Konoha's entry is ninja!

After Danzo left, Orochimaru looked at Hoshita Shuichi and smiled meaningfully: "Shuichi-kun, you did not disappoint."

"But being a double agent is not easy."

Hoshita Hideichi said: "Who in this world can understand Danzo better than the Third Hokage?"

Orochimaru was startled for a moment, then nodded in agreement.

Hoshita Shuichi turned to look at Orochimaru and said meaningfully: "As long as I put the Third Hokage and the interests of the village first, no one will doubt my loyalty."

Of course Orochimaru could understand Hoshita Shuichi's underlying meaning, and smiled softly: "In terms of relationship, the relationship between me and the third generation is deeper than that between you, Shuichi-kun."

He has put Shuichi Hoshita on a relatively equal footing, without any condescension.

In the ninja world, strength is always the best way to win the respect of the other party.

Turning around and walking out, Orochimaru continued: "Shuichi-kun's ideal is to master all types of ninjutsu?"

Hoshita Shuichi followed one step behind: "If possible."

"However, human life is limited after all, and from ancient times to the present, various ninjutsu and secret techniques have emerged in endlessly. If you want to explore them thoroughly, I may not be able to do it in a lifetime."

Orochimaru felt the same after hearing this: "That's true."

But then he changed his voice and said with temptation: "But Xiuyi-kun's knowledge is too little. There are many beings in this world with extremely long lifespans?"

Hoshita Shuichi pretended to be ignorant: "Master Orochimaru, are you talking about those people with special physiques?"

"I've heard that the Uzumaki clan has an extremely long lifespan."

Orochimaru turned to look at Hoshita Hideichi and said with a smile: "No, even the Uzumaki clan is only a mortal."

Xingxia Xiu nodded and thought: "Indeed."

"As long as we are human, we cannot escape the limit of the number of cell divisions."

"This is also why among medical ninjutsu, the technique that causes cells to divide rapidly will cost lives."

"I have also studied many other animals, and even flesh and blood have no way to escape this shackles."

Of course, there is a difference between cell division, cell renewal, and metabolism.

Like Tsunade who uses chakra to keep herself in her thirties, this is not just for beautiful appearance.

What's more important is actually using chakra to keep cells alive, or to slow down the rate of cell aging and extend the cell replacement cycle, thereby reducing the number of cell divisions and extending lifespan.

But this obviously cannot make people live forever, let alone like Kaguya Otsutsuki and Black Zetsu.

Even if it takes 500 years, there is no way to do it.

Because chakra ultimately originates from the body and spirit, organ aging is irreversible, and the consumption is very small, but it always exists.

"Immortal magic..."

Hoshita Shuichi's thoughts wandered, and he thought of the sage mode, and then thought of Kabuto Yakushi's state.

Then I thought of Jugo again.

Both of these people can save people through cell transfer, and they saved Uchiha Sasuke.

"In the ninja world, the only options for immortality currently seem to be divine trees and celestial magic..."

To be honest, it was the first time for Hoshita Shuichi to think about the issue of immortality.

It's just that he is too young.

All he had thought about before was how to save his own life.

Orochimaru glanced at Hoshita Shuichi's thoughtful face, and saw the twinkling light in the latter's eyes. He was too familiar with this state.

"It seems that Shuichi-kun has gained a lot. Tsunade has taught you a lot."

Orochimaru smiled.

Shuichi Hoshita said modestly: "It's not really a gain, it's just a small idea that can slow down cell aging and extend the cell division cycle."

Orochimaru was very interested when he heard this: "Oh?"

"May I know?"

"Of course, I will repay you with something of equal value."

This can be said to be a perfect match. He showed off his talent and immediately smiled and said: "Of course there is no problem with this. This is not something extraordinary or confidential."

After saying this, Hoshita Xiuichi came up with his ideas one by one.

Orochimaru listened very carefully and even made suggestions on some details. Although this level of things was not what he wanted, there were some things in it that might be useful?

And it is.

There are still many things worth learning from Hoshita Shuichi's set of assumptions.

After listening to it, Orochimaru smiled and said: "It is indeed a very interesting idea and very groundbreaking."

"Shuichi-kun is truly a genius praised by both Tsunade and Jiraiya."

Hoshita Shuichi was a little embarrassed after being praised.

However, he had developed a thick skin and did not blush. Just as he was about to speak, Orochimaru stopped and said, "We're here!"

Xingxiaxiu took a look and saw an entrance in front of him.

Did you bring yourself to the experimental base?

Hoshita Shuichi looked around: "Lord Orochimaru, is this the root's secret base?"

Orochimaru smiled and said, "No, this is where I do research."

As he said that, he led Xiuyi Hoshixia from the entrance into a long corridor.

Hoshita Shuichi could feel that this passage was extending downward in general, branching off after about twenty meters, and then many rooms appeared.

After entering one of the rooms, Xingxiaxiu had an eye-opening experience.

The shelves are filled with glass jars of various sizes, containing all kinds of strange things.

An eyeball, a body part, could be human, could be from another animal, the list goes on.

Of course, what Hoshita Shuichi saw the most were samples of various snakes, especially white snakes.

"Software transformation, the beginning of Yamata no Orochi?"

Hoshita Xiuichi secretly thought.

At this time Orochimaru came to a glass jar and said: "Now, this is what I want to show you."

Hoshixia Xiuyi stepped forward, his eyes fell on the things in the jar, and he was slightly startled: "Bull...horns?"

Orochimaru smiled mysteriously: "This is no ordinary horn!"

Hoshita Shuichi pretended to be ignorant: "Is it the horn of some kind of powerful psychic beast?"

"eight-tail!"

Orochimaru said: "You should have heard of it, the Eight-Tailed Jinchuuriki of Kumo Ninja, Killer Bee Kirabi."

Shuichi Hoshita showed surprise, then nodded: "Minato-sensei did once mention that the Eight-Tails is a terrifying monster with extremely amazing chakra, so it was sealed in the human body and used as a powerful weapon. "

This is indeed popular science once used by Namikaze Minato.

In this day and age, there are quite a few Tailed Beast Jinchūriki appearing on the battlefield.

Especially the two families, Kumo Ninja and Iwa Ninja.

In fact, the current Uzumaki Kushina has also lifted the restrictions on forbidden storage, and she occasionally performs tasks.

Of course, they are usually protected while performing tasks!

However, he did not go into too much detail about the Jinchūriki's popular science of Feng Shui.
