Chapter 5
Sabo soon learned that Sasuke was a strict yet incredible teacher.
He didn’t sugarcoat anything or give them false encouragement, but instead offered genuine support and practical guidance.
When they succeeded, Sasuke’s praise was rare but meaningful, and when they failed, he pushed them to learn from their mistakes rather than dwell on them.
“Good effort,” Sasuke said one day after Sabo managed to channel a small amount of chakra into his hands. His tone was calm, but the hint of approval in his words made Sabo feel accomplished. “But your control is sloppy. Focus on steadying your breathing and try again.”
Though Sasuke’s training was tough, Sabo found it rewarding. He respected how Sasuke’s teachings always felt purposeful, his methods designed to build their confidence without inflating their egos.
“He doesn’t just tell you what you want to hear,” Sabo remarked to Ace one day as they practiced together. “He tells you what you need to hear.”
Ace grinned, wiping sweat from his brow. “Yeah, that’s Sasuke for you. He’s tough, but he’s the best.”
One thing Sasuke quickly realized was that Sabo had much better patience than Ace. This made Sasuke consider that Sabo might have the potential to learn the Strength of a Hundred Seal Jutsu—a technique that required incredible self-control and the ability to sit still for long periods while carefully storing chakra.
Unlike Ace, who could barely sit still for five minutes without fidgeting or complaining, Sabo showed a natural focus. He was able to meditate and practice chakra control exercises for extended periods without losing concentration.
Sasuke observed him one evening, watching as Sabo maintained a steady flow of chakra to his hands with remarkable precision. It was clear to Sasuke that Sabo possessed the discipline required for such an advanced technique.
“You might be suited for something more advanced,” Sasuke said, his voice calm but thoughtful. “The Strength of a Hundred Seal Jutsu requires patience and precision—traits you already have.”
Sabo blinked in surprise. “What’s that?”
Sasuke explained the Strength of a Hundred Seal Jutsu to Sabo in a calm, detailed tone.
“The Strength of a Hundred Seal Jutsu is a technique where you store vast amounts of chakra into a specific point on your body—most often on the forehead—over an extended period,” Sasuke began, gesturing to his own forehead as an example. “When the seal is complete, it manifests as a rhombus-like marking. This mark isn’t just for show. It represents immense chakra reserves that the user can release when needed.”
Sabo listened intently, nodding along. Sasuke continued, his voice steady but clearly impressed by the jutsu's mechanics.
“With this seal, your already sharp chakra control becomes even more refined. You can use techniques with almost no wasted energy. And when you release the seal, the stored chakra floods your body. It amplifies your strength, speed, and the power of your techniques significantly.”
Ace, sitting nearby, scratched his head. “Wait, so you just keep stuffing chakra into your forehead for years? That sounds boring.”
“It’s not for someone like you,” Sasuke said bluntly, earning an exaggerated pout from Ace before continuing. “The seal remains permanently on the forehead, so the user can keep benefiting from its effects even after releasing it.”
Sabo raised a hand, curiosity gleaming in his eyes. “What about the slug you mentioned earlier? How does that work?”
Sasuke inclined his head slightly in acknowledgment of the question. “This seal has a unique connection to the summoning creature, Katsuyu. With it, the user can perform powerful healing techniques, even spreading healing across large groups of people through Katsuyu. The seal also enables long-distance communication with the slug.”
Sasuke's expression grew slightly more serious. “And when combined with the Creation Rebirth Technique, the user gains access to the Ninja Art Creation Rebirth — Strength of a Hundred Technique. It’s one of the strongest regeneration techniques ever created. But it’s not something to take lightly. Mastery requires discipline, patience, and an unwavering commitment to the process.”
Ace whistled low, looking at Sabo. “Good luck sitting still for that long.”
Sabo smirked, undeterred. “I think I can handle it.”
“Then we’ll begin with chakra storage exercises.” Sasuke nodded approvingly.
Ace doesn't have that patience so he didn’t participate instead he was trying to learn the lightning jutsu.
Sasuke watched with a mixture of admiration and disbelief as the two seven-year-olds effortlessly wielded chakra, manipulating it as if it were second nature to them.
It was impressive to witness, especially given how quickly they had adapted to the training. There were no struggles, no signs of frustration. Once they discovered what they were good at, they were unstoppable.
Sabo, ever the calm and thoughtful one, had gravitated toward Tsunade and Sakura’s style of ninjutsu.
He focused on precise chakra control, healing techniques, and strengthening his body.
