The black flame seems to have existed since ancient times. If you look closely, you can find that these black flames have burned even the space into nothingness, and even the Void Demon Thunder has no meaning in front of it.

Du Fei squinted at the black immortal flame for a long time before he slowly exhaled. No matter how you look at it, in any sense, the strength of this immortal flame is beyond Du Fei's imagination.

After being silent for a long time, Du Fei flicked his fingers slightly, and a yuan force instantly roared out.

"Whew-"

However, the moment the Yuan Force fell on the black immortal flame, the black flames instantly burned Du Fei's Yuan Force into nothingness.

Seeing this scene, Du Fei frowned slightly, and then flicked his fingers again, this time a wisp of telekinesis roared out, but the result was still the same, there was no difference.

This scene made Du Fei frown slightly, even he didn't expect such a result, and if he was allowed to directly get a trace of fire at this moment, even Du Fei would not have the courage. After all, the strength of this immortal flame was already a bit beyond Du Fei's imagination.

After frowning and staring at the immortal flame for a long time, Du Fei sighed and said, "Xiaobai, for the time being, I can't think of any good way to obtain this wisp of immortal flame, do you have any better way?"

"This ....." Xiao Bai was silent for a moment before he hesitated slightly, "Master, this immortal flame was left by the ancestor of the ancient Tianfeng clan, I think it is not so easy to obtain it by ordinary means, even if it is a trace...... However, if it was someone from the Ancient Heavenly Phoenix Clan, there might be a chance...... Therefore, if the master uses the Heavenly Phoenix Immortal Sutra to the extreme, there may be a chance. ”

"What if your speculation is wrong?" Du Fei frowned, he hadn't thought about this idea, but this immortal flame was too dangerous, so dangerous that even Du Fei couldn't try it for a while.

"Rich and noble, master, haven't we all done this for so long? if something happens, as long as we give it up, it shouldn't be a big problem!" Xiao Bai said intently.

"Is it dangerous to be rich and rich?" Hearing this, Du Fei was silent for a moment before gritting his teeth and saying, "What you said is indeed the truth, since this thing has been discovered, then no matter what, you can't go back empty-handed this time!"

When the words fell, Du Fei had already stepped on the soles of his feet, and in an instant, nine dazzling heavenly phoenix light patterns appeared on the surface of his body, and at this moment, the aura on Du Fei's body instantly soared to the extreme.

Under the shroud of the seven heavenly phoenix light patterns, Du Fei slowly stretched out his palm, and in the next moment, a crazy suction appeared in the palm of his hand. The targets of these suction forces were naturally those immortal flames, and when the suction power emerged, the originally quiet immortal flames seemed to come to life and began to dance constantly.

"Whoa—"

In the quiet space, suddenly, there was an ancient and vast sound of phoenix chirping, as if this sound was left from the primeval period and passed through time and space, and only appeared at this moment.

And the existence of this voice also made Du Fei's spirit tremble slightly, and a tingling sensation suddenly came out of the center of his eyebrows.

However, Du Fei did not give up at this moment, but gritted his teeth, so that the suction in his palm continued to become stronger at this moment!

"Sneer—"

This time, under the violent suction, a faint trace of black flames began to be sucked out of those dazzling immortal flames, and then these black flames followed Du Fei's Yuan Power and gathered rapidly, but in the end, they slowly fell to Du Fei's palm and converged into a flame the size of a little thumb.

"It's done!"

Looking at this scene, Du Fei hurriedly stopped his previous movements, and then stared at the glimmer of fire in his palm, with a happy look on his face.

"Master, you must not be so happy so early! What you have to do next is to completely refine this trace of flame, and the danger is extremely high...... And only by refining this flame of immortal flame can you have a chance to step into the realm of nine patterns returning to one. Xiaobai said softly.

"I understand. Du Fei nodded, and then sat down cross-legged on the spot without the slightest hesitation, and then the imprints of his hands changed slightly, and he saw that the wisp of immortal flame in the palm of his hand had disappeared in Du Fei's palm, and then slowly followed Du Fei's meridians.

"Whew-"

Wherever the immortal flame reached, Du Fei's meridians were scorched and distorted, but because Du Fei had already suffered from the relationship between the reshaping of the origin of the ancient holy fire, he was able to persevere, although this wisp of immortal flame could bring him some damage, but it couldn't bring him too much substantial damage.

