Naruto: A Scientist's Way of World Domination!

[A/N: Sorry guys, I know I have been missing updates for like a month, I originally thought I should write after I explained some more stuff, but... I got stuck on explaining the time travel which happens in Boruto and then exams came up so... yeah. But, I've decided that I'll write a little bit each day instead of writing in big chunks when I'm free so hopefully I should be able to get out chapters faster.

Also... as this is the last chapter of the intro mini-arc, its a 'bit' longer than usual. You'll see the reason for the inverted commas soon.]

×××××××××××××××××××××

'.... There must be two ways of going about it. You could either manipulate the information going to the processor or... you could simply control the processor itself.

That is to say, you could manipulate the information input going to the brain to give it false information or, you could simply control how the brain processes it. In essence, it's like mind control but not exactly.

Hmm.... that opens up some new avenues... it implies that the normal genjutsu used by ninjas controls the input information by altering the signal midway through it's journey to the brain through the motor nerves. However, this makes it susceptible to detection.

However, if instead, you control the brain of a person directly, there's virtually no way to stop it. For example, the Kotomatsukami and Infinite Tsukiyomi. One alters how the brain behaves naturally while the other makes the brain believe that it's in a reality which doesn't even exist.

This world mostly goes on using instincts, they don't really look for much of a detailed explanation and I mean... why would they? They can spit freaking fireballs out of their mouths and run on water like Jesus.

This was the case in my original world too, people usually just don't care about the explanations as long as they can do something 'cool', they might as well be monkeys, only caring about big explosions.

Don't get me wrong, there's some joy in doing that too, but seriously, even those Naruto transmigration fanfic MCs who are essentially in the same situation as I am, don't care about using science to understand the world, they think it's useless.

I saw a pretty good response to this behaviour on the internet once, it was written by some random guy called 'Zeta_00', "Once you truly understand something, it's a trivial matter to manipulate it to your will."

Anyways, I trailed off there a bit. The point is, I only really need to understand the workings behind the world and different techniques. Plus I need to gather as much knowledge about the world as possible to know just how similar it is to the canon.

I'll of course need to train my body and instincts in that time as well. I have a lot to do... don't I? Speaking of time....'

Kagaku now looked over at the watch and saw that his self allotted downtime for thinking was already over and started to read the books he had been given before his theoretical lecture.

And like so, a few days passed in reading books, theoretical classes and rehabilitation.

~~A few days later~~

Kagaku had now recovered fully and was ready to be tortur... trained yes, trained.

In a few minutes, Axolotl would arrive to take him to train. Meanwhile, Kagaku could be seen sitting in a lotus position with a look of concentration on his chibi face.

He had decided to try out sensory ninjutsu and come up with a decent theory for the basics of chakra, chakra natures, chakra signatures, etc. While he didn't have much time to really prove his theories at the moment, as long as it works, there's no need for a decisive proof immediately.

He has just arrived into this unfamiliar world, and its all quite novel for him at the moment, he wanted to enjoy a little before going into the nitty-gritty stuff. Even someone as science oriented as Kagaku couldn't resist the allure of a fantasy world fully.

[A/N: I will post the said science focused chapters in a bit about this topic for now as its the basics. I'm thinking of naming it something like 'Kagaku's Journal' or something similar as a new volume. We'll see I suppose.]

Sensing had opened an entirely new world for Kagaku, it was like a '6th Sense' although some people consider the Sense of Heat and Sense of Gravity to be 'senses' so in a way its actually like a '8th Sense'.

Anyways, the best way to explain it would be an analogy. Imagine that you replaced your normal vision with thermal vision, or simpler, wore a thermal lens. Its like you see the world completely differently.

Nature chakra is in everything but, we don't sense it, why? Because its everywhere. And if its everywhere and in everything, for the purposes of 'seeing' it, it might as well be in nothing.

Its like .... a dull light blue version of the world with bright spots indicating higher chakra concentration. And pretty soon, Kagaku barely 'saw' a bright light in the form of a slightly contorted human being while leaving a trail of bright blue light in its wake rapidly approaching.

It was quite difficult to follow, the ridiculous speed wasn't something Kagaku was used to yet. He thought, 'So fast! Its entirely a different thing to know it and actually see it in action. If only I could see it a bit more clearly, I might be able to calculate the speed from the length contraction....

