Chapter 4: Hidden Potential

The Uchiha compound library was exactly where Sasuke had expected it to be—in a small, unassuming building adjacent to what had once been the clan's administrative center. He'd been putting off this particular exploration, not entirely comfortable with delving into the remnants of the clan's knowledge when he wasn't truly an Uchiha by blood or birth. But as graduation approached, he knew he needed every advantage he could get.

The library door opened with a protesting creak, dust motes dancing in the thin beams of morning light that filtered through dirt-streaked windows. Nobody had entered this place since the massacre. Even ANBU investigators had apparently left the clan's scrolls and books untouched, perhaps out of respect, perhaps out of fear of clan-specific traps or seals.

"Let's see what secrets you're hiding," Sasuke murmured, running his fingers along a shelf of ancient-looking scrolls.

The room was smaller than he'd anticipated, but densely packed with knowledge. Shelves lined every wall from floor to ceiling, crammed with scrolls, books, and loose papers carefully preserved in protective cases. A large table dominated the center of the room, its surface covered in a fine layer of dust that showed no fingerprints or disturbances.

Sasuke spent the first hour simply organizing and cataloging, trying to make sense of the library's layout. The Uchiha, it seemed, had been methodical record-keepers. Everything was labeled and categorized—clan history, Fire Country politics, battle tactics, mission reports, and most importantly for his purposes, jutsu theory and training methods.

One locked cabinet at the far end of the room, marked with the Uchiha fan and additional seals, presumably contained information on the Sharingan and clan-specific techniques. Sasuke eyed it thoughtfully but decided to leave it for another day. Without the Sharingan actually awakened, many of those techniques would be useless to him anyway.

Instead, he focused on a promising section labeled "Foundational Training." Here, he found scrolls detailing chakra control exercises far more advanced than what was taught at the Academy.

"Perfect," he murmured, carefully unrolling a particularly promising scroll titled "Chakra Refinement: Beyond the Basics."

The scroll detailed exercises for improving chakra precision, efficiency, and stamina—all areas where Sasuke knew he needed improvement. While his body had the muscle memory for basic chakra manipulation, truly mastering it required the mental understanding that Andrew had never had the opportunity to develop in his previous life.

He spent the next several hours absorbed in study, taking careful notes in a blank journal he'd brought for this purpose. Some of the exercises seemed deceptively simple—variations on leaf sticking that involved rotating the leaf while maintaining contact, or transferring chakra from one point on the body to another in specific patterns.

Others were far more complex, involving chakra flow visualization techniques that would eventually lead to nature transformation abilities. One particularly interesting section described methods for sensing one's own chakra reserves more accurately, which would help prevent exhaustion during intensive jutsu usage.

By mid-afternoon, Sasuke's eyes were strained from reading faded script, and his head was swimming with new information. He carefully re-rolled the scrolls he'd been studying, placing them in a small pile to take back to his apartment.

As he prepared to leave, a thin, unmarked book caught his eye, partially hidden behind a larger tome on the history of Konoha's founding. Curious, he pulled it out and opened to the first page.

"Personal Training Journal of Uchiha Kagami," he read aloud, surprised. This wasn't an official clan document but someone's private notes.

Flipping through the journal, Sasuke found detailed observations about training methods, particularly focused on taijutsu development without reliance on the Sharingan. Kagami—whoever he had been—had apparently believed that too many Uchiha became dependent on their doujutsu, neglecting foundational combat skills.

"An Uchiha who can fight effectively even when chakra-depleted is more valuable than one who crumbles without their Sharingan," one passage stated firmly. "The eye is a tool, not a crutch."

Sasuke smiled faintly. This Kagami seemed to have been unusually pragmatic for an Uchiha. The journal contained detailed breakdowns of stances, footwork patterns, weight distribution principles, and counter-techniques against various common fighting styles found in the Five Great Nations.

This was exactly the kind of resource Sasuke needed. While the original Sasuke had been a taijutsu prodigy, much of that skill had been intuitive or developed through the Sharingan's copying ability. Andrew, lacking that background, needed the explicit technical understanding this journal provided.

