"Yiyong, do you have any questions about what I said?"

Ten minutes later, Uchiha Itachi stopped writing and drawing on the dirt flow wall with his shinobi knife.

Unlike when he first explained to Sasuke, he had to use many vivid and cute images as analogies.

Yiyong's comprehension ability is very strong, so Itachi directly introduced many special terms, and explained in detail the four processes of refining chakra and then transforming into pupil power.

The first step is to evenly mix the spiritual energy and physical energy in the body into [physical strength].

The second step is to convert [Stamina] into Chakra.

In the third step, the chakra made in the abdomen is transferred through the meridians to the internal organs for storage.

The fourth part, and finally, diverts the stored chakra to the chakra acupuncture points near the eyes as a reserve food for maintaining the chakra eye.

Sounds simple?

In fact, if you can skillfully complete the third step and let your chakra storage be enough to release two rounds of three-body techniques, you will have achieved the graduation conditions of the ninjutsu school of ninjutsu.

Most civilian graduates are at this level at the age of twelve, while those from families master these contents around the age of ten.

Geniuses such as Sasuke, it has been more than half a year since he extracted the chakra, and he has only just stepped into the threshold of the third step, so he can only store the chakra slightly, otherwise the fireball he blows out is not just as simple as lighting a candle.

[I just don't know how long it will take for Yiyong to use the writing wheel eye stably......]

[Perhaps, a year or so?] 】

"No problem for now."

Yiyong nodded earnestly.

Even if Uchiha Itachi didn't talk so much, he also used the [Transparent World] to take a look.

Now, after opening the transparency again, he can not only see the bones, muscles, and blood vessels of the human body, but also a complete set of chakra meridians and acupuncture points, and can accurately see the track and direction of the chakra flow of the other party, which naturally includes the entire process of its formation and transformation.

As everyone knows, even if Yi Yong does not open the blood inheritance limit, he only uses the innate [transparent world] to achieve the basic ability of writing wheel eye + white eye - insight and perspective.

Uchiha Itachi nodded approvingly, "Yoshiyo is really smart. Then I'll teach my assistant swordsmanship first, and you can sit here for a while and see if you can complete the first and second steps at once. ”

Sasuke wiped his mouth when he heard that training was about to begin, and looked like I was going to behave well today.

Yiyong tilted his head: "Do you have to go far in training?" ”

[I have to stay within two meters of them.] 】

As everyone knows, how cute his puzzled movements look.

[It's rare to see Yiyong so cute.] 】

[Do you want to buy a camera later!] 】

Itachi narrowed his eyes and covered the little twinkling star in it, "We're training not far away, or we'll disturb you." The first time you extract the chakra, it is better to sit quietly. ”

"I'll follow you."

Yi Yong didn't explain, and after covering the food with a lid, he said flatly, "Let's go." ”

Itachi and Sasuke looked at each other.

Itachi: [Today's volunteers are a little strange. 】

Sasuke: [Is there something wrong?] 】

Although they had doubts in their hearts, they didn't want to go against the will of the righteous bravery, so they took him to a clearing surrounded by several large trees in the middle of the forest.

Behind the trunks, tops, and leaves of these large trees are red and white targets, with dense dents of large and small sizes. This is where Itachi and Sasuke specialize in shuriken and kunai throwing.

Yiyong didn't speak, quietly watched his two brothers find a good position, and then—

Sit cross-legged in the middle of the two.

Weasel & amp; Sasuke: "? ”

"Yiyong, do you have to sit here?"

Sasuke scratched his head with the kunai's handle, "I'll be hurt by mistake." ”

As always, he couldn't quite understand the other party's purpose in doing so.

"You can't hurt me."

Yiyong said with great certainty, "Itachi won't hurt me. ”

Sasuke's face bulged and visibly turned a red of shame to the naked eye. [Do you want to learn how to light candles?] Flooded into his mind again.

Fortunately, Yi Yong picked up the next sentence.

"I want to be closer to you."

After speaking, he looked left and right with a puzzled gaze, looking at the expressions of the two, "Can't you?" ”

Sasuke felt the red clouds hanging over his head suddenly be pierced by sunlight.

Want to be closer to us?