No, the change would be way too miniscule, any machine's error would probably be greater than then the Lorentz Factor anyway. There's no way a standard jutsu used by even some chunins could make one travel at relativistic speeds.

Oh, right! He's already here by now.' In fact, Kagaku's sensing range was abnormally high so, he could sense pretty far, it was tough to make an estimate however, he'll have to experiment to find out.

Pretty soon, Axolotl walked into the hospital room and while waving his hand said, "Yo! How you been kid? I confirmed from the medics, you're good to go now."

"Yeah, I was getting bored sitting in here all day too, are we going to the base now?" Kagaku asked in return.

"Yup, we're heading there right after..." Axolotl replied with a teasing and amused tone at the end.

"Don't tell me.... the mess right?" Kagaku said in an exasperated voice.

"Yup" Was all he got in return. He could almost smell the mirth in Axolotl's demeaner.

The mess was a source of embarrassment and annoyance for Kagaku, he would do everything in his power to not go there or not be noticed while there but, it never worked out in his favor. His future seniors just loved teasing their 'Kawai, Chibi Kohai' which just made him want to burry his head into sand like an ostrich.

~~A bout of daily embarrassment later~~

Kagaku and Axolotl could be seen walking out from the mess, the first ones too as Kagaku had insisted that instating him into his new home was very important and needed tending to as quick as possible when in reality, all the work was done by rookie anbu, this was their form of D - Rank missions.

Kagaku said with a hint of irritation in his stoic voice, "Can we go to the base already? My stuff should have already arrived there."

Axolotl sighed and said in a dejected voice, "Hah... you're no fun Kagaku. Fine, we can go to the stupid base." After saying this, he reached out his hand for Kagaku, by this point, Kagaku was pretty familiar with the shunshin and no longer got disorientated after experiencing it.

~At 'ANBU Headquarters'~

The 'headquarters' of the anbu was a surprisingly ordinary looking building complex... at least from the outside. At first, Kagaku was confused to see that they had arrived in front of just some random buildings although he figured that there was more to it than met the eye and he was right.

Axolotl took him to a random apartment and knocked while saying, "The Second Light and The Light in Darkness shall guide us in the future."

Kagaku thought, 'Well isn't that weird.... I mean what are they even talking about? The Light in Darkness? The Second Light? Guiding in the future? Is it just a wonky password or does it mean something? Oh well... I have a lot to do right now, I'll think about it later when I have more time.'

After a few seconds of delay, the room was opened but.... there was no one on the other side! Kagaku looked around in confusion to find out who had opened the door, only to find nothing.

Seeing Kagaku's confused state, Axolotl chuckled and said, "There's no one there Kagaku. Its voice activated seals."

Kagaku with a look of realization on his face, said, "Ah! I see. Seals are pretty useful huh?" while inwardly thinking, 'Ah... I see! Seals huh? Those are pretty versatile, I do need to run some experiments on how and why they work too...'

"Of course they are! Why do you think the Uzumaki are so feared by the entire world? Fuinjutsu is extremely powerful and extremely complicated, not just anyone can learn it. In fact, most ninjas who try it end up barely escaping unharmed after the seal they were working on exploded in their face. But, as dangerous and complicated they are, they're even more useful and valuable."

Axolotl paused and continued, "Anyways, you'll learn more about them if you have the aptitude for it. For now, we have to get to the base."

Kagaku just nodded his head and they went inside the room.

The room was a standard apartment with one bedroom and a small living room. The furniture was scarce and everything was quite dusty, as if no one had been in it for a long time. Axolotl just walked over to a flower pot and touched it. Kagaku could sense him putting chakra into the pot.

Suddenly, he could hear a faint rumbling noise and right before his shocked eyes, a rectangular section of the wall just disappeared into the ground! A somewhat narrow hallway was now visible. While a bit narrow, it was still enough to fit four people side by side comfortably.

Kagaku could see the smug, knowing grin on Axolotl's face seeing this, Kagaku quickly schooled his expression, 'No way I'm letting you have the satisfaction of seeing me shocked you budget salamander!' he thought.

