"The key to tempering is to be in control of oneself."

"The rhythm of the breath and the movements of the limbs are the key to promoting qi and blood."

"The danger of pushing qi and blood is that the tempering of the flesh when the qi and blood flow cannot exceed your own limit, otherwise the fragile body will not be able to withstand the impact of the surging qi and blood, and it will explode directly from the inside."

"And even if you have a good understanding of where your physical limits are, in the process, you may still feel difficult to breathe, and you will desperately want to breathe and give up."

"Please don't do this, if you give up your willpower before you stabilize your qi and blood, it will also pose a threat to your life."

"And in the process of tempering, the energy hidden in the flesh will be excavated, they will stimulate and strengthen your body, but at the same time, it will also be constantly consumed, and at this time, it will need to be replenished with medicine and food."

"No, no, no, these energies are not chakras, but the energies that exist in this world as a human being, such as physical strength, energy and even life force, the specific name, I haven't defined it yet......"

……

Although far away from the core area of Konoha and on the periphery of Konoha,

However, the land occupied by the Uchiha clan was indeed the same as Sarutobi had promised when he proposed their relocation, with a large area of forest that could be used to build a training ground.

And at this time, in the training ground near the Uchiha patriarch's mansion,

In front of Itachi stood eight mediocre-looking samurai and wrestlers who had a certain amount of exercise.

He is explaining the knowledge called the 'Tempering Method' in very serious and simple terms.

Compared to when Artoria instructed herself, she also taught and learned at the same time.

Itachi, as a person who has really learned and experienced this process, from the very beginning, told all the possible problems in the tempering process to the eight people in front of him, so that they could keep it in mind.

After all, if you can complete the learning of the tempering method in the first batch, you can save a lot of time.

However, this does not mean that Artoria is not suitable for being a teacher, but as the embodiment of the Red Dragon, she has never tried the tempering method, but has only mastered this knowledge.

Near them, Cangtian was sitting next to a group of Uchiha clansmen.

He also carefully recorded every word Itachi said, but compared to the Uchiha who opened the writing wheel eye next to him and recorded all the words and body movements of Itachi, there was only confusion and trance in his eyes.

The rhythm of the breath, Cangtian shirt can understand, isn't it just to control the frequency of breathing.

Those body movements may seem weird, but they are not difficult to do.

In this way, you can exercise your body and let ordinary people have the same strength as ninjas?

Is it the Uchiha Itachi kid who is playing with himself, or is it ...... Can't see the doorway yourself?

"Okay, let's try to practice."

But soon, Uchiha Itachi's words pulled Cangda out of that skeptical and confused mood.

Keeping an eye on the figures of the eight people on the training ground, he even blinked as fast as he could, so as not to miss any details.

"Let's try them one by one."

Itachi calmly looked at the few people in front of him, and finally set his eyes on a sturdy samurai, and the three-hooked jade in his eyes slowly opened, "One, you breathe according to the breath rhythm I just said." ”

"While feeling the qi and blood, breathe at the same time, and then through the body movements to match the rhythm of the breath, the qi and blood are pushed into the body, so that they are active and boiling."

"In this process, you have to ensure that your control over qi and blood cannot get out of control."

"Yes."

The samurai, who has been defined as 'No. 1', obeys unconditionally.

However, when he faced Uchiha Itachi's blood-red three-hooked jade, there was still a hint of envy in his eyes.

And next to him, several people who have been very calm since the first meeting also revealed various emotions when facing Uchiha Itachi's three-hooked jade writing wheel.

Those who chose to become samurai and wrestlers in such an era undoubtedly longed for power.

But in such an era, the inability to refine chakra means that it is an extremely luxurious thing to have power.

However, after all, they are carefully selected by the Daimyo's mansion, and based on their experience, they have extremely good control over their emotions.

Soon, they suppressed the envy, jealousy, and longing in their hearts...... , looking at the 'No. 1' next to him.

As a samurai, no matter whether 'Number One' can refine chakra or not, he has a certain foundation for his own control over his body.

In particular, qi and blood, meridians, and bones...... These words, maybe these noble officials only know the meaning of these words, but they have not personally felt them, but the 'No. 1' people are different.

As 'No. 1' closes his eyes and meditates.

On his body, after the frequency of his breath and the changes in his body movements unfolded, the people next to him could feel the faint change in the heat coming from his body, and even the sound of 'gurgling' qi and blood flowing.

I couldn't help but feel that the faces of the others gradually became serious.

They are all people who love martial arts and are good at martial arts, if they have the opportunity to have power, how can they not cherish it?

"How useful it is?!"

Cangtian sat far away and didn't feel the changes in 'No. 1', but he could clearly see from the details of other people's demeanors that 'No. 1' was indeed carrying out the so-called 'tempering'.

Involuntarily, Cangtian wanted to stand up and get closer to observe.

But as soon as he got up, he inexplicably felt several coldnesses coming from all directions.

Following the feeling, when Cangtian turned his head, he was faced with a pair of cold blood-red eyes around him.

"Ahem......"

With a dry cough, Cangtian smiled apologetically and quickly sat down again.

He almost forgot that the Uchiha Itachi had been strictly ordered not to disturb or approach before he made a request to observe.

As for Cangtian shirt's movements, Itachi didn't pay too much attention to it.

In addition to the Uchiha people who sat next to him to observe and study together, there was also a shinobi and several middle ninjas hidden near the training ground, always guarding the surroundings of the training ground.

Under this kind of battle, not many people in the ninja world can sneak into the training ground quietly.

"Good, keep it steady."

"Push the qi and blood to this place first, there is an extremely subtle meridian here, which is very fragile and requires more careful control."

"Follow the meridians, qi and blood can come to this point......"

The voice of the ferret continued to ring, in the ears of 'One'.

At the same time, he could also feel a finger swiping on his body, gently tapping at a certain point or a certain meridian to direct his direction of qi and blood flow.

At the same time, an irrepressible feeling of depression, suffocation, and exhaustion emanated from 'No. 1's body, eroding his spirit, thinking, and will like a virus.

It's like a dry well in the midst of a drought that is constantly being dug by hungry, thirsty and water-starved villagers, and it makes wails and screams.

But no matter how much you cry, a dry well is a dry well after all, and there is not a single water coming out.

"If you dig hard, you'll be able to dig out the water."

Itachi is the village chief who directs the people to dig water.

He was cold, ruthless, and convinced that his dry well would burst forth with more wonderful power.
