Wu Yu and Wu Jun were just a short distance from the bronze gates or the entrance to the Eternal Emperor Tomb. They had kept themselves hidden.

They could sense the shockwaves from the five demonic emperors blasting the bronze gates. However, from the information that Full Moon of Nanshan had sent back, the attacks from the five demonic emperors seemed to be futile.

However, Full Moon of Nanshan came back with another piece of information shortly. "Old Wu, there's a little dent in the center of the two huge bronze gates. I believe your pendants should fit in it. Could that be the way to open these gates?"

Wu Yu pondered and replied, "Continue observing the situation. With the five demonic emperors around, I can't just try something so risky and expect to come out ahead."

Full Moon of Nanshan was also aware that it wouldn't be practical for Wu Yu to head over. He continued to observe and found the five demonic emperors seemed to be fixated on the bronze gates that exceeded all other matters in the Demon Immortal Realm.

In fact, the five demonic emperors started putting up immortal designs in all directions of the bronze gates. Those dreadful and potent elite great void immortal designs were for preventing others from approaching while also empowering them with greater strength to open up the Eternal Emperor Tomb.

Full Moon of Nanshan had to get further and further away as the demonic emperors constantly extended the coverage of the immortal designs outwards. Soon, formidable immortal designs surrounded the Eternal Emperor Tomb.

Although Full Moon of Nanshan couldn't get closer, he still could see the situation at the bronze gates from where he was.

The five demonic emperors were still attempting a myriad of ways to blast the bronze gates. Unfortunately, the bronze gates didn't budge an inch at all.

Wu Yu was also discussing with Wu Jun.

"Would this be a tomb where the eternal demon emperors were buried? If this is the case, how frightful would the one who created the Eternal Emperor Tomb to bury all those eternal demon emperors be?" Wu Jun sighed.

When he was in the sky palaces and Primordial Immortal Empire, he had seen many eternal immortal emperors. However, even those eternal immortal emperors wouldn't be capable of forging the Eternal Emperor Tomb. The fact that the bronze gates weren't budging an inch despite bombarded by attacks from five 9-heavens demon kings was clear indication of the issue.

Over the next few hundred years, the five demonic emperors had put up various offensive great void immortal designs that could also enhance their personal strength to the limits.

With these one-off offensive great void immortal designs and with their strength all released explosively, this was comparable to an attack from an eternal immortal emperor. Even so, the bronze gates didn't move an inch.

Since the bronze gates appeared until several hundreds years later, they remained in the air. No matter how the demonic emperors bombarded it, the gates didn't move from their intial positions or show any signs of being destroyed.

It was as though the gates were the toughest things in this world and the five demonic emperors had ran out of options.

Finally, two thousand years had passed. The five demonic emperors even called upon their 8-heavens demon king subordinates to help. With their combined attacks, their destructiveness multiplied several times. Yet, they were unable to even move the bronze gates the slighest.

Elite demon kings across the Demon Immortal Realm had gathered around the bronze gates but none was successful in any way.

Finally, the five demonic emperors gathered together on one day. Unending Demonic Emperor recalled the incident with Wu Yu and Wu Jun and had a brainwave.

Previously, they wanted to open up the bronze gates by themselves and enter into the Eternal Emperor Tomb. However, they now knew this wouldn't be plausible. Therefore, they had to look elsewhere. The five demonic emperors wracked their brains and Wu Yu seemed to be the only hope.

After all, Wu Yu was loitering in the vicinity previously. If it wasn't so, they wouldn't have found the Eternal Emperor Tomb. There's a good chance that Wu Yu would have a way to open the bronze gates!

Therefore, they started sending news out, indicating they would want to cooperate with Wu Yu. The news quickly spread through the Demon Immortal Realm so Wu Yu could be informed about it.

The truth was Wu Yu wasn't far away. Obviously, he had concealed himself so the demonic emperors wouldn't find him.

He heard about the intention of the other party to cooperate.

Over the past two thousand years, Wu Yu wasn't just waiting for nothing.

Initially, he wanted to wait till the five demonic emperors retreat from the place before giving a try to open the bronze gates. However, the five demonic emperors clearly wouldn't give up on this location. Therefore, Wu Yu had no other opportunity.

Moving ahead, the five demonic emperors might even coop up in this place for several hundreds of thousands of years to research further. Wu Yu couldn't just wait forever. It wouldn't be sensible for him to assume he could outlast the demonic emperors in patience.

Therefore, Wu Yu had focused on his own cultivation during this period.

In fact, after receiving news that the five demonic emperors were interested in cooperating, Wu Yu didn't stop. Instead, he continued cultivating. The dao enlightenment he had received after devouring the Apocalyptic Chaos Demon had not been fully digested. He had been taking it slow in delving into the dao enlightenment.

Now that he was focused on cultivating and increasing his cultivation realm, Wu Yu reaped considerable rewards.

He was currently in the critical stage of cultivating and therefore couldn't just step forward to cooperate with the demonic emperors. At the very least, he wanted to at least have the strength to battle a 9-heavens demon king.

After all, without the mini bronze gate pendants he was holding, the five demonic emperors wouldn't be able to enter the Eternal Emperor Tomb. He could just focus on his cultivation!

In the two thousand years, he started with enhancing his Mystique, Eyes of Fire and Gold. After a long time of consolidation, the Eyes of Fire and Gold had reached a new level known as Golden Blazing Realm. With his eyes, he could set his opponent ablaze with Golden Blazing Realm Fire.

The appearance of the Golden Blazing Realm allowed Wu Yu to delve deeper into new techniques and form his new heavenly rule.