He added it to his pile of materials to take home, then made one final sweep of the library to ensure he hadn't missed anything immediately useful. Satisfied with his haul, Sasuke secured the building and headed back to his apartment to begin practicing some of the simpler exercises he'd discovered.

The next morning, Sasuke rose before dawn. The Academy was closed for a teacher training day, giving students a rare free day mid-week. He intended to make the most of it, starting with implementing some of the chakra control exercises he'd studied.

After a light breakfast, he made his way to a secluded training ground on the outskirts of the village. Training Ground 22 was small and relatively basic, lacking the specialized features of the more popular areas. It was perfect for his needs—quiet, private, and unlikely to be used by others, especially at this early hour.

The morning air was crisp and cool as Sasuke began with standard warm-up exercises, then moved into the first chakra control technique from the scroll. It involved channeling a precise amount of chakra to his fingertips, enough to create a small visible aura but not so much as to discharge into the air.

Controlling chakra this precisely proved more challenging than he'd anticipated. Sasuke's body knew how to mold and direct chakra for standard techniques, but this level of fine manipulation required concentrated mental focus that he was still developing.

After an hour of practice with mixed results, Sasuke took a short break. He was making progress, but slower than he'd hoped. The scroll had warned that these exercises required patience and persistent practice—true mastery might take months or even years.

As he drank from his water bottle, a faint sound caught his attention—the distinctive thud of fists hitting a training post, coming from deeper in the wooded area at the edge of the training ground. Someone else was here, earlier than he would have expected.

Curiosity piqued, Sasuke packed his equipment and moved quietly through the trees toward the sound. As he drew closer, he could make out grunts of exertion accompanying the impacts, and something about the voice seemed familiar.

Pushing aside a branch for a clearer view, Sasuke found himself looking at a small clearing where Naruto Uzumaki was furiously pummeling a wooden training post. The blond boy was drenched in sweat, his knuckles raw and bleeding, his face set in a grimace of determination.

Sasuke stayed hidden, observing with interest. He'd never seen Naruto practicing alone like this in the anime or manga. The usual portrayal was of a lazy prankster who avoided serious training until motivated by direct competition or crisis. But the boy before him had clearly been at this for hours, given his exhausted state and the blood-stained training post.

What caught Sasuke's attention more than Naruto's unexpected dedication, however, were the numerous flaws in his technique. His stance was unbalanced, his weight distribution all wrong, his punches off-center and likely to cause more damage to his own hands than to an opponent. He was working incredibly hard, but in all the wrong ways.

It explained a lot about Naruto's poor performance in Academy sparring matches despite his formidable stamina and determination. Nobody had ever corrected his basic form. Without proper guidance, all his effort was being channeled inefficiently.

Sasuke debated with himself for several minutes. Should he intervene? The original Sasuke would never have bothered, viewing Naruto as an annoyance at best, a rival at worst. But Andrew knew Naruto's potential, knew the hero he would become with proper training.

And more importantly, Andrew had been the kind of person who helped others when he could.

Decision made, Sasuke stepped into the clearing. "Your stance is all wrong."

Naruto jumped and spun around, eyes wide with surprise then narrowing in suspicion. "What are you doing here, Sasuke? Spying on me?"

"I was training nearby and heard you," Sasuke replied calmly. "You've been at this for hours, haven't you?"

Naruto's chin lifted defensively. "So what if I have? Some of us have to work hard, not like you who gets everything perfect the first time."

The bitterness in his voice was palpable, and Sasuke felt a pang of sympathy. The gap between their academic standings wasn't entirely due to natural talent—Sasuke had the advantage of a proper clan upbringing before the massacre, training from skilled relatives, and access to resources Naruto had never been given.

"Nothing's perfect the first time," Sasuke said, stepping closer. "But you're wasting effort with poor technique. You'll hurt yourself before you ever hurt an enemy that way."

Naruto scowled, bristling at the criticism. "Like you care. Just leave me alone. I don't need your help."

"Fine," Sasuke shrugged, turning as if to leave. "Keep punching wrong. Keep losing every spar. Your choice."

He took three deliberate steps toward the trees, silently counting down in his head. Three, two, one...

"Wait."

Sasuke turned back, carefully keeping his expression neutral despite his internal satisfaction. Naruto's pride was warring visibly with his desperate desire to improve.

