Analyzing the Ninja World Starting from Konoha

"ha?"

Jiraiya, who had been watching the show, paused, pointed at himself, and exclaimed in disbelief, "Me?"

Minato was also stunned, clearly not expecting Aoba to make this choice.

"Yes."

Aoba's eyes were firm. "Jiraiya-sama's defensive barrier formed by his hair is both offensive and defensive, flexible and versatile. I am amazed by his idea of ​​turning a part of his body into a weapon."

After a brief moment of surprise, Jiraiya suddenly burst into laughter.

"Hahaha! Good lad! You have good taste!"

He then rushed over suddenly, and his large, fan-like hand slammed heavily on Qingye's shoulder, the force of which almost made Qingye lose his balance.

"I knew it! This is a truly discerning ninja! Minato always complained that my Lion's Mane Technique wasn't cool enough, he just didn't know how to appreciate it! I never thought someone would finally recognize its value!"

He was like someone finally finding a buyer for a slow-moving product, his enthusiasm was irresistible.

Minato stood to the side, helplessly rubbing his forehead and smiling bitterly.

Indeed, he had no interest in this kind of technique that made hair longer and thicker, and always felt that the style was a bit strange.

However, he was also happy that his teacher's ninjutsu had found a successor.

"That's right! This is art! Using hair as a weapon allows for both surprise attacks and defense. Since you have such good taste, this immortal will make an exception and teach you!"

"Ninjutsu may look simple, but there's a lot more to it than meets the eye!"

Jiraiya was in high spirits, finding Aoba increasingly pleasing to the eye. "Listen carefully," he said, "this technique is a secret ninjutsu created by this sage. Its core principle is not simply chakra attachment, but rather using Yang-attribute chakra to stimulate hair follicle cells, causing them to undergo rapid division and hardening in an instant..."

Jiraiya plucked a white hair and held it up on his fingertip. "Although hair is made up of dead cells, the hair follicle is alive. By injecting Yang-attribute chakra into the hair follicle, I instantly stimulate cell division and growth, while simultaneously attaching the chakra to the hair shaft, hardening it like a steel needle."

"This is not just a change in form, but also involves the activation of bodily functions, which can be considered a special application of Yang Dun."

Over the next few hours, the third training ground was transformed into a hair salon training session.

Aoba listened intently, her eyes behind her sunglasses flashing with a faint blue light.

Although Jiraiya usually seems unreliable, he is surprisingly strict when teaching ninjutsu.

He explained the flow of chakra while slowing down his movements to demonstrate the hand seals.

"Si-wu-mao..."

Aoba stared intently, her eyes slightly narrowed behind her sunglasses.

Jiraiya's smile vanished, and his chakra surged instantly.

"Ninjutsu: Needle Jizo!"

His once smooth white hair instantly hardened, standing up like steel needles, enveloping Jiraiya and forming a spiky defensive sphere.

"This is for defense."

The kunai that Minato threw hit the surface, producing a series of metallic clanging sounds.

Immediately afterwards, his white hair came loose and grew wildly like a mad snake, instantly wrapping around a boulder in front of him. With a thought from Jiraiya, the hair tightened sharply, and the boulder shattered instantly.

"Ninja Art: Lion's Mane Technique! This is the attack."

Aoba stared intently, the data stream on his retina flashing wildly.

[Analyzing the surgical procedure model...]

[Yang Release Chakra Activation... Hair Follicle Stimulation... Cell Hardening...]

[Technique structure analysis in progress... Chakra flow simulation in progress...]

[Analysis complete, model established.]

"How about it? Do you understand?"

Jiraiya shook his head, his hair returned to normal, and he looked smug.

"I think... I understand."

Aoba closed his eyes and mentally simulated the flow of chakra using the chip.

"Alright, now you try it."

Jiraiya crossed his arms and stepped aside.

Aoba took a deep breath and formed a hand seal.

Si-chen-wei-shen.

"Ninja Art: Lion's Mane Technique!"

Chakra surged into the top of his head, and he could feel a tingling sensation on his scalp, as if countless ants were crawling on it.

Then--

The hair stood on end as if it had been electrocuted, which looked quite intimidating, but it had no power whatsoever.

"..."

Aoba's lips twitched.

Jiraiya burst into laughter, laughing so hard he almost fell over.

"Hahaha! Kid, it's normal to be like this the first time, don't be ashamed!"

Minato couldn't help but laugh, but quickly composed himself and said gently, "Aoba-kun, take your time, good luck!"

Qingye was not discouraged.

Actually, he did it on purpose; he didn't want to appear too much of a genius.

He closed his eyes, readjusted his chakra output, and formed hand seals again.

This time, the hair finally stood up properly, although it was still powerless, but at least it could move a few times.

"Not bad, not bad, you've improved."

Jiraiya nodded. "Continue."

For the next hour, Aoba tried repeatedly.

The chip is constantly adjusting its parameters, and every failure is recorded. The data from these failures is of great reference value.

Finally, after what seemed like the umpteenth failure, Aoba's palm trembled, and his hair suddenly grew back, piercing the tree trunk in front of him like a sharp blade.

puff--

Several strands of hair were deeply embedded in the tree bark. Although the power was far less than Jiraiya's demonstration, it already showed the prototype of actual combat.

"It's done!"

Jiraiya's eyes lit up. "Kid, you have good ninjutsu talent!"

Minato also showed an approving expression.

"Aoba-kun, your learning speed is truly amazing."

Despite Aoba's best efforts to slow down his learning pace, Minato was still impressed that he could learn a ninjutsu comparable to Rank A in just one hour.

Aoba grinned, shook his head, and felt his chakra being depleted.

Fortunately, it's within an acceptable range.

The three of them sat under the shade of a tree for a while, chatting about this and that.

Minato mentioned that the situation at the border has been somewhat tense recently, with frequent movements from Iwagakure and the village's Jonin preparing for missions.

Jiraiya complained that he had finally managed to get a few days off, only to be sent out by the old man again.

Aoba listened quietly, occasionally interjecting with a word or two.

He knew that the prelude to World War III was slowly beginning.

time is limited.

As he stepped out of the third training ground, he began to conceive his next plan.

Hair can be used as a medium for ninjutsu because it is part of the human body and has a high degree of adaptability to one's own chakra.

So, if you grind your hair into powder and mix it into sand, will it increase the sand's affinity for chakra?

If we go a step further, could we use blood, fingernails, or even cloned cell tissue to make sand a true "body extension"?

He needs to go back to do the experiment.

However, instead of going straight home, he went into a herbal medicine shop.

This is the Nara family's herbal medicine shop. The Nara family supplies almost half of the medicinal herbs in Konoha and has a deep connection with Konoha Hospital.

The owner was a middle-aged man wearing glasses. When he saw Aoba come in, he greeted her with a smile.

"Little Green Leaf, what do you want to buy today?"
