Just once!?
Hiroki had managed to control the chakra at the soles of his feet and attach himself to the wall—on the very first try? Was his chakra control really that precise?
Just one attempt? Seriously?
Nawaki stood there, completely baffled.
How is that even reasonable?
It's not reasonable at all! (╯‵□′)╯︵┻━┻
Aren't ninjas supposed to rely on passion, hard work, and endless struggle?So why was there suddenly a guy talking about data, formulas, and units—and actually succeeding in one try!?
This wasn't how a ninja story was supposed to go!
Isn't training meant to be full of repeated failures, desperate shouting, and dramatic breakthroughs alongside your rivals?How did Hiroki manage to succeed immediately?
If he were the protagonist of a novel, there wouldn't even be any conflict!
Across the field, Uzumaki Kushina's eyes widened in disbelief.
Hiroki… how did he do that?
Her mind echoed with his earlier question—Can chakra actually be calculated?She looked down at her own feet. Could she also control her chakra as precisely as he did, if she followed the same idea?
It wasn't just the two students who were stunned. Their teacher, Orochimaru, was equally shaken. His golden eyes narrowed, fixed intently on Hiroki's ankles.
It worked.Not only did it work—it worked instantly.
But this wasn't just blind luck or raw talent.It was something deeper.
Hiroki had proven his theory.
Chakra could be quantified. The experiences and instincts of other ninja could be translated into measurable, repeatable data. Chakra didn't have to rely on guesswork or intuition—it could be analyzed, defined, and understood through precise calculation.
And in that moment, Orochimaru saw it clearly—this was a methodological revolution.
His thoughts raced.
If this method could be taught and replicated, ninjutsu training would be transformed.Talent would no longer depend on vague "chakra control sense" but could be objectively measured.Ninjutsu development would move from endless trial and error to precise, theory-based refinement.
For example, instead of just "imagining" chakra flow during the Transformation or Substitution Techniques, lessons could define:
The exact form to visualize,
The number of standard chakra units to channel,
The proper amount to sustain the technique.
Exams could measure performance in standardized chakra units:"How many units did you use for the Transformation Technique?""What form did you produce?""What efficiency did you achieve?"
A new era of ninjutsu was dawning.
Orochimaru couldn't help but lick the corner of his mouth.
Even the Anbu and Root operatives watching from the shadows were stunned into silence.
They were veterans, their mastery of chakra honed into instinct over decades. Chakra control was second nature to them—something felt, not calculated.
But precisely because of that, they understood the true impact of what they had just seen.
Hiroki's success in tree climbing wasn't impressive simply because he did it in one try. Elite Anbu could do that too.What made it shocking was how he did it—through precise calculation.
He hadn't relied on feel or experience; he'd measured, analyzed, and quantified his chakra output—and it had worked.
That meant something terrifying:
They had spent their entire lives perfecting chakra intuition…and maybe, just maybe, it had all been a colossal waste of time.
Today, a child had shown them that chakra—the foundation of their power—could be reduced to numbers and equations.
Maybe they had all been missing just one thing:a standard unit of chakra.
If someone had told them exactly how much chakra to extract and how much to release, could they have mastered techniques in a single day?
Could they have saved years of trial and error?
A quiet unease spread among the hidden observers.Some even felt a faint resentment—though they didn't know whether it was directed at Hiroki, at Orochimaru, or at themselves.
Maybe they had once had a chance to do the same.
In the heavy silence, Hiroki moved.He lifted his other foot, channeled chakra with perfect precision, and took another step up the wall.
His movements were clumsy, but each step was steady and controlled.
Up in a nearby tree, a cat startled by the commotion arched its back and hissed at Hiroki before leaping away—springing across a small stream.
Orochimaru's gaze followed it, and without hesitation, he leapt after—running straight across the surface of the water.
Running on water!?
Yes—water walking, the advanced form of chakra control beyond tree climbing.
While Nawaki and Kushina stood frozen, Hiroki had already reached the stream. He was still calculating, still thinking about chakra output, when Orochimaru's calm voice broke the silence:
"Two-sixths of the Transformation Technique," Orochimaru said. "Twice the amount used for tree climbing."
His meaning was clear.He wanted to see if Hiroki could replicate his success again.
Nawaki and Kushina turned their eyes to Hiroki, holding their breath.
Could he do it again?
Hiroki took a deep breath, updated the code in his mind, and began refining chakra—this time outputting energy at 24 units per second, twice his previous rate.
Then he stepped forward.
His foot struck the water. There was resistance—uneven, unstable—but still there.
Not enough. Increase output.
25 units per second.
The surface steadied beneath him.
A little more—26 units per second!
Now he stood firm.
Then Hiroki took another step, faster, lighter, until he was running across the surface as if it were solid ground.
He had done it again.
He had succeeded.
