Naruto: The Strongest Kakashi

After Kakashi returned, the hostility inside the Anbu all subsided within a few days, which shows Kakashi's powerful influence in the Anbu.

In the Hokage Tower, Tsunade sits on the Hokage's seat and opposite her is Sandaime Hokage.

Tsunade smiled and said: "Sarutobi-sensei, you are right. When Kakashi comes back, those restless Anbu immediately calmed down."

Sandaime blow his pipe and said with a smile: "Haha, that's natural. After all, apart from me, only Kakashi can convince these people from Anbu. Now that Kakashi is back, the grievances in their hearts naturally disappeared. Don't worry about it. Their feelings for Kakashi are built up bit by bit. And you have been away from Konoha for a long time."

"It doesn't matter to me. After all, I originally didn't have much interest in the position of Hokage. Kakashi is indeed a good candidate. But, I don't know why he refused to take over the position of the Godaime Hokage." Tsunade said curiously.

Hearing this, Sandaime sighed and said: "Kakashi is having a bad feeling from an organization called Akatsuki. He asserts that this organization will cause a huge storm in the future, so he needs time to deal with this organization."

"Akatsuki? I have heard that it seems to be a mercenary organization that obtains funds by hunting down Shinobi like bounty hunters. Now it seems that they are not that simple."

"Yes, it's not that simple. I have also investigated these people. They all seem to be composed of S-rank missing-nin, and Orochimaru is also in this organization."

"Orochimaru?" Tsunade muttered, remembering the man that resembled snake.

"Well, the gathering of such a group's tasks will never be for the purpose of making a living, so Kakashi's concerns are not unreasonable. Let Kakashi deal with this matter."

Tsunade nodded. She knew Kakashi's ability. If even Kakashi could not deal with this organization, then, no one in the world could deal with this organization.

For the time being, the talk about the Akatsuki's incident was finished. Tsunade and Sandaime then talked about the village again, and after a while, Sandaime left.

After all, the Hokage at this time is Tsunade, and she has a lot of things to do.

Sandaime is now only an elder, so he can relax.

There were a lot of things in Anbu piled up, so Kakashi had to deal with it for three days before he had time to go home and slept well.

After waking up, it is already in the middle of the night.

"Ah, it's a good night's sleep."

Kakashi stretched out his body. He then took a seal scroll with the word "eye" written on it from his ninja bag.

Kakashi narrowed his eyes and muttered: "The time is almost here, it's time to integrate it."

As soon as the voice fell, Kakashi's figure disappeared from the room, and in the next moment, Kakashi appeared in a secret room inside Ochagakure.

This secret room is placed under Kakashi's room in Jinjin Village and it is highly concealed.

No one knows about this room except Kakashi and Shisui.

And Shisui also hardly come to this place.

If Kakashi wants to integrate Mikaze's Sharingan, he needs a quiet environment.

The integrating surgery does not require much time, but the time until the integration completed cannot be estimated.

After all, Kakashi is not someone from the Uchiha Clan. So he is afraid that the time it takes to be used to it will only be known after integrating it.

"I hope it won't be too long."

Kakashi murmured, and then he formed a hand seal.

"Kage Bunshin no Jutsu!" (Shadow Clone Technique)

It is obviously extremely difficult for one person to change his own eyes. Therefore, a shadow clone is needed to aid him.

As for the method of integrating the Mangekyō Sharingan, Kakashi has learned from about it from the stone monument of the Uchiha Clan.

Although the stone tablet has been changed by Black Zetsu, the method of integrating the eternal Mangekyō Sharingan is not changed.

The shadow clone looked at Kakashi, nodded, and then placed one hand on the seal scroll.

"Kai!"

With a bang, a bottle of green liquid appeared in front of Kakashi.

Inside the green liquids, there are two scarlet Sharingans floating slowly.

"Success or failure depends on this."

Kakashi took a deep breath, lifted the forehead protector from his left eye, and at the same time, lifted the Four Symbols Seal on his left eye.

Inside his scarlet Sharingan, the black dart pattern slowly spins and seemed to be somewhat excited.

The field of vision of Kakashi's left eye is already blurred at this time. And the eye is almost blind.

"Okay, let's start."

Upon hearing the words, the shadow clone took out the left eye in the green liquids. As for the remaining right eye, it was still in the bottle, and at the same time it was sealed into the scroll again.

Kakashi only intends to integrate his left eye to achieve the eternal Mangekyō Sharingan this time. As for the right eye, it is temporarily out of Kakashi's consideration.

There are two reasons for this.

One is that after the integration of the Sharingan, there will be a period of recovery for the eyes, and during this time, the Sharingan cannot be used.

If he transplants both of his eyes, it does not matter for his left eye as it is originally sealed and covered with his forehead protector. But as for the right eye, the problem is big.

Kakashi can't change the Sharingan back to normal eye. When his right eye turns into Sharingan, people would know that he got new Sharingan.

Therefore, transplanting his right eye can only be temporarily put down.

After the left eye finished integrating, he will consider it again.

The shadow clone's right hand is covered with green Chakra, he then wrapped Mikaze's left eye in it, and then his right hand slowly approached Kakashi's left eye.

Kakashi didn't have any fear and just stared straight into that eye.

The shadow clone also covered his left hand with green Chakra and placed it on Kakashi's head.

Mikaze's left eye gradually touched Kakashi's left eye.

Next, an incredible scene happened!

After Mikaze's Sharingan touched Kakashi's left eye, a shattering sound rang.

Immediately afterwards, Mikaze's Sharingan shattered like glass!

Then it slowly enter Kakashi's left eye!

"Argh!"

The intense pain caused Kakashi to scream involuntarily.

The pain is like stabbing glass shards into his eyes!

Kakashi gripped his clothes tightly and clenched his teeth.

The intense pain lasted for about half an hour before the integration of the eye finally ended.

Mikaze's left eye had completely disappeared at this time, and it looks like it had never existed.

But blood was dripping on Kakashi's left eye at this time!

However, the painful expression on Kakashi's face has disappeared and replaced with joyful expression.

"Success! This feeling! I can feel that Mangekyō Sharingan's power is being absorbed by my left eye." Kakashi joyfully said.

The shadow clone took out the bandage that was prepared in advance, and wrapped Kakashi's left eye with it. The blood then slowly stopped.

"This feeling is so wonderful, the pupil power of the two is constantly merging, and new terrifying power seems to be slowly awakening."

Kakashi exclaimed.

But soon, Kakashi frowned again.

"This integration speed seems to be a bit too slow."

Kakashi could feel that the integration of the two eyes at this time is at the speed of snail crawling.

'Is it because I don't have the Physique of the Uchiha Clan so that the speed of the integration is slow?' Kakashi secretly thought.

And at this moment, a sudden change occurred!

Kakashi suddenly felt a pain in his left eye. He covered his left eye with one hand, and put the other hand on the ground.

"Damn it! Sure enough, there is still rejection!"
