The difficulty of the eyes is really a little beyond the belief of Kei Uchiha and Aya Hinata.

It took four hours, a full four hours, for the two of them to get the damn operation done.

And they all have a feeling of exhaustion after this surgery.

Uchiha Kai is okay, after all, he is just doing some auxiliary things, and he can try to help Aya Hinata when he is most tired.

And Hinata Aya is really too consumed, not to say anything about the whole process, but to stay focused at all times.

Kei Uchiha could clearly see that her back was already soaked.

But the woman gritted her teeth and completed the operation motionless.

This operation can be said to be relatively successful, although the entire operating table looks bloody.

But how to say it, through the white eyes of Hinata Aya, it can be known that the connection of the optic nerve transplanted this time is fine.

And although the two eyeballs are stuffed together, they are not damaged.

As long as these two points are not problematic, then it can be regarded as a success for Uchiha Kei.

In fact, Uchiha Kei has always been curious, what is the situation of this guy Sasuke Uchiha?

Obito's late-stage ability is good, but isn't it possible for this guy to learn medical ninjutsu?

It seems that this 'Uchiha Kenji' may not be as bad as imagined, at least in terms of medical ninjutsu, Uchiha Kei is really a little unenlightened.

After about an hour's rest, Hinata Aya opened her eyes again and observed.

"It doesn't seem to be a problem, maybe because the brothers are blood relatives, the two kaleidoscope writing wheels are contained in one eye socket, and there is no rejection at all."

"Is that so?" Uchiha Kei stood up, then took a seal with one hand.

Soon Uchiha Shu opened his eyes, but blood flowed from the corners of his eyes.

And the two eyeballs in his eye sockets are also bloodshot, and the two different patterns are also particularly weird.

The most important thing is that Uchiha Kei also seems to feel a strange power brewing.

This scene looks unusually weird, even if Uchiha Kai is used to seeing blood, he will feel disgusted, and Hinata Aya is even more dazed.

"What are you doing?" Hinata Aya looked at Uchiha Kei with some inexplicability.

"Check your eyes." Uchiha Kei was also a little strange: "What's wrong?" ”

"The eye transplant has just been done, and if you want our four-hour work to be scrapped like this, then you can continue."

Hinata Aya didn't look at Kei Uchiha with a cold face, she always felt that she had wasted four hours of her time.

“.....”

Uchiha Kei silently withdrew his hand, and Uchiha Shu's eyes also closed: "Why are you still stunned, stop the bleeding!" ”

Hinata Aya didn't bother to pay attention to Uchiha Kei, stood up and walked in front of Osamu Uchiha, and then a green chakra appeared on her hand again.

When Osamu Uchiha's eyes stopped spilling blood, Hinata Aya took a piece of gauze and put it over his eyes, presumably to prevent light leakage and better allow them to merge.

"Don't do anything like this again." Aya Hinata only raised her head after she had done all this.

"If you want both eyes to be scrapped, then you can just crush them, why bother?"

"Count me in." Uchiha Kei shrugged: "I'll pay attention to it later, by the way, I felt a strange force just now, you should have noticed it too, right?" ”

Hinata Aya nodded: "Yes, it should be the resonance of these two pairs of eyes." But I haven't noticed any of them starting to merge yet, can you be sure you're doing the right thing? ”

How do I know, am I going to say I'm just trying it too?

Kei Uchiha did not answer this question, and nothing like it was never described in the original books.

He can only make choices and judgments based on his own ideas and some of the 'books' he has read.

In his mind, there are actually two practices that are the most worth considering.

One is to stuff two kaleidoscopes into the same eye socket and let them blend with each other.

And the other is to find a way to make a technique, a technique that can completely extract the power of the kaleidoscope.

Extract the power of the kaleidoscope completely and let it be abolished, and then infuse these powers into another pair of kaleidoscopes.

This method is relatively extreme, but it is relatively convenient and safe, and it is a pity that Uchiha Kai does not have such hard conditions at all.

The 'Transcribing Seal' may be able to be used for development and research, but the problem is that after Kei Uchiha got this post, he found that he didn't seem to have a development direction at all.

Because this technique can indeed extract the pupil technique, but this technique also has an upper limit, that is, the pupil power it can hold seems to be so much.

Uchiha Kai thought of a lot of solutions, but he didn't solve this problem.

In the end, he had no choice but to abandon the idea and use the most unpretentious, time-consuming, controversial and uncertain method, which is the first method.