Axolotl finally spoke up, "You ready to go kid?"

".....Yeah" but, as Kagaku got closer to Axolotl to allow him to shunshin them both to the base, Axolotl stopped him.

Seeing a confused Kagaku, Axolotl chuckled and said, "Your training starts now kid. We're gonna run to the base."

Kagaku's face paled as he said, "R-running?" He gulped and continued, "H-how far is the base?"

Seeing his trainee's expression, Axolotl laughed and said, "Well... I brought you to one of the furthest away entrance points which is still in the village and was closest to us, so we're about...." a sinister smile spread across his face as he said, "A hundred kilometers away."

Kagaku laughed awkwardly waiting for Axolotl to say that he was just joking but.... Axolotl didn't move a muscle and didn't show a hint of deceit in his voice. 'He... he can't be serious right? A hundred kilometers??? He's crazy! A 3 year old can't run that much!' 

Axolotl asked, "What are you doing just standing there? Come on, you got a lot of running to do!"

Kagaku cursed this crazy anbu he had gotten as a teacher. His days were not gonna go as smoothly as he had hoped. He even started questioning his past choices, 'Why!? Why the hell did I think it was a good idea to reveal myself to these sadistic bastards?!'

But, no matter how much Kagaku cursed Axolotl in his head, he still started running.

Just a few minutes later, Kagaku could be seen barely holding himself up, sweat covered his entire body, he was so... so tired and yet not once did he consider stopping. He wasn't even panting... to be clear, this absolutely wasn't because he was ok. It was because half his mind was focused on not doing so. He knew, panting would make it that much harder.

'God dammit! Why the hell did I agree to this?' 'Why am I still going?' 'This is enough, I've already done what I could.' 'I should stop' These were the things running through Kagaku's head and yet... he didn't stop. He didn't think about the monotonously spaced lights that kept going behind him.

It wasn't like the stories he had heard where the person didn't even once think about quitting. In fact, it was the exact opposite. All he could think about was stopping and yet.... he never stopped.

He wasn't quite sure himself why he didn't stop, it was all he wanted, all he could think about. But, his constant self loathing came to an abrupt halt as he realized that something had changed... he wasn't moving forward anymore... no, rather he seemed to be moving down as well.

He registered it too late, he was falling down. Truth be told, he was glad he fell, he would much rather fall down than keep going through that hell.

However, the expected impact never came and only then did Kagaku remember that there was another living being present. He... had been caught by Axolotl.

"Good. You performed better than expected... you even used chakra enhancement to keep on going. I wasn't aware that you were capable of doing that... although it seems you were doing it subconsciously."

'Ch-chakra enhancement? I seem to have learned it already huh? Althou-' No matter how much of a genius Kagaku was, he still had a body of a somewhat normal human. Willpower and chakra reinforcement could only make up for so much. Hence, thinking this, he blacked out.

Axolotl didn't seem to worried, as if he knew it was what was gonna happen or rather... it was what he was hoping would happen.

He didn't bother saying his thoughts out loud and just started using medical ninjutsu on Kagaku.

Unfortunately for Kagaku, the only thing he heard when he woke up was, "Oh? You're awake now. Good, now get to it, we don't have all day. I want 10000 pushups. Now."

Kagaku tried to protest as soon as he registered Axolotl's words and said, "But I-"

 "And just for your information, we're already inside the training ground of the base. You collapsed in the middle of the base." Axolotl cut Kagaku off. 

He continued, "Anyways, start now or it will take even longer to finish."

By this point, Kagaku had realized that arguing was useless and simply started with the push ups. His body wasn't quite in top shape but he felt much better and could be considered about 80% recovered already.

This happened a few more times. Each time Kagaku was fooled into doing even more than he was asked to do at the beginning in his confused and exhausted state. Each time his chakra control and enhancement technique improved, each time he fainted and Axolotl healed him, each time he was given a new exercise which targeted a new group of muscles.

At the end, when Axolotl finally said that they were done, Kagaku collapsed onto the ground and this time, not even medical jutsus would wake him up anytime soon.

Even after he woke up a couple hours later, he wouldn't catch a break as he had to go through a theory lecture almost immediately after he thought that the hell was finally over.

