Naruto's expanded awareness detected them immediately—countless particles suspended in the air around him. Not just oxygen and nitrogen molecules, but something else. Something energetic. Vital. Potent.
Natural Energy. The breath of the planet. The fundamental essence permeating all existence, flowing through the earth like blood through veins.
[When you sense them,] the System instructed gently, [absorb them. Draw them into your body. Refine them according to the Nature Attunement you've just learned.]
Without needing further prompting, Naruto began the process.
Following the technique precisely, he opened his awareness fully. His unified consciousness—spirit, energy, and body working in perfect harmony—reached outward. Not with hands, not with chakra, but with intention itself.
The Natural Energy responded.
They drifted toward him like moths drawn to flame, like iron filings pulled by magnetism. Entered his body through pores, through breath, through the subtle boundaries where flesh met air.
Once inside, Naruto's internal energy caught them, refined them, transformed raw environmental essence into something his body could utilize. The process was instinctive despite being new—like breathing or swallowing, natural once you understood the mechanism.
An hour passed in what felt like minutes. Naruto remained motionless on his boulder, wings of energy flowing into him constantly, being processed and integrated. The golden mark on his fist grew incrementally darker with each cycle.
Then he stopped.
Not because he'd reached some natural conclusion, but because something more important demanded his attention.
Now that spirit, energy, and body are unified, Naruto thought, his internal clarity absolute, it's time to visit Sarutobi Hiruzen.
Time to "make friends."
The decision carried weight. Finality. This wasn't impulsive anger or temporary rage. This was calculated intention born from years of accumulated grievances and recent revelations.
Originally, Naruto had planned to "make friends" with both Hiruzen and Danzo. To go through his standard process with both village leaders, establishing his dominance through the same method that had worked with Orochimaru, Zabuza, and countless others.
But learning from Orochimaru that his parents' remains were being desecrated—that Danzo's Root organization was conducting research on Minato and Kushina's corpses, treating them like laboratory specimens—had changed everything.
That kind of person doesn't deserve friendship, Naruto decided coldly. That kind of person should be killed with a single punch.
No process. No opportunity for redemption. Just immediate, absolute termination.
The distinction was important. Naruto still believed in his philosophy—that strength created the foundation for genuine relationships. But there were lines. Boundaries that, once crossed, removed someone from the category of potential friend and placed them firmly in the category of enemy requiring elimination.
Desecrating his parents' bodies crossed that line.
After stopping the Natural Energy absorption, Naruto examined his right fist again. The golden mark had definitely darkened, become more defined. And when he activated his Iron Body technique slightly, channeling energy through his transformed physiology, the mark emitted a faint golden glow.
If I condensed all twelve golden marks across my entire body, Naruto realized, and then activated the full Indestructible Golden Body technique, I would shine like the sun. Radiate golden light so bright it would be blinding.
The mental image was both impressive and slightly embarrassing.
Unity of spirit, energy, and body had elevated everything. His strength exceeded previous levels by orders of magnitude. His control over his physical form had reached truly terrifying precision. He could sense and manipulate individual muscle fibers, could redirect blood flow consciously, could command his body with the same ease most people commanded their hands.
More importantly, he'd achieved harmony with heaven and earth. Could affect and control magnetic fields within certain ranges. Could interact with the environment itself as an extension of his being.
Which means, Naruto thought with growing excitement, my Heavenly Steps technique can truly step on the sky now. Not just moving across ground at incredible speed, but actual flight. Walking on air. Ascending without limit.
Flying. Across all human history, across all cultures and peoples, the dream of flight remained constant. The desire to soar above earthly constraints, to move through three-dimensional space with perfect freedom.
And now Naruto possessed that capability.
However, before testing aerial movement, before pushing his new abilities to their limits, Naruto wanted to examine something else first. Something more immediate.
How precise is my body control now? he wondered. What can I actually accomplish with this level of mastery?
The question connected to a memory—the Uchiha massacre, when he'd rushed to help Sasuke. During the brief confrontation with Itachi, Naruto had managed to strike the elder Uchiha brother in the back.
At that moment, with his previous level of control, Naruto had only been able to command his back muscles to contract and extend with particular force. Could only channel power through specific muscle groups, creating impact that caused damage but couldn't precisely target vital areas.