Compared to Yoshiyu's usual iceberg-like attitude, Sasuke felt like crying a little.

That's the surprise of contrast.

At this time, although he was puzzled, Itachi who could do anything, spoke, "In that case, Yiyong is here." With me, Sasuke can't hit you. ”

"Okay."

Yi Yong nodded gratefully, "Don't leave me more than two meters." ”

As he spoke, he stared at Itachi and emphasized, "Especially Itachi." ”

The Uchiha Itachi has a chakra that contains a yin attribute and can brush the resolution of the Moon's Breath, which Sasuke does not have for the time being. Moreover, Itachi provides twice as much resolution as Sasuke every time.

"Okay, no problem."

Itachi feels that he is being relied on by his brother, and a warm smile appears on his face, and he speculates that it was the birthday present he gave to Yiyong yesterday that brought them closer.

Although he has not yet sorted out the details, the sense of accomplishment has gradually taken root in his heart.

Itachi's expression at the moment was in stark contrast to Sasuke's stiff face.

What do you mean? When did your relationship become so good. 】

Sasuke's gaze swept back and forth between the two, his mouth slowly opening wide, and his skin looked a little pale.

[Could it be that Yiyong suddenly opened his mind and wanted to snatch my brother from me? ] 】

[Nope! No! No! Why are Itachi so happy? Is it that he wants to compete with me for righteousness? 】

[Yiyong and I are twins sleeping under the covers! 】

[No! My brother is mine! My brother is mine too! No one can rob me. Obviously, I came first......]

For a moment, he suddenly didn't know who he should be jealous of.

"Sasuke, let's get started."

Itachi didn't notice anything wrong with Sasuke, and asked with a smile, "Yesterday I taught you the technique of throwing three shuriken at the same time, remember?" ”

"Don't underestimate me!"

Sasuke shouted loudly and angrily, holding three shurikens from his waist bag with his left hand and shooting forward, but because the force was too strong, only one hit the target, and the other two flew out from the top of the target and fell into the forest.

"It's a step back, Sasuke."

"It's not all your fault!"

"Why are you suddenly upset?"

"I'm not upset!"

"How do you learn to speak bravely?"

In this way, in the conversation between Sasuke and Itachi mixed with training, Yoshito entered a state of steady, ignoring the noise. Even under extremely dangerous conditions, being able to concentrate and maintain the breathing method is the basic condition for becoming an excellent swordsman, and Yi Yong has long been accustomed to it.

At this moment, he was using the micro-manipulation ability of his body brought by [Penetration] to control the body energy from the cells of his body, as well as the spiritual energy from the "cultivation experience" to gather into his abdomen, and form a slowly rotating cyclone, the scale of which was far from being comparable to Sasuke's ......

Ever since he began mastering the Breath of Water: Tsunachu, Yoshiyu's body has been strengthened by the forces of nature half a year ago, and he has drawn a lot of energy from his body.

If Kakashi's master, Uzumaki Kushina, were alive, he would have found that what Yoshiyo possessed was an acquired [Immortal Body] that was still growing, although it was not as exaggerated as the Uzumaki clan, but the essence was very similar.

As for the spiritual power that is evenly mixed with physical strength, it comes from the experience of fighting ghosts in the seven years of Yi Yong's previous life, and there are also many of them.

Therefore, the energy extracted by Yiyong is much more exaggerated than Sasuke's.

[Next, as long as the cyclone is accelerated, a chakra will be formed-]

However, the change was abrupt.

The third force, with the breath of righteous water, rammed like a fierce beast and broke into the belly of righteous bravery!

[This is ......]

Yi Yong opened his eyes, [The power that the breathing method obtains from the outside world? 】

In the center of Konoha , in the strange insect snack bar opened by the oil girl clan, two toads who were roasting cricket skewers stopped their movements and exchanged glances with each other.

"You're back?"

The toad on the left wondered, "Didn't you say that he was taking materials from Tang Ninja Village?" ”

"This is the movement of someone cultivating immortal arts, who else in Konoha Village can practice immortal arts?"

The toad on the right didn't make such a fuss, "But he dares to play like this outside of Miaomu Mountain, he is so bold, maybe he will become a toad made of stone——"

The toads of Myoki Mountain who practiced immortal arts knew that the natural energy was different from the chakra extracted from the ninja's own body, and it was a very violent power.

