"Whew-"

As Du Fei's spiritual power took the initiative to diffuse, a tingling sensation suddenly came from the depths of his mind, and as the stinging sensation spread, the lightning that was originally a little illusory became a little more real, and this time it was bombarded, and Du Fei could clearly see that a pill appeared in front of him quite strangely.

"Fight!"

Seeing this scene, Du Fei gritted his teeth slightly, but he had already squeezed his hands violently, ignoring the piercing pain in his head, his spiritual power had instantly diffused out, wrapped in that pill.

"Brush—"

With Du Fei's movements, the pill that was constantly shaking had flashed out of the void space in an instant with the guidance of his spiritual power, and as the pill came out, the ancient scroll trembled slightly, and then under Du Fei's stunned, it slowly turned into a fine dust......

And the elixir that had broken away from the seal was slowly levitating in front of Du Fei at this moment, and on his body, a little cloud and mist vaguely filled out.

"This is the Fog Pill......

Staring at this pill that didn't need to be controlled by himself, it already looked a little weird, Du Fei couldn't help but gasp slowly, and after a while, he quickly ran the pill breath, and after the pain in the depths of his mind disappeared, Fang took a breath and said quickly: "Xiaobai!

"Beep-"

"Because of the master's temporary action, the system broke the seal extremely smoothly, and at the same time, the system was slightly damaged, and in the process of refining the pill in the master's next step, most of them could not have any auxiliary effect, at most they could only remind the master to pay more attention. ”

For the system's calm complaint, Du Fei was slightly stunned, and then wondered: "Refining?"

"Yes, according to the information prompt, if you want to cultivate Dan Teng Driving Mist, you must refine Driving Mist Pill. ”

"Well, then I'll enter the cultivation space first and see how to refine......"

"Beep, the system is damaged, the master can't enter the cultivation space, and a friendly reminder, this Driving Fog Pill, if exposed to the outside world for three hours, will melt on its own, if the master needs it, he has to refine it as soon as possible, and the time is not very sufficient......"

Hearing this, Du Fei was stunned again, he couldn't enter the cultivation space and other things, since he had this unreliable system, it was really the first time he encountered it, after thinking for a while, he couldn't help but smile bitterly, it seemed that in the current situation, he needed to refine this thing alone?

And, without any references?

"Give me the refining information, don't tell me, you can't even do this now, right?"

"Beep-"

"The command is accepted, and the system begins to inject data!"

The electronic sound continued to sound, and in an instant, a stream of mysterious information had rushed into Du Fei's mind, making his head tremble slightly.

After a while, this information flow slowly disappeared, and Du Fei also closed his eyes twice before he slowly opened his eyes, and a wry smile flashed on his face: "I didn't expect that this refining and driving fog pill is so troublesome...... But that's right, with the strength of a nine-rank martial artist, if you want to fly in the sky, such a little trouble is still a small ......"

With a muttered sigh, Du Fei took a slow breath, and several marks had already changed in his hand, and at the end, his right hand was a little sharper at the center of his eyebrows.

With this action, suddenly, the spiritual power in the center of his eyebrows had spread out rapidly, enveloping the Driving Mist Pill suspended in mid-air.

"Whew-"

When the spiritual power was wrapped around the Driving Mist Pill, Du Fei only felt a shock all over his body, and an extremely fierce thought came out of it, so that in the moment he was stunned, his spiritual power had been retracted in a lightning version......

"This Fog Pill has its own soul? or ...... will"

"The answer is wrong, just because refining this elixir requires the demon beast inner pill, and in the demon beast inner pill, the last trace ......of his mind before death is generally sealed, it is not surprising that there will be such a situation."

Xiaobai's calm voice sounded slowly.

"The last thought, how do you know?" Stunned, Du Fei wondered.

"There is a record of similar experiences in the system, and based on this, such a result is inferred......"

Xiaobai still said calmly.

Hearing this, Du Fei was speechless again, and only after a moment did he say lightly: "Then what should happen next?

"The last trace of thought in the elixir is just an idea at most, with the master's spiritual power, there is an eighty percent chance to devour it and refine the Driving Mist Pill......"

"What about the 20% chance?"

"The master will be consumed by this violent thought, and become a walking corpse that only knows how to kill......"

"Uh...... I'll wipe it!" The muscles on his face twitched slightly for a moment, and Du Fei couldn't help but say loudly.

"Because of this, the system suggested that the master give up cultivating this pill technique, although refining the Fog Driving Pill has the benefit of flying in the sky, and even has the benefit of increasing spiritual power, but it can't withstand that dangerous ......."

