Wu Yu was the first to enter the Eternal Emperor Tomb.

Wu Jun followed closely beside him. The five demonic emperors trailed along some distance away from them.

"Is this... ... glass?"

Wu Yu could feel solid ground beneath his feet. When he looked down, he realised that he was walking on a gigantic piece of transparent glass.

This piece of glass stretched out endlessly, into somewhere far away. Wu Yu could not see the end to the glass but through the glass, he could see that there was an enormous world beneath the glass.

Graves covered that world. These graves were arranged neatly in lines and the line did not seem to end. Far away, these graves were shrouded in mist. Wu Yu did not know what the mist hid.

It would be shocking if there were more graves.

As Wu Yu looked across the world, he could see the words etched on the graves. Different graves carried different words: Grave of Lifeless Eternal Demon Emperor, Grave of Grand Primitive Eternal Demon Emperor, Grave of Moon Devouring Eternal Demon Emperor, and others.

There was no doubt that these were graves of eternal demon emperors. There were actually countless eternal demon emperors buried here!

Wu Yu was amazed by the scene before him. Through the glass floor, his eyes trailed into the edges of the world. There were obviously more eternal demon emperors' graves hidden in the thick mist. He estimated that there were millions of such graves in this world.

Most importantly, the mist was too far away and no one could tell where it led to. There was also no indication of how vast this graveyard was and how many eternal demon emperors were laid to rest here.

If this place could be described to be a sea of eternal demon emperors' graves, the place that he had seen in the Apocalyptic Chaos Demon's head previously was simply a tiny pool.

"Were these eternal demon emperors destroyed during the grand battle that year?" Wu Jun was shocked too and could not resist asking.

Now they only knew that there was a devastating battle that destroyed the entire Demon Immortal Realm. In the Demon Immortal Realm, one could occasionally find some eternal demon emperor corpse. As for most of the other eternal demon emperor corpses, everyone had thought that they were utterly destroyed during the grand battle.

From what they could see now, most of the eternal demon emperors seemed to be buried in this Eternal Emperor Tomb.

"Who built this tomb?" Wu Yu was curious. He was speechless at the scale of this tomb.

He could see through the glass floor that every single eternal demon emperor grave seemed to be well preserved. Obviously, there had been no visitors. This was a highly secretive place in the Demon Immortal Realm and it also hid the greatest secret related to the devasting battle that destroyed the Demon Immortal Realm.

Perhaps, the answers to all the mysteries could be found in this Eternal Emperor Tomb. However, Wu Yu knew that danger awaited them in every corner of this Eternal Emperor Tomb.

The eight words on the bronze gates that led to the Eternal Emperor Tomb were already seeped with extremely dangerous aura, not to mention the interiors of the Eternal Emperor Tomb. Currently, they have not truly stepped into the Eternal Emperor Tomb. They were separated from the Eternal Emperor Tomb by the transparent glass floor.

Hence, at the moment they were safe.

Wu Yu and Wu Jun had not scrutinised the graves below yet. Hence, they still did not know how to break through the transparent glass floor. At this point, the five demonic emperors who had followed them into the Eternal Emperor Tomb surrounded them.

"The two of you cannot run now."

The five demonic emperors surrounded Wu Yu and Wu Jun. They have transformed into their true form and were emanating a dominant aura.

Perpetual Demonic Emperor spoke first. His voice was calm yet sarcastic. The current situation benefitted the five demonic emperors. As long as they killed both Wu Yu and Wu Jun, they could split the riches of this Eternal Emperor Tomb among themselves.

"There are too many eternal demon emperor corpses buried in the graves below and any one of them can let us breakthrough into the eternal demon immortality realm!"

Dignified Lava Beast was anxious and wanted to quickly kill Wu Yu and Wu Jun. He could not wait to go to the graves and devour those eternal demon emperor corpses.

The five demonic emperors attacked hastily with all sorts of heavenly rules after surrounding Wu Yu and Wu Jun.

However, Wu Yu had expected this and reacted quickly. When the five demonic emperors surrounded them, he brought Wu Jun into the Floating Dreams Pagoda and with a somersault, he escaped using the Somersault Cloud.

After Wu Yu left using the Somersault Cloud, he realised he was still standing on the glass floor. Similarly, he still could not see the end of the glass floor. No one knew how vast this place was.

Wu Jun came out to move with Wu Yu. They had to find a way to break through the glass floor.

"I don't think that this glass will break just because we hit it violently? It looks too sturdy. Perhaps, it has got to do with the two tiny bronze gates." Wu Jun guessed.

Wu Yu nodded. He thought so too.

The glass beneath his feet felt unbelievably sturdy. Thinking back, there was not even a scratch when the five great demonic emperors attacked the bronze gates that led to this Eternal Emperor Tomb. The things inside the Eternal Emperor Tomb would not be fragile too.

Hence, Wu Yu turned his attention to the keys, the tiny bronze gates. However, these two keys were inanimate ever since they had entered the Eternal Emperor Tomb. They no longer vibrated vigorously like before.

