Chapter 909: The Soul Devouring Demon
In the stone cave, a scroll of cloth filled with a sinister aura was floating mysteriously, and Chu Mu’s expression was obviously uncertain.

After several years of practice, the dozens of Qingyun Pills that were previously refined have been used up.

His cultivation is still some distance away from the middle stage of the Nascent Soul. Fortunately, with the alliance between the Changsheng Sect and several large tribes on the grassland, the Yanyun Mountains have become a hub for the grassland and the Changsheng Sect.

In addition, with the passage of time, most of the surviving Nascent Soul masters in various parts of the Tiannan immortal cultivation world have gradually moved closer to the only ray of hope, the Changsheng Sect.

In comparison, in this northern border area, the heartland of Yanyun naturally becomes the best place to stay.

The stay of many Yuanying masters in Yanyun also brought many opportunities to him, the lord of Yanyun, and he also obtained a lot of resources at some exchange meetings.

He then picked and chose from the remaining spiritual medicines in the Jizhou treasury, and constructed several fourth-level pill recipes, barely putting together dozens of fourth-level pills.

According to his expectation, if he used up all these pills, regardless of the solidity of his foundation and the residual poison of the pill, he should be able to reach the threshold of the middle stage of the Nascent Soul, and then use the three-pigment Qingyun Pill to force a breakthrough to the middle stage of the Nascent Soul.

Although this would weaken the foundation and leave elixir poison, cultivation is obviously of vital importance in the current situation.

No matter how serious the consequences are, we can find a way to solve them later.

And the result was just as he expected. With his forced accumulation at all costs, he has indeed reached the threshold of the middle stage of the Nascent Soul.

But this time, with a weak foundation and residual poison, it is undoubtedly a fantasy to want to make a breakthrough as in the past with a solid foundation.

The threshold of the middle Nascent Soul stage was like a chasm in front of him. He had wasted half a year without seeing any hope of a breakthrough.

There is no doubt that this bottleneck, like an inconceivable chasm, is caused, firstly, by his poor spiritual root aptitude, and secondly, by the accumulation of a large number of elixirs in just a few years, which has resulted in a weak foundation and residual elixir poison.

According to his past experience, it would take at least several decades to slowly eliminate the poison and consolidate the foundation before there would be a glimmer of hope for a breakthrough.

Then you have to continue to strengthen your foundation until that glimmer of hope for a breakthrough is increased to a level sufficient to achieve a breakthrough.

This process will take at least several decades or even hundreds of years.

However, compared to the Nascent Soul stage, the passing of time is obviously not unacceptable.

But right now...

The urgency in his heart grew stronger, and Chu Mu raised his hand, and the scroll of cloth filled with evil aura was in his palm.

"The Heavenly Demon Soul Devouring Infant Refining Technique..."

Chu Mu looked at the magic cloth scroll and pondered for a while before slowly spreading out the cloth scroll.

This secret magic technique called the Heavenly Demon Soul-Devouring Infant Refining Technique was obtained from that unfortunate demon in the middle stage of the Nascent Soul. He had briefly read through it when he was counting the combat power items before.

He has always avoided such secret magic techniques, let alone in this world full of demons, where such secret magic techniques are even more taboo.

But if he remembered correctly, this secret magic technique, although an evil taboo, also had the effect of forcibly breaking through bottlenecks.

When practicing this secret method, one must use the Nascent Soul as bait to lure the demons from outside the realm to come, and it is inevitable that the demons will devour the Nascent Soul.

But if one can turn the tables and suppress the Heavenly Demon, he can refine a Heavenly Demon Soul Crystal. Using his soul as fire, he can ignite the Heavenly Demon Soul Crystal and transform it into an extremely yin and evil Heavenly Demon soul power.

However, he cultivated the most masculine and masculine method...

The two are bound to be incompatible. Under stimulation, they can turn into a torrent and break through this bottleneck that seems like a natural moat.

The biggest drawback of this method is that it is like a cuckoo taking over the magpie's nest.

If one is unable to resist the demon from devouring the infant, he will inevitably fall into the devil's way completely. In the current world, he may even become a demon.

As for him, with the blessing of a touch of spiritual light, even Tian Yan could not be charmed and clear-minded, and it seemed not difficult to resist the outer demons in the area.

The only concern is that after successfully performing this method, there will inevitably be residual demonic soul power that will infect the spirit, affect the foundation of cultivation, and even affect mental clarity at all times.

If he wanted to completely wipe it out, even if the method he practiced was extremely masculine and powerful, and he even had a magical object like the Great Sun True Fire, it would not be a one-time effort.

"It would be nice if there was spiritual fire..."

Chu Mu sighed sadly. With his current cultivation level having reached a bottleneck, if he could obtain a spiritual fire to refine it, then even if the bottleneck was like an insurmountable chasm, it would surely become a smooth road under the devouring transformation of the Great Sun True Fire.

There is no need to take the risk of practicing this secret magic technique, which would leave many hidden dangers.

