"Crunch—"

After staring at the closed iron door silently for a moment, Du Fei's sleeves flicked slightly, and then he saw the originally closed iron door slowly pushing open towards the rear. Seeing this scene, Du Fei took a slow breath, and did not hesitate too much, but stepped on the soles of his feet, that is, he stepped forward directly.

Behind the iron gate, there was also a long passage, which spread diagonally upward, and it was obvious that as the passage went, it would go deeper and deeper into the top of the tower. After walking slowly through the long passage for more than half an hour, Du Fei's eyes suddenly opened up, and then, a large hall that was nearly one-third smaller than before appeared in his sight. The light in this hall is a little darker than the first hall, and you can vaguely see a lot of huge stone pillars around, which makes this hall appear more and more mysterious.

At this moment, there was silence in this hall, and after Du Fei was silent for a moment, he stepped on the soles of his feet, but his figure fell to the center of the hall in an instant, and then, his gaze fell to another passage. If he guessed correctly, among the nine passages into the tower, the place where the first battle converged should be a situation of three-way chaos, and if it reaches this level, it may also be a situation of three-way chaos, and then it will be able to directly divide the winner and determine who can get the qualification to climb the tower. Of course, there is also a certain possibility that only two people will have to fight in this second round, and the winner will fight the last person to determine the place of Nadeng.

Although he didn't know which of the three situations he encountered at this moment, Du Fei's mind was not half relaxed, but after narrowing his eyes slightly for a moment, he fell into the depths of this hall again, where there was also an iron door, obviously, as long as he pushed it open, he could directly enter the next level.

However, at this moment, Du Fei did not walk over directly, but after being silent for a while, he actually put his hands behind his back, his eyes narrowed slightly, as if he was closing his eyes to recuperate.

It's just that although Du Fei is pranayama with his eyes closed at this moment, he has not slackened in the slightest, and at this moment, he is still not sure whether he will have an opponent, perhaps, he will meet two opponents. But no matter what, it's always right to be a little cautious.

After all, none of the strong people who can go to this place will be weak, and those strong people who can stand out from the three-person brawl are the pinnacle of the Kyushu battlefield.

Therefore, no matter whether it will be one person or two people who will appear in front of him in the end, the person who can come this far will definitely be a master of extreme terror.

In such a quiet wait, half an hour passed slowly, but Du Fei's brows were slightly furrowed, and his eyes fell to the deep passage on the opposite side for a moment before he slowly exhaled. In this situation, it seems that you don't need to solve any opponents, can you go to the next level smoothly?

As soon as he thought of this, even with Du Fei's heart, he slowly exhaled at this moment, and his body, which had been tense, instantly relaxed a little.

"Whoa—"

However, at the moment when Du Fei's aura loosened, behind a stone pillar behind him, a gray aura suddenly surged strangely, and then that aura trembled instantly, and it had turned into a streamer, stabbing towards Du Fei's place at an extremely terrifying speed!

The attack of this shadow was extremely terrifying and weird, without the slightest sharp wind and fluctuations, but this kind of sharp smell was so cold that it made people's scalps tingle.

This kind of offensive was obviously issued by a master who had been dormant for a long time, but the most shocking thing was that this master was able to lurk for so long, and not a single breath leaked, but what was waiting was this moment when Du Fei's breath was relaxed!

No matter which way you look at it, this guy who shot at this time is an absolutely terrifying opponent!

The shadow attacked, the speed was extremely fast, almost in the blink of an eye, and it came behind Du Fei, the fierceness of this kind of offensive is the martial arts ring of the six-rank peak martial arts powerhouse, and it may not be able to withstand it!

"Bell—"

However, at the moment when the shadow was about to fall to the vital point of Du Fei's vest, a white ring containing cold air instantly diffused out, and then, a crisp sound of gold and iron was heard, and the elusive attack was actually blocked.

"Whew-"

With one miss, the shadow figure also retreated in an instant, and then almost instantly fell on top of a stone pillar, looking at Du Fei condescendingly, and then, a slightly playful voice sounded softly: "I have a little ability, I can actually dodge my attack, and the purple gold list ranks ninth, but it is worthy of its reputation!"

