Meanwhile.

In the process of refining the ninth brain domain, the black vortex in the brain domain space was not willing to be lonely.

It began to continuously overflow with black demonic mist, penetrating the entire Ninth Brain Domain to prevent the Ninth Brain Domain from being refined.

In addition, the gene pronucleus has released a heavy sealing chain, sealing the void in trouble, preventing any trace of complex energy from pouring into it, preventing the gene pronucleus from being contaminated.

Under all kinds of imprisonment and defense, the refining process of the Ninth Brain Domain is full of difficulties and challenges.

First of all, facing the brain domain barrier, it is an existence that makes countless martial artists sigh with admiration.

Generally speaking, to be able to break the barrier of the brain domain, at least it is necessary to be an emperor-level powerhouse.

This is why, even ordinary king-sealing powerhouses cannot interfere with other people's brain space.

And even if it is an emperor, he does not dare to easily intervene in the brain space, otherwise it will cause unpredictable disasters.

And at this moment, Lin Fei is acting against the sky!

"I hope the god of war Bai Qi won't pit me! When I finish quenching my ninefold body, that mysterious gift, I hope I don't miss the appointment! ”

Lin Fei did not hesitate to take the risk of trying to refine the Ninth Brain Domain for the sake of a mysterious gift left in the memory of his soul by the God of War Bai Qi.

The tempering of this ninth brain domain is very difficult.

It is not an ordinary way to quench the Tao.

Even if there is a quenching decision, it varies from person to person.

Some people are congenitally weak in the ninth brain domain, and the refining process is relatively easy.

Some people are gifted, and the ninth brain domain is different from ordinary people, and the refining process will be extremely dangerous.

In addition to Lin Fei's talent, the genetic pronucleus suffered an abnormality, coupled with the cloud of magic shrouded in the brain space, which increased the difficulty and risk of refining.

So, when refining the ninth brain domain.

Lin Fei pulled out the Demon Hou and Pu Mo.

"Pu Demon, Demon Hou, you two guys, is there a way to help me temporarily suppress the Demon Cloud, so that I can easily refine the Ninth Brain Domain!"

As soon as they heard that Lin Fei was going to refine the Ninth Brain Domain, these two demons were immediately taken aback.

"Master, think twice! Refining the Ninth Brain Domain, even in ancient times, was taboo, and it would lead to the punishment of the Heavenly Tribulation! Pu Mo said worriedly.

The Demon Marquis scoffed.

"Humph! Rubbish! You know what! In ancient times, when the gods and demons were dominant, the newborn babies of the two races were born with the nine-brain domain completely open, and this kind of thing is not a secret! Later, it was pitted by the human race, so that the descendants born of the gods and demons, including all the races in the universe, became closed in the nine-brain domain! If you want to become the supreme of the universe, the Nine Brain Domain must be fully opened, which the gods and demons have proved in ancient times......"

The Demon Marquis quoted scriptures and ripped out the history of ancient gods and demons.

Obviously, consciousness is to support Lin Fei in refining the ninth brain domain.

Seeing that the Demon Marquis had such an opinion, Lin Fei was overjoyed in his heart.

So he asked.

"Demon Marquis, do you have a way to help me open the Ninth Brain Domain?"

The so-called opening of the Ninth Brain Domain is to completely refine the Ninth Brain Domain and make it into a fully open state.

"No way! However, I have a way to help you suppress the Demon Cloud! ”

"Oh? What's the solution? Lin Fei raised his eyebrows.

The Demon Lord continued.

"It's easy! As long as the master you change the demon body, these demon clouds can be absorbed by your body, so that there is no harm, you must know that my demon clan's body refining method universe is the strongest......"

Let's start again, let's speak for the demons!

Lin Fei was a little interested at first, but he became a little impatient when he heard it.

"Shut up!"

"Huh? Oh, master, don't you think about it? I am the first in the Demon Race Body Refining Universe, and the Protoss is envious! ”

The demon marquis still didn't give up, and continued to recommend it hard.

