Hokage: Save The World

In the root laboratory, Naruto took out the Mangekyō Sharingan containing Uchiha Fugaku from the petri dish, and carefully placed the Mangekyō on the experimental table.

Although Uchiha Itachi still has a pair of spare ones, they are not as good as the one in front of him. As long as Sasuke successfully fuses them, the eternal Mangekyō can be successfully manifested.

Six or seven years have passed since the night when Uchiha was exterminated. Naruto kept this pair of Mangekyō for so long just for this moment. The pair in Sasuke's eyes, plus the pair on the experimental table, will wait a little longer. Also acceptable.

Soon Naruto changed his clothes and prepared for surgery. Although this surgery was simple, it was worth doing by Naruto himself. If any problem occurred during the fusion process, Naruto could solve it in time.

Don't underestimate his medical ninjutsu. Regardless of his physical condition, Naruto's own medical ninjutsu is also very good. He studied under Tsunade and stayed in Konoha Hospital for a long time, so for this small eye surgery, Naruto Still quite experienced.

"Naruto, who does this Mangekyō belong to? Is this the method you said?" Sasuke was curious and looked at the Sharingan in the petri dish at an extremely close distance.

"These are the eyes of your father, Uchiha Fugaku." Naruto explained to Sasuke.

"My father?? Father, he also has Mangekyō?" Sasuke looked at Naruto in disbelief.

"Your father was killed by Uchiha Itachi voluntarily, so no conflict broke out at that time, and he died under Uchiha Itachi's knife without any resistance.

The way to restore Mangekyō's light is to transplant a blood relative's Mangekyō. "Naruto placed the Petri dish in front of Sasuke's eyes, and Uchiha Sasuke's Mangekyō opened unconsciously. The two pairs of Mangekyō Sharingan just looked at each other.

Vaguely, Naruto seemed to see two pairs of Mangekyō fused together through the glass bottle. It was a complex and strange pattern.

"Has it started again?" After Naruto gained the ability to see into the future, he often saw some fragments of the future. Even if Naruto didn't actively use it, he could still see a little bit. This time he saw the pattern after Mangekyō fusion. This is This means that this surgery has a greater chance of successful fusion.

After all the preparations are done.

In an instant, Uchiha Sasuke was lying on the experimental table.

"Sasuke, relax, this is just a minor surgery. When you wake up, you will gain unparalleled power." Naruto comforted, seeing Sasuke's nervousness.

As the anesthetic took effect, Sasuke's trembling body slowly calmed down. Only the slight rise and fall of his chest showed that he was still alive. Sasuke had fallen into a coma.

Starting the transplant, Naruto removed Sasuke's nearly blind Mangekyō and placed it in a petri dish. Naruto breathed a sigh of relief until both eyes were removed.

In fact, Naruto doesn't need to be so nervous. If there is a problem, just use his own Chakra to repair it. Uchiha Fugaku's Mangekyō is transplanted into Sasuke's eyes, and the nerves gradually connect.

At the moment of connection, a strange pupil power stimulated Sasuke's brain, causing Sasuke who had lost Mangekyō to generate new pupil power. Naruto opened his white eyes and observed carefully.

He could see clearly that through the stimulation of a Mangekyō similar to Sasuke's, the new pupil power in Sasuke's brain and the pupil power in his eye sockets were merging with each other.

At the same time, Indra's Chakra, which appeared during the fight with Naruto, appeared again and was constantly participating in the fusion process of eye power, and Sasuke's Chakra also became more textured, and the cold taste became heavier.

The transformation of the Eternal Mangekyō is not only the transformation of the eyes, but also the Chakra and spirit of the Host are transformed during the fusion process, becoming more suitable for his use. Even if someone else transplants the Eternal Mangekyō, they will become different because it is not their original one. More difficult to use.

Moreover, it exerts a strong mental pressure on the user, and those who are not strong enough will still be burdened by using the advanced Mangekyō.

Just like Obito transplanted Rinnegan, the Obito Uchiha tribe and Hashirama cells could only withstand the power of one Rinnegan, and they were almost swallowed by the Rinnegan.

During the Three Magatama period, Kakashi could still maintain the consumption of Sharingan, but was still in a state where Chakra was being slowly consumed. By Mangekyō, when Kakashi used Kamui for the first time.

It takes several minutes to continuously condense Chakra before it can be used. Although Kakashi's Chakra increased as he grew older, he still consumed Chakra and died in the battle with Pain.

Even if a genius like Kakashi uses a Mangekyō, it will become like this. Kakashi's Chakra amount is already too much, but he does not have Uchiha bloodline. This shows how difficult it is for people without Sage of Six Paths bloodline to use related things.

If you give eternity to Kakashi, he may only be able to use it once, and then the Chakra will be consumed directly.

Related to one's own bloodline, the stronger something is, the harder it is for outsiders to use it. It's not that they are not strong, but the limitation of the thing itself.

As the surgery ends, the effects of the anesthetic wear off.

But the fusion of eye power is still going on, and it looks like Sasuke will have to wear a bandage for a while.

Sasuke woke up.

Now Sasuke felt that the Chakra in his whole body was a little more active, and a cool feeling flowed all over his body along with his eyes, but his eyes could still only feel a blur of light.

He stepped off the test bench, and with his years of ninja skills, he quickly became familiar with this state of blindness, and slowly sensed the surrounding situation through Chakra step by step.

Putting on the clothes based on his own memory, although he is now directly blind, it is much better than Mangekyō's blurred vision.

"You're awake, Sasuke, don't move." Naruto sensed that Sasuke's Chakra was moving, and it was about the same time. As soon as he came in, he saw Sasuke moving around in the laboratory.

How can a person who has lost his sight touch the things in the laboratory at will? What if it is broken? The money is small, but it takes time to make a new one.

"Naruto" Sasuke suddenly became happy hearing Naruto's voice.

"I feel very good now, tell me if the transplant was successful."

"Yes, the transplant was successful, but it will take time for the pupil power to fuse, so you cannot use your eyes during this period and you need to be patient."

"During this period, your Chakra and body will have certain reactions. These are normal reactions. There is no need to worry." Naruto asked Sasuke to calm down and not worry about his own changes.

For eternal fusion, this is also quite valuable experimental data, which can further observe the branch bloodline of Ōtsutsuki.
