In the secret realm of the ancestral spirit, in the tops of the towering trees, Duan Chen was carefully reading the only exercise "Heavenly Demon Disintegration".

When he was still the so-called divine favorite, no matter what the cheats, he could learn it with a clap of his hand, and then this exercise would appear in his skill bar, and when he wanted to comprehend, he could call it up and read it as soon as his mind moved.

Now there is no such treatment, he can only put "Heavenly Demon Disintegration" on his crossed legs, flipping through the pages page by page.

The words in "The Disintegration of Heavenly Demons" seem to have some kind of magic, and once Duan Chen reads it carefully, he feels that he is deeply immersed in it and can't extricate himself.

In the secret book "Disintegration of Heavenly Demons", there are a total of nine chapters, and the first chapter is this contemplation chapter.

The contemplation chapter of "Heavenly Demon Disintegration" is somewhat similar to the true dragon and sea chapter in the Heavenly Rank Exercise "True Self Formula", and to some extent, it is used to transform the soul of cultivators.

Duan Chen was a little vigilant in his heart, but then he laughed at himself, what is the use of being vigilant? If you don't practice this "Heavenly Demon Disintegration" because of your vigilance, this "Heavenly Demon Disintegration" will be a pile of useless waste paper!

The cheats on his lap, every time he turned the page, the black leaves of that page would turn into a black mist and dissipate into the sky.

Half a quarter of an hour later, Duan Chen began to meditate, closed his eyes, and began to cultivate according to the description in "Heavenly Demon Disintegration".

The Condensation Chapter is the most basic chapter in "The Disintegration of Heavenly Demons", Duan Chen, as an old monster of the Ten Thousand Things Realm, cultivated very quickly, and in less than 1 minute, a trace of black qi began to permeate his body.

This is the legendary demonic energy, which is an extremely violent and weird energy cultivated by demon cultivators.

These demonic qi are all converted from the energy of creation.

The energy of creation, in essence, is a form of energy existence of formless matter, but after it is transformed into demonic energy, it becomes visible to the naked eye and turns into black qi.

An hour later, Duan Chen's whole body was covered in black ** qi, and he looked like a demon crawling out of hell!

The first article in "The Disintegration of Heavenly Demons" has finally been cultivated.

Next, it's the second part - refining the body!

Unlike normal powerhouses, every demon cultivator's physical body is extremely strong, far surpassing those of the same level.

Duan Chen opened his eyes, his eyes were still clear, and he was not impregnated by that demonic qi.

He continued to carefully read page by page the disintegration of the Heavenly Demon on his lap, but when he turned the page, the page of black paper that he had read would turn into a black mist and dissipate into the air without a sound.

After reading the body refining chapter, Duan Chen closed his eyes and began to transform his body in the mysterious and special way recorded in "Heavenly Demon Disintegration"!

What he didn't notice was that the black mist that had turned into black paper leaves had not really disappeared, but had regrouped together above his head, slowly forming a vague black humanoid silhouette.

The figure figure, floating in mid-air, looked down at him in a condescending manner.

Duan Chen was still practicing with his eyes closed, his skin, in the process of cultivation, gradually became pale, this was a somewhat morbid pale, and even more turbulent demonic qi surged out of his body, filling the space within a radius of several meters!

These demonic qi passed through the body of the humanoid figure, but it did not have any effect on the humanoid figure, and there was even a trace of demonic energy, which was swallowed by the black figure, making the black shadow condense a little.

Duan Chen still didn't notice him, and after sitting for almost 3 hours, the second chapter in "Heavenly Demon Disintegration", the body refining chapter, was also cultivated by him.

Next, what he wants to cultivate is the third chapter in "Heavenly Demon Disintegration" - the soul transformation chapter.

This one is far more complicated than the previous two, and Duan Chen read it for almost 1 hour before he fully understood and comprehended the content of the soul transformation chapter.

The black pages he had flipped through turned into black mist and disappeared into thin air, and the black figure floating above his head became clearer again.

Looking at the outline of this black shadow, it can already be seen that this should be a burly man, the man's face is still very blurry, and he can't see the specific appearance clearly, it is still floating on top of Duan Chen's head, bowing his head slightly, looking down at Duan Chen who is sitting cross-legged below.

The so-called soul transformation is to use an extremely special way to transform the cultivator's soul into all the meridians, internal organs, and limbs of the body, like flowing water.

This has some similarities with the first chapter of the true self that Duan Chen had cultivated, but the difference between the two is even greater, and his soul needs to be transformed at a deeper level.

At the soul level, no matter what kind of transformation is carried out, it is an extremely painful experience, and this kind of soul pain is at least a hundred times more intense than the physical pain.

Therefore, when Duan Chen closed his eyes and cultivated the third chapter of "Heavenly Demon Disintegration", it didn't take long for extremely fine beads of sweat to ooze from his forehead, and less than half an hour later, the sweat soaked through the coarse linen clothes on his body, and his entire face was distorted because of the pain, but with an amazing will, he endured this pain!

He sat cross-legged the whole time, his posture unchanged, his mouth tightly closed, and he did not make any sound.

Above his head, the black figure became a little more condensed, and the outline of his face could already be faintly seen, and it began to absorb the surrounding demonic qi at an accelerated pace.

The black figure was still looking down at Duan Chen, and for the first time, an expression appeared on his face, which was an expression of some surprise.

A faint wave of emotion emanated from the black figure's body.

'What a powerful human being...... What a powerful soul......'

"This human being is too strong, and I'm still too weak to take it away, so let's wait, and when he starts cultivating the 5th or 6th chapter of the Heavenly Demon, the time should be ripe......

'Take advantage of this gap and start summoning the remnants of this world, it will make me stronger......

In the third part of "Heavenly Demon Disintegration", it took Duan Chen 6 hours to complete his cultivation.

Wiping the sweat from his forehead, Duan Chen looked like his whole person had become a little sluggish.

He didn't rush to cultivate the fourth chapter of "Heavenly Demon Disintegration", the doppelganger chapter, but took out one spirit fruit after another from the ring and stuffed it into his mouth.

While chewing the spirit fruit, he thought about something, and his brows furrowed slightly.
