Naturally, the sooner the better.

If it weren't for the uncertainty of when it would be time for the Hyuga clan to release them, I'm afraid Uchiha Kai would have to do it himself a long time ago.

Although the fusion period of the Eternal Kaleidoscope was a little long, he didn't want to miss any of it.

Soon, Uchiha Kei handed over the task to Kenta Imai and Uchiha Kawa, and he took Hinata Aya to the underground laboratory.

Now that there are fewer people stationed in the underground lab, it is natural that some people must be drawn out of them to support Kakashi.

However, although there are fewer people, the precautions in this vicinity have long been fully arranged.

Uchiha Kei and Uchiha Fugaku don't have to worry too much, there will be some people who shouldn't be here and run into their most secret place for no reason.

After entering the laboratory, the two of them went directly to the room where the brothers Osamu Uchiha and Isamu Uchiha were kept.

The two men were still soaked in the vid's nutrient solution, and it looked as if they were asleep.

After the life-support cabin, Uchiha Kei and Hinata Aya lifted the two out and put them on the bed on the side, and then added various equipment to Uchiha Shu's body.

After all the equipment to monitor vital signs was arranged, Hinata Ayacai opened her mouth and asked, "Do you want to remove the eyes of Isamu Uchiha directly?" ”

"Well, just remove it." Uchiha Kai nodded: "Be careful not to hurt your eyes, and kill him after removing it." ”

Uchiha Isamu's body has been studied almost, and he has been able to maintain his vital signs until now, and the biggest use is to use it as a container for the kaleidoscope writing wheel.

This guy has been completely erased from consciousness, and it can be said that he is dead in the real sense.

And Uchiha Kei can also be regarded as the fulfillment of his promise.

Uchiha Kei didn't go to trouble his beloved woman and his family, and he didn't do anything to his family other than his brother.

Uchiha Kai felt that he had done his best to be benevolent, and let him still exist in the world so painfully, it was better to let him leave.

He won't be too lonely on the way to the Pure Land, and I'm afraid it won't be long before his brother will accompany him.

Hinata Aya nodded and didn't speak, and Uchiha Kai decided that she just had to do it.

Lowering her head, a green chakra glow quickly appeared on her hand, and then her hand covered the Uchiha Yu's eye sockets.

Removing eyeballs is not too difficult, and Hinata Aya can easily do it without even opening the white of her eyes.

It only took less than five minutes for the two scarlet eyes with strange patterns to be perfectly removed by Hinata Aya.

Although these eyes have lost their owners, they still have a strange aura, as if one more glance will make people fall into it.

Hinata Aya's face became a little solemn, and these eyes gave her a very bad feeling.

She couldn't imagine how terrifying it would be for someone to use such eyes.

Taking a deep breath, Hinata Aya's green chakra-covered hand rubbed against Isamu Uchiha's artery.

Uchiha's body suddenly paused, and soon he couldn't even breathe.

Uchiha Kei didn't even look at Uchiha Yong's condition, and his eyes were also locked on the pair of kaleidoscopes, but now Uchiha Kai seemed to think of something.

The fusion of the Eternal Kaleidoscope Writing Wheel Eye is the pupil power of one party devouring the other.

But whether or not to retain the power of the other pair of eyes is really up for debate.

He realized that he seemed to have missed one thing all along, and that was that Sasuke Uchiha, even if he had Uchiha Itachi's eyes, didn't seem to have used such an illusion as Tsukiyomi at all.

And the power of Amaterasu seems to be due to some kind of 'transcribing seal' or some kind of technique.

It was by transferring the power of the pupil that Sasuke used Amaterasu in the three hooks, so the ability to be retained?

Uchiha Kei was a little unsure, but after thinking about it carefully, he didn't think it was of much experimental value.

These eyes won't be his in the end, and if he doesn't retain the pupil technique of the fused side, it will be a big profit for Uchiha Kei.

Although it is a little pity, Uchiha Yuna enhances Susanoo's ability.

After all, having that ability can let him know, and then Susa Nenghu's feelings, but if it's not his own, it's not necessarily suitable for it.

"And this ability, I'm afraid it reduces the conditions for the use of Susanoo, or in the case of the same power, it enhances the power of Susanoo, and the reference value is average."

Now Uchiha Kai's Susanoh has been developed to the point where he has reached the second state in the kaleidoscope writing wheel eye state.

And in the state of Sangoyu, he can barely maintain the first state, but this is still a little difficult.

However, such a state is completely sufficient at this point in time.

Thinking of this, Uchiha Kei simply decided not to worry about whether the ability of these eyes was true or not, and Uchiha Shu's ability was not bad.

When Uchiha Shu was forcibly opened by Uchiha Kai and Uchiha Fugaku, the level of stimulation he received was really not low.