This kind of energy is not harmful to toads who do not have chakra, but ninjas with chakra cannot maintain the ratio of 1:1:1 between physical energy, mental energy and natural energy when practicing immortal arts, and will be eroded by natural energy.

In the case of Jiraiya, for example, he can't maintain this proportion stably, so every time he uses Xianjutsu, his face will have the characteristics of a toad, and this is only the consequence of a slight imbalance.

If he absorbed far more natural energy than the other two, he would become a stone toad and would never be able to change to his original form.

And it is this danger that Yi Yong experienced at this time. Once he makes a serious mistake, he becomes a part of nature.

Previously, he had never practiced chakra, so the natural energy from the water breath was only subtly adjusting his physique.

But when he began refining the chakra, two energies from different sources clashed.

"Shhhh

Yiyong remained motionless, frowning and glancing at his little thumb.

When the force from the outside world rushed into his abdomen, it broke the balance with the other two forces, making it impossible for the cyclone to form, and the muscles and skin of his little thumb immediately turned translucent ice blue, like jellyfish. Yi Yong can see through his skin and see his finger bones.

And the stinging pain that came from time to time at that time made him know that he was probably screwed up.

He wanted to ask Uchiha Itachi what was going on, but he couldn't distract himself right now.

Because in that case, the three energies in the body will only become more chaotic.

[Balance, Balance, Balance......]

Yi Yong closed his eyes and used [Penetration] to carefully manipulate his snort, deliberately reducing the efficiency of water breathing and the speed at which foreign energy enters his body!

As everyone knows, the troubles that have plagued the immortal cultivator for many years have been solved by his innate ability.

After about five breaths (i.e., five minutes), another bigger cyclone finally appeared in Yiyong's abdomen.

As the speed gradually increased, a new energy was formed, and a feeling of swelling suddenly came from Yiyong's stomach.

[Is this the ninja's chakra? 】

Not really.

Yi Yong didn't know that he just made a mistake and created the so-called [Immortal Chakra].

The next thing is relatively simple for the righteous courage who can see the chakra meridians.

He directed the immortal chakra formed in his abdomen to his internal organs along the meridians, and stored them in the heart position, and after an unknown amount of time, he finally had a sense of overflow.

At this point, the third step that Uchiha Itachi said has been completed.

Finally, the chakra stored in the body is shunted into the chakra acupuncture points that control the chakra eye -

Outside, Uchiha Itachi, who was teaching Sasuke Kunai to throw in an arc, subconsciously turned around and looked at a pair of one-hooked jade writing wheels.

“？”

He blinked violently, his first reaction was that he had misunderstood.

[How can it be so fast?] 】

[It's not been a day?] 】

Later, it was Sasuke's exclamation that pulled him out of his mental shock.

"Yiyong, is this your writing wheel?"

Sasuke wiped his hands on his clothes, squatted down curiously, and held Yoshiyu's face to look at him, "Is there anything unusual?" ”

"Hmmm......"

When Yoshiyong's "chakra" was full, he stopped the process of the cyclone in his body and seriously pondered Sasuke's question.

"I see more colors."

For example, Sasuke's face, which used to look like a healthy white pink, can now even divide Sasuke's face into five different color blocks.

Then, he opened the [Transparent World] and superimposed it with the dynamic visual effect of the writing wheel-

[Sasuke's blood flow rate seems to have slowed down a bit......]

"You're moving more slowly."

"Brother?"

Sasuke turned his head with envy and looked at Itachi, who was definitely not happy, "Is this the power of the Sharingan?" ”

"Well, the Sharingan has the power of insight similar to a microscope and a magnifying glass, and the movements it sees are as slow as a slowed movie, in addition to the ability to cast and bounce illusions from Muji......"

Itachi slowly introduced, "However, the specific effect still depends on the strength of the user's pupils. If it's a three-hooked jade writing wheel, the shuriken you just threw out will be as slow as a falling leaf in the other party's eyes. ”

"Good, good!"

