For a six-year-old who had only discovered chakra today...
This was completely absurd.
And I had barely started.
I finally made my way back home.
The moment I closed the door behind me, I let out a long breath.
My mind was still replaying everything I'd seen at the training ground.
The hand seals.
The chakra flow.
The techniques.
Every single detail was etched into my mind.
It wasn't even like having a photographic memory.
That comparison was too weak.
With the Six Eyes, it felt as though everything I had witnessed had been permanently recorded in my brain.
Not just what the shinobi had done...
But how they had done it.
The exact amount of chakra they used.
The direction it flowed.
The points where it gathered.
The subtle changes when they molded it.
Even the inefficiencies in their chakra control.
I sat down on the floor.
"This ability is fucking ridiculous."
Then I remembered something important about the Six Eyes.
In Jujutsu Kaisen, Satoru Gojo's Six Eyes allowed him to perceive cursed energy with such incredible precision that he could use cursed energy with almost no unnecessary waste.
That was why his stamina seemed practically endless.
If chakra worked on similar principles...
I might have an absurd advantage.
But I needed to test that theory.
I stood up.
My eyes moved toward the wall.
"First... basic chakra control."
I placed one foot against the wall.
I focused.
Then I carefully pushed chakra into my foot.
I didn't even need to guess how much.
I could see it.
The exact amount of chakra required to adhere to the surface.
Too little...
And my foot wouldn't stick.
Too much...
And I'd damage the surface or lose my balance.
So I adjusted it.
Perfectly.
I slowly lifted my other foot.
Then placed it against the wall.
I froze.
I was standing vertically.
"Holy shit..."
I took another step.
Then another.
My body remained perfectly balanced.
I walked upward.
One step.
Two.
Three.
I reached the ceiling.
I looked down.
"This is actually easy."
I walked back down the wall without difficulty.
There was barely any chakra wasted.
My Six Eyes constantly monitored the flow, correcting it almost instinctively.
I couldn't help but grin.
"So this is what perfect chakra control feels like..."
For a six-year-old who had only discovered chakra today...
This was completely absurd.
And I had barely started.
Then I brought my hands together.
I remembered everything perfectly.
The hand seal.
The chakra pathway.
The way the chakra was divided.
The exact moment the shinobi had released it.
Nothing was missing.
I focused.
Unlike a normal beginner, I didn't have to blindly push chakra into the technique and hope it worked.
I could see exactly what I was doing.
Every bit of chakra moving through my body.
Every fluctuation.
Every unnecessary leak.
I corrected all of it.
Then I formed the seal.
"Shadow Clone Jutsu..."
I released the chakra.
Poof!
A burst of smoke filled the room.
I stared through it.
As the smoke slowly cleared, a small figure became visible in front of me.
Grey hair.
Black rectangular sunglasses.
Same clothes.
Same height.
Same face.
My face.
I froze.
The clone froze too.
For several seconds, neither of us said anything.
Then I slowly raised my hand.
The clone raised his.
I tilted my head.
He tilted his.
My mouth opened slightly.
"...No way."
The clone crossed his arms.
"Yeah. That's pretty much what I was thinking."
My eyes widened behind my sunglasses.
"It talks too..."
"Obviously I talk," the clone replied. "I'm literally you."
I stared at him.
He stared back.
Then a grin slowly spread across both our faces.
"Holy shit."
"Holy shit."
I walked around him, examining his body with my Six Eyes.
This was nothing like the basic Clone Technique.
There was actual chakra inside him.
A physical body.
A genuine duplicate.
And the chakra distribution...
Perfect.
There was almost no waste during creation.
I looked down at my hands.
I didn't feel exhausted.
Not even close.
"So it really works..."
The Six Eyes weren't increasing my chakra reserves.
They were doing something arguably even more valuable.
They were making sure almost none of my chakra was wasted.
I looked back at the clone.
"So... how do you feel?"
He shrugged.
"Normal."
"No dizziness?"
"No."
"Any weakness?"
"Nope."
I narrowed my eyes.
Interesting.
Then another thought hit me.
One of the most broken aspects of Shadow Clones wasn't even combat.
It was memory.
Everything a shadow clone experienced returned to the original once it disappeared.
My grin widened.
The clone immediately understood what I was thinking.
"Oh, that's dangerous."
"Extremely."
We both looked toward the books sitting nearby.
Then back at each other.