Du Fei turned around slowly, his eyes fell on the stone pillar in front of him, and he saw there, there was a man in gray clothes standing there, the clothes on this man's body were extremely weird, as if he could blend into the darkness around him, making his body extremely ethereal, and there was an indifferent smile on his face as if he had seen through life and death, at this moment, when his eyes fell on Du Fei's body, he was like a poisonous snake.

Looking at the gray-clothed man in front of him, a trace of fluctuation flashed in Du Fei's eyes, if it weren't for his instinct between life and death many times, maybe even he wouldn't be able to block that move. And this man in gray can launch such an offensive, not to mention his strength, just this speed and weirdness can make any strong person in the Kyushu battlefield go all out!

"Who are you?" After staring at the person in front of him indifferently for a moment, Du Fei slowly exhaled and said softly.

"Don't you know me?" the man in gray smiled faintly, and after a while, he nodded slowly, "That's right, people like you shouldn't pay attention to those of us who don't even rank on the Purple Gold List...... However, in order to show my respect for you, I will report myself to my home!

"Dark Demon Dynasty?" Hearing this, Du Fei's pupils shrank sharply, and he almost instantly remembered what the origin of this Dark Demon Dynasty was! This Dark Demon Dynasty is also one of the super powers, but in normal times, it is inconspicuous and does not leak. However, this Dark Demon Dynasty is extremely famous on the Xuanwu Continent, because, among the Dark Demon Dynasty, the most famous is the Secret Attack Technique! It is said that the Dark Demon Dynasty has already studied the Secret Attack Technique to the point of perfection, and this so-called Secret Attack Technique, to put it bluntly, is the Assassination Technique!

This Sikong Kong is a person from the Dark Demon Dynasty, so it's no wonder that he was able to use such a strange martial art just now.

......

In the main hall, the moment Du Fei and Na Sikong met, in the golden hall, the eyes of the elders of the Nine Heavens Xuanzong also slowly fell on that picture.

"That person is the Dark Demon Dynasty's commonplace?"

"Hehe, it is said that this Sikong is the most outstanding secret attack master of the Dark Demon Dynasty in the past ten years, it is said that he is a powerhouse of the five-grade low-level martial arts, and he has also been assassinated by him, although he did not succeed, but he was able to retreat with his whole body, this kind of strength can be called terrifying!

"Although this Du Fei is powerful, if you want to defeat this commonplace, I'm afraid it is still very difficult. ”

"Hehe, every time there is a battle in Kyushu, the most exciting thing is this time, no matter what kind of genius, in this situation, he will go all out, I hope to see, these two guys, which one is stronger and which is weak!"

"Dark Demon Dynasty, is it commonplace...... This little guy's luck is really not so good!" Ling Tianzong's old man's indifferent gaze fell on the screen, and after a while, he laughed lightly, at this time, he was really more and more interested in what Du Fei had done!

......

Just above the sky, when the powerhouses of the Nine Heavens Xuanzong had playful expressions on their faces, at this moment, in the middle hall of one of the Nine Towers, the two figures were silently looking at each other.

Du Fei stared at this strong man who was born in a dynasty famous for his secret attack technique, and the solemnity in his eyes gradually flashed, no matter what, such an opponent was worthy of his cautious treatment.

"Okay, haven't you been annoyed by looking at it like this?" A faint smile appeared on Sikongkong's face, he stared at Du Fei, and after a while, he said softly, "Now, since we have finished reporting our home, then, should we be able to start?"

Hearing this, Du Fei smiled and said softly: "Could it be that as a strong person who cultivates the art of secret attack, do you still habitually greet people before you start?"

Hearing Du Fei say this, Sikong chuckled, and immediately saw his soles of his feet step on it, and his figure disappeared strangely out of thin air in an instant!

Looking at the place where Sikong disappeared, Du Fei's brows furrowed rapidly, and then his gaze quickly swept over the shadows around him. From above these shadows, he could feel an extremely strange fluctuation, this so-called secret attack technique cultivated by Sikong was indeed a bit of a doorway, and he was able to completely hide his body in the shadows. Such a method can be said to be extremely troublesome, because if he is no match for his opponent, he can hide in an instant by relying on this means alone, and it is also extremely troublesome to find out.

And with the disappearance of this emptiness, the hall became quiet again, but even so, the killing intent that appeared like a shadow became more and more intense unconsciously......
