The difficulty of transplanting these eyes is really beyond the belief of Uchiha Kei and Hinata Aya.

Four hours, four whole hours, it took the two of them to complete this damn operation.

And they all felt exhausted after the surgery.

It's okay for Uchiha Kei. After all, he is only doing some auxiliary things. He can try to help Hinata Aya when she is most tired.

Hinata Aya, on the other hand, really consumed too much. She rolled her eyes and said nothing during the whole process, and she had to stay focused at all times.

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

But this woman gritted her teeth and completed the operation without moving.

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

But anyway, from Hinata Aya's eye roll, we can tell that there is no problem with the connection of the optic nerve transplanted this time.

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

As long as there are no problems with these two points, it can be considered a success for Uchiha Kei.

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

Obito's late-stage abilities are pretty good, but could it be that this guy has also learned medical ninjutsu?

It seems that this 'Uchiha Kenji' is not as bad as imagined. At least in terms of medical ninjutsu, Uchiha Kei is really a bit unskilled.

After resting for about an hour, Hinata Aya opened her Byakugan and observed it again.

"It doesn't seem to be a problem. Maybe it's because the brothers are blood relatives. The two Mangekyō Sharingan are contained in one eye socket, and there is no rejection at all."

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

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

The two eyeballs in his eye sockets were also covered with bloodshot eyes, and the two different patterns looked particularly weird.

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

This scene looked extremely weird. Even if Uchiha Kei was used to seeing blood, he would feel sick. Hinata Aya was even more confused.

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

"Check the condition of your eyes." Uchiha Keiya was a little surprised: "What's wrong?"

"The eyes have just been transplanted. If you want our four-hour results to be discarded, then you can continue."

Hyuga Ling looked away from Uchiha Kei with a cold face. She always felt that she had wasted four hours.

""

Uchiha Kai silently retracted his hand, and Uchiha Xiu closed his eyes: "Why are you still standing there, stop the bleeding!"

Hyuga Aya was too lazy to pay attention to Uchiha Kei, stood up and walked in front of Uchiha Shu, and then green chakra appeared on her hand again.

After Uchiha Shu's eyes stopped bleeding, Hinata Aya took a piece of gauze and covered his eyes. This was probably to prevent light leakage and better integrate them.

"Don't do such things again." Hinata Ling raised her head after finishing all this.

"If you want these two pairs of eyes to be scrapped directly, then you can just crush them. Why do that?"

"That's my problem." Uchiha Kei shrugged: "I will pay attention to it in the future. By the way, I felt a strange force just now. You should have noticed it too, right?"

Hinata Ling nodded: "Yes, it should be the resonance of these two pairs of eyes. However, I have not found that they have begun to merge. Are you sure that your approach is correct?"

How do I know? Do I have to say that I just try it?

Uchiha Kei did not answer this question, as similar things have never been described in the original work.

He can only make choices and judgments through his own thoughts and some 'books' he has read.

In his mind, there are two approaches that are actually the most worthy of consideration.

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

The other one is trying to come up with a technique that can completely extract the power of the kaleidoscope.

Completely extract the power of the kaleidoscope and destroy it, and then instill these powers into another pair of kaleidoscopes.

This method is relatively extreme, but it is relatively easy and safe. Unfortunately, Uchiha Kei does not have such hard conditions at all.

The 'Transscription Seal' may be used for development and research, but the problem is that after Uchiha Kei got this, he found that he seemed to have no direction for development at all.

Because this technique can indeed extract the pupil technique, but this technique also has an upper limit, that is, it seems that there is only so much pupil power it can accommodate.

Uchiha Kei thought of many ways, but could not solve this problem.

In the end, he had no choice but to give up this idea and instead used the simplest, time-consuming, and extremely controversial and uncertain method, which was the first method.

"I can only say that this is the only way I can think of. Maybe there are better ones, but I don't have the energy or time to do these things."

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

"There is no way to estimate. I am not a member of your Uchiha clan, and I don't believe you don't have an estimate of the time." Hinata Aya shook her head, she would not make such an evaluation.

"Yes." Uchiha Kai nodded: "By the way, let me tell you, Hinata Hinashi's time to take action should be in October. He has seen me recently. Let him cool down first."

"Okay, you make the decision." Hinata Aya had no objection.

Uchiha Kei only had to do what he promised her, although the materials in her hand were enough to prove that what Uchiha Kei told her originally was correct.

But with more information, there is more certainty. Naturally, she will not refuse such a thing.

As for the follow-up path, Hinata Aya has not yet thought of a solution to this problem.

But one thing she can be sure of is that she will never try to use genetic modification or anything like that.

This method of repairing and activating genes is not only painful, but the mortality rate is also frighteningly high.

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

Paying attention to and being careful about various possible situations and taking precautions in advance are habits that this woman has developed over the years.

When she was learning cell medical ninjutsu and genetic medical ninjutsu, she kept a careful eye on it.

For example, be careful about where this guy Uchiha Kei will trick you.

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

"Basic experiments?" Hinata Ling came back to her senses and gave him a strange look: "Okay, what experiments do you need me to do?"

"Cell fusion experiment." Uchiha Kei said calmly.

"I need to test the success rate of fusion between a strange cell and my cell, what is the probability of lesions appearing, and what is the probability of death?"

Uchiha Kei spoke calmly, but he couldn't help but feel a little hot inside.

It's been so long, it's been so long since he got the white cells, and he has been enduring without fusion.

Although there was Uchiha Obito as a precedent, and he remembered that White Zetsu's cells could almost be called Senju Hashirama's cell body without any side effects.

But when he thought of the white half of Uchiha Obito's body and the image of Uchiha Madara's chest, he forced himself to hold it back.

It also takes time to train a functional medical ninja. Fortunately, he still had time for him to consume, so he could wait patiently until now.

And now, he is going to start testing those cells, and he has to do better!

He didn't want to be Obito, or Orochimaru, who was so white that he didn't look like a human being.

What’s more, I don’t want someone’s face to appear on my chest for no apparent reason.

"If it's a woman's face, forget it, but if a man's face appears, I'm not Uchiha Madara!"

"Other people's cells are fused with your cells?" Just when Uchiha Keinei was heartbroken, Hinata Aya's voice brought him back to his senses: "What on earth are you planning to do?"

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

"This experiment is very important to me.

Actually, I don't plan to take it out so soon. I plan to finish studying these eyes.

But now I’ve changed my focus, because it seems to be laying the foundation for me.”

Yes, Uchiha Kei did change his mind.

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

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

It's not Obito's method of first integrating the power of Senju Hashirama and then improving the Sharingan.

But it’s impossible for Obito to possess the Eternal Mangekyō Sharingan!

According to Uchiha Kei's previous method of activating genes, or repairing genes, against Uchiha Madara, not getting the Eternal Eye is actually part of the missing gene.

Obito was so miserable after merging with the Ten-Tails that he almost had his will swallowed by the Ten-Tails.

Uchiha Madara does not have such a situation. I am afraid that the gap in the middle is the lack, or the problem caused by the unrepaired and activated genes, right?

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

"However, are you sure the materials you need are enough? If there are not enough materials for me to conduct batch testing, I'm afraid I can't guarantee it."

"There are enough materials, you can rest assured, I have already made preparations." Uchiha Kei smiled.

Are the materials more than sufficient?

He has two White Zetsu bodies, not to mention Uchiha Kei thought of a question.
