Luckily, Wu Yu had taken the precaution of fighting in only the Heaven Devouring Titanic Beast's form. This meant that the disappearance of Diabolical Dragon King and Taotie Demon King could not be linked to him.

While it was inevitable that they would be seen while wandering Demon Immortal Realm, the demon immortals they encountered were all weak, and scurried away upon seeing the mighty pair. However, if they were recognized, word would definitely get back to Unending Demonic Emperor.

Both Wu Yu and Wu Jun were traveling in their human forms, and so the demon immortals would not raise the alarm on them even if spotted.

While roaming Unending Demonic Empire, they heard whispers of Diabolical Dragon King and Taotie Demon King's deaths, but no one could prove it. Firstly, no one had found their corpses, and secondly, there was no sign of a culprit at all.

Sometimes, they even heard speculation that Unending Demonic Emperor had personally gone in search of people connected to the affair, but had not succeeded either.

Therefore, Wu Yu's party was still rather relaxed.

Before they knew it, 5000 years had passed.

In these 5000 years, Wu Yu had lingered in Demon Immortal Realm, while Wu Jun occasionally returned to the sky palaces, in order to quell suspicions and avoid trouble. He could also check in on Luo Pin.

Each time Wu Jun returned to the sky palaces, Wu Yu was most keenly interested in the news of Luo Pin that he brought with him. Wu Jun himself could not meet her, but he knew that she was cultivating in seclusion, and unable to go out.

A few times, Wu Yu had Wu Jun ask about Nangong Wei. Unfortunately, she too was shut away, and there was no news of her.

Wu Yu had been away from the sky palaces for a long time, but he was still on the minds of too many eternal immortal emperors in the sky palaces. Even if he appeared after hundreds of thousands of years, he would definitely raise a storm.

Therefore, he could not go back for now.

But after wandering Demon Immortal Realm for so long, he had not succeeded in finding any eternal demon emperor corpse, although he and Wu Jun had searched high and low, and even into the depths of the void chasms. There had been no news on the annihilation at Demon Immortal Realm either.

One day, Wu Jun had just returned from the sky palaces via Ancient Demon Realm, and he had passed by Peak of the Granular Wooden Realm.

Wu Yu had been waiting for him, but the moment Wu Jun appeared, his face changed. "Not good. Who's been watching us? Show yourself!"

Wu Yu had been here a long time, but oblivious. Wu Jun immediately sensed upon his arrival that they were being watched!

He had just come from the Ancient Demon Realm. If they were seen, it would be easy enough for the unknown person to realize that they had a way to leave Demon Immortal Realm. It would be big trouble if this secret was exposed!

Wu Yu's face stiffened as well. He had been waiting for Wu Jun all this while, but had not noticed that they were being watched.

It was not due to his incaution. He had been observing his surroundings carefully, but clearly their observer was of a high level, so much so that even Wu Jun had only caught a faint trace.

A completely invisible presence. As Wu Jun fired his heavenly rule power in the direction, a shapeless body of water appeared from all around them, surging into sight with a strong demonic aura!

"A sea turned demon?"

Wu Yu and Wu Jun's faces tightened. Wasn't this the Unending Crepuscular Sea, the true form of the Unending Demonic Emperor?

Could it be that this was the Unending Demonic Emperor himself?

But if that was the Unending Demonic Emperor, a 9-heavens demon king would not have been skulking around, but would definitely have looked to deal with Wu Yu actively, and leave the Demon Immortal Realm.

Therefore, this being should not be the Unending Demonic Emperor, but simply a being similar to him.

"No wonder Taotie Demon King and Diabolical Dragon King have been missing lately. You must have done them in. You can actually enter and leave Demon Immortal Realm at will. Wonderful. Wonderful!" The thing shrieked gleefully, as if it had discovered a great secret.

"Who are you?"

Wu Jun demanded, at the same time covertly preparing his own techniques.

"I am the Fathomless Starry Sea, a great general under the Unending Demonic Emperor! You two immortals are exposed now. I advise you to turn yourselves in to the demonic emperor. He will definitely treat you well! Otherwise, there is no place in the Demon Immortal Realm that you can hide from our demonic emperor master!"

The demon said shrilly.

Fathomless Starry Sea was a being like the Unending Crepuscular Sea. He was an 8-heavens demon king and could change his body shape at will. His concealment abilities were even more refined than the Bloodsucking Scourge's. As shapeless water, he was completely silent and showed no trace.

