Danzō Shimura did not move. He stood on the damp grass of the clearing, his single eye fixed on the smoking hole in the boulder. The waterfall continued its relentless thundering in the background, but to Danzō, the world had gone deathly silent. The boy standing before him was four years old. He was a Jinchūriki, yes, but he was supposed to be a tool in the middle of his calibration. He was not supposed to be a mirror that reflecated the techniques of a master back at him with perfect fidelity.
"Just how did you do that?" Danzō asked again. His voice was no longer a command. It was a jagged, desperate inquiry.
Naruto wiped a stray drop of sweat from his forehead. His breathing was heavy, but his gaze remained as sharp as a razor. "I just copied what you did, Lord Danzō. I watched the way the heat manifested. I watched the way you used the wind to contain it. I simply repeated the sequence."
"That is impossible!" Danzō's shout was a sudden crack in his composure. The guard behind him flinched, but Naruto did not move.
Danzō knew the mechanics of ninjutsu better than almost anyone in the Hidden Leaf. To copy a jutsu of that caliber was not a matter of simply seeing hand signs. A shinobi had to understand the nature transformation involved. They had to mold their chakra into a specific spiritual frequency that matched the element. Even the Uchiha, with their legendary Sharingan, could only copy what their bodies were capable of producing. For a child with an affinity for Wind and Earth to suddenly produce a high-level, personalized Fire Style jutsu after seeing it once was a violation of the natural order. It suggested a level of chakra control that transcended the human limit. It suggested that Naruto wasn't just learning; he was rewriting himself on the fly.
Danzō took a deep breath, his knuckles white as he gripped his cane. His mind raced through the possibilities. 'Was it the Fox? No, the Fox's chakra was chaotic and destructive; it did not lend itself to this kind of surgical precision. '
'Was it the boy's heritage? The Uzumaki were known for their vitality, not for this kind of frighteningly cold genius.'
"If you truly possess the ability to mirror the world," Danzō said, his voice dropping into a low, dangerous tone, "then try to copy this. This is not a technique for children. It is not a trick of the light."
Danzō moved away from the water's edge and stepped into the center of the clearing. He began a sequence of hand seals. It was not the fast, fluid motion he had used for the fire. These seals were deliberate, heavy, and incredibly complex. His fingers twisted into shapes that Naruto had only seen in the most restricted scrolls of the library. The air in the clearing began to grow heavy, the atmospheric pressure rising until the sound of the waterfall seemed muffled.
Snake. Dragon. Ox. Tiger. Bird. The sequence went on and on. It was a chain of over forty seals, each one demanding a massive surge of chakra.
Naruto watched with wide eyes. In the manga and anime, he had seen Danzō as a man of political intrigue and hidden blades, someone who relied on the Izanagi and Shisui's eye to survive. But here, in the flesh, the man was a powerhouse. This was a Danzō who had survived the First Great Shinobi War, a man who had trained under the Second Hokage himself. The sheer volume of chakra pouring out of the old man was staggering. It felt like a mountain was being moved.
"Earth Style: Pillars of the Obsidian Void!" Danzō roared.
He slammed his palms onto the ground. The earth didn't just shake; it groaned. Massive, jagged pillars of black purple glass erupted from the center of the clearing, shooting fifty feet into the air. It wasn't just stones. It was obsidian, created by the intense pressure and heat Danzō had forced into the soil. The pillars were surrounded by a swirling vortex of dust and gravity, pulling in nearby rocks and pulverizing them into powder. It was a destructive, S-rank jutsu that consumed an immense amount of chakra, something Danzō rarely used in battle because the casting time was a liability.
The pillars stood as a monument to Danzō's raw power. He pulled his hands back, his chest heaving slightly. His face was pale, the exertion clearly taking a toll on his aged body. He looked at Naruto with a challenge in his eye.
"Can your logic copy the weight of the earth, Zero?"
Naruto didn't answer. He sat down on the grass and closed his eyes.
***
Immediately, he was back on the Observation Deck. The white void surrounded him, and the projection of Danzō was already playing back the forty-four seals.
'I need more time,' Naruto thought. 'This isn't a simple frequency. This is a complex harmony of tectonic vibrations and molecular compression.'
He used the Observation Deck to its fullest to slow the footage down until a single second of real-time became a day of subjective study. He spent a week inside his own mind. He watched the way the Earth chakra was forced into the silicon in the soil. He analyzed the specific vibration required to turn common dirt into purple volcanic glass. He saw the "holes" in Danzō's efficiency, the places where the old man was using raw power to compensate for a lack of perfect geometric alignment.

In the real world, five minutes passed. Danzō stood in the clearing, a cold smile beginning to touch his lips. He watched the boy sit in silence, thinking that the first success had indeed been a fluke. He thought that the boy's mind had finally reached its limit, broken by the sheer complexity of an S-rank technique.
