~Soutarou POV, Scene Continues~
Soutarou's eyes forced up and his once falling body straightened as his arm barely began glowing in chakra. Allowing him to see again albeit momentarily. He formed a modified ram hand seal with one hand. His sensory technique, rather than expanding, focused on Tsunade's chakra. As he did he began to adjust his chakra flow coating his chakra.
'Dammit. Sensory techniques plus coating my chakra in this active way there's no way I can copy what Tsunade's doing… Her chakra is just drawn out, everything is just instinct. If she even takes one step towards me I'll go flying. Come on, Soutarou! Think. Think! There has to be a way to move forwards… Wait! It's a bit stupid, but what if I use my chakra to propel me forwards like a pseudo body flicker?'
Forming a single handsign and a normal ram sign Soutarou instead of projecting the chakra fully coated himself in the chakra causing him his chakra coat to move down to legs forcing him forwards in robotic steps all the while the pressure then knocked him down. Just as he was about to fall a hand shot out and grabbed him by the scruff of his neck.
Tsunade looked curiously before saying, "Not bad. You figured out how to use chakra coating on one part of your arm, but it's really lacking. Not only that, but your chakra control is poor."
"While that's fine if you just want to reach the level of Second Grandpa and First Grandpa. If you really want to take this taijutsu style to the peak, you have to reinforce every portion of your body all together, even your organs. Once you're able to do that you'll become a force of nature as chakra begins to infuse into your entire body, it'll eventually create a feedback loop, strengthening your body to the point you'll become like me."
"For example, even if I fool around and just drop an axe kick on the ground, I'll create a massive crater without even trying. In terms of strength this is the path beyond even that which the Raikage's can reach. If I really gave it my all and punched I could blow through mountains. The biggest benefit as you can see…"
"If you manage to coat and infuse your entire being with chakra then your chakra reserves will actually increase. There's only two ways to achieve this, through intelligence, a bit of medical knowledge, and hard work or sheer hard work and over exertion like what Might Guy and his father Might Duy do. That however will cut off your path to ninjutsu, as overloading chakra in that manner permanently expands and damages those very chakra pathways."
"That's why most practitioners of the eight inner gates never go beyond the fourth or fifth gate. Anyways no need to worry about those techniques for now. You only need to focus on my path. If you can do this much even if you don't learn any real ninjutsu you'll be able to easily become an elite jonin without much hard work. And if you learn a forbidden or strong killing technique alongside this you'll break into S-rank, similarly without much hard work. As for Kage-Level? That's up for debate, I personally only need this taijutsu and my two forbidden techniques, but I'm not sure if you'll try to take this taijutsu as far as I did."
Tsunade berated Soutarou a bit more about his lacking chakra control and began to show him his errors before ruffling his hair and saying, "Not bad kid. You're almost as talented as me at this."
Soutarou huffed and said, "You really can't just give a proper compliment?"
Tsunade grinned before suddenly flaring her chakra and throwing a punch to which Soutarou instinctively threw his arms up and infused as much chakra as he could into them. Just as Soutarou felt like he was going to die, Tsunade's punch stopped right in front of his arms creating a massive wind pressure causing Soutarou to skid backwards. Tsunade smiled at him and said, "Now if you want I can give you a compliment. If you hadn't properly learned that technique your eyes would've been slashed to bits by the wind pressure."
Soutarou stared at his arms that were bleeding very seriously as he blankly thought, 'If Tsunade is this strong then how strong are the other kage? What about Jiraiya? Just with an unserious punch she can create this much wind pressure and that with her holding back on it too… What the hell. Just.. Just how strong are Madara and Hashirama? Man, the anime really underportrayed just how strong these bastards are…'
Soutarou felt a chill go down his spine as reality hit him like a freight train. Shaking his thoughts Soutarou didn't let his guard down as he could tell Tsunade was of the mind to beat the learning into his bones. And his guess turned out right as Tsunade suddenly seemed to teleport in front of his eyes Soutarou ducked down and used his coating to concentrate on one leg before kicking the ground as hard as he could creating a small crater the caused him to to sink down and made Tsunade fly by the tips of his hair. She grinned at him and then proceeded to jump at him again….
~Three hours later, Soutarou POV~
Laid out flat on the ground, Soutarou struggled to breathe. All around him were massive craters and chunks of jutting rock that were repairing themselves albeit slowly. As Soutarou himself, the brown haired red eyed boy was bruised, his shirt or what was left of it was in tatters exposing black and purple spots all over his chest. Similarly his legs were bruised beyond recognition. While one of his ankles was twisted.
As for his face, Tsunade had ruthlessly turned him into pincushion to smack the shit out of. His lips were a bloody mess, his nose was bent in a weird way actively trickling blood, all the while his cheeks were beyond swollen and purple. As for his eyes, it was hard to see them, though thankfully Tsunade hadn't directly hit him on the top or near the top of his head. Still Soutarou's vision swam as Tsunade had ruthlessly struck his chin and cheeks as if they were punching bags. Worst of all Soutarou knew that Tsunade hadn't even punched with serious force, forget calculating it in percentages she had used less than 0.1% of her force. Soutarou lost himself in his thoughts as his brain seemed jarred before a soft healing glow erupted along his entire body, before a small slug hopped on top of him and began slathering all over him in the most gross manner possible.
