The trio looked at one another.

Wu Yu questioned, "You are certain that the rumors said this place was destroyed by the immortals?"

Su Muyin was a little anxious. "That's what the majority of the people are saying. However, there's also a small portion of people claiming that it was destroyed by the ghostly immortals from Hell. There's also a portion of people claiming the immortals worked with the ghostly immortals to destroy this place. This was because they were jealous that the Demon Immortal Realm was larger and fertile with robust demonic immortal qi. I heard the Demon Immortal Realm was beautiful in the past. However, only the ruins remain now."

This sounded unbelievable. To his knowledge, the immortals and ghostly immortals currently had minimal understanding of the Demon Immortal Realm. As for eternal immortal emperors, they probably knew more.

"Was these done secretly by the eternal immortal emperors and eternal devil emperors?" Wu Yu conjectured.

However, if Demon Immortal Realm was so humongous previously, how could it be destroyed without causing a commotion in the sky palaces and hell?

"These are the rumors that I've heard over the years. I'm sorry, seniors. I don't know the real truth......" Su Muyin answered apologetically.

Wu Yu didn't want to make it difficult for her and it's natural that they had their doubts.

Full Moon of Nanshan asked, "To destroy the Demon Immortal Realm to this state, it would at least be by the most elite immortals or ghostly immortals. The Five Directional Divine Emperors probably couldn't achieve it. Didn't the eternal demon emperors resist? There was bound to be some commotion caused?"

Su Muyin shook her head and answered, "There aren't any eternal demon emperors. It was said that they had all died in battle!" All three of them exclaimed.

This was the Demon Immortal Realm, the equivalent of 8,000 Sky Palaces or 10,000 Levels of Hell. Currently, there were numerous eternal demon emperors and eternal immortal emperors in hell and sky palaces. All of them enjoyed eternal life.

As such, the number of eternal demon emperors shouldn't be few.

Yet, she said all the eternal demon emperors had died in the battle of destruction.

"How is this possible? All of them died in that battle? After all these years, there isn't any new eternal demon emperor in the Demon Immortal Realm?"

The trio asked anxiously.

Su Muyin nodded and said, "That should be the case. It is at least so for the 60,000 years that I've been here. The truth is...... You wouldn't believe what I'll be saying. I heard that it wasn't just all the eternal demon emperors that had in that battle. All the demon immortals in the Demon Immortal Realm were killed. Not a single one survived. All living creatures were exterminated from this world."

Upon hearing, Wu Yu and others thought she was joking.

How many immortals were there in the sky palaces?

How many ghostly immortals were there in hell?

Disregarding all 8,000 Sky Palaces, the immortals on just the first level of Heaven were immeasurable.

The demon immortals in the Demon Immortal Realm would likely be about the same.

All of them died in that castastrophic battle?

How many lives would have been lost in that battle? How frightening would that annihilation be? What kind of ruthless existence could possibly commit such an act!

This was the genocide of an entire race!

"Are you joking?" Ye Xixi voice was cracking.

Su Muyin answered anxiously, "Sister senior, I definitely wouldn't dare to joke with you. However, this is what I've heard and they are rumors. After all, we have not been through it. If you encounter other demon immortals, they would definitely tell you the same. I really have no idea who caused the war. However, in the 60,000 years that I've been here, I have never heard about anyone who survived that battle."

Wu Yu kept his calm.

"What you are saying is that all the demon immortals in the Demon Immortal Realm currently have ascended from the mortal domain since that battle?"

Su Muyin nodded and answered, "Yes. All of us are. Therefore, there aren't many of us. The Peak of the Granular Wooden Realm is even larger than the lesser realm within the mortal domain that I was from. However, there's only a few demon immortals in total."

Upon hearing, the trio couldn't regain their composure for a long time. They had never expected the Demon Immortal Realm that was only known by many in legends had been through an event like this.

Full Moon of Nanshan heaved a sigh. "It seems like this world isn't as simple as I've thought. The secrets behind it are still plenty."

Wu Yu nodded in agreement.

The eternal immortal emperors of the sky palaces were behaving like nothing had happened.

However, how could they not be aware that the Demon Immortal Realm was destroyed and the living creatures on it were exterminated?

If they weren't behind it, who would be? Wouldn't anyone be anxious?

Moreover, he recalled no one remembered Great Sage, Heaven's Equal and others. Even memories of the Dragon Ancestor was vague for Sky Heart Dragon Emperor and others. What did the Great Sage, Heaven's Equal mean when he called them puppets?

The mist seemed to be thickening.

It was today that Wu Yu realized there were many unfathomable and frightening secrets behind the Heavenly Domain.

In this colossal Demon Immortal Realm, the current existing demon immortals had all ascended since the destruction.

It's not hard to explain why a huge place like the Peak of the Granular Wooden Realm would only have so little demon immortals. If an area this huge was in the sky palaces, it would host at least trillions of immortals. In this place, there were only several demon immortals.

Moreover, the immortal qi was scaringly thin. There didn't seem to be any bountiful land too.