He worked methodically, just like Sakura. His approach was steady, focused, and disciplined, always thinking ahead, calculating every move, and making sure every technique was executed flawlessly.
Sasuke could see the potential in him to be a true medic-nin, able to heal even the most serious injuries with a steady hand.
On the other hand, Ace was a different story.
The reckless fool, always rushing into things without thinking too much, had followed more of Sasuke's path. He preferred raw power, charging headfirst into battle with the intensity and determination that was characteristic of his spirit.
Ace had started learning some of Sasuke's more daring techniques, focusing on precise, powerful attacks with a calculated edge. The boy was constantly pushing his limits, testing his strength and abilities in a way that made Sasuke both proud and concerned.
Sasuke couldn’t help but be impressed by their progress. They were both so different, yet both had found their own way, their own method to harness chakra.
Despite Ace's natural talent for combat, Sasuke was determined to push him in a different direction. The brat needs to learn more control, he thought, his eyes narrowing slightly as he watched Ace leap around, showing off his fire jutsu. Sasuke didn’t want Ace to grow up reckless and reliant only on his explosive strength. “You’re learning medical ninjutsu today,” Sasuke called out, his voice flat.
Ace groaned loudly in response, his head hanging. “I know, I know,” he muttered. “But I’d rather be training fire jutsu... or something else.”
“Don’t argue,” Sasuke snapped back. “I don’t care if you can launch fireballs. You need balance. Combat is only one part of being a ninja. Learn to heal, and you’ll be a better fighter in the long run.”
While Ace sulked, Sabo, on the other hand, was entirely different. The calm, focused boy was eager to learn everything Sasuke taught him.
It wasn’t difficult to convince him to study combat, given how naturally patient and determined he was. Sabo was more than willing to listen, absorb, and apply what Sasuke taught him about strategy, strength, and tactical thinking in combat.
"Ready to go over the taijutsu?" Sasuke asked, giving Sabo a nod.
Sabo smiled faintly, nodding. "Of course, Sensei. I'm ready."
While Ace was reluctantly doing medical ninjutsu, Sabo was training his taijutsu with Sasuke. In fact Ace was great at medical ninjutsu, he didn’t hate it but it just he dislikes theories he has to read, analyze it before writing a report.
After a month of separate training, Sasuke finally decided it was time to have Ace and Sabo practice together. His goal was to ensure that both of them were on the same level before allowing them to spar and train side by side.
Much to his delight, the duo’s practice sessions turned out to be a perfect blend of learning. Sabo, with his calm and patient nature, found himself teaching Ace the value of slowing down and focusing. Ace, ever the energetic and fiery type, was more than happy to teach Sabo the techniques that required speed and explosiveness.
As the days went on, their training sessions became more balanced. Ace learned to be more patient, using his newfound control to better execute his techniques, while Sabo became more confident with the explosive power of the Fireball and Lightning Jutsu, techniques that were outside of his usual controlled style.
“Good work,” he said, his voice steady, though there was a hint of approval in his tone. “You two are improving rapidly—much faster than I did at your age.”
Ace and Sabo exchanged surprised glances at the compliment. It wasn’t often that Sasuke praised them directly, and hearing it from him was both unexpected and encouraging.
“You really mean that?” Ace asked, grinning widely, wiping sweat off his forehead.
Sasuke gave a rare, small nod. “I do. You’ve both shown impressive growth. Ace, you’ve learned to focus, even if you still like to rush things at times. And Sabo, you’ve been pushing your limits, adapting techniques that weren’t in your comfort zone.”
Sabo smiled faintly, a bit humbled by Sasuke’s words. “Thanks... We’ve been working hard.”
The next day, as the sun began to rise over their makeshift training grounds, Sasuke called the boys together. They had just finished their morning warm-up, and they were still catching their breath when Sasuke looked at them seriously, his expression as calm and unreadable as ever.
"Listen up," he began, his voice steady. "We’re going to another island to practice medical ninjutsu. It’s time you both moved beyond reading books and using the techniques on animals."
"Like last time?" Ace perked up, his eyes bright with excitement. He still remembered the time when the two of them had gone around to random places to heal people. For those who were wealthy, they had asked for compensation, but for those who were poor, they had never asked for anything in return.
Sabo’s eyes gleamed with excitement as he remembered Ace telling him their previous journey before Sabo stayed with them. He remembered the week-long adventure where Ace and their sensei had gone around various islands, healing people in need. Ace had shared that they treated everyone, regardless of their wealth—those who could afford it were asked for a small donation, while the poor received their help without any expectation in return.
