Wu Yu was experimenting with epochal immortal designs in the Eternal Emperor Tomb. He soon discovered that the difficulty was immense, and not something that could be done in a day.

"There are no secrets left in the Eternal Emperor Tomb now. Let's go."

Wu Yu felt a tinge of regret. These epochal immortal designs were too abstract. Even with the bronze ball guiding him, it was not so easy to master them immediately. He decided to put them aside for now. There was no rush.

"Where... can we go?"

Full Moon of Nanshan was a little glum, not having had "some" for a while now. But following Wu Yu meant a life without skirt chasing, which he had enjoyed fully in the sky palaces.

Of course, he had no complaints on the whole - Full Moon of Nanshan was still quite a serious person.

"Shall we head back to the sky palaces for a bit?"

Wu Yu called Wu Jun over to discuss: "At least given my current ability, if some of the eternal immortal emperors like Mighty Miracle God come chasing, I might not be able to beat them, but escaping should not be a problem. I can even hide in the Floating Dreams Pagoda. If all goes well, they won't even know that I'm there."

Wu Jun thought it over, and nodded. "Works as well. After being away for so long, I should go back for a look. I'll just take the Floating Dreams Pagoda with me, and you lot can wait inside."

Wu Jun too knew that a big motivation for Wu Yu wanting to go back was Luo Pin.

He had not seen her for too long. Since that incident, she had been completely missing from his life, save his dreams.

"I'm not just aiming to see her, but I also want to take her away. After all, she will improve much more quickly with me." Wu Yu still had many more legacies that he could Impart to others to speed up their cultivation.

This skill allowed his companions to improve far quicker than others.

"Of course, there are also two more things. First is to ask Nangong Wei why she did what she did back then."

Wu Yu said, and then a queasy look entered his eyes. "Second is to see if there are any clues left in the sky palaces. Best if confirmation can be obtained, as to whether Demon Immortal Realm was finished off by the heavens and hells."

On his cultivation journey, Wu Yu had never had cold feet when the situation called for him to be merciless. However, he was fundamentally a good person.

Billions of lives wiped out on Demon Immortal Realm, and the realm devastated. The goodness within him cried out for justice, for the perpetrators to be brought to justice.

This might even be tied to the reason that he received the Great Sage, Heaven's Equal's legacy.

The Great Sage, Heaven's Equal, Marshal Tian Peng, Curtain Lifting General, and Eight Division Heavenly Dragon. These four were eternal immortal emperors that have been clean forgotten. What was happening?

There must be an enormous secret around here. It might all be linked!

After some discussion, they decided to return to the sky palaces.

Of course, they had to leave someone here in the Demon Immortal Realm.

"Let's go back to Demon Immortal Realm first." Wu Yu said, gesturing with the bronze ball in his hand. The bronze gates appeared out of thin air, swinging open.

They left through the door, and found themselves back at the place where they had first entered into Eternal Emperor Tomb.

The entrance was where the exit was.

And the key to the door was the bronze ball that Wu Yu was holding. This epochal immortal treasure was the key to the entire Eternal Emperor Tomb. A pity that Wu Yu could not use its full strength yet.

WIthin the Floating Dreams Pagoda, Full Moon of Nanshan and Ye Xixi were resting.

Only Wu Yu and Wu Jun were outside. They returned to the Demon Immortal Realm, and found themselves surrounded by a horde of Great Void Demon Immortal Realm demon immortals! They totaled up to more than 300 demon kings ranging from the 6-heavens to 8-heavens cultivation level!

These were all the subordinates of the five demonic emperors. They had decided to guard this spot when the demonic emperors had vanished.

They were certain that someone would eventually emerge, be it Wu Yu or the five demonic emperors. They had to know - what had happened in the Eternal Emperor Tomb?

And after all these years, their patience had finally been rewarded.

However, their appearance roused a commotion. Of the five demonic emperors, there was nothing to be seen. Instead, it was Wu Yu and Wu Jun, the two immortals, who emerged!

What was going on?

The hundreds of demon kings were unafraid of Wu Yu and Wu Jun, and came crowding up. They planned to question him as to the fate of the demonic emperors, and the happenings in Eternal Emperor Tomb.

But before they could close in on him, Wu Yu immediately pulled Perpetual World Tree out of the Floating Dreams Pagoda.

Perpetual Demonic Emperor had been living in fear within Wu Yu's Floating Dreams Pagoda. He did not know if death would come. He had been completely reliant on Wu Yu. Wu Yu's death would mean his death.

He did not expect to be able to see daylight again so readily, and shining down on a familiar Demon Immortal Realm at that!

As Perpetual Demonic Emperor appeared, hot tears of relief filled his eyes at seeing the hundreds of demon kings.

