Now there is also the 'Supreme Demon Wall' imitation wall here, and Huang Xiao wants to make good use of it.

Because he knew that the patriarch might let him pass at some point, then this imitation wall would definitely not be able to be taken away, and then he would not be able to enjoy the benefits of demonic qi infusion.

The 'Supreme Demon Wall' imitation wall has been moved to a secret room next door, connected by a stone door in the middle.

Huang Xiao pushed the door and entered, and saw the imitation wall in the center of the secret room.

With a long exhalation, Huang Xiao walked to the imitation wall and sat down cross-legged, he did not immediately stimulate the 'Supreme Demon Qi', but was ready to refine his Heavenly Demon True Qi first.

After a while, Huang Xiao calmed down.

When the heart moves, the essence and blood are stimulated, and the essence and blood rush to the heart, and the heart is on fire.

Huang Xiao controlled his heart fire and began to infiltrate the meridians, and then began to calcine his Heavenly Demon True Qi with his heart fire.

Burned by the fire in his heart, the Heavenly Demon True Qi soon began to change, and the Heavenly Demon True Qi that was originally filled with meridians quickly began to shrink and decrease, which was a decrease in quantity, but the aura became more powerful.

The essence blood was constantly stimulated, and the heart fire was constantly generated, and the meridians in Huang Xiao's body could be said to be filled with heart fire, and these heart fires were constantly calcining the unrefined Heavenly Demon True Qi that had newly poured in from the dantian.

is also because of several experiences, Huang Xiao is now familiar with such situations.

The Heavenly Demon True Qi in the meridians became more and more condensed, and the aura became more and more powerful.

Huang Xiao knew that he had succeeded in refining his True Qi, and his Heavenly Demon True Qi had increased a lot.

However, he could still feel that his current improvement had not yet reached the limit, and that was because his Tenth Heavenly Demon Skill had not yet been completed.

Compared with refining magic tricks, Huang Xiao felt that this was his advantage.

Because refining the magic trick can only be carried out when each skill is completed, the refining of true qi can be carried out, and he does not have such trouble.

Although he had now refined the Heavenly Demon True Qi, as his skills improved, he could also continue to refine it.

As for whether Pang Yi has other ways to increase the strength of his true qi, Huang Xiao can't guess, it is very likely that there is, and it may not be as effective as refining the magic technique.

After all, there is still Pang Ji, a supreme patriarch, behind him, and everything can't help but think about the worst.

Half a day later, Huang Xiao stopped.

Because he found that now that refining True Qi had reached the limit, he could only wait for his strength to improve a little more if he wanted to continue refining.

This time to refine the true qi, Huang Xiao still consumed a lot of essence blood, and he felt that it would take him ten days and half a month to make up for the loss of essence blood.

The consumption of essence blood exceeded his expectations, mainly because the true qi of the Martial Realm realm was much deeper and stronger than that of the Void Martial Realm, and the essence blood consumed was naturally more.

With Huang Xiao's current state, it is not good to continue to stimulate the 'Supreme Demon Wall' imitation wall.

"Huh?" Huang Xiao's eyebrows suddenly moved, and he noticed that there was something strange in his body.

After feeling it carefully for a while, Huang Xiao was pleasantly surprised to find that his essence and blood recovery speed was extremely fast, at least several times or even more than ten times that of before.

At this rate, Huang Xiao felt that it would take him a day or two to recover the essence blood he had consumed.

After a while, Huang Xiao realized the reason for this miraculous situation.

Huang Xiao could feel his heart beating wildly, more vigorously than usual.

That burst of contraction, and then when he stretched, every time Huang Xiao could detect the appearance of new essence and blood.

Not only that, Huang Xiao was also able to discover that the 'Immortal True Qi' in his body did not know when it seeped out from the meridians, stimulating the heart.

The changes in the heart are obviously related to the 'Immortal True Qi'.

"It's still related to the 'Immortal Chapter'. Huang Xiao thought secretly in his heart.

Whether it is the heart fire or the 'inextinguishable true qi', it is all related to the 'immortal chapter', why this situation occurs, Huang Xiao himself can't say clearly, since he mastered the method of heart fire stimulation, such magical effects have appeared one after another.

However, he believes that this is the magic of the 'Immortal Chapter', which is only good for himself, not bad.

As for whether this 'Immortality Chapter' can make him truly immortal, Huang Xiao can't believe it, but now he is giving himself the benefits, Huang Xiao believes it.

He had already really felt that whether it was the heart fire refining true qi or the magical effect of the 'Immortal True Qi', his strength had increased many times.

Huang Xiao still doesn't know the true power of the 'Immortal Chapter', but he believes that as the magical effects of the 'Immortal Chapter' continue to emerge in him, he should be able to crack the secret of the 'Immortal Chapter'.

The magical scriptures that can be as famous as the 'Immortal Chapter', the unimaginable magic, is definitely far more than that, Huang Xiao is looking forward to it in his heart, looking forward to more surprises.

"Before the immortal true qi was extinguished, the meridians and flesh and blood could be repaired, but I didn't expect that even the essence blood could be quickly generated now, so if you want to refine the true qi in the future, you are not afraid of consuming a large amount of essence blood. Huang Xiao thought again.

Next, Huang Xiao didn't think much about it, and quietly felt the continuous contraction of his heart and the continuous generation of essence and blood.

A day and a half later, Huang Xiao found that his essence blood had completely recovered, the same state as before refining his true qi, and even better spirit.

At this time, Huang Xiao began to stimulate the 'Supreme Demon Qi' in the imitation wall.

These demonic qi were quickly incorporated into the meridians by Huang Xiao, and the demonic qi impacted his meridians, and also strengthened the Heavenly Demon True Qi after his refining.

Although this kind of enhancement is not as obvious as refining, these are supreme demonic qi after all, and they still have a lot of improvement on Huang Xiao's meridians and heavenly demon true qi.

These were not Huang Xiao's main purposes, his main purpose was to obtain the refining supreme demonic qi that he could barely control by reversing the refining method.

Thinking of this, Huang Xiao didn't hesitate any longer, his heart fire was stimulated again, and this time he withdrew all the Heavenly Demon True Qi in his meridians into the dantian.

The meridians were now filled with Supreme Demonic Qi, and then these heart fires began to scorch the Supreme Demonic Qi, and he only chose a small part of the meridians.

I don't know how many times stronger the Supreme Demon Qi is than my Heavenly Demon True Qi, and if Huang Xiao wants to reverse and refine a trace of the Supreme Demon Qi, he has to consume ten times or more of the previous Heart Fire, and he can't calcine the Supreme Demon Qi in the meridians at the same time.

It was also thanks to Huang Xiao that he knew that he could quickly make up for the consumed essence blood, so he dared to do this, otherwise if he continued like this, it would take a lot of time to recover.

At the beginning, he used the 'Demon Blood Pill' to restore the consumed essence blood, but now he knew very well that even if he had the 'Demon Blood Pill', he was afraid that the effect would not be as good as his 'Immortal True Qi'.
