"It's only been five minutes, and while it won't take long to try for the first attempt, every adult knight under my command can do it for at least an hour."

Artoria's reminder sounded in her ears, "Itachi, although you are a child, since you have been on the battlefield and can persist in that kind of long journey, it should be no problem to do it for half an hour for the first time." ”

Just...... Has only five minutes passed?

Hiss –

With his eyes closed, Itachi had never felt that it was so difficult to control his breathing.

It's like holding a breath, and you can exhale normally at one time, but you have to divide it into ten small parts, or even twenty small parts, and thirty small parts to exhale the turbid breath slowly.

It's like inhaling, you can inhale enough oxygen at one time, but you have to inhale it many times, little by little, and feel the breath entering the lungs along the throat, so that ventilation, ventilation, and gas transmission in the blood......

This type of breathing, if it is only done once or twice, is not too difficult.

But if you take 10 or 100 breaths, or even if you always maintain and control the rhythm of your breathing, then this difficulty becomes extremely painful.

Especially when the qi and blood in the body become faster and faster with the rhythm of breathing, an indescribable pain occupies Itachi's heart.

But this pain is not physical pain.

It's mental torture.

Feeling of bloating, retching, wheezing, and even ...... abandon

In the dark vision, all kinds of distracting thoughts unconsciously surged into Itachi's mind.

He wanted to stop his movements, he wanted to stop controlling his breathing, he wanted to stop controlling the flow of qi and blood, and even his body trembled unconsciously.

Even in my mind, I have begun to imagine that after I start and stop, I can breathe freely, I can stand up straight, and I can lie on the lawn in large characters......

But unfortunately, not yet.

As Artoria said, this is not only a physical exercise, but also a spiritual and mental exercise.

At the same time, in this process, it seems that I can feel the physical energy and drive it in more detail.

Although this level of improvement was very weak, Itachi still really felt the change, and his heart that was originally full of distractions suddenly calmed down.

Compared to the endless torture and darkness, as long as he can see a little bit of light and a little reward, he firmly believes that he can persevere.

"It's been ten minutes."

Artoria's voice rang out again.

And this time, her voice didn't affect Itachi's mind anymore.

"Fifteen minutes ......"

"Twenty minutes ......"

Almost every five minutes, she speaks.

And as time goes by,

Beads of sweat slid down on Itachi's body like water, wetting a large area of the ground.

Then, the moist earth is gradually evaporated and rises with the blazing sun.

At this time, the body of the weasel was no longer as white as before, but was dyed with a faint layer of pink.

The agitated qi and blood were rushing in his body, and the speed of his flow was even more enthusiastic than when he was running and hurrying before.

And this enthusiasm was like beads of sweat falling on the hot ground, turning into mist and slowly rising from him.

Under the sun,

Itachi's whole person is as if he is in a misty bathroom, wrapped in mist, looming.

"Thirty minutes is up, you can stop."

Artoria rose from the stump, her eyes full of appreciation.

"I think...... I haven't reached my limit yet. ”

But Itachi's voice reached her ears through the voice of her heart, "If a knight under your command is normal to persist in this kind of tempering for an hour, I can do it." ”

"But they are knights who have grown into adults."

Artoria kindly reminded, "And although your body is stronger than that of a normal child, you ...... After all, it has not yet reached the optimal stage. ”

"I can."

Itachi persisted.

Artoria didn't stop her, but sat back on the stump, staring at the tiny body with her eyes intrinsic.

For the rest of the day, Artoria didn't say the time again, and Itachi didn't ask.

Until he couldn't hold on anymore, he felt the water in his body, the loss of qi and blood, muscle endurance, and so on...... When the state has reached a peak, it stops moving.

"It's one hundred and thirty-five minutes in total, which is very good, more than two hours."

Artoria once again raised her opinion of the ferret's tenacity.

Soon, though, she jerked to her feet from the stump.

For Itachi did not answer her, but stumbled like a man who had lost his mind, moving in an unknown direction.

"Too extreme?!"

Artoria quickly realizes the conditions she has ignored.

Itachi is not himself, he has no dragon blood in his body, no body as strong as himself, and no strong recovery power like a dragon!

And just when Artoria realized her mistake, the Itachi was already pulling on her tired body, which was a little uncontrollable to even walk, and moved towards the stream little by little.

Chapped lips like the earth after a drought, parched throat like a dry well, not to mention a body that is so hot that it looks like a high fever and a stomach that is so hungry that it is stomach acid.

Itachi is well aware that he needs ...... now

Whoop -

With the sound of splashing, the weasel's body crawled into the stream, which was only thigh-high in height.

"Wait......"

Artoria, with a worried face on her face, followed him with a slight hurry, trying to stop him from falling into the stream.

Unfortunately, she was just a spirit and couldn't touch Itachi's body.

Gurgling ......

Regardless of whether the water was clean or not, the weasel gulped into its mouth after falling into the stream.

Even from time to time, he directly grabbed the shrimp and threw it into his mouth.

Itachi knew that at this time, he had to replenish the lost energy as soon as possible, and he had to lower his body temperature.

When exercising, the temperature of one's body rises because under the tempering method, qi and blood promote the rapid operation of various organs in the body at the same time to achieve a relative balance.

Although its temperature is high, the body can adapt, can be discharged, and can be adjusted.

And now that it has withdrawn from that high-intensity operating state, such a high temperature will cause some damage to the body if it is not lowered as soon as possible.

Looking at the Itachi, which was calming down in the stream and slowly adjusting itself, Artoria stood by the stream and breathed a sigh of relief, "As the first time, your cultivation is a little too extreme. ”

"You've almost lost your mind, and that's dangerous."

"I can't help you as a spirit, and there is no one else around, so if you lose consciousness, there will be no one to help you."

Feeling the cold water gradually lowering its temperature, the weasel lay down in the stream and calmly replied, "I know it in my heart. ”

He now believed that Artoria had no teaching experience before that.

However, Itachi is not worried about this.

Although Artoria had no experience instructing others in their practice, she was able to control this measure herself.

My own body, I don't know where the limit is better than myself.

The situation just now, although it seems to be a crisis.

But Itachi knew very well that his mind was not chaotic, but extremely calm.
