'Now, ningen, push all the chakra you can into your technique.'

Naruto nodded and focused." Yes Kyuubi-sensei."

"Tajuu Kage bunshin no jutsu!"

One large poof of smoke later and 400 Naruto's could be seen in the clearing. The originals visions grayed and unfocused for a moment, then cleared. Naruto collapsed, the meager weight of his body too much for his now chakra-deprived body.

"Kyuubi sensei, I don't understand why you told me to do this."

'. …the great fox paused, like it was waiting for something, then, the demon chuckled.'

Naruto, slightly frustrated," I don't see what's so funny here sens-ACK!" His speech was cut off as every muscle in his body clenched, the burning that he had experienced earlier in his youki tolerance training was back. "What's going on sensei the bewildered Naruto asked?"

'I'm giving you another surge of my youki to jumpstart any latent, lingering, or leftover youki you have in you that your body hasn't had the time to assimilate yet, I won't normally be able to do this, but since your body is nearly depleted of chakra, none of it will be getting in the way, hindering my youki.'

(Kind of like when Naruto fought Neji in the chunnin exams after all his tenketsu were closed)

It felt like Naruto's body was on fire. It started with an itching, than a scratching, then a steady heat, and finally a burning.

'Now, brat, push all the youki you have in you into another of those Justus.'

"But sensei, I don't know how to mould youki a panicked Naruto replied, it was hard to think straight with every part of his body, inside and out, on fire."

'Just focus on the burning and mould it as if it was chakra, it's not the proper way, but it will do for now.'

With a pained grin, Naruto knew that if there was one thing he could do right now, it was focus on the burning. With gritted teeth and a growl, Naruto announced his technique to the rest of the observing Naruto's.

Tajuu Kage bunshin no jutsu!

A veritable cloud of smoke, at least ten times bigger than the first poofed into existence, and four thousand new clones surrounded the clearing and filled it.

'As you can see, child, using youki in Justus has a different affect. In ninjutsu, it makes the technique much stronger, but, like everything else in this world, it has a drawback. Using youki in ninjutsu makes it much harder to control, single-seal, maybe double at the max, can be used. But anything more than that and it will take years of practice, which fortunately, you have at your fingertips, literally.' The Kyuubi chuckled, amused at its own joke, while Naruto was dumbfounded.

'Now, before you start any training exercises, I want to show another reason why I wanted you to learn this technique, at the count of three, I want you to tell all your clones to unleash as much KI as they can, without a focus, tell them to just emit as much as they can.'

Naruto nodded and repeated the instructions to his clones." On the count of one, two, THREE!" Every clone got an angry look on their face, and Naruto was glad you couldn't feel your own KI, because right than, squirrels started dropping out of trees, birds dropped out of the air, some flowers even wilted. As nearly all the surrounding wild-life died, Naruto was amazed.

'Just like if you had one hundred clones and it would roughly multiply your training by said amount of clones, it does the same with KI. One hundred different sources of KI, but each identical, merging with each other to form a monstrosity of killing intent. As you get better, and hone your skills, it won't be just the wild-life's hearts literally burst with terror; still you are nowhere near that level yet, so begin the exercises I told you to do.'

Naruto cleared his head and ordered all forty-four hundred clones to work on his chakra control, stripping two nearby trees for their leaves, as Naruto rested and attempted to regain what little energy he had left. About an hour later, doing as he was told, Naruto told one hundred of his clones to dispel, in order to distribute experience to himself and the remaining clones, thanks to the warning from Kyuubi, in five batches of twenty.

Naruto did it that one more time, and after that he could do the exercise instinctually. He suspected he would have been able to do it much faster if it wasn't for his naturally massive chakra stores, augmented further by being a jinchuriki, and further after that by his youki tolerance training.

Naruto cocked his head as something occurred to him." Hey Kyuubi sensei, how do you know how to do any of this anyways?"

