Behind the Senju Old House, sunlight filters through the dense forest, dappling the grass.
"Whoosh! Whoosh! Whoosh!"
Several palm-sized, high-quality Konoha standard Shuriken drew graceful silver arcs in the air.
"Take it! Take it! Take it!"
Three Shuriken were firmly embedded in the bullseye of an old tree stump dozens of meters away.
It hit the bullseye perfectly, half an inch deep.
However, Naruto Uzumaki, standing still, looked at his masterpiece without a trace of excitement on his face.
Instead, he puffed out his cheeks with obvious disgust, shaking his head and sighing repeatedly.
"No... it's too light, too soft!"
Naruto stepped forward, casually plucked the three small metal pieces from the tree bark, and tossed them in his palm:
"At the Ninja Academy, Iruka-sensei Tenten taught us every day to pay attention to the arc of our wrist movements, calculate wind direction, and fine-tune the angle using Chakra Threads."
Naruto grabbed his golden spiky hair in frustration.
"Even if you hit it perfectly, it wouldn't even be good enough to tickle a monster like Orochimaru or Shukaku!"
After witnessing firsthand the godlike, demonic punch of the Senju Kenya, I realized...
Naruto's vision and way of thinking have long since transcended the traditional scope of Genin.
In his view, these light, flimsy little darts...
It completely contradicts the "pure and elegant aesthetics of violence" that the older man was talking about!
"Plop, plop."
A series of crisp footsteps, accompanied by a faint scent of tobacco, drifted from the woods.
Senju Kenya shirtless, wearing bright floral shorts and flip-flops, and carrying a large bowl of tempting, bright red braised beef.
He chewed on his white jade pipe while grabbing large chunks of beef and stuffing them into his mouth, his mouth oozing with oil.
As he approached, Kenya looked at the few small metal pieces in Naruto's hand.
Thump!
Kenya raised his white jade pipe and, without any hesitation, smashed it onto Naruto's forehead, instantly creating a small bump.
"Hey little blondie, I've been seeing you flying around here with those little metal pieces since early this morning."
Are you trimming tree bark or picking at mosquitoes?
Naruto rubbed his reddened forehead, looking aggrieved as he raised the Shuriken in his hand:
"Uncle! I'm practicing Konoha-Style Shurikenjutsu!"
"But I always feel that this move is too weak; it can't kill anyone at all!"
"Nonsense!"
Kenya rolled his eyes, swallowed the beef in his mouth, and began his invincible lecture on physics deception:
"Those old geezers at the Ninja Academy only teach fancy tricks!"
"What arc, what rotation? It's all a bunch of fallacies and crooked tricks that miss the point!"
Kenya crouched down and patted Naruto's head:
"I'm going to teach you a big lesson today, so remember it well!"
"What is the true destructive power of projectile weapons? It's kinetic energy!"
Kenya gestured roughly with his hands, spitting as he spoke:
Kinetic energy equals half the mass multiplied by the square of the velocity!
"Your little piece of metal only weighs two ounces. Even if you throw it with all your might, no matter how fast it goes, the kinetic energy will only be enough to tickle someone!"
Kenya's lips curled into a wild and domineering grin:
"As long as what you throw is heavy enough!"
"Don't even mention Shuriken, you could throw a two-hundred-pound iron block!"
"If it's fast enough, whoever gets hit in the face will have their head blown to bits on the spot!!"
Listening to this groundbreaking, yet extremely hardcore, theory of physics.
Naruto's previously bewildered face suddenly lit up with two bright blue eyes that shone like two little suns!
"Big enough... it'll blow up into a rotten watermelon on the spot?!"
Naruto was so excited that he trembled all over, feeling as if a brand new path to heaven had been pushed open before his eyes!
"Bai! Bring over the training toys we customized for this brat!"
Kenya shouted towards the depths of the forest path.
A moment later.
Wearing a white apron with a floral pattern, she slowly walked over, pushing a heavy-duty flatbed cart made entirely of black iron.
The moment the cover on the cart was suddenly ripped off.
"Boom!"
A cold, heavy, and even pungent smell of heavy industrial engine oil filled the air with a murderous aura!
Naruto looked down and gasped in shock!
On the cart, dozens of enormous objects with extremely exaggerated shapes were neatly stacked!
That is indeed the shape of a four-cornered Shuriken.
But this thing is a full meter and a half in diameter!
The entire piece was forged from solid Black Iron Wood melted and Chakra iron using the highest density materials in the Iron Fist Heavy Industries!
It was three inches thick, and every Kakuzu had a blood groove as sharp and cold as a horse-slaying sword!
Each one weighs a whopping eighty pounds!
"This... this is Shuriken?!" Naruto swallowed hard, his eyes nearly popping out of their sockets.
That's clearly a spare tire for a heavy truck!
"Stop talking nonsense and watch carefully!"
Kenya casually handed the bowl of beef in his hand to Shiro.
He walked to the cart, casually hooked it with one hand, and the solid black iron Shuriken weighing eighty pounds was lightly held in his fingertip.
Kenya stepped forward, without even aiming.
He didn't even use a single bit of Chakra!
In an instant, the muscles in his right arm bulged up like a hill!
A pure, bizarre power surged violently from the point where the waist and horse were in perfect harmony!
"Get the hell out of here!!"
With a single swing of his arm, Kenya hurled the enormous black Shuriken as if it were a pebble with brute force beyond reason!
"BOOM--!!!"
A terrifying sonic boom, like the firing of an anti-aircraft gun, instantly tore apart the entire dense forest behind the mountain!
The eighty-pound black iron Shuriken broke the sound barrier the moment it left the hand, creating a visible, violent white vacuum storm!
"Boom!!"
A kilometer away, there was a small hill, tens of meters high, that was originally intended to serve as a backdrop.
In the instant that black iron Shuriken pierced through the air.
They couldn't even withstand it for half a second!
The entire mountain was instantly flattened and blasted apart by the terrifying kinetic energy, turning into a raging torrent of debris!
Amidst the billowing dust, the black iron Shuriken, its power undiminished, plunged deep into the earth's vein rift, leaving behind a bottomless abyss!
The entire venue was deathly silent.
Naruto stared wide-eyed at the mountain that had been physically flattened.
At this moment, the Uzumaki Bloodline and Nine-Tails Chakra within his entire body completely boiled and burned wildly!
"That's what you call throwing Shuriken?!"
Naruto roared, his arms bare, and charged at the cart with a howl!
The veins on his hands bulged, and the vast, boundless life force within him poured into his arms without reservation!
Encouraged by Kenya's loving words, "If you can't break five mountains in ten minutes, I'll throw you as Shuriken."
Naruto gritted his teeth, picked up an eighty-pound black iron Shuriken, and with an almost insane, savage motion, flung it wildly with a violent whistling wind!
"Boom! Boom! Boom!"
The rocks and giant trees on the entire back mountain began to explode and collapse one after another in a series of horrific explosions!
And at this very moment.
Kakashi Hatake happened to be passing by with Sakura Haruno on their way to carry out a routine mission.
Watching the truck tires, Shuriken, hurtling through the sky and smashing the earth into huge craters.
Kakashi's Forehead Protector nearly fell to the ground in fright, his dead fish eyes widening completely!
Meanwhile, deep in the shadowy shade of the trees nearby.
Sasuke Uchiha tightly against the old tree.