Hearing this, Du Fei's face twitched again, but after a while, a trace of fierceness flashed in his eyes, and he immediately smiled faintly, and said: "When did your unreliable system learn to fool people? But since there are so many benefits, why should I give up? This step by step, I have not once passed without the slightest danger......

With a faint laugh, Du Fei clapped his hands, and a spiritual power slowly diffused out, instantly wrapping around the pill.

"Whew-"

At the moment when he closed his eyes, Du Fei clearly felt that the thoughts that permeated the elixir were like poisonous snakes, following the spiritual power that Du Fei pasted, as if crazy, and slammed into Du Fei's brain.

This kind of spiritual power attack, Du Fei can be regarded as the first time he has encountered it, therefore, he was shocked, but his face suddenly turned a little pale.

"Concentrate, hold your breath, and run the Dan Breath Chapter ......" Although Xiaobai is unreliable, at this time, it is quite a calm reminder.

The corners of his eyes twitched slightly, the mark in Du Fei's hand had changed rapidly, and his spiritual power also formed a point in the depths of his eyebrows with the movements in his hand, and slowly swirled......

With this action of his own, Du Fei clearly felt that the moment those poisonous snakes hit his spiritual power, they bounced back fiercely as if they had hit a wall.

But in just an instant, those poisonous snakes formed by the mind collided with each other again like a mountain and a sea.

This kind of offensive opened in waves, and every impact made Du Fei's spiritual power feel a powerful impact, and his face changed again and again.

He didn't expect that the last thought of this demon beast before dying would be so strong.

You must know that ordinary demon beasts can only condense demon crystals in their bodies at most, and only demon beasts that have reached the sixth-order demon king level can condense inner pills in their bodies.

And this Inner Dan, although I don't know what grade of the demon king condensed, but you must know that the strength of the demon king is already equivalent to the strength of the human martial sect.

And the strength of the ideas left behind has long surpassed Du Fei's imagination.

As waves of spiritual attack power came, Du Fei only felt like a boat in the midst of stormy waves, and the boat would capsize at any time.

At the beginning, Du Fei was still able to use his mental power to protect his whole body, but in the end, he could only hold on to the key points of his eyebrows, so that his mind would not be eroded by the violent thoughts.

This battle of spiritual power lasted for a full hour, and in the end, it ended with the defeat of the violent mind. Originally, Du Fei had no chance of winning at all, but fortunately, this trace of violent intent no longer knew how many years had been sealed in this elixir, so it was already weakened to the extreme, otherwise with Du Fei's strength, I am afraid that it would not be long before he would be devoured by it.

He exhaled slowly, and after the violent thoughts dissipated like a tide, Du Fei's whole body relaxed, and his face was extremely pale.

"Congratulations master, you have resisted the invasion of the hidden thoughts in the Driving Mist Pill, next. You only need to devour the spiritual power contained in that trace of thought, and then refine the Driving Mist Pill!"

"Xiaobai, you are really becoming more and more reliable!" Du Fei complained calmly, and only then did he touch the cold sweat from the corner of his forehead, but he also knew that he had no time to rest this time.

Slowly taking a breath, Du Fei's hand marks changed again, and the spiritual power spread out rapidly, and with the spread of spiritual power, Du Fei felt this time that the kind of violent intent that was originally permeated on the Fog Pill had turned into a translucent crystalline substance at this moment.

"Is this the spiritual essence ......?"

Seeing this scene, Du Fei's spirit moved slightly, but he remembered a term in the Danxi chapter.

It is said that this spiritual essence is condensed by the dying thoughts of some powerful demon beasts, and if it can be devoured, it can not only increase its spiritual power, but also make its own spiritual power have a kind of coercion like that of demon beasts.

And these things that appeared at this moment were no different from the spiritual essence in the description.

And the owner of this thing is extremely fierce, but Du Fei has already understood it just now, if he can refine these things......

"Hehehe......"

With a soft laugh, Du Fei had already carefully probed out a trace of spiritual power, wrapped a small part of it in it, and then slowly refined it with the Dan Breath Chapter.

And with this kind of refining, Du Fei clearly felt that the spiritual power in his eyebrows was instantly strengthened, and after a while, a faint vortex of spiritual power was formed......

"Mental Power Vortex ......"

Sensing this scene, Du Fei had already understood that he could now truly be regarded as a Jiupin Dan Master.

Because, this spiritual power vortex is the basis of the Danshi, and there is one storm that is called the ninth grade, two paths, which are eight grades, and three paths, which are seven grades......

Such a little spiritual crystallization allows himself to have this benefit, if he devours it all......

Thinking of this, Du Fei was unceremonious, and he had already followed the extremely fast speed of devouring, and his spiritual power quickly diffused out......