'Humph, I was waiting for that to come up. Well, thousands of years ago, when the way of the shinobi was only a few hundred years old, I may have gotten curious what all ruckus was about and disguised myself as one of you miserable humans, much to my great displeasure, and tried it out. It was actually quite amusing for a few hundred years, but then it became boring, no challenges left and what-not.'

"What was it like back then?"

Naruto didn't get a reply for a while, until Kyuubi answered with a terse, abrupt, 'Different'

Sensing he had hit a sore spot of some kind, Naruto returned to training. Ordering the remaining forty-two hundred clones to begin the tree climbing exercise he laid back down, comfortable amongst the numerous dead bodies of mice, rats, voles, skunks, porcupines, hedgehogs, squirrels, birds, and uncountable insects.

Six hours later, Naruto's clones began the water walking exercise, Naruto laid back, gazing at the darkening sky, almost completely recovered energy-wise, remembering a prior conversation with his demonic teacher.

Flashback

'Naruto, before you begin your effort to learn and master your new technique, I feel I should explain some of what it will be for, and for what ends it will be used. Before you can even attempt to learn to harness my youki, you must perfect your chakra control, and when I say perfect, I mean it. The taijutsu style I have planned for you requires ridiculous control and concentration, which is what this jutsu is for. You see, this is a solid clone technique, which can be used in battle, but are very fragile. However what they lack in physical qualities, they make up in mental. Whatever they learn, you learn, whatever you know, they know, this includes techniques among other things. Understood?'

"Yes Kyuubi-sama." Naruto could barely hold back his excitement, this jutsu sounded perfect.

End Flashback

With the Kyuubi's helpful tips and comments, the water-walking exercise was mastered in just another 6 hours. Meanwhile, Naruto had been going through further youki tolerance training, albeit on a smaller level than last night, his body still needed to recover, and he hadn't boosted his regeneration abilities to that level as of yet. Kyuubi had let on that if the fox had so willed, having a large amount of its youki in his system would have disrupted and harmed his clones, a lesson it had planned on teaching him, but decided on just verbalizing it to him as a reward for the impressive progress he had made today.

'…so remember Naruto, any more of my youki that you can't control in your system, and it will destabilize most human techniques, got it?'

"*pant* yes Kyuubi sensei. Naruto had just finished with another surge, and it felt like his skin could slide right off if he wasn't careful, a very unsettling feeling. This indicated that anymore youki and his chakra network might crash; he discovered he was getting very good at finding the edge, and pushing it as far as possible."

Naruto still had a thousand youki-made clones left, as he had discovered that they lasted much longer than the chakra-charged ones. He decided to order them to infiltrate the library, and get an elementary through high school education. He grinned at the thought of spiting all those that would hold thirst for knowledge back, as it was, he could only read and write, and do basic math. That needed to be fixed.

Sighing, he pulled his aching body and throbbing brain up, and headed to his dump of an apartment. Thankfully he got there without incident a few hours later, and dropped into his bed for a well-deserved night of rest.

The next morning, Naruto woke up with the desired knowledge from the library, plus a few other bits of information, proper grips on kunai and such, the correct method to ninja-jump, as it was called, so as not to blow off your own legs with chakra trying to cross from roof to roof. He grinned, and then frowned after hearing a rumble his stomach had voiced. Grumbling as he got out of bed, prepared the standard water, meat, rice, and now some vegetables. Apparently if he didn't eat his vegetable, he would end up short, and the thought of that made all the termites in his apartment die from the quick flash of anger-induced KI he made sure to quickly suppress.

'You're picking up the knack of what I call Shinokyofu (fear of death). That's good, once you have mastered that to the full extent of your current capabilities, we will move on to another version of KI.'

"Isn't there any way to hurry it up though sensei? Is there some kind of exercise I can do?"

'I have a few ideas, ningen, but for now, just try leaking a very small amount of KI at all times. That might help. But you will know when it's gone as far as it can. Hehehehe, oh yes, you will know.' Something about that laugh made Naruto wary and want to laugh at the same time. 'Oh, well, I guess I'll find out someday', Naruto thought with a shrug.

