Shinichi headed to the Senju Main Residence as usual. Strolling down Konoha's streets, he swung his arms leisurely, a blade of foxtail grass between his lips, and let his lazy gaze wander over his surroundings.
"Looks like the system wants to turn me into an all-rounder..."
Thinking about his mere ten years of life, in which he had gone from a transmigrator to one of the Shinobi World's greatest prodigies, Shinichi pressed a hand to his forehead and sighed. He already possessed Ryujin Jakka, the Six Styles, the Flight Technique, Ice Release, Sealing Jutsu, a sage body, and a fusion of the Six Eyes and Sharingan.
"Ah, I'm only ten, and I'm already almost invincible in the Shinobi World. This damned talent of mine!"
His lips curled slightly, his tone full of self-mockery, though a trace of contemplation about the future lingered deep in his eyes.
The system kept strengthening every aspect of his abilities, leaving him with a vague sense that his existence was probably meant for more than simply enjoying a life of slacking off.
"Ryujin Jakka, the Six Styles, the Flight Technique, Sealing Jutsu, a sage body, Ice Release, the Six Eyes fused with the Sharingan, and even Lightning Release Chakra Mode... isn't this development path a little too well-rounded?"
Shinichi narrowed his eyes. The term "all-rounder" grew increasingly clear in his mind.
"Well, getting stronger isn't a bad thing. I'll just take things as they come."
With that thought, he stretched lazily and continued toward the Senju Main Residence.
At the Senju Main Residence, the fading glow of dusk bathed the mansion that bore Konoha's glorious legacy in warm light.
A figure sat cross-legged in the courtyard, brows slightly drawn and expression focused.
Tsunade, the pride of the Senju Clan and a future member of the Konoha Sannin, was receiving Mito Uzumaki's guidance as she inscribed her own Yin Seal formula.
Mito Uzumaki gently brushed Tsunade's forehead. Wherever her fingertips passed, a special formula slowly emerged, etched into Tsunade's skin like a brand.
"Tsunade, the Yin Seal is a secret technique of the Uzumaki Clan. Only exceptional chakra control and sustained refinement will allow you to master it. Your chakra reserves are more than sufficient, but your control still needs improvement."
Mito's voice was gentle, yet her gaze held a hint of pride.
In the original timeline, Tsunade might not have finished inscribing her Yin Seal until much later. Now, however, thanks to Uchiha Shinichi's constant challenges and unconventional training, her growth had far surpassed its original course!
Taijutsu? She had not only learned the Six Styles, but could already use techniques such as Finger Pistol, Shave, and Moonwalk with ease!
Ninjutsu? She had completely mastered the Rasengan and could even incorporate it into her taijutsu!
Sealing Jutsu? Under Shinichi's "malicious" guidance, she could already skillfully use the Four Symbols Seal and Five-Seal Barrier!
Even her proudest specialty, Medical Ninjutsu, had taken the first steps toward an era-defining breakthrough thanks to Shinichi's early development efforts—
Strength of a Hundred Technique: Creation Rebirth!
This supreme technique, which should have required years of research to complete, had already entered its final refinement stage.
Tsunade slowly opened her eyes, and the formula on her forehead flickered briefly. Mito Uzumaki nodded in satisfaction. "Very good. Keep it steady."
Nearby, Shinichi leaned leisurely against a wooden pillar in the courtyard, arms folded and an amused smile on his lips.
"Well, well, little Tsunade. You really have become impressive."
Tsunade rolled her eyes and huffed irritably. "Don't think I don't know you spend every day slacking off, young clan heir. Once I catch up to you, we'll see how smug you are!"
Shinichi chuckled, his lips curving into a teasing smile as he lounged against the pillar and studied the fuming Tsunade through narrowed eyes.
"You? Catch up to me?"
His languid voice was filled with mockery.
Tsunade planted her hands on her hips and glared at him, arching her brows slightly. "What? You think I can't catch up?"
Shinichi shrugged lazily and gave a deliberate sigh. "Ah... if you really do catch up to me someday..."
He paused, giving Tsunade an amused look as his lips curled slightly. "Then I suppose I'll reluctantly marry you. But once we're married, don't expect me to earn a living and support the family!"
The air instantly froze!
Tsunade stared blankly for a moment. Then her ears gradually turned red, and a barely perceptible mix of embarrassment and anger appeared on her face.
"Y-you! What nonsense are you spouting?!"
