"Makoyi-kun, this is really surprising."

Orochimaru carefully observed Seiichi's golden snake eyes that came out of his body.

"Although I've roughly tested the chakra between you and me that doesn't repel too much, your body seems to be adapting better than I thought."

In the research institute without outsiders, Orochimaru is blunt.

"Isn't that unusual?"

Seiichi didn't think it was strange, after all, Rin was almost plug-and-play when he changed Kakashi's eyes, and he had been used to it for a while.

And in the face of his disciple's almost ignorant and fearless speech, Orochimaru smiled in that hoarse voice:

"Do you know why the Uchiha clan is so opposed to eye transplants?"

Seiichi rolled his eyes and said:

"Isn't it because I'm afraid that the writing wheel eye will be coveted by others, and my housekeeping skills will be left behind?"

Orochimaru put down the medical flashlight in his hand and could not be denied.

"It's one of them."

"But unlike the white eyes of the Hyuga clan, the Uchiha clan's writing wheel eye is not stable, and there will be a phenomenon of anti-devouring host, so although the transplantation of the writing wheel eye has been tested by predecessors, it is just the end..."

He sneered under his breath, as if he was amused by the hasty attempts of his predecessors.

"So the fear of others coveting the Sharingan is not the main reason why they reject transplants."

Obviously, Orochimaru's research on the writing wheel eye is not only the conclusion of his own experiments, but also inherits the lessons of his predecessors.

To this day, it is still the proud secret art of the strongest family in Konoha, so you can imagine how many people have been interested in these scarlet eyes.

Konoha actually happens to have such a talented genius who has devoted himself to studying the mystery of the Wheel Eye.

The second generation of Hokage, between a thousand hands.

Presumably, Orochimaru's understanding of the writing wheel eye also greatly inherited the research results of this forbidden genius ninja world's first speed.

The reality is exactly what Orochimaru said at the moment.

Although the world covets the power of the Sharingan, there has never been any overtly foreign Sharingan owner before Kakashi.

Even a talented ninja like Kakashi has become a man in extreme need for chakras because of the eye entrusted to him by his best friend.

You must know that the chakra used by the ninja is not a natural energy of spiritual power and immortal energy that comes from the outside.

It is the product of the combination of human vitality and spiritual power.

The shortage of chakras will directly lead to a decrease in life activity, and even the mind will be affected by the fullness of chakra.

Spiritual power may be unlimited for the time being due to idealism, but there is a rough upper limit of human vitality.

In a sense, refining chakra is also squeezing one's own life force, and it is overdrawing one's own life.

And if the chakra really dries up, then it will face death.

It is also for this reason that a writing wheel eye that can never be closed, placed on a genius like Kakashi, may be said to have advantages and disadvantages in one or the other.

For people with a slightly more ordinary talent, a writing wheel eye that should not appear on their body is actually like a life-urging ghost, eating away at the host's vitality all the time.

Therefore, even a life science pioneer like Orochimaru, who is full of adventurous spirit and has transformed his whole body beyond recognition to resemble a human being, has never had the idea of directly transplanting the Sharingan.

From this point of view, the first transaction is likely to be because of his own mouth, which made Orochimaru have a guess that he shouldn't have.

Orochimaru looked at Seiichi who was thinking, but he didn't continue to sell Guanzi anymore.

"In fact, the main reason why the Uchiha clan opposes the transplantation technique is because the transplantation of this technique is one-way."

Such words were somewhat unexpected.

One-way?

It means that others can transplant the Sharingan Eye even though they will have an extra burden, but the Uchiha can't transplant an ordinary eye?

What else is going on?

Xu is because he hasn't shown his eyes for too long, and although Seiichi doesn't have any additional facial expressions at the moment, the surprise in his eyes still betrays him.

Orochimaru was obviously satisfied with Seiichi's expression at this time, and then explained:

"Of course, the Uchiha clan also has alternative reasons why they would rather be blind than abandon pride... But the most important thing is that it doesn't work at all. ”

"After my research and research, I found that writing wheels is actually just an expression."

Seiichi frowned: "Expression? ”

"It means that it is not the root of the Uchiha family's bloodline limit."

At this moment, Orochimaru is like a true mentor, carefully explaining the doubts in his heart for Seiichi.

"In the research of the second generation of adults, it has been found that when the Uchiha clan experiences huge mental fluctuations, a special chakra will be produced in the brain in large quantities."

"This chakra will be transmitted to the eyeball through the optic nerve, which will change the appearance of the pupil and give birth to a peculiar blood pupil technique, which is the writing wheel eye."

Orochimaru smiled lowly: "In a sense, the appearance of the writing wheel eye is just a 'hole' formed by the release of that special chakra from the eye, and it is not inappropriate to say that it is a sequelae. ”

"After forming these unique 'holes', the so-called 'pupil technique' will be engraved in the eyes, so even if it is transplanted by outsiders, it can be performed, but without that special chakra, I am afraid that the burden will increase dramatically."

"Therefore, the second generation of adults named this special chakra used for the Writing Wheel Eye Pupil Technique 'Pupil Force'."

Seiichi's brows deepened, and he gradually connected the secrets of the Sharingan that Orochimaru had told.

"So I guess what the teacher wants to talk about should be that ordinary people's eyes can't form a 'hole' with this chakra, which is also a sign of writing wheel eyes, which also means that the special chakra has lost the threshold of release?"

"So..."

"Yes, if the Uchiha people who have opened the Sharingan Eye transplant the eyes of ordinary people, there is a high probability that the special chakra that has nowhere to diverge will be directly 'incinerated to'."

The smile on Orochimaru's face gradually became perverted.

"Seiichi-kun, now you can understand what I said about the accident, right?"

Makoto Uchiha gasped.

I didn't expect that the first step of my first start would be so risky?

The mystery of writing wheels, it turns out that there are two sides of the same coin?

After opening, the Sharingan only carries the 'jutsu', and the 'power' used to form this jutsu comes from the 'unique' bloodline and chakra of the Uchiha clan.

Orochimaru's research may stop there, but Seiichi knows that in fact, that special chakra is actually very similar to the so-called Yin Escape Chakra.

It was a special chakra built with spiritual power as the main body, and its essence was the yin and yang sides formed by the six immortals when they separated the two brothers.

Indra bears yin, and asura bears yang.

Yin is the spirit, and Yang is the life.

The ordinary chakra follows the basic principle of 'fifty-fifty division' of spiritual power and vitality, and the attribute chakra is actually just fine-tuning the proportion and controlling the nature and form on top of this.

A trace of cold sweat soaked from Seiichi's forehead.

The secret that Orochimaru told him seemed to have broken through a very terrifying thing.

The Uchiha clan's writing wheel eye is not as strict as the white eye, in the final analysis, it is because others use it with half the effort and will be counterattacked.

But if they knew that if they were proficient in the Yin Chakra and then adjusted to the Writing Wheel Eye, they would be able to urge it relatively normally...

Isn't it a little too much fun?

It was the first time Orochimaru had seen Seiichi like this, so he was in a good mood and laughed under his breath.

"Hmph, do you feel the charm of exploring the mysteries of life? Seiichi. ”

...

"Well, Orochimaru-sensei, you can surprise me every time."

It's just more frightening.
