Combat
With two clones forming a gust of wind in their hands, another clone leapt in front of them and quickly the clone duo brought their palms towards the other clone's feet, causing it to instantly disappear in a cloud of smoke.
"Tsk, we die again."
"This is complicated."
"It's my turn" Arriving another clone, he waited for the clone duo to form the gust of wind and took the leap, only to receive the blizzard on the soles of his feet and disappear.
The actual training is simple.
Having succeeded in manifesting the wind, Naruto perfectly remembered an interesting move in his memories and tried to implement it, making his clones try to use the wind to propel another clone to shoot out with great speed.
But seeing the technique and being able to master it are two very different things, and while Naruto can already manifest his wind and give it a sloppy shape, he doesn't manage to control much more than that, causing each of his attempts to end up damaging the clone enough for it to disappear, something that easily tells them that they're still not even remotely close to being able to use the original Naruto without having the risk of shattering his legs.
"It's my turn."
Puff
"Now mine."

With sweat running down his forehead, Inari's face reddened as he made his maximum effort and held his fingers crossed in a cross.
Puff
Looking at the pale and thin Inari that appeared next to him, Naruto chuckled and replied "Not bad, at least he has a face now."
Puff
Making him disappear, Inari fell on his butt while breathing heavily "Th-this is really hard..."
"What you're doing is a technique that is considered somewhat advanced in the academy, it's already great that you can do it with only a few months of training" Smiling while shaking his head, Naruto continued "Training will always be difficult, since when training you seek to constantly surpass yourself thus overcoming your own limitations"
"How's it going?" Approaching with two glasses, Tsunami smiled towards the duo and continued "I brought you lemonade."
Quickly getting up, Inari ran over to his mother and grabbed one of the glasses, then popped it into his mouth and drank it quickly.
"Well, looks like I'll have to make more" Laughing, Tsunami looked at Naruto and asked "Clone?"
"Clone" Nodding, Naruto continued "But the original will be delighted."
"I'll leave it here-"
"Training ends for today" Appearing another Naruto from the forest and interrupting Tsunami, the newly arrived clone looked at the other clone and continued "We made it."
"Finally" Sighing, the clone next to Tsunami took the glass with lemonade and smiled "Looks like no more clones for today, they'll most likely have to drag the original in a few minutes"
"Sigh" Sighing as she nods, Tsunami rubbed her exhausted son's sweaty hair and continued "I'll get the bed ready for you to rest, thanks for the effort today."
Watching as the clones left, Inari turned to his mother excitedly and crossed his fingers while exclaiming "Mom, look at my super hyper secret ninja technique!"
Puff
Looking at Inari's noodle-thin and colorless as a drawing version of Inari, Tsunami laughed "How cool are you sweetie."
"Mn!"

Sipping the lemonade with a refreshing smile and having already dispelled his clones, Naruto licked his lips and closed his eyes, then slowly flowing his chakra and thinking 'Flow slowly... focus on the first point and have only a trickle of chakra flow while slowly holding back the rest...'
With a few minutes of silence, Naruto opened his eyes wide as his muscles visibly bulged, only to jump up and leave a small hole where he was sitting.
"This is... really intoxicating" Despite the muscle pain tormenting his entire body, Naruto looked down at his fists and disappeared from his place quickly, then appeared next to a tree giving it a strong kick.
Boom!
With a loud bang, the thick trunk shattered instantly as the splinters jumped everywhere, and then disappeared from the place and quickly ran to where he left the sword.
Picking up the sword with no difficulty whatsoever, Naruto swung it and began to wave it around while a fierce but happy smile adorned his face.
"Well... I guess I'll be in trouble" Sitting on a thick branch while reading, Kakashi looked up at the source of the noise and instantly noticed Naruto's monstrous speed and obvious strength boost, then looked down again at his book and muttered while shaking his head "How do I explain to the village that I didn't really teach them anything?"
"Not only do I have an Uzumaki gone mad smashing everything in his path with one of the legendary swords" Turning his gaze to the boy passed out on the ground, Kakashi scratched his cheek and muttered "If not I also have an Uchiha training his physique in a beastly way and now learning the 8 inner gates... this generation really will be a monstrosity."
"..." Watching Naruto again, Kakashi stared at him for a few minutes until he saw that finally the sword fell to the ground and along with it, fell Naruto's body totally unconscious "9 minutes... not bad"
***
"Bastard" Rising from the ground with blood pouring out of his mouth, Sasuke's eyes turned crimson and he quickly lunged at Naruto, who quickly stepped back and nimbly removed the weights from his arms.
Instantly losing 50 kilograms of weight, Naruto increased his speed and easily dodged Sasuke's punches, to slightly tilt his body backwards as he dodged a fist and raised his knee sharply
"...!" With trembling eyes as the air rushes out of his body from the blow to his stomach, Sasuke gritted his teeth and forced himself not to fall from lack of strength, only to quickly back up and focus on his chakra.