"What's... wrong with my stance?" Naruto finally asked, the words clearly difficult for him to voice.

"Several things," Sasuke said, walking back. "Your feet are too close together, which makes you easy to unbalance. Your weight is forward when you punch, which reduces power and control. Your wrists aren't aligned properly, which is why your knuckles are bleeding—you're hitting at the wrong angle."

Naruto looked down at his stance, then at his raw knuckles, uncertainty replacing his usual bravado. "Oh."

"The Academy teaches the basic form, but Mizuki-sensei never corrects you specifically," Sasuke observed. "Why is that?"

A shadow crossed Naruto's face. "He doesn't like me. None of the teachers do except Iruka-sensei, and he's too busy with the whole class to help me individually."

The simple statement, delivered without self-pity but as a mere fact of life, reminded Sasuke of the village's treatment of young Naruto. The boy who would one day save them all was currently being deliberately sabotaged by the very people tasked with teaching him.

"Show me your basic Academy stance," Sasuke instructed, pushing aside his anger at the injustice.

Naruto complied, moving into what he clearly thought was the standard defensive position taught at the Academy. The form was barely recognizable—feet at the wrong angles, hands positioned incorrectly, balance completely off.

"That's... not even close to right," Sasuke said, unable to hide his surprise. "Who showed you that?"

"Nobody," Naruto admitted, dropping the stance. "I watch from the back of the class and try to copy what I see. But the teachers usually tell me to stop disrupting things if I ask questions."

Sasuke stared at him, a new understanding dawning. Naruto wasn't just untaught—he was being actively prevented from learning. The dead-last of the Academy wasn't failing due to lack of talent or effort, but because the system itself was rigged against him.

"Okay," Sasuke said, making a swift decision. "I'll show you the correct forms. Basic stance first, then we'll fix your punches."

Naruto's eyes widened in surprise. "You... will? Why would you help me?"

It was a fair question, one Sasuke had anticipated. The original Sasuke would never have offered assistance to his self-proclaimed rival.

"Because we're both orphans," he said after a moment. "And because no one should be deliberately held back from reaching their potential."

Something shifted in Naruto's expression—surprise, confusion, and then a flicker of what might have been understanding. "You noticed too, huh? That they treat me different?"

"It's hard to miss," Sasuke replied, moving into position beside Naruto. "Now, watch carefully. Basic defensive stance looks like this."

He demonstrated the proper form, feet shoulder-width apart, weight centered, hands positioned to protect vital areas while remaining ready to strike or block.

"Try to mirror me," he instructed.

Naruto attempted to copy the stance, with limited success. His foot positioning was better, but his upper body still looked awkward and tense.

Without thinking, Sasuke reached out to manually adjust Naruto's posture, tapping his elbow to bring it in closer, nudging his foot to the correct angle. He'd done the same countless times with newer players in gaming tournaments in his previous life, helping teammates optimize their ergonomics for better performance.

Only after several adjustments did he realize that Naruto had frozen, a strange expression on his face.

"What?" Sasuke asked, stepping back.

"Nothing," Naruto said quickly, but his voice sounded odd. "Just... no one's ever helped me like this before."

The simple statement hit Sasuke with unexpected force. Of course. In a village where most adults either ignored or actively disliked him, where peers followed their parents' example, Naruto would have little experience with friendly physical contact or one-on-one instruction.

"Well, they should have," Sasuke said gruffly, feeling suddenly awkward. "You're a student of the Academy, same as anyone else."

Naruto's usual grin returned, though his eyes remained suspiciously bright. "Yeah, well, their loss! I'm gonna be Hokage someday, and then they'll all be sorry they didn't teach me properly, believe it!"

Naruto tensed slightly after his declaration, clearly expecting the usual mockery or dismissal his dream typically received from peers and adults alike. When Sasuke didn't immediately scoff or roll his eyes, Naruto's expression shifted to one of genuine surprise.

"You won't become Hokage with that stance," Sasuke pointed out instead, redirecting to the task at hand. "Try again. Feet wider, back straight."

