Hashirama: An eldest brother is like a father. I'll show you my authority as your big brother!

The last infant raised from an early age with Hashirama cells was Yamato, but there had been several infants in his batch who received those cells.

Yet in the end, Yamato was the only one who survived.

So Hashirama understood that his cells were extremely dangerous. Recklessly implanting them into others would only get those people killed.

Even artificial humans were no exception. In Hashirama's eyes, once those artificial humans were born into this world, they had souls and lives of their own.

"Calm down, big brother! Calm down! I was only giving an example, just an example!"

Tobirama hurriedly explained.

Only after hearing that did Hashirama breathe a sigh of relief.

Tobirama continued explaining.

"Based on past experimental data, we've already established one thing: big brother is a unique existence. Whether we transplant his cells or use them directly for cloning, we can't create another person as powerful as him.

In fact, most test subjects who receive his cells die, while the clones ultimately turn into trees, unable to survive as humans.

That's why research into his cells has already been banned by the Scientific Management Department.

And the artificial human I created is simply an ordinary artificial human modeled after me."

Izuna scoffed disdainfully.

"Tch, I thought there would be something special about him. So he's just an ordinary artificial human.

Then he's a lost cause. You're already no good, Tobirama Senju, so an artificial human modeled after you would be even worse."

But rather than getting angry at Izuna's words, Tobirama gave a cold laugh.

"Hmph, foolish Uchiha Izuna. That's where you're wrong.

Kekkei genkai are certainly powerful, but they aren't the only option."

"What do you mean?"

"Hehehe, you don't understand, do you? Have you ever heard of a natural sage body?"

"A natural sage body?"