She suddenly swung a fist at Shinichi!
Boom!
A jagged fissure split the ground. The force of her punch swept up dust and unleashed gusts of wind, making the surrounding wooden pillars creak and crack, nearly snapping them!
Shinichi had anticipated it. The instant her fist fell, he flickered several meters away, leisurely shook out his sleeves, and teased, "Oh my, Tsunade. Are you embarrassed? Or did I make your heart flutter?"
"Uchiha Shinichi! Get back here!" Tsunade roared, her face as red as a ripe tomato as she moved to chase him.
Watching from the side, Mito Uzumaki could not help covering her mouth and chuckling. "Hehehe, young people certainly are energetic..."
Her gaze swept between Shinichi and Tsunade, full of amusement and knowing meaning.
By then, Shinichi had already used Shave to flash farther away. Grinning, he waved at Tsunade.
"Little Tsunade, future Lord Hokage, you'll need a lot more practice if you want to catch this young clan heir!"
Tsunade clenched her fists and gritted her teeth. "...Just you wait. One day, I'm going to beat you into the ground!"
Shinichi blinked, his smile deepening as he said meaningfully—
"Sure. I'll be waiting for that day. But be careful—the loser will have to keep their promise, you know?"
Tsunade froze, then realized which "promise" Shinichi meant. The blush on her face instantly spread down her neck!
"Uchiha Shinichi! I'm going to kill you!"
Watching the scene, Mito Uzumaki's smile grew wider. She shook her head and sighed. "Young people... they really are entertaining."
Shinichi stopped teasing Tsunade and turned toward Tobirama Senju's laboratory.
This place was one of the greatest "treasure troves" in the entire Shinobi World!
As he pushed open the heavy metal door, the faint scent of ink, tinged with dust, greeted him.
The laboratory was spacious and deep. Bright chakra lamps set into the walls illuminated rows of neatly arranged bookshelves and scroll cabinets.
A dazzling array of ninjutsu, Forbidden Jutsu, secret scrolls, experimental records, and unfinished research hypotheses had all been meticulously filed away, awaiting someone destined to explore and decipher them.
Shinichi looked around, his eyes glinting faintly.
Tobirama Senju was one of the greatest scientists, Forbidden Jutsu masters, and Sealing Jutsu masters in the Shinobi World's history. In a sense, the research he had left behind was more terrifying than sheer combat power.
"Flying Thunder God, Impure World Reincarnation, the Multiple Shadow Clone Technique, the Body Flicker Technique, sealing formations... any one of these studies could unleash a bloodbath in the outside world."
Shinichi slowly approached the central workbench. A thick research notebook lay on it, its title page bearing a line of small, elegant yet forceful handwriting:
"Ninjutsu theory and practical combat analysis: Tobirama's notes"
Shinichi's lips lifted slightly. He casually turned a few pages, and unfamiliar ninjutsu models and theories of chakra circulation immediately came into view.
"...Interesting. Old man Tobirama really is a monster."
His gaze swept across the materials and quickly settled on a Sealing Jutsu research scroll—an experimental report on modifying the structure of soul chakra.
"If this research succeeds, it might help me develop a more complete system of combined powers, or even further refine my soul's power. Then Ryujin Jakka really will have the power to destroy heaven and earth!"
He narrowed his eyes, his gaze growing more fervent.
This laboratory might be the key to breaking through his own limits.
"Old man Tobirama, I won't stand on ceremony about using what you left behind."
Shinichi chuckled softly, ran his fingers over the scroll, and immediately immersed himself in studying it.
Just as Shinichi was thoroughly engrossed in his reading, Tobirama Senju silently appeared at the laboratory entrance.
Shinichi instinctively raised his head and looked at the figure whose back had gradually begun to stoop.
Tobirama Senju, one of the Shinobi World's greatest scientists, a creator of Forbidden Jutsu, and a former battlefield legend, was now inevitably approaching the end of his life.
He was no longer as tall and imposing as he had once been. The white Hokage cloak over his shoulders stirred faintly in the breeze. He looked more exhausted than before, and even his steps had grown heavier.
Shinichi's heart tightened slightly.
He had long since noticed that Tobirama was sleeping for longer and longer. Sometimes he would briefly falter during training, and occasionally... he could not even hold his teacup steady.
His life really was probably nearing its end.
Shinichi had always prided himself on his composure, but at that moment, a trace of sorrow still slipped unconsciously into his eyes.
