"Bang-"

A dull explosion of air spread through a remote grove at Xiyun Academy.

Chu Nan withdrew his fist and nodded in satisfaction.

The experience gained during the day's battle with Asaru was useful.

After returning to the academy, according to his experience during the day, he used the Nine Turns Mind Method to mobilize the internal breath while practicing boxing on his own, and he was able to smoothly integrate the internal breath into the fist, thus greatly increasing the strength of the fist.

In fact, he deliberately did not take a very perfect posture for this punch just now, and exerted the strongest physical strength that this style of horse punch can exert, but after cooperating with internal breath, the force attached to this punch is still as high as 623.371892 kilograms.

You must know that even if he is in the most perfect state when he usually practices boxing, the maximum force attached to a punch using a horse punch is only 473.739238 kilograms.

Chu Nan did not continue to practice, but closed his eyes and felt the subtle conditions of his body when he punched just now.

After a while, his body sank slightly, and he punched out the same style of sitting on the horse.

As soon as half of the punch was struck, Chu Nan's face suddenly flushed, his mouth opened, and a mouthful of blood spurted out, his arm instantly became sore and weak, and his fist hung down.

He took a deep breath, quickly calming his breathing, which had suddenly become chaotic and rapid.

In this punch, although he also used the Nine Turns of the Heart Method to mobilize the internal breath, he did not deliberately cooperate with this punch, and as a result, when he punched, the flow of the internal breath in the meridians in the body just clashed with the muscles mobilized by the punch, which immediately made him feel the blood and qi in his body surging, and almost became the legendary madness.

It took Chu Nan a while to completely calm down his internal rest, reached out to wipe the blood from the corner of his mouth, and smiled self-deprecatingly.

It's really like I want to run before I even learn to walk.

Now he has just figured out a trace of the law for the random mobilization of internal breath in battle, and he is trying to mess around, which is simply looking for death.

However, this is also because of the help of strong data ability, which allows him to perceive every data in his body with great surprise, and can adjust it back in time before an accident occurs.

What's more, through this experiment, he once again confirmed the speculation in his heart.

The mobilization of internal breath can only be perfectly exerted when it is coordinated with body movements, otherwise, it is self-inflicted.

After confirming this, Chu Nan simply sat down and started the Nine Turns of the Heart Method, while using the internal breath according to the usual cultivation method, while carefully perceiving the trajectory of the internal breath flowing in the various meridians in the body.

In fact, these tasks had already been completed very well when he broke through the third level of the Nine Turns Mind Method before, and now he was just using the internal breath with the three moves and twelve styles of Hong's Long Fist simulated in his mind.

After repeated nine turns like this, while Chu Nan had recovered from a trace of meridian contusion that he had just suffered due to his rash experiment, he had also further confirmed the details of the coordination between the boxing technique and the internal breath.

Chu Nan used his legs hard, jumped up from the ground, and punched out without hesitation.

"Bang-"

The force of the fist with internal breath was as high as 693.739231 kilograms, and a single punch easily made a dull air explosion sound.

"Bang-"

Another punch, the force has already exceeded 700 kilograms.

"Bang-"

One more punch......

……

Soon, Chu Nan had already practiced the three moves and twelve styles of Hong's long fist, except for one type of horse hook and one type of horse shooting fist, the other ten punches all successfully mobilized their internal breath, causing a series of angry sounds in the grove.

Chu Nan paused for a moment, and in his mind, he connected the two movements of retreating horse hook and shooting horse holding fist with the meridian operation of the Nine Turns Heart Method to mobilize internal breath, thought carefully for a while, and punched out.

With his incomparably strong data ability, he only experimented less than ten times, and then successfully found the trajectory of the internal breath flow meridian and the two types of punches, and mobilized the internal breath in these two styles.

"Good."

Chu Nan nodded, and punched out again with a horse rush.

It didn't take long for him to fully practice Hong's long fist again.

This time, in a total of three moves and twelve styles, each punch and each style successfully mobilized the internal breath.

However, unlike the previous time when he successfully mobilized his internal breath during his boxing practice, this time Chu Nan did not have any mysterious and indescribable feeling, but clearly knew how his internal breath was successfully mobilized and how it was integrated into his boxing moves.

He didn't like the so-called mystical state of being inexplicable, because it meant that he didn't really understand it at all.

After thinking about it for a while, he punched out at random, but he failed to mobilize the internal breath cooperation.

"Sure enough."

Chu Nan nodded, knowing that Hong's long fist was indeed an extremely special fist technique, which allowed him to easily use the Nine Turns Mind Method to mobilize the internal breath and integrate into it, and if he just punched out at will, it would be difficult for the physical body to integrate the internal breath into it, and naturally he could not mobilize the internal breath assistance.

If you want to be able to transfer the internal breath at will between gestures, only if the internal breath is deep enough, it is possible to at least reach the standard of the internal breath-level martial artist.

And even if it is an internal breath level martial artist, he also needs a strong martial art to maximize his internal breath, and it is not possible to meet the requirements with a random punch.

Thinking of this, Chu Nan couldn't help but laugh.

The 5,000 Federation Coins spent at the Warrior Exchange Meeting before were really worth it!

After recalling the process of practicing boxing just now a few times in his mind, Chu Nan took a pose again and punched out.

Successfully mobilizing the internal breath was only the first step, and the next work he needed to complete, as he had done when he had broken through the third level of the Nine Turns of the Heart Method, was to make more refined and precise changes to make the internal breath that could be integrated into the fist more quickly and powerfully.

The punch was punched out by a horse, but the force was about two kilograms less than the punch in the previous drill.

Chu Nan shook his head, knowing that this experiment of altering a meridian of internal breath flow when mobilizing internal breath was a failure.

He thought about it for a moment, and punched out again with a horse rush.

The strength of this punch is 3.739619 kg more than the punch in the previous drill!

Chu Nan was overjoyed in his heart, and made changes according to this basis again, but he didn't expect that his strength would be reduced by about 7 kilograms all of a sudden.

He was not discouraged, and punched out again with a horse rush.

The previous time I changed the cultivation method of the Nine Turns of the Heart Method, I had already accumulated enough experience.

If you want to change your martial arts and turn them into the most suitable martial arts for you, it requires a lot of training and experimentation over a long period of time, and it is by no means something that can be completed overnight.

He didn't even have this opportunity before, but now he finally got this opportunity with his strong data ability and his own understanding, as well as a little luck, so he naturally had to take advantage of it.

"Bang-"

Another punch was struck.

The force on this punch is as high as 712.739691 kg! That's an increase of more than 3%!

Chu Nan felt a burst of joy in his heart, and was about to strike another punch, when he suddenly heard a shout from behind.

"Good punches! Chu Nan, look at the palm! ”

As soon as the call fell, a special palm wind struck from behind.