Naruto's eyes widened, not at the criticism of his form, but at the implicit acknowledgment of his dream as something possible—something that merely required proper training rather than being dismissed as ridiculous fantasy. For a moment, he just stared at Sasuke, momentarily speechless.

"You... you didn't say it was stupid," he finally said, his voice uncharacteristically quiet.

"What?"

"That I want to be Hokage. Everyone always laughs or tells me to stop being an idiot when I say that."

Sasuke shrugged, somewhat uncomfortable with the naked vulnerability suddenly visible on Naruto's face. "The Fourth Hokage had to start somewhere. So did the Third. No one's born wearing the hat."

A slow, genuine smile spread across Naruto's face—not his usual exaggerated grin, but something softer and more sincere. "Yeah... yeah, you're right!"

For the next hour, Sasuke guided Naruto through basic forms, correcting his positioning, demonstrating proper technique, and explaining the principles behind each stance and movement. To his surprise, Naruto proved to be a dedicated and attentive student once he got past his initial defensiveness.

"You're actually not bad at this," Sasuke admitted as Naruto successfully executed a basic combination they'd been practicing. "You pick things up quickly when they're explained properly."

Naruto beamed at the rare praise. "Really? You think so?"

"Your main problem is that no one taught you the fundamentals," Sasuke said. "Once you have those down, your natural stamina and reflexes will make you formidable."

The compliment seemed to both please and embarrass Naruto, who scratched the back of his head with a nervous laugh. "Yeah, well... thanks for showing me. I didn't expect you of all people to help me."

"Like I said, we're both orphans," Sasuke replied, beginning his cool-down stretches. "And we're both going to be ninja of Konoha. The village is stronger when all its shinobi are properly trained."

Naruto regarded him thoughtfully as he copied Sasuke's stretches. "You've been different lately. Less of a jerk."

"Maybe I'm growing up," Sasuke suggested. It was easier than explaining that he was literally a different person occupying Sasuke's body.

"Maybe," Naruto agreed, though he still looked puzzled. "So... will you show me more tomorrow? I mean, if you're not busy or whatever."

Sasuke considered the request. On one hand, spending time training Naruto would take away from his own practice. On the other, helping the future hero of Konoha develop his skills earlier could only benefit the village in the long run. And on a more personal level, Andrew had always enjoyed teaching others—whether it was helping younger kids at the cat café or guiding new players in online games.

"I can spare an hour in the mornings," he decided. "But you have to promise to practice properly on your own. No point teaching you if you're going to fall back into bad habits."

"I promise!" Naruto exclaimed, his face lighting up with genuine excitement. "I'll practice everything exactly like you showed me!"

"Good," Sasuke nodded. "Meet here tomorrow at sunrise. Don't be late."

As they gathered their things to leave, Sasuke noticed Naruto casting surreptitious glances his way, as if trying to solve a particularly confusing puzzle.

"What?" he finally asked.

"Nothing," Naruto said quickly. "Just... thanks, Sasuke. For real."

The simple gratitude, free of Naruto's usual bluster or competitiveness, caught Sasuke off guard. He nodded awkwardly in acknowledgment, unsure how to respond.

They walked back toward the village in companionable silence, parting ways at the main road. As Sasuke headed toward the Uchiha compound, he reflected on how drastically he was already changing the original timeline. The antagonistic rivalry that had defined early Sasuke and Naruto's relationship was being replaced by something closer to reluctant friendship—or at least mutual respect.

What consequences would that have for future events? Would Team 7's dynamics be completely different? Would Naruto still develop the same determination to bring Sasuke back if he ever left the village? Would Sasuke even make the same choices that led to his departure in the original story?

There was no way to know. All he could do was continue making the choices that felt right to him—the choices Andrew would have made, tempered by the reality of the world he now inhabited.

The next week fell into a new routine. Early mornings with Naruto, working on basic taijutsu forms and gradually introducing simple combinations. Academy classes during the day, where Sasuke noticed Naruto beginning to apply some of what they'd practiced, though still holding back enough to not raise suspicion. Afternoons in the Uchiha library, continuing his research into chakra control and expanding to other areas of interest. Evenings practicing the techniques he'd studied.

On the fifth day of their training arrangement, Sasuke arrived at the clearing to find Naruto already there, diligently practicing the forms they'd worked on the previous morning.

