As soon as the Nether Source entered the body, the cold breath permeated Gu Chen's body, limbs and bones.

It's just that before this original power had time to transform Gu Chen's body, it was attracted by the black hole in the dantian and burrowed into it.

Gu Chen felt as if he was facing a formidable enemy, and deliberately slowed down the speed at which the Nether Origin escaped into his dantian to avoid any accidents.

At this moment, his dantian looks like a black hole from the outside, but inside the black hole, there is a hole in the sky.

The branches of the mother root of all things linger in the chaotic air, still standing in the center of this strange world.

The golden light group representing the hegemony body and the nine-color light group of Gu Chen Xianzun's later cultivation are like stars all over the sky, shining around the mother root of all things.

In addition, the space inside the black hole is almost completely occupied by a round of emerald green sun, which is the source of life.

It was suppressed in this black hole, and the brilliance of the light it possessed was far better than the golden light group and the nine-color light group.

At this moment, the dark source of the netherworld slowly enters the black hole, and just a ray of cold breath enters, making this space seem to be boiling.

The entire dantian began to roar violently, and the speed of the rotating black hole suddenly slowed down!

Realizing this scene, Gu Chen's heart sank.

Sure enough, after absorbing the source of life, the black hole in Dantian has reached its limit, and it is difficult to accommodate the source of ghosts!

Even this limit is lower than he imagined. He originally planned that if he could accommodate part of the source of the nether world, it doesn't matter if the rest is wasted.

This is the worst situation, Gu Chen can only find another place for the origin of the nether world.

"It seems that we can only try to open up a quadrupole black hole."

Gu Chen muttered to himself, and set his gaze on his right hand.

The black hole volume is divided into five realms, corresponding to the five secret arts, and also corresponding to the five major structures of the human body, namely the dantian, quadrupole, dragon bone, blood and Niwan Palace.

Through the cultivation of secret techniques, a small black hole can be opened in the corresponding body structure.

And when the black holes of the five major structures are all formed and merged into one, the black hole scroll can be considered as a complete cultivation.

At that time, it is said that the body can be turned into a real black hole, easily devouring the stars and stars in the place it passes, and reaching a state of extreme power unimaginable by human beings...

Gu Chen, the sixth layer of the secret technique of star core cracking, has successfully cultivated, and the first black hole in the dantian was successfully opened.

The next second black hole is located at the four poles of the human body, where the limbs are.

If you want to successfully open up a quadrupole black hole, you need to have completed the seventh heavenly secret technique, quadrupole collapse.

Gu Chen just opened up the first black hole not long ago, and now he will try to open up the second one in a short time, which can be said to be extremely risky.

But right now he has no choice, the dantian black hole can no longer contain the source of the nether world, the only feasible way is to continue to open up new black holes.

Only the special existence of the black hole in his body can successfully seal the original power, so that they will not be lost, nor will it cause him to break through into the emperor's realm.

Asking about one realm, when a monk condenses his origin, his physical body, soul and other aspects will be sublimated to the utmost, so that he can have the power of an emperor.

Gu Chen once saw the man in the hat break through with his own eyes, and he knew that the stronger the original source he had when he broke through, the stronger his strength would be after stepping into the Taoist realm.

Just the source of the soul can make the man in the bamboo hat so strong, what if he has multiple sources at the same time?

This is the train of thought of Gu Chen's way of cultivation. He wants to suppress his cultivation as much as possible, gather more origins, accumulate a lot of knowledge, and see what will happen at that time.

However, how powerful the original power is, how easy is it for ordinary people to forcibly suppress the realm?

Not to mention suppressing multiple sources, even suppressing one is very difficult.

Gu Chen has unique conditions because of practicing Tianchen Wanxiang Jue and the three secret methods, and has the possibility of challenging this path.

But those are just assumptions, it is an imperfect road, and he needs to keep trying and comprehending on the way forward. If he takes a wrong step, he may end up in ashes.

At this moment, he came to the fork in this road again!

"According to the current situation, every time we absorb an origin, we need to open up a black hole. If the progress of mystic practice cannot keep up with the speed of absorbing the origin, then this road will mean failure."

"Fortunately, the five levels of secret arts involved in the black hole volume are surprisingly similar. Although the risk is high, they are not like the previous five levels of secret arts, which require years of comprehension."

Gu Chen closed his eyes, and the cultivation content of the seventh heavenly secret technique, Siji Beng, emerged in his mind.

The cultivation methods of the five levels of secret arts involved in the star dust volume and the star core volume are often very different. The sun and moon refining is to absorb the essence of the sun and the moon, and the heavenly vibration is to comprehend the law of gravity.

In addition to extremely high talent, cultivating the five-level secret technique often requires a special astronomical environment. Its various restrictions doom it to take a long time to practice.

As for the five levels of secret arts involved in the black hole scroll, the degree of danger is not lower than the previous five levels, because every failure is either disability or death, and there is almost no turning back.

But this five-layer also has an advantage. The core content of its cultivation is to open up black holes, so it is surprisingly similar in many aspects.

It took Gu Chen two years to comprehend the secret art of splitting the star core, which was actually of great help to the last four secret arts.

At this moment, in order to absorb the source of the nether world, he must open another black hole. It seems reckless, but it is not impossible.

"open!"

Gu Chen raised his right hand, mobilized the power in his body according to the content of the secret technique, and poured it into the palm of his right hand.

For a moment, his entire right arm was filled with thunder and lightning, and mysterious changes took place in the flesh and blood cells!

During this process, Gu Chen was extremely cautious, not daring to take it lightly.

Although quadrupole collapsing and star core splitting mystic technique are essentially opening up black holes, there are some differences, the most obvious being that quadrupoles have to be opened up in four places.

Only when the four poles are opened to form a cycle is it a complete black hole, and the seventh heavenly secret technique is considered a great achievement.

Gu Chen doesn't expect to penetrate all four poles in one go, but only hopes to open up the black hole on the right hand first.

Long——

At the initial operation of the secret technique, the skin of Gu Chen's right arm was burnt red, and after a while it was completely burnt away, revealing the golden flesh and veins.

Seeing this, Gu Chen's face changed slightly, but he continued to operate the secret technique calmly.

The worst result of practicing the Quadrupole Collapsing Secret Art is that this arm will be abolished.

And because the secret technique consumes a lot of vitality, once it is abolished and you want to rebirth with a broken arm, you have to pay a huge price.

Gu Chen no longer has an immortal body, this situation is even more unfavorable for him, he may become a one-armed person at any time.

But he didn't think so much, and continued to use the secret technique without fear.

bang bang bang!

Suddenly, the flesh and blood on the surface of the right arm began to explode one after another, blasting out a cloud of blood mist, and even the bones inside seemed to be broken!

Gu Chen gritted his teeth, but he was unwilling to stop.

If the secret technique cannot be completed, God can take this arm away if he wants to!

He insisted on going his own way, and continued to use the secret technique. His whole arm gradually couldn't bear the power of the secret technique, and it seemed that it was about to shatter.
