After Li Mu took the Dayan Dan, the Ren and Du meridians were connected. Naturally, he chose the way of "Sunflower Book" and started from the acupuncture points in the Ren and Du meridians, connected into a line, and finally gathered in the dantian.

The "Acupuncture and Moxibustion Jia Yi Classic" records that the Ren meridian runs in the midline of the ventral face. Its meridian meets the three Yin and Yin Wei meridians of the hands and feet many times, and can sum up the Yin meridians of the body, so it is called "the sea of ​​Yin meridians".

The Du meridian runs in the middle of the back. Its meridian meets the three Yang meridians of the hands and feet and the Yangwei meridians many times, and can govern the Yang meridians of the whole body, so it is called the "Sea of ​​Yang meridians".

Seeing these two explanations, two names suddenly appeared in Li Mu's mind.

"Nine Yin Scriptures", "Nine Yang Scriptures".

Could it be that these two martial arts are the unique skills of the "Ren Mai" and the "Du Mai"?

This possibility cannot be ruled out.

If you greedy for too much, you won’t be able to make a big deal. If you choose between yin and yang, Li Mu will naturally choose the ‘yang meridian’. Otherwise, you will start with the ‘yin meridian’. If you become Yue Buqun, you will have nowhere to buy medicine if you regret it.

It's settled, Du meridian!

So where to start?

Li Mu found another "reference book", "Huangdi Neijing".

In "Huangdi Neijing: Su Wen Gu Kong Kong Yin Chapter 60", it is recorded that the Du meridian originates from the center of the bone below the lower abdomen... (too long, omitted).

Simply put, the Du meridian starts at Changqiang point and ends at the Gingjiao point. There are 29 single acupoints, namely Changqiang, Yaoshu, Yaoyangguan, Mingmen, Xuanshu, the spine, the center, the tendons shrink, Zhiyang, Lingtai, Shendao, Body pillar, Taodao, Dazhui, Yamen, Fengfu, Naohu, Qiangjian, Back-top, Baihui, Anterior-top, Foshanhui, Shangxing, Shenting, Sulu, Shuigou, Duidun, Gingjiao, Yintang.

What Li Mu has to do now is to find a running order that can make the "qi" run smoother. This involves a "simple" mathematical problem, namely: set each acupoint as a letter. How many possibilities are there for the twenty-nine letter arrangement and combination, which is equivalent to cracking a twenty-nine-digit password.

If the password is composed of twenty-nine digits, each position may be any number among the twenty-nine letters, so there are twenty-nine possibilities for each position, and the probability formula is 29X29X29..., twenty-nine multiply twenty-nine times, twenty-nine to the twenty-ninth power of twenty-ninth, 2.5676861531612e42 times.

It seems like a very huge number, but there is no way to calculate it at all. But there is no need to worry. Humans have about tens of billions of brain cells, each brain cell has about hundreds of brain nerves, and each nerve has about hundreds of synapses, and each synapse has hundreds to thousands of proteins. The role of a brain cell is about equivalent to a large computer, and the role of a synapse is about equivalent to a chip of a computer. It can be simply calculated that the human brain is equivalent to hundreds of billions or trillions of chips.

As a senior data balance designer, how could Li Mu have never thought of trying to use his brain to calculate through the system? This is a fantasy idea, but don’t forget that time travel has happened and the system has brought it over, so what else can’t happen?

After several attempts, Li Mu finally found a way to use the "brain" calculation through the system. In other words, he entered the recovery mode of the system, which is not uncommon, because he was originally the developer of this system. And as a data balance designer, he has the underlying permissions of this system.

However, after traveling through the Tang Dynasty, the system also changed a lot. His developer permissions were curbed. Now the permissions he has can basically "run data", from "read-write" to "read-only", and nothing can be changed. But it doesn't matter, what he needs now is just "run data".

The level of brain development for everyone is limited, and it is impossible to reach 100%. The average person's brain development level is about 100%, and it only takes 150% or even 20 in a few days. That is already the light of human beings. Li Mu is not sure how much his brain has developed, so he only uses "one percent" of brain cells to "run data". To describe it as a computer term, his CPU utilization rate is only one percent.

