The greatest difference between an Overlord Body Realm Martial Artist and an Internal Breath Realm Martial Artist was that an Internal Breath Realm Martial Artist could mobilize his Internal Breath to his entire body at will and easily unleash a huge power with his external cultivation moves. Under normal circumstances, his strength would naturally far surpass an Overlord Body Realm Martial Artist.

Although Overlord Body Martial Artists could also mobilize their Internal Breath, they either cultivated a special Internal Breath cultivation method and could casually mobilize their Internal Breath at the Overlord Body Realm or relied on the special external martial technique, the Hong Clan’s Long Fist, like Chu Nan, to complement their powerful data ability and perfectly fuse the trajectory of their Internal Breath and fist technique to achieve the effect of fusing their Internal Breath into their moves.

However, no matter what, it was impossible for Overlord Body Martial Artists to mobilize their Internal Breath as they pleased like Internal Breath Martial Artists, allowing every move and move to complement their Internal Breath.

Not even Chu Nan could do it.

The reason was very simple. Because the meridians of an Internal Breath Realm Martial Artist were all opened, they could naturally mobilize their Internal Breath to any part of their body, allowing every move and style to be fused into their Internal Breath.

On the other hand, the cultivation methods of Overlord Body Realm Martial Artists were different. The levels tempered by the body were different, and the meridians opened were also different.

However, even a fifth-stage Overlord Body Martial Artist could not open all the meridians in his body.

This was because being able to do this meant that he had already become an Internal Breath Realm Martial Artist.

What Chu Nan needed to do now was to completely open up all the meridians in his body and raise himself to the level of an Internal Breath Martial Artist.

After breaking through to the fourth level of the Nine Revolutions Technique, Chu Nan had opened up seven more main meridians and 26 secondary meridians than when he was cultivating the third level.

According to the Nine Revolutions Technique left behind by Su Xuansheng back then, when Chu Nan tempered the newly opened seven main meridians and 26 secondary meridians to the extent that his Internal Breath could circulate freely, he could open more meridians and attempt to break through to the fifth level of the Nine Revolutions Technique.

If it was in the past, Chu Nan would have followed the instructions of the cultivation method indicated by the fifth level of the Nine Revolutions Technique. He would then open up the 11 primary meridians and 39 secondary meridians marked by the fifth level of the Nine Revolutions Technique. Then, he would slowly refine them and reach the realm of the fifth level of the Nine Revolutions Technique, shown by “Internal Breath circulating throughout the body as he pleased”. He would become an Internal Breath Martial Artist like everyone else.

However, Chu Nan had other thoughts now.

According to the cultivation method indicated on the fifth level of the Nine Revolutions Technique, if Chu Nan opened eleven main meridians and 39 secondary meridians, coupled with the meridians that he had already opened, it was enough to let these meridians affect nearly every part of his body and allow his Internal Breath to circulate normally and affect every inch of his muscles.

However, after an accurate comparison, Chu Nan discovered that even if he completely opened these 11 primary meridians and 39 secondary meridians, the meridians opened in his body only accounted for 68.3% of the meridians in his entire body.

Just the main meridians alone had a total of six that had not been opened. There were as many as 32 secondary meridians that had not been opened. It could not be said to have truly opened all the meridians in the entire body.

In fact, Chu Nan knew very well that this was normal.

The meridians in the human body were extremely complicated. If one wanted to really open every meridian, there was actually not much meaning.

This was because even if many meridians were opened, the effect was usually similar to the meridians beside them. It could not increase or help much at all. Instead, it might cause a problem for a martial artist when circulating their Internal Breath.

Therefore, the Internal Breath cultivation methods that were passed down now would actually only choose to open a portion of the meridians and let the Internal Breath circulate through these meridians through a certain method, obtaining varying degrees of improvement.

As long as he could mobilize his Internal Breath to every part of his body, it could be said that his meridians had been opened.

Different cultivation methods had different effects.

This was the true difference between different Internal Breath cultivation methods.

Of course, the higher the cultivation method, the deeper the research on the meridians. The more meridians needed to be opened.

When one cultivated the Nine Revolutions Technique to the fifth level, they had to open up 68.3% of their meridians. In Chu Nan’s opinion, this was already very outstanding.

Although he had not grasped more Internal Breath cultivation methods and could not compare, the results of his data collection and analysis showed that if his Internal Breath circulated in these meridians marked by the fifth level of the Nine Revolutions Technique, it could indeed obtain a nearly perfect increase.