I slowly smiled.
"If this works the way I remember..."
The clone finished my sentence.
"...then we just found a way to train twice as fast."
I paused.
Then looked at my hands again.
"No."
My smile widened further.
"Not twice as fast."
If my chakra control really was this efficient...
I might eventually be able to create far more than one.
"Okay, me."
I pointed toward the clone.
"Observe my eyes. Tell me what you see in my eyes with your eyes."
The clone raised an eyebrow.
"...You want me to look at your eyes?"
"Exactly."
"That's weird."
"Just do it."
He sighed and stepped closer.
I removed my sunglasses.
The moment our eyes met, something strange happened.
The Six Eyes looked back at the Six Eyes.
For the first time since I had awakened in this world, I wasn't simply observing chakra.
I was observing my own perception.
My clone stared directly into my eyes.
At the same time, I stared into his.
And immediately—
My mind was flooded with information.
His eyes were identical to mine.
Bright blue.
Almost unnaturally so.
But there was something else.
Something deeper.
The Six Eyes weren't simply a physical trait.
I could see an incredibly complex network of microscopic chakra activity surrounding the eyes.
The chakra wasn't flowing through the eyes like normal chakra.
It was...
Interacting with them.
I narrowed my eyes.
"What do you see?"
The clone remained silent for a few seconds.
Then he answered.
"Your eyes are weird."
I frowned.
"That's not exactly helpful."
"No, seriously."
He leaned closer.
"I can see chakra around them, but it's not behaving normally. It's like your eyes are constantly processing everything around you."
My expression became serious.
"Anything else?"
He thought for a moment.
"The amount of information you're taking in is insane."
I nodded slowly.
"That's what I thought."
Then I switched perspectives.
I examined his eyes with my own Six Eyes.
And the result was exactly the same.
I could see the chakra pathways.
The microscopic movements.
The energy being processed.
But there was something I couldn't penetrate.
A layer of complexity that my perception could recognize but not fully explain.
I couldn't see the origin of the Six Eyes.
Only what they were doing.
I frowned.
"So even the Six Eyes can't completely analyze themselves..."
The clone looked at me.
"You figured something out?"
"Yeah."
"What?"
I put my sunglasses back on.
"I think we're going to have a lot of fun figuring out what these eyes can actually do."
The clone grinned.
"Now you're talking."
"Okay, me."
I pointed toward the door.
"Go somewhere safe. Somewhere nobody can see you."
The clone nodded.
"What am I doing?"
"Try the Water Bullet Jutsu."
His eyebrows rose.
"Water Bullet?"
"Yeah. Use the technique we observed earlier. Don't come back until you've tried it."
The clone gave me a confident grin.
"Alright."
He walked out of the room.
I watched him disappear down the street before closing the door behind him.
Then I sat down on my bed.
"Let's see if this actually works..."
I waited.
A few minutes passed.
Then ten.
Then twenty.
Nothing.
I was beginning to wonder if the clone had run into trouble when—
Poof!
I suddenly grabbed my head.
"Ah!"
A sharp pressure exploded inside my skull.
It wasn't unbearable.
Just...
A sudden flood of information.
My clone's memories poured into my mind.
I saw the path he had taken.
The trees.
The empty training ground.
The moment he stopped.
Then—
The technique.
I could see exactly what he had done.
The way he gathered chakra.
The way he converted it.
The hand seals.
The timing.
The precise chakra ratio.
Everything.
My breathing became heavier.
"Fuck..."
I rubbed my temples.
The pain was mild, but it was definitely there.
I closed my eyes and waited for the information to settle.
And then I smiled.
"He did it."
First try.
My clone had successfully performed the Water Bullet Jutsu.
And now...
I knew how to do it too.
Not because someone had explained it to me.
Not because I'd practiced it myself.
But because I had experienced it through him.
I slowly opened my eyes.
"This is ridiculous."
The Shadow Clone Technique wasn't just a way to create another fighter.
Combined with the Six Eyes...
It was a training method that could potentially let me experience years of practice in a fraction of the time.
I looked down at my hands.
There was still a faint ache in my head.
"But I need to be careful."
The information had come all at once.
If I created too many clones and had them all learn different things...
My brain might not handle the memories well.
I leaned back against the wall.
Still, despite the headache, I couldn't stop smiling.
"First day in the Naruto world..."
"And I've already learned a new jutsu."