If not for Wu Jun being at the 9-heavens immortal king level, he would probably have gone undetected.

This meant that if Fathomless Starry Sea hid himself, only the five demonic emperors could find him in the Demon Immortal Realm. Unending Demonic Emperor was lucky indeed to get such a fine general under him.

"Dragon Breath heavenly rule!"

Wu Jun suddenly struck with the attack that he had been preparing. His virulent power hurtled towards Fathomless Starry Sea, and struck him square on!

However, the opponent's body simply split apart into two seas, and Dragon Breath heavenly rule whizzed by ineffectively.

Although Dragon Breath heavenly rule had intense destructive power, but it first had to connect. Far in the distance, a mountain was reduced to rubble. But right before their eyes, Fathomless Starry Sea was unharmed and unfazed!

Wu Yu had not been standing idle either. As Wu Jun attacked, he too used Submerged Cloud Seal. The void within his opponent's body burst!

Again, Fathomless Starry Sea dissolved into water droplets, which scattered on the floor. If these water droplets could not be completely dispersed, Fathomless Starry Sea could not die.

Wu Jun and Wu Yu had both attacked simultaneously, but their attacks had been dodged by this body splitting ability. Shrill laughter haunted them, and Fathomless Starry Sea vanished, the water droplets disappearing. Neither Wu Yu nor Wu Jun knew where or how to chase him.

Wu Yu even tried his Unshackled Doppelganger, sending out his 1 million doppelgangers to continue attacking the water droplets. They were able to further divide into tinier particles of water that fled everywhere. Not even 1 million doppelgangers could contain him!

A sea turned demon, and now able to divide into water droplets. There must be millions of them!

And these millions of water droplets showered all around them. They could not possibly catch him!

That was why Fathomless Starry Sea had been completely unhurried. He was very confident in his own escape abilities to extricate out of trouble.

"He got away."

Wu Yu was not happy about it. He called back his 1 million doppelgangers, an ugly expression on his face.

Now that Fathomless Starry Sea had gotten away, word would definitely spread across the whole of Demon Immortal Realm!

Firstly, they had killed Diabolical Dragon King and Taotie Demon King. This was enough reason for Unending Demonic Emperor to come after them. Secondly, they were strangers, immortals. Immortals could not appear at Demon Immortal Realm.

Although Fathomless Starry Sea had only seen their appearances, but he could guess. If they did not have a way to leave Demon Immortal Realm, why would they come to a barren and hopeless Demon Immortal Realm?

"We had best hide for a while. If we hide really well, they won't be able to find us."

Wu Yu and Wu Jun knew they were in trouble, but they were not that frightened. Demon Immortal Realm was vast, and it would be very difficult for them to be found. As long as they kept their heads down and only searched for the eternal demon emperor corpses discreetly, chances that they would run into other demon immortals was low.

They needed Full Moon of Nanshan to come out now. Through his Gone from the Skies Mystique, he could elude the eyes of everyone in the Demon Immortal Realm. His concealment skills were even better than Fathomless Starry Sea's.

Therefore, before Wu Yu and Wu Jun moved on, they sent Full Moon of Nanshan ahead to scout. If there were no demon immortals, they would continue ahead. If there were, they would either make a detour or rest where they were, biding their time to move on.

In this way, it was all but impossible for them to be found.

Besides, with Wu Jun around, there would be no chance that Fathomless Starry Sea could hide nearby without being detected.

Wu Yu believed that no one in Demon Immortal Realm could hide as well as Full Moon of Nanshan.

For now, Wu Jun could not leave Demon Immortal Realm either. He had to continue staying by Wu Yu's side, or risk subjecting him to detection. If Fathomless Starry Sea came rolling up and Wu Yu was oblivious, he would be in great danger.

Besides, there were five demonic emperors in total. If they joined forces, the two of them were doomed.

......

At the same time, in a wide space somewhere else in the Demon Immortal Realm.

A towering golden mountain appeared out of the void, landing in the midst of the vast plain. This was the demonic emperor of Olden Demonic Empire, Olden Golden Mountain!

As Olden Demonic Emperor appeared, a dark sea came rolling by soon after, seeming to stretch all the way to the horizon. This was the Unending Crepuscular Sea, Unending Demonic Emperor!

From three other directions, similarly impressive sights were stirring. With rumbling of sky and earth, the five demonic emperors had actually gathered together!