Just this point alone proved that the Nine Revolutions Technique was indeed worthy of being the powerful Internal Breath cultivation method that allowed Senior Su Xuansheng to dominate the Milky Way back then. It was far from the trash cultivation method that many martial artists thought of later on.

The reason why it could not become popular on a large scale was completely because when Senior Su Xuansheng left this cultivation method on the Milky Way Network back then, he had only left behind a cultivation method according to his own situation. However, he had not modified it from the perspective of the public—or rather, reduced the difficulty of cultivation.

In short, he did not have any experience teaching disciples.

This made the introduction of the Nine Revolutions Technique extremely difficult. Chu Nan had cultivated for 13 years but had only reached the second level. It was extremely difficult to take another step.

If not for the fact that Chu Nan had later obtained a powerful data ability that allowed him to clearly know the increase in the circulation of his Internal Breath in his meridians and make the corresponding modifications, he might not have been able to break through to the third level even if he cultivated for another 13 years.

However, now, through the continuous destruction of his meridians and repairing such a cruel and inhumane method, Chu Nan had already tempered the seven major meridians and 26 secondary meridians that had been opened after breaking through the fourth level to a certain extent. Therefore, breaking through to the fifth level was already very easy for him.

The difficult thing was how to truly open up all the meridians in his body and modify a cultivation method that was more suitable for him on the foundation of the Nine Revolutions Technique.

Chu Nan did not consider how to cultivate his Internal Breath in the future. The first problem he needed to resolve was how to open the remaining meridians.

After a moment of thought, he decided to first open the eleven major meridians and 39 secondary meridians that needed to be opened by the fifth level of the Nine Revolutions Technique.

With the experience of breaking through the fourth level and opening his meridians, this job was not difficult for Chu Nan.

The last time he broke through to the fourth level, for safety’s sake, he only used his Internal Breath to slowly test his meridians.

With his previous experience, Chu Nan simply mobilized a wave of Internal Breath from his dantian and instantly divided it into 11 more thin and weak Internal Breaths. They flowed through the different meridians in his body and flowed to the main meridians that needed to be opened.

To ordinary martial artists, it might be possible to mobilize two or three different Internal Breaths and circulate them in their bodies at the same time, but it was impossible to mobilize eleven Internal Breaths at the same time.

This was because even if a normal human could multitask, it was impossible for them to deal with 11 different actions at the same time. Naturally, it was impossible for them to perfectly control the 11 strands of Internal Breath.

If he was not careful, he would lose control of his Internal Breath and suffer a cultivation deviation.

However, because Chu Nan had the support of an extremely powerful data ability that was equivalent to an A.I., it was simple for him to deal with 11 strands at the same time.

Eleven strands of Internal Breath rushed into the eleven main meridians that needed to be opened at the same time. Chu Nan quickly obtained extremely detailed and precise data from the reaction of these meridians.

Then, he retracted these 11 Internal Breaths and pulled out an Internal Breath from his dantian, splitting it into 11 Internal Breaths of varying strength.

According to the feedback data Chu Nan had gathered, he controlled the 11 Internal Breaths to enter the eleven corresponding main meridians again.

Hiss!

As soon as the 11 Internal Breaths entered the eleven main meridians, Chu Nan immediately could not help but gasp. He was almost jolted away by the strange feeling of soreness, numbness, and itchiness that appeared at the same time in his entire body as if there were needles continuously stabbing his body.

Although he had experience, he had only slowly opened up one meridian after another previously. Now, 11 main meridians were “working” at the same time. Chu Nan completely underestimated the terrifying feeling brought about by such an accumulation.

Fortunately, his mind had long been tempered to be extremely tough under the damage of the previous few meridians. Even if it was extremely uncomfortable, he still gritted his teeth and persisted. It was even to the extent that he was still able to extremely accurately control the 11 Internal Breaths and complete the initial opening of the 11 major meridians.

It felt like a few months had passed, but in fact, in just a few seconds, the eleven Internal Breaths had already completely cleared these 11 major meridians.

According to the description in the cultivation method manual, the 11 main meridians that needed to be opened up to the fifth level of the Nine Revolutions Technique would normally require at least three months to begin the initial circulation.

However, Chu Nan only used less than ten seconds!
