Inside the subterranean council chamber of the Mist-Veil Sanctuary, three elders sat around a low wooden table.
They weren’t legendary warriors wearing ornate armor; they were scarred, weary survivors wrapped in heavy wool cloaks.
Before them lay the ancestral scrolls of the Kazeshira clan—faded parchment detailing generations of air-sensing techniques and wind manipulation.
Elder Gen, a blind man whose pale forearms were covered in thick, silver scars, reached out and pressed three fingers against Ren’s wrist.
He focused his chakra, scanning the young boy’s nervous system.
“His pathways are damaged,” Gen noted, his voice flat and unreadable.
“You forced your Wind chakra through immature coils during high-stress battles.
You survived, child, but you ran before you learned how to walk.”
Ren kept his head down, maintaining a quiet demeanor.
“I used what I had to reach the valley.”
“And you paid a price,” Gen replied, pulling his hand back.
“Our clan’s sensory skin—the Aero-Dynamic Receptors—is not a weapon of brute force.
It is a tool of efficiency.
You treated it like armor, flooding it with raw chakra.
That is why your body is feverish and your muscles are tearing.”
Gen gestured toward a young clan trainer standing in the corner.
You do not practice offensive Jutsu.
You will learn to sit, breathe, and feel the natural wind without expending a single drop of your own chakra.”
Ren’s mind calculated the long-term benefit instantly.
He’s right, Ren thought.
I was forcing my modern kinetic ideas through brute strength because I was desperate.
If I learn how to passively read the air without burning my chakra, the efficiency of this trait will skyrocket—and it will be safe enough for a child’s body to handle.
For the next two years, Ren’s life in the simulation was stripped of high-stakes battles.
He didn’t slay enemy squads or dodge legendary fireballs.
Day after day, he sat atop the misty sea cliffs of the northern coast, wearing thin clothing in the freezing sea breeze, learning to let his Kazeshira skin naturally interpret the micro-currents of the wind.
He learned to distinguish the subtle pressure difference between an incoming sea bird and a falling leaf, five hundred yards away, without relying on an ounce of chakra.
By age twelve, his physical body had healed, his chakra pathways had widened properly, and his passive sensory skin was fully integrated.
He wasn’t an invincible god.
But his efficiency was unmatched.
Standing on the edge of the cliff, Ren closed his eyes.
A light breeze blew past his face.
Without opening his eyes, he reached out with two fingers and lightly pinched a tiny, falling pine needle straight out of the air—catching it precisely by its tip.
No wasted movement.
No burned chakra, Ren thought, looking down at his hand.
When I take this back to my six-year-old body in Konoha, I won’t need massive chakra reserves to protect myself.
I just need to see the threat before it ever touches me.
Elder Gen walked up behind him, his cane tapping quietly against the stone.
“You have mastered the foundation, Ren.
Now…
the world outside our valley is burning again.
The Uchiha and Senju are gathering their full forces near the Nakano River.”
Ren looked out toward the southern horizon, his blue eyes calm and focused.
“Then it’s time for me to go back.”
