Analyzing the Ninja World Starting from Konoha

Aoba sat on his tatami mat, toying with the journal he had brought back from the hospital. Blue light flashed in his eyes; the chip system was performing simulations.

With the change in Aoba's identity, he could do more things, and no one would stop him from bringing general research materials home.

Various books and documents were piled up throughout the room, and crumpled manuscripts were scattered on the floor. After all, the basic appearance had to be maintained, so that if someone ever came to his house for a stroll, they could see that he was a good student who loved research.

In fact, there are quite a few of these incomplete techniques in the materials that Professor Ueno has made available.

Its uses are also diverse, but of course, it doesn't mean that all these techniques were developed by Ueno-sensei.

Many of these works were left by predecessors, but research on them has stalled or been abandoned for various reasons.

The data was also preserved to see if anyone could continue to improve it.

However, only a few can be perfected; most of them end up as yellowed documents.

I don't know how many times it's been handled, but the corners of the pages are all worn rough.

The reason why Aoba valued the Chakra Absorption Technique was because it was a very unique technique among many ninjutsu.

Because it has a heaven-defying characteristic: it can absorb chakra from the outside to replenish itself.

In this world, chakra is like mana, it's like battery life.

The original anime showed several characters capable of absorbing chakra, the most memorable being Samehada, the great sword of the Seven Ninja Swords of Kirigakure, which could absorb the opponent's chakra and inject the absorbed chakra into the user's body.

There's also the Rinnegan and the Dark Release, which rarely appears. Of course, absorbing chakra is only one of the functions of the Rinnegan.

By the way, it seems Madara could also do that. During the Fourth Shinobi World War, right after his resurrection, he extracted the Sage Chakra of Edo Tensei Hashirama even without his eyes.

Fighting with bloodsucking—who could resist that temptation?

Add another dragon slayer...

Uh, wait, I'm getting off-topic.

Whether it's Samehada or Rinnegan is out of the question right now.

The version for beggars is worth studying first.

The principle behind this technique is based on the framework of the "Small Ailment Extraction Technique," which involves direct contact to guide chakra out of the target's body.

"interesting."

Aoba's eyes behind his sunglasses gleamed slightly. Rather than relying on external forces or props, he wanted to grasp the essence of the technique, something that no one could take away from him.

According to his memories from his previous life, this technique was used on Sasuke by a Sound Ninja spy named Akabane Armor during the Chunin Exams.

It was performed in the form of ninjutsu, not through blood or special abilities.

This suggests that Orochimaru perfected this technique, or will perfect it in the future.

As for Orochimaru himself not using it, it's either because he doesn't think much of it, or because the technique doesn't meet his requirements for use.

Judging from the performance of the Copper Armor at the time, this technique was extremely inefficient, with an absurdly slow extraction speed, and it was easy to be countered by the opponent during absorption. It had too many drawbacks, no wonder Orochimaru didn't like it.

A typical example of something useless.

It may be a bit of a dud, but it has immense potential.

Aoba believes that any technique goes through a process of development from nothing to something, and from weak to strong.

If Orochimaru can do it, there's no reason why he can't. Even if he can't, there's always the chip system, which definitely can.

"Okay, system, get to work."

[Command confirmed... Model building in progress...]

Aoba poured all his computing power into the deduction of the new technique, and his chakra was slowly decreasing.

Aoba finally got up at noon the next day, dragging his tired body.

I've used up too much chakra, and I feel lethargic and lack energy.

This is why he values ​​this new technique so much.

I'm short on mana!

Fortunately, after a night of deduction, the system managed to complete the technique.

Yes, it was barely.

Aoba personally scanned all the data into the chip's database, so he knew exactly what was in it. He could complete the technique himself in a few days, and the chip simply accelerated that process.

Therefore, chips only play an auxiliary role and cannot create life out of thin air or give you knowledge that you don't have.

The entire procedure was still very rudimentary.

Let's simulate it again using a chip.

Safety.

"We need to find a guinea pig to try it out."

Aoba turned her head and found Yuhi Kurenai with a box of red bean dumplings in her hand.

"Hong, come here for a second, do me a favor."

"what?"

Hong glanced warily at the box in his hand and instinctively took a few steps back.

Damn, Aoba recalled everything related to Kurenai, but it seems he didn't do anything to Kurenai.

On several occasions before, Aoba had Hong try the new ingredients she had researched, and they were a bit spicy, causing her lips to turn red for several days.

"I won't fall for it again. Don't try to fool me."

"These are just your favorite red bean dumplings, really, nothing else was added."

To prove his credibility, Aoba opened the box and ate one.

"Really? You're so kind, what do you want?"

Hey~

As children grow up, they gradually learn to view the world with a dialectical perspective.

Aoba was relieved; at least she wouldn't be easily tricked away by the bad uncle with just a piece of candy.

"I've just developed a really fun ninjutsu technique, and I'd like to find someone to try it out on."

"Developing ninjutsu?"

Hong exclaimed in surprise.

"It's just a very simple ninjutsu, and there's no danger at all, so don't worry."

"real?"

Hong was somewhat skeptical, but she agreed out of trust in Qingye.

She also wanted to see what kind of ninjutsu Aoba had developed.

"How do I do it?"

"Relax, just stand normally."

Hong did as she was told, and Qingye approached and put her hand on Hong's shoulder.

The blue light in his eyes behind the sunglasses flickered slightly.

[Chakra Absorption Technique Version 1.0, activated.]

My palms felt slightly warm, and a very weak suction force was generated.

Hong's body stiffened abruptly. She felt a strange tingling sensation in her shoulder, as if her chakra was being pulled away by something. The feeling wasn't painful, but it was just a bit strange.

"Aoba, are you done?"

Hong turned her head, her face slightly flushed. "...Something feels off."

"Oh, that's normal. Relax and don't be nervous."

"It'll be ready soon..."

Aoba gently comforted her, her eyes fixed on the real-time data on her retina.

It's too slow, and the conversion rate is shockingly low.

The absorbed chakra is impure and requires one's own effort to purify and assimilate it. This back and forth might actually result in a losing proposition.

A few minutes later, Aoba withdrew his hand.

"How are you feeling?"

"Um……"

Hong stretched her shoulders, her face flushed. "I'm a little tired, like I just ran 10 laps around the track, and I also feel... a little hungry?"

That's for sure. With some of the chakra being drained, the body's energy will naturally be depleted.

"Looks like it's working well. You can have these red bean balls. They'll be ready in a bit."

Aoba placed the pastries in Hong's arms and turned to rush to the hospital.

red:???

No, they're leaving now.

Hong pouted angrily as she watched Qingye leave, vowing never to talk to him again.
