Naruto: I Am Uchiha Sasuke!?

Sasuke walked to the window, gazing out into the darkness of the night.

"In a few days, it will be the graduation exam for the Academy..."

His thoughts drifted. Would the teams be assigned based on grades, or would he still be placed under Kakashi?

The exam itself was hardly a challenge. With his talent, securing first place was a given. Based on performance, he would be assigned to Konoha's number one technician—Hatake Kakashi.

Sasuke had to admit, Kakashi was one of the most respectable figures in the original timeline. A strong and capable ninja, and someone whose character had few dark stains.

But there was no time to dwell on such matters—he had to get stronger as soon as possible. Danzo, Obito, Orochimaru, the Akatsuki... too many powerful forces were lurking in the shadows, waiting for the right moment to strike.

The time he had to grow strong, to exact revenge, and to shape the future of the ninja world, was limited.

With that in mind, it was time to test his greatest advantage—his Cheat.

His heaven-defying comprehension allowed him to grasp, refine, and innovate upon any ninjutsu, technique, or knowledge at an absurd pace. It was a talent that defied common sense, allowing him to achieve enlightenment through deep contemplation.

But comprehension alone wouldn't be enough. While it enhanced his ability to master ninjutsu and strategy, it had little effect on his physical body, chakra reserves, or taijutsu. Those would require dedicated training.

"If a worker wants to do his job well, he must first sharpen his tools."

And the foundation of all power was chakra.

To become stronger, he had to start with the fundamentals.

Sasuke sat cross-legged on the floor, closed his eyes, and focused inward. His mind searched for the flow of chakra within him.

Chakra was a fusion of the body's physical and spiritual energies. It coursed through 361 chakra points across the body's meridian system, forming the basis of all jutsu.

As a ninja's strength increased, their chakra would become denser and their reserves would expand.

Sasuke's goal was clear—he needed to create the most efficient chakra refinement method.

His mind sharpened. His perception deepened.

And then, like a floodgate opening, inspiration surged within him.

[You have deeply comprehended chakra flow, merged various refinement techniques, and achieved enlightenment.]

[You have created the Infinite Chakra Refining Method!]

[Infinite Chakra Refining Method]: Every moment, mental energy commands all 60 trillion cells in the body to refine chakra continuously. Over time, this enhances chakra density, improves control, and steadily increases chakra reserves.

Sasuke's eyes snapped open, a grin forming on his lips.

"This is incredible..."

This technique shattered common sense.

For ordinary ninjas, strengthening chakra required years of constant training. They had to refine chakra step by step, through rigorous practice and meditation.

But this method defied those rules.

Even while eating, sleeping, or resting—his body would continue refining chakra!

With this, he could grow stronger simply by existing.

The power of ninjutsu was dictated by chakra reserves and density. Uchiha Madara's fire jutsu wasn't terrifying just because of technique—it was because his chakra had been honed through countless battles, reaching an intensity beyond Kage-level.

Right now, Sasuke's chakra reserves were standard for a Genin. His Great Fireball Jutsu was no more than an average attack.

But with this method, his chakra would quickly rise to Chunin-level, then Jonin, then Kage-level... and beyond.

Eventually, he would reach reserves comparable to a Tailed Beast. Perhaps even surpass them.

"Genius? Sorry, I'm simply built different."

He smirked and resumed his practice.

…

But soon, his stomach let out a loud growl.

"Damn... I'm starving."

Sasuke sighed as he stood up, rubbing his stomach. He had been so engrossed in refining chakra that he forgot it consumed energy.

"Right... chakra refinement burns calories. If I don't replenish my energy, I'll pass out."

Since he couldn't yet absorb natural energy, he had to rely on food for sustenance.

This was a small flaw in his otherwise perfect technique—it turned him into a big eater.

"Looks like I'll have to learn Sage Mode in the future."

Walking into the kitchen, he opened the refrigerator and checked its contents.

A few steaks. Some rice balls. Tomatoes.

That was it.

Sasuke's gaze darkened.

Back then, the Uchiha clan had been one of the wealthiest and most powerful families in Konoha. Their influence was vast, their resources nearly limitless.

But after the massacre, all of their property, wealth, and assets had been seized by the village's higher-ups.

He, the last surviving heir, had received almost nothing.

If not for a few hidden Uchiha strongholds that still held some stashed funds, he would have been left to starve on the streets.

The thought enraged him.

The Uchiha clan had co-founded Konoha. And yet, in the end, they were exterminated like criminals, their corpses desecrated, their Sharingan stolen.

How vile.

How utterly disgusting.

Sasuke clenched his fists, suppressing the hatred bubbling within him.

If he had been any weaker, the weight of this injustice would have broken him.

But in this life, things would be different.

Strength.

Without it, nothing else mattered.

Pushing down his fury, Sasuke took a deep breath, grabbed the ingredients, and began cooking.

He would eat. He would train. He would grow stronger.

And one day...

They would all pay.