Just as they were studying the keys, they heard explosive sounds from far away. The sounds seemed to have come from the position of the five great demonic emperors.

Wu Yu quickly looked in that direction. He saw that the glass there seemed to have cracked under the fierce attacks of the five great demonic emperors.

It was unexpected that the glass actually cracked!

While they were far from each other, the five great demonic emperors were really creating too much noise. Wu Yu's sight allowed him to see what they have done. He could even hear the excited roars from the demonic emperors.

"Even if we can't get the bronze pendant, we can actually break this glass. As long as we can reach the eternal demon emperors' graves, we wouldn't need the bronze pendant!" Dignified Lava Beast roared jubilantly.

"That's right, we can break this glass and reach the graves directly. The two immortals are useless to us." Olden Golden Mountain spoke in a crisp voice.

They were now drunk on elation.

In the Demon Immortal Realm, even one eternal demon emperor corpse was enough to capture all their attention and even motivate them to fight for it with their lives. Now countless eternal demon emperor corpses lay buried right before them!

However, the five demonic emperors knew how dangerous this place would be and did not split up.

They might not have hoped for anything in the beginning and simply bombarded the glass floor together. It was a surprise to them as well that they managed to crack it.

They continued to attack and the entire piece of glass started to shatter from the crack.

The five demonic emperors could no longer resist the temptation and rushed towards the graves below. They were in their true forms. Each and every one of them was large enough to cover the sky, yet the graves below were equally huge. Every grave actually occupied a space that was ten times the size of their true forms.

Soon, the five great demonic emperors disappeared into the thick mist.

"Let's go down too." Wu Jun told Wu Yu.

Wu Jun, like the five great demonic emperors, was at the 9th tier of the Great Void Immortal Realm. When the opportunity arrived, he could breakthrough to the eternal immortality realm. Hence, this was the time to fight with his life.

"Yes, let's go!" Wu Yu did not hesitate. Even if there were five demonic emperors below, he could escape unscathed with the somersault cloud. He had the means to compete with them.

Hence, he and Wu Jun followed closely behind the five demonic emperors and rushed down from the crack in the glass.

Soon, Wu Yu also entered the mist. Before that, he could still see some graves clearly, but now he could not see any in the mist. All the graves of eternal demon emperors had disappeared from his sight.

Wu Yu and Wu Jun were standing so close to the graves and yet they cannot see them clearly.

"This mist is a little strange. Be careful." Wu Jun reminded with a grim expression.

The five demon emperors were now long gone. Wu Yu and Wu Jun did not know where they were now and what happened to them.

Wu Yu and Wu Jun continued to travel towards the direction of the eternal demon emperors’ graves that they had seen previously. However, no matter how long or how far they travelled, they were still in the mist and could not find any traces of the eternal demon emperors’ graves.

There were no other sounds coming from their surroundings. The white mist filled up the entire space. It was as if Wu Yu and Wu Jun were the only two persons left in this world.

"As I thought, it's not going to be easy."

Wu Yu was now very cautious and constantly alert about his surroundings.

All of a sudden, he felt as if his vision was blurred. Originally, Wu Jun was on his right, and in an instant there was another Wu Jun on his left. This happened quietly. In the blink of an eye, there were two Wu Juns beside Wu Yu.

Wu Yu was on guard immediately. The dangers of the Eternal Emperor Tomb were imminent!

When the two Wu Juns suddenly appeared, they noticed each other at the first instant and started to glare at each other.

"Wu Yu, be careful. He is a fake!"

The Wu Jun who was on Wu Yu’s right was the first to warn Wu Yu with a dark expression.

"Wu Yu, don't be fooled by him, he is the fake one!"

The other Wu Jun snapped. He looked very shocked, as if he was in disbelief as to why there was another him in this place.

"You're sprouting nonsense, he's fake. Wu Yu, let’s kill him together!"

"Rubbish. I'm the real one. Wu Yu, don't be tricked!"

The two Wu Juns started arguing with each other.

Their words, actions and expressions were all so real and skilfully imitated. From their behaviour alone, Wu Yu was not able to tell the fake from the original.

If they had appeared alone in front of Wu Yu, he would not be able to tell that the other party was a fake one. However there were two Wu Juns standing in front of him now. This meant that one of them must be a fake!

"Eyes of Fire and Gold!"

Wu Yu instantly used his mystique, Eyes of Fire and Gold. A golden light shot out from his eyes.

His Eyes of Fire and Gold first shone on the two Wu Juns. Very quickly, he saw that one of the Wu Jun's true form was the mist and not a Primordial Immortal Dragon. He immediately knew that that Wu Jun was fake.

"Attack!"

Wu Yu did not hesitate and with a sweep of his arms, he attacked the fake Wu Jun. Void Reversal followed by the Submerged Cloud Seal landed explosively with terrifying power on the fake Wu Jun!