Sasuke was even more envious, "Then when will I be able to have my own writing wheel like Yoshiyong?" ”

“……”

[When misfortune happens. 】

Itachi wanted to say, "When you grow up, you'll naturally have it", but Yoshiyu's counterexample is close at hand, and he obviously can't cope with Sasuke's enthusiasm.

So he was silent for a while, squatted down, reached the level of Sasuke, and said very gently, "When you need to become stronger, the Sharingan will awaken." But now there is me...... and Yiyong take care of you, so you don't need to open your eyes yet. ”

"......" This time it was Sasuke's turn to be silent, and he vaguely felt that his brother's expectations of him seemed to be very different from his father's.

My brother didn't want him to open his eyes.

I don't know why, but Itachi won't hurt him. Sasuke was convinced of this.

A faint tearing sensation appeared in his chest, and he wanted to be recognized by his father without going against his brother's wishes.

So he turned to Yiyong, hoping to get an answer from the third person.

But at this glance, he seems to have found some clues......

"Why, I feel that the color of Yiyong's writing wheel eyes is different from when my father showed me in the morning?"

He asked, his whole face almost against Yiyong's nose, "as if it was shallower......

"Really?"

Yiyong was stunned, and cast a questioning look at Itachi, "Is it caused by pupil power?" ”

"No, the pupil power will only affect the strength of the effect of the writing wheel eye, which is manifested in the number of hooks in the eyes."

Itachi also came closer, and he first turned Yiyong against the light, and then met the light, which confirmed that Yiyong's eyes were different from his father's, and it was not just an illusion.

The eyes of the righteous and brave writing wheels are not scarlet like blood, full of fierce and violent feelings, but the colors of the orange-purple clouds reflected on the water surface in the evening, cold and warm, as if a layer of light blue mist is covered with a layer of light blue mist on the normal writing wheel eyes.

Itachi only then realized that Yiyong's natural pupil color was different from the pure black of his clan, but a lonely dark blue.

Perhaps it is precisely because of this that his writing wheel eyes look so ...... Mild?

"When you're normal, your eyes look scary."

Sasuke said what Itachi wanted to say, "Daddy is different. ”

"Can you skillfully close the writing wheel?"

Itachi asked.

"Yes."

Yi Yong manipulated the chakra reflux in his eyes and returned to his original appearance.

[Although it's not good to say that.] 】

After staring at Yoshiyo for a while, Uchiha Itachi thought to himself.

[I'm afraid that Yoshiyo is the only child of the Uchiha clan who looks more reassuring when he opens his eyes than when he doesn't.] 】

"As long as you can switch it on and off freely, it's not too much of a problem."

Itachi paused, "If you want to improve your pupil power, just use the ability of the Writing Wheel Eye more." Generally speaking, adult clansmen will exercise to the trigram within four or five years after opening their eyes, and if they encounter some emotional stimulation, it will be faster, but this method is not very stable. ”

[The premise of the three hooks is that their chakra amount must also be close to the level of the upper ninja, otherwise there will be an unknowable change in their personality. 】

"As for the illusions that rely on the Sharingan......"

Itachi opened his writing wheel eye, and the three magatama slowly turned around, and the Itachi in Yiyong's eyes immediately turned into a huge crow, and in the blink of an eye, it became Itachi's original appearance.

Imaging, directly in other people's minds, is the basic application of the Writing Wheel Eye Illusion, of course, it is also the easiest to crack, Itachi just demonstrated it to Yiyong.

"If you need it, you can learn, the specific content is on a few stone tablets in the shrine of the clan, as long as you open the writing wheel eye, you can see it."

At the moment when Itachi's illusion ended, a prompt sound sounded in Yiyong's head.

[Uchiha Itachi used the Writing Wheel Eye Pupil Technique by your side, Moon Breath Resolution +0.003%, current progress 10.003.] 】

Yi Yong was happy at first, and then found out that the resolution increase value of Moon Breath was not the same as the Flame Breath of 3/10,000, but 3/100,000!

In other words, it is ten times more difficult to fully parse the Breath of the Moon than the Breath of Fire!

