After running for two kilometers, Yu Shan walked into the classroom without blushing and without a heartbeat, and at this time he could clearly feel the internal qi in his body.

Along the way, all the heat generated in his body was turned into internal qi by him and stored in the dantian, so at this time, Yu Shan felt that his lower abdomen was warm.

Although it was the first time he had a sense of qi, Yu Shan just knew that the warm position in the center of the lower abdomen should be the dantian qi sea.

Faith is indeed very important, and it is because of Qian Xiaohao's words that Yu Shanshun felt a sense of qi, which is no longer comparable to a set of Five Emperor Money.

Therefore, even if he was despised by Qian Kaiyuan, even if he was disliked, Yu Shan did not feel ashamed at all, he always firmly believed that what suited him was the best.

Maybe Qian Xiaohao's inheritance is easier to learn, maybe it's a shortcut to the south, but it's not necessarily suitable for Yu Shan, so Yu Shan is excited and happy at this time.

Sitting in the classroom, Yu Shan was like a child who had just gotten a treasure, constantly realizing the heat flow in his body, which is the legendary internal force.

How to generate internal force, how to store internal force, and how to enhance internal force are all things that Yu Shan urgently needs to understand.

"What are you doing? Either giggling in the morning, or staring at me, I got sick without taking medicine? A little beauty with a ponytail, a short-sleeved shirt and shorts, revealing a white beauty, looked at her tablemate.

Yu Shan stared at the Qianqianyu hand holding the pen, this little hand has ten fingers, white as jade, the nails are round, and the white is red, which is very attractive to look at.

"Can't see it? I'm practicing! Yu Shan replied without hesitation.

"Inextricably linked to the ** skill?" Zhang Jingya said sarcastically.

Looking at the jade hand playing with the ballpoint pen, Yu Shan said seriously: "Jiuyang Divine Skill." ”

"I'm bored, just lie down and sleep if you're fine, or read your martial arts novels, don't always stare at my hands, I don't know and think you're a pervert!" Zhang Jingya turned her head and looked at the teacher in front of her again, and if she said anything more, she would be targeted by the old class.

Feeling that the head teacher's gaze swept over again, Yu Shan didn't dare to go too far, so he had to withdraw his gaze on the jade hand, even if the head teacher generally didn't care about him, but he couldn't go too far.

Feeling a little bored, Yu Shan lay on the table, his chin resting on his hands, and looked at the head teacher in front of the blackboard.

"It's my third year of high school this year, and I'm going to college next semester!" Yu Shan was a little emotional.

Although he was staring at the old class, his mind was not on studying.

Originally, his sports performance was very good, so Yu Shan didn't like to study too much, anyway, with his ability, he couldn't starve to death.

Now, Yu Shan doesn't think like this, maybe he can achieve more, and this requires him to study more internal strength.

Yu Shan stared at Zhang Jingya's little hand again, looking at this beautiful little hand, a warm current naturally appeared in his dantian.

Of course, Yu Shan knew why there was such a reaction, and this could only be said to be a normal reaction.

Of course, it is better to observe a pair of ** below, or the sensitive parts of the upper body, but Yu Shan didn't dare, so he could only stare at Zhang Jingya's hand.

That hand is indeed beautiful, as long as he looks at it, his dantian will be a little hot, and this is what he wants, so cultivating Jiuyang Divine Skill is not a lie to Zhang Jingya.

What is internal strength, this has always been debated, some people say that it is nothing, some people say that there is a nose and eyes, as if they will also.

Now Yu Shan knows that internal strength does exist, but it is not as magical as people say, internal strength, which can also be said to be qigong, is just practicing qi.

Of course, this Qi practice here is not a cultivation of truth, it is just a technique of breathing and breathing, to put it bluntly, it is to regulate people's breathing.

Someone is about to ask, what is there to regulate breathing? Can regulating the breath produce internal qi?

In fact, all exercise needs to regulate breathing, and it also needs to be regulated.

To put it simply, running, especially long-distance running, if you can't adjust the breathing rhythm, or can't regulate your breathing, then you will definitely not be able to run fast, and even if you run down, you will definitely be tired like a dying old cow.

Therefore, it is necessary to regulate breathing, and the ancients developed this regulation to the extreme, and even combined it with health preservation and fighting.

Yu Shan's cultivation of internal strength is naturally for health preservation and fighting, of course, it must also be a personal interest, if there is no interest, it is impossible to persist for so many years.

Seventeen-year-old boy, you can't ask too much of him, Yu Shan just wants to cultivate internal strength, punch the three tyrants on campus, kick the pseudo-men in the class, and dominate the third and second years of high school.

Today, Yu Shan felt that he was one step closer to his goal.

