Wu Yu was now formally a 7-heavens immortal king, although his actual prowess far exceeded that.

Wu Yu reckoned that if he had met Diabolical Dragon King or 10,000 Eyed Taotie in Demon Immortal Realm at his current prowess, he could kill them all with one hand tied behind his back. Even if the five demonic emperors of the Demon Immortal Realm came at him together, they would be no match for him, and he might even kill them all.

Although the tests in the Eternal Emperor Tomb had not resulted in much of a cultivation realm increase, but his actual fighting strength had improved greatly.

Just the fight against his mirror-self in the Place of Overcoming had multiplied his fighting strength many times over, and he had just gone through another 5000 years of intense cultivation. Although he had but increased one cultivation realm in this time, but he had firmed up all of his Mystiques again, and his strength had again surged.

If he could only run from eternal immortal emperors before, now he should have the strength to withstand one.

Still, it would not be easy to defeat one. Then again, in his last 4000 years of cultivation, Wu Yu had managed to gain insights on his eighth heavenly rule, Dao of the Void. Although it had yet to be finished as a heavenly rule and allow him to become an 8--heavens immortal king, but it was still a source of strength.

Therefore, Wu Yu still had a measure of confidence in fighting Empyrean Revered Dragon.

"Wu Yu, how confident are you for this fight?" Baiyin Dragon King asked him three days before the big event.

"Empyrean Revered Dragon is an eternal immortal emperor, and I think it very difficult to defeat him. Then again, it's impossible for him to defeat me either. Only time will tell." Wu Yu admitted.

"Alright, as long as you stay safe. Even if you fail this time, you're still young. When you become a true eternal immortal emperor, the dragon elders will not cause you trouble either." Baiyin Dragon King cautioned.

Baiqin Dragon Queen rolled her eyes at him. "Didn't you hear Wu Yu? Even if he can't defeat Empyrean Revered Dragon, Empyrean Revered Dragon can't defeat him either. That means it will be at worst a stalemate. Don't fuss."

"Even if it's a draw, the pact won't count!"

Baiyin Dragon King was still a little worried. "Don't pressure yourself too hard about this fight, alright? Your life is more important than anything else. Against an eternal immortal emperor, watch yourself carefully." He advised.

"I understand."

Wu Yu nodded solemnly.

He noted well the couple's deep concern for him. Luo Pin included, they were all hoping that he could beat Empyrean Revered Dragon. How could Wu Yu let them down?

No matter what, he would win this battle at all costs!

Otherwise, Wu Yu would be unable to forgive himself.

He had the legacy of the Great Sage, Heaven's Equal. Although he had yet to defeat an eternal immortal emperor before, but that was only a matter of time. Time would continue on forever. Who could say for sure?

If it had never been done before, then he, Wu Yu, would be the first!

Wu Yu would not accept defeat, and his confidence was bolstered by the Great Sage, Heaven's Equal's legacy. With a name like the Victorious Fighting Buddha, how could he be afraid of any fight?

Empyrean Revered Dragon was not considered one of the strongest. An ordinary eternal immortal emperor was just what Wu Yu needed.

It was not his first time facing off against an eternal immortal emperor, although all his past encounters had been against corpse puppets and the like, and more fleeing than fighting.

As the fight day neared, Wu Jun came looking for Wu Yu, and spoke gravely to him. "Wu Yu, what do you know about eternal immortal emperors? Do you know what strength they have?"

Wu Yu did not. He only knew that they were very strong, and had eternal life. Besides that, he knew nothing at all about the source of their strength.

Clearly, this was what Wu Jun was coming to tell Wu Yu about, so that he could know his enemy, and not fall to an unfamiliar strength.

"Please tell me."

Wu Yu perked up. Wu Jun had spent the last 5000 years firming up his first eternal immortal emperor tier, primarily honing the unique strength of the eternal immortal emperors.

Wu Jun explained the details to him.

The eternal immortal emperors' strength came from the Apotheosis Realm, which surpassed even the immortal dao.

Within each eternal immortal emperor's body, there was a huge world which would endure for eternity. This was the Apotheosis Realm, a world within their bodies that generated their strength.

"For example, Empyrean Revered Dragon's body holds the Empyrean Apotheosis! It is a true lesser realm within his body. It is a genuine world complete with skies and seas. In his body, life will be born, mortals will cultivate, and through this process, generate apotheosis immortal energy!"

Wu Jun continued to explain. So there was the equivalent of a lesser realm in each eternal immortal emperor's body. The power of all life within that lesser realm was strength that the eternal immortal emperor could draw upon. It far exceeded the immortal energy within an immortal's own body.

