Midnight enveloped Konoha in a blanket of stillness, but inside Naruto's modest apartment, the air vibrated with a stifling heat.
Sitting in the center of the wooden floor he himself had polished hours before, Naruto kept his eyes closed. His breathing was a slow, deep bellow. Beneath his skin, the tiny flow of blue chakra had been forced to take on a dark scarlet hue under the influence of the Chaos Refinement Technique. He was attempting to push the limits of his physical vessel, seeking to break the barrier between the initial and middle stages of Body Tempering.
However, as the internal fire reached his bones, a sharp, silent warning echoed in his mind.
Naruto instantly halted the flow of energy. He opened his eyes, exhaling a blast of hot air that rippled the space in front of his face. A bead of cold sweat trickled down his temple.
"Impossible," he muttered to himself, staring at the palms of his hands, which trembled slightly from the strain. "I was arrogant. My soul remembers the feeling of possessing an invulnerable body, but this mortal vessel is barely a clay pot drying in the sun. If I force the advance to the middle stage without the support of spirit pills or a medicinal bath of beast marrow, my own muscles will tear apart and my bones will turn to dust."
In the Immortal World, cultivation was a path that defied the heavens, but even the heavens had rules. Balance was absolute. He couldn't build a thousand-story tower on a foundation of mud.
He stood slowly, allowing the dull ache in his overworked muscle fibers to dissipate. If the inner path to power was temporarily blocked by his body's fragility, then he would have to resort to the external path.
Kakashi Hatake wasn't an opponent he could defeat with physical strength alone in the initial stage of Body Tempering. He needed tools. He needed the laws of the world carved on paper.
Naruto walked to the small desk in the corner of his room. Rummaging through the drawers he had tidied that very afternoon, he found what he was looking for: a couple of blank Academy scrolls, a half-used inkwell, and a rough-bristled brush. Materials of the lowest quality imaginable.
In his past life, as the personal disciple of the Master of the Pure Jade Sect and eventually as an entity on the cusp of godhood, Naruto had had access to unimaginable resources. Dragon's Blood Ink for writing, paper woven from celestial lotus silk, and brushes made from the fur of nine-tailed spirit foxes.
And yet, as his calloused, mortal fingers held the cheap wooden brush from the Ninja Academy, a feeling of profound and utter familiarity washed over him.
He closed his eyes, letting the memories of his four hundred years flow. In the Immortal World, there were sword geniuses, alchemical prodigies, and martial arts monsters. But the path of Arrays and Talismans was considered the most esoteric and difficult of all. It required an almost godlike understanding of the laws of the universe to capture the energy of the heavens in a few strokes of ink. Ancient masters spent centuries meditating on a single runic symbol.
But for Naruto, it was never a struggle.
From the first time he picked up a spirit brush in the Immortal Realm, runes flowed from his hand as naturally as breathing. He grasped defensive arrays, suppression seals, and elemental talismans with an ease that terrified even his own teachers. He never knew why. He always assumed it was a karmic blessing or a whim of the Dao.
Now, standing in this mortal world, in the body of a despised Konoha child, the truth was stirring like a whisper in his blood.
It wasn't heaven that bestowed this talent upon me, Naruto thought, feeling the thump of his own heart, the dense, stubborn vitality that resided in his lineage, far older than his memories as a ninja. It's this body. It's my blood. Even when my soul crossed the void and lived for centuries in another universe, the resonance of my ancestors traveled with me. The art of sealing and tracing... it's my birthright.
The Uzumaki clan. The absolute masters of Fūinjutsu. His immortal soul and mortal body were finally beginning to synchronize.
Naruto unrolled the rough paper on the desk and uncapped the ink. He had no natural energy at his disposal, no spiritual blood. He had only his tiny, condensed reserve of chakra, purified by the Refinement of Chaos.
He held the brush suspended above the paper. His breath became imperceptible. The room fell into a deathly silence.
And then, the paintbrush descended.