Sabo couldn’t help but admire Sasuke even more after hearing this. He had always known their sensei was impressive, but hearing that he was using his powerful medical ninjutsu to heal without asking for anything in return was truly remarkable. Sabo understood the value of medical ninjutsu firsthand, having been trained in it by Sasuke, and the idea of using such power selflessly for the benefit of others resonated deeply with him.
He had eagerly awaited this moment for a long time.
As Sasuke noticed the excitement in both of his students, he smiled inwardly. “Pack your things,” he said. “We’ll be going to another island for a week to practice.”
The two of them, eager to put their skills to the test, packed in ten minutes. Sasuke then placed a hand on each of their shoulders and teleported the three of them away. They arrived on a snow-covered island, a stark contrast to the warmth of their previous home.
Sasuke handed each of them a winter jacket with the Uchiha symbol on it. They adjusted to the cold quickly, ready for the task at hand.
Over the next week, they traveled around the town, silently treating those who were ill or injured. Sasuke focused on those who had more serious conditions or rare diseases that required special treatment. Ace and Sabo took care of the others—those who didn’t need immediate attention but still needed help.
As they worked, the townspeople quietly whispered about the mysterious figures who had arrived. The tales of the legendary doctor, long thought to be a mere folk legend, now seemed real. What had once been a story of a young, freckled boy with silver eyes and his older companion with raven hair, a handsome, young man with raven hair and strange eyes, now includes one more boy with blond hair.
The townspeople were careful not to speak too openly, fearful that the noble class or Celestial Dragons might hear. They had learned the hard way on another island how dangerous it could be to talk about the doctor. That island’s people had made the mistake of revealing too much, which had led to the Celestial Dragons attempting to seize the doctor for their own use. But the doctor had vanished, disappearing without a trace, just as he had appeared.
The same applied to encounters with pirates or marines. Whenever they crossed paths with the mysterious doctor, they kept quiet, often even helping him leave without causing any trouble.
Despite countless attempts by people from all backgrounds to track the doctor down, they never succeeded.
It was as if he didn’t exist—though, of course, he did. The one person who knew where to find the doctor, and who kept the secret, was none other than Monkey D. Garp.
Sasuke sighed in relief, while Sabo and Ace slumped down on the ground painting harshly as they had almost used up their chakra in order to bring back the man from death.
After resting for a minute Sasuke left to inform the man’s kid that his father was saved.
He didn’t understand why someone would kill a skilled doctor just to obtain his devil fruit? Although he wasn’t able to keep the devil fruit within the man, but his life was saved.
Somewhere in the Minion island.
A man lying in the crimson-stained snow before him. The figure was as unusual as the island itself, dressed in eccentric clothing that seemed more suited to a masquerade ball than the harsh, frozen wasteland of Minion Island.
The man’s shaggy golden-blonde hair was matted with blood, his pale skin now almost ghostly under the fading light of the day. Sharp, reddish-brown eyes stared upward, glassy but defiant, framed by the dark red lipstick that extended in eerie lines from the corners of his mouth. Over his right eye, a dark blue star-shaped tattoo stood stark against his skin, as if mocking the situation he was in. His feathered mantle, deep purple against the snow, was tattered and soaked through, barely clinging to his shoulders.
Gunshot wounds riddled his body, seeping red into the pure white ground beneath him, yet he still wore a faint smile. It was the smile of someone who had accepted the inevitability of death but wasn’t entirely at peace with it.
Donquixote Rosinante let out a pained sigh as his entire body was in unbearable pain.
He wondered if Law had gone far away, he wasn’t sure but even so he will stay alive until he can’t so that he can buy time for the kiddo he thought as his own child can get away from here.
Rosinante was brought out of his thoughts by footsteps coming near him, he opened his eyes just in time to see two boys around 7 years old crouch down on his both sides.
The blond haired kid on his right side while raven haired kid on his left side.
“Sabo, this guy can open his eyes!” the raven-haired boy exclaimed, his voice lively despite the concern etched on his face. He leaned closer, wide-eyed, as if amazed Rosinante was still conscious.
The blond boy, Sabo, rolled his eyes. “Of course he can, Ace. He’s not dead yet—just knocking on death’s door.”
