Naruto: The Strongest Kakashi

"Then, the problem before has been solved?" Kakashi asked happily.

Shisui shook his head and said: "No, it hasn't been solved yet."

"It can't be solved?" Kakashi asked with some confusion.

"The Hashirama's cells are the cells of the Shodaime Hokage, and they are very domineering. Their repulsive power is not something that can be completely eliminated by the research itself. Even if it is possible, it cannot be achieved by Ochagakure's medical level."

"Then for you to ask me to come over, did you find another way to solve this problem?"

Shisui smiled and nodded. "Yes, I found something about this problem. This kind of repulsive force is not obvious on my body. Or rather, it is extremely weak. At first I thought it was due Orochimaru's skill, but later discovered that although the left hand made by the Orochimaru was excellent, the rejection drawback still exist. But for to not reflected in my body, there is only one reason, that is because of Uchiha Bloodline."

Shisui said as he closed and opened his eyes, and the scarlet Sharingan emerged instantly.

"Uchiha Bloodline?"

"Yeah, as these repulsive forces cannot be eliminated, we can only find a way to offset it. And Uchiha Bloodline is the way."

Kakashi was stunned.

With how powerful Senju Hashirama's Sage body is, it is true that only Uchiha Bloodline can offset it.

Danzo's right hand is made using the principle of Hashirama's cells and Sharingan mutual restraint.

However, this method has certain drawbacks, that is, when they are out of balance, it will cause great damage to the body.

However, if the body has strong Uchiha Bloodline, this drawback is insignificant.

There has never been a backlash from the Uchiha who was transplanted with Hashirama's cells.

Needless to say, Madara awakened the Rinnegan directly with the help of Hashirama's cells.

As for Obito, half of his body is created from Hashirama's cells, but there is no backlash, and the power of his Kamui was developed to the peak.

Only Danzo, who used both Sharingan and Hashirama's cells, got the backlash.

Therefore, it can be concluded that Uchiha Bloodline and Hashirama's cells can be integrated safely.

"Do you think Itachi's Uchiha Bloodline can suppress Hashirama's cells and counteract this side effect?"

"Yes, if my prediction is correct, after Hashirama's cells enter Itachi's body, the repulsive forces would be suppressed by the Uchiha Bloodline. At that time, the backlash should not exist. Of course, I don't know how the situation will actually be. I would only know after trying it."

"Isn't it risky?" Kakashi frowned.

Although it is true in theory, if a problem actually occurs, it may not be so easy to solve.

"Itachi's body can't hold for much longer. Recently, Itachi has been looking for drugs to suppress his illness, but those drugs are not very effective. It can only delay the inevitable for one or two years, and they will eventually cause some damage to Itachi's body. If he continued to use it, then maybe even Hashirama's cells won't work anymore."

Hearing this, Kakashi was silent for a moment, and then said: "It seems that this is the only way. Have you notified Itachi?"

"Yeah, I have already made an appointment with Itachi, but Hoshigaki Kisame around Itachi is a troublesome guy. Although he is said to be his partner, he is actually someone that masked man sent to monitor Itachi."

"Don't worry, with Itachi's ability, it's not a hard thing to get rid of Kisame Hoshigaki and meet with us."

"Of course I know that. It's almost the time, let's go. I have already placed your Flying Thunder God Technique's mark at the agreed location." Shisui said.

Hearing this, Kakashi nodded. Holding Shisui's shoulder with one hand, Kakashi used Hiraishin no Jutsu (Flying Thunder God Technique) and the two disappeared from the lab.

Somewhere in the Land of Fire, Shisui and Kakashi suddenly appeared.

"It's here," Shisui said softly.

Kakashi looked at all around and saw that it is a forest with a high mountain behind him and a cave under the high mountain.

Not long after the two arrived, a dark figure came from a distance and landed in front of the two.

A big black robe with red clouds patterns on it, scarlet eyes, and two deep lines on his face.

His face was slightly pale.

This person is Uchiha Itachi!

"Itachi," Shisui said softly.

Kakashi also looked at Itachi.

Itachi looked at the two people in front of him, and smiled slightly.

In this chaotic world, he only has these two friends in front of him.

"Shisui, Kakashi-senpai. Is there anything you need to call me over this time? Kisame is very keen, so I can't stay here for too long."

"Itachi, how is your body?" Shisui asked.

"It's okay." Itachi said lightly.

Kakashi shook his head helplessly, and said, "Itachi, you sure love to lie so much. Just look at your face, how is that okay."

"Kakashi-senpai, I just didn't have a good rest recently."

Itachi's voice was still so calm, and people couldn't hear much emotion from it.

"Okay, Itachi, don't force yourself. I know from Nekobaa, you are asking her to find medicine, right?" Shisui said.

Hearing this, Itachi also knew that his physical condition probably couldn't be kept secret.

"Sorry, I don't want you to worry about it."

Shisui patted Itachi on the shoulder, and said with a smile: "Itachi, you sure are still the same as before, always like to carry everything by yourself. Don't worry, Kakashi-senpai and I have found a way to treat you."

Itachi was stunned for a moment. He didn't expect that not only Shishui and Kakashi knew his physical condition, they also found a way to treat it.

There was a slight warmth in Itachi's heart at this moment.

This feeling of being taken care of by others makes Itachi very happy.

Shisui took out syringe containing the green liquid and said, "This is the solution of Hashirama's cell that we developed based on Hashirama's cell in my left hand. It has strong vitality and should be able to offset your worsening physical condition. If it goes well, your Mangekyō Sharingan should also be able to improve and also restore a certain degree of your vision."

"Hashirama's cell?"

"Yeah, Itachi, try it. Although there are certain risks, it is much better than the medicines you are using now. We don't want your body to collapse so quickly, after all, there are still many things that have not been done." Shisui muttered.

After hearing Shisui's words, Itachi pondered for a moment, and finally nodded.

Seeing this, Shisui was overjoyed and said, "Okay, let's get started."

Itachi nodded and pulled up his sleeves, revealing his thin arms.

His arm that has not been exposed to sunlight for a long time looks a little pale.

Shisui picked up the syringe and stabbed it into Itachi's arm!
