The mechanical chime hadn't just echoed in Evan's ears; it had vibrated through his very marrow. For a long, breathless moment, he remained frozen in the center of his dark bedroom, his hands still warm with the first flickers of his newly refined Chakra.
In the silence, the blue translucent screen continued to pulse with a soft, ethereal light, illuminating the dust motes dancing in the air.
[Ding!]
[Compatible energy system detected within the Host's body. Beginning analysis…]
[World coordinates confirmed. System initialization in progress…]
The text scrolled across his vision with a clinical, unfeeling speed.
[1%… 12%… 46%…]
Evan watched the numbers climb, his heart hammering a frantic rhythm against his ribs. This was it. The missing piece. In his previous life, he had read countless stories where the protagonist was whisked away to a fantasy world, only to be saved by a "Cheat" or a "System." He had waited four years for this. He had trained until his muscles screamed and his lungs burned, all while nursing the quiet, nagging fear that he was truly alone in this world—that there would be no divine intervention, no shortcut to the top of the food chain.
[99%… 100%.]
[Initialization complete.]
[Hello, Dear Host. The Doctor's Benevolence System has been successfully installed. I will now serve you wholeheartedly.]
Evan slumped slightly, the tension leaving his shoulders in a rush of air. "Wholeheartedly, huh?" he whispered, his voice raspy in the quiet room. "You took your sweet time getting here."
He waited for a response, perhaps a sassy AI voice or a guide to walk him through the menus, but the system remained silent. He spent the next hour testing the limits of this new presence in his mind. He asked questions, shouted internally, and tried to visualize a personality for it.
Nothing.
The system was a tool, not a companion. It was a cold, logic-driven interface that responded only to specific prompts or actions. It wasn't intelligent in the human sense, but as Evan navigated the sub-menus that flickered into existence at his thought, he began to understand the sheer, terrifying potential of what he now possessed.
As the name suggested, the Doctor's Benevolence System was built upon a single, core pillar: healing.
In a world defined by the "Art of the Kill," Evan had been gifted the "Art of the Save."
The mechanics were straightforward yet profound. Whenever Evan used the healing techniques granted by the system to treat another person, he would receive random rewards. It was a transactional form of karma. You give life, and the world—or at least the system—gives back.
He scrolled through the list of potential rewards. The variety made his head spin.
Physical Attributes: Strength, Agility, Constitution, and Spirit.Chakra Proficiency: Mastery over his energy flow and reserves.Ninjutsu: From simple D-rank utility spells to the forbidden S-rank techniques.Bloodline Fragments: The most coveted prize. Pieces of the genetic puzzles that made the Uchiha, the Senju, and the Hyuga legends.
If he extracted the same reward twice, the system wouldn't waste it. Instead, it would convert the duplicate into "Experience Points," which could be used to manually level up his existing skills.
But the real kicker—the thing that made Evan's breath catch in his throat—was the "Benevolence Store." It was a marketplace where he could spend "Benevolence Points," a special currency earned through high-quality healing, to buy items that defied the laws of the ninja world.
The quality of the rewards was tied directly to the "Value" of the patient. The system even provided a set of "Theoretical Milestones" to illustrate the scale.
[Task: Train with Pain — Reward: Six Paths Chakra (Fragment)]
[Task: Heal Pain — Reward: Six Paths Chakra (Complete)]
[Task: Heal Naruto Uzumaki — Reward: Sage of Six Paths Chakra]
Evan stared at the name Naruto Uzumaki.
Right now, that name belonged to a four-year-old boy, much like himself, who was likely wandering the village in search of a warm bowl of ramen or a kind word. To the system, however, Naruto wasn't just a boy; he was a vessel for the ultimate power of this world.
Evan's mouth went dry. His mind raced with the possibilities. If he could position himself as the village's premier medic—if he could become the one person the heavy hitters of this world relied on for their lives—he wouldn't just be surviving the Fourth Great Ninja War. He would be the one dictating its terms.
But wait, Evan thought, forcing himself to settle. Calm down. Right now, you're just a four-year-old with a 1.2-meter reach. You can't even heal a scraped knee yet, let alone the Sage of Six Paths.
He knew this world too well to become arrogant. Power was a double-edged sword. In Konoha, being too useful or too powerful without the right backing was a death sentence. He thought of Danzo Shimura and the Root—the "Darkness of the Shinobi" who would happily pluck Evan's eyes out or seal his tongue if he proved to be a threat or a valuable tool.
The system raised his lower limit. It gave him a floor to stand on. But the ceiling? That still depended on his own sweat and blood.
"If I'm lucky," he muttered, "the Six Paths might actually be within reach. But first... I need to see if this thing actually works."
He looked around the room, his eyes landing on a standard-issue kunai he had bought at a general store a few months prior. The metal was dull, but it was still steel.
He picked it up, feeling the weight of the weapon in his hand. He hesitated for a second, the primal part of his brain screaming at him to stop. Then, with a sharp intake of breath, he pressed the edge against his left forearm and pulled.
Sssst.
A clean, shallow line opened on his skin. Crimson blood welled up instantly, beaded, and then began to trickle down his arm, staining the floorboards.
"Hiss—!"
The pain was sharp and cold. Evan dropped the kunai and immediately focused his mind. He didn't have to search for a jutsu; the system responded to his intent.
Doctor's Benevolence: Minor Restoration.
A soft, emerald-green glow erupted from his right palm. It was a color so vibrant it felt alive. He pressed his hand over the cut. The sensation was bizarre—it felt like a thousand tiny, cool needles stitching his flesh back together. It didn't just numb the pain; it erased it.
Within seconds, the glow faded. Evan pulled his hand away.
