Naruto : Perfect Control

Although Medical jutsu has a sky-high requirement to even start learning it, since I had decided, I will go through it.

So, I started studying medical knowledge alongside Tsunade.

And let me tell you—

It sucked.

Not because of the subject. The subject was fine, interesting even. Chakra networks, organ systems, pressure points—this was the stuff I needed to master if I wanted to go anywhere near medical ninjutsu.

The biology here was actually quite different from what I remember back on earth, due to the influence of chakra, so it was something new.

So, was learning from the medical books really a problem?

No, the problem wasn't the material. It was me. Yeah… I sucked.

I read one scroll. Took notes. Understood it. Cool.

Then the next day, I forgot half of it. A week later? Gone.

I'd reread things three, four, five times—and still, nothing stuck the way it should've, which was actually normal by human standards back on earth.

But here, I was studying with Tsunade, and she was a different beast altogether.

She'd read something once and then quote it word-for-word the next day like she was born with the scrolls implanted in her skull.

Sure, she'd been studying since she was five, but still—watching a literal child outpace you like that does something to your ego.

At first, I ignored it.

'It's fine. I'll catch up.'

Then I got annoyed.

'She's from a clan. They train differently. They have better teachers.' I comforted myself,

Then came the quiet dread. Now even with the same facilities, I was getting nowhere near her.

It was really disheartening…

Because I wasn't being lazy. I put in the hours. I wanted to get this.

But even with all that, I was starting to feel myself lagging behind…much behind.

This was not a limit in chakra control or physical enhancement or anything like that, which can be remedied with extra training- Nope…

This was something scarier.

Mental limits. I was simply dumber than her…

Memory. Processing. Learning speed.

Tsunade was smart. Really smart. Like, scary smart.

And me?

I was just a guy with average talent and one overpowered passive stat.

And how the hell am I even supposed to raise my IQ?

One afternoon, after Tsunade finished explaining something to me for the third time—something I had read two days ago, mind you—I just sat there in silence.

She walked off to grab something from another room, still chatting about chakra pathways and medical categories and blah blah blah.

Meanwhile, I just… exhaled. Loudly.

'Damn… why can't I just be smarter?'

I leaned back on the mat, looking up at the ceiling of the Senju study room, trying not to feel like a complete moron.

And then, stupidly, I muttered to myself—

'I wish I had a better brain…'

And then…

A thought.

A dumb one.

But a loud one, came into my mind…

'Wait… what if I use chakra enhancement on my brain?'

My whole body sat upright before I even realized it.

'Why the hell haven't I tried that?'

I'd been reinforcing my muscles, my bones, my joints, even my senses to some extent. I could run uphill with pure physical chakra reinforcement.

I'd enhanced my spine to throw off impact during falls. Hell, I could even thread chakra from my shoulder blades like weird extra limbs.

But never once… had I even considered the brain.

Why?

Well, because most people don't think of chakra enhancing their brain as a thing.

And because maybe there's a reason nobody does it.

Maybe it's dangerous. Or impossible. Or just… dumb.

But the moment the idea struck, I couldn't let it go.

I wasn't like the others, sure there were people smarter than me, but this required super high chakra control, and I was sure that no one even came near me when it comes to controlling chakra, my only cheat.

The idea started eating at me, like an itch I couldn't scratch.

'If I can control chakra perfectly—down to the thread, the layer, the particle—then why can't I enhance specific brain regions?'

'What if I strengthen memory-related centres?'

'What if I increase mental processing speed, or clarity?'

It wasn't just some idea now—it was a need for me…

But I wasn't stupid enough to just throw chakra into my skull and hope for the best.

No.

If I was going to do this, I needed to know what I was aiming for.

So, I stopped following Tsunade's study pace.

I stopped trying to memorize everything.

I focused only on one thing—

The human brain.

Tsunade questioned me a lot about why I did that, but I just said that I had an idea and wanted to try it, it would be a surprise if it succeeds.

For the next year, I read only neurology, brain anatomy, cognitive functions, chakra-nerve interactions, cerebral flow patterns—everything even vaguely related to how the brain worked.

It wasn't glamorous.

It wasn't fun.

But slowly, piece by piece, I started understanding what I needed to do.

No, I did not become some world renown expert on the brain, but I knew enough to try enhancing it without harming myself.

I already knew stuff like,

Where the memory centres were.

Where decision-making happened.

What to avoid—what to reinforce.

I even started creating mock diagrams—chakra circuit blueprints for my own head.

And then… it was time.

It was early morning. I'd skipped the usual Academy drills for this.

Just me, alone, at the far edge of the training field, sitting under a tree with my legs crossed, hands resting on my knees.

I let my chakra flow slowly.

No rush.

First, through the spine.

Up the neck.

Into the base of the skull.

Then… into the brain.

And I'll be honest—

It felt weird.

Like a cold, clear wind was blowing through my thoughts.

No pain. No dizziness.

Just… clarity…

The moment the chakra settled into place, something snapped—in a good way.

Suddenly, things that didn't make sense… did.

Everything I'd read over the last year came back in full detail.

Scroll names. Line numbers. Diagrams. Terms I hadn't even known I knew.

And more than that—

Doubts I'd had?

Started answering themselves.

I laughed.

Not a chuckle. Not a smug snort.

A full-on, hands-on-knees, insane-person kind of laugh.

Because I'd done it.

I found it.

My way to grow, sure I was an idiot, but I could use my only talent to compensate for everything.

People had bloodlines. Others had Kekkei Genkai.

Some had tailed beasts. Some had secret clan techniques.

Me?

I had this.

Chakra enhancement… for the win.

And suddenly, the path ahead didn't seem so scary anymore.

The past me was naïve and dumb, but the present me was smart enough to deal with all which came in my way.