This is a little bit stuttering, so when he is "running data", he is in a daze and has a very slow reaction to the outside world. In this way, he will naturally not be able to recruit the best running route in a short period of time, but it doesn't matter. The accumulation of internal forces can be accumulated, whether it is fast or slow accumulation. The method Li Mu currently uses is to "run the data for a while", and then find the existing best route among the data that is running out to start luck. Then, the next time he is "running data", if he finds a faster route, it will be changed to a better route. If he does not find a better route, he will still use the original route.

In this way, he uses the best route every time he uses the existing one, and the data is limited, so he can finish it sooner or later. Even if he can’t finish it, Li Mu doesn’t believe he is so unlucky. After running for ten or eight years, he still can’t find a ‘relatively excellent’ route.

Dugu Jiu lifted the curtain and looked at Li Mu lying on the bed. He was puzzled. He had just asked Li Mu what he was doing. Li Mu said he was practicing internal skills, but Dugu Jiu saw others practicing internal skills, sitting cross-legged, pinching his hands, or facing the sky, so-called three flowers gathered to the top, and five energy faced the Yuan Dynasty. None of them was lying on the verge of Li Mu. He looked like he was sleeping. But he was open again, his eyes were dull...

"Is it a brain disease?"

Dugu Jiu murmured in his heart, planning to return home and tell Bai Qiaoqiao about Li Mu's situation. Although Li Mu usually smiles and doesn't have any airs to treat people around him, he basically won't listen to what anyone says. The only thing that the whole family can control him is Bai Qiaoqiao.

One hour later, the carriage arrived at Xiaoyao Valley.

Li Mu got off the carriage and took a breath of fresh air in the mountains and forests, and felt refreshed. After an hour of practice, Li Mu deeply felt that his dantian Qihai had expanded a little more.

Regarding the thing "qi", Li Mu has a very different understanding of "experts" like Sun Simiao and Eunuch Gao. He did not think of the thing "qi" so mysteriously, and understood it from the perspective of a game designer. What is Qi?

Qi is blue, blue bar! What is Dantian Qihai? Dantian Qihai is the maximum value of the blue bar, that is, the MAX. The higher the level, the higher the maximum value, the more skills you can use. Isn’t it very simple?

The same principle can also be put on people like Dugu Jiu and Li Chongyi who do not practice internal skills.

Li Chongyi is a violent battle. He does not have a "blue bar", but he has a "red bar". When he is angry, his eyes are red, which is obviously a manifestation of anger explosion. With the same blow, the damage of full anger is naturally higher than that of low anger damage.

Dugu Jiu is an assassin. He has no "blue strip" or "red strip", but he has "yellow strip" and energy strip! His martial arts are smart and light, and he specializes in picking flaws. Isn't this a "weak attack"? It's the same attack, stabbing on the butt and throat, and the effect is naturally different!

After understanding these principles, Li Mu suddenly felt that he was fully understood. This is how genius was. He had thoroughly understood things that mortals could not understand in their entire lives in just a few days!

"Life is so lonely as snow!"

Dugu Jiu had just tied the horse up and heard Li Mu's voice, saying, "Brother, what did you say?"

Li Mu turned around and said, "Brother, I have understood the essence of internal strength. It's not to be hidden. I will not be able to long before I will be a master of internal strength. Do you want to learn? Call me "Brother, will I teach you?"

Dugu Jiu looked at Li Mu worriedly, thinking that the elder brother might have really been sick and dared not provoke him, and said, "Didn't I always call you elder brother... But, brother. You should be more cautious when practicing qigong. The internal strength is not as good as external strength. If you are not good at practicing external strength, you will be injured at most. But if you are injured in practicing internal strength, the consequences will be serious."

"Serious?" Li Mu asked curiously: "How serious can it be?"

"I heard that some people are so crazy about practicing martial arts, they become fools. Some people have become traitors with their personality changes, and they are sarcastic, like eunuchs."

"Uh..." Li Mu's heart trembled for a moment, but then he felt relieved. His practice method was the "optimal solution" calculated by "running data", and it was impossible for him to have problems.

"I will be careful." Li Mu changed the topic and said, "Let's go and see how the barbecue is ready."

After saying that, he took Dugu Jiu to the west bank of the stream, near the hillside on the west side, and had already sorted out an open space, and the cut wood was placed next to it. Two tall Turkic people were playing barbecue racks. Seeing Li Mu coming, one of them hurried over and spoke with Li Mu in extremely stiff Chinese, mixed with Turkic dialect.