The blood was still there, smeared and drying, but beneath it, the skin was perfectly smooth. There wasn't even a scar. It was as if the injury had never happened.
"That's... incredible," Evan whispered. He had seen medical ninjas in the distance before, but their healing usually took time and significant effort. This had been nearly instantaneous. More importantly, the drain on his newly formed Chakra was negligible. It was like taking a single sip of water from a deep well.
He waited for the reward screen. A notification for his bravery? A boost to his constitution?
Silence.
"System?" he prompted. "If I heal myself, what do I get?"
[Ding!]
[Test treatment complete. Physical Attribute +0.3]
[Thank you for discovering system functionality. As a bonus, the Host will receive a 'System Discovery' gift.]
[Note: Self-healing is considered a basic survival instinct and will not grant rewards in the future. Rewards are only generated through 'Benevolence' toward others.]
[Reward obtained: Insect Nectar.]
Evan stared at the small, glass vial that appeared in his hand. It contained a thick, golden liquid that smelled faintly of rotten fruit.
"Insect Nectar?" he repeated, his eye twitching. "I stabbed myself... for bug food?"
The system didn't answer.
Evan sighed, setting the nectar on his bedside table. "Fine. No cheating the system by becoming a masochist. I get it."
He took a deep breath, trying to regain his composure. "Alright. Open the attribute panel. Let's see where I actually stand."
A new screen flickered to life.
Character: Evan Kamiyo
Age: 4
Constitution: 6.3 (Physical health, durability, recovery)
Spirit: 10.4 (Mental strength, willpower, resistance)
Chakra: 1.5 (Total reserves)
(Note: An average graduating Genin standard is 10 in all categories.)
Skills:
Chakra Refinement Lv.1 (1/100)
Affinities:
Wind, Thunder
Items:
Bloodline Awakening Potion (Novice Gift)Insect Nectar
Evaluation: Below average. A fragile seedling in a forest of predators.
Evan winced at the evaluation. Fragile seedling. It was a harsh assessment, but a fair one. His Spirit was high—likely because he possessed the soul and memories of an adult man—but his physical body and Chakra reserves were pathetic. Even with his years of training, he was barely halfway to the level of a child who had just graduated the Academy.
But then his eyes locked onto the "Novice Gift."
In the world of Naruto, talent wasn't something you worked for; it was something you were born with. You either had the "God Genes," or you didn't.
Evan reached out and tapped the icon for the Bloodline Awakening Potion.
A vial filled with a swirling, deep-blue liquid appeared in his palm. It felt heavy, vibrating with a low-frequency hum that he could feel in his teeth.
"This is it," he whispered. "The equalizer."
He didn't hesitate. He uncorked the vial and downed the contents in a single gulp.
For a heartbeat, nothing happened. The liquid tasted like iron and ozone.
Then, the world exploded.
Evan's eyes flew open, but he saw nothing but white light. His blood suddenly felt like it had been replaced with molten lead. Every cell in his body seemed to expand and contract at once, a violent, microscopic restructuring of his very DNA.
He tried to scream, but his throat was locked. He collapsed onto the floor, his fingers clawing at the wood as his bones groaned under the sudden, massive influx of vitality.
This was the Senju bloodline.
It wasn't the diluted, fading lineage of the modern era. This was the raw, primal essence of Asura, the Sage of Six Paths' younger son. It was the "Body of the Sage"—a fountain of life force that turned a mortal frame into a vessel for infinite endurance and massive Chakra.
The transformation lasted only a minute, but to Evan, it felt like an eternity. When the heat finally receded, he remained on the floor, gasping for air, his skin coated in a thin layer of dark, foul-smelling impurities that his body had purged.
He felt... different.
The air in the room didn't just feel like air anymore; he could feel the pressure of it against his skin. His hearing was sharper—he could hear the distant scuttle of a beetle in the walls and the rhythmic breathing of a neighbor three houses down.
But most of all, he felt the fire.
His Chakra was no longer a small, flickering candle in his gut. It was a roaring furnace.
He shakily stood up and called for the panel again.
Character: Evan Kamiyo
Age: 4
Constitution: 9.5
Spirit: 11.4
Chakra: 11.5
Evan stared at the numbers in disbelief. A single potion had nearly tripled his physical stats and increased his Chakra reserve nearly tenfold.
At four years old, he now possessed the raw power and energy of a Genin who had spent years training at the Academy.
He stepped out into the courtyard, the cool night air hitting his heated skin. He felt light—dangerously light. He threw a simple punch into the air, and the crack of the displaced wind was audible.
"So this is what it feels like," he murmured, clenching his fist. "This is the 'Genius' starting line."
He looked up at the moon, his mind already spinning with the future. The system was a godsend, but the Senju bloodline was his foundation.
He knew the trap that many transmigrators fell into. They relied entirely on their "Cheats," becoming lazy and complacent. They forgot that in the ninja world, a system could give you a sword, but it couldn't give you the killing intent or the reflexes to use it when an Uchiha's blade was at your throat.
"The system gives me the lower bound," Evan said to the stars, his voice hardening. "But I will define the upper bound."
He wouldn't stop his physical training. If anything, he would double it. He would squeeze every drop of potential out of this new Senju body. He would master the wind and the thunder. He would become a doctor who could heal the world—and a warrior who could survive it.
He sat back down in the dirt of his courtyard, closing his eyes to begin a new round of Chakra refinement. The "warmth" was no longer a trickle; it was a tide.
"First order of business tomorrow," he thought as he drifted into a meditative state. "I need to find someone to heal."
He had a village full of ninjas who lived in a state of constant, low-level injury. All he needed was a patient.
