"Everything has its own rules, such as the swallow flying south in autumn."

"Why is it autumn, not spring or summer, and that's the rule."

"The same people have their own laws, and what kind of laws do long-lived people have, and this is health preservation."

......

In the academy on the outskirts of Chang'an, Shu An continued to lecture on his own, albeit as a new course.

But it was quickly accepted by these students, even if it was the most irritable Cheng Zhiliang and a few people were very serious on their faces.

This shows the charm of health care, and you must know that even teenagers are like this, let alone those who are getting older.

For these people, health preservation is like a straw in life, although it does not reach the level of life-saving, but it is certainly an indispensable part.

"What I want to teach you today is a health boxing method, which was also created by me."

Shu An said with a smile on his face, this boxing method is adapted from the system, and its role is needless to say.

If you practice every day, Shu An can feel a lot of energy, and from now on, it will also be an indispensable part of these teenagers.

As the words fell, the faces of the students present couldn't help but show a trace of doubt, as if they didn't know that this dean could also box.

With a half-believing attitude, these students couldn't help but follow Shu An out of the room and into the playground.

"Chu Liang, you come up and make a demonstration."

Shu An's eyes fell on Cheng Chuliang and said loudly, the reason why he chose Cheng Chuliang was naturally because of his rough skin and thick flesh.

"Me?!"

Cheng Chuliang said with a hint of doubt on his face, but immediately reacted.

"Although it is a health boxing method, if there is a fist word, then it still has some lethality."

After Shu An saw Cheng Chuliang standing in front of him, he slowly said in a loud voice, you must know that after getting the Immortal Fist, he is already a master in boxing.

Although the system has instilled a lot of experience in him, he has not tried it in actual combat, and now Shu An has found Cheng Chuliang.

"Wait a minute, you attack me first."

Shu An's voice sounded slowly, but this sentence made Cheng Chuliang's face a little panicked, and some at a loss.

"Dean, if I attack you and go back, my father will definitely kill me."

Cheng Chuliang shook his head desperately and said loudly, you must know that this dean is well-known all over the world, if others know that he is attacking the dean, then he will definitely denounce himself.

After thinking of this possibility, even Cheng Chuliang couldn't help but shudder, he couldn't shoot anyway.

"It's okay, this is just normal teaching, if you don't make a move, then you will fail this month's assessment."

Shu An's complexion did not change at all, but he said with a hint of teasing.

For the respect of these students, Shu An knew that it was more of a role brought by fame, and in fact, he did not teach a few classes.

"What, fail the assessment, no!"

"Dean, isn't there really a problem?"

Cheng Chuliang was taken aback by Shu An's words, knowing that if he failed the assessment, he would be expelled from the academy.

If it had been more than a month ago, he would have been elated, but now he was used to the food and classes of the academy.

Cheng Chuliang naturally didn't want to be expelled from the academy, and how to choose Cheng Chuliang naturally made a decision, but there was still a trace of hesitation on his face.

The other students couldn't help but feel a little glad when they saw Cheng Chuliang's embarrassed face, but fortunately the dean didn't call him.

"There won't be any problems, let's do it."

Shu An said with a hint of amusement on his face, does he look so weak.

You must know that because of the food, Shu An still has a lot of strength, even on the battlefield, Shu An has the confidence to fight a few enemies.

Of course, he is destined not to have this opportunity, so he can only take advantage of the current opportunity to get over with these students.

Not everyone is Xue Rengui, such as Cheng Chuliang, who was born in the general's door, although he has practiced martial arts since he was a child, his talent is not too high.

In addition, he is not very tall, and he is shorter than Shu An, so Shu An can't help but sigh in his heart, is he being underestimated like this.

"Dean, then I'm attacking!"

Cheng Chuliang hesitated for a long time and then said out loud, he was already secretly thinking in his heart whether he wanted to be more waterproof.

"Let's get started!"

Shu An nodded in response, and then made a defensive gesture.

Although there are some gray hairs, the sharpness in the eyes still makes people dare not look directly, this is the momentum of the boxing master.

It was just a defensive posture, but it still made some doorways on the faces of these children who were born in the sect.

"Sasa!"

Cheng Chuliang also gritted his teeth at this time, and shot out with a straight punch, bringing up a fist wind.

It's just that Shu An's eyes didn't change at all, and he shook his head in his heart, perhaps due to the influence of his identity, Cheng Chuliang obviously didn't go all out, but had a lot of water release.

As a result, in Shu An's eyes, Cheng Chuliang was full of flaws, and without any hesitation, Shu An stepped forward directly.

The figure tilted slightly to dodge this punch, and then the punch that had been prepared for a long time burst out, and the force that burst out by the way.

Bang!

A collision sounded, and Cheng Chuliang's complexion changed, and he took three steps backwards to stabilize his pace.

It was only a brief collision, but it made some surprise on the faces of the other students, as the dean seemed to be as they had imagined.

Especially Cheng Chuliang, one of the parties involved, the force of this punch made the qi and blood in his body roll a little, and it was not easy to calm down.

However, with a trace of strange emotions on his face, the dean did not seem to be an old man, but a master who had practiced martial arts for many years.

It's just this reaction, even if it's under his own release, it's not comparable to ordinary people, which can't help but make Cheng Chuliang feel some frustration.

At this time, it was not only these students, but Su Lie, who was standing on the side, also showed a hint of surprise on his face.

He never knew that his master still had this hand, which was simply unexpected, especially with a simple punch, he saw a trace of fist intent.

You must know that it is impossible to have a level without practicing boxing for decades, but your teacher still has this one to practice boxing.
