Naruto: I, a decent person, have become the mastermind behind all this!

After Danzo left, Orochimaru looked at Shuichi Hoshita and smiled meaningfully: "Shuichi-kun, you really didn't disappoint us."

"However, being a double agent is not easy."

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

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

Shuichi Hoshita turned his head 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."

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

He has put Shuichi Hoshita in a relatively equal position, without any condescension.

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

Turning to walk out, Orochimaru continued: "Is it Shuichi-kun's ideal to master all types of ninjutsu?"

Hoshita Shuichi followed a 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 an endless stream. If you want to learn them all, I'm afraid you won't be able to do it in your lifetime."

Orochimaru felt the same way: "Indeed."

But he immediately changed the subject and said temptingly: "But Shuichi-kun's knowledge is still too little. There are many beings with extremely long lifespans in this world?"

Hoshita Shuichi pretended to be ignorant: "Lord Orochimaru, are you talking about those who have People with special physiques?"

"I've heard that the Uzumaki clan has a very long lifespan."

Orochimaru turned his head and looked at Hoshita Hideichi, and smiled: "No, even the Uzumaki clan is just a mortal."

Hoshita Hideichi nodded and thought: "Indeed."

"As long as you are human, you can't get rid of the limit of the number of cell divisions."

"That's why in medical ninjutsu, the technique of rapid cell division comes at the cost of life."

"I have also studied many other animals, and flesh and blood can't get rid of this shackles."

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

Like Tsunade using chakra to keep herself in her thirties, this is not just for a beautiful face.

More importantly, it is actually using chakra to keep cells active, or to slow down the speed of cell aging, prolong the cycle of cell renewal, so that cells can reduce the number of divisions, so as to achieve the purpose of prolonging life.

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

Even 500 years is not enough.

Because chakra comes from the body and spirit, the aging of organs is irreversible, the consumption is small, but it always exists.

"Senjutsu..."

Hiroshita Shuichi's thoughts diverged, thinking of the Sage Mode, and then the state of Kabuto Yakushi.

Then he thought of Jūgo.

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

"In the ninja world, the only direction for longevity seems to be the sacred tree and senjutsu..."

To be honest, this is the first time that Shuichi Hoshita has thought about the issue of longevity.

He is really too young.

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

Orochimaru swept his eyes across Shuichi Hoshita's pensive face and saw the light flashing 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 a gain, just a small idea that can slow down cell aging and prolong the cell division cycle." Orochimaru was very interested: "Oh?" "Can I know?" "Of course, I will repay with something of equal value." This was exactly what Shuichi Hoshita wanted, and he immediately smiled and said: "Of course there is no problem with this, it's not something extraordinary or confidential." After that, Shuichi Hoshita told him the 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, maybe some of them were useful? And this was indeed the case. There were still many things worth learning from Shuichi Hoshita's ideas. After listening, Orochimaru smiled and said: "It is indeed a very interesting idea, very groundbreaking." "Shuichi-kun really deserves to be praised by Tsunade and Jiraiya as a genius." Shuichi Hoshita was a little embarrassed by the praise. However, he had practiced to be very thick-skinned, and did not blush. Just as he was about to speak, Orochimaru stopped and said, "We are here!"

Hideichi Hoshita looked ahead and saw an entrance.

Is he being brought to the experimental base?

Hideichi Hoshita looked around and said, "Lord Orochimaru, is this the secret base of the Root?"

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

He then led Hideichi Hoshita through the entrance into a long corridor.

Hideichi Hoshita could feel that the corridor was generally extending downwards, and after about twenty meters, it branched out, and then many rooms appeared.

After entering one of the rooms, Hideichi Hoshita was amazed.

Shelves were filled with glass jars of various sizes, which contained 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 said.

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 the popular science popularized 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 restriction on leaving the village, and she occasionally performs missions.

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.

Perhaps Minato Namikaze doesn't know as much about Jinchuuriki or tailed beasts as Shuichi Hoshita!

Orochimaru smiled and said, "What Minato said is indeed correct."

"Behaviors like tailed beasts not only have amazing chakra, they also have unparalleled lifespans."

"It is said that they have been alive from the time of the Six Paths Sage until now, and every time a jinchuriki dies, they can be resurrected."

Hoshita Xiuichi looked appropriately shocked, staring at the small horn in the glass jar: "The legendary era of the Six Paths Sage is very far away, isn't it?"

"Can you really live to this day and be resurrected continuously?"

"Lord Orochimaru, how did you get this."

"Minato-sensei said that tailed beasts have the power to destroy cities."

Orochimaru smiled with a bit of pride: "Jinchūriki, or tailed beasts, are indeed very difficult to deal with, but there are still ways to get some cells from them."

Hoshita Shuichi was surprised: "Did you, Orochimaru-sama, cultivate this with Eight-Tails cells?"

"What an amazing skill. I'm afraid Tsunade-sama can't compare to you in this regard."

Orochimaru nodded: "We are not going in the same direction."

"Unfortunately, the tailed beast's power is too violent and is currently not suitable for transplantation into the human body."

At this point, he was indeed very sorry.

But having said that, he still plans to continue to cultivate this Eight-Tailed Horn.

Although the power of the tailed beast is too violent, it also has many wonderful uses.

With this thing, many experiments that were difficult to carry out before can be carried out.

Turning to look at Hoshita Shuichi, Orochimaru smiled and said: "Shuichi-kun, you have amazing ideas and are very suitable for research. How about it? Are you interested in studying how to make people's bodies immortal with me?"

“I believe this will be a very great cause.”

"With the development of such technology, some injuries that could not be solved before will no longer be a problem."

Orochimaru's voice was full of temptation, and it contained a hidden message for Hoshita Shuichi.

Hoshita Shuichi withdrew his gaze from the Eight-Tails Horn and said with a wry smile: "Lord Orochimaru, of course I am willing to do this."

"But you also know that I have become a double agent now, and the situation here may be inevitable..."

Orochimaru smiled softly and said: "You can just report the situation here to the Third Generation. There is nothing that cannot be said."

After hearing this, Hoshita Shuichi immediately bowed and said: "Then, I will ask Orochimaru-sama for your advice from now on!"

Orochimaru nodded with a smile, and then turned around: "Come and take a look at my research. This can be regarded as my reward for you!"

…

It was already dark when he came out of Orochimaru's experimental base. As he walked towards the Hokage Building, Hoshita Shuichi was also thinking secretly: "Is it really because of my talent that Orochimaru recruited me to do experiments?"

"Or for Kyuubi?"

The Nine-Tails Jinchuuriki is a secret among many Konoha ninjas, but Orochimaru is definitely not one of them.

"This little scheme shouldn't escape the eyes of the third generation, right?"

Hoshita Shuichi secretly thought: "It seems that Orochimaru is up to something."

"This is going to be subtle, letting me sink deeper and deeper into this research path, and then..."

"It's really thoughtful."

"But there are indeed many things from Orochimaru that I can learn. In terms of research on the human body, cells, and cloning, Tsunade is absolutely unmatched."

Thinking about it, Hoshixia Shuichi focused on the entries in his mind.

A new entry has been triggered!