Tobirama Senju keenly caught that emotion.
He smiled faintly, his voice as steady and authoritative as ever. "You need not grieve over my death. Instead, turn those feelings into strength to protect Konoha."
"Don't flatter yourself. Who would grieve over your death, you rotten old man?" Shinichi stubbornly retorted, trying to hide the unfamiliar emotions in his heart.
Tobirama merely smiled and gave him a meaningful look without arguing.
Silence briefly settled between them.
"Oh, right, old man. Look—my Sharingan!" Shinichi abruptly changed the subject, raising a hand to cover one eye before slowly opening the other.
His azure One-Tomoe Sharingan rotated gently, radiating a mysterious, unfathomable light.
Tobirama Senju's pupils contracted slightly.
A blue Sharingan?
This is... a mutated Sharingan!
He had studied the Sharingan extensively, yet had never encountered anything like this.
Normally, an awakened Sharingan was scarlet. Shinichi's eye, however, was as clear as a sapphire. The instant it activated, Tobirama even sensed a strange fluctuation unlike that of an ordinary Sharingan.
"Does it have any new abilities?" Tobirama asked eagerly, suppressing his astonishment.
Seeing that research fanatic's expression, Shinichi's lips lifted into a sly smile.
"Want to know? Trade me the Flying Thunder God Technique."
Tobirama Senju raised a brow and snorted, his tone carrying a hint of disdain. "Hmph. The Flying Thunder God Technique scroll is on the second shelf behind you. You simply failed to notice it!"
Shinichi froze, then whipped his head around toward the bookshelf—
Sure enough, on the second shelf, he spotted a specially sealed scroll.
...This thing was here the whole time?!
The corner of Shinichi's mouth twitched. Suddenly, he did not know whether to laugh or cry.
No wonder old man Tobirama wasn't worried about me secretly learning his techniques. He'd already given me full access!
He reached out and took down the Flying Thunder God Technique scroll, then looked at Tobirama with a complicated expression.
The old man had never said it aloud, but from the moment he had brought Shinichi into the laboratory, he had already decided—
To let him learn everything here.
"You planned to let me learn Flying Thunder God all along?" Shinichi sighed softly, setting aside his flippant attitude for once.
Tobirama Senju smiled faintly, his voice carrying a rare warmth. "You have the talent to inherit it. But since you didn't look for it yourself, I naturally wasn't going to offer to teach you."
Shinichi fell silent for a moment, then his lips lifted and he chuckled softly.
This old man really is as awkward as ever.
"All right, since you're being so generous..."
Shinichi slowly closed the scroll in his hands, his gaze deep and his lips curving into a confident smile.
"Then it's time I showed you my new ability."
The laboratory's testing ground.
The spacious underground chamber was enclosed by sturdy, chakra-reinforced walls, and the lighting bathed the entire area in brilliant white.
Tobirama Senju stood with his hands behind his back, quietly watching Uchiha Shinichi across from him.
Shinichi slowly activated his Sharingan. The One Tomoe in each sapphire-blue eye rotated gently, and a faint excitement showed in his gaze.
He assumed the opening stance of the Gentle Fist.
Tobirama paused, a trace of confusion crossing his eyes.
"Gentle Fist?"
That's the Hyuga Clan's taijutsu. It requires the Byakugan to strike an enemy's chakra points precisely. How can Shinichi use it?
Isn't he an Uchiha?
Before Tobirama could consider it further, Shinichi moved!
His figure darted forward like a phantom, closing in on Tobirama as fast as lightning. His palms flew, his movements precise and fierce!
"Eight Trigrams—Air Palm!"
Shinichi thrust out a palm. A fierce chakra shock wave surged forth instantly, sending a muffled boom through the air.
Tobirama's gaze sharpened. He pushed off the ground and vanished from where he stood, barely evading the blow with the Body Flicker Technique.
But—
"Too slow, old man Tobirama."
A smile lifted Shinichi's lips. He abruptly appeared behind Tobirama and struck precisely toward the Heavenly Pillar chakra point on his back!
This is actually the Byakugan's ability to see through things in all directions!
Startled, Tobirama twisted sharply to evade, but his weakened body was ultimately a step too slow.
Smack!
The palm landed, instantly disrupting Tobirama's chakra circulation. Though it was not completely sealed, the chakra inside him clearly faltered.
"...Just as I thought."
Tobirama fell silent for a moment, having already reached his answer.
