Seeing that Chu Xiaoxi didn't even use chopsticks, grabbed a piece of oversized meat and stuffed it into his mouth, looking like a starving ghost reincarnated, Chu Nan couldn't help laughing. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Although using high-frequency vibration internal breath to cooperate with the flame of life can quickly help Chu Xiaoxi repair her damaged meridians, it requires a lot of life force.

Unlike Chu Nan at the beginning, the current Chu Xiaoxi's internal breath is not strong enough, her body is not tempered enough, and her vitality is far less strong than Chu Nan at the beginning, so the process of opening up and refining the meridians with the help of Chu Nan just now has greatly consumed her vitality, and her body needs the same amount of replenishment.

Hunger is the most obvious manifestation of this.

"Eat slowly, don't choke." Chu Nan handed Chu Xiaoxi a glass of water, looked at her munching on the desk, frowned slightly, and pondered.

Through an afternoon of forcibly opening up and refining, all of Chu Xiaoxi's current main meridians and secondary meridians have been strengthened, and they are now enough to withstand Chu Nan's three internal breaths.

This means that until Chu Xiaoxi cultivates to the fourth level of the Nine Turns Heart Method, she will not be limited by the refining of the meridians, so that she will improve extremely quickly in the cultivation of internal breath.

Even because the meridians have been completely opened, she doesn't need to be like Chu Nan and other martial artists who cultivate the Nine Turns of the Heart Method, she can only start from the first Nine Turns of the Heart Method, one by one, and cultivate step by step, but can directly start cultivating from the fifth level of the Nine Turns Heart Method.

At the same time, Chu Nan also specially adjusted and modified the fifth level of the Nine Turns Heart Method according to the data in her body according to the detailed data of the various meridians collected from her, making it more suitable for the meridian conditions in Chu Xiaoxi's body.

In this way, Chu Xiaoxi's starting point for cultivating the internal breath exercise method has far exceeded Chu Nan's beginning, and the improvement speed in the future will be even more exaggerated.

Just now, she was only trying to run the fifth level of the Nine Turns of the Heart Method for the first time, and the increase in internal breath was already very impressive, and it had increased by more than 1% in just one week.

This data doesn't seem like much, but if you continue to cultivate like this, your internal breath will improve faster and faster in the future.

Chu Nan believed that in less than half a year, Chu Xiaoxi should be able to cultivate to the third level of the Nine Transformations Mind Method, which was enough to be comparable to the internal breath strength of ordinary fourth-order or even fifth-order hegemon-level martial artists.

But there was another problem that Chu Nan couldn't determine.

There is no need to doubt Chu Xiaoxi's internal breath improvement speed, but can her flesh * body refining level also keep up?

No matter how strong the internal breath is, it takes time to refine the flesh and body.

After all, Chu Xiaoxi's cultivation of martial arts has not been long, can her physical * body be tempered to a sufficient extent before the age of 18 to avoid encountering obstacles when breaking through the Heavenly Gate of the Universe in the future?

In the final analysis, what are the specific requirements of the Zhou Yu Tianguan for the flesh * body?

When Chu Nan asked Venerable Auvili about this question before, the answer he got was that this requirement was different for each martial artist.

Because different martial artists have different degrees of physical tempering, the exercises they practice are also different, and their comprehension of spatial energy is still different, so when it comes to breaking through the Heavenly Pass, each martial artist faces a completely different situation, and there is no way to give a very standard quantitative value.

If you have to talk about it, as long as the physical body can withstand a strong enough spatial energy and successfully generate an inner small universe, then it means that the strength of the physical body is enough.

This made Chu Nan very puzzled.

Mu Yutong and Normanli, the two star-level martial artists, both judged that he would almost not be able to break through the Heavenly Gate in the future, based on the fact that his flesh and body were not refined enough.

He didn't doubt the judgment of the two powerful star-level martial artists, but compared to more than half a year ago, his current physical * body had undoubtedly improved significantly in all aspects, so was it still not enough to meet the requirements of breaking through the Heavenly Realm?

Or is his physical strength actually enough?

Chu Nan wasn't sure, so he decided to give it a try.

There is another very important reason why he made this decision, that is, he has now cultivated the fifth level of the Nine Transformations Mind Method to perfection with his powerful data ability, and it is difficult to improve simply through the exercises.

Moreover, in the previous assessment, he inadvertently comprehended the special technique of using high-frequency vibration internal breath to attract spatial energy and cooperate with the cultivation of the Nine Turns Mind Method, so that his current internal breath has actually basically reached the level of breaking through the fifth level of the Nine Turns Mind Method.

If he continued to cultivate, he would indeed be able to continue to improve his internal breath strength, but he would no longer be able to obtain the essential improvement.

To put it simply, if you want to improve, you must try to break through the Fifth and Ninth Mind Turning Method.

According to the exercise materials left by Su Xuansheng back then, the sixth level of the Nine Turns Mind Method has already involved the mastery and use of space energy, and also left a part of the information about cultivating the Nine Turns Mind Method to break through the Heavenly Gate of the Universe.

There is not much content in this information, but he has made a very vague explanation by using his own inner small universe with the Nine Turns of Mind Method, without any specific introduction to the exercises.

But for Chu Nan, this is enough.

With his mind already decided, Chu Nan looked left and right, left the house, came to the open space outside, and sat cross-legged.

He first mobilizes the internal breath to form a high-frequency vibration state on the surface of the body.

Soon, the familiar spatial energy had already surrounded him, and after being attracted by his high-frequency vibrational inner breath, he was brought into his body by the inner breath and penetrated deep into the meridians.

This time, Chu Nan did not just let the spatial energy flow with his internal breath as before, but consciously manipulated it, allowing these spatial energies to form a special circulation in the meridians in his body.

At first, he controlled the spatial energy according to the method that Angel Belle had taught him to simulate the generation of an inner small universe.

After experimenting like this a few more times, Chu Nan began to get used to the existence of spatial energy in his body, and then recalled in his mind Su Xuansheng's description of the sixth level of the Nine Turns of the Heart Method.

After a while, he controlled the internal breath to form a second rotation, and then controlled these internal breaths to penetrate out of the body again, in a high-frequency vibration state.

The high-frequency internal breath that had become significantly stronger instantly attracted the significantly stronger spatial energy, and then was brought into the meridians in the body.

Chu Nan's body trembled slightly.

When these obviously powerful spatial energies poured into his body, he immediately felt that something seemed to be something strange in his body.

It's not uncomfortable, it's just a feeling...... It's not that smooth.

Chu Nan controlled the second turn of the inner breath to guide these much more powerful spatial energy to circulate in the body for a few weeks, recorded these strange data one by one, and then raised the internal breath again to the third turn.

The more powerful spatial energy entered Chu Nan's body meridians along with the more powerful high-frequency vibrational internal breath, and he immediately felt that the strangeness he felt just now was even more obvious, and at the same time, there were more places to feel the abnormality.

After repeating for a few weeks and accurately recording these data, Chu Nan continued to improve his internal breath, and soon formed four turns, and then five turns......

With Chu Nan's current internal breath strength, when his internal breath turns five times, it is already enough to be compared to a fifth-order internal breath-level martial artist.

But when the five-turn high-frequency vibration internal breath entered his body with the same powerful spatial energy, Chu Nan immediately felt as if his body was under infinite pressure.

In just an instant, more than half of the meridians of his whole body were damaged, large areas of muscles were directly torn, and even muscle cells were directly necrotic, and at the same time, there was a crisp sound of "click" up and down his body.

In just the blink of an eye, more than a dozen bones were directly broken! (To be continued.) )