These two people are Ada A Er from the West City. They were left in Chang'an by Zhang Xun. As Li Yourong's contact person, they opened a barbecue shop in the West City. Li Mu often ate in the West City, and because he had received Anise from the two of them before, they suffered a prison disaster. He often visited their shops. The barbecue skills were really good. This time Li Mu invited him to Xiaoyao Valley, one to solve the problem of eating for the students, and the other to help them.

Li Mu gave them five stagnant money every day, which was almost double their daily income, and it was really not a slow deal.

Li Mu looked at the sun and according to his plan, about half an hour, the students with good physical strength should arrive. Li Mu told Ada and A Er to make a fire quickly. He promised that the students could drink and eat meat when they arrived, but they could not break their promise.

However, one person's speed was beyond his expectations.

The first person to arrive at Xiaoyao Valley was the "twenty-nine-year-old" young man Ma Zhou. It only took him a little more than an hour to change the time of Li Mu's previous life, about two hours and twenty minutes.

It is actually not fast to run twenty miles in two hours and twenty minutes. People who run marathons can run forty miles at this time. However, when Li Mu estimated that most of the people who signed up were "rich second-generation" who had a little money at home, they naturally had to go to a few levels of physical strength for these people.

Ma Zhou looked very weak, and it was already very good to be able to run so fast. Li Mu encouraged him a few words and asked him to sit next to him and wait. He felt a little disappointed with the physical strength of these students.

Ma Zhou is the oldest among these people. Li Mu set a requirement that he was under 30 years old. Ma Zhou is 29 years old this year, which is equivalent to registering for "crossing the line". But he ran first, which shows how poor other students' physical strength is.

Li Mu stood at the entrance of the valley with a cold face. As he went from one another, his face became increasingly ugly.

It was noon, and there were only more than 130 qualified people. When we set out, except for the eighteen latecomers, there were still 288 people left. In other words, half of them were eliminated at this level. After 20 miles, they were all eliminated in four hours!!

What made Li Mu most angry was that none of Tang Guan, Wang Pu and Changsun Chong had arrived yet. There was still a quarter of an hour before noon, and Li Mu no longer had hope.

"If they can't escape, they will never let them enter the Ministry of Internal Affairs. The rules are dead. If they fail, they will be eliminated!"

Li Mu silently murmured in his heart that no one can give him any face this time, and there is absolutely no back door.

Time passed by little by little, and suddenly a shadow appeared in front of him, which turned out to be Wang Pu! When he saw Li Mu, he raised his hand and waved it, but he obviously had no strength. He didn't even have the strength to shout, and moved step by step.

It was only today that Wang Pu realized that his physical strength was so bad. Although he was only thirty years old, his years of life in a playboy had emptied his body, but he just didn't know it.

Suddenly, another person appeared behind Wang Pu, which was Tang Guan. Tang Guan bit the ball tightly, ran hard for a while, successfully crossed Wang Pu, and ran to Li Mu first, and slapped on the ground, as if he was dead, without any sound.

After all, Tang Guan was young and lacked endurance, but he recovered quickly. The strategy he adopted was completely different from Wang Pu. Wang Pu gritted his teeth and ran hard, and walked away if he couldn't run. Tang Guan ran for a while and rested for a while. But he was not much better. As an editor of the "Da Tang Daily" who kept in his room all day long, he walked only a few hundred steps every day, and he didn't exercise at all.

Finally, Wang Pu moved to the place, looked at Li Mu with resentment, and sat on the ground.

Seeing that time passed, Li Mu gave up the last possibility. It seemed that Changsun Chong still couldn't hold on until the end... But it was good that this would be fine. Without him, it would save a lot of trouble.

Just as Li Mu turned around and was about to announce the elimination, a shout suddenly came: "Brother, we are here!"

Li Mu heard it was Li Chongyi's voice. When he looked back, he saw Changsun Chong limping step by step with Li Chongyi's support. Although half of his body was leaning against Li Chongyi, he was indeed walking with his feet. His expression had been twisted into a ball, as if he was exhausted, and he was completely dominated by his willpower.

At this moment, Li Mu was actually a little moved.