Shinichi's Sharingan had actually incorporated the Byakugan's penetrating vision!
This ability meant that Shinichi not only possessed the Sharingan's motion tracking, but could also perceive an enemy's chakra flow like the Hyuga Clan—and even pinpoint their chakra points!
Moreover, he could use the Gentle Fist system!
What kind of talent was this?
"How did you do it?" Tobirama stared deeply at Shinichi, inwardly shaken.
Shinichi slowly withdrew his hands, brushed off his sleeves, and chuckled. "Honestly, I don't know either. Maybe heaven favors me..."
Tobirama fell silent.
As the Shinobi World's most rational scientist, he did not believe in such things as "heaven's favor."
But now, faced with Shinichi's growth, he had to admit—
This boy might truly have been chosen by heaven.
He not only possessed the Uchiha bloodline, but also the Byakugan's abilities. He had even mastered Ice Release, and faint traces of a sage body's presence were emerging...
Once someone like him fully matured, he would surely stand at the pinnacle of the Shinobi World!
Tobirama could not help thinking of his elder brother, Hashirama Senju.
That man, too, had once been someone favored by destiny.
Now, that same radiance was beginning to emerge in Shinichi.
Tobirama sighed softly. For the first time, he felt it deep in his heart—Shinichi might truly be Konoha's most important hope for the future.
Inside the testing ground, the air still carried the lingering chakra fluctuations from Shinichi's earlier strike.
Shinichi walked slowly behind Tobirama Senju, extended two fingers, and precisely released his sealed chakra points.
As his chakra began flowing again, Tobirama gently moved his arms, feeling the chakra circulate within him. Then he raised his gaze and looked intently at Shinichi.
"How does it compare to the Byakugan?"
Tobirama asked, his voice as steady as ever, though his eyes betrayed a curiosity and inquisitiveness unlike anything he had shown before.
Shinichi arched an eyebrow, the corners of his mouth lifting slightly. "That curious, are you? Then I'll be generous and tell you."
He raised a hand and pointed at his azure One-Tomoe Sharingan, a mysterious gleam flickering deep within his eyes.
"It's stronger than the Byakugan."
Tobirama's gaze sharpened slightly.
"My ability to track movement is better than the Byakugan's, and my range is greater. It even exceeds the Byakugan's maximum scouting distance." Shinichi paused, then continued with a hint of amusement, "Besides, unlike the Byakugan, the world I see..."
"Is in color."
Tobirama's pupils contracted slightly.
—Color vision?
The Byakugan offered monochrome X-ray vision. It could perceive chakra flow and see through obstacles, but it could not distinguish colors.
Yet Shinichi's eyes not only tracked movement more effectively, but also retained full color vision while seeing through objects?
What did that mean?
It meant that Shinichi's visual information was more comprehensive and more three-dimensional than the Byakugan's. He could analyze battlefield information faster and more accurately than a Byakugan user!
For a shinobi, visual precision determined how quickly they could make combat decisions. Shinichi's eyes not only combined the Sharingan's motion tracking with the Byakugan's ability to see through objects, but also overcame the Byakugan's shortcomings in tactical analysis, scouting, and perception!
"...To think they could do that." Tobirama murmured, staring intently into Shinichi's eyes as though he wanted to see through them completely.
In all his years, he had never seen a Sharingan that had mutated like this!
Tobirama could not help pondering it. The Uchiha's Sharingan evolved through emotional upheaval and combat experience, yet Shinichi's had only just awakened and already displayed such astonishing traits...
If these eyes continued to evolve, what would they become?
Feeling Tobirama's piercing gaze, Shinichi chuckled and waved a hand. "What's wrong? Don't tell me you're jealous that I'm more of a genius than you?"
Tobirama snorted, his tone as cold as ever. "You're too arrogant, Shinichi."
Shinichi shrugged casually, his tone flippant. "Whether I'm arrogant or not, you'll find out eventually..."
With that, he blinked softly. His azure Sharingan with its tomoe slowly deactivated, returning his eyes to their original black.
Yet Tobirama did not look away for a long time.
He watched Shinichi in silence, his thoughts churning.
—In any era, talent like this would become the greatest variable in the Shinobi World.
—The era of Hashirama Senju and Madara Uchiha had already passed, and this boy before him might well become the next powerhouse capable of shaking the balance of the Shinobi World!
"...Your future may be even more unpredictable than you imagine."
Tobirama murmured to himself, his voice barely audible.
Before you continue
