First of all, even if you open up the peripheral meridians and let the internal breathing run inside, you will not be significantly enhanced because of the weakness of the peripheral meridians themselves.

With that spare time, it's better to let the internal breathing circulate in other meridians for a week.

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

There is not enough income, but also spend almost unlimited terrorist time. Naturally, no warrior will waste his efforts on it.

All the internal breathing skills known to Chu Nan are actually the same as the nine turn mind method. Choose an internal breathing movement track that can affect the whole body, and then get through the main and secondary meridians required by this internal breathing movement track, so as to achieve the desired effect of quenching the body and increasing the intensity of internal breathing.

According to different internal breathing skills, each martial artist's own meridians have different cultivation effects.

But no matter what, no internal breathing skill will try to get through all the main and secondary meridians, and no martial artist will do so, because it is completely thankless.

And getting through the peripheral meridians is something you don't even have to think about, unless the martial artist is really crazy.

Chunan is certainly not crazy.

The biggest problem encountered by other martial arts practitioners is that it takes a lot of time to open up the meridians and harden them. Therefore, they must choose the internal breathing skill and cultivation method that is most suitable for themselves and can improve themselves, so as to improve themselves at the fastest speed.

However, the current situation of Chu Nan makes it impossible for him to improve himself according to the normal way, otherwise he will have no time to complete the body quenching before the meat * body is completely shaped, and it will be almost impossible to break through the cosmic pass in the future.

Moreover, more importantly, Chu Nan has the powerful data ability of light brain. With this ability, he can open a meridian and quench it for far less time than normal martial artists.

Even with its powerful data capability, it can conduct multi-threaded operation at the same time and open dozens of meridians at one go.

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

However, he made a miscalculation.

Chu Nan thought that the peripheral meridians were countless times smaller than the main meridians and secondary meridians, so the intensity of internal breathing needed to get through them must be much lower, so he simply divided a wisp of internal breathing into 100 tracks at one time, and poured into 100 different peripheral meridians all over the body at the same time.

But unexpectedly, he overestimated these peripheral meridians.

When he was divided into a hundred channels, his breath, which was obviously weak and almost unreasonably weak, poured into these peripheral meridians. In an instant, it nearly completely burst these peripheral meridians, so that he bled all over his body and turned into a blood man in a twinkling of an eye.

Fortunately, the influence of peripheral meridians on the body is too weak. In addition, for the sake of insurance, he chose to distribute the peripheral meridians in different positions of the whole body, which will not have a chain effect. On the contrary, it doesn't matter except that the whole body feels pain like acupuncture.

Chu Nan also didn't care to clean up the blood on his body. He concentrated and thought about it. There was an unusually weak breath everywhere in the elixir field, and then carefully explored in front of a terminal meridian connected with the secondary meridian.

This time, he first controlled the faint breath and tried at the entrance of the terminal meridians.

A trace of pricking pain rose again, making Chu Nan determine that this internal breath is still too strong for this peripheral meridian.

Then he called out a much weaker breath from the Dantian.

After repeated experiments for more than ten times, Chu Nan adjusted the internal breathing to at least ten times weaker than at the beginning, and finally successfully rushed into the peripheral meridian without causing any abnormality. He only felt a faint swelling feeling brought by the meridian.

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

Carefully controlling this faint breath, Chu Nan breathed a sigh of relief after crossing the terminal meridians.

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

Next, Chu Nan tested several peripheral meridians elsewhere, and successfully tested that the difference between peripheral meridians is also quite large. The internal breathing intensity suitable for opening them is the largest, and even the difference can be nearly dozens of times.

This discovery made Chu Nan feel a little tricky.

There are millions of terminal meridians in the body. If such tests continue, it will be impossible to complete them all until he dies of old age.

"So in the final analysis, we still can't use the normal method."

Chu Nan sighed, then calmed down and concentrated all his energy. A wisp of internal breathing was pulled out from the Dantian and instantly divided into 200 extremely weak internal breathing channels, which flowed into 200 different peripheral meridians.

Due to the previous test experience, only 13 peripheral meridians can not bear this time. All the rest allow the internal breathing to pass smoothly. Even some peripheral meridians are relatively strong, and there is no reaction after the internal breathing flows through.

Chu Nan was absorbed again, and a wisp of internal breathing was pulled out from the Dantian, which was instantly divided into 400 more exaggerated internal breathing.

Among them, 200 internal breathing channels flow into the 200 peripheral meridians tested before, and 13 internal breathing channels are adjusted to high-frequency vibration state to repair the damaged peripheral meridians. In addition, each channel of 187 internal breathing channels has different intensity, and they enter the corresponding 187 peripheral meridians respectively, which just makes the 187 peripheral meridians slightly damaged but not too much.

The data collected before can be used to determine the exact data of the internal intensity needed to get through the meridians, and then adjust the just perfect base note to strike the meridians. This is the standard practice for South Chu to open up meridians.

As for the other 200 internal breathing channels, they rush into the other 200 peripheral meridians, and repeat the process just now in these 200 peripheral meridians.

So while testing the data, he repaired and dredged the peripheral meridians, but he kept refining the peripheral meridians before. In the back, Chu Nan separated and maintained a full 1000 internal breathing channels in the body at the same time, and opened and destroyed and repaired a thousand peripheral meridians at the same time.

So many internal breathing channels with different intensities and even different vibration frequencies flow in the meridians at the same time. It is impossible for any martial artist to control them, but Chu Nan can accurately control them and play a corresponding role in thousands of peripheral meridians with the same accuracy.

This is the same as the bug general ability brought by the data ability of optical brain to Chu Nan. (to be continued)