"That's it!"

Chu Mu took a deep breath and looked determined.

As his mind was flowing, a ray of spiritual light descended and landed on the scroll of magic secrets in front of him. He began to comprehend the magic secrets recorded on it.

For him, it was not difficult to comprehend this secret method thoroughly.

But this secret method belongs to the devil after all. In today's world, demons are rampant and the world is unpredictable.

No one knew, in this world, whether this kind of secret method belonging to the magic way would also undergo some unknown changes. Especially, he was targeted by Tian Yan, who repeatedly plotted against him...

After flipping through it for a while, Chu Mu seemed to have thought of something, and the cloth scroll suddenly closed. Then, he raised his hand and a space crack appeared. In a flash, he crossed the boundary of the world again and appeared outside the world from inside the world.

The world's halo illuminated his body. Chu Mu stared at the world membrane right in front of him. After pondering for a while, he actually went into the void. He did not stop his flashing figure until he was out of the range of the world's halo.

The chaos is endless, the world is like a mustard seed follicle, moving away, and everything becomes more intuitive and clear.

He had conducted many experiments before, so naturally he had some understanding of this chaotic void.

The Nascent Soul realm only barely has the basis for survival in this chaotic void. This is like the world of immortal cultivation, where ordinary mortals can survive in the immortal cultivation market, but they can only survive.

For ordinary people, any slight change would obviously be a fatal terror.

This chaotic void is what it is like in the Nascent Soul stage.

It's still okay at the edge of the world, because there is a world to suppress the chaotic void. Although there are dangers, as long as you pay a little attention, generally speaking, your life will not be in danger.

But if you go deep into the chaotic void and escape from the world's suppression, everything will be unknown.

He had plucked up the courage to try it once or twice before, and was almost caught in a turbulent flow of the void.

Once caught up in it, with the chaos of the void, no one knows where that moment of confusion will throw him.

And this is just the normal scene that can be seen everywhere. At a glance, there are obviously much more in the vast chaos and void and the unknown horror.

Chu Mu carefully sensed it and confirmed again and again that there was nothing abnormal about the coordinate mark he left behind, then he picked up the cloth scroll again.

With the help of a touch of spiritual light, he was able to do two things at once. On the one hand, he was observing the chaotic void around him, with his mind tense. If he found anything unusual, he would immediately follow the coordinate marks left behind and escape into the world.

Meanwhile, his other mind was analyzing this scroll of the magic secrets word by word, confirming the authenticity of this secret technique bit by bit.

In this chaotic void, there is no distinction between day and night, and it is even more difficult to detect the passage of time. The only person who can serve as a marker of time is Chu Mu himself.

I was so focused that nearly a month passed in the blink of an eye.

When the scroll of cloth was closed, the spiritual light finally faded away.

Chu Mu glanced at the chaotic void, and his gaze returned to the volume of magic secrets in his hand.

"should be no problem……"

Chu Mu pursed his lips and with the help of a touch of spiritual light, it naturally wouldn't take him nearly a month to comprehend this volume of the secret magic technique.

In just a few days, he had thoroughly comprehended this volume of the magic secrets, and the rest of the time was spent simulating the pros and cons of this volume of the magic secrets.

After repeated simulations and speculations, no abnormalities were found.

Outside this realm, and deliberately out of the influence of the world's halo, at the edge of the true realm, the possibility of being interfered by Tian Yan, according to past practice, should not exist...

"Middle stage of Nascent Soul..."

Chu Mu took a deep breath, and in a flash, he returned to the halo outside the world. A flash of knife light fell, and a space crack emerged. The coordinate imprint he deliberately left behind also came extremely clearly from this space crack.

When he was about to return to the world, Chu Mu seemed to have noticed something. His flashing figure suddenly stopped and his eyes were instantly fixed on the halo of the world in front of him.

"This is……"

Chu Mu's gaze suddenly froze, as if it was still difficult to confirm. His gaze, fixed on the halo of the world, also slowly moved over the halo of the world that was visible to the naked eye.

The world is like a follicle. To the cultivators in this world, it may just be a description, and it is difficult to see the truth.

But he had been outside the boundary several times, so he knew clearly that this description was not false.

However, if one really wants to get a glimpse of the true face of the world, one must escape from the scope of the world's suppression and enter the true chaos and void, only then can one barely get a glimpse of the true face of the world.

He was able to confirm this thanks to a glimpse he had gained during his previous adventure.

The outermost layer of this follicle of the world is the world halo. According to some records he knew, the existence of this layer of world halo is a protective film of the world.

However, according to his own research, this layer of world halo does not just have a protective effect, but also has many other mysteries. With his current level of cultivation, he can only vaguely glimpse some traces and it is difficult to confirm.

However, if he remembered correctly, shouldn't this layer of world halo, as reflected in the naked eye, be a flawless white color?

And right now...

The halo of the world within the reach of the naked eye, this pure white...

There are more flaws?
