"Whew-"

In the air, there were faint streaks of illusory white smoke passing by, and then, before Du Fei could react, the spiritual essence that was originally slowly refining suddenly surged towards Du Fei's eyebrows in an already rather strange posture.

"Poof—"

Du Fei, who was originally normal on his face, suddenly opened his mouth, but a mouthful of blood spurted out violently.

"Bang-"

The clothes that were originally wrapped around his body also burst into powder in an instant, and on his skin, curves like earthworms suddenly appeared, constantly writhing, this scene made Du Fei's figure become weird to the extreme.

And this strange feeling, Du Fei couldn't clearly feel it, the only thing he could feel at the moment was that the original rather well-behaved spiritual power was like crazy at the moment, and it had been spinning wildly, fused with the spiritual essence of those who had a bit of crazy posture, constantly distorting.

And with the fusion of the two, the spiritual power that had been cultivated almost without progress in the past was also growing rapidly at this moment, as if it had been beaten with chicken blood.

And this kind of spiritual power growth, but Du Fei's mind stinging sensation continued to come out, the newly formed spiritual power vortex, as if it could not withstand this kind of strong spiritual power, there was a feeling of being violently supported almost instantly.

This feeling made Du Feizhi feel like he was in a cold sweat.

He didn't expect that this refining spiritual essence was actually so dangerous.

It's just that at this time, he can't regret it, he can only use his mental power to quickly suppress this painful feeling. And this almost maddening pain stimulated Du Fei to almost want to jump up and roar.

But Du Fei also knew that if he made such actions, his life would be considered useless!

At this moment that almost tortured Du Fei to madness, Xiao Bai's cold voice suddenly sounded......

"The volume of Dan breath, with Dan as the guide, the breath leads to yin and yang, yin and yang divide the world and the earth, and the sun and the moon are incomparably ......"

Although Du Fei knew this mantra, he had never cultivated it, but at this time, he suddenly understood that this was the second layer of the Dan Xi chapter!

The first layer of the mental method, after Du Fei condensed the first spiritual power vortex, had already lost its effect, and now?

Thinking of this, Du Fei didn't care about anything else, since Xiaobai reminded him, it was always right.

Therefore, after gritting his teeth a little frantically, he had already sat cross-legged quickly, the imprints in his hands were constantly changing, and his spiritual power had been running wildly according to the running veins of the Dan Xi Chapter.

And in this case, no matter how much cultivation was in the past, it was an extremely slow progress of spiritual power, but at this moment, in a posture that was so fast that it was maddening, almost just an instant, but it had already been cultivated.

And the spiritual power vortex in the depths of Du Fei's eyebrows, after trembling slightly for a moment, had already split into two ......

"Eight Rank Dan Master!?"

Seeing this scene, Du Fei couldn't cry or laugh for a while, but before he could finish his happiness, the impact of the spiritual essence came again, seeing this kind of essence that was like an endless essence, Du Fei didn't know what to think in his heart, the mark in his hand changed again, and he had already cultivated rapidly.

It's just that this time, with his previous experience, Du Fei had already recited the third layer of the Dan Xi Chapter in his heart without hesitation, and he quickly cultivated.

And this time, it was still the same as before, almost in the blink of an eye, Du Fei had already condensed the third spiritual power vortex, that is to say, his strength had reached the realm of the Seven Rank Dan Master......

If it was an ordinary Dan Master, knowing that Du Fei had actually completed the breakthrough from the ninth rank to the seventh rank in just a few minutes, I don't know how many people would be scared to death on the spot.

You must know that spiritual power cultivation is many times more difficult than true qi cultivation, and many people often devote their lives to it, and they can't take another step in spiritual power cultivation......

And just when Du Fei condensed the third spiritual power vortex, he clearly felt that there seemed to be a strange connection between these three spiritual power vortexes, as if they wanted to fuse their three vortices back together, but at this moment, there was something blocking them, so that they could not fuse.

But even so, these three spiritual power vortex were still spinning wildly, devouring those remaining spiritual power essences, and also causing the spiritual power vortex to continue to expand......

However, no matter how it expands, it seems that the last layer of obstacles cannot be broken......

It's just that with the passage of time, Du Fei felt extremely clearly that there were already some indescribable things in the heart of his eyebrows, as if it was like a sea of dantian qi, and his spiritual power had been condensed to that place.

"Boom-"

At a certain moment, the last trace of spiritual essence was swallowed up by Du Fei's spiritual power vortex, and the connection between the three spiritual power vortices seemed to be a little closer, and with the disappearance of the spiritual essence, the pain in Du Fei's head also disappeared, replaced by an indescribable sense of pleasure......

