The Goal of This Plan Is to Gradually Get Teacher Used to His New Identity

The soul was a wondrous thing.

"In the past, there was no way to prove the existence of the soul. Although there was the famous Twenty-One Grams Theory, it was never widely accepted." Kenichi Amamiya sat in his home, recording his thoughts in Chinese characters.

Kenichi Amamiya wrote some things down in Chinese characters. The Naruto World knew nothing about Chinese characters, so they could be considered an absolutely secure code.

The Twenty-One Grams Theory had once been hugely popular in his previous life, and Kenichi Amamiya knew of it as well. However, it had never been scientifically proven. People believed the missing twenty-one grams were merely exhaled gases or something else.

"But souls exist here, and it seems they can even be observed with the naked eye. Yet souls apparently do not reincarnate. They simply remain in the Pure Land." Kenichi Amamiya fell into thought.

If this discovery were brought into his previous life, it would absolutely shock the world and might trigger a whole series of problems.

Who had no regrets? Who did not long to see their deceased loved ones again?

When death was no longer the end of life but the beginning of another journey, what consequences would it bring?

Kenichi Amamiya shook his head. Philosophers should be the ones worrying about such questions. Right now, he was more concerned with something else.

"If the soul can control the body, then conversely, can the body affect the soul?" Kenichi Amamiya thought of his teacher, Orochimaru.

Could he influence the soul through the body and gradually make his teacher think and behave more like a woman?

Kenichi Amamiya was very curious.

Besides, after Teacher Orochimaru defected from Konoha, his personality had become more extreme as well. Could that have been caused by his soul being affected by his body?

"Still, I'll probably have to conduct this research myself. If Teacher finds out..." Kenichi Amamiya shuddered.

His teacher had a strange personality. He was gentle and caring toward Kenichi Amamiya, his disciple, but he was also extremely cold-hearted.

Gentleness and coldness did not seem like traits that belonged in the same person, but that was truly how Kenichi Amamiya saw him.

His teacher was always stern with his students, demanded much from them, and punished them harshly. But he was equally generous with rewards, and even now, he had always kept his word.

He had fulfilled every promise he had made to Kenichi Amamiya.

Kenichi Amamiya silently tore out the page containing that idea and threw it into the stove, where it burned to ashes.

He had never underestimated his teacher. Orochimaru was intelligent—exceptionally intelligent—or else he could never have become one of the Sannin. If his teacher learned Chinese characters in the future, there would be serious trouble.

Still, Kenichi Amamiya decided to try the experiment. Perhaps it would yield some unexpected gains while also deepening his understanding of souls.

The next day, Kenichi Amamiya went to watch the Third's inauguration ceremony.

"His arm was only transplanted yesterday, and today he's announcing that he's Hokage again?" Kenichi Amamiya clicked his tongue. The Third really could not wait.

But considering Danzo's watchful ambition and the calls for Orochimaru, the Third's urgency was understandable.

Besides, with his prestige at its peak, it was only natural for him to strike while the iron was hot and immediately announce his return as Hokage.

The village also truly needed a Hokage to take office quickly and reassure the people. It was also a response to the outside world. Yesterday's incident had caused too great a commotion; it would be troublesome if the other ninja villages tried to take advantage of the chaos.

"...Kenichi, let's go. Today's testing isn't finished yet." Orochimaru stood with his arms folded, watching with an indifferent expression. Once the Third began speaking about the Will of Fire, he turned and left, taking Kenichi Amamiya with him.

Kenichi Amamiya silently followed his teacher. He did not want to listen to that Will of Fire speech either. The Third had given it so many times that he could recite it by heart.

After following his teacher into the laboratory, Kenichi Amamiya became much more serious. He was actually getting tired of conducting experiments for Root. They were boring, and progress was painfully slow.

If not for the money, Kenichi Amamiya suspected his teacher would not want to do it either. But his teacher also seemed to be slipping in some personal work, using Root's materials and funding for his own research.

There were some experiments his teacher would not let him touch at all. Of course, such experiments were rare. Kenichi Amamiya suspected they involved the unique ninjutsu, Living Corpse Reincarnation.

"Kenichi, I have a research assignment for you." His teacher changed into another outfit and put on Gloves as he spoke.

Kenichi Amamiya immediately stood at attention.

"This task is simple. Study how to make the proliferation of those cells stable and controllable." Orochimaru assigned the task with a serious expression. Kenichi Amamiya froze when he heard it.

"Teacher, you mean..." Kenichi Amamiya was somewhat uncertain.

"Just complete the research. If you succeed and produce results, this may become a discovery that shakes the world." Orochimaru narrowed his eyes and said no more.

But Kenichi Amamiya understood his teacher's intentions. His teacher must have had thoughts similar to his own.

As everyone knew, Cancer Cells were cells that had broken through their limits. As long as they had sufficient nutrients, they could proliferate almost indefinitely, and no upper limit had yet been observed.

Could Cancer Cells be the key to human evolution?

Or the key to immortality? It was simply that no human could currently withstand the damage and plundering Cancer Cells inflicted upon the body.

Cancer Cells: Hey, I want everyone to live forever too, but you all collapse before I can even get going.

"Understood, Teacher." Kenichi Amamiya nodded. This experiment would not be too troublesome.

During his research over this period, Kenichi Amamiya had discovered that Cancer Cells and First Hokage's Cells possessed very similar traits. One could say that Hashirama Senju was like an oversized human Cancer Cell. His cells possessed immense vitality, and ordinary people could not withstand them either.

After discovering this trait of First Hokage's Cells, Kenichi Amamiya even began to wonder whether the First was still human. How could the cells in his body be so monstrous?

The First's cells were like Cancer Cells that each performed their own function while also being able to proliferate infinitely, and they had no apparent side effects. He seemed capable of immortality.

But the First was dead, though the exact manner of his death remained uncertain.

So whether the First could truly have lived forever was still an unknown.

"I hope Teacher can leave soon. There are too many restrictions on conducting experiments here." Kenichi Amamiya shook his head. Still, that day was probably close. His teacher's intentions had become very clear.
