I don't know how Dunleavy talked to yonotag. In short, just three hours later, Chunan and Alvey had sat on the space flight to the earth together.

"Good night, brother Chu Nan."

Ivy showed a sweet smile to Chunan, waved her hand and returned to her box.

Seeing her figure disappear behind the door, Chu Nan smiled and shook his head.

After this incident, Ivy obviously became more lively in front of him and felt much closer.

This experience seemed to shorten the distance between them all at once.

However, every time alvie smiled and called him "brother Chunan", Chunan still felt uncomfortable.

In the final analysis, although ivy is only 14 years old, more than four years younger than him, she is not like Trina, but an 11-year-old girl who always feels strange to shout her brother so sweetly.

"Forget it. Anyway, when she gets to Xingyun college, she goes to the College of life sciences, and I go to Wuzhe college. There shouldn't be too many opportunities to meet in the future. Just follow her."

Chu Nan shrugged and turned back to the box.

The journey from Aucma to the earth will take more than a day. In this day, he doesn't want to waste it completely. He just takes advantage of this time to continue to study the sixth weight of the nine turn mind method.

Although he had successfully completed the nine turns of internal breathing before, and showed extremely powerful power in the battle. He just smashed an enemy with three levels of internal breathing strength into pieces with one punch, it doesn't mean that he really succeeded in cultivating the sixth level of nine turns mental skill.

According to the records left by Su Xuansheng at the beginning, if the sixth level of cultivation is successful, the internal breathing will be perfectly integrated with spatial energy and mobilized at will.

In fact, this realm is almost the same as that after breaking through the cosmic pass, but there are some subtle differences.

There is no detailed explanation in the secret collection of jiuzhuan mental skill left by Su Xuansheng. Chu Nan can only practice and study it by himself.

He sat on the bed again, quickly mobilized the internal breathing, and soon completed the nine turns of internal breathing again.

Compared with the first experiment, his internal breathing nine turns are now quite stable.

Feeling the influence of space energy and internal breathing, Chu Nan kept entering the body from the outside and then flowing out of the body, forming a complete circulation around the body. Chu Nan thought of a problem.

The reason why he can feel, attract and even control space energy when the internal breathing intensity is at the second-order internal breathing level is entirely due to the special high-frequency vibration internal breathing.

After introducing space energy into the body, when the internal breathing flows in the meridians, in fact, he did not deliberately control the internal breathing to a high-frequency vibration state.

However, even so, the spatial energy entering the body will still be obedient, integrate into the internal breathing and flow normally in the body of Chu Nan.

And when this part of space energy leaves the body, even if there is no need to use high-frequency vibration breath, it will still be controlled by Chu Nan within a certain range.

Since this is the case, it means that space energy does not have to be controlled with high-frequency vibration breath.

On second thought, Chu Nan found that this was nonsense.

Apart from him, it can be said that there is no second martial artist in the world who can maintain the internal breathing in a high-frequency vibration state and accurately control the vibration frequency.

However, in addition to him, there are countless warriors who can break through the cosmic pass and easily control space energy.

In the final analysis, the control of space energy has nothing to do with the high-frequency vibration internal breathing. It only needs the martial artist's internal breathing practice to a certain extent, then he can feel the space energy and use the internal breathing to guide.

Those who can integrate internal breathing perfectly with space energy can break through the pass of the universe and become air breaking warriors. This is the common sense that all warriors understand.

"So... Can I move the integration of internal breathing in the body and spatial energy out of the body?"

Chu Nan thought for a moment and began to continuously mobilize space energy again, maintain the circulation of space energy in the body, and carefully "observe" the integration of space energy and internal breathing.

This is the first time Chu Nan has done so.

Previously, although he has integrated space energy and can skillfully control it, he has just been following the trend and has not seriously studied what's going on.

Now after such a serious "observation", Chu Nan immediately found that although spatial energy is integrated with internal breathing in the body and then flows in the meridians and flesh * body together, there are some slight differences in the fusion situation in different meridians and even in different flesh * body parts, which can be called the degree of fusion.

If you are an ordinary warrior, you certainly won't care about this difference.

However, Chu Nan has strong data capability. Of course, he is very sensitive to this difference and is very curious about why this difference occurs.

He "observed" for a while, and soon recorded the energy flow of each internal breathing fusion space.

However, he found that the reason for this difference is that there are some differences in the circulation of internal breathing in different meridians and in different parts of the body.

This difference is reflected in intensity and, most importantly, in frequency.

If Chu Nan doesn't deliberately control it, the circulation of internal breathing in the body will naturally change according to the different physical meridians.

This is a very normal and easy to understand phenomenon.

But Chu Nan didn't intend to let it go.

He continued to "observe" for a while. He could adjust the vibration frequency of internal breathing in some meridians. Then he found that the integration degree of internal breathing and spatial energy also changed.

After repeated testing for hundreds of times, Chu Nan found that not every place maintains the same internal breathing vibration frequency and intensity, which will keep the integration degree of internal breathing and spatial energy the same.

There are still differences according to the specific conditions of meat * body meridians.

So Chu Nan tested it a hundred times again and found that it was not necessary to keep breathing. The higher the vibration frequency, the higher the degree of fusion.

It is to maintain the most appropriate internal breathing in different parts to maintain the highest degree of integration.

If you are an ordinary warrior, of course, you can't surprise and even control the internal breathing. But for Chu Nan, it's no problem.

I feel that after 36 more tests of the inference just now, Chu Nan determines the next complete internal breathing operation model, and then moves his mind. The internal breathing runs perfectly according to this model.

Soon, space energy entered the body. As expected, Chu Nan maintained the highest degree of integration in all places.

When the space energy completely circulates in the body again, Chu Nan suddenly found that his body suddenly seems to open up more space, and part of the space energy naturally circulates in the body.

Although this part of space energy is very weak, and the circulating channel "looks" fragile, it is closely related to the external space energy.

There is no need for Chu nan to deliberately use high-frequency vibration breath to guide, and the external space energy will automatically flow into Chu Nan's body.

Chu Nan was shocked to see the changes in his body.

"Shit, I won't inadvertently break through the pass of the universe!" (to be continued)