[The 10% I already have, it should be that I have a hook jade writing wheel eye, just like the basic 20% of the resolution of the breath of fire, because I am an Uchiha and am born with fire attributes. 】

[If the pupil power of the writing wheel eye is improved, to the second hook jade and the third hook jade, will it directly increase the progress by another 10% or 20%?] 】

[But in this case, the writing wheel eye must be commonly used.] What Itachi said about the Uchiha illusion ......]

"Not necessarily."

Yoshito shook his head, "I don't want to learn the Uchiha clan's jutsu. ”

He felt that since he didn't plan to serve the Uchiha clan and become a ninja, he had no reason and qualification to learn ninjutsu, just like a person who didn't kill demons had no reason and qualification to learn the sword type of breathing method.

[As for improving pupil strength, it's good to cook with the writing wheel eye open.] 】

Just as Yiyong was about to ask the current time, Yiyong heard a new chime.

[Get in close proximity with Uchiha Itachi for 4 hours, Flame Breath Resolution +0.04%, Wind Breath Resolution +0.02%, Moon Breath Resolution +0.03%]

[Spend 4 hours in close proximity with Sasuke Uchiha, increase the breath resolution of Flame by 0.03%, and increase the breath resolution of Thunder by 0.01%. 】

[It's been four hours.] 】

Yiyong was slightly shocked, looked at Itachi and asked directly, "Do you have a chakra with wind attributes?" ”

"Huh?"

Itachi Uchiha looked at Yoshiyu strangely, "How do you know?" ”

Yiyong lowered his head and did not answer.

He now knows that Sasuke and Itachi, in addition to the fire attribute chakra, should also have the thunder attribute and the wind attribute respectively.

Seeing that Yiyong didn't want to answer, Itachi only thought that when he had seen him use the Wind Escape Ninjutsu, he didn't dwell too much.

"It's already noon, and the morning training can basically be over, Sasuke."

Itachi swiped his head in one hand and smiled with satisfaction, "Besides, since Yiyong has successfully refined the chakra, it's time to test your chakra attributes." ”

Sasuke looked expectant again, "What are we supposed to do?" ”

"There are special test papers, but most ninjas only use this thing when they reach the middle ninja, but you are much ahead of schedule."

Itachi took out two palm-sized pieces of paper from his pocket and handed them to Yoshiyu and Sasuke one by one, "Concentrate your chakra on the acupuncture points on your hands, and this piece of paper will automatically react." If it is a fire attribute, the paper will burn; The Thunder attribute will wrinkle; The water properties will be moist; The wind attribute will tear apart; Soil properties are shattered. ”

"What if there is more than one?"

Sasuke was worried that he only had one chakra attribute.

"Just try it."

Itachi smiled and said, "Don't worry, there's nothing wrong with one. ”

[Dad didn't say it was you when the time came. 】

Sasuke wrinkled his nose in displeasure, and then slowly directed the chakra through the meridians to his hands.

From this point, it can be seen that the biggest difference between Sasuke and Yoshiyo is that Yoshiyo can clearly see the location of each meridian, so it saves a lot of time.

It wasn't until fifteen seconds later that the paper in Sa's assistant changed!

The right half of the paper was lit with flames, but the left half was suddenly constricted like a peeled candy wrapper, and the boundaries were clear, each accounting for half of it.

"Now you can rest assured."

Itachi looked as happy as Sasuke, "It's fire and thunder, fire and thunder, both are very powerful ninjutsu." ”

"Really? That's great. ”

Sasuke grabbed out the faint flame and saved the used test strips as a keepsake.

"Now it's time to be brave—"

Before Uchiha Itachi's words fell, the brave chakra instantly reached his hand, as if he had already practiced it ten thousand times.

The test strip in his hand, as expected, began to burn from one side.

But the next moment.

The test paper bent and melted like falling wax, as if it had been blistered in water for three days and three nights, and the area gradually expanded from a small corner to the whole paper, and even the part that had just been burned was gradually extinguished by the moisture that represented the water.

Itachi's eyes widened.

[This, this is the ......]

This means that this righteous chakra, in addition to the fire attribute that has been passed down from generation to generation by the Uchiha, also has the opposite, the most extreme water attribute!

This kind of affinity, I'm afraid only the second-generation Hokage, and the ninja demigod Sanshoyu Hanzo can be compared!

Their Uchiha clan actually produced a genius who escaped from the water?