A soft chuckle escaped Rosinante’s lips at their interaction, though the effort sent a jolt of pain through him. He barely reacted as small, warm hands lifted his left arm, two fingers pressing against his wrist to check his pulse. For someone so young, the boy’s actions were methodical, almost practiced, though Rosinante couldn’t help feeling a hint of doubt.
Ace, the raven-haired boy, was undeterred. With a serious expression, he began listing Rosinante’s injuries, his lively voice oddly contrasting the grim situation. “Internal wounds, a few broken bones, about five bullet wounds, and a lot of blood loss.”
“That’s a lot of injuries you have, old man,” Sabo said disapprovingly, his blue eyes narrowing with concern, looking far too mature for his age. His tone and expression reminded Rosinante of a stern doctor reprimanding a careless patient.
Rosinante couldn’t help but grin at Sabo’s tone, though the look Sabo gave him showed he wasn’t impressed.
Ace, who had been using his chakra to check the man’s body state, let out a snort. “We should first stabilize the blood, before I take out the bullets from his body!”
Sabo turned to Ace, his expression flat and full of doubt. “Since when do you know how to take bullets out of a human body?”
Rosinante also looked at Ace after hearing Sabo’s skeptical voice.
Ace flashed a wide, confident smile, his dark eyes curving upwards. “I don’t!” he declared.
.For a moment, Sabo and Rosinante stared at Ace in complete disbelief. Then Sabo reacted first, sighing as though he carried the weight of the world on his young shoulders. Without hesitation, he reached over and smacked Ace square on the forehead.
“You idiot!” Sabo snapped, his voice a mix of exasperation and worry. “Why would you say it like you actually knew what you were doing?”
Ace rubbed his forehead, grinning sheepishly. “I’m just saying, I’ve seen Sensei do it before! How hard can it be?”
“It’s very hard!” Sabo shot back, his voice rising. He threw his hands up, clearly trying to keep his cool. “Forget taking out bullets—we need to stop the bleeding first! And no, Ace, you are not performing surgery.”
Ace pouted, crossing his arms like a sulking child. “Buttt~ Saboooo, have you forgotten we can use our chakra to take out the bullets? We don’t need any tools for that!” he said, his tone almost sing-song, as if trying to tease Sabo into agreeing.
Sabo froze, his eyes narrowing as he turned to Ace. “Our chakra? Are you serious right now? You barely have control over your own chakra, Ace! What if you make things worse?”
Ace huffed, puffing his chest out in a poor attempt to look confident. “I’m not that bad! I’ve been practicing, you know. I can totally do it.”
“Practicing on what, Ace? On what? A dummy?” Sabo asked, his voice dripping with sarcasm. “This is a real person, not some piece of wood!”
Ace grinned cheekily. “Well, no better time to practice than now, right?”
Sabo slapped a hand to his forehead, letting out an exaggerated groan. “You’re unbelievable.” He stared at Ace for a moment, then sighed, clearly giving in. “Fine. Fine. But if you screw this up, you’re the one explaining it to Sensei.”
Ace’s grin widened as he rubbed his hands together, his excitement barely contained. “Don’t worry, I’ve got this!”
Rosinante, watching the exchange with half-lidded eyes, couldn’t help but let out a weak chuckle, even though it sent another wave of pain through him. These kids were arguing like it was just another day, and yet here they were, trying to save his life. He wasn’t sure if he should be worried or impressed.
Sabo, the smartest and most level-headed of the two, quickly took charge before Ace could suggest another crazy plan. He held up a hand to stop Ace from talking and said firmly, “Okay, here’s the plan. First, we’ll stop the bleeding. Ace, you’ll take out the bullets using chakra, but carefully. While you do that, I’ll stabilize the wounds to stop the blood loss. Once all the bullets are out, we’ll work together to heal his whole body.”
Ace blinked, looking surprised at how quickly Sabo had taken control of the situation. Then, he grinned and gave a thumbs-up. “Got it, Dr. Sabo! I’ll handle the bullets.”
Sabo rolled his eyes but didn’t argue. “Just focus. And don’t try anything flashy, Ace. This is serious.”
“Yeah, yeah, I know,” Ace replied, crouching closer to Rosinante. He placed his hands just above one of the gunshot wounds, his face unusually focused. “Alright, old man, hold still. This might feel weird.”
Rosinante didn’t have the strength to respond, but he gave a faint nod, trusting the boys despite their bickering. He could feel a faint warmth where Ace’s hands hovered, followed by a strange pulling sensation as Ace began using his chakra to draw out the bullets.
