"Empty bottles hit people by superficial contact, for example, if the bottom of the bottle hits you, the body and cap of the bottle will not be able to exert an offensive effect."

"In the same way, brute force hitting people can only be limited to fists and feet, and a punch is the power of a punch, and it is impossible to bring the strength of both feet."

"Internal force is like a bottle full of water, even if only the bottom of the bottle touches you, you are also exposed to the force contained in all the water in the bottle."

"Moreover, the force contained in water can penetrate the skin and act directly on the subcutaneous tissues and organs, forming so-called internal injuries."

"In other words, people who have mastered internal force can exert the greatest power in every move, even if it is just a finger poking you, it will produce the lethality of both fists and feet combined."

This is not Xi Tong's perception, but the martial arts knowledge of the future world. Bottles and water are the most commonly used paradigms in the future world, and they are the first lesson that almost all human beings must take when they come into contact with martial arts.

At this time, someone asked: "Coach Xi, are the strong internal forces also divided into beans, beans, beans, and beans?" ”

Xi Tong almost burst out laughing, and hurriedly explained: "Everyone has heard the phrase 'the development of the human brain is only 10%'. ”

Everyone nodded one after another, but no one spoke, all of them stared at Xi Tong with wide eyes, listening to him preach and teach.

"The potential of the human body has not been fully developed, and if you are a weak chicken otaku, you can probably exert 5% of your potential, that is, the five scum of war. The sub-healthy population is about 5% to 10%. ”

"If you exercise for a long time and get some results, you can maybe reach 30% or even 40%. Some of the maniacs who focus on martial arts training can exceed 50 percent, and the best of them, such as Bruce Lee, can reach 70 percent, 80 percent, or even higher. ”

"The purpose of cultivation is to improve comprehensively and promote the evolution of the essence of life, not just to train the chest muscles and abdominal muscles."

"It's like the barrel principle, it's the shortest board that determines your overall level, not the longest."

"If you awaken all your potential, accurately control every bone and muscle in your body, and move your whole body with one shot, and you can exert 100% of your strength with every move, then congratulations on becoming a bean and officially embarking on the path of cultivation!"

it!

The students were not calm anymore.

Dig your physical strength to the limit and exert 100% of your strength with every move, this is clearly a superhero, but in the eyes of Coach Xi, he is just a bean.

Without waiting for the students to continue to ask, Xi Tong waved his hand, "Keep practicing!" If you practice your blood well, your internal force will come naturally. ”

After hearing this, everyone was excited, and burst out with enthusiasm and fighting spirit. Because they believe that Coach Xi will not be untargeted, and the enthusiasm and internal strength must have the relationship between brother-in-law and sister-in-law.

In Xi Tong's view, the blood boiling really has a trace of internal force.

After the blood boils, the blood is surging all over the body, all parts of the body are congested, and the potential energy of blood will be carried in the punches and kicks, just like a bottle filled with water, and the punches and kicks have additional lethality.

However, there is a fatal disadvantage of blood boiling, that is, it cannot be used in a state of poisoning and bleeding, otherwise it will accelerate the spread of toxins and blood loss, and accelerate death.

But it doesn't matter!

The effect of blood boiling is so powerful that it is impossible to refuse.

The mere burning of fat makes everyone crazy, throwing off the fat of the body, the whole body is relaxed, the steps become neat, and the body becomes lighter, as if practicing light exercises.

In addition, the life energy generated by burning fat will nourish the body, promote growth and development, and although it is not as immediate as puberty, it will moisturize and silently improve physical fitness.

At the same time, cultivating the blood boiling is equivalent to refining and refining the qi, and of course, what is refined is the vitality of life.

Yuan Qi is formless and substantial, it neither wanders in the meridians nor is it stored in the acupuncture points, but is contained in the limbs and even the spiritual mind.

It can promote the evolution of living beings, and it can also help living beings to open up their talents and obtain mysterious powers, which is the original driving force of evolution, and it is also the first energy that all human beings must master in the future.

Just as Xi Tong was pondering, the door of the exercise room slammed open.

Xi Tong frowned, Yue Yang Yudie had promised that the venue provided for him was soundproof and private. How could anyone make trouble?

Looking up, a woman who was nearly 1.7 meters tall and wearing a black tight bodybuilding suit walked into the exercise room.

She patted the non-existent dust on her hands, and her squinted eyes swept around the room to lock onto Xi Tong.

"You robbed me of my territory?"

Xi Tong's eyes are confused, what do you mean?

A student behind him whispered: "Coach Xi, she is Coach Chen Xi who teaches gymnastics and various dance classes, and has been teaching here for more than two years." ”

"She is said to be a dancesport athlete in the government and has also participated in the Olympics, although only as a substitute."

"When Coach Chen first came to the club, a coach wanted to tease her, but she was beaten and her nose and face were swollen."

Xi Tong's first reaction: Shouldn't it be Luo Rui's unlucky child who teased her?

I asked, and I was beaten up as a humanoid sandbag.

A few of the students who had seen the battle immediately spoke eloquently.

"Although Coach Luo is not tall, his strength is absolutely strong and he has nothing to say, and he insists on playing iron every day, and his muscles are comparable to steel ingots. As a result, Coach Chen Xi beat him like a child. ”

"Coach Chen Xi is dancing, his body is flexible, his speed is fast, according to the game, he is an assassin of Quan Min, just to restrain Coach Luo's pure strength."

"That day, Coach Luo was like a bull, constantly rampage, Coach Chen just gently turned sideways, and then raised his foot and kicked, Coach Luo fell so much that he gnawed on, fell more than a dozen times in a row, and Coach Luo simply lay on the ground and couldn't get up."

Xi Tong was amazed, he didn't expect this woman to be able to eat by her strength, skills or looks, and she was well-fed and well-fed.

This is definitely not the average person!

After becoming cautious, Xi Tong observed more and more carefully.

He found that when Chen Xi walked, his feet, wrists, legs, waist, back, shoulders, neck and other parts were all linked in an orderly manner, as if there was a ripple rippling from his heel to the top of his head.

The amplitude of this ripple is so slight that ordinary people can't see the details at all.

But Xi told him that this is a sign of body coordination, and only someone who has a precise grasp of every part of the body can do it.

Just as Xi Tong was carefully observing, Chen Xi stood two meters in front of him, not shaking, not advancing, as if she had been there all along.

From movement to stillness, it is just a time to breathe, and the two different temperaments of weak willow Fufeng and Yuanyu Yuezhi are perfectly integrated in her body, and they can be transformed at will.

Then, an invisible momentum centered on Chen Xi spread and spread around, enveloping Xi Tong in the blink of an eye.