Only then did he get a 30 min break... or so he thought because that's when he was asked to perform chakra control exercises for 2 more hours.

At the end, he was utterly exhausted and this time when he fainted, he didn't wake up for several hours.

When he finally woke up, he was in the grassy fields of the training ground but now, there was a table full of various weapons like kunai, shuriken, tanto, katana, etc. There were also a couple of human shaped targets at various distances from the table.

A few sturdy looking targets could also be seen to the side, likely for close range practice.

As he took this sight in, Kagaku realized that his tortu-training... wasn't over yet.

"Well well, so the sleeping beauty is finally awake huh? You sure slept like a baby." Axolotl's amused voice rang out.

Kagaku shouted in response, "That's because I am one you psychotic nut job!"

He now had dark lines over his head and said in 'sad' tone, "Aww... sensei's hurt his student doesn't like him anymore...."

"Quit your overacting and tell me what I have to do."

Axolotl seemed to brighten up at that. He said in a jovial voice, "Well, now its time for weapon training! Exciting right? We'll start with the shurikenjutsu first and then move onto kenjutsu.

Of course, that's just the general category and we'll try out a bunch of different weapons to see which one suits you the best. Although, regardless, you would be advised to learn the tanto/ katana and kunai/ shuriken combat."

"I see. Do we use chakra or not?"

"Nope! You should get used to throwing it without chakra as most of the time they're used to conserve chakra. Anyways, enough chit chat, lets get to it!"

And from then on, until nightfall, Kagaku trained in various weapon techniques.

In fact, there wasn't much to it. Any time Kagaku started to get even slightly used to the training regiment, the difficulty was increased exponentially.

Amidst the grueling agony that was training, he continued without stop, he kept developing his unique genjutsu and before he realized it.... a lot of time had past.

~~10 months later~~ Konoha Year 52, Kagaku Age: 3 Years and 4 months

He had barely managed to develop his genjutsu in 10 months time. He had now become much taller than an average 3 year old would be, he was about the height of a 5 year old. That wasn't all, his body had lost most of its baby fat at this point and condensed muscles could be seen on him.

He had started to get used to the constant torture at this point, not to any specific difficulty, but to getting exhausted itself. He could now think clearly even when his body didn't respond to his will.

The completion of the long awaited genjutsu meant that now, he could finally get to performing his experiments to confirm the laws of physics he knew still applied in this world or not.

This was, the most important step. After all, if you understood something, its trivial to manipulate it to your will. It was why he pushed so hard to get to this point, not only did he need to do this, he also enjoyed doing so.

He of course, tested it on animals first and gradually worked himself up to a civilian toddler to a grown adult to a genin and eventually.... he managed to ensnare Axolotl as well. Naturally, he paid Axolotl back for all the torture the bastard had put him through and went on his way.

He decided that the Forest of Death would be the best place to build his base. After all, the absurd amount of chakra and chakra enhanced beings would cover up his own chakra especially since he built the base underground.

There wouldn't be much surveillance either so it was basically the perfect spot as long as he himself stayed safe from the ecosystem of the forest which wasn't much of a problem either thanks to the 10 months of hell he had went through.

And so, Kagaku kept sneaking away from training by substituting with a shadow clone as soon as physical training ended as everything after, the clone could just return the benefits back to him.

[A/N: Apparently a common myth, but, 'muscle' memory isn't actually stored in the muscles, its stored in the brain like every other memory. So the SC(Shadow clone) would would give him those back as well.]

After a few weeks, Kagaku had built his underground base with all the equipment he needed which he 'borrowed' from a few extremely kind individuals who donated to his cause.

And thus, Kagaku began his journey to bring science to this world for real. These poor souls were unaware of the magnificence that is science.

By this point in time, seeing the approaching war and Kagaku's performance, Axolotl had already started teaching him jutsus a few months ago. The earth release definitely came in handy for making the base.

And so... Kagaku immersed himself in his training and experiments. He had already planned out his course of action for the future, he just needed to act on it now.

After all, the Second Shinobi 'World' War was right around the corner.

~~8 months later~~ Konoha Year 52, Kagaku Age: 4 years. 9 December 52

[A/N: That's right, back to back.]

