Xiao Ning and the Demon Emperor tried to look at each other a few times, which made the faces of both sides become solemn.

Of course, there is no victory or defeat in the temptation, there is only an understanding of each other's strength.

Xiao Ning has always suspected the existence of the Demon Emperor in the Demon Domain, and today he finally encountered it. It's just that I didn't expect that the strength of this demon emperor would be so strong.

Originally, Xiao Ning thought that even if there was a Demon Emperor in the Demon Domain, its strength should be about the same as that of the Ghost Emperor Yan and the Hell Refining Fire Emperor, at most it was at the level of the Blood Demon Emperor. However, this temptation surprised him greatly, this Demon Emperor's strength was not only far superior to that of the Ghost Emperor Yan and the Hell Refining Fire Emperor, but even compared to the Blood Demon Emperor, it was also a step stronger.

Of course, this was not Xiao Ning's subjective conjecture, he had fought with the Blood Demon Emperor, and he had also fought with the Hell Refining Fire Emperor. Although he didn't have too much contact with the Ghost Emperor Yan, the Hell Fire Refining Emperor was able to compete with the Ghost Emperor Yan in the Ghost Domain, and presumably the strength of the two sides should be at the same level.

Compared with Xiao Ning's surprise, the Demon Emperor was also surprised. The reason why he hasn't shown up is not because he doesn't want to show up, but because he has been sealed in the Demon Slaying Tower of the Demon Domain.

If Xiao Ning was born in the Demon Domain, he would definitely know. I don't know when a demon tower appeared in the demon domain, and all the masters of the demon domain can't get close, even the demon king.

In fact, this Demon Emperor has been in the Demon Domain for a very long time, so long as it is earlier than the appearance of the Ghost Emperor Yan and the Hell Fire Refining Emperor.

As soon as he was born, he brought a bloody storm to the demon realm.

The Demon Emperor was not born by conception, but was born from the heavenly thunder. At that time, there was a thunderclap in the sky of the Demon Domain, and then a thunderball descended on the Emperor, and a teenager walked out of the thunderball. The young man looked very weak, with a touch of bewitching on his body, with a positive Taiji diagram on his chest and an anti Taiji diagram on his back. If it weren't for a long tail and pointed ears, he would have been mistaken for a human, but he is indeed a demon, and a demon with great strength.

In the first year after coming out of the thunderball, the strength of the Demon Emperor who fell from the sky reached the level of the Demon Emperor. Don't look at you, he is polite on the surface, but he acts very decisively. After cultivating to the level of the demon king, in just one year, he unified the demon domain, and all the demon kings of the original demon domain were willing to become his courtiers. After another period of time, the Demon Emperor who fell from the sky finally reached the emperor level and began to plan to invade the Xiuzhen world.

That time the Demon Emperor had basically succeeded, but it was a pity that several true immortal clones appeared in humans later, and the artifact of the Demon Suppression Tower was also left at that time. However, this Demon Town Tower was not brought down by the True Immortal Clone, but when the Demon Emperor was about to return to the Demon Domain to regroup, the Demon Town Tower suddenly came and suppressed it in it.

Now it seems that although the Demon Emperor Evil was successfully suppressed by the Demon Emperor Tower, it was not able to stop him from continuing to grow stronger, and now the strength of the Demon Emperor is much stronger than at the beginning.

However, even so, after a temptation with Xiao Ning today, he still failed to successfully suppress the other party, and the two sides were evenly matched.

Swish......

The figure of the Demon Emperor moved again, turning into a demonic figure and attacking Xiao Ning.

The temptation phase has passed, and this time the Demon Emperor is going to launch a real attack. The spear in his hand "pierced the sky" was dazzling, and the little guns converged into a huge gun shadow, stabbing directly towards Xiao Ning.

Xiao Ning did not show weakness, and waved the divine sword in his hand, turning into a huge wave of swords, and greeted the Demon Emperor.

Rumble......

When the huge wave met the shadow of the gun, there was a loud bang in an instant, and a powerful shock wave spread in all directions.

The spear "piercing the sky" is arrogant and uninhibited, not afraid of the power of heaven, which shows its bravery; the divine sword does not confuse the possession of dual spirits, and does not sleep in life and death, which shows its wisdom. Therefore, this collision between Xiao Ning and the Demon Emperor is more like a collision of wisdom and bravery.

Whew......

Xiao Ning's figure retreated instantly, the impact was too strong, and he could only retreat to resolve it. After standing firm, Xiao Ning's face became more solemn, and he looked a little pale because of the previous collision, and now he was nearly twenty zhang away from the place where he collided before.

It was also impossible for the Demon Emperor to stay where he was, and under the powerful backlash, his figure also retreated sharply, and his slightly demonic face also looked a little pale.

After the blow, the two sides fell silent again, as if nothing had happened, but whether it was the Demon Emperor or Xiao Ning, their expressions became extremely solemn.

Of course, both Xiao Ning and the Demon Emperor were very shocked in their hearts at this time. The shock came from two aspects, one was the strength of the opponent, and the other was the solidity of this Xuanwu Palace.

With the aftermath of the collision between Xiao Ning and the Demon Emperor, even the mountains would be shaken three times, but this Xuanwu Hall did not move at all.

Of course, this is not the main thing, the main thing is that they have such a powerful attack, they can't shake the Xuanwu Palace, so most of the inside of this Xuanwu Point building has been destroyed, who did this? How strong is it to be able to destroy this place to this extent.

"You're good!"

When Xiao Ning was about to fight the Demon Emperor again, the Demon Emperor suddenly spoke.

"What do you want to say?"

Xiao Ning frowned, the arrival of the Demon Emperor had puzzled him all the time, why did he come, why did he arrive when he appeared? This is too much of a coincidence.

"I'm here to work with you!"

The Demon Emperor's answer was very calm, but Xiao Ning's eyes widened, and he didn't know what this Demon Emperor wanted to do.

After a long time, Xiao Ning spoke: "What do you want to cooperate with me?"

Xiao Ning really didn't know what the Demon Emperor wanted to do, and he didn't know what cooperation the Demon Domain Emperor would talk about with him.

"What would you do if I said that I asked you to cooperate with you to deal with the Blood Demon Emperor?"

The Demon Emperor spoke slowly, in fact, he was also a little worried in his heart.

"Blood Demon Emperor, why?"

Xiao Ning didn't know why the Demon Emperor wanted to deal with the Blood Demon Emperor, and he still had to find himself. Is it because of personal grudges, or because the Demon Emperor also knows about the things between the big worlds.

"I'm dealing with the Blood Demon Emperor because it's my responsibility, but I think you're also responsible!"

The Demon Emperor spoke again, if he let others hear it, he would already feel inexplicable, but Xiao Ning didn't think so.

"Looks like you know about the war there!"

Xiao Ning's brows furrowed slightly, he was not sure whether he should believe in the Demon Emperor or not, but if he compared it with the Blood Demon Emperor, he would prefer to believe in the Demon Emperor.

"I know, I knew it when I was born, this is the only thing I know in my heart!" Demon Emperor's voice was a little firm, but Xiao Ning heard a hint of something strange from it.
