This Uchiha Itachi is very lonely

"Only five minutes have passed. Although it doesn't take long to try it for the first time, every adult knight who has ever served under me can do it for at least an hour."

Arturia's reminder sounded in her ears, "Itachi, although you are only a child, but since you have been on the battlefield and can persevere on such a long journey, you should have no problem doing it for half an hour the first time. "

Only...only five minutes have passed?

hiss--

Closing his eyes tightly, Itachi had never felt that controlling his breathing was such a difficult thing.

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

Just like inhaling, you can obviously inhale enough oxygen at one time, but you have to divide it into multiple times, inhale little by little, and feel the breath entering the lungs along the throat, so as to ventilate and exchange the gas. Transmitted in the blood...

If you only perform this breathing method once or twice, it will not be too difficult.

But if you take ten or a hundred breaths, or even maintain and control the breathing rhythm all the time, then this difficulty becomes extremely painful.

Especially when the energy and blood in the body became faster and faster with the rhythm of breathing, an unspeakable pain occupied Itachi's heart.

But this pain is not physical pain.

It's mental torture.

Feelings of bloating, retching, wheezing and even...giving up,

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

He wanted to stop moving, he wanted to stop controlling his breathing, he wanted to stop controlling the flow of qi and blood, and even his body began to tremble unconsciously.

Even in my mind, I have begun to imagine that after stopping, I can breathe freely, stand up straight, and lie on the lawn with a big letter...

But unfortunately, it's not possible yet.

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

At the same time, in this process, I seem to be able to feel the physical energy and drive it in more detail.

Although this level of improvement was very weak, Itachi still felt this change, and his heart, which was originally full of distracting thoughts, suddenly calmed down.

Compared with 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 sounded again.

But this time, her voice did not affect Itachi's mind.

"Fifteen minutes..."

"Twenty minutes..."

Almost every five minutes, she would make a sound.

And as time passes bit by bit,

Sweat beads slid down Itachi's body like water, soaking a large area of ​​the ground.

Then, the moist land was gradually evaporated and lifted up along with the hot sunlight.

At this time, Itachi's body was no longer white as before, but was dyed with a light pink color.

The qi and blood were rushing through his body, and the speed of its flow was more intense than before when he was running or on the road.

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

under the sun,

Itachi's whole body seemed to be in a mist-filled bathroom, wrapped in mist, looming.

"Thirty minutes are up, you can stop."

Arturia stood up from the tree stump, her eyes filled with admiration.

"I feel...I haven't reached my limit yet."

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

"But they are adult knights."

Artoria reminded her kindly, "Although your body is stronger than that of a normal child,... after all, it has not reached its optimal stage yet."

"I can do that."

Itachi persisted.

In response, Artoria did not stop her, but sat back on the tree stump again, staring straight at the small body.

In the following time, Artoria did not tell the time again, and Itachi did not ask.

It wasn't until he couldn't hold on anymore and felt that the water content in his body, the loss of energy and blood, the endurance of the muscles, etc... had reached a peak, that he stopped.

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

Artoria once again raised her evaluation of Itachi's tenacity.

But soon, she suddenly stood up from the tree stump.

Because Itachi didn't answer her, instead he stumbled and moved in an unknown direction like a man who had lost his mind.

"Is it too extreme?!"

Arturia quickly realized the condition she had overlooked.

Itachi is not himself, he does not have dragon blood in his body, he does not have a body as strong as his own, and he does not have the powerful recovery power like a dragon!

And just when Arturia realized her mistake, Itachi had already pulled his body, which was so exhausted that it was difficult to control even his steps, to move bit by bit towards the stream.

His chapped lips were like the earth after a drought, and his dry throat was like a dry well. In addition, not to mention his body that was as hot as a high fever and his stomach that was so hungry that his stomach acid was churning.

Itachi knew very well what he needed now...

Wow——

Accompanied by the sound of splashing water, Itachi's body climbed into the stream that was only as high as his thighs.

"etc……"

Arturia, whose face was full of worry, followed him slightly hastily, trying to prevent him from falling into the stream.

But unfortunately, she is only a spirit body and cannot touch Itachi's body.

Gulu gulu gulu...

Not caring whether the water in the stream was clean or not, the ferret poured it into his mouth after falling into the stream.

From time to time, he would even grab small shrimps and throw them into his mouth.

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

During exercise, your body temperature rises because under the exercise method, qi and blood prompt various organs of the body to operate rapidly at the same time to achieve a relative balance.

Although the temperature is high, the body can adapt to it, discharge it, and adjust it.

Now that it has exited that high-intensity operating state, if such a high temperature is not lowered as soon as possible, it will cause certain damage to the body.

Looking at Itachi who was calming down in the stream and slowly adjusting himself, Artoria stood by the stream and breathed a sigh of relief, "This is your first time, so your practice is a bit too extreme."

"You almost lost your mind, and this situation is very dangerous."

"As a spirit, I cannot help you, and there is no one else nearby. If you lose consciousness, no one will be able to help you."

Feeling the cold water gradually lowering his temperature, Itachi lay in the stream and calmly replied: "I know what I know."

He now believes that Artoria really had no teaching experience before this.

However, Itachi was not worried about this.

Although Artoria has no experience in guiding others to practice, she can control this measure well.

No one knows where the limits are better than your own body.

Although the situation just now seemed to be a crisis.

But Itachi knew very well that his mind was not actually confused, but rather extremely calm.
