Analyzing the Ninja World Starting from Konoha

Having formally come into contact with the ninjutsu knowledge of chakra form transformation and nature transformation, Aoba could finally conduct his research and training openly.

No more secretly practicing Fire Release and Earth Release, though of course, practice must be done in private or in a secluded place.

He didn't want to stand out too much. In Konoha, a village teeming with geniuses and rife with undercurrents, excessive talent was sometimes not a good thing; it might even attract unwanted attention.

Especially since he's a kid with a lot of medical talent, he doesn't want to be targeted by "Root" or Orochimaru.

With more systematic and comprehensive knowledge, Aoba made a qualitative leap in his training in chakra form and nature transformation.

He originally thought that the first thing he would master would be the more aggressive Fire Release nature transformation, since there was a complete Fire Release ninjutsu as a reference.

However, unexpectedly, the Earth Release technique opened the door for him first.

Aoba leaned against a large rock, playing with a grayish-white pebble in her hand.

The stone had a smooth surface. He had picked it up casually a week ago and would often hold it in his hand and play with it, occasionally channeling chakra into it to sense the 'weightiness of earth' within.

Unexpectedly, after Aoba continuously injected chakra, the pebble underwent a special change.

He could clearly sense that this ordinary pebble, because it had been "infiltrated" by his chakra for a long time, had developed a peculiar "activity" and was no longer so repulsive to his chakra.

It was then scanned.

Material: Sedimentary rock. Density: 2.6 g/cm³.

[Chakra erosion level detection in progress...]

[Current erosion level: 10.2%. Nature determined: Chakra erosion.]

"The 'contamination' of chakra...?"

While it may be described as erosion, Aoba is more likely to be a form of pollution.

Knowing the plot, he clearly understood that chakra was a completely foreign concept.

Alien products.

The Sage of Six Paths founded the Ninjutsu sect, which spread chakra, and it has now spread throughout the entire ninja world.

Not only humans possess chakra, but animals and plants also have it, and there has even been something called chakra metal.

Of course, once you're in the thick of it, it's no longer important to worry about where the chakra comes from.

Aoba is now interested in this corrosive 'pollution'.

After conducting research, Aoba came to a conclusion.

This is not pollution in the traditional sense, but more like assimilation.

Chakra is like a dye with a strong personal imprint. When it permeates an object for a long time and continuously, the object's original properties are covered up, and it gradually takes on the user's color.

Qingye stroked the surface of the stone thoughtfully.

He wondered what would happen if he dyed all the stones his own color.

However, the stone's internal structure was too dense, making it difficult for chakra to penetrate.

If we compare chakra to water, then stone is like a dense, dry sponge. Water can only stay on the surface, and it takes a long time to soak the sponge to expand it.

If that's the case, let's try a different approach.

What if it's loose sand?

Aoba suddenly unleashed chakra from his wrist, instantly crushing the pebble in his palm into sand powder.

With a thought, Aoba opened his palm and some tiny grains of sand were drawn by an invisible hand; these were grains of sand that had been completely eroded by his chakra.

They didn't fly around randomly, but rather, with the flow of chakra, they gathered into an irregular little ball of sand about five centimeters above Aoba's palm.

Although it is only the size of a little finger and looks precarious, it is indeed a sand control device.

The Sand Village's [Sand Control Secret Technique]!

Magnet Release is Magnet Release, which uses magnetic force to control iron sand. The one Aoba is using now is simply to dye the sand his own color with chakra, and then add a little Earth Release nature transformation to make the sand float.

Strictly speaking, it can't be considered sand control; it's just controlling one's own chakra while incidentally controlling the sand.

Chakra alone cannot leave the body unless it is in the form of ninjutsu, but sand stained with color can leave the body, albeit only in small amounts.

However, Aoba provided an idea.

Furthermore, it is speculated that the so-called "Sand Manipulation Technique" of Sunagakure should have evolved from this.

This can be considered the earliest prototype of the Sand Village's "Sand Control Technique".

Aoba was very happy.

Discovering and utilizing the patterns in things made him feel as if he had rediscovered the feeling of being a scientific researcher in his previous life.

"Unexpectedly, researching the nature and changes of Earth Escape Technique yielded unexpected results."

"However, this initial version is still too rudimentary; it's entirely based on brute force with a large amount of chakra."

In just a short while, a fine layer of sweat appeared on Aoba's forehead, indicating that he had consumed a lot of chakra.

It seems that developing a practical "Sand Control Technique" is still a long and arduous task.

……

Ninja School, Experimental Class

The missing Tsunade has finally reappeared.

Despite having 'rested' for so long, Tsunade looked even more exhausted, with a deeper gloom between her brows, and she looked like she was still hungover.

Aoba glanced at Shizune and noticed that she was secretly covering her eyes.

Well, it seems that Jingyin did her best, having to take care of a baby who is over 300 months old at such a young age.

The previously somber experimental class was instantly ignited; the students' eyes shone with a light that seemed to radiate more affection than if they were seeing their own mother, and some even nearly burst into tears of joy.

The reason is simple: Professor Ueno's classes are just too "hardcore".

During this period, I was surrounded by either slippery frogs or disgusting rats every day, and the air seemed to be filled with a bloody and sour smell (from vomiting).

For a group of kids who haven't even graduated yet, it's a double torture, both mentally and physically; it's hell.

"Great, at least we don't have to do dissections anymore!"

"My hands are still shaking..."

"I used to dream that a giant frog was chasing me with a scalpel, sob sob..."

The classroom was filled with a joyful atmosphere of rebirth.

Naive.

too naive.

Looking at the excited cheers around him, Aoba remained much calmer, knowing all too well how wicked Tsunade's personality was.

As Aoba had predicted, Tsunade walked straight to the podium and glanced around with a smile.

"Great, everyone seems to be in high spirits, so..."

Tsunade slammed a stack of exam papers onto the podium. "Let's take the exam."

The once cheerful and lively classroom instantly fell silent, and smiles froze on people's faces.

It seems like I'm hallucinating.

assessment?

Now?

The classroom was deathly silent.

The students, who were still basking in the joy of their idols' comeback a moment ago, suddenly broke down in tears.

How can someone with a 37-degree mouth utter such cold words?

"What? Is there a problem?"

Tsunade raised an eyebrow, and an invisible sense of oppression instantly enveloped the entire room. "Do you think wounded soldiers on the battlefield give you time to prepare? Take everything away, and cheaters, get out of the experimental class immediately."

The wailing was forced back down his throat.

The test papers were handed out quickly.

Aoba received the exam paper and quickly glanced through the questions.

The difficulty level of the questions was also acceptable.

It covers basic theory, pharmacological knowledge, and chakra nature analysis, all of which Tsunade mentioned in her previous classes. Even without using an auxiliary chip to cheat, Aoba could easily handle these questions.

But he didn't rush to put pen to paper.

He was pondering a very serious question—what score would be appropriate?