Lin Fei was a little annoyed when he heard it.

"That's it! The demon race has fallen, if it is really the strongest in the universe, how can it be wiped out? ”

"You ......"

Lin Fei's words made the demon marquis speechless, and his face turned red.

"If you don't refine the demon body, isn't there any other way to suppress the demon cloud?"

Lin Fei continued to ask.

Regarding the origin of this demon cloud, Lin Fei absorbed it from his mother's body, and at the same time, he also obtained the demon marquis.

In the past few years, Lin Fei has already had an in-depth understanding of the Demon Hou, and probably figured out the origin and strength of the Demon Hou.

But the origin of the demon cloud is not well understood.

It's just that I've rarely heard the Demon Marquis call this Demon Cloud the "Demon God's Eye"!

In the past few years, Moyun has been safe in Lin Fei's brain domain, and he has saved Lin Fei several times.

Lin Fei almost forgot about this magic cloud!

And now it is time to temper the brain, and it is the most critical moment.

It is necessary to refine the Ninth Brain Domain, but at this time, the Demon Cloud suddenly jumped out to block it!

On the contrary, it caused Lin Fei's worries!

The previous cultivation was low, and there was nothing to be done about the Demon Cloud!

Now, this magic cloud stays in his head, but it is a time bomb!

It's hard to sleep!

"Just take advantage of this time to temper my brain, I have to find a way to take this demon cloud out of my head!"

Lin Fei thought in his heart!

But time waits for no one!

At this time, the star energy in the body was full, as if it was about to break through the shackles of the dantian, directly break through the bottleneck, and forcibly break through the realm.

It's like a pressure cooker that is about to explode, and it's about to reach a critical value.

And at this time, refining the ninth brain domain, there are three mountains in front of him, which cannot be crossed for the time being.

"What should I do?"

At that moment, Lin Fei deeply felt a sense of helplessness.

"That's it! Fight for it! I have an evolution pool, and even serious injuries can be repaired! ”

"Time is running out! Spelled ......"

Lin Fei didn't care about anything else at the moment, so he had to rush forward.

The ninth level of the quenching body has been practiced to the eighth turn, and the last turn will be able to reach the Great Perfection.

Randomly, Lin Fei manipulated the three major energies to frantically sprint to the ninth brain domain.

At that moment, the power of the bloodline, as the vanguard, directly sprinted to the brain domain barrier.

but was defeated.

Then, the Yin and Yang True Thunder rose to the challenge, and the power of the thunder was unbreakable, just restraining the brain domain barrier.

After the brain domain barrier lasted for a while, it was broken through by the Yin and Yang True Thunder.

Then, the soul energy formed a soul barrier to expand the gap that broke through, and then the power of the Yin and Yang True Thunder and the bloodline continued to pour into the Ninth Brain Domain.

During this process, a huge amount of energy suddenly broke into the Ninth Brain Domain, causing the space in the Ninth Brain Domain to be disordered, and then the Demon Cloud moved, releasing a large amount of black energy to block the power of Lin Fei's bloodline and the Yin and Yang True Thunder to break in......

Unexpectedly, the moment the black energy touched the Yin and Yang True Thunder, it disappeared one after another as if it had met a nemesis.

Demon Cloud even had a hint of timidity.

In this process, even the Demon Marquis and Pu Demon were afraid.

"Master, quickly restrain the Yin and Yang True Thunder, otherwise the Demon Cloud will run wild, and it will be out of control! Even we are doomed! ”

"Yes! Master, we are all just remnants now, and we are most afraid of the power of thunder, if the master is not careful, we will be scattered! ”

Demon Hou and Pu Demon felt the Yin Yang True Thunder, and they both showed fear, and they all asked Lin Fei to put away the Yin Yang True Thunder.

But at this moment, Lin Fei is difficult to ride a tiger, and he will pay attention to it there.
