Naruto : Perfect Control Chapter 9- Looping Progress

Turns out, enhancing your brain with chakra... kind of works.

No, scratch that—it absolutely works.

I’d only managed to hold the enhancent for around two hours on the first try with my asly reserves before running out of chakra and that had drained almost everything for it. It left light-headed and sleepy by the end.

But those two hours?

Photographic mory. Logical clarity. Insane comprehension. It was like soone cranked up the brightness and contrast in my head. Everything made sense. Everything clicked.

I rembered dical scrolls I skimd months ago. I re-ran conversations in perfect clarity, noticing things I didn’t before. Patterns. Implications. Subtext.

Honestly... it was a little scary.

But also, amazing.

Even if the chakra didn’t last, the knowledge did. It was sothing like, if I mugged up sothing while in smart mode, the dumb would still rember it.

Or, if the smart mode found the solution of a problem, the dumb mode would still know the solution, you get the drill, right?

But that was the catch. It wasn’t permanent intelligence—just a temporary powerup. Like popping a buff and going full high-IQ mode until the chakra ran out. After that, I was back to the good old Inaba Shinkurou.

Well, maybe slightly above average now.

So, I started planning around it.

If two hours of brain-enhancent could give that much... what if I used it to study better? Refine the technique better? Think of a version that lasted longer?

So that’s what I did.

I woke up the next day, skipped classes for today, and sat cross-legged in the exact sa spot under the tree in my courtyard.

Chakra. Focus. Brain.

Boom. Smart mode, activated.

Then I opened the scrolls again—specifically, the ones on neurology.

And this ti?

It stuck.

I didn’t just read it anymore, I morized and understood every little thing about it.

One month.

That’s all it took.

In just four weeks, I covered the entire brain departnt of the Senju dical library. Everything they had—written by centuries or millennia of dical specialists, refined by war dics, polished by contributors like Tobirama Senju himself—I read it all.

No, I morized it all.

I understood it all.

And then went further.

There were inconsistencies. Gaps. Things nobody had dared to explore because they lacked chakra control fine enough to test their theories without causing brain damage.

But ?

My chakra control was a scalpel. No—more precise than a scalpel. It was the one thing where I was at God tier level.

I started making notes. Corrections. Modifications. Theories.

Layer by layer, I built an entirely new model of how chakra interacted with brain tissue, cognition, synaptic transmission, cerebral chakra flow patterns...

By the end of the month, I wasn’t just learning neurology.

I was advancing it.

If anyone ever did a deep dive on brain-based chakra manipulation in the future, they’d probably stumble upon a few footnotes with my na on them.

And the best part?

It was all just the start, all of this was just the prelude to my real goal.

See, the first brain enhancent was just... raw. Crude. I didn’t know what I was doing, so I brute-forced it with my half-baked neurology knowledge along with chakra control and good intentions.

But now?

Now I knew the structure of the brain. Every section, every flow zone, every point where chakra could stimulate mory formation, attention span, neural acceleration, and creative logic.

I rebuilt the entire enhancent pattern from scratch.

The new version?

Sharper.

Cleaner.

More efficient.

It only needed 60% of the chakra of the previous one... and lasted nearly three hours.

That was the first improvent.

After using that version, I realized how flawed even this model was.

So I rebuilt it again.

Then again.

And again.

It beca a cycle.

Use new enhancent → beco even smarter → find flaws in the version created by the less smart → rebuild → beco smarter again → repeat.

Every day I got a bit faster, a bit more perceptive, a bit more aware.

What was previously unthinkable beca "reasonable."

What was previously genius-level beca "acceptable."

And what once made feel dumb?

Now I laughed at it.

I didn’t tell anyone about this. Not even Tsunade.

I just kept reading. Updating diagrams. Scribbling in my own notes. Modifying scrolls in secret.

Even when she teased for acting smug lately, I brushed it off. Because, well... I was acting smug. I had the right to be.

I wasn’t the idiot trying to morize diagrams and failing anymore.

Now I made diagrams better than the originals.

Even chakra flow mapping techniques that Tsunade’s scrolls described as "too difficult to use in practice"—I could break down and reconstruct them in my head, then draw a more stable version with a couple of tweaks.

I started experinting with fractional chakra layering.

Dynamic enhancent zones.

Neurological chakra compression fields.

It was like looking under the hood of the human mind and learning how to hotwire it for peak performance.

This wasn’t just peak tier chakra control anymore. It was also peak tier chakra application.

I wasn’t training to get smarter.

I made myself smarter, literally.

After three more iterations, I finally settled on a model.

I could now enhance my brain for five full hours a day on the sa chakra budget I used to spend for two.

And the benefits were no longer just intelligence.

My reflexes sharpened.

My instincts got quicker.

I could feel myself planning faster in battle, thinking five or six moves ahead even in basic drills.

I could even predict the future to so extent.

I was finally starting to feel like a prodigy.

But I knew the truth.

I wasn’t one.

I was still the sa Inaba—average in everything except chakra control.

It’s just... now I’d turned that one cheat into sothing ridiculous.

I had just learnt of how to use my cheat properly now.

If there were prodigies who were born at the top of the mountain, I was the guy who started in the valley and climbed with bare hands and a top tier rope.

And now?

Now I was near the peak.

The only thing stopping now... was my body.

Because here’s the truth I couldn’t ignore anymore:

Physically, I was as average as shinobi co.

Sure, I could run fast, punch boulders, throw kunai straight through wooden posts.

But that was all chakra reinforcent.

My actual strength? Average.

Speed? Average.

Chakra reserves?

...Let’s not even talk about that.

Compared to clan kids, I was basically running on a weak battery pack.

So, I decided...

It was ti to change that.

My brain was fixed.

My mind was supercharged.

Now it was ti to upgrade the body and my chakra amount too.