It was an excellent opportunity, Naruto recalled with frustration. A clean hit on an opponent who wasn't defending. But I couldn't kill him with that blow. Couldn't direct the force precisely enough to rupture organs or sever the spine.
The control wasn't sufficient.
So now, with unity achieved, Naruto wanted to test his limits. See exactly how far his bodily mastery extended.
Closing his eyes, Naruto directed his awareness inward. Felt every structure, every system, every component of his physical form. Then he began experimenting with movement, with transformation, with shapes his body could assume.
On Naruto's back, the two large latissimus dorsi muscles suddenly contracted in unusual patterns. Not the normal expansion and relaxation of standard movement, but something more controlled. More deliberate.
The muscle tissue began extending. Growing. Protruding outward from his back in sharp, defined points. Like spikes emerging from beneath the skin, lengthening steadily.
Five centimeters. Ten. Fifteen. Twenty.
The spikes stopped at twenty centimeters—roughly eight inches—standing out from Naruto's back like natural weapons. Like the quills of a porcupine, but made of muscle tissue compressed and shaped through pure will.
This is controlling back muscles and changing their form, Naruto marveled. Transforming soft tissue into rigid structures through density manipulation and shape alteration.
With his physical strength, with the density his Iron Body training had granted his flesh, these muscle-formed spikes were no less durable than the Kusanagi sword Sasuke currently wielded. If someone attacked Naruto from behind now, if he leaned backward against an assailant, the spikes would definitely penetrate.
Impale. Kill. Protect automatically.
The two back spikes were just the beginning.
Taking a deep breath, cycling his energy, Naruto began forming more projections. Spikes emerged across his chest, his shoulders, his arms. Down his sides, across his abdomen. Every major muscle group participated, transforming portions of themselves into defensive weapons.
Even his legs weren't exempt. The tough fabric of his mysteriously durable pants stretched and deformed as flesh spikes pushed through, protruding like thorns on rose stems. The pants themselves showed remarkable resilience—battle damage had never destroyed them, and even this transformation only created small tears rather than complete failure.
What are these things made of? Naruto wondered absently. I really need to find out so I can mass-produce them.
Within minutes, Naruto resembled a human hedgehog. Flesh thorns covered his body in overlapping arrays, creating a defensive barrier that would punish any attacker attempting close combat.
These weren't soft protrusions either. Each spike possessed hardness comparable to steel, rigidity that would pierce armor and flesh with equal ease.
Looking at the flesh thorns extending from his hand, Naruto decided to test their penetrating power properly. He drew his elbow back, positioned one of the thorns protruding from that joint carefully, then slammed forward.
The elbow spike struck the massive boulder beneath his feet—the same rock he'd been training on for days.
The thorn sank into solid stone instantly. Submerged completely, disappearing up to Naruto's elbow joint. When he pulled back and raised his arm, examining the impact site, he found a deep cavity had formed. Small but profound, like a honeycomb cell carved into the rock's surface.
"Perfect," Naruto breathed, satisfaction warming his chest. "This level of muscle control is amazing."
He activated his vibration technique next, channeling high-frequency oscillations through all the spikes simultaneously. They trembled, creating a whirring sound that filled the air. Like a thousand tuning forks all vibrating at slightly different frequencies.
The noise was actually intimidating. Combined with the visual of spikes covering his body, the auditory assault added psychological impact to physical threat.
[Wonderful,] the System's voice manifested with approval. [A perfectly weaponized human form. For practitioners of your path, your body IS the most perfect weapon. Nothing external can match what you've built internally.]
The System paused, then added something important.
[Naruto, you can also control your bones. Not just superficial muscles. Your skeletal structure responds to unified consciousness just as readily as soft tissue does.]
"You're right," Naruto agreed, his mind already racing toward implications.
He stopped the vibration, ceased the whirring sound. Simultaneously, all the muscle spikes across his body retracted, flowing back into normal configuration. Within seconds, he appeared human again—no protruding weapons, no obvious modifications.
Then, focusing his intention deeper, Naruto commanded his bones to extend.
Two bone spurs erupted from his back, tearing through the muscle layer with sudden violence. No pain registered—his control was too precise, his awareness too complete for something as mundane as pain signals to override intentional action.
The bone spurs rose like towers being constructed at time-lapse speed. One meter. Two. Five. Ten.
