Naruto: The Uchiha's Scientific Madman

When Orochimaru unrolled the scroll, Ao silently activated his Sharingan and memorized all the contents of the scroll.

He immediately understood the purpose of the kunai left behind by Tobirama Senju.

At the same time, he also understood the final experimental content of Tobirama Senju's research, which was the manuscript of the forbidden Impure World Reincarnation technique in Orochimaru's possession.

Judging from the manuscript, this technique was not yet perfect.

Judging from the kunai and Orochimaru's attitude, Tobirama Senju has probably already completed this technique.

However, he did not use it during the Fourth Shinobi World War, which caused Orochimaru to lose his composure.

Ao noticed that the scroll contained extensive research on the soul, annotated by Tobirama Senju.

The most crucial point—the Soul Recall Technique—is based on the forbidden technique of the Uzumaki clan: the Corpse Demon Sealing Technique!

The research genius Tobirama Senju actually gained inspiration from the contract signed between the Uzumaki clan and the Shinigami, and created a soul technique that connects to the Pure Land and guides souls.

This is only the most basic of the basic techniques of the Impure World Reincarnation.

Even more amazing is that he created a technique to control the souls of those resurrected through the Impure World Reincarnation, enabling him to manipulate the dead to fight for him...

However, why did Tobirama Senju abandon a technique that was already perfected?

Qing felt confused.

It's speculated that Tobirama Senju probably discovered something even more hidden, forcing him to abandon this research...

Did he summon his older brother Hashirama Senju and get beaten up?

That's why I gave up perfecting the Impure World Reincarnation technique.

Qing couldn't help but think of this scene, and then the corners of her mouth involuntarily curved into a smile.

Hashirama Senju, who had been dead for a long time, suddenly came back to life and saw that his younger brother's research had gone astray. He touched his brother with love and then released the Impure World Reincarnation and returned to the Pure Land...

Perhaps only in this way would Tobirama Senju abandon his research into the forbidden technique of Impure World Reincarnation.

In the imperfect Reanimation Jutsu, Qing discovered a section describing the soul level, which mentioned the term "Pure Land."

This is the first time that evidence has been provided to prove the existence of "Pure Land".

Tobirama Senju was incredibly intelligent!

It is very likely that he had already sensed the Pure Land while he was alive, or even that he had been there once.

Qingdu might believe it.

Otherwise, how could Tobirama Senju have found a way to summon the souls of the dead back from the Pure Land, thus creating the Impure World Reincarnation?

At this moment, after reviewing all the information on the Impure World Reincarnation, Ao's mind filled in the biggest question about the Uzumaki clan's contract: why did the original Shinigami sign such an almost equal contract with the Uzumaki clan?

This contract not only has no binding force whatsoever, but it's also like working for the Uzumaki clan for free, with each payment being just one person's soul.

For example, there is no comparison between Minato Namikaze's soul and the Nine-Tails' soul.

Death, without hesitation, still chose to strike.

He's much easier to talk to than Manda, who is ostensibly the leader of Ryuchi Cave Hidden Village.

Manda needs one hundred blood sacrifices before it will work for Orochimaru.

Judging from his appearance, that guy didn't seem like a kind person at all.

"The Grim Reaper might not have been strong at the beginning..."

"Because of this contract, the Grim Reaper was slowly cultivated by the Uzumaki clan."

"The Uzumaki clan worshipped the Death God who had sealed away the corpse demon as their guardian deity... allowing it to slowly grow into a god at the soul level, which may even threaten the old man of the Six Paths' position in the Pure Land."

"No wonder they were the first to be wiped out; the Uzumaki clan's research was far too advanced."

"I wonder if that stingy old man Rokudo got involved."

Qing vaguely felt that he had guessed part of the truth behind the annihilation of the Uzumaki clan.

It is very likely related to the Shinigami who sealed away the corpse demon.

It's highly unusual that Konoha's best ally allowed the Uzumaki clan to perish without any response.

It's worth noting that when the Uzumaki clan was wiped out, the First Hokage's wife, Mito Uzumaki, was still alive.

Tobirama Senju also knew the Flying Thunder God Technique, so with the strength of Konoha at the time, saving the Uzumaki clan would not have been difficult.

Unless there was some reason that forced Tobirama Senju to sit idly by, and even with Mito Uzumaki's tacit approval.

"Let's go! It's getting late, Danzo might have realized what's happening..."

