Uchiha: Blind in both eyes, the world is suppressed by the eyes of the mind

"This is a required course for ANBU, but obviously, I haven't mastered it yet."

Kakashi was discovered before he even entered the training ground area, and Kakashi's original confidence in his concealment methods was shaken.

"Your talent is well known to everyone; just like my power of hearing, there are few opponents! So, there is no need to be discouraged."

Uchiha Shin's words fully embody the win-win situation in business solo.

Kakashi curled his lips, obviously immune to such compliments.

Compared to the time he spent in the Anbu training and performing tasks day and night, like a machine without emotions, seeing Uchiha Shin at this time and listening to the other person's shameless boasts relieved his heavy heart.

"I heard from Minato-sensei that you haven't given up on practicing the Thunder Release Ninjutsu yet?"

Since Uchiha Shin has never revealed the results of the change in the nature of his thunder attribute chakra, and he himself has no thunder attribute talent, Kakashi's understanding of his thunder escape training is still at the difficult entry stage.

"That's necessary. Just imagine, the spiral blasting pill in the left hand and the thunder escape thousand birds in the right hand. The enemies will be frightened when they see it!"

Xin looked like a pig and fantasized, but Kakashi sneered.

"You should know that Chidori is still in its infancy, and the chakra is not yet condensed enough. However, it has reached A-level learning difficulty. You know what it means."

"The prototype is better, which will facilitate my subsequent development of derivative ninjutsu!"

Even if Chidori is immature, it will not affect his cultivation.

In fact, it doesn't matter whether Uchiha Shin learns Chidori or not. Other thunder escape ninjutsu are also fine. Anyway, the purpose is to increase the strength of Sharingan's eye by practicing thunder escape.

"Really? You should know that Chidori has the biggest flaw, but it is the part you are most lacking."

Kakashi reminded again without comment.

"You mean the Sharingan? That's a problem, or maybe it's not."

Xin said with a smile.

"What do you mean?"

"Before there was the Sharingan, the Chidori would affect your vision and activate the body cells. The speed would be much faster than usual, making it harder to hit the target, right?"

"Ah."

Kakashi responded in a low voice and waited patiently for the next sentence.

"With the insight of the Sharingan, the enemy can't hide under the rapid speed of lightning."

Xin continued, but Kakashi did not respond, but touched his left eye that was blocked by his forehead protector.

"What if I don't see with my eyes?"

“The sound of a thousand birds, like the chirping of hundreds of birds, also has a great impact on your hearing.”

Kakashi retorted.

"Not only do I have better-than-average hearing, otherwise I would have died on the battlefield."

Xin was conscious of his power of perception. From the past battle information, many people had already made speculations, so he simply made it public.

"Sensei once told us that you have sensory abilities beyond those of ordinary ninjas."

When Kakashi said 'us', his eyes darkened and he adjusted in an instant.

"Is it alright now?"

"Well, I have a condition."

"tell me the story."

"No matter the Chidori, or the ninjutsu developed by the Chidori, no matter what the situation is, you can't use it on your Konoha companions!"

I don’t know if Kakashi is because his Chidori penetrated Nohara Rin’s heart, or if he sees the tense relationship between Uchiha and Konoha.

"no problem."

Xin agreed straightforwardly.

[Uchiha Shin will not use the Chidori Ninjutsu to deal with Konoha's enemies, but someone else will do it! 】

He will not be so pedantic that he will insist on this promise if he or his companions are threatened.

"There are two types of Chidori's seals. With your lightning escape talent, it will be relatively easier to practice with the longer seal first."

Kakashi began to form seals slowly while chanting in his mouth.

"Shen-chen-zi-you-chou-si-shu-wei-shen!"

嗗...嗞~婗~~~

In the palm of his right hand, an irregular and thunderous energy body condensed.

"Is this Chidori? It feels very powerful, but it's just not suitable for assassination operations!"

The voice was too obvious, slightly conflicting with Xin's low-key character.

[Besides, for ordinary people, forming more seals is helpful for practicing Ninjutsu. For me, a half-handed person, having too many seals is not a good thing. 】

Fortunately, Xin is a 13-year-old with a ninjutsu attribute. As expected, he can release it with one seal.

"What is the other seal sequence?"

[It ends with 'Shen'. What about the other one? Could it also be 'Shen'? 】

Xin must determine what the tail seals of most Thunder Release Ninjutsu are, then he can use this seal to release all the Thunder Release Ninjutsu he has learned.

嗗~~~啵~~

Chidori was dismissed by Kakashi. He felt that Xin was a little too ambitious, but he did not refuse.

"Another kind, Zi-Wu-Shen-Wu-Mao!"

Hey... Hey~

This time, the thunder was stronger and the birdsong was weaker.

[Could this be the future Raikiri? 】

"Okay, I've written down the sealing technique."

Xin didn't bother to memorize all the seal styles. After comparing the two sets of seal sequences, 'Shen' appeared once at the end and three times in total, which was the most common seal style.

[Then, the common tail mark of Lei Dun is most likely 'Shen'. 】

"The next step is to guide and condense chakra. You can learn the Rasengan. This step will not be too difficult for you. It's just that... you need to transform more thunder attribute chakra in your body. carat."

Kakashi told the Chidori training methods one by one. During the process, after using the Chidori twice again, his forehead was sweating and his right hand was trembling slightly.

The 'Kirin Arm' that has been trained for more than ten years, under the influence of Sharingan, a big 'chakra' eater, Kakashi's endurance is not as good as before.

"Kakashi, your chakra..."

Xin pretended not to know the reason and said pointedly.

"Well, since the Sharingan was implanted, part of the chakra in the body has been continuously absorbed by it, maintaining the open state of the Sharingan."

After all, Kakashi is not of Uchiha bloodline and cannot freely close the Sharingan.

For him, it was really a dilemma.

Without the Sharingan, the power of the most powerful ninjutsu he developed would be greatly reduced, and he might be killed one day because he couldn't see clearly.

With the Sharingan, chakra has been absorbed and consumed, which inhibits the improvement of one's own basic strength. Even if you can rely on the Sharingan to copy a large number of ninjutsu, you can only choose a few most suitable ones to major in.

"Maybe you can try the sealing technique, and you can ask Kushina-sensei for advice."

In Xin's impression, there seems to be no problem in the world of Naruto that cannot be solved by sealing techniques.

If so, it means that the sealing technique has not yet been mastered.

"Well, the teacher also said it a while ago, but the teacher has been busy handing over various matters recently, and my wife knows very little about the Sharingan, so I have delayed it for the time being."

"That's true. No one has successfully implanted the Sharingan before, so no one has studied how to seal the consumption of one's own chakra by the Sharingan."

Uchiha Shin said thoughtfully.

[Perhaps, in the original work, if the Minato couple had not died, it would have been possible to develop a way to limit or even solve Kakashi's Sharingan problem. 】
