Four Hundred and Fifty-Three. In Practice [1]

( ) Naruto followed Jilai and went out to practice. Everyone was not willing to lag behind and practiced desperately, and Mizuki naturally couldn't slack off either.

Fortunately, Tsunade did not break his promise this time, and took a little time to personally guide Mizuki: "Starting today, I will personally guide you, but I hope you have enough mental preparation, because spiritual practice is very hard!"

Of course there was preparation for this, Mizuki nodded naturally and agreed: "Well, I will definitely practice hard."

Shuishu has this confidence. One must know that physical training is the most difficult and tiring kind. When he was young, he broke his bones more than once in order to practice, and he is already used to it.

Seeing Mizuki's statement and the spontaneity on his face, Tsunade nodded in satisfaction: "Very well, then, the next step is to start practicing! I know that you specialize in strength, which is very similar to me. Let me show you first."

"Yes!" Mizuki nodded in understanding.

She came to the front of a rock, closed her eyes and took a deep breath, and within a breath, her fists were like lightning.

With a bang, the rock was blown apart and shattered into stones and debris on the spot.

Seeing the scene of the earth and rocks splashing, Tsunade nodded in agreement: "It is very powerful. Without using Chakra, the power of the fist can shatter rocks."

Breaking rocks with his own fists, in fact, Shuishu could easily do it very early. Moreover, many ninjas who value physical training almost all have such abilities.

However, Mizuki didn't use Chakra here, it was completely spliced ​​with his own brute force, and he was able to achieve such a step, which is still very good.

Mizuki is very confident in himself: "Master Tsunade, although I am not good at ninjutsu and illusion, I dare say that in terms of strength, I can be called the number one!"

Excellent physical fitness and strong strength are the pride of Mizuki, because with these two abilities alone, even if she encounters many Jonin, she will not be at a disadvantage.

Tsunade expressed his affirmation on this point: "It is indeed very good. If you only look at it from the perspective of strength, the average Jonin is really not your opponent."

Of course, the rating is very high, but here is a quick, said that there is a problem.

Tsunade said: "You are using brute force without the slightest striking skills. You can see that the gravel on the ground is scattered, starting from the place where your fist hit, it is obviously a sputtering shape.

Can you spot something? "

Hearing Tsunade's instructions, Mizuki looked at the sputter-like branch of the gravel, which showed a 180-degree fan shape, which looked like his own fist, and the shock wave he hit was powerful.

Seeing such a situation, Mizuki couldn't understand: "Is there anything strange about this? The broken stones are splashing everywhere."

After listening to the question in Mizuki's words, Tsunade pointed out the question: "You are right, the shattered rock will definitely splash everywhere. But where does the power come from? It is not your bombarding fist!"

"That's right, your fist is very powerful, and when you hit it, it's very powerful. But have you noticed that when your fist hits the target, the power actually spreads out? The flying gravel, It is the state of being beaten out by your power."

What's so strange about this? When the power is released, it is no longer controlled by the human body, and there is a scattering effect, isn't it normal?

Mizuki touched his chin with one hand, subconsciously meditating. According to her understanding, the more powerful her fist is, the faster she can punch it out, because the friction between the fist and the air creates a more intense shock wave.

Tsunade didn't think of Mizuki at this time, and didn't figure out why, so she tapped her on the head: "You are really smart and confused for a while. To put it simply, your fists are very powerful, but they don't focus on together, causing the diffusion and waste of power."

In order to make a better explanation, Tsunade himself also found a rock, and punched it out with a strange force. Without any problem, the whole rock was shattered.

However, this is different from the splitting of the water tree, but the crack where the fist was hit, that is to say, the power from the fist was punched in without any mistakes!

This was in stark contrast to Mizuki's attack, which made her notice: "My fist is very powerful, but it's not concentrated?"

Mizuki thought carefully again, and remembered that he used his fists to create shock waves, as if he was training the Raptors to exaggerate. Because it refers to the Bamen Dunjia, the pressure attack it makes is associated with the "sound barrier" problem of the aircraft.

When the plane is about to enter the speed of sound, the problem of the shock wave will become more and more serious, but as long as the shock wave is broken, supersonic cruise can be carried out.

But it is definitely unrealistic to compare an airplane with a human body, because all modern supersonic airplanes have rocket propulsion, and my own fist does not have such a thing.

Seeing that she was at a loss, Tsunade gave a path: "Have you seen bows and arrows? Bows and arrows can penetrate fine armor just by using the elasticity of the bowstring."

Do bows and arrows penetrate armor? The water tree is not particularly clear about the specific details. But I also understand that until the appearance of plate armor, bows and arrows can easily penetrate any armor within the effective range.

It should be the mass, speed and inertia, a series of factors, right? Shuishu is not very clear about this point, because there is no relevant knowledge reserve.

But looking at Tsunade's masterpiece, the rock cracked from the place where it was hit, which is somewhat similar to this kind of penetration. Mizuki began to think again: "If I want to achieve such an effect, the removal force must be strong enough and fast enough!"

Mizuki began to try, closed his eyes and breathed flatly, adjusting his state. Then, at the moment of lightning, he hit another rock with his fist. There was no hindrance to the fist, and it hit it directly, and the whole rock collapsed and shattered,

Seeing Mizuki's punch, Tsunade nodded with a smile: "Yes, your understanding is very high, but the power of the fist here is still too scattered."

The cultivation of physical skills requires practice over and over again, and finally reaches the point where practice makes perfect.

Soon Mizuki gradually realized a little bit: "Explode! If you punch from the beginning, the shock wave formed will inevitably spread the power, but if you release all the power at the moment of hitting the target, you will It will form a very strong penetration."
