Analyzing the Ninja World Starting from Konoha

【Sand Control Secret Technique 2.0】

If he so chooses, he too can, like Gaara, extract sand and gravel from the ground and assimilate it for his own use.

No more worrying about not having enough sand.

The three-day break flew by.

Without any new mission notifications, Aoba returned directly to Konoha Hospital to continue working as a salted fish doctor.

To be honest, he actually missed the feeling of doing missions outside the village.

No!

The ninja world is dangerous, and such dangerous thoughts must be nipped in the bud.

Qingye quickly reminded herself not to get carried away.

Stepping into the gates of Konoha Hospital once again, the familiar smell of disinfectant hit me.

"Hey, isn't this our genius ninja, Yamashiro Aoba? Finally decided to come back to work?"

Even from a distance, Qingye could feel a strong sense of resentment from the cattle and horses coming towards him.

Yumiko was lying on the table, with huge dark circles under her eyes, staring intently at him.

That resentment could feed two evil sword immortals.

"Ahem, good morning, Yumiko-neechan."

Aoba greeted everyone without a care in the world, completely ignoring Yumiko's situation.

It's obvious to anyone that during his absence, Yumiko must have been thoroughly exploited by Ueno-sensei.

"You're finally back. I felt like if you hadn't come back soon, the next time I'd have to visit you at my grave."

"It's not that exaggerated. Professor Ueno wouldn't want you to die."

Qingye said with a smile.

"Come here, I've got something good for you."

As if by magic, he pulled out a delicate little box from behind his back and handed it over.

"What is this?"

Yumiko took the box with suspicion.

"These are local specialties I brought for my beautiful sister Yumiko. Shall we open them and take a look?"

Yumiko opened the box with some skepticism.

The next second, her eyes instantly turned into stars.

"Wow!"

Inside the box lay a palm-sized, chibi-style nine-tailed puppet.

She fiddled with it for a bit and discovered that the little thing's joints could actually move, and its nine tails could even be posed in different ways.

"So cute!"

This little figurine was a practice piece that Aoba made yesterday to practice her puppetry skills.

With its bright orange paint job, nine tails covered in fluffy hair, and those deliberately enlarged, watery eyes, it's incredibly irresistible to young girls.

"Alright, I'll forgive you this time."

Yumiko played with the little nine-tailed fox with obvious affection, and the resentment on her face instantly dissipated by more than half. "Go report to Dr. Ueno. She's been talking about you for ages."

Having dealt with Yumiko, Aoba went straight to Dr. Ueno's office.

Pushing open the door, I found Professor Ueno buried in a pile of documents.

Hearing the door open, Ueno looked up and saw Aoba, a gentle smile immediately appearing on his face.

"You're back."

"Teacher, I'm back."

Aoba bowed respectfully.

Ueno put down his pen, looked Aoba up and down, and only after confirming that he was not missing any limbs did a gentle smile appear on his face.

"It's good that you're back."

Ueno gestured to the chair next to him. "Sit down. How was the mission? Are you settling in well?"

"It feels alright. Minato-senpai is leading the team and he's been taking good care of me."

"Minato, looks like this mission is going to be pretty tricky."

"Yes, we encountered some unexpected situations."

Aoba sat down and said casually, "But with Minato-senpai there, everything was resolved without any real danger."

"Yes, it's good that you're back safe and sound."

"Why didn't you rest for a few more days?"

"I'm fine, teacher. I've had three days of rest."

That heartfelt concern warmed Aoba's heart.

With Ueno's help, Aoba reintegrated into the daily work at Konoha Hospital.

For the next few days, Aoba lived like a true medical ninja, going back and forth between the operating room and the archives every day.

No further tasks were assigned to him at the Hokage Building.

This made Aoba feel that something was wrong.

Based on his performance in the Loulan mission, that old bastard, the Third Hokage Hiruzen Sarutobi, would definitely not let such a "high-end combatant" stay cooped up in the hospital as a wet nurse.

I have a feeling... this old guy isn't up to anything good.

However, this rare period of peace is a good opportunity for him to properly digest what he has gained this time.

He re-examined the technology for modifying human puppets.

Aoba sat at his desk, toying with a gray puppet fragment in his hand.

With a flash of blue light in his eyes, Centipede's data was finally organized. It not only contained the complete [Human Puppet Technique], but also Centipede's experimental data.

By reviewing the experimental logs left by Centipede, Aoba finally understood why that idiot wanted to modify him.

Originally, Centipede had only undergone partial modification in order to better control the puppet.

Unexpectedly, as he continued to use the Dragon Vein's chakra, his body began to risk petrification.

He gave up using the Dragon Vein Chakra, yet he couldn't bear to part with that almost limitless energy.

There was no other way but to undergo a more thorough transformation of himself in order to eliminate the influence of the dragon vein chakra on him.

Aoba immediately understood.

This also explains why, despite being a Jonin of Sunagakure, Centipede couldn't possibly be unaware of the dangers of complete modification, he still did it without hesitation.

That's sunk cost.

Once you invest too much, it's hard to extricate yourself.

This is human nature!

"What a pathetic guy."

Aoba shook his head and threw the petrified fragment in his hand back onto the table.

Power, if not fully controlled, will eventually backfire on you.

The technology for human puppets is temporarily shelved.

With the completion of the human puppet and the sand control technique, the computing power that had been occupied by the chip was finally released.

Without the slightest hesitation, Qingye immediately devoted all available computing power to the unknown data packet from the dragon vein.

Like opening a "blind box," Aoba was secretly looking forward to it.

Three nights later.

With a "ding" in her mind, Aoba was suddenly awakened from her deep sleep.

The data parsed from the data packets is projected onto the retina.

"This is... ninjutsu?"

[Forbidden Technique: Impure World Reincarnation]!!!

Even Aoba couldn't help but feel her heart race at this moment.

It's actually this bug-level forbidden technique that's been present throughout almost the entire Naruto series!

The S-rank forbidden technique developed by the Second Hokage, Tobirama Senju, can summon the souls of long-dead ninjas back to the world of the living and revive them in physical form.

Later, Orochimaru perfected it, and finally, Kabuto Yakushi brought it to its full potential, even making it a super-powerful force to be reckoned with during the Fourth Shinobi World War.

With the DNA of the deceased and a human sacrifice, the dead can be summoned back from the Pure Land, possessing unlimited chakra and immortality.

He had imagined countless possibilities, but he never thought that the data packets emerging from the dragon vein would contain such a thing.

This is practically begging for food while holding a golden bowl!

In Aoba's view, the most powerful aspect of this technique is not its combat capabilities, but rather the knowledge it can provide.

Every departed strongman is a walking treasure trove of knowledge.

Their combat experience and secret techniques are invaluable assets to the ninja world, and it is a great loss to take them to the grave.
