God-level Add-on

I don't know how long it took, and the noisy voice in the classroom gradually quieted down.

Not only that, Tang Duo even heard some words such as "Old Nie is here, stop talking".

Soon, the noise in the classroom gradually turned into the sound of reading aloud.

This change of spirit suddenly made Tang Duo feel like he was laughing dumbly.

It's a long-lost familiarity!

Old Nie......

After searching in his mind, Dondo suddenly recalled.

This teacher, known as "Old Nie", whose real name is Nie Tianyou, is actually the head teacher of Class 18 of Senior One, who mainly teaches Introduction to Martial Arts.

It is said that he once went to the battlefield, killed the enemy and made meritorious deeds. Later, he retired from the second-line army due to injury and became a teacher.

But even if he became a teacher, he still carried a trace of the iron-blooded style of a soldier.

This also caused the students in the class to be extremely afraid of the teacher.

After Lao Nie entered the classroom, his eyes flickered obviously when he saw Tang Duo was there.

He actually knew something about Tang Duo's injury.

I didn't expect Tang Duo to recover so quickly.

This surprised Old Nie a little!

It stands to reason that Tang Duo's physical fitness is not so good. Did he take some good medicine?

But according to the financial resources and connections of the Tang family, there should be no channel to start a good medicine pill... Strange!

However, these thoughts were only fleeting, and Lao Nie immediately opened the textbook.

"At the beginning of the class, everyone turned to page 86 of the textbook. Today we will talk about the relationship between "muscles, breathing, oxygen, energy, qi and blood"..."

Perhaps it used to be a military relationship, and Lao Nie's voice was eloquent and powerful.

Even if Tang Duo was sitting in the second-to-last row by the window, he could still hear it very clearly.

Along with Lao Nie's narration, Tang Duo even had an eye-opening feeling.

It is worthy of the high martial arts world where Kewu established the country, and the students of the first year of high school have been exposed to these.

If you put it in the previous life, unless you are a medical student, you will not be able to get in touch.

Human exercise needs to consume a lot of energy, and the energy source is mainly provided by the aerobic decomposition of carbohydrates.

Oxygen is the key substance for human metabolism and the first need for human activities.

The oxygen in the breath is converted into oxygen available in the human body, which is called "blood oxygen".

The higher the blood oxygen content, the faster a person's metabolism, which can provide more energy in a short period of time.

Through special breathing techniques, martial artists can draw a large amount of oxygen in a short period of time, thereby obtaining higher bursts and longer lasting stamina.

When Old Nie talked about this, Tang Duo's mind suddenly appeared one after another of memory fragments. Since elementary school, the school has taught basic breathing techniques.

Every time after a lot of exercise, the teacher does not let the students sit down immediately, but emphasizes adjusting their breathing over and over again.

From practice to theory, from knowing it to knowing why...

The students of this world have actually learned a lot of martial arts knowledge from their ears and eyes.

Think about it too, the inheritance of knowledge must be from easy to difficult, layer by layer.

It's impossible to wait until after Tang Duo's time-travel, the college entrance examination is about to take place, and everyone starts to "surprise study" together.

Those are called interest classes, not compulsory courses.

Cultivating talents is a very rigorous job, and cultivating people in a century is not a joke.

When one is focused on something, time always flies.

Before he knew it, Lao Nie finished the course.

When the get out of class was about to end, Old Nie suddenly said, "Everyone must want to apply for martial arts, after all, the social atmosphere is like this. But what the teacher wants to say is that martial arts is not everyone's only choice. Choose any profession, you can make a difference contribute to society.”

"In the next two months, there will be a series of martial arts evaluations one after another. Those who pass will certainly fail, and there will even be far more failures than those who pass..."

After patrolling the class, Lao Nie continued, "It's gratifying to pass, but it's no big deal to fail. I hope everyone can view it rationally and don't make some extreme choices..."

As soon as Old Nie finished speaking, Tang Duo felt like he was sitting on pins and needles.

Although Old Nie didn't take his seat, all the classmates still cast their eyes on him.

Tang Duo was helpless.

It seems that his label of "arrears in IQ" and "addicted to counterfeit drugs" cannot be removed in a short period of time.

Blue skinny mushrooms!

......

The curriculum of this school is completely different from that of Dondo's previous life.

In a previous life, the physical education teacher was either sick or on the way to being sick.