Then, Naruto's eyes snapped open.
He didn't look tired. He looked hungry.
He stood up, his legs shaking slightly from the mental strain, but his hands were steady. He began the seals. They were identical to Danzō's, but there was a subtle difference in the rhythm. Naruto wasn't just copying the movements; he was correcting the timing. He was using the Vector Harmonization he had learned from the scroll to remove the friction in the chakra pathway.
Forty-four seals. Naruto finished them in half the time it had taken Danzō.
He slammed his small, pale hands onto the dirt.
The ground didn't just groan. It screamed.
Pillars of obsidian erupted from the earth, but it wasn't jagged like Danzō's. It was a perfect, faceted spires of purple black glass that glowed with a faint, silver internal light. It was taller, sharper, and the gravitational vortex around it was so focused that it created a localized vacuum, drawing the mist from the waterfall toward it in a swirling spiral.
Naruto held the connection for three seconds before his chakra reserves hit the red line. He pulled his hands back and slumped to one knee, his lungs burning as he gasped for air. The silver light in his eyes faded, leaving him looking small and exhausted.
The clearing was silent again, save for the crackling of the cooling obsidian.
Danzō looked at the pillars. His own was a rough, brutal weapon. Naruto's was a masterwork of structural engineering. The boy had not only copied the jutsu; he had optimized it. He had found a way to achieve a more devastating result with less wasted energy.
"Just what are you?" Danzō asked. His voice was no longer a whisper. It was a gasp of pure, unadulterated shock. He looked at the four-year-old child as if he were looking at an alien being that had descended from the stars.
Naruto stayed on his knee, his head bowed. "I... I don't have enough chakra to do that again," he admitted, his voice thin. "The S-rank techniques are too taxing for this vessel. I can see the path, but the bridge is still too narrow."
He looked up at Danzō, his expression unreadable. "Lord Danzō, I cannot master the world if I am dead from exhaustion. Teach me your specialties. The Wind. The blades. Teach me the things that don't require the strength of a mountain, but the sharpness of a breath."
Danzō was silent for a very long moment. He looked at the obsidian spires, then at the boy, and then at the sky. A dark, slow smile began to creep across his face. It wasn't the smile of a teacher, but the smile of a man who had just won a war he hadn't even started yet.
'He is my disciple,' Danzō thought. 'He is the ultimate weapon, and he is mine. I have the Cursed Tongue Root Seal on him. I have his loyalty. I have his body. The more powerful he becomes, the more the Foundation grows. I will have the strongest shinobi in the history of the world under my thumb. With a tool like this, the Third Hokage's softness will be a memory. I will carve the future of the Leaf with this boy's hands.'
Danzō didn't know that the seal was a ghost, a remnant that Naruto's silver marrow had already isolated and bypassed. He didn't know that the "loyalty" he saw was a calculated performance by a man who had already lived and died once. He only saw the masterpiece he was building.
"Very well," Danzō said, his voice regaining its cold authority. "We will set aside the great elements for now. You have shown me that your mind is ready. Now, we will sharpen the blade."
They spent the next few hours in the clearing as the sun began to dip toward the horizon. Danzō taught him the secrets of the Vacuum Style. He showed Naruto how to infuse wind chakra into a simple shuriken, turning a piece of cheap metal into a whirling saw that could cut through solid oak. He showed him how to extend a blade of wind from a kunai, creating an invisible sword that was sharper than any steel.
Naruto soaked it up like a sponge. He didn't need the Observation Deck for these. The principles of Wind were already a part of him. He felt the silver chakra dancing at the edge of his fingers, extending and contracting with the ease of a physical limb.
By the time night fell over the forest, the clearing was a graveyard of sliced trees and shattered stones. Naruto was exhausted, his clothes damp with sweat and his muscles aching with a fatigue that reached into his very bones. But he remained on his feet. He stood in the center of the clearing, a kunai in his hand, the edge of the blade shimmering with a faint, deadly hum.
Danzō stood a few feet away, watching the boy in the twilight. He felt a sense of satisfaction that he hadn't felt in decades. He had spent his life trying to protect the Leaf from the shadows, using every dirty trick and every cold-blooded sacrifice he could find. But now, he had something better than a trick. He had a god in training.
"The lesson is over for today, Zero," Danzō said, turning back toward the forest path.
Naruto didn't reply. He just let the wind blade dissipate and tucked the kunai back into his holster.
As they walked back through the dark woods toward the hidden hatch of the Foundation, Danzō glanced back at the boy trailing behind him. He saw a useful tool, a perfect weapon that would one day rule the shinobi world in his name.
Naruto, meanwhile, looked at the back of the old man's head and thought about the other five scrolls. He thought about the Observation Deck and the Prime Frequency. He knew that Danzō thought he was the master.
And as long as Danzō thought that, Naruto would have all the time in the world to finish the architecture of his own freedom.
