First of all, even if the peripheral meridians are opened up and the internal breath is operated inside, it will not be significantly strengthened because of the weakness of the peripheral meridians themselves.

If you have that spare time, it is better to let the internal breath run in the other meridians for a week.

Secondly, even if you are really so idle, even so idle that you want to open up the peripheral meridians, but the number of peripheral meridians in the normal human body is as high as millions, and if you want to open them one by one, it is an extremely terrifying workload, and you can't complete it until you die.

There is not enough gain, and it will take almost unlimited hours of terror, so naturally no warrior will waste his efforts on this.

As far as Chu Nan knows, all the internal breath exercises are actually the same as the Nine Turns of the Heart Method, choose an internal breath trajectory that can affect the whole body, and then open up the main meridians and secondary meridians required by this internal breath trajectory, so as to achieve the desired effect of refining the physical body and improving the strength of the internal breath.

According to the different internal breathing exercises, each martial artist's own meridian conditions are different, and the cultivation effect is different.

But no matter what, no internal breath technique will try to open up all the main and secondary meridians, and no martial artist will do it, because it is completely thankless.

And opening up the peripheral meridians is something that you don't have to think about, unless this martial artist is really crazy.

Of course, Chu Nan was not crazy.

The biggest problem encountered by other martial artists is that it takes a lot of time to cultivate by opening up the meridians and refining them, so they must choose the internal breath exercises and cultivation methods that are most suitable for themselves and can improve themselves the most, so as to improve themselves at the fastest speed.

However, Chu Nan's current situation made it impossible for him to improve himself in the normal way, otherwise he would not have time to complete the tempering of the hegemonic body before the flesh * body was completely formed, and it would become almost impossible to break through the Heavenly Pass of the Universe in the future.

And more importantly, Chu Nan has a powerful data ability like a light brain, and with this ability, he now has far less time to open a meridian and refine it than a normal martial artist.

He can even rely on his powerful data capabilities to perform multi-threaded operations at the same time, and open dozens of meridians in one go.

Therefore, after opening up the remaining primary and secondary meridians, Chu Nan did not hesitate to turn his target to the peripheral meridians.

However, he miscalculated.

Chu Nan originally thought that the peripheral meridians were countless times smaller than the main meridians and secondary meridians, so the strength of the internal breath required to open them up must be much lower, so he simply divided a wisp of internal breath into a full hundred strands in one go, and at the same time poured into a hundred different peripheral meridians throughout the body, intending to open them all at once.

Unexpectedly, he still overestimated these peripheral meridians.

When he divided into a hundred paths, the internal breath that was obviously so weak that it was almost unspeakable poured into these peripheral meridians, and in an instant, it almost completely overwhelmed these peripheral meridians, so that his whole body was oozing blood, and in the blink of an eye, he became a bloody person.

Fortunately, the impact of the peripheral meridians on the body is too weak, and for the sake of insurance, the peripheral meridians he chose are distributed in different locations throughout the body, which will not have a chain effect, but there is no major problem except for the pain like pins and needles felt throughout the body.

Chu Nan didn't bother to clean up the blood on his body, so he thought about it for a while, and there was an unusually weak trace of internal breath everywhere from the dantian, and then he carefully probed in front of a peripheral meridian that was connected to the secondary meridians.

This time, he first controlled this faint inner breath and tested it at the entrance of the peripheral meridian.

A pinprick of pain rose again, making Chu Nan sure that this trace of internal breath was still too strong for this peripheral meridian.

Then he pulled out a much weaker trace of internal breath from the dantian.

After more than ten times of repeated experiments, Chu Nan adjusted the internal breath to a strength that was at least ten times weaker than at the beginning, and finally succeeded in rushing into the peripheral meridian without causing any abnormality, only feeling an extremely faint feeling of swelling brought by the meridian.

This feeling is the feeling that the meridians are being dredged, and Chu Nan is already very familiar with it.

After carefully controlling this incomparably faint trace of internal breath through this peripheral meridian, Chu Nan breathed a sigh of relief.

Facts have proved that the peripheral meridians, like the main meridians and secondary meridians, can also be opened, but because they are too weak and fragile, they need to be more careful.

Next, Chu Nan tested a few peripheral meridians in other places, and successfully tested that the difference between the peripheral meridians is actually quite large, and the strength of the internal breath suitable for opening them up can be as large as dozens of times.

This discovery made Chu Nan feel a little tricky.

The peripheral meridians have a terrifying million in the body, and if such a test continues, it will really be impossible for him to get them all when he dies of old age.

"So at the end of the day, you can't use the normal method."

Chu Nan sighed, then calmed down, concentrated all his energy, and a wisp of internal breath was transferred out of the dantian, and it was instantly divided into two hundred extremely weak internal breaths, which flowed into two hundred different peripheral meridians.

Due to the previous test experience, there are only thirteen peripheral meridians that cannot be withstood this time, and all the rest have allowed the internal breath to pass smoothly, and even some peripheral meridians are relatively strong, and there is no reaction at all after the internal breath flows.

Chu Nan condensed again, and another wisp of internal breath was transferred out of the dantian, and it was instantly divided into an even more exaggerated four hundred internal breaths.

Among them, 200 internal breaths flowed into the 200 peripheral meridians that had been tested before, and thirteen internal breaths were adjusted to a high-frequency vibration state by it, and began to repair the peripheral meridians that had been damaged just now, and the other 187 internal rules had different intensities, and they entered the corresponding 187 peripheral meridians, just so that the 187 peripheral meridians were slightly damaged but not too much.

Through the data collected before, to determine the accurate data of the intensity of the internal breath required to open the meridians, and then adjust the right amount of internal breath to impact the meridians, this is the standard practice of Chu Nan to open the meridians now.

As for the other two hundred internal breaths, they rushed into the other two hundred peripheral meridians, and the process just now was repeated in these two hundred peripheral meridians.

So while conducting data tests, repairing and dredging, while constantly refining the peripheral meridians that had been opened before, in the back, Chu Nan actually separated and maintained a full thousand internal breaths in his body at the same time, and at the same time opened up and destroyed and repaired a thousand peripheral meridians.

With so many internal breaths of different intensities and even different vibration frequencies flowing in the meridians at the same time, it was impossible for any martial artist to control them, but Chu Nan could control them accurately, and he could also play a corresponding role on thousands of peripheral meridians with the same precision.

This is equivalent to the BUG-like ability that the data ability of the light brain brings to Chu Nan. (To be continued.) )