Probably because he knew the truth and his brother's current situation, he was extremely eager to have enough strength to kill the two people in front of him.

Therefore, the power displayed by his eyes is very proudly interesting.

One is the same as his brother, Amaterasu.

This is known as the strongest attack but has never died in the Hitomi technique, and the other is an ability that Uchiha Kai has never heard of, calling fire to illuminate life.

Fire and earth seem to be two similar but somewhat opposing abilities.

Adds the effect of Earth Life, making Amaterasu's flames malleable.

Sasuke Uchiha is a representative of the use of the earth.

Under his control, Amaterasu's flames were completely controlled and submissive, and could even be turned into ground thorns to use.

And then Sasuke cooperated with Naruto, and what kind of 'Light Wheel Blast Paint Black Arrow Zero Style' was used.

The ability of fire is different, although it also acts on Amaterasu, but its effect is infinitely amplified by the power of Amaterasu's flame!

Whether it is the improvement of quality or the expansion of the scope of use, it can be easily completed with the cooperation of this surgery.

Uchiha Kei knew how terrifying the effect of Amaterasu and this technique was when they were used recklessly.

In the original book, when Uchiha Itachi faced Sasuke, he used Amaterasu to cover most of the forest.

If you use fire, I'm afraid the whole forest and even the wider area will not be a problem, right?

"Let Uchiha Fugaku honestly play with fire."

Thinking of this, Uchiha Kai turned his head to look at Hinata Aya: "Next is a new transplant, this operation may be a little complicated, are you ready?" ”

"All I can say is that I'll do my best." Hinata Aya said calmly: "After all, I don't have a chance to do an eye-swapping experiment, and it is very difficult to make these two pairs of eyes merge with each other, I have only done it a few times, and I have succeeded once." ”

Hinata Aya is not lying, she really has very little experience and practical ability in this area.

Although Uchiha Kai had told her in advance, there were really not many practical opportunities she could get access to.

Uchiha Kai nodded, he knew something about the situation, but there was nothing he could do.

What's more, Hinata Aya's main task is to study genes and cells, and it is a good result to be able to change her eyes.

"Then let's do it." While speaking, Uchiha Kaiya also opened his writing wheel eyes: "I'll help you, anyway, I also learned Uchiha eye replacement surgery, but I don't dare to come casually for such an operation." ”

"Well, I see." Hinata Aya nodded, then walked over to Osamu Uchiha with the pair of kaleidoscopes.

This kind of fusion surgery is indeed very troublesome, and Uchiha Kai has not thought about it, by 'transcribing the seal' to extract Uchiha Yu's pupil power, and then seal it into Uchiha Shu's eyes.

But as his status grew, he read some of the family's notes.

It's not that no one has tried this, but it turned out to be very useless.

Transcribing the seal can indeed transfer some of the pupil power, even including the ability, but it can't reach the level of devouring fusion.

It can even be said that because of that sealing technique, it has become an obstacle to the fusion of pupil power.

But once the seal is removed, it will cause the pupil power to pass, and even the ability of the seal inside will explode.

Even if Uchiha Shu and Uchiha Isamu are a pair of brothers, the consideration for such a thing to happen is very big, and Uchiha Kai is not willing to take this risk at all.

This is another reason why Uchiha Fugaku chose to compromise after seeing that he had a kaleidoscope.

In addition to not necessarily being able to fight, another thing is that he knows that the eyes of Uchiha Kei have nothing to match him.

Even if he gets it, it is impossible for him to make a qualitative change in his kaleidoscope writing wheel.

As for changing eyes?

What's the use of that?

The power of the kaleidoscope is preserved in the eye, and the body is nothing more than a container for the kaleidoscope.

If the eye change really worked, Madara Uchiha and Izuna Uchiha would have been eternal eyes long ago.

The two of them drove together to beat the Thousand Hands Pillar, where was there any mess later?

In other words, the same goes for Uchiha Itachi and Uchiha Sasuke.

When Sasuke opened the kaleidoscope, Uchiha Itachi told the truth, and then the two changed their eyes together, where is there so much?

Well...

However, Uchiha Itachi's heart to die may not change, and the sins he committed are enough to die 10,000 times!

But now what is going on with this kid, he is not so clear.

It's been a long time since Uchiha Kei deliberately told him something from his standpoint and things that his current vision can't reach.

And Uchiha Fugaku is not in the mood to talk about his son, Uchiha Kai naturally won't ask, he really doesn't want to see that kid more.

Out of sight and out of mind, as long as he is there, this kid doesn't want to stir up any waves.

Not brainwashing Uchiha Itachi was his own decision, because for him.......

Instead of addressing the problem from performance, it is better to tackle the root cause!
