Late at night.

Only the sounds of small animals could be heard on the farm, causing the surroundings to be extremely silent.

Like every night for more than a month, Chu Nan did not sleep immediately. Instead, he sat on the bed and calmly cultivated the Nine Revolutions Technique.

After breaking through the fifth level and completing the basic meridians, the feeling when he cultivated the Nine Revolutions Technique was completely different from before.

Before this, when Chu Nan was cultivating the Nine Revolutions Technique to increase his Internal Breath, he could only feel his Internal Breath circulating in a small portion of his meridians. Then, his body, which was affected by this small portion, became extremely weak.

However, now, after circulating his Internal Breath in the meridians that were opened according to the fifth level of the Nine Revolutions Technique, he would feel every part of his body being affected by his Internal Breath, and his entire body would be strengthened.

This change was not obvious in the nearly perfect body part that he had tempered previously, but it was very obvious in the body parts that had not been tempered enough previously.

After his Internal Breath flowed, Chu Nan could even sense a strange feeling of soreness and swelling in many parts of his body.

This feeling was familiar but also unfamiliar.

What was familiar was that when he first came into contact with the Nine Revolutions Technique to cultivate, when he successfully completed the circulation of one cycle of Internal Breath for the first time, he had this strange feeling.

What was strange was that this feeling had been happening for 13 years.

Chu Nan knew very well that the reason why he felt this again was because his body had been tempered very badly before this. There were many places where even his muscles had not been completely tempered.

The reason why this situation occurred was precisely because he had not been able to break through to the fifth level of the Nine Revolutions Technique previously, causing his Internal Breath to be unable to truly circulate throughout his body.

Now that he was cultivating the fifth level of the Nine Revolutions Technique, his Internal Breath could affect his entire body. Those places that had not been tempered before could be further tempered, and they would gradually be consistent with the other parts that had been tempered before.

Strictly speaking, although Chu Nan could already circulate his Internal Breath throughout his entire body and casually use it, and even unleash his Internal Breath, he could be considered a qualified Internal Breath Martial Artist. However, only after his body was tempered and perfected could he truly complete the transformation from an Overlord Body Realm Martial Artist to an Internal Breath Realm Martial Artist.

Feeling the soreness and swelling in his body, Chu Nan continued to maintain the smooth circulation of his Internal Breath as a question arose in his mind.

Be it the two Star-Grade Martial Artists or Rengal, they both felt that it was very difficult for them to break through the Cosmic Heaven’s Gate. The reason was that he was already an adult and his body was basically fixed. There were some places that he had not been able to refine and perfect before that could not be truly tempered. Therefore, when he broke through the Cosmic Heaven’s Gate, he would encounter an insurmountable obstacle that he could not break through.

However, where were these places that could not be tempered and perfect?

After circulating his Internal Breath for another cycle, Chu Nan stopped cultivating. He thought for a moment and shook his head, knowing that no one was waiting to give him an answer.

The physical condition of every martial artist was different, and the Internal Breath cultivation method they cultivated was also different. Even if they cultivated the same Internal Breath cultivation method, the exact situation when they cultivated was still different. Then, the exact situation of the body refinement of every martial artist was naturally worlds apart.

Rengal could only tell Chu Nan that his body might be defective, but he could not tell him what the flaw was.

After all, this was Chu Nan’s body and no one could understand it so clearly.

When he thought of this, Chu Nan stopped his cultivation and opened his personal terminal to pull out a large pile of human data analysis reports.

Not only was Chu Nan involved in these reports, but there were also many other martial artists at the initial-stage Internal Breath Realm. All of them were the data that Yu Tingfeng and Dong Fang had gathered for him.

After Chu Nan obtained these data, he used them to compare in detail.

He originally hoped that these detailed data comparisons would find out where his physical flaws were, but after using his powerful data ability to carefully compare all the data analysis reports, he discovered that he was doing nothing.

The number analysis report of every initial-stage Internal Breath Realm Martial Artist was different. The only pattern he could find was probably equilibrium.

The so-called equilibrium referred to the fact that every aspect of the body’s data was in a fixed range without any obvious deviations.

Although some initial-stage Internal Breath Martial Artists clearly had stronger muscles and some bloodlines were tougher, they did not show it too exaggeratedly, and no initial-stage Internal Breath Martial Artist was especially disadvantaged in a certain aspect.

Compared to them, Chu Nan’s human data analysis report was clearly much worse.

Chu Nan still could not understand the reason for the problem… There were actually too many problems.

From his own human data analysis report, be it muscles, blood vessels, or the most important bones in his body, there were several or even dozens of places that were clearly different from the value of his entire body.

This meant that if Chu Nan wanted to reach the equilibrium standard of those initial-stage Internal Breath Realm Martial Artists, he had to make up for all these flaws.

This was clearly because Chu Nan’s previous cultivation was not strong enough and he was unable to break through to the Internal Breath Realm before his adult body completely took shape, causing his body tempering to be incomplete.

If he wanted to make up for these flaws, it was clearly impossible to cultivate normally according to the normal method.

Chu Nan did not know how to start previously, but after breaking through the fifth level of the Nine Revolutions Technique today and sensing the change that cultivating the fifth level brought to his body, an idea arose.

The flaw in his body was because he had not been able to break through to the Internal Breath Realm previously and was unable to successfully circulate his Internal Breath throughout his entire body to temper his entire body.

Now that he had broken through to the Internal Breath Realm, his Internal Breath could still produce a certain tempering effect on his body, proving that it was still effective until now.

In that case, as long as he strengthened this effect, would there be hope of completing the refinement before his body was truly fixed and there was no possibility of tempering it anymore?

As for how to do this… Chu Nan placed his gaze on the remaining meridians in his body that had yet to be opened.

The fifth level of the Nine Revolutions Technique had only opened 68.3% of the main meridians and secondary meridians, but it could already let Internal Breath affect every part of the body. Then, if he opened the other meridians, wouldn’t there be a hope of better letting Internal Breath affect the entire body and refine any part?

When he participated in the experiment at the Noctem Chamber of Commerce this afternoon, he cultivated many other Internal Breath cultivation methods according to the requirements of the Noctem Chamber of Commerce. Among them, there was a cultivation method that forced him to open a major meridian that he had never opened before.

The internal cultivation method was a low-level and simple cultivation method, so the effect was naturally inferior to the Nine Revolutions Technique. However, when Chu Nan cultivated it, he clearly felt that the effect on his body was slightly different from cultivating the Nine Revolutions Technique.

Just opening one more main meridian could produce this effect. If he opened all of them, could he find more effects?

With these two thoughts combined, Chu Nan composed himself.

He did as he thought!

With sufficient experience of ‘rough’ opening his meridians many times, Chu Nan did not have any psychological barriers when it came to opening his meridians. With a thought, an Internal Breath surged out from his dantian and divided into 21 weaker Internal Breaths that surged into the 21 main meridians that had yet to be completely opened.

An hour later, these 21 main meridians were completely opened. Moreover, in the special refinement method that belonged to Chu Nan, they had a toughness that was enough to endure the circulation of his Second Revolution Internal Breath.

Chu Nan did not stop and focused his gaze on the remaining 93 meridians that had not been completely opened.

He also noticed those at the end of the fine meridians that were much smaller and more fragile than the main and secondary meridians…
