The real Wu Jun did not simply stand around. His Dragon Breath heavenly rule shot through the mist onto the fake Wu Jun.

Under the double whammy, the fake Wu Jun cackled sinisterly and transformed into mist, dissolving into the surrounding mist. Both Wu Yu and Wu Jun's attacks landed on nothing.

Their fierce attacks clashed and exploded, causing a strong wind to billow out. The mist was slightly dispersed but they gathered again quickly, once again obscuring Wu Yu and Wu Jun's sight.

When they looked up, they could see nothing but a whole stretch of white mist. They could not see anything else.

Wu Yu had no choice but to continue walking forward. Wu Yu and Wu Jun had just advanced a few steps when Wu Yu realised that Wu Jun seemed to have disappeared. He was covered by mist and seemed to have turned invisible, hidden into the surrounding mist, just like the fake Wu Jun.

Wu Yu was shocked. Now he was all alone.

He walked one round and could not find any trace of Wu Jun. Hence, he could only use an immortal message talisman in attempt to contact Wu Jun.

Soon, he realised that even immortal message talismans were useless here. It was as though Wu Jun had entirely disappeared from this world. This was an eerie experience.

"This is too strange."

Wu Yu frowned. While he could not find Wu Jun, it was no solution to simply stop and wait. He had to move on alone.

This mist was endless and when Wu Yu was alone, the whole place seemed even quieter. He felt as though he was the lone survivor in the entire world. He now had to maintain his Eyes of Fire and Gold at all times.

This was to prevent him from failing to identify any more fakes that might appear beside him.

Wu Yu was already cautious due to the incident of the two Wu Juns. It was highly likely that this mist could affect one's senses and mind. Hence, only the Eyes of Fire and Gold could mitigate this effect.

Suddenly, there was noise coming from ahead of him. Then Wu Yu sensed that the surrounding seemed to have heated up. He moved forward cautiously and finally saw someone familiar. It was the Dignified Demonic Emperor, the Dignified Lava Beast!

That Dignified Lava Beast's true form was a formless mass of lava with a mouth. He seemed to have detected Wu Yu's arrival at the same time Wu Yu sensed him. He grinned evilly: "I didn't expect for you to show up voluntarily!"

Obviously, this Dignified Demonic Emperor was still thinking of that two tiny bronze gate pendant that Wu Yu had. That was the key to opening this Eternal Emperor Tomb. It might have other uses inside the Eternal Emperor Tomb.

Hence, he wanted to snatch the two tiny bronze gate pendant!

Wu Yu of course would not allow him to do that. It looked like the five demonic emperors had been split up upon entering the mist. It was the same as what had happened with him and Wu Jun. Since the Dignified Demonic Emperor was alone now, Wu Yu had no need to retreat.

"Fight!"

Wu Yu decided that this was the opportunity for him to test his improved strength. He had only had a friendly match with Wu Jun and did not know the limits of his true strength in a battle yet.

Even at this point, Wu Yu still used his Eyes of Fire and Gold to look at the other party's true form and confirmed that it was indeed a Dignified Lava Beast. He believed that this must be the real Dignified Lava Beast and not an illusion conjured up by the mist.

Whereas, the Dignified Lava Beast attacked first.

"Melting Explosion Heavenly Rule!"

The Dignified Demonic Emperor roared and that Dignified Lava Beast's huge mouth widened. A fiery ball of lava that could burn the entire space erupted. In an instant, it reached Wu Yu and exploded.

With the onslaught of the Melting Explosion Heavenly Rule, the temperature around Wu Yu rose sharply. It seemed like he was immersed in the middle of a lava stove. His hair curled up quickly and even looked like it was about to burn!

The ability and strength of a 9-heavens demon king was really incredible and must not be underestimated.

Moreover, the other party's Melting Explosion Heavenly Rule landed on Wu Yu too quickly. It exploded instantly in front of Wu Yu, leaving him nowhere to hide. He could only use the Void Reversal on reflex. The Qian Kun world and void world reversed immediately, pushing away the other party's Melting Explosion Heavenly Rule!

However, even with the Void Reversal, Wu Yu had only barely managed to defend himself. If he reacted any slower, the Melting Explosion Heavenly Rule would definitely injure him.

Now both Wu Yu and the Dignified Lava Beast were in the void world, but even this condensed void world was filled with mist. Wu Yu could not see anything far away.

The other party's Melting Explosion Heavenly Rule was reversed and exploded in the outside world. The terrifying high temperature did not affect Wu Yu at all in the void world.

The Dignified Lava Beast was miffed. The lava on his entire body started to boil furiously. A black and red flame rose from the sides of his huge lava body: "Hellish Fire Heavenly Rule!"

That black and red flame looked like it emerged from hell. It cloaked the Dignified Lava Beast and made his aura become increasingly domineering. Soon, the Hellish Fire Heavenly Rule was burning all over his body, increasing his combat power by multiple folds.

This was similar to Wu Yu's santified flesh heavenly rule or the crusader heavenly rule. Once used, he could enhance his strength by leaps and bounds.

However, it was obvious that the Hellish Fire Heavenly Rule was not easy to use. The Dignified Lava Beast had spent a lot of effort and time to use this heavenly rule and yet he still had not managed to exhibit the full power of the Hellish Fire Heavenly Rule.

