Starting from Uchiha Obito

Seven days passed quickly, and Wang Jie returned to the meeting place agreed upon with the Uchiha people. The 16 Uchiha people returned one after another.

"Everyone has opened the kaleidoscope, right? Open it and let me see." Seeing that everyone was present, Wang Jie opened the kaleidoscope first and said.

Sixteen pairs of eyes all turned red, and the three magatama inside began to rotate and turned into various shapes.

"First of all, congratulations on obtaining this pair of legendary eyes, but this is far from the end of the Uchiha bloodline. The ordinary Mangekyō only gives us a way to use chakra that is different from ordinary ninjutsu. If you have tried to use pupil techniques, you will know that the pupil power of your eyes is consumed very quickly when using pupil techniques. Once the pupil power is exhausted, using pupil techniques again will damage your eyes, and in severe cases it will directly lead to blindness."

Not every Uchiha knows this knowledge. This is knowledge that is only circulated among the top Uchiha. After all, it is useless for the lower levels to know it, so Wang Jie needs to give them some popular science first.

"In the past, the only known way to solve this hidden danger was for the brothers to sacrifice one of their own and replace one of their own eyes with the other's. This would allow them to obtain the Eternal Kaleidoscope, which was the only way to avoid the fate of blindness.

When he sees someone he cares about die, his eyes will open, and when he is stimulated, the level of his Sharingan will be upgraded. In the end, in order to avoid the fate of blindness, he has to sacrifice his brother. This is why it is said that Uchiha's Sharingan is an evil cursed eye.

But you should have understood that you don't have to see the death of someone you care about in order to open your eyes, and you don't have to be stimulated to increase the level of your Sharingan. All this is just because your mental power is not strong enough. For example, as long as your mental power is strong, you don't need any stimulation to go from opening your eyes to opening the Mangekyo.

So what is the final way to avoid blindness? Look at my eyes. Have you noticed that the patterns on my eyes are different? The left eye with a more complex pattern is the eternal kaleidoscope. You are all my fellow tribesmen, and you should know that I have no brothers.

My left eye became blind due to using Izanagi, and I have a strong regenerative ability, so I replaced my right eye with my left eye, and then regenerated a brand new right eye. Then you see the effect, the left eye that replaced the right eye turned into this brand new pattern. Now my left eye will not be damaged by using pupil techniques. The pupil power has changed from having the functions of both an accelerant and a lubricant to being able to act as an accelerant alone, which greatly reduces the consumption of pupil techniques. At the same time, I don't have to worry about going blind due to excessive use.

So the rumor that one of the brothers must be sacrificed is a false rumor. I don't know where this rumor came from, and I don't know why no brothers have tried to exchange eyes, but I am very sure that even if my left and right eyes are swapped, an eternal kaleidoscope can be formed. I have asked Mingguang to cooperate with me in an experiment once before. Although that time failed, I am basically sure that if my mental power is sufficient, swapping my left and right eyes will be enough to evolve an eternal kaleidoscope. So now I need to conduct another experiment.

What do you think would happen if you exchanged Kaleidoscopes with each other? A friendly reminder, the evolved Eternal Kaleidoscope will include pupil skills of both eyes, so let's first count everyone's pupil skills. If there is a particularly suitable pupil skill combination, you can give priority to the experiment."

Wang Jie's words sparked quite a discussion among the sixteen Uchiha. It was the first time for many of them to hear about the Mangekyō and Eternal Mangekyō. Moreover, not only could Obito allow them all to open these legendary eyes, he could also directly help them evolve into the final form of the Eternal Mangekyō!

The Uchiha clan is the strongest clan without a doubt!

These were the words that echoed in the hearts of all the Uchiha people, even Shisui, who loved Konoha the most, felt at this moment that it was the best outcome for Uchiha to lead Konoha as Hokage. Having already opened the Mangekyō Sharingan, he deeply understood the power of these eyes. When he thought of all the Uchiha people, more than a thousand of them, being brought by Obito to this unique and strange world to open their eyes, open the Mangekyō Sharingan, and then use the appropriate eye techniques to evolve into the Eternal Mangekyō, he could not find a reason not to let the Uchiha people lead Konoha.

All contradictions and conflicts come from the fact that the gap is not big or one party fails to realize the huge gap. Look, the Fire Kingdom and the Grass Kingdom have never had any conflicts.

Under the enthusiastic expectations of the Uchiha, Obito successfully completed the statistics of the eye techniques, and the first pair selected for the experiment were Uchiha Mingguang and Uchiha Tokuma.

After putting the other Uchiha into the Kamui space, Wang Jie quickly returned to the base, opened an advanced training room again, and brought out Mingguang and Dejian.

Their pupil skills are:

Chidi: Controls all fire ninjutsu. Not only can he release his own, he can also release others'.

Red Flame: The power of the fire escape controlled by the Red Emperor is enhanced, and how much it can be enhanced depends on how much chakra is consumed.

Amaterasu: Ignite the black fire that burns everything within your sight. The fuel for the burning is your eye power. As long as your eye power is exhausted, the black fire will never go out.