"Seven Rank Peak Dan Master!"

His eyes opened suddenly, and an extremely strong spiritual force rippled out from the center of Du Fei's eyebrows, and almost in an instant, it spread all over the entire wolf's mouth, in this instant, everything in the wolf's mouth was under Du Fei's eyes, and even Du Fei clearly felt that if he wanted, he could control the will of ninety percent of the creatures in the wolf's mouth and make it his own use......

It's just that Du Fei didn't do this, as soon as his spiritual power was collected, it had already condensed into a strand, and instantly swung out towards the depths of the jungle beyond the wolf's mouth, and when he sensed a demon beast, the invisible spiritual power had been violently condensed into the shape of a palm, and he immediately pinched it gently!

"Poof—"

The demon beast had already been pinched into minced meat at the moment before it could react, and in an instant, the spiritual power that diffused out disappeared in an instant at this moment......

"Whew-"

In the room, Du Fei took a breath slowly, just now, he had used his spiritual power to the extreme, and what he could do made his heart full of shock!

It's a seven-rank martial artist, and its strength is nothing more than that!

And what he can do, the seven-rank martial artist may not be able to do!

"It turns out that the Dan Master is not only powerful in alchemy, but also so powerful in this spiritual power? This invisible and traceless means, although it is not as powerful as the Dan Technique, but it is countless times more tricky than ordinary martial arts, no wonder ordinary people dare not provoke the Dan Master when they die......

"There is a skill to use mental power to manipulate the elixir, I don't know if there is a skill to directly manipulate mental power......

After being shocked for a moment, Du Fei muttered to himself, but in his eyes, different colors kept flashing.

Although the Dan Xi chapter is only a method of cultivation, and there is no other record in it, if he can get some related things in the Danwang ruins this time, presumably, his strength as a seven-rank peak Dan master can also be brought into full play......

As soon as he thought of this, Du Fei couldn't help but have a little urge to laugh loudly, but now he was able to control his emotions very well, but after a moment of excitement, he had calmed down, and his eyes were once again staring at the pill in front of him.

"What the hell is this coming from...... How can it have such power...... I don't know if I have the kind of violent intent in my mental power, and if so, wouldn't it be another benefit?"

It's just that, having said that, Du Fei didn't have time to test such things as coercion at the moment, and at the moment, he could only restrain a little doubt in his heart, and his eyes fell on the Driving Fog Pill in front of him again.

"The next thing to do is to refine this Fog Driving Pill, and then cultivate the Dan Teng Fog Driving Fog, right?"

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

In the courtyard, Yun Yuqing, who was originally recuperating with his eyes closed, suddenly shook slightly, and an indescribable strange feeling came to his heart, this feeling was extremely strange, as if there was an extremely dangerous thing around him.

After hesitating for a moment, Yun Yuqing's gaze fell on the attic protruding from the courtyard, and a look of hesitation flashed in his eyes: "It shouldn't be the damn Du Fei...... It's not that I don't know his strength...... Even if I cultivate for a few more years, it won't give me this feeling, it's just ......"

The mouth of the wolf, the general soldier's house.

Long Lingtian, who was originally squinting at the book in his hand, suddenly shook slightly, but his eyes suddenly turned in one direction......

"Mental power coercion...... This coercion has a bit of the breath of the dragon clan...... However, there is something strange about it...... Is this someone demonstrating with me?"

After muttering for a moment, Long Ling Tiancai smiled faintly and said to himself: "It seems that this battle for the Danwang Ruins is a lot more interesting...... I hope this guy doesn't let me down......"

After that, Long Lingtian's face had returned to normal, and after a while, he continued to slowly look at the book in his hand.

Behind her, Long Yan'er, who was originally cold-faced, changed her face slightly at this moment, and became extremely strange after a while.

Long Yan'er knew extremely well that this extremely arrogant guy in front of him was the leading alchemy genius in the Yunshui Long family, this time, the family could invite him to help, but he paid a great price, and it was expected that if he had him, he would definitely win this time.

But I didn't expect that Long Lingtian, who had always looked down on the Wolf's Mouth and the power in Heavenly Snake City, would say such things......

On the outskirts of the wolf's mouth, in a pitch-black crypt, a guy who was wrapped in darkness suddenly moved slightly, and after a while, a voice that was difficult to hear was extremely loud, and slowly sounded: "Interesting...... Interesting...... It seems that this time, I can have a good time...... Hahahaha......."