Orochimaru casually hid the kunai in his sleeve and said without making a sound.

He showed absolutely no presumptuousness in taking the spoils of war from his disciples, behaving quite normally, as calmly as if he were drinking water.

"Yes, teacher!"

Ao answered with his head down, quickly gathered up several items from the laboratory shelf, and left behind Orochimaru.

He didn't say anything more.

The two walked out of the laboratory one after the other. After returning to the hall, Orochimaru canceled the summoning jutsu, and Orochimaru returned to Ryuchi Cave.

"Let's go, see you in Ryuchi Cave!"

Orochimaru formed a hand seal, turned to Uchiha Ao, and said that he was very satisfied with his performance.

He doesn't ask many questions, is meticulous in his work, and has his own ideas.

It increasingly suited his taste.

Ao nodded, vaguely sensing Mizuki's call.

After he acquiesced.

A mysterious power emanated from the void, and he used all his mental strength to carefully perceive the source of this power.

Suddenly, I felt a dizzying sensation as the world spun around me.

A peculiar power enveloped him, and his body involuntarily began to decompose in an extraordinary way.

No… what is it…?

Before Qing could even process what was happening, everything suddenly went black, and she lost consciousness.

The next moment, when he regained consciousness, he was already in the open space in front of the White Snake Immortal Temple.

Mizuki was looking at him with a worried expression.

Reverse psychic abilities—

interesting.

Qing's eyes brightened.

Silently savoring the feeling from just now.

Keep it firmly in your heart.

This may be the secret of space-time ninjutsu.

"Lord Orochimaru is waiting for you at his residence."

Princess Mizutsu replied respectfully.

After Ao received the White Snake Sage's inheritance, his status in Ryuchi Cave rose significantly, and he is now the third most important person after the White Snake Sage and Orochimaru.

The three goddesses all became much more respectful to him.

"I see."

Qing replied.

He knew Orochimaru's address and left behind a complete set of research equipment in a cave in Ryuchi-dong.

It was probably prepared a long time ago.

However, there were no signs of use.

Everything was new.

When he arrived at the cave entrance, he saw Manda, who was coiled up in front of Orochimaru's house, fast asleep with his eyes closed, like a guard dog.

"Who?"

Manda noticed the gaze, suddenly raised its head, opened its pale yellow vertical pupils, and looked at Uchiha Ao, its pupils shifting.

The aura of immortals…

Are they Orochimaru's people?

I can't let this little guy get on my head.

"You're the disciple Orochimaru took in? You don't seem particularly imposing... Hmm!"

Just as Manda was about to swagger and suppress Uchiha Ao, he suddenly sensed something was wrong, and then a sharp, needle-like pain shot through his head.

When Manda looked up again, he found that Uchiha Ao had already left.

The image of the other person's scarlet three-tomoe Sharingan still lingered in his mind.

The Uchiha monster... what a disgusting genjutsu!

Inside Orochimaru's residence.

When Qing pushed open the door, he saw Orochimaru sitting in a chair, engrossed in reading a scroll.

"You're back. Your strength has improved quite a bit; you've even mastered Wood Release..."

"I have a task for you. I originally planned to go by myself, but this time I gained a lot, and you've grown a lot too, so I'll leave it to you!"

"There's been some trouble in Kirigakure lately. Could you go there for me and bring back a few promising bloodline limit candidates?"

"This mission is somewhat risky. Would you be willing to go for me, Qingjun?"

Orochimaru noticed the newcomer, looked up, put down the information about the Impure World Reincarnation in his hand, and spoke.

It appears to be a request, but in reality, it brooks no refusal.

Uchiha Ao nodded without hesitation after hearing this.

He's currently an assistant researcher; he does whatever his boss tells him to do.

I've long been used to this kind of life.

"Alright, I'll give you the details of this mission later. For now, go find a summoning beast partner. There are many good ones on Manda's side, so choose carefully."

Orochimaru rambled on for a while, but his eyes never left the scroll in his hand.

Having just returned, he immediately began a new round of research on forbidden techniques.

Even the most hardworking person isn't as dedicated as Orochimaru.

After he finished speaking, he ignored Uchiha Ao and became completely absorbed in the information about the Impure World Reincarnation.

This forbidden technique provided him with a great deal of inspiration for his research into immortality. He had many ideas in his mind that he wanted to implement, and he no longer cared about training his apprentices.

He completely forgot his original plan to take Uchiha Ao to Kirigakure for training.