All Burns: Everything that Amaterasu ignites can be used as fuel.

Even after Wang Jie's reminder, the fire-based eye technique still appeared, which did not surprise Wang Jie. After all, the Uchiha clan has always liked fire. As a clan that is born with fire-attribute chakra, their preference for fire will not disappear because of a few words from Wang Jie. And to be honest, Wang Jie is actually looking forward to the coordination of these four eye techniques.

"This is a drug to suppress rejection. I think the rumor about replacing brothers' eyes is because different people's replacement organs will have rejection reactions. Because the technology was not developed in the War Fruit Era, we were not able to fully understand this phenomenon. In fact, it is only because the possibility of rejection between brothers is lower, and the Mangekyō appears too rarely, which has led to this misunderstanding, and thus the rumor that only brothers' eyes can be replaced. The technology in this world is more advanced than the current ninja world, and we already have long-term and effective rejection inhibitors here. Each of you can drink a bottle and then replace your eyes."

After teaching Uchiha Dejian the eye-swapping technique, Wang Jie gave each of them a bottle of anti-rejection medicine and watched them exchange eyes. The only drawback was that there was only a full-band force field scanner for one person in a training room, so Wang Jie could only observe the standpoint analysis data of one person at a time.

"Still not working? It seems that the fundamental reason why no one has discovered that swapping the left and right eyes can open the Eternal Mangekyo is that the mental power is too low. The purpose of swapping eyes is to have a pair of eyes gather the pupil power of two pairs of eyes, which inevitably requires the sacrificed person to actively cooperate. Even if the gathering point of mental power changes from the brain to the eyes after the Mangekyo is opened, if the person whose eyes are buttoned is unwilling, I am afraid that he will not be able to completely inherit all the pupil power of a person. That's why only one brother can be sacrificed. Rejection is only one aspect. The bigger reason is that the person who is sacrificed must be completely willing. With the mental state of the Uchiha after being stimulated to open his eyes, it can only happen between brothers. It is probably difficult for people of the same clan to be willing to sacrifice themselves for others. What's more, the base number of Mangekyo is too small. It is normal that no one has discovered that this answer is only an approximate solution rather than a standard solution."

Wang Jie, who was observing the whole process, saw the changes in the two people and quickly came to a conclusion. Although he still didn't know how the change from kaleidoscope to eternal kaleidoscope came about, he had a rough guess about the principle.

"No change?" X2

Uchiha Mingguang and Uchiha Tokuma both showed disappointment in their eyes.

Wang Jie took the two of them into the Shenwei space before speaking: "Don't be discouraged. Although the experiment of exchanging eyes between you two failed, the reason has been found. The solution is to continue to level up and provide mental power. I estimate that when the mental power of the two of you can reach twice the mental power value when you open the Mangekyō, you can successfully evolve into the Eternal Mangekyō by exchanging eyes. After all, I have evolved the Mangekyō by exchanging my left and right eyes, so relax and find a chance to change back later. I will take you back first. It has been 7 days. It's time to take you back to Konoha to report safety."

Wang Jie’s words were not only addressed to the two of them, but also to the other Uchiha. After all, everyone was very concerned about this issue.

Afterwards, he ignored the visible disappointment of the other Uchiha and their immediately burning hope, and left the Kamui Space directly and went back to the rental house to sleep. However, he seemed to have forgotten that because of staying up late to fight the BOSS, there was a one-day time difference between the two worlds, which resulted in the information inadvertently spoken by these Uchiha after they dispersed having a time difference with others, but this was a minor problem and did not need to be taken too seriously.

At least there is no need to worry too much about it now, because when he brings these sixteen Uchiha back to the clan, he will immediately convene a clan meeting. When all the Uchiha with three magatama or above see the sixteen pairs of Mangekyo, you can imagine how lively the scene will be. Who cares how many days they disappeared, does it matter whether it is 6 days or 7 days?

Does it matter whether it takes 6 days or 7 days to go from a normal Sharingan to a Mangekyō Sharingan? Who the hell cares about this question? They don’t even think it’s important how they did it. There are people in the Uchiha clan who chose to kill their own relatives in order to open these eyes. Now they just want to know if I can do it too! ?

"Okay, be quiet."

Even if Fugaku and the elders shouted desperately, the enthusiasm of the Uchiha could not be suppressed, and it was instantly quieted by Obito's words. Of course, the enthusiasm was already there. All the Uchiha who did not have Mangekyō were staring at Obito with enthusiasm, including Fugaku and the elders. Even Elder Setsuna, who felt that he had only a few days left to live, showed his desire with the enthusiasm in his eyes without any concealment.

"Ahem, well, we can't all disappear at once. Someone has to go to work in the security department, and someone has to stay to take care of the business outside. Chief Fugaku, you two should discuss making a list. Under the premise of not arousing suspicion from the outside world, we should arrange them in batches in an orderly manner. Adults will be given priority, and minors can be put a little later. From now on, I, the Uchiha, will no longer have to send children to the battlefield. From now on, no one can speak loudly to us, not even the Senju. I say that."