In 60,000 years, Su Muyin had only reached the third tier of the Longevity Demon Realm. Her progress in the future would be arduous as well. As compared to the 3,000 greater realms of the mortal domain, this was only several times better. This couldn't be compared to the sky palaces or hell at all!

"Who destroyed this world?"

The trio couldn't understand.

Would these mysteries be intertwined with Great Sage, Heaven's Equal, Marshal Tian Peng, Curtain Lifting General or the Eight Division Heavenly Dragon?

They had no idea as well.

After half a day, they finally calmed down.

"The current Demon Immortal Realm is the wrecked place we saw. All the demon immortals have ascended from the mortal domain. They hide themselves while cultivating silently. At this moment, not a single demon is able to become new eternal demon emperor, right?" asked Wu Yu.

Su Muyin nodded and answered, "You are right. How could they achieve eternal life. The demonic immortal qi in this place can't be compared to the sky palaces. It's hard even for the new eternal immortal emperor to be born in the sky palaces, right? Nonetheless, there are several elite demon kings that rule the current Demon Immortal Realm. In normal times, they live in harmony. Only occasionally would they fight over scarce resources."

This was just a pitiful world after its destruction.

Subsequently, Wu Yu found out more about the experts of this place. The strongest among them were at the pinnacle of the Great Void Immortal Realm. They were absolutely unprecedented geniuses to reach the brink of becoming eternal demon emperors in a place like this.

If any of them could become eternal demon emperor, he would be the new ruler of the Demon Immortal Realm.

However, the issue was that the Demon Immortal Realm was destined to doom. Even if they became the new ruler, it wouldn't be of any use.

Moreover, if they couldn't leave the place, they could only vanish with the world even if they were demon emperors.

"The truth is they didn't rely on themselves entirely to reach where they are. That's too difficult and the chances aren't high," Su Muyin said suddenly.

"How did they do it then?"

Su Muyin answered, "The Demon Immortal Realm is huge with lots of mysterious lands and forbidden grounds. There are also lots of areas that have been ripped by the void chasm. In these places, corpses of demon emperors might be found from time to time. It was said that those demon emperors had died for a very long time and the corpses were just chunks of their body. Nonetheless, the flesh is fresh and had energy more robust than a living creature. The corpses of demon emperors are the ultimate treasures of the Demon Immortal Realm currently. You could say that all the strongest demon kings of today have eaten the corpses of demon emperors before to reach where they are today."

"Corpses of demon emperors?"

Wu Yu was stumped once again.

He had witnessed the corpse puppet of the whale and pangolin. Their flesh was unusally fresh. Although they weren't demon emperprs, they were useful to Wu Yu to some extent.

Ordinary demon immortals couldn't devour and yet they could and become stronger by consuming the chunks of corpses left behind by demon emperors. This only suggested that the corpses of demon emperors were the scarce treasures of the Demon Immortal Realm.

After all, one wouldn't find the corpse of immortal emperor in the sky palaces or corpse of a devil emperors in hell.

Considering so many eternal demon emperors had fallen in this place, finding some chunks of corpses in a corner or forbidden ground was still natural.

And for them to keep the vitality and essences preserved until today, this was clear proof that things were different once one achieved eternal life. Moreover, eternal demon emperors were stronger in the aspect of physical flesh than immortals.

Initially, Wu Yu found the Demon Immortal Realm meaningless. All he wanted was to find Jiu Ying and to see if he was in danger.

Now that he heard the rumors of the corpse of demon emperors, he felt like remaining here. After all, if he could get his hands on them, he would definitely utilise the corpses better than others.

"When was the last time a corpse of an demon emperor was found?"

Su Muyin thought for a while before answering, "I could only remember one occasion when there was a commotion. It was 20,000 years after I've arrived. A palm was found and no one know which demon immortal it was. There was a bloodbath between demon kings and losses were severe. Many demon kings died in the battle. In the end, the strongest few distributed it among themselves before the commotion was settled. Those who got a piece got stronger substantially since then."

That was 40,000 years ago. Finding a corpse of a demon emperor wasn't easy as they were scarce and rare.

Wu Yu followed up on some details until he had a brief understanding. It was then he wanted to leave to ask around for information on Jiu Ying. He also wanted to verify his information with others.

"Don't disclose our whereabouts or we would be back for you. Here are some gifts for you." It's inevitable that Su Muyin would keep this a secret for them after Wu Yu showed kindness and threats to her at the same time.

"Don't run around~ If there's a chance, big brother could bring you around for a few rounds of fun." Full Moon of Nanshan didn't forget to tease her before they left.

After they left the place, Wu Yu wasn't completely convinced. He found several other demon immortals with one that had been around for over 30,000 years. He knew more than Su Muyin but it was clear Su Muyin wasn't lying. What she said about the Demon Immortal Realm were all true. A realm of living creatures were killed.

"How terrifying."

The truth left the trio feeling uneasy for a long time.

"What kind of catastrophic event had happened......" Ye Xixi also furrowed her brows and was shaking. She felt fortunate she wasn't born during that time.

Just imagined a demon going though hardships to ascend to immortalhood just to see corpses scattered around oneself......

"Let's see if we can find Jiu Ying first."
