On the platform where the Xuanyin Stone was located, I don't know how many people's stunned eyes fell on Du Fei's body at this moment, and a look of horror flashed on his face. Du Fei was actually able to withstand the oppressive power of the Xuanyin Stone's closest distance, and then refine the Xuanyin Qi......

This is beyond the imagination of too many people!

And outside the platform, a trace of strangeness flashed in Mu Yuxia's eyes, she stared at Du Fei, and after a while, a trace of surprise flashed on her face, this Du Fei was not only able to resist the erosion of the Xuanyin Qi, but also knew how to refine the Xuanyin Qi at such a time...... This guy's perseverance is really beyond imagination!

"Over the years, the only one who has been able to do such a thing is our senior brother of Sky Wolf Peak...... Du Fei, if you can do it, presumably, our Heavenly Wolf Peak will be much more exciting from now on!" Mu Yuxia's eyes were full of different colors, in her opinion, even if the peak master Leng Ping knew about this, I am afraid that he would also be shocked, right?

"It seems that this little guy is a good choice to join Sirius Peak. ”

"Whew-"

For the various eyes around him, Du Fei at this moment had no time to perceive it, his spirit, in addition to dealing with the constant influx of Xuanyin Qi, also needed to be used to refine those obscure energies, so that his True Qi could completely transform its nature.

And with the passage of time, gradually, the true qi and Yuan Dan in Du Fei's body have all been covered by the Xuanyin qi, and even between Du Fei's breathing, there is a faint white mist, as if the nature of his entire true qi has been completely changed.

"Is this first step a success?"

Sensing such changes in Du Fei's body, Du Fei couldn't help but feel a slight jump in his heart, if he hadn't been a little aggressive this time, if he wanted to completely change the nature of the true qi in his body, I'm afraid it would take at least a month's effort, right?

"Since the transformation of true qi has been successful, the next thing to do is to turn yin?"

After exhaling slowly, Du Fei raised his head again and stared at the Xuanyin Stone in front of him, and a faint brilliance flashed in his eyes. As long as one's spiritual power enters this Xuanyin Stone and goes through some kind of trial, even if he succeeds in transforming Yin, he can truly cultivate that Xuanyin Qi, right? I don't know if this kind of cultivation is good for me, but since I have come to this point, then I have no way out!

Slowly closing his eyes, Du Fei's mind moved, but in an instant, his spirit was slow, and he immediately sensed that everything around him had become different.

"It's actually starting to turn yin, and it's been less than a day... This little Du Fei is really beyond imagination! If he can successfully transform yin today, then he can be regarded as one of the few people in my Heavenly Wolf Peak! Since the establishment of my Heavenly Wolf Peak, there are two people who have successfully transformed yin in one day, and if he does it, he will be the third person!" Mu Yuxia squinted her eyes, her beautiful eyes were full of brilliance, this Du Fei brought her surprises, there were really a lot of halls!

"What? That guy has actually successfully transformed the True Qi and Yuan Dan in his body? How long has it been?"

"Not only that, but most of his current spiritual body has begun to enter the Xuanyin Stone and induce Yin?"

"How the hell did this kid do it?"

Those Heavenly Wolf Peak disciples who were cultivating on the platform seemed to have seen something at this moment, and suddenly, their faces became a little strange. This Du Fei could do such a thing in just one day's effort, wouldn't this make it seem like the rest of them were like waste?But, at the same time, there was also a trace of strangeness in the hearts of these Heavenly Wolf Peak disciples.

This Heavenly Wolf Peak has been controlled by the current Seven Core Disciples for several years, and over the years, although many people have continuously challenged the Seven Core Disciples, none of them have succeeded! After all, those harmonious disciples are cultivating the most top-level exercises and martial arts in the Heavenly Wolf Peak, how can they be compared to ordinary inner disciples?

And at this moment, this Du Fei was born, just like the senior brother back then, and did such a dazzling thing, could it be that this indicates that the pattern of this Heavenly Wolf Peak is going to change again? If this is really the case, then maybe these people are not without a chance!

As soon as they thought of this, many people stared at Du Fei's line of sight, and there was a faint weird taste.