And the Mystiques that the apotheosis immortal energy fueled were all complete. They were called apotheosis Mystiques!

All of their dao techniques, when executed with apotheosis immortal energy, were called apotheosis immortal techniques!

All of these far surpassed an ordinary immortal's techniques. This was the real reason why an ordinary immortal would be unable to fight an immortal emperor. They had already reached eternal life, and created a self-sustaining world within themselves, a source of terrifying power.

Apotheosis immortal energy, apotheosis Mystiques, and apotheosis immortal techniques - they were all beyond imagining for anyone who was not an eternal immortal emperor.

And as an immortal emperor continued to cultivate, and existed for a longer time, the mortals in the lesser realm within their body would continue to multiply and grow stronger. All this was then converted into the immortal emperor's own strength.

Although each mortal's strength was puny and insignificant compared to an immortal, but there were so many of them! Even the flowers and trees, the pests, the birds, the beasts - all of it was at the immortal emperor's disposal!

"There are 90,000 lesser realms in the Heavenly Domain. They wouldn't have all been created in eternal immortal emperor bodies, would they?"

Wu Yu blurted out unsteadily.

"That's exactly right. All the 90,000 lesser realms were all immortal emperors who passed away before, only leaving behind the lesser realms in their bodies. The mortals and life remain in them."

Wu Jun continued: "And each living immortal emperor has a lesser realm inside them as well. For example, the lesser realm in Empyrean Revered Dragon is called Empyrean Realm by the mortals inside, although they do not know that they are actually living in an immortal emperor's body."

"I see it all now!" Finally, Wu Yu understood the essence of an immortal emperor.

So one had to open the void within oneself, and fashion a lesser realm. Only then could one reach the eternal immortal emperor realm. Inside, one would allow life to flourish, and all of them were the eternal immortal emperor's people, and they in turn became his strength.

The Heavenly Domain had persisted for ages, and countless eternal immortal emperors had died before, leaving behind new lesser realms as a hotbed to produce new generations of immortals.

This meant that apotheosis Mystiques and apotheosis immortal techniques had overwhelming power which would trump ordinary heavenly rule power without a doubt.

Wu Jun's words gave Wu Yu a general understanding of Empyrean Revered Dragon's power. It was as if he was fighting an entire lesser realm!

The difficulty was incredible, but Wu Yu believed in himself. Having come this far, he could not afford to back down. He could only push on, and make a world for himself and Luo Pin.

The only way he could prove himself was through battle.

If he failed here, then there would not be many options left to him. Best to win, even if his opponent was Empyrean Revered Dragon himself. Even if he had to go against the combined life force of an entire lesser realm. Even then, forwards.

"Don't give yourself too much pressure. Whether youw in or lose, I will be with you till the end. At most, we would have to leave together, and go back to Demon Immortal Realm to weather the storm."

Before he left, Luo Pin leaned against Wu Yu, soothing him with calm words.

"You don't worry either. I will definitely win this battle, so we can continue our relationship openly!"

Wu Yu said, his face the very picture of solemnity. Taking her hand, he headed towards Saintly Dragon's Domain together with Wu Jun.

The place of battle had been determined as Saintly Dragon's Domain. Therefore, only the 9 Great Dragon Emperors and the Revered Dragon Council could watch the fight.

Although it was a fight between their juniors, but it involved Luo Pin, the heir to the Dragon Ancestor's legacy. Besides, this battle was between Wu Yu and Empyrean Revered Dragon, a seemingly impossible match-up. All of the Revered Dragon Council were present.

Besides the ancestral worship festival, there were very few events which could gather all of the revered dragons, a testament to how seriously this battle was being taken.

Besides the dragon emperors, revered dragons, Wu Yu, and Luo Pin, the rest of the mystical dragon tribe could not enter to watch.

In truth, many of the other ordinary mystical dragons did not even know that Wu Yu was in Immortal Dragon Imperial Realm. If the news had leaked, Primeval Mighty Miracle God and the others would probably have come knocking even before the battle had taken place.

Very quickly, Wu Jun led Wu Yu and Luo Pin to Saintly Dragon's Domain, where they had first reunited this time round.

Here, Wu Yu would fight Empyrean Revered Dragon in a crucial battle!

With all eyes on him, Wu Yu flew up into the void alone, resolution hard in his eyes, reinforced with a battle will that would never accept defeat.

Unfortunately for him, the dragon emperors and revered dragons did not look favorably on his chances.