With the advance of the immortal flame, the meridians in Du Fei's body became a mess almost instantly, but Du Fei still gritted his teeth and persevered, relying on his mind to guide the immortal flame towards the place where the primordial spirit was located in the place of his dantian qi sea.

Yuan Ling, who was suspended in the sea of Du Fei's dantian qi, was originally sitting cross-legged, but at this moment, it suddenly opened its eyes, and a solemn look appeared in its eyes, and the little face that was almost exactly the same as Du Fei's expression was solemn.

"Whew-"

Soon, this black immortal flame passed through Du Fei's meridians and came to the place of the dantian qi sea, although it was light, but the extremely terrifying heat covered Yuan Ling's body almost at this moment, making Yuan Ling's little face more and more solemn.

However, at this moment, the imprints of Yuan Ling's hands were also changing rapidly, and suddenly nine small heavenly phoenix light patterns appeared on the surface of Yuan Ling, and then between the seven colored lights, the black immortal flame slowly moved towards the place where Yuan Ling was.

Time passes minute by minute.

In the outer room, Du Fei still maintained a posture of sitting cross-legged, but the nine heavenly phoenix light patterns on the surface of his body vaguely felt a little unified.

At a certain moment, Du Fei suddenly opened his eyes suddenly, and a trace of black light flashed in the depths of his eyes, but at the same time, his face was happy.

In Du Fei's dantian qi sea, at this moment, Yuan Ling was holding the black immortal holy flame in his hand, and the black immortal holy flame was wisps of it, slowly drifting in all directions, slowly blending into Du Fei's Tianfeng true qi, and began to slowly change the nature of Du Fei's true qi and even his physique.

This process should be extremely slow, but it is foreseeable that after the success of this process, Du Fei's strength will skyrocket again!

"Congratulations to the master, you have successfully refined the Immortal Flame!" Xiao Bai's voice appeared in Du Fei's mind, obviously, it was also a little surprised, because even it didn't expect that things would go so smoothly. You must know that in the face of the immortal flame, if something is not right, the ending will be extremely unbearable.

"It can only be regarded as a reluctant success, and it will take a long time to accumulate in the future before we can truly achieve the unity of the nine lines. But even so, what we have to do in this ancient sacred mountain has come to an end, and it is time to leave. Du Fei stood up slowly, twisted his neck, and then said with a little sigh.

"Indeed, master, let's go. Xiao Bai also nodded, they had been in this ancient holy mountain for too long, and they had to leave immediately at this moment, because Du Fei didn't have that much time.

After taking one last look at this strange space, Du Fei saluted the ancestor of the ancient Tianfeng clan from afar, and then his body moved, and he instantly rushed towards the sky.

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

In the outside world, Feng Qishan and the others have been waiting outside for nearly two months, but in the past two months, the Ancient Holy Mountain has been calm, and no one knows what is going on inside.

At the beginning, the people of the ancient Tianfeng clan were still rejoicing, it seemed that Du Fei was really able to withstand the Tianfeng Holy Fire, and now he must be reshaping the origin. But as time passed, this kind of happiness turned into worry! Because, according to the calculation of time, even if Du Fei came into contact with the Ancient Flame, he shouldn't have spent so much time!

And at this moment, almost everyone, including Fengqi Mountain, wanted to know what was going on in this ancient holy mountain.

However, nervousness is nervousness, Du Fei does not appear, and it is impossible for them to rush in directly to arrest people, because, at this time, they can only look at each other helplessly, and then wait with a little worry.

And such a wait, another month of waiting has passed.

For a month, the Ancient Sacred Mountain remained calm, as if no one had ever entered it.

And when things got to this point, the faces of Feng Qishan and the others also became a little ugly.

"Supreme, Elder Du Fei, there shouldn't be anything, right?" An elder finally couldn't help but speak, it's been so long, why hasn't there been any movement at all? If Du Fei has anything to do, then their Ancient Heavenly Phoenix Clan's face this time will really be embarrassed.

Feng Qishan hesitated for a moment, but he could only smile bitterly, he really didn't know what was going on at this moment!