"What would you like me to do today sensei? Continue with the chakra-control exercises?"

'Yes, today you will try the kunai-balancing, until you can cover every inch of your skin with kunai and water-walk, while getting you reflexes tested by having clones throw objects at you. *muffled demonic snicker*'

Naruto sweat-dropped, "That last one is just for your amusement isn't it?"

'SO WHAT IF IT IS? DON'T FORGET WHO YOU ARE TALKING TO BOY!'

Naruto winced at the mental roar, and reminded himself not to get too casual with the fox, no matter how at ease it sometimes seemed. Heading back to the clearing he was at yesterday took him an hour of tree-hopping, at his teacher's assistance to be far away enough not to be encountered by anyone.

With his increased chakra control, combined with his youki-saturated chakra, he made an even five thousand clones, with barely half the effort he exerted just the other day, making him realize how much chakra he was wasting. H shook his head, gave his clone their orders, and started his physical exercise.

Kyuubi had explained that no matter how much shadow-clone training he did, it wouldn't make a difference if he wasn't fast or strong enough. But, since he was still four, even if his mind wasn't, he would be focused on speed for now, as seriously training his strength at this age would be detrimental to his health and development.

He found one of the many tracks located around Konoha, that was one of the perks of being extremely corrupt, luxury. Taking off at a sprint, using no chakra to enhance his muscles, he didn't stop until his body collapsed. This took twenty minutes, showing how much he had to make up in endurance. Now, pumping chakra into his muscles, he took off twice as fast, and continued like this for six hours. Increasing his speed every twenty minutes, by the end he was practically a blur compared to his previous speed. Still, he suspected it wasn't supposed to be this easy.

"Um, Kyuubi-sensei, did this seem a little easy to you?"

'Well ningen, it seems you have stumbled upon how youki affects taijutsu. Thanks to your chakra being flooded with my youki thanks to your tolerance training, the chakra you pumped into your limbs also came with youki, which makes you faster, stronger, and tougher. The downside is that use for a long duration of time will practically cripple you. Now, it won't be that severe with my youki aiding you and your enhanced regeneration, but it will do quite a bit of damage. The only way to push the time-limit farther and farther off is to build up your muscles, bones, and skins familiarity to youki, which, mind you, will not be pleasant as I'm sure you will find out in a few hours. Through your life you will learn of techniques that open the eight chakra gates, this will be akin to opening four, five, or six, depending on how hard you push yourself. But no matter what, no pain, no gain.'

'Hmmm, well, it can't be close to all the pain this damned village has put me through.'

Naruto shrugged, and then headed back to the clearing to check up on his clones. If the flood of steady knowledge he had been getting the whole day was anything to go by, things were going well. When he got back, the clones were just finishing up senbon-balancing, and were trying to combine all the exercises together. Some were practicing their accuracy, and some were testing reflexes. Once he had gotten their…um, his, attention he told all the clones to try to create chakra cushions. All the clones immediately stated to punch the ground, rocks, and trees, and at once managed to push out some kind of shoddy chakra cushion that barely managed to stop them from getting dispelled. A sure sign his chakra control had greatly improved. He did the quick math, five thousand clones, training for an hour each… around two hundred and eight days. In an hour! Feeling confident his clones could handle themselves without him there to hold their hands, he headed through the forest, making his way back to the village he hated.

A few hours and a full stomach later, he headed back to his clones, which didn't have anything left to do but practice their aim and their KI "blasting" as he had taken to calling it.

When Naruto arrived in the clearing Kyuubi's voice sounded in his head.' Naruto, now that you have completed the exercises I set out for you, we are going to begin your instruction in taijutsu and youki control. Your taijutsu is something called Shapusutoraiku (Sharp Strike). Tell me child, have you heard of the technique you humans call Chakra Scalpel?'

Naruto grinned darkly, "Enlighten me, Kyuubi-sensei."