Soutarou groaned before Tsunade lightly chopped his head saying, "Stop being a cry baby, how are you supposed to learn if I don't beat your bad habits out of you? Forget that if I don't beat the shit out of you won't be able to learn how to do any of this instinctively. Once your body starts infusing chakra instinctively the beatings will slow down. But until then you have the world's best healer beating the life out of you and don't worry no where I hit will hurt your development, afterall I know several ways to make you painfully suffer without mortal harm, so don't worry you're in safe hands."
Soutarou began to actually cry as he muttered, "Injustice! I demand the Hokage, this old lady is torturin-"
The moment he said old lady Tsunade's hair literally began to flutter in waves of chakra and Soutarou quickly corrected himself saying, "This damn young woman is torturing me all day. Injustice I say!"
Tsunade stared at him without talking before finally saying, "You know I'm going to beat you harder next session, because of that right?"
Soutarou panicked and he said, "I'll give you 100,000ryo as compensation, but you can't hit me harder!"
Tsunade smiled and said, "Oh I'll take the 100,000ryo don't worry, but remember this is for your training. It's for your own good you'll understand one day."
Soutaruo screamed in agony and cursed crazily, "You fucking demon! Damn you should've stayed hemophobic. Dammit I regret helping you! Ungrateful, worthless, piece of shit. I swear the day I'm strong enough to smack the shit out of you I'll tear you to pieces!"
Tsunade smiled and nodded her head saying, "I told Second Grandpa the same thing, unfortunately I never got the opportunity to do so. Thankfully his wonderful grandson is right here for me to do that to."
Soutarou paled and cursed again, "Dammit. Dammit! I don't want this kind of generational trauma, god dammit!"
Tsunade smiled and said, "Don't worry you're a Senju. If you ever get angry just go beat an Uchiha. I hear there's a fairly talented kid your age… I think his name is Itachi Uchiha? Oh there's also Shisui Uchiha, so work hard. Our ancestors didn't die just so you could whine because I'm beating you up to make you strong enough to make any three-tomoe Uchiha piss their pants. You'd better not disappoint me after you talked so big or I swear I'll come back and beat the shit out of you everyday just to get revenge for you smearing your blood all over me. I'll also beat the shit out of you for wasting Grandpa's legacy. So work hard."
Soutarou in his boiling anger literally shot up the moment Tsunade and the slug, Katsuyu, finished healing him. He immediately charged Tsunade infusing chakra into both arms and swinging at her twice, before using her raised arm as a springboard to launch himself above Tsunade and drop an axe kick on shoulder only for a resounding crack to ring out and Soutarou himself almost cried out in pain as he thought, 'What is she made of? Fucking metal? What is this superman bullshit?'
Soutarou pushed off of her using his other leg and his arms clutching his leg with hand he steadied himself before Tsunade suddenly disappeared not only from view, but his passive sensory field. Tsunade's voice rang out across the training field, "Since you've decided to be so proactive… I'll give you a reward. That reward is called combat experience. First tip… When dealing with sensory shinobi, suppress your chakra. They're all too reliant on sensory techniques and not their instincts."
Then Tsunade's leg swept Soutarou's legs out from underneath him suddenly all while Soutarou threw his hand in a back hand motion, giving up on his legs and pushing as much chakra as he could into his hands… and so repeated the earlier portion of the day.
Ending with Soutarou passing out and finding himself in his bath soaking in his reinforcement bath he panicked for a moment before Tsunade, who was sitting on the bathroom sink countertop looked at him with a grin and said, "Had fun today?"
Soutarou said, "How did you open that drawer?"
Tsunade waved her hand and said, "I didn't take it off your body, the key I mean I just craned you over and used you as the key to unlock the door and then the cabinet. Plus I needed to actually make the compound one day eventually if you wanted me to create an enhanced version. Don't worry I didn't take anything from there, you little greedy grubber. You did good today, plus look on the upside, by taking a beating everyday you'll naturally reinforce your body added in with this bath everyday your on the path of going beyond even me. Once you figure out how to infuse chakra I'll leave for the Land of Sea, so you'd better figure it out quickly if you want to save that Uzumaki girl. Though seriously I can't believe you're not even in the ninja academy yet. Your physique alone is nearing the limits of chunin, almost elite chunin level, same for your chakra, not to mention I've checked your chakra composition looks like your holding back on extraction, because you somehow have a greater quantity of yin chakra even though your a Senju. Which, by the way, is legitimately impressive considering your age. Kabuto gave me a breakdown of what jutsu you can use… looks like you're trying to be just like Second Grandpa."
Soutarou mumbled, "Well yeah, who wouldn't want to be like the man who made a million and two jutsu, styles, revolutionized the ninja world, is the real reason Konoha prospers the way it does, not to mention how damn badass he was."
Tsunade smiled and said, "Yeah he was pretty bad ass… as for all the jutsu he made… I think some of them would have been better off just staying in his head… but yeah he's probably one of the greatest geniuses to ever walk this planet."
Soutarou then realized something before saying, "Isn't it kind of weird you're in here when I'm taking a bath, you know naked?"
Tsunade grinned and said, "It's fine I'm a doctor kiddo."
Soutarou mumbled, "I would trust you… but your teammate's Orochimaru… and he's obsessed with kids."
Tsunade choked on air before coughing multiple times and saying, "That's just him ok?"
Soutarou grumbled, "The fruit doesn't fall from the tree…"
Tsunade gritted her teeth and the pair continued to bicker nonstop…