Kagaku could be seen thinking in his room in the anbu headquarters

'Its my birthday today, interestingly enough, they follow the christian calendar too, its just that instead of BC and AD they follow CWE (Clan Warring Era) and MVE (Modern Village Era) which began with and is thus synonymous with KY (Konoha Year) but the other villages like to disregard Konoha's contribution to it much like some atheists tried to disregard the christian calendar's religious origins in my previous world.

Anyways, as usual, all my anbu senpais came together and threw me a party despite my protests. Last year, people had done the same but in the gifts, they mostly gave books or scrolls for various techniques but this time.....

He had received a bunch of weapons. Rabbit, the annoying one had given him a chakra conducting katana while Eagle, the anbu captain had given him a (CC) chakra conducting chokuto. His sensei, Axolotl had given him a set of CC kunai and shuriken. While the others gave him some normal ninja equipment like smoke bombs, senbons, explosive tags, etc.

At first glance, one might think that they were simply giving ninja equipment to him to allow him to practice better but Kagaku knew what it really meant.

When Kagaku saw the gifts he froze for a moment. Being experienced ninjas, everyone immediately noticed it and Axolotl asked, "What happened Kagaku? Do you not like the gifts?"

Kagaku's happy expression disappeared and he replied in a neutral voice, "You don't have to play dumb, sensei. I can see that... its finally time."

Rabbit put an arm around Kagaku's shoulder and said, "Oh come on kid, you were pretty excited to become an official anbu member weren't you? Cheer up! This is the gift we all prepared for you!"

Kagaku looked at her and said in a cold voice, "Don't pretend like you don't know the real reason for my selection. No matter how much of a genius the village may think me to be, there's no way they would deploy a 4 year old to the battlefield. The war's finally here huh?"

The cheerful atmosphere of the room disappeared as every single person looked at Kagaku with a sorry expression and nodded their heads.

Kagaku looked over to Eagle and said, "I understand that the situation is much worse than what was conveyed to me, captain."

Eagle just looked down with gritted teeth and clenched fists and replied, "..... Yes..... I'm sorry but we can't keep an asset like you away from the war any longer."

After an uncomfortable silence, Kagaku spoke up, "I see. While I don't particularly mind, I would like to know the whole scope of the situation."

From the side, Axolotl said, "No... its your birthday today. You should enjoy it as much as you can... like a normal kid your age."

Kagaku smiled self deprecatingly and said, "Since when have I been a normal kid? .... But you're right. I should enjoy these moments which may never come again."

Sometimes, the Kagaku's maturity saddens the adults. 'A kid shouldn't be thinking like that.' is all they could think hearing Kagaku's words.

Rabbit was the first to snap out of it and said in jovial voice, "Anyways, lets get this party going!"

Everybody knew it was just temporary distraction, they knew that from that day onwards, something that went against the entire principle of Konoha's founding would begin... a 4 year old would be sent out on the battlefield of war.

But... they didn't quite care anymore. As Kagaku said, these moments may never come again. A ninja's profession was death. No one could be certain what happened next, which mission they could end up dying on. So, it was best to distract yourself while you could.

And so... Kagaku and his anbu companions enjoyed the rest of the day as much as they could and before they knew it, it was time to wrap things up.

While they were putting everything away, Kagaku spoke up, "So... when am I supposed to join?"

"..... tomorrow." was all he got in return.

Kagaku responded in an aloof tone, "I see.... I'm assuming I'll be in the logistics department at the start correct?"

".....no."

Kagaku was taken aback, "Not logistics? Then what?"

Eagle replied, "You're in the Hogo squad."

"Hogo? You mean... the protection squad?"

"Correct."

"Who am I supposed to be protecting?"

"..... that.... I can't disclose to you right now. You will be informed when your graduation ceremony takes place tomorrow."

"I see."

After this short conversation and a few goodbyes, everyone was off on their way. They had to get some good rest today. After all, tomorrow was a big day.

×××××××××××××××××××××

[A/N: Phew.... 4.4k words, longest chapter to date! That's like 3 and a half times the first chapter. You should be expecting another chapter soon too, Winter holidays are coming up. Although... exam season is too so I guess we'll see.

Anyways, be honest, those back to back time skips caught you off guard didn't they?]