They stopped at ten meters—roughly thirty-three feet—standing out from Naruto's back like enormous flagpoles. But they didn't remain simple spikes.
Following his mental commands, following the image he held in his consciousness, the bone structures began branching. Smaller protrusions extended from the main spars, creating frameworks. Ribs. Struts. Support structures.
Within moments, a pair of skeletal wings had formed.
The bones alone would have been insufficient for flight—too rigid, too heavy, lacking the necessary surface area. But Naruto's muscles responded immediately to the structural foundation.
Like fluid poured into molds, muscle tissue flowed across the bone wings. Covered them completely, filled in gaps, created continuous surfaces. The transformation completed almost instantaneously.
A pair of ten-meter wings now extended from Naruto's back. Fully formed, functional, integrated into his body as if they'd been present from birth.
Naruto smiled, genuine delight brightening his features.
Let's see if these actually work for flight, he thought. Time to test whether I can truly fly.
The wings felt natural despite being completely new. His spirit, energy, and body unity meant these extensions integrated seamlessly. No awkwardness, no learning curve—they responded to his will as easily as his original limbs.
The wings flapped once. Slowly, powerfully, displacing enormous volumes of air.
Wind exploded outward from the waterfall, disturbing the pool's surface, bending nearby trees. And Naruto's feet lifted off the boulder.
He rose. Gradually, smoothly, ascending with controlled precision. The sensation was extraordinary—like walking upward on invisible stairs, each wing beat carrying him higher.
"It works," Naruto said aloud, wonder coloring his voice. "I can actually fly like this. But I wonder how far? How high? What are my limits?"
The questions demanded answers through experimentation.
Naruto mobilized his full strength, channeling power through his enhanced physiology. The wings beat faster, harder, with explosive force.
WHOOSH!
Naruto's figure vanished from the waterfall in a blink. One moment standing in midair above the pool, the next moment gone—accelerated to supersonic velocity instantly, leaving only disturbed air and echoing thunder in his wake.
He shot skyward like a missile, like a meteor traveling in reverse. The ground shrank below him with terrifying speed. Trees became dots, buildings became toys, the entire farm complex reduced to a miniature model.
Within seconds, Naruto had climbed so high that ground details became nearly invisible. He could make out general geography—forests, clearings, the village in the distance—but individual features had disappeared into abstraction.
He stopped his ascent, hovering among the clouds. Thin wisps of water vapor drifted past his face, cold and damp. The air was noticeably thinner up here, though not yet dangerously so.
"With my strength," Naruto calculated, looking upward toward the infinite blue, "I could probably fly out of the atmosphere entirely. Reach space. But there's no air there. I'd die from oxygen deprivation."
The limitation was frustrating but undeniable. His physical enhancements didn't include the ability to survive vacuum. Not yet, anyway.
Maybe at higher training levels, he mused. But for now, the atmosphere is my ceiling.
"Let's not worry about that right now," Naruto decided, turning his attention groundward. "The most important thing is making friends first. Establishing the proper order of operations."
He began descending, wings adjusting for controlled descent rather than freefall.
"The question is: Sarutobi Hiruzen or Danzo? Who do I visit first?"
Naruto flew slowly toward the farm below, thinking carefully about sequence and strategy. His mind worked with crystalline clarity, weighing options, considering implications.
By the time he reached the airspace above his breeding farm, cruising perhaps two hundred meters up, the decision had solidified.
Courtesy before military force, Naruto reasoned. Making friends with Sarutobi Hiruzen is courtesy—giving him a chance to explain, to make amends, to demonstrate he deserves to live.
Killing Danzo is the military force—the demonstration that betrayal and desecration carry terminal consequences.
The logic was clear. The order obvious.
So I'll make friends with Sarutobi Hiruzen first, Naruto concluded. Then kill Danzo.
Wait. No. That wasn't right.
Naruto's thoughts caught on the phrasing, recognizing an error. He'd meant to think "kill Danzo after befriending Hiruzen" but it had come out backward in his internal monologue.
Actually, let me reconsider the order, he thought more carefully. Visit Hiruzen first, go through the friendship process. THEN, afterward, kill Danzo. Not the reverse.
The distinction mattered. Precision of thought led to precision of action.