"Your left elbow is still dropping too low," Sasuke observed as he approached, setting down his equipment bag.

Naruto jumped slightly, then grinned. "Morning to you too, jerk. I've been at this for an hour already."

"Impressive," Sasuke acknowledged, genuinely meaning it. Naruto's dedication, once properly directed, was remarkable. "Show me the combination from yesterday."

Naruto performed the sequence of movements—a basic block-strike-sweep pattern designed to create openings in an opponent's defense. His execution was significantly improved from the previous day, with only minor flaws in his footwork.

"Better," Sasuke nodded. "Your weight transfer is smoother. You've been practicing."

"Believe it!" Naruto exclaimed, his usual catchphrase accompanied by a proud grin. "I did this for three hours last night after dinner. My neighbors started banging on the walls 'cause of the noise, but I didn't stop!"

Sasuke snorted, amused despite himself. Naruto's enthusiasm was infectious in its own way.

"Today we'll focus on defensive techniques," he said, dropping into the basic ready stance. "Most Academy students attack recklessly, without protecting themselves. If you can block effectively and counter-strike, you'll have an advantage."

They spent the next hour working through various defensive maneuvers—blocks, parries, evasive footwork. Naruto struggled more with these than with offensive techniques, his natural inclination being to attack rather than defend.

"This is boring," he complained after failing to properly execute a particular block for the fifth time. "When do we get to the cool moves?"

"When you master the basics," Sasuke replied firmly. "Cool moves won't help you if you can't defend yourself from a simple straight punch."

Naruto grumbled but returned to his practice. After several more attempts, he finally performed the block correctly, his face lighting up with satisfaction.

"There, see? I did it!"

"Once," Sasuke pointed out. "Now do it fifty more times until your body remembers it without your brain having to think about it."

"Fifty?!" Naruto exclaimed. "That's excessive!"

"That's training," Sasuke countered. "Do you think the Hokage got where he is by doing things once and calling it good?"

The mention of the Hokage title had the intended effect. Naruto's complaints ceased immediately, replaced by determined focus as he began repetition after repetition of the defensive technique.

As Naruto practiced, Sasuke moved through his own exercises, implementing some of the chakra control techniques he'd been studying from the Uchiha scrolls. One particularly challenging exercise involved creating a thin layer of chakra between his palm and a leaf, then gradually reducing the amount of chakra used while still maintaining the leaf's position.

He was so absorbed in the precision required that he almost missed Naruto's voice.

"What are you doing with that leaf? Some kind of special technique?"

Sasuke looked up to find Naruto watching him curiously, momentarily distracted from his defensive drills.

"Chakra control exercise," Sasuke explained, maintaining his focus on the leaf hovering just above his palm. "More advanced than what they teach at the Academy."

"Can you show me that too?" Naruto asked, his eyes bright with interest.

Sasuke hesitated. On one hand, Naruto's chakra control in the original timeline had been abysmal at this age. On the other hand, much of that could be attributed to the same lack of proper instruction that had hindered his taijutsu development. And given the enormous chakra reserves Naruto possessed as the Nine-Tails' jinchūriki, any improvement in his control would yield significant benefits.

"It's advanced," Sasuke warned. "You should master the basic leaf-sticking exercise first."

"I never really got that one," Naruto admitted, scratching the back of his head. "The teachers moved on before I figured it out."

Again, evidence of the systemic sabotage of Naruto's education. Sasuke suppressed a flash of anger.

"Alright, we'll start with the basics then. Come here."

Naruto eagerly moved closer as Sasuke picked up another leaf from the ground.

"The standard exercise is sticking the leaf to your forehead using chakra," Sasuke explained. "But the Academy instruction is actually inadequate. They tell you to channel chakra to your forehead, but they don't explain how to regulate the amount."

"Yeah, I always end up using too much and the leaf either shoots off or gets crushed," Naruto confirmed.

"Exactly. The key is to start with more chakra than you need, then gradually reduce it until you find the minimum required to maintain contact."

Sasuke demonstrated, placing the leaf against his forehead and channeling a visible amount of chakra—far more than necessary, causing the leaf to glow slightly. Then, slowly, he reduced the flow until the leaf was held in place by just the right amount of energy.