"I can only say that this is the only way I can think of it. Maybe there will be better, but I don't have the energy and time to do these things. ”

Uchiha Kai sighed helplessly: "Can you estimate how long it will take this fusion?" ”

"There's no way to predict, I'm not from your Uchiha clan, and I don't believe you don't have an estimated time." Hinata Aya shook her head, she wouldn't make such a review.

"Yes." Uchiha Kai nodded: "By the way, let me tell you, Hinata Hinata's start time should be in October, he has seen me recently, let him cool down first." ”

"Yes, you decide." Hinata Aya had no objections.

Uchiha Kei only needs to do what he promised her, although the materials in her hand are enough to prove that what Uchiha Kei told her at the beginning is correct.

But one more material, one more certainty, she naturally will not refuse such a thing.

As for the follow-up road, Hinata Aya hasn't figured out a solution yet.

But one thing she does know is that she will never try to use genetic modulations or anything like that.

This way of repairing and activating genes is not only painful, but the mortality rate is even more frightening.

Through this period of study, she naturally knows these things.

Paying attention and being careful about all possible situations and taking precautions in advance is a habit that this woman has developed for many years.

When she was learning about cell medical ninjutsu and genetic medical ninjutsu, she kept an eye on it.

For example, be careful where this guy Uchiha Kai will pit himself or something.

"By the way, how are you learning cellular medical ninjutsu?" Just as Hinata Aya was thinking, Uchiha Kei suddenly asked, "Can you do basic experiments?" ”

"Basic experiments?" Hinata Aya came back to her senses and looked at him a little strangely: "Okay, what experiments do you need me to do." ”

"Cell Fusion Experiments." Uchiha Kai said calmly.

"I need to test what is the success rate of fusion between an unfamiliar cell and my cell, what is the probability of lesions, and what is the probability of death.... How, exactly? ”

Uchiha Kei said very calmly, but he couldn't help but feel a little hot in his heart.

It's been so long, it's been so long since he got the white absolute cell, and he's been patient not fusing it.

Although there was Uchiha Obito as a precedent, and he remembered that the cells of the White Jedi could almost be called the cell body between the Thousand Hands Pillar without any side effects.

But when he thought of the whitish half of Uchiha Obito's body, and the head on Madara Uchiha's chest, he forcibly held back.

It also takes time to train a working medical ninja, but luckily he still has time for him to consume, so he can wait patiently until now.

And now, he's going to start testing those cells, and he's going to do better!

He didn't want to be a dirty person, or as white as Orochimaru.

I don't want anyone's face to appear on my chest inexplicably.

"If it's a woman, forget it, but the face of a man appears.... I'm not Madara Uchiha! ”

"Someone else's cells, fused with yours?" Just when Uchiha Kai's heart was shattered, Hinata's voice brought him back to his senses: "What the hell are you going to do?" ”

"One study, one experiment. Can you do it? Uchiha Kei looked at Hinata Aya calmly.

"This experiment is important, for me.

Actually, I'm not going to take it out so quickly, I'm going to finish studying what the eyes are saying.

But now I've changed my mind, because it seems to be laying the groundwork for me as well. ”

That's right, Uchiha Kei did change his mind.

His original idea was to follow Madara Uchiha's path and follow his successful experience step by step.

But just now, after seeing Osamu Uchiha's terrifying and hideous eyes, he seemed to realize a problem.

It's not the one that fuses the power of the Thousand Hands Pillar first, and it can't be done on the road to improve the writing wheel.

It's that it is impossible for Obito to have an eternal kaleidoscope writing wheel!

According to the previous practice of Uchiha Kai activating the gene for Uchiha Madara, or repairing the gene, not getting the Eternal Eye is actually part of the gene loss.

Obito was so bad after fusing with the Ten Tails that he was almost devoured by the Ten Tails.

Madara Uchiha doesn't have such a situation, I'm afraid the gap in the middle is the problem caused by the deletion, or the gene that has not been repaired and activated, right?

"You can try, but I can't guarantee success." Hinata Aya thought for a moment and nodded.

"Are you sure you need enough materials, though? If the material is not enough for me to carry out batch testing, I'm afraid I can't guarantee it. ”

"There are enough materials, you can rest assured, I have already prepared for it." Uchiha Kai smiled.

How much more than enough material?

He has two white bodies, not to mention that Uchiha Kai also thought of a question.

Since his kaleidoscope has a technique that is accelerated, can he make these eternal eyes catalyze faster?