Instantly feeling the change in atmosphere as those chilling crimson eyes stare at him, Naruto didn't hesitate and opened the first door, then crouched down and began to quickly remove the weights while Sasuke does the same.
"Shouldn't we stop them?" Watching as they always tend to do in their times of boredom, Sakura turned to Kakashi and asked.
"Let them do whatever they want" Without taking his gaze off the book, Kakashi shook his head and continued with disinterest "As long as they don't try to kill each other, it's all good."
Getting back up at the same time, Sasuke began to slowly circle Naruto as Naruto did the same, both staring into each other's eyes as tension filled the air.
Pa!
Disappearing from each other's place, Naruto gritted his teeth at the fist that rattled his brain and recoiled in frustration as he saw Sasuke easily dodge his own, then pounced again and began a long round.
Pa Pa Pa Pa Pa Pa Pa
Seeing nothing but shadows and silhouettes appear and disappear as loud thumping sounds spread around the place, Sakura spoke with concern "It really looks like they want to kill each other."
Looking up, Kakashi had no difficulty to follow the speed of the duo and raised his eyebrows with interest "This is fun."
"Who's winning?" shaking her head knowing that Kakashi won't intervene, Sakura asked.
"The speed of both of them seems to be similar, but Sasuke wins narrowly, and thanks to his eyes, he has all the advantage."
"So will Sasuke win?"
"It's hard to tell" Looking at Sasuke's reddened face and then at Naruto's beaten, but not showing any signs of exhaustion, Kakashi continued "Naruto is the one being overwhelmed, but he's not even remotely close to falling, and unlike Sasuke, it only takes one hit from him to end up knocking him down... that kid's strength is truly monstrous"
"Ugh!" Receiving a hard kick to the stomach, Naruto was propelled backwards violently and rolled on the ground, only to blink for a microsecond and watch a kick head straight for his face from the sky.
Boom
Rolling on the ground as Sasuke's foot shattered the ground, Naruto jumped up and pounced on him.
With a huff, Sasuke leaned his body back slightly and easily dodged the incoming blow to his cheek, then stepped back a foot and spinning quickly, swung hard at Naruto's face.
Boom
Being sent flying several meters, Naruto crashed hard into a tree as his gaze shook from the pain, slowly falling to the ground as he tried to regain the air he lost from the heavy blow to his back.
'After all this...' Gritting his teeth tightly to the point where his gums began to bleed, Naruto looked up at the young man slowly approaching towards him and frustration flooded his mind 'I train 10 times harder than him, bleed 10 times more than him, and have 10 times more chakra than him, but... I still can't beat the Sharingan?'
"It's my victory" Approaching with a slight smile, Sasuke continued "It's no use your strength if you can't touch me."
"Heh" Letting out an angry laugh while shaking his head, Naruto stood up and spat out the blood he had in his mouth, then pounced on Sasuke and started another round of punches again.
"It won't do, you know that" Stepping back nimbly as his gaze easily follows every fist that grazes his face, Sasuke continued "Chakra is your thing, not physical combat."
"You really are annoying" With a vein bulging on his forehead, Naruto suddenly blinked as a pounding headache began to flood his senses, but unwilling to accept defeat, he ignored it with a grimace and continued throwing punches.
"This is it" Seeing the fist pass by his face, Sasuke ducked slightly and raised his body as Naruto's arm passed over his shoulder, forcing him to raise his arm while without wasting any time, he directed his own fist at Naruto's face.
Pa
"Gotcha" Resisting the blow while smiling fiercely despite having his fist on his cheek, Naruto held Sasuke from his clothes and tilted his head back slightly, then lunged forward and headbutted him hard in the forehead.
Pa
Stepping back a few steps while blinking in a daze, Sasuke suddenly saw a fist heading for his nose and with a quick reaction, he cocked his head slightly, being forced to blink in confusion as he saw that not only was the fist he saw on his face nowhere to be seen, but a faint crimson layer covered Naruto's eyes as the real fist slammed hard into his face.
Pa
Being sent flying dozens of meters, Sasuke bounced a few times on the ground and ended up rolling a couple more meters, being completely covered in dust as blood flowed from his mouth.
"Ugh!" gritting his teeth as he felt as if his brain was shaking, Sasuke weakly stood up and turned his gaze towards Naruto who was running towards him, noticing that this time there is no light in his eyes and his speed slowed down noticeably as a pained grimace covered his face.
"Let's get this over with!" despite also not having the strength to hold the door open, Sasuke's eyes suddenly rolled and a second tomoe joined in as he rushed towards Naruto.
"I should have brought something to eat" Watching the whole fight with an interested look, Kakashi casually commented.
"Surely you won't stop them? They look like they're really not in good condition."
"It's okay, it'll be over."
Pa Pa
Seeing how they both ended up hitting each other, Kakashi smiled under his mask and watched in slow motion as they both fell heavily towards the ground while breathing heavily, but this time,running out of strength on the ground.
