qian Kun world and the void world abruptly!

The water jets that had been hurtling towards him fizzled out, blocked by the reversal of worlds.

As for Wu Yu and Black Yama Demon King, as well as the eternal demon emperor corpse, the were thrust into Wu Yu's void world, created by his Somersault Cloud. The opponent's black sea heavenly rule had also disappeared into goodness knows where, whirled away by Wu Yu's Mystique.

However, Wu Yu could only force a Void Reversal on Black Yama Demon King thanks to the power of Immolate Ultimus. If not for Immolate Ultimus, this Void Reversal would not be effective against such a strong opponent.

Therefore, Wu Yu was not in a good position. He had barely managed to negate the last attack. If the opponent pressed his advantage and attacked again, Wu Yu might not be able to defend against this one.

Therefore, there was something he had to do now.

As Black Yama Demon King's heavenly rule power was broken, Wu Yu seized his chance and sped over to the eternal demon emperor corpse. The terrifying face of the Heaven Devouring Titanic Beast chomped savagely down on the eternal demon emperor corpse.

He needed the essence of the eternal demon emperor corpse to replenish what he had lost through Immolate Ultimus!

The huge corpse would definitely take some time to harvest completely. It could not be easily put into a sumeru pouch.

However, just taking a few bites was a simple enough feat.

From the first bite, the robust vitality and corporeal essence flooded his body!

The Heaven Devouring Titanic Beast was looking a little slumped. After chomping down on the eternal demon emperor corpse, it immediately recovered.

"What are you doing? Get down here to Father Yama!"

Black Yama Demon King flew into a rage as he saw what Wu Yu did. In his mind, the eternal demon emperor corpse was already his. And now seeing Wu Yu take the first bite made him furious.

However, he was not yet despairing. The way he saw it, Wu Yu might have taken a bite, but he could not possibly digest it immediately.

As long as he killed Wu Yu and devoured the unknown beast that was Wu Yu, he might be able to get back a portion of it.

Of course, he had to move quickly, and finish Wu Yu off as promptly as possible.

However, he realized that after biting down on the eternal demon emperor corpse, Wu Yu's Heaven Devouring Titanic Beast seemed to recover its former strength!

His entire body was burning energy, and yet his inner energy was not at all diminished. Instead, it was growing stronger!

This constantly strengthening and growing aura made Black Yama Demon King feel threatened!

This unsettled Black Yama Demon King. It was just an Immortal Lord Realm punk before him. Simply changing into this strange beast form could cause such a threat?

What a bizarre existence!

"No matter what, you must die today!"

Black Yama Demon King thundered. His own octopus tentacle started to wriggle. While Wu Yu was still eating the eternal demon emperor corpse, he finally attacked!

It was already unbelievable that his first attack had not succeeded. This time, he could not give Wu Yu any more chances.

"Baleful Yin heavenly rule!"

Baleful Yin qi began to gush forth from Black Yama Demon King's tentacles, speeding towards Wu Yu.

This was just like the Baleful Yin qi that held the many demon kings outside. Of course, Black Yama Demon King's Baleful Yin qi was not as strong as the one from the eternal demon emperor corpse.

But even so, this Baleful Yin heavenly rule was completely directed at Wu Yu and Wu Yu alone!

Therefore, as the Baleful Yin qi manifested as heavenly rule power, Wu Yu felt as though he were submerged in a swamp!

In this swamp, there were innumerable worms biting away at his body.

Such was Baleful Yin heavenly rule. Its destructive power might only be average, but it could definitely hold Wu Yu completely!

After all, Wu Yu's masculine yang energy was dominant in his body. It was the ultimate temptation for Baleful Yin qi.

A pity that Black Yama Demon King did not know that Baleful Yin qi was all but useless when Wu Yu was in the Heaven Devouring Titanic Beast form!

Caged by Baleful Yin qi, his battle strength was only slightly diminished, and the Baleful Yin qi did not harm him whatsoever.

Therefore, he continued to gorge on the eternal demon emperor corpse. There were already many wounds on the eternal demon emperor corpse!

Most of the corpse had already been devoured by Wu Yu and converted into pure life energy within him. Wu Yu was still burning and burning energy!

If he wanted to defeat Black Yama Demon King, he would have to nail it in one. He only had one chance. For Immolate Ultimus, his own internal energy was insufficient. He also had to immolate a part of the eternal demon emperor corpse's life force.

His aura and strength continued to burn stronger and stronger, until he neared a critical point!

He was probably ready to try and finish Black Yama Demon King in one hit.

This was the most thorough Immolate that he had ever used.

After all, with a treasure trove of energy in the eternal demon emperor corpse before him, he could afford to be reckless!

As for Black Yama Demon King, he had already assumed that his own Baleful Yin heavenly rule would completely shut down Wu Yu.

Within the dark cloud of Baleful Yin qi, Wu Yu's signature seemed diminished, and that was well within Black Yama Demon King's expectations.

He planned to use his next heavenly rule to finish off Wu Yu in one blow!

After all, Baleful Yin heavenly rule was only a suppressing maneuver. He would still need one more heavenly rule to finish off Wu Yu.

He wanted to use his heavenly rule, death ray heavenly rule. As his many tentacles stretched out, a dark light began to materialize. This was Yin darklight, Black Yama Demon King's strongest killing technique.

First the suppression, and then the killing blow. That was the standard method that Black Yama Demon King adopted!

This Yin darklight coalesced in a flash, preparing to fire out towards the Baleful Yin qi.

But just at this moment, Wu Yu had already reached a critical point within the void world. His constant Immolation had allowed his ability to reach a new and frightening limit.

Although he had been constantly devouring the eternal demon emperor corpse, but the drain on Wu Yu was still fairly huge. He would require a few thousand years to recover. But in order to finish off Black Yama Demon King and obtain the eternal demon emperor corpse, he was willing to risk it.

After using Immolate Ultimus, his Somersault Cloud had also reached peak power.

"Violent Art!"

With the additional boost from Violent Art, Wu Yu's strength was too prodigious to comprehend. Even Black Yama Demon King was shocked.

But before Black Yama Demon King could truly act and send the Yin darklight towards him, Wu Yu's attack flew out first!

Submerged Cloud Seal Mystique absorbed the autonomous realm power of the void world, and then blasted out towards Black Yama Demon King.

Combined with Violent Art, Submerged Cloud Seal was the strongest attack that Wu Yu had unleashed ever!

This attack of his disintegrated the void that Black Yama Demon King was in, and his prepared death ray heavenly rule also vanished without being fired.

Black Yama Demon King was in agony and disbelief. The ponderous black octopus body was shredded by Submerged Cloud Seal's void explosion, imploding. He died in a bizarre and painful death!

Perhaps Black Yama Demon King had never considered that he would be finished off by some Immortal Lord Realm small fry. Therefore, he had not deployed any defenses. This allowed Wu Yu's peak Immolate Ultimus and Violent Art together to finish him in one blow.

As the void world faded, Wu Yu returned back to the black sea. The eternal demon emperor corpse was still by his side, but the Baleful Yin qi of Black Yama Demon King had faded now. His octopus body had been blasted to chunks, and Wu Yu did not let it go to waste. He ate that too.

Currently, Wu Yu was extremely weakened due to Immolate Ultimus. Next, he would harvest the eternal demon emperor corpse and then quickly leave.
