Sixteen Years Old, The Fourth Generation of Mizukage

The next day, Itachi Uchiha walked alone into the library where Rei Kaguya's historical restoration and research course group was located, with a resolute expression on his face.

And there, he saw Jiraiya who was sorting out the scrolls of literature with a sad face, and Kakashi Hatake who was looking through the notes left by Kaguya Rei, sometimes frowning, sometimes relaxing.

With the comfort of Senju Hashirama, Tsunade walked into the door of the Kirigakure Ninjutsu Development Department with the Yin sealing technology in her mind, and through the connection with Kirigakure, she successfully entered the Ninjutsu Development Department. I got my own independent office and a laboratory of considerable size and facilities.

The remaining Konoha students, mentors and guards each returned to the positions arranged for them by Kirigakure, and began to be more serious and experience the differences in life and study between Kirigakure and Konoha more deeply.

As for Senju Hashirama who was reincarnated by the dirty soil?

After he wandered around all the areas of Kirigakure that were open to the public, and carefully observed and asked about the production and life of the passing residents, he plunged into Orochimaru's laboratory, and then participated with great interest. Go into your own cell-related experiments.

"Oh, I really can't believe...I am obviously dead, but some of my body's physical cells can still exist in such a healthy and over-the-top way until now, and even grew into my own appearance..."

Across the petri dishes with carefully set parameters, Senju Hashirama, who was reincarnated from the dirty soil, looked at the bodies that were exactly the same as his own, and sighed sincerely:

"If I hadn't survived this time, I wouldn't have known that such bizarre things could exist in the world."

"Honestly, compared to the weird activity displayed by the cells you left behind, I still think your current attitude is more bizarre."

After finishing his teaching in the ninja school, Yakushi Kabuto, who came to give Orochimaru a hand, pushed up his glasses and complained in a low voice:

"How can there be a person like you who can still laugh and laugh when he sees his body being used after death..."

"That's true, but if you really want me to remain serious in front of a face that looks similar to mine after falling asleep, it's not that easy to do..."

Senju Hashirama shrugged, then turned to look at a large opaque petri dish specially isolated in the laboratory, and asked curiously:

"What's inside that container? I remember when I came here two days ago, there was still no one working in that container, right?"

"She is the wife of the Fourth Hokage. She had the Nine Tails removed from her body and fell into a state of near-death. Although Lord Orochimaru temporarily suppressed her vitality by transplanting your cells into her, It is constantly weakening, but because your cells are also irresistibly erosive, every once in a while, she has to come over to remove the transplanted column cells and replace them with new ones to prevent herself. Over-eroded by your cells and completing the process of making up for the missing vitality.”

Kabuto Yakushi walked to the side of the large petri dish, looked at the parameters and experimental records set on it, and expertly pressed the button that dispensed the nutrient solution. He turned to the surprised Senju Hashirama and said:

"Please step aside for a moment. Her treatment this time has ended..."

"Oh, alright."

Senju Hashirama decisively retreated to an area where he could not see this side, while Yakushi Kabuto walked to the large petri dish with a clean hospital gown, casually pulled down the surrounding curtains, and faced Looking at Uzumaki Kushina who had just slipped out of the petri dish, he asked casually:

"How do you feel this time, Mrs. Kushina? Is it better than before?"

"For now, it's getting better."

Uzumaki Kushina, whose face was still not healthy, but finally had some blood, cleaned the nutrient solution from her body, put on the hospital gown handed over by the pharmacist Kabuto, and said helplessly:

"However, can you think of a way to prevent the Hashirama cells transplanted into my body from growing up like the first Hokage? You know that every time I look in the mirror, I can see something on my back. Seeing the face of the first generation of adults, how devastating is this kind of thing?"

"Well, there is no solution..." Kabuto Yakushi was busy observing the Hashirama cells taken out of Kushina Uzumaki's body, recording their various parameters after testing, and said without looking back: "But Mrs. Kushina's body should not have recovered to the point where she can withstand that method..."

"What is the solution?" Uzumaki Kushina asked unwillingly.

"Use the Yondaime-sama's cells to erode the Hashirama cells of the First Hokage. Without external interference, as long as the ratio is controlled, a relative balance can be formed between them. Before the Yondaime-sama's cells undergo complete apoptosis, , Hashirama's cells will no longer grow in the direction of condensing into the First Generation Hokage."

Kabuto Yakushi shrugged and gave an answer that Kushina Uzumaki could never accept.

"...You, at such a young age, why are you like Orochimaru, able to treat the human body as a mere container without taking it seriously?"

Uzumaki Kushina didn't know whether it was fear or some other reason, she hugged her arms tightly and asked Yakushi Kabuto with a complex expression.

"Because the human body is indeed just a container and skin. Replacing and strengthening human organs and limbs that are missing, diseased, or congenitally deficient is the inevitable research direction of medical ninjutsu in the future."

Kabuto Yakushi calmly put away the experimental data he had written, turned around and made a gesture of invitation to Uzumaki Kushina:

"According to Orochimaru-sama and my calculations, after this treatment, you should be able to recover to the point where you can move on your own. The interval between the next replacement of Hashirama cells will also be extended to about a month... Go out first Let’s take a walk and see if there are any mistakes in the calculation results we obtained by analyzing the cells of the two Uzumaki clan members.”

"A month...?"

Hearing this number, Uzumaki Kushina, who had been suffering from the symptoms of lack of vitality for a long time, couldn't help but her eyes lit up. She took a deep breath, stepped out and walked out in a hurry, hoping to survive in her body. Before you start to feel weak, experience the feeling of walking freely and moving freely again.

Then, after walking past a Petri dish containing Hashirama's cells, she saw a black-haired man wearing an ancient armor from the Warring States Period. He looked a bit, oh no, very familiar.

Damn, I obviously reserved a lot of time for myself, but after leaving time, I couldn’t help but write more in the first chapter, and then I started racing against the deadline again in the second chapter...