On the ground below, Sasuke stood in the farm's main yard, having just finished a late breakfast he'd cooked himself. Nine-Tails had refused to prepare anything, so Sasuke had managed—poorly—to make rice and eggs.
I really need to learn proper cooking, Sasuke thought, grimacing at the memory of burnt rice and rubbery eggs. This is pathetic.
Then something caught his eye. Movement in the sky. A dark shape descending.
"Nine-Tails!" Sasuke called out, his voice sharp with alertness. "Look! There's a bird in the sky!"
The fox's ears perked up immediately. He'd been inspecting the sheep pasture but abandoned that task to scan the heavens.
Following Sasuke's pointing finger, Nine-Tails located the shape. Large. Dark. Approaching steadily.
It's pretty far away but I can still see a big black shadow, Nine-Tails thought. If it's that visible from this distance, up close it must be enormous.
An idea sparked in the fox's mind, practical and food-focused.
Maybe we should catch it for Naruto? Big bird like that could supplement his diet. Might be nutritious.
Other farm residents noticed the commotion. Shikamaru looked up from his breeding records. Zabuza paused mid-shovel, squinting skyward. Haku set down the bucket of animal feed he'd been carrying. Orochimaru's attention snapped upward with scientific curiosity.
All of them focused on the approaching shape.
"Wait," Orochimaru said suddenly, his enhanced vision resolving more detail than the others could see. "That's not a bird. That's a person. A birdman!"
His voice carried shock, genuine surprise breaking through his usually controlled demeanor.
"Birdman?" Sasuke repeated, his hand moving automatically toward the weapons pouch on his hip. "Flying toward the farm?"
Shikamaru's tactical mind engaged immediately. "Prepare to shoot it down. If something's attacking the farm, we defend. No questions."
The group tensed, preparing their respective combat capabilities. Sasuke's hands moved through preliminary seals for Fire Style techniques. Orochimaru readied serpent summons. Zabuza gripped his executioner's blade. Even Nine-Tails gathered chakra, ready to contribute.
The flying figure accelerated suddenly, covering the remaining distance in a blur of speed.
Wind pressure hit them like a physical slap, forcing everyone to brace. The "birdman" had arrived, hovering perhaps twenty meters overhead.
"Fire Style: Fireball Jutsu!" Sasuke's hands completed the seals, preparing to launch.
"Water Style: Water Dragon Bullet!" Zabuza's technique activated simultaneously.
"Hidden Shadow Snake Hands!" Orochimaru's sleeves erupted with summoned serpents.
Three attacks, all aimed at the airborne intruder, all prepared to fire within the next second.
"STOP!" The figure's voice rang out, familiar and urgent. "Stop it! It's me!"
Naruto dropped from the sky, landing with a heavy thud that cracked the ground beneath his feet. His enormous wings folded protectively around his body.
"Don't attack!" he shouted again. "I'm not an enemy!"
"Wait, is that Naruto?" Sasuke squinted, recognition dawning. "But you look like a birdman!"
Hearing Naruto's voice clearly now, all three attackers halted their techniques. Chakra dissipated harmlessly. Summoned snakes retreated back into Orochimaru's sleeves.
They stared at the figure standing before them. Definitely Naruto—same blonde hair, same whisker marks, same face. But with massive wings extending from his back, each one easily ten meters from root to tip.
Naruto looked at his assembled friends and employees, speechless for several long moments.
They almost attacked me, he thought with bemusement. My own people. Nearly blasted me out of the sky.
The wings retracted then, folding inward with fluid grace. The bone structures compressed, shortened, withdrew. The muscle tissue flowed back into normal configuration. Within seconds, the wings had disappeared entirely, leaving Naruto's back smooth and unmarked.
Normal human appearance restored.
"Naruto," Sasuke asked slowly, still processing what he'd witnessed, "why did you become like that just now? What was that transformation?"
"It's a skill from my training method," Naruto replied simply, as if sprouting functional wings was the most natural thing in the world. "Body control. Bone and muscle manipulation. I can form various structures depending on what's needed."
Hearing that explanation—that it was just another application of Naruto's Ultimate Taijutsu—everyone's confusion evaporated immediately.
Of course it's his training method, they thought collectively. Naruto can do anything. This shouldn't even be surprising anymore.
With Naruto, the impossible had become routine. Flight through bone wings? Sure. Why not. Add it to the list of absurd capabilities.