Wu Yu immediately took action. He knew that once the other party's Hellish Fire Heavenly Rule really took form, it was likely that the Dignified Lava Beast could kill him with just that one move.

"Violent Art!"

"Submerged Cloud Seal!"

Wu Yu transformed into a huge golden ape in an instant. The crusader heavenly rule and santified flesh heavenly rule had already been activated, boosting his entire body. He attacked explosively as his strength increased exponentially with the Violent Art.

The Dignified Lava Beast was now in the void world. In an instant, the Submerged Cloud Seal landed on him and exploded. The destructive power of Wu Yu's Submerged Cloud Seal was stronger in the void world. It burst out in an explosion, breaking through and shattering the Dignified Lava Beast's Hellish Fire Heavenly Rule!

But it was not that easy to completely break the other party's Hellish Fire Heavenly Rule.

A part of the black and red flames remained, covering the Dignified Demonic Emperor's huge lava body. His strength was still increased to a certain extent.

After being destroyed by Wu Yu's Submerged Cloud Seal, the Hellish Fire Heavenly Rule covering the Dignified Demonic Emperor was already not in the complete state. However, the Submerged Cloud Seal did not hurt the Dignified Demonic Emperor at all. Now, with the addition of the Hellish Fire Heavenly Rule, the Dignified Demonic Emperor continued to attack Wu Yu.

The dominance of a 9-heavens demon king flowed out like a towering wave: "Casting Heavenly Rule!"

A brilliant pillar of flames shot down from above. This Casting Heavenly Rule transformed into a pillar of fierce flames rushing towards Wu Yu. This pillar turned everything on the way into ashes. The extreme heat was enough to melt Wu Yu on the spot.

The unique part of the Casting Heavenly Rule was that it contained a part of the black and red flames. That was the form that the Dignified Demonic Emperor took when he was covered with the Hellish Fire Heavenly Rule. The power of the Casting Heavenly Rule was amplified under the Hellish Fire Heavenly Rule.

Wu Yu did not dare to make any mistake and instantly split into millions of doppelgangers. Every doppelganger was in the form of a golden ape. At this moment, Wu Yu used his doppelganger heavenly rule.

A million doppelgangers attacked at the same time. The doppelganger heavenly rule condensed into a sky shaking earth breaking ray of light, clashing right into the other party's casting heavenly rule pillar of flames!

Both powers exploded upon contact in the mist of the void and almost dispersed all surrounding mist.

The pillar of flames from the casting heavenly rule and Wu Yu's doppelganger heavenly rule was evenly matched. They clashed violently but none could claim victory. It was actually a tie.

Wu Yu had many moves now but the doppelganger heavenly rule was already one of his stronger moves. This showed how strong the Dignified Lava Beast was. Wu Yu would have a hard time disposing of the other party.

However, he did not give up.

The other party seemed to have entered a cooldown period after this move. Wu Yu used this opportunity to attack. The heavenly rule power in his body continued generating power. Most importantly, Wu Yu used his Lawful Embodiment of Heaven and Earth to turn into a giant.

Wu Yu's current power was much stronger than previously. Both of his eyes glowed with gold light in the mist.

"Golden eyes heavenly rule!"

Wu Yu's golden eyes became the brightest existence in this foggy mist. The golden light shone through layers of mist and smashed onto the lava body of the Dignified Demonic Emperor.

"Rock Shield Heavenly Rule!"

Dignified Demonic Emperor's body seemed to be cloaked with a layer of thick rocks, enveloping him like an armour. He took on Wu Yu's golden eyes heavenly rule attack directly. This was the only move that he could use within this short period of time.

It was a pity that Wu Yu's golden eyes heavenly rule was boosted by all sorts of buffs. His santified flesh heavenly rule, crusader heavenly rule, violent art, and Lawful Embodiment of Heaven and Earth were all buffering the attack of the golden eyes heavenly rule. This allowed the golden eyes heavenly rule to be powerful enough to penetrate through almost anything.

In the next instant, the armour formed by the power of the Rock Shield Heavenly Rule was pierced through by the golden eyes heavenly rule. That golden light had easily pierced through Dignified Demonic Emperor's defenses, dispersed his Hellish Fire Heavenly Rule and shot into his lava body.

Dignified Demonic Emperor roared in rage, his roar tinged with pain. Obviously, he was heavily injured by Wu Yu's golden eyes heavenly rule.

"Well, you're good!"

The Dignified Demonic Emperor growled and quickly turned to run.

Wu Yu now had the upper hand in battle and would not allow his enemy to simply escape. However, the other party had entirely disappeared even though he entered the mist for only a second.

It would be like looking for a needle in a haystack to find the Dignified Demonic Emperor in this heavy mist. Wu Yu frowned.

It was not easy to injure the Dignified Demonic Emperor. He had not expected for the Dignified Demonic Emperor to immediately run away. If he could kill him, then he would have gotten rid of a potential risk.

It was a pity that the Dignified Demonic Emperor managed to escape. Wu Yu could only advance again through the heavy mist.

Soon, battle sounds came from ahead again and this battle seemed to be even more violent than his battle with the Dignified Demonic Emperor.