2 YEARS LATER

Naruto was making his way home from what had become his usual training ground, dashing across the roof tops. He had grown quite a few inches, now at 4'5 (AN: I'm just guessing what usually height is for 6 year olds. Fill in your desired 6 year old height if I'm wrong) with lean muscles, honed from days on end running, sometimes for his life. He wore almost all black, black ninja sandals he stole, to black ninja pants, also stolen. And a black tee with a shinobi coat (picture shino's coat/hoodie except all black). A shinobi was supposed to blend in with the shadows after all; the only thing that stuck out was the crimson fingerless gloves. The only reason they were crimson was because, they would get stained crimson anyways, with all the blood that spilled on them.

The senses he had honed over lifetimes of shadow clone training allowed him to doge the kunai launched at him, with time to spare. Reacting immediately he seal-lessly created 4 shadow clones which immediately took off to surround the area. Stopping on a flat rooftop, he waited, knowing the aggressors would meet him here. Predictably, two chunnin, judging by their vests, jumped to the roof, one to his left and one to his right.

"I suggest you go home, and apologize, right now" Naruto told them icily, he was in no mood to humor some fools wishing to become heroes by killing the village pariah. He started the ninja academy the next morning, and he wanted to get a full night's sleep.

Something you never do is mess with his sleep. Precious, precious sleep.

His eyes narrowed and the previously created shadow clones appeared in pentagon formation with him at the center, surrounding the two chunnin. Each was blasting a massive amount of KI at the ninja, practicingthe Shinokyofu he had gotten so skilled at, who were now trembling, their body shivering involuntarily.

"B-b-brother, are you s-s-sure this was such a g-g-good id-dea."

The brother responded by shoving down the fear that made it an actual effort for him to breathe. "C'mon nii-san! We'll be village heroes, the ones that finally killed the demon. I won't let some little kid scare ME!" Charging towards Naruto, kunai in his right hand, a quick thrust meant for his skull was dodged by Naruto in a quick spin, getting inside the ninja's outthrust arm, his right elbow striking him in the chest, then continuing its path from sternum to the ninjas right shoulder, continuing the spin, Naruto's left hand, fingers straight sliced down from the ninjas neck to hip. Turning around, his back to the frozen ninja, Naruto inspected his nails. Staring at the frozen chunnin that had just watched his brother attack the demon, Naruto didn't pay any heed to the schlick sound as the bolder brothers body slipped apart, the shape of an X going through his torso before it fell completely apart.

Walking calmly up to the frozen brother, Naruto unleashed a quick, strong burst of KI at the frozen, alive brother, making sure he stayed frozen. Chakra scalpels were clearly coming out of each elbow and hand, except they were red in color, thanks to the Kyuubi's youki. Bringing up his hand as he approached the terrified ninja, traumatized beyond belief from just watching his brother die like a fly on the wall, Naruto stated in a dark, angry voice, "I could have been sleeping right now." And slashed his hand across the frozen ninja's throat, as the body collapsed and the head rolled away, Naruto knelt, searching the two brothers of anything of worth, finding nothing, he wiped the bloody tips of his fingers on their clothes and had his clones gather the body parts into a line.

Naruto, one by one, grabbed a body part, and shoved as much youki as he could through it. Melting the flesh, melting any metal, and crisping the clothing and armor to ash. Kicking some ash over the edge of the roof, Naruto sighed and headed home.

He really wanted to go to bed.

I do appreciate the reviews everybody, so thank you all for that. I do have plans for how youki will affect genjutsu (its gonna be awesome!) and fuinjutsu so we will all find that out later. As far as I know, my idea for chakra scalpels mixed with a taijutsu is original, so let me know what you think of it. I decided we had spent enough time on 4 year old Naruto training, so I hope the time skip doesn't bug anyone. If it does, that's too bad. Let me know what you think, and I hope you enjoyed it. By the way, there was some trouble uploading chapter 3 as some people couldnt read it. if this happens i would really appreciate someone letting me know. Peace out
