In the midst of lightning and fire, the black magic knife of the Demon Venerable suddenly appeared, and it also appeared behind Xiang Zhenxuan, and it also carried an extremely strong force.

It was too late, it was too late, Xiang Zhenxuan was keenly aware that the opponent's magic knife appeared behind him, and he quickly swung the knife to resist the opponent's magic knife.

At this time, the Duo Ming Demon Venerable appeared in front of him very suddenly, and his hands were claw-like and attacked Xiang Zhenxuan's upper and lower two vital points.

Xiang Zhenxuan shouted violently, and the moment he slashed the Demon Knife, he swung the knife and slashed towards the arms of the Demon Venerable.

The treasure knife in his hand suddenly shone brightly, and a powerful and terrifying sword suddenly burst out, forcing the Demon Venerable to retreat.

When the battle between Duo Ming Demon Venerable and Xiang Zhenxuan was extremely fierce, Du Yunfeng began to perform the "Wuzhuang Divine Seal Technique" at the same time as the clone.

Under its powerful mental calculations, each seal did not affect the others.

Soon after the first seal was re-sealed at the entrance, the second seal followed, followed by the third, and then the fourth......

Soon the eight seals were sealed at the entrance one after another, and after a while, the eight seals were sealed at the entrance one after another.

This was repeated eight times, but this time Du Yunfeng had successively arranged eight or sixty-four seals, and the seals he had designed were also added.

Coincidentally, when he finished arranging the eighty-eight and sixty-four seals, he was thinking about how to enter the world where Xiang Zhenxuan was, but the demon world sent an attack.

Du Yunfeng immediately opened the formation that had been arranged earlier, and then saw the scene at the entrance of the Demon Realm, and then saw that a demon cultivator was injured by the rebound force because of the seal that attacked him, although it was a slight injury, but Du Yunfeng was still in a good mood.

"Fortunately, my seal was arranged quickly, otherwise now there is another Demon Venerable, and this seal is absolutely useless." Du Yunfeng said secretly: "And now that my seal has been arranged, even if you are a Demon Venerable, it will be difficult to break my seal, unless you are a Demon Venerable Dual Heaven powerhouse who understands this way, or a Demon Venerable Triple Heaven powerhouse." If you are just a Demon Venerable Heavenly Cultivator, hehe, I'm afraid that you won't be able to enter even if my seal smooths out the entrance. ”

After Du Yunfeng saw that the Demon Venerable couldn't help his seal after trying several more times, his mood was even better.

And at this time, a crack suddenly appeared in the space not far from him, and Du Yunfeng's heart moved, instantly became invisible, and flashed towards the crack.

Although it was only a crack, he saw through the crack the scene inside, and he saw the two powerhouses in the middle of the battle.

Du Yunfeng immediately entered the secret realm of fighting.

And the reason why he dared to appear here at this moment was because this was Xiang Zhenxuan's main battlefield, and second, he left his clone outside to deal with the seal.

When Du Yunfeng appeared in the Fighting Secret Realm, Duo Ming Demon Venerable and Xiang Zhenxuan both noticed it, but soon only Xiang Zhenxuan could detect where Du Yunfeng was.

But in this secret realm, Xiang Zhenxuan had already relied on his own advantages to cover Du Yunfeng.

The Demon Venerable sneered, "A little bug with a hidden head and tail also wants to hurt me? What a wishful thinking! Although he said it easily, he did not relax in the slightest, and he could even be said to be more vigilant.

Suddenly, powerful swords appeared in all directions of the Demon Venerable.

The power of those swords, even as a Demon Venerable, was a little surprised.

He didn't expect that the little insect he hadn't looked up to before would be able to emit such an amazing sword light.

The magic knife in his hand suddenly spun rapidly, but one after another the sword rays successfully offset the sword rays, and they also attacked in all directions with great momentum.

Du Yunfeng secretly said: "It is worthy of the Demon Venerable, this combat power is indeed not simple!" ”

At this time, Xiang Zhenxuan's treasure knife broke out again.

"Bang bang bang!" With Xiang Zhenxuan's series of fast attacks, even the Demon Venerable of Duo Ming was not injured.

Xiang Zhenxuan sneered: "Against me, you still have the heart to make a move against other monks!" ”

Xiang Zhenxuan's madness made Duo Ming Demon Venerable very unhappy, and he said coldly: "Hugh is rampant, and it will definitely beat you to the ground in a while." ”

"Blowing nonsense has always been a fine tradition of your demon cultivators?" Xiang Zhenxuan sneered.

"Phew!" The Demon Venerable of Duo Ming showed a fierce light, and he wanted to kill the other party immediately.

However, although its mood is very bad, its combat power has not been affected in the slightest, and its performance has been stable.

As the fierce battle between Xiang Zhenxuan and Duo Ming Demon Venerable continued, Du Yunfeng intervened a few times, but he failed to achieve the desired effect.

Du Yunfeng said secretly: "Now it seems that there are only two choices, one is to break through the cultivation and reach the quasi-zun, so that my combat effectiveness will inevitably be greatly improved, and if I make another move at that time, this demon venerable will definitely die; The second is a lottery to see what useful good things can be drawn. After a little hesitation, Du Yunfeng immediately decided to break through first, after all, if there is no good result in the lottery, it still needs to break through, and if there is no good result in the lottery, it is easy to cause trouble because of the passage of time.

Of course, he also thought about breaking through and drawing at the same time, but in the dark he always felt that the results of the lottery after his breakthrough were definitely different from the lottery before the breakthrough.

In the dark, it was as if a voice was saying to him: "It's better to draw a lottery after a breakthrough." ”

It is precisely because of this that he did not choose to break through and draw at the same time.

At that moment, Du Yunfeng left a few clones to assist Xiang Zhenxuan in the Fighting Secret Realm, and his own deity left the Fighting Secret Realm.

After all, he wants to break through, but he doesn't want his breakthrough to be disturbed by external forces and something bad will happen.

In fact, with the continuous accumulation of Du Yunfeng, he has already reached the standard that can be broken through, but he has been suppressing himself and has not allowed himself to break through.

After all, breaking through early is not all good things, for example, if he encounters a quasi-venerable realm one-tier heavenly demon cultivator, if he breaks through and kills him, he won't get anything, if he doesn't break through and kill him, he will get an immortal cultivation stone, and a cultivation immortal stone represents an opportunity with infinite possibilities.

It was this mysterious opportunity that became the main reason why he didn't want to break through in a hurry.

But now the immortal cultivators in the immortal world need him to break through, and Xiang Zhenxuan needs him to break through, so he has no hesitation to break through, without a trace of unwillingness.

Even if this breakthrough would affect him to receive an unknown number of immortal cultivation stones in the future, he would have no regrets.

In his opinion at this moment, it doesn't matter what the immortal stone is, the important thing is to kill the demon venerable who is fighting with Xiang Zhenxuan for the immortals in the Xiangxiang realm.
