"Huh? Is it that simple? ”

"If I'm not mistaken, it should be that simple!" The Demon Marquis said with an oath.

Just kidding, he rushed to the Dark Demon Codex, one of the three major treasures of the Demon Clan, and the Demon Marquis didn't dare to say anything.

So, according to what the Demon Marquis said, Lin Fei tried to touch a nearby ball of light with his soul sense.

Sure enough!

The moment the soul sensing touched the ball of light, a stream of soul information quickly drilled into Lin Fei's mind.

"Sword Forging"

"Oh? It turned out to be a secret book for casting all kinds of swords! Unfortunately, for me now, it's not urgently needed! ”

Lin Fei's mind moved, and then he swept his soul thoughts towards the other balls of light.

"Rune Explanation, useless!"

"Ancient History Research, useless!"

"On the History of the Rise and Fall of the Dragon Clan, useless!"

……

LIN FEI'S SOUL THOUGHT SWEPT OVER THE VARIOUS LIGHT BALLS ONE BY ONE, AND ALL USELESS LIGHT BALLS WOULD BE DIRECTLY PASSED BY LIN FEI.

Rao is like this, the vast ball of light here is like a sea of stars, and there is no end in sight.

As a result, Lin Fei began to try to differentiate thousands of soul thoughts, and at the same time divide thousands of soul thoughts to scan light balls.

This speed is instantly increased.

In addition, Lin Fei's soul mind is strong and has the assistance of the cosmic brain, so he can basically remember the position, coordinates, and book content of each scanned light ball.

Hard work pays off.

An hour later.

Lin Fei was the first to find a cultivation notebook, which was some notes on the cultivation of a disciple of a sect in ancient times.

It is called "Tiangang Quenching Body".

This disciple's name is Ren Tiangang, so he is named so.

When he was less than twenty years old, he had already cultivated the Nine Folds of Quenching the Body to the Perfection Realm.

Then, with his physical cultivation, he can hard-shake the legendary powerhouse.

became a starry sky at that time, a genius boy with a far-reaching reputation.

Later, Ren Tiangang relied on the quenching body to make his own improvements, and proposed to temper the physical body with the ubiquitous gang wind in the universe, so he wrote down the tenth exercise method after the quenching body decision.

It is the so-called "Tiangang Quenching Body"

And this "Tiangang Quenching Body" is divided into three realms: Xiaocheng, Dacheng, and Consummation, and after the cultivation is completed, the power of the physical body can even be comparable to that of the emperor.

It's hard to imagine.

However, this Tiangang's experience in cultivating and quenching the body has given Lin Fei a lot of benefits.

"It turns out that the ninth level of cultivation is the quenching body, the younger you are, the easier it is! It is best to complete it in the mother's womb, which is called congenital quenching! ”

"It's a pity that since the human race was born, all natural functions have begun to decline rapidly! If you want to return to the innate body in the mother's womb, it is even more difficult! ”

"I remember that the Qinglan Sect has a special practice for cultivating the innate fetal breath called the "Heavenly Fetal Breath Technique", in order to absorb the power of the stars to return to the true nature and achieve the innate body state in the baby's mother's womb! In this state, it will help you to achieve enlightenment! But I didn't expect that it is also good for refining the brain! ”

Immediately, Lin Fei quickly memorized this exercise.

Lin Fei didn't have kung fu cultivation now, so he had to wait for the follow-up to be free before trying to make a breakthrough in cultivation.

And at this moment, all the attention from Lin Fei was focused on finding other exercise books.

After a short time, Lin Fei collected more information about the Holy Domain.

At this time, Lin Fei only needed to find the books and documents that recorded the Holy Domain, and then use the soul energy as the traction to import all these materials and information into the brain and store them.

Subsequently, there were also a large number of soul cultivation exercises and experiences, which were also collected by Lin Fei in one go.

In just three days, all the three types of books that Lin Fei urgently needed were collected.

After that, Lin Fei was not greedy and began to cultivate.

"This underground vault is so hidden that you can't enter it without a key! I'm just here to cultivate! ”

As a result, Lin Fei entered the evolutionary space.

This time after entering the evolutionary space.

The first thing Lin Fei did was to start following the guidance of the cultivation exercises of "Tiangang Quenching Body", and cultivating the ninth level of quenching the body.

This time, when Lin Fei was cultivating the Quenching Body, he began to cultivate the Heavenly Birth Breath Technique in advance.

After a short time, Lin Fei's breathing stopped and he entered a congenital fetal breath state.

In this process, Lin Fei entered the state of Bigu.

There is no need to eat, drink, drink and breathe, and the body forms a closed small universe, which can maintain the normal operation of the body's cells just by relying on the innate fetal breath and absorbing star energy.

Of course, this congenital state of fetal breath cannot last long.

With Lin Fei's current physique and ability, he can only last for three days at a time.

As soon as the three-day period is up, the congenital fetal breath state will be automatically lifted.

It was seen that in the state of congenital fetal breath, Lin Fei's five senses were automatically closed.

In this state, the soul sense is more active and clear.

Although I closed my eyes, the world I saw in my soul was clearer.

It is even possible to directly observe the particles of the microcosm and see the starlight particles directly......

The blood vessels, meridians, and bones and organs in the body all became extremely clear under the observation of the soul.

"Huh? This state is very similar to the soul cultivation state I entered the "Cosmic Brain Visualization" before, although I have not cultivated the soul technique, but I feel that the soul energy is rapidly improving! ”

Lin Fei experienced the benefits of congenital fetal breath.

I was taken aback.

At the same time, after Lin Fei was fully prepared, he began to cultivate the ninth level of quenching the body.

This time, when the exercises were working, Lin Fei noticed the difference.

I feel that in the congenital state of fetal breath, the operation of the quenching body is more mellow and smooth, and all obstacles are eliminated.

Comprehend, in the state of congenital fetal breath, the Yin and Yang True Thunder is manipulated by the soul more easily.

It's like breathing and drinking water.

In this process, refining brain cells is like opening a hanging.

It's only a quarter of an hour.

The sixth turn of the ninth and sixth rounds of the quenching duel is completed.

Airplanes......

At that moment, the brain cells completed the sixth star energy penetration, and the entire brain circuit could be tempered through star energy.

This sixth turn is a watershed moment.

After that, the process of quenching the brain can directly replace the bloodline energy with star energy.

Star energy is more violent, but the energy is inexhaustible, and the more violent, the effect of refining is naturally better.

However, due to the special structure of the brain and the fragility of brain cells, it is not able to withstand too strong and violent star energy.

And after completing the six turns after the bloodline energy and yin and yang true thunder quenching, Lin Fei's brain cells already had the endurance to withstand the star energy quenching body.

Immediately, there was an infusion of star energy.

Lin Fei's brain cell refining speed accelerated again.

At this time, blood vein energy, yin and yang true thunder and star energy, the three energies were mixed and poured into the brain cells at the same time.

Not only will it not cause trouble due to the chaos of energy, but it is the cooperation between the three energies, each giving full play to its own strengths, thus greatly improving the efficiency of refining the brain.

After three days, the brain has been tempered for seven turns.

At this time, Lin Fei's head was like a light bulb, and after being shrouded in endless star energy, it released a dazzling light.