Every day he came to school, he had to run 12 kilometers, and this was six years.

From the beginning of the first day on the mountain, it has been persisting for six years now, and for six years, at least once a day.

In this process, it took less than 45 minutes from the beginning of three hours, which can be said to be a great improvement.

And the reason why there is such a big progress is that it relies on the breathing regulation method that Yu Shan learned from martial arts novels or various published qigong secret books.

In the past six years, Yu Shan has continuously experimented with the method of respiratory regulation, and finally achieved the best results.

The 12-kilometer journey can be broken down into three 12-minute runs, running down the whole course.

Every 12-minute run, Yu Shan has to run 4,000 meters, and three times down is 12,000 kilometers, that is, 12 kilometers.

The correct time is thirty-six minutes, and the other nine minutes require him to stop, regulate his breathing, and smooth his breathing.

You know, strenuous exercise causes the body to produce a lot of heat, and if you can't release this heat, your body will burn out and you won't be able to continue running.

Yu Shan's breathing regulation is aimed at these calories generated by strenuous exercise.

The consumption of human exercise, especially strenuous exercise, is very large, and the source of this part of the consumption is the part of the heat energy released by the body.

Yu Shan just started to use the regulation of breathing to quickly release this part of the heat energy out of the body, so that he could insist on running for 12 kilometers, but this took a longer time and consumed a lot more, and every time he finished running, he was tired like a dog.

And internal strength, or the method of breathing regulation, is to reduce consumption.

Energy is the primary support for the movement of all objects, and it is natural that the slower and less it is consumed, the better.

However, in human movement, a large amount of heat energy is always generated, and this heat must be quickly discharged from the body, otherwise it will burn the internal tissues of the human body.

Therefore, there is an article to be done here, and the internal power is to use the method of breathing regulation to recycle the part of the heat energy that was originally exhaled as much as possible, so that the consumption of the human body will naturally be reduced a lot.

It's an idealized idea, but it's not easy to really do it.

And this morning, when Yu Shan ran over, the heat generated inside his body was finally controlled by him and flowed to the dantian qi sea.

Originally, Yu Shan used breathing regulation to quickly dissipate this part of the heat out of the body, but now, he is storing the heat generated by exercise into the dantian qi sea, which not only reduces the heat of the body, but also preserves his strength.

In other words, after he ran down 12 kilometers, he did not waste much heat energy, and this part of the heat energy was retracted by him and continued to support him to exercise.

And when he kept adjusting the heat energy of the operation, Yu Shan felt a little different from usual.

Because he was too familiar with regulating the heat energy in his body, after a long time, Yu Shan was actually able to control the heat energy in his body and flow to his lower abdomen, making his lower abdomen warm.

This was too much of a surprise for a boy who was looking forward to internal strength, because Yu Shan knew that he really had a sense of qi and cultivated the first trace of internal strength.

Internal force, now Yu Shan thinks, is the energy in the body, and to put it simply, it is a special energy formed by refining the heat in the body.

In order to be real, there was an incident of staring at the jade hands of other people's little beauties.

When a man sees a beautiful woman, he naturally has to react, at least his blood is boiling, and his weakness is naturally a warm current in his lower abdomen.

What Yu Shan wants is this warm current, which produces a warm current, so naturally he has to test it to see if he can control this warm current and store it in the dantian.

"Barbarian, barbarian, what do you think? I heard you've awakened? would actually stare at Zhang Jingya? Just when the mountain god was not belonging, a thin boy woke him up.

"Skinny Monkey, what are you doing?" Yu Shan glanced at Pang Tong, this was his classmate, because he was thin and thin, he was called Skinny Monkey, and as for the barbarian, it was his nickname.

"Barbarian, you came a few minutes early today, how many times have you run in twelve minutes?" At this time, Zhang Jingya, Yu Shan's tablemate, spoke.

As for why the beauty spoke up first, she naturally didn't want Yu Shan to talk to Pang Tong about her topic.

"Four thousand meters." Yu Shan replied smoothly.

"Ahh Four thousand meters? Zhang Jingya opened her small mouth in surprise, the little mouth was red and gorgeous, revealing a small white tooth, which looked very cute.

"What a beast! Running in 12 minutes, you can actually run 4,000 meters? So how good is your cardiopulmonary breathing ability? The skinny monkey shouted in amazement that it was not human, beast or something, because it was really amazing.

Because of Yu Shan, people like Zhang Jingya and Pang Tong are very familiar with the twelve-minute run, which is entirely because they all know that Yu Shan has to run twelve kilometers to go to school every day.

"My results are not outstanding, but you are too weak." There is no smugness about this Yu Shan.

"You're comparing yourself to an athlete, aren't you? You're really immodest. Zhang Jingya said disdainfully.