There was no hesitation. Naruto's wrist moved with the fluidity of water running over stones and the precision of an executioner's sword. As the ink touched the paper, Naruto channeled a microscopic, almost invisible thread of his chakra through the wooden handle to the bristles.
Top stroke: Energy anchor.
Middle stroke: Weight condensation.
Bottom stroke: Activation trigger.
The final flick of his wrist sealed the symbol. For a fraction of a second, the black ink glowed with an icy blue radiance before drying instantly, fusing with the paper fibers.
Naruto let out a soft sigh. He had created a Lesser Gravity Talisman. In his past life, a talisman of this rank would have been junk he wouldn't even use to light a campfire. But here, with his limited resources, it was a tactical miracle. If he managed to attach it to Kakashi's body, the Jōnin would experience a sudden increase of thirty kilograms of pure weight on his muscles, enough to alter his center of gravity for a critical instant.
He didn't stop there. For the next four hours, Naruto worked in a state of absolute concentration. His ink was running out, and his already small pool of chakra was dangerously dwindling to a mere puddle.
By the time the sky outside his window began to be tinged with the first gray and purple hues of dawn, Naruto had five rectangles of paper on his desk.
Two Lesser Gravity Talismans.
Two Kinetic Absorption Talismans (designed to dissipate the force of a direct physical impact, protecting his fragile, mortal bones).
One Breath Concealment Talisman (a one-time-use seal that would erase his presence and chakra signature for exactly ten seconds).
He was physically exhausted, his energy reserves depleted, but his mind was a lake of complete calm. He carefully folded the talismans and concealed them in the inner pockets of his sleeves and the lining of his orange jacket.
He didn't sleep. Instead, he sat in the lotus position for the last hour before leaving, breathing deeply to gather just enough energy to move without fatigue.
At five o'clock in the morning, the mist still clung to the ground of Konoha. The streets were deserted, populated only by the shadows of buildings and the silence of mortals still asleep, unaware of the vast laws that governed the universe.
Naruto walked along the dirt streets with silent steps. The morning breeze stirred his blond hair, but his blue eyes stared straight ahead with glacial serenity. He felt no nervousness. He felt no anxiety. He was about to meet a veteran assassin, but his soul held the calm of one who had survived the wrath of the Four Eternal Saints.
The trees began to thicken as he moved away from the village center, until the dense forest opened up to reveal a wide expanse of grass, a nearby river, and three tree stumps lined up in front of a solitary memorial stone.
Training Ground Number 7.
When Naruto arrived, he didn't announce his presence. He simply stepped out from the line of trees.
Sakura sat on the ground, hugging her knees and yawning widely, dark circles under her pale face. She had clearly followed Kakashi's instruction not to eat breakfast, and hunger was already gnawing at her.
Sasuke stood leaning against one of the tree stumps, arms crossed and eyes closed, trying to conserve his energy.
Neither of them noticed Naruto until the blond boy was less than three meters away from them.
Sasuke opened his eyes with a start, his body tensing instinctively. Since when has he been there? the Uchiha thought, a jolt of alarm running down his spine. He hadn't heard his footsteps on the grass. He hadn't even heard the rustle of his clothes.
Sakura blinked, rubbing her eyes. "Oh... hi, Naruto. You're early," she murmured, too tired to unleash her usual string of insults.
Naruto didn't respond immediately. He walked to the tree stump on the far left and sat down on it, his back perfectly straight, his hands resting on his knees. His fingers subtly brushed against the fabric of his sleeves, feeling the texture of the hidden talismans.
He gazed into the dense forest, where the mist was slowly beginning to dissipate.
"The hunter won't arrive until the sun is high," Naruto said, his voice breaking the morning stillness with unwavering certainty. "He's testing the fragility of your mortal minds. I suggest you meditate and conserve your strength, because patience is the first weapon he'll try to break."
Sasuke frowned deeply at the strange cadence of her words, but Sakura simply dropped her head into her knees with a miserable whimper. The stage was set. The trap was laid. Now, all that was missing was the Jōnin.