"See? Now you try. Start with more than you think you need, then back it off slowly."

Naruto took the leaf, placed it against his forehead, and scrunched his face in concentration. The leaf immediately blasted off, shooting several meters into the air before fluttering back down.

"Whoa!" Naruto exclaimed. "Did you see that? It went super high!"

"Too much chakra," Sasuke noted, retrieving the leaf. "Way too much. Try again, but imagine you're opening a faucet just enough for a small trickle, not a full blast."

Naruto tried again, with similar results. And again. And again. On the fifth attempt, the leaf didn't shoot off but instead crumpled against his forehead as if crushed by invisible pressure.

"Better," Sasuke encouraged. "Still too much, but you're getting closer. Keep trying."

They continued this way for another half hour, making minimal progress. Naruto's chakra control was even worse than Sasuke had anticipated, likely due to both lack of proper instruction and the enormous reserves he unconsciously drew from. Every attempt used drastically more chakra than required.

"This is impossible!" Naruto finally exclaimed after his twentieth failure. "I'm never going to get it!"

"It's not impossible," Sasuke countered calmly. "It's just difficult for you specifically because you have unusually large chakra reserves."

Naruto blinked in surprise. "I do?"

Sasuke realized his mistake immediately. At this point in the timeline, Naruto had no idea about his status as a jinchūriki or the reason behind his massive chakra capacity.

"It's obvious from how much you're using without even trying," Sasuke covered smoothly. "Most Academy students struggle to use enough chakra. Your problem is the opposite—you use too much without meaning to. That actually indicates above-average potential."

"Really?" Naruto's frustration transformed instantly into excited pride. "So I'm actually good at chakra?"

"You have a lot of it," Sasuke clarified. "Being good at using it will take practice. But having large reserves is definitely an advantage for a ninja."

Naruto beamed, then looked thoughtful. "Is that why I can never do the Clone Jutsu right? I'm using too much chakra and it messes them up?"

Sasuke nodded, impressed by the insight. "Exactly. The standard Clone Jutsu requires precise control. With your reserves, it's like trying to fill a teacup from a waterfall."

"Huh," Naruto seemed to absorb this, a rare contemplative expression on his face. "So I need to practice control more than most people."

"Yes. And it will be harder for you than for others. But if you master it, you'll be capable of much more powerful techniques because of your large reserves."

This was dangerous territory, Sasuke realized. He was coming very close to revealing future knowledge. But helping Naruto understand his own chakra nature seemed important enough to risk it.

"We should get back to the village," Sasuke said, noting the position of the sun. "Academy starts in an hour."

As they packed up their equipment, Naruto remained unusually quiet, clearly processing the new perspective on his chakra difficulties.

"Hey, Sasuke," he finally said as they started walking back. "Thanks again for... you know, explaining stuff. No one's ever told me I might actually be good at something before."

The simple statement, delivered without Naruto's usual bombast, hit Sasuke hard. It was a stark reminder of how isolated and discouraged the future hero had been during his childhood.

"You have potential," Sasuke said honestly. "You just need proper instruction."

Naruto's responding smile was smaller than his usual grin, but somehow more genuine. "Same time tomorrow?"

"Same time tomorrow," Sasuke confirmed. "And bring a bunch of leaves. You're going to master that exercise if it takes all week."

Naruto groaned dramatically, but his eyes shone with determination. "Fine, fine. But after I get it, you have to teach me something cool, deal?"

"Deal," Sasuke agreed, allowing himself a small smile.

As they parted ways near the village center, Sasuke reflected on how quickly their dynamic had evolved from hostile rivalry to something approaching friendship. It wasn't the path the original Sasuke would have taken, but it felt right to him.

And who knew? Perhaps a Naruto with better fundamental skills and a more supportive early relationship with his future teammate would be even more formidable than the one from the original timeline. Only time would tell.

For now, Sasuke had his own training to focus on. The scrolls he'd borrowed from the Uchiha library still contained many techniques to master, and graduation was approaching rapidly. Whatever changes he made to this timeline, he needed to be prepared for the challenges that awaited—many of which would come much sooner than most of his classmates could possibly imagine.