The five demonic emperors had entered the Eternal Emperor Tomb together, and in the end only he had made it out alive. He was indeed a little nostalgic about it. After all, the other four had been his rivals or allies for countless eons. And now they were gone.

"What...... is happening?"

The demon kings milled around, confused. If it had been just Wu Yu and Wu Jun, they would have started fighting immediately.

But Perpetual Demonic Emperor was now in their midst. They had found a beacon to rally around. Whatever Perpetual Demonic Emperor said, they would do.

As Perpetual Demonic Emperor emerged, he was rather respectful towards Wu Yu.

Although he did not know what had happened in the Eternal Emperor Tomb, but he knew that he alone was no match for the pair combined.

Besides, Wu Yu managing to leave Eternal Emperor Tomb meant that he might have gotten even more legacies or treasures to improve even further.

Perpetual Demonic Emperor did not dare to slight Wu Yu. He first had the other demon kings disperse back to their lands, then finally swung back to Wu Yu, beaming. "Alright then prince. What are your plans?"

Perpetual Demonic Emperor wanted to know how Wu Yu would deal with him.

Wu Yu was not planning to do anything in particular. He spoke frankly: "The Eternal Emperor Tomb is in my control. I'm sure you know too well how much I've grown from it?"

"I do! I do!"

Hearing this, Perpetual Demonic Emperor immediately cowered. In human form, his eyes were filled with trepidation. He knew what the Eternal Emperor Tomb held. If all of the eternal immortal emperor corpses had been mastered, then Wu Yu would be well into the eternal immortal emperor realm, right?

In which case, he would be leaps and bounds ahead of himself. He could not hope to contest!

So the kid had actually taken all of their assets in the Eternal Emperor Tomb......

Perpetual Demonic Emperor did not dare doubt Wu Yu's words. After all, Wu Yu's successful emergence from the Eternal Emperor Tomb said all.

"The prince's wish is my command!" Perpetual Demonic Emperor asserted his subservience.

Wu Yu had originally already been stronger than him, let alone after mastering the Eternal Emperor Tomb. He would probably continue to surpass him more and more from hereon......

Was what Perpetual Demonic Emperor thought.

Therefore, he was willing to obey Wu Yu. Besides, now that the other four demonic emperors were dead, he was the only 9-heavens demon king in the whole of Demon Immortal Realm. He could be the sole ruler.

In such a situation, being second-in-command to just Wu Yu was not a bad deal.

Besides, he knew that Wu Yu and Wu Jun had come from the sky palaces. They might not remain here. Maybe Wu Yu would even take him out of Demon Immortal Realm......

"This Jiu Ying is my friend. He wants to stay at Demon Immortal Realm. You will protect him well. If you acquit yourself, I can consider taking you away with me to the sky palaces." Wu Yu let Jiu Ying out of the Floating Dreams Pagoda, introducing him to the Perpetual Demonic Emperor.

Jiu Ying wanted to stay at Demon Immortal Realm for now. After all, he was a demon immortal, and wanted to remain here.

And so Wu Yu had made Perpetual Demonic Emperor his guardian. That way, he could not possibly come to harm here in Demon Immortal Realm.

"Your servant obeys!"

Hearing that he had a chance to leave effused Perpetual Demonic Emperor, even humbling himself down to "servant". That was how much he longed to leave the Demon Immortal Realm.

He had entered the Eternal Emperor Tomb and seen many eternal demon emperor corpses turned into corpse puppets. This made him feel like the Demon Immortal Realm was a cursed land, and there might be many accidents lurking in his future if he remained here.

Therefore, leaving was the best option, and Wu Yu his only option to do so.

"Rest assured that from now on Prince Jiu Ying is my most important priority. Anybody who wants to lay a finger on him will have to ask my consent!" Perpetual Demonic Emperor vowed fervently.

This satisfied Wu Yu. The temptation to leave Demon Immortal Realm was quite strong, and Wu Yu was assured of his compliance.

"Finally, best seal off this entire area, and keep the other demon kings away from it."

After some fiddling around, Wu Yu realized that the bronze ball could make the entrance to the Eternal Emperor Tomb appear or disappear at will.

However, the entrance was right here, and the bronze ball was but a key.

If he wanted to come back to Eternal Emperor Tomb, he would still have to come to Demon Immortal Realm.

Therefore, Wu Yu did not want the other demon kings to meddle and cause any problems.

Perpetual Demonic Emperor naturally acceded to this.

Perpetual World Tree took his leave first. He had the entire Demon Immortal Realm to reorder, to assert his foremost position.

As for Wu Yu and the others, of course they intended to return to the sky palaces.