Therefore, he didn't respond to the the news of the five demonic emperors wanting to cooperate with him, continued his cultivation and completed creating his fifth heavenly rule. This was a heavenly rule that was built upon the new realm of Eyes of Fire and Gold, the golden eyes heavenly rule!

If he only had the Golden Blazing Realm Fire, it would still be difficult to defeat his opponent. However, after forming his fifth heavenly rule, it would be different. The golden eyes heavenly rule was at the level of the combination of Void Reversal with Submerged Cloud Seal.

In fact, its destructiveness would become one of the strongest means that Wu Yu possessed after Violent Art, Lawful Embodiment of Heaven and Earth, crusader heavenly rule and sanctified flesh heavenly rule.

Since he stepped into the Great Void Immortal Realm, heavenly rule power had been the main battle techniques of an immortal.

It was the same for Wu Yu. Void Reversal together with Submerged Cloud Seal would be one of his strongest technique. However, there were two other that were stronger. One of them was having his 1 million doppelgangers casting doppelganger heavenly rule at the same time and the other was the golden eyes heavenly rule.

To put it simply, these two heavenly rule power wouldn't require a combination. It would be easier and more explosive when using and was more convenient thatn Void Reversal with Submerged Cloud Seal.

Initially, he was cultivating next to Wu Jun. Now, they entered the Floating Dreams Pagoda and Wu Yu informed Full Moon of Nanshan to continue observing the demonic emperors.

This remained the same until 30,000 years had passed. He finally completed his cultivation and formed his fifth heavenly rule. After becoming a 5-heavens immortal king, he raised his tier of Lawful Embodiment of Heaven and Earth to a new level too.

With Lawful Embodiment of Heaven and Earth, he could now unleash strength that was one fold greater than before. The results of 30,000 years of cultivation were stark and lifted his overall battle strength to a new level.

"I should be able to handle a 9-heavens immortal king now. Although I can't defeat one, the other party wouldn't be able to take me down too!" Wu Yu now had this belief.

30,000 years had passed and nothing much had changed for the five demonic emperors or the Demon Immortal Realm. They were still looking for Wu Yu while also trying to uncover the mysteries of the bronze gates.

Wu Yu wasn't in a hurry. He remained in the Floating Dreams Pagoda while asking Full Moon of Nanshan to carry it around. No one could possibly locate them.

In fact, there were also rumors saying Wu Yu's group had long left Demon Immortal Realm. It was just that before the five demonic emperors could verify the authencity, they weren't willing to give up searching.

Within the Floating Dreams Pagoda, Wu Yu tried sparring with Wu Jun as a test of his current strength.

"Wu Yu, be careful! I wouldn't hold back," commented Wu Jun solemnly.

Since they would be sparring, he would want to see the level of strength that Wu Yu could reach currently. He believed Wu Yu wasn't wasting time over the last 30,000 years.

Previously at the depths of the void chasms, he had witnessed Wu Yu's strength in battle. He knew Wu Yu could kill a 8-heavens demon king and wasn't too far off from a 9-heavens demon king.

Now that 30,000 years had passed, Wu Yu definitely got stronger. Wu Jun wouldn't have to worry he might kill Wu Yu if he had gone all out.

"Alright." Wu Yu nodded his head and was prepared for any eventuality.

Within the Floating Dreams Pagoda, they started sparring. Wu Jun started by gathering his immortal qi around his body to attack with Dragon Breath heavenly rule. This was the heavenly rule he used against the Fathomless Starry Sea. However, the Fathomless Starry Sea was too cunning and the attack didn't had the intended effects.

The truth was the Dragon Breath heavenly rule was one of the strongest technique that Wu Jun had. The dragon breath that encompassed immortal qi quickly surrounded Wu Yu and exerted frightful pressure.

"Void Reversal!"

As the Dragon Breath heavenly rule descended, Wu Yu cast Void Reversal. At the same instance, he unleashed Submerged Cloud Seal that was enhanced by crusader heavenly rule and Sanctified Flesh heavenly rule. The space where the Dragon Breath heavenly rule was landing collapsed and Wu Yu successfully stopped the attack!

Both parties unleashed terrifying power in the Floating Dreams Pagoda but still didn't do any damage to the Floating Dreams Pagoda.

Wu Jun was a little surprised. Although he expected Wu Yu to be capable of stopping his attack, he didn't expect Wu Yu to have done it so easily.

This piqued his interest. "Again! Ravaging Immortal Thunderbolt heavenly rule!"

Wu Jun unleashed his heavenly rule again. The Ravaging Immortal Thunderbolt heavenly rule was one that he used sparingly. The power was even greater than the Dragon Breath heavenly rule but it would render him exhausted for a brief period after casting. Therefore, he had not used this frequently.

At this very moment, terrorizing thunderbolt burst forth in the Floating Dreams Pagoda, bombarding down on Wu Yu from all directions!

"Violent Art, Lawful Embodiment of Heaven and Earth......"

"Golden eyes heavenly rule!"

Wu Yu transformed into the golden Immortal ape while casting Violent Art and Lawful Embodiment of Heaven and Earth. Under the enhancement of crusader heavenly rule and Sanctified Flesh heavenly rule, his strength was at his limits. Immediately after, brilliant light burst from his eyes and dazzled the battleground.

Ravaging Immortal Thunderbolt heavenly rule clashed with the golden eyes heavenly rule. Heavenly rule power exploded and it was clear Wu Yu wasn't at a disadvantage at all.

Even with his strongest technique, Wu Jun couldn't do a thing to Wu Yu. This was clear indication of the level of strength Wu Yu currently possessed!