............

When Du Fei's spiritual power stabilized again, he found that he had appeared in a vast land.

This land is extremely vast, it looks like a flat river, and occasionally some ancient buildings appear abruptly on the heaven and earth, but it forms the most primitive embellishment, making the world appear more and more vast.

In such places, an ancient and vicissitudes of life permeated the heavens and the earth, as if Du Fei had traveled through time and space and came to the ancient period.

Du Fei took a deep breath, glanced at the dilapidated building under his feet, and then looked up at the sky again. Suddenly, a feeling of extreme insignificance arose, and with the perseverance of Du Fei's mind, a sense of powerlessness also emerged at this moment!

"Whew-"

Slowly exhaled, Du Fei's eyes became sharp, if he was not mistaken, this should be the spiritual space in the Xuanyin Stone! Moreover, the spiritual space of this Xuanyin Stone is most likely a simulation of the ancient battlefield where the ancestor of Heavenly Wolf Peak obtained the Xuanyin Stone back then! If this is the case, it is definitely impossible to be so peaceful here......

Thinking about the induction when he saw this Xuanyin Stone for the first time, Du Fei couldn't help but shudder in his heart slightly, if it was just like what he sensed, then the trial of this Xuanyin space, the transformation of Xuanyin Technique, would definitely not be easy to go anywhere!

Taking a deep breath and quickly suppressing the chill in his heart, Du Fei slowly sat down cross-legged on the building under his feet, and then slowly breathed.

If you don't take advantage of this time to adjust your state to the peak, then I'm afraid you may not be able to get through this hurdle later!

"Woooo

Just after Du Fei breathed for a while, suddenly, from all directions, there were bursts of wind breaking sounds.

Sensing such changes, Du Fei raised his head violently, and his gaze fell to the sky. At this moment, above the sky, you can see that the black dots are constantly getting bigger, and in the end, they turn into shadows, and almost in the blink of an eye, these black figures are all over the world!

However, these figures that appeared were clearly divided at the moment, centered on the building where Du Fei was sitting, these people were obviously divided into two groups of forces, and each other seemed to have a huge killing intent, because, although no one spoke at this moment, there was already a boiling killing intent emerging between heaven and earth!

"It's... Is that the source of the Xuanyin Qi?" staring at this scene, Du Fei couldn't help but mutter as if he had noticed something. Could it be that this Xuanyin Stone is still condensed by the killing intent emitted by I don't know how much power in this ancient period? If this is really the case, the origin of this Xuanyin Stone is probably not simple!

"Bang-"

When Du Fei muttered, the two groups of centaurs between heaven and earth seemed to be alarmed by something, without any words or temptation, almost between the next breath, the two groups of centaurs suddenly burst out at the same time, and then crashed together!

"Boom-"

Between heaven and earth, the sound of a powerful true qi eruption instantly spread, but in the blink of an eye, I don't know how many strong people fell instantly, and I don't know how much blood and water spilled all over the world, just a breathing exercise, this piece of heaven and earth has all turned into a heaven and earth killing field, even the sky, at this moment, is all red by blood and water!

"Is this the Great War of the Ancient Times?"

Du Fei squinted at the scene in front of him and slowly exhaled, obviously, this scene in front of him was real in ancient times. And the most terrifying thing for himself is that with his strength, if he joins such a battle, I am afraid that it will only be a breath of time, and he will completely fall.

This... What a level of battle!

The battle continued continuously, between heaven and earth, there were constantly strong people like falling birds, smashed to the ground, and then sprinkled the blood and water all over the sky, and more strong people were directly beaten into a pair of minced meat in the sky, and there was no way to leave even a little meat residue!

Looking at the increasingly fierce battle, gradually, the number of people began to decrease continuously, and in the end, those who were doing it no longer fell at will, because they could remain in this heaven and earth killing array, none of them were the most powerful powers......!

And what should you do in such a situation?

After exhaling slowly, this question surfaced in Du Fei's mind, although the battle that appeared at this moment was tragic, but it didn't seem to affect him, so, what are you going to do? Or rather, what is this trial?
