The whole Nebula college is shrouded in thick night. Even the street lights beside the road have turned on the late night mode, and the light becomes hazy.

The woods next to the boys' dormitory building of wuzhe branch are dark, but there is also a small group of hazy light in depth.

The soft light from the virtual screen of personal terminal reflects the highly concentrated face of Chu Nan.

The information on the virtual screen flashes quickly, and Chu Nan's eyes rotate at high speed with the information. These complex information is quickly incorporated into his mind, and then he uses the powerful data ability like an optical brain for high-speed calculation and analysis.

A moment later, the information scrolling on the virtual screen stopped, his eyes stopped, and then fell into thinking.

After meditating for a while, Chu Nan put his hands on the virtual screen, his fingers jumped, and a long channeling information flowed out on the virtual screen.

After leaving with Angie Belle and returning to his dormitory, Chu Nan has been thinking about how to help doraman solve his internal breathing skill problem.

This is not a whim, nor is it simply to help doraman.

In fact, in order to perfectly break through the pass of the universe and heaven as the venerable auveli said, he must create an internal breathing skill according to his own situation and make full use of his perfect physical conditions. Therefore, he has been studying the internal breathing skill for a long time.

Helping doraman solve his internal breathing skill problem is also helpful to his research.

In fact, doraman's problem is not just that his Saxon mind method is only an f-level internal breathing skill, which is not powerful enough. The biggest problem is that his martial arts skills don't match each other at all.

First of all, there is not enough match between the two external skills.

Zhenshan palm belongs to the kind of vigorous palm. It pursues open and close, with great momentum.

The lightning footwork is characterized by lightness and flexibility. If it is matched with it, it's best to be a flexible palm technique.

If you use Zhenshan palm technique with lightning footwork, it will appear a little nondescript and even conflict in some places. No wonder doraman was difficult to practice well in the past.

However, this is the problem of external skills after all, and Zhenshan palm technique and lightning footwork are all f-level skills. With strong data ability, Chu Nan can easily improve these two skills, combine them, and make doraman easily understand palm grip.

But the problem of internal breathing skill is not so easy.

The internal breathing skill of doraman cultivation is Saxon mental skill. The internal breathing characteristics of this mental skill are soft and tenacious. It is a good internal breathing skill in level F martial arts.

However, the characteristics of this skill are not matched in Zhenshan palm and lightning footwork. The internal breathing characteristics of these two external skills are strong and explosive, which is not possessed by Saxon mind method. Therefore, doraman is difficult to combine internal breathing with his most skilled external skills, and his natural strength is very weak.

Of course, his internal breathing intensity is not high now, so this effect is not obvious.

However, if he wants to pursue higher strength, he must make a choice between external martial arts and internal breathing skills.

Either re cultivate other external skills with Saxon mind method, or directly change to a vigorous and explosive internal breathing method to re cultivate internal breathing.

For doraman, these two choices are impossible, because he was originally the kind of person who was difficult to get in touch with a variety of martial arts. Any martial arts he mastered now are very valuable and he can't give up easily.

But for Chu Nan, this choice is very simple.

Doraman's internal breathing is so weak now. It's better to waste and practice again.

Besides, Chu Nan is not interested in studying the low-level martial arts combined with Saxon's mind method. The most important thing is to study the internal breathing skill.

In fact, Chu Nan now has much more low-level skills than ordinary martial artists.

In addition to exchanging nearly 200 f-level and d-level martial arts in the martial arts database of wuzhe branch, he also came into contact with a large number of low-level martial arts when cooperating with nuoyantum chamber of Commerce. If they add up, they are nearly 300.

Among these, there are more than 50 internal breathing exercises, although they occupy an absolute minority.

Chu Nan originally intended to throw one suitable for doraman to him from these low-level internal breathing skills he mastered, but later he thought of a problem.

Among the martial arts he mastered, the martial arts from the martial arts database cannot be easily taught to others because of the college regulations.

The agreements between Yan Nuo and Wu Nuo can't be easily signed because they come from Yan Nuo's chamber of Commerce.

Therefore, although he has mastered nearly 300 martial arts and more than 50 internal breathing skills, he can't take them out to doraman.

In desperation, Chu Nan can only find another channel to find the appropriate internal breathing method.

After all, he is not a warrior with a strong background, so the only way to solve this problem is to ask for help online.

Due to the prosperity of martial arts on the rotating arm of Orion, there are many discussion forums on martial arts on the pan Galaxy network. Chu Nan directly entered the Earth Federation Martial Arts Alliance, which he used to visit before, and found the version of martial arts mutual assistance and exchange. It's easy to see a pile of posts that publicly sell martial arts skills.

This place is a bit similar to the martial arts exchange meeting that Chu Nan attended in xiyunxing. All kinds of martial arts will be directly brought out for sale at a clearly marked price.

Because this is a pan Galaxy network, the scale is actually dozens of times stronger than the small warrior communication on Xiyun star.

Chu Nan searched according to the conditions related to the internal breathing skill, and more than 100000 pieces of relevant information jumped out at once.

Even if the search scope is limited to f-level martial arts, there are more than 80000 relevant information.

This is not surprising, because the more high-end martial arts, the less people will master them, and only low-level martial arts will be put on public sale.

As the lowest level of martial arts, level F martial arts has the most martial arts masters and the most naturally related martial arts.

Chu Nan then limited the search scope to the internal breathing skill, which is characterized by being strong and explosive, and the relevant information was filtered to only more than 10000.

However, there are still too many of them. Chu Nan took a look at several skills with the highest comments and the highest praise rate, but found that the price of these skills is too high. The one with the highest praise rate even costs up to 150000 federal dollars!

Chu Nan couldn't afford the price himself, so it was more impossible for him to spend so much money to buy it for doraman.

After thinking for a while, Chu Nan decided to focus on those martial arts that cost less.

Although these martial arts must have some defects, Chu Nan believes that with his strong analysis ability of martial arts, he can improve any martial arts well enough.

Soon, he locked in a level f internal breathing skill called "Zhenshan divine skill".

The reason for choosing it is not only that the price marked on it is only one thousand federal dollars, but also because its name is very close to doraman's Zhenshan palm, which will look full of collocation together.

After determining that the characteristics of this skill should be very suitable, Chu Nan pressed the purchase button.

Seeing the payment window that immediately jumped out, Chu Nan was stunned. (to be continued)
