You could see Madara walking in a forest, looking for a bandit. He had been teleported into an orphanage, in the bag that Matsuo had given him was a few books and a note saying that he bribed the owner of that orphanage to write Madara down as a long-time inhabitant.
The books were all temperarily closed and only useable when he became a chunin, so Madara showed some talent and joined the ninja academy and skipped a year and learned the three basic jutsus after. They were too bad to learn when he was still alive before, and he sadly couldn't use his old sharingan to learn it instantly.
He looked behind a tree where he heard rough breathing originating from, a wild bandit appeared! Dying though a kunai in the skull, a sad way to die.
He took out a book and opened it, he was slightly happy that the book had opened. He wanted to see what that mysterious personage had put onto his platter, what was written was in kanji, or words of power.
I glowed and showed him, Madara, in a white plane. He was in a relaxed position, when the words 'Fire style; flame burst. Create a ball of fire out of your fists.'
Another line of words appeared beneath it 'Basic mastery;' The two liness then shrunk and hid in the corner of the image. The Teacher Madara, now T. M., got into a stance.
T. M. slowly drew back one of the two fists that were in position, and slowly made his body make way for the fist. When the fist was at his side, his side shifted around 30 degees along with the fist until both stopped.
Then the fist rushed forwards with the twist of T. M.'s chest, when it stopped a burst of flames exploded into a cone from that fist.
This then repeated with the chakra and chakra pathways visible, at the fist there was a square plane that chakra used for nature transformation. The swirling chakra rubbed against the plane, creating a volitile vortex ready to explode the moment it is no longer supressed.
It was then exploded forcefully into a cilinderical form, forcing the energy to push out into that cilindrical form and could no longer change. There were a few deminstrations of this with different explosion shapes, T. M. dabbed twice and said "Good luck me, I'm sure you'll do it! Think of beating up Harashima with this! new recordings will be unlocked when you master what has been shown. You can open this page again to see simulations of people battling with this level of the technique."
The projection turned white for but a moment then closer into nothingness, and the book closed once more. On it was a piece of paper saying 'I can update this book whenever I feel like it, so a piece of paper like this will appear when that happens... If I feel like it. The brown book is for jutsus, genjutsus and taijutsus and similar stuff, the red is for progression of a path and fundementals in a bunch of stuff, the blue is a collection of stories for your entertainment, the blue one does have different view points and experiences with different paths and skills though.' The paper dissapated into a silver for and slowly faded.
Madara found the new jutsu amazing, exploding fire attribute chakra to not have to do anything yourself except making the chakra! This was all without any need for a hand seal either, this could be used at higher levels for a suprise attack!
Madara quickly opened the to book to the only open page, he noticed this time that even after flipping out that page, it was as if it was replaced. This time when the projection opened it asked 'demonstration or simulation?' As if sensing Madara's sub-concious, the word 'demonstration' dissapeared and the word 'simulation' enlarged then faded too.
It was replaced with two people, one with rough armor riddeled with wear and tear and a grizzly appearance with the word 'Untalented experienced veteran martial initiate', and another in new white and golden armor with a valiant and innocent appearance with the words 'Talented newbie naive martial initiate'. At the top there were the words 'Chose', in the corner it said '*simulator in progress, new options and a character creator may be involved in future updates'
Madara found the veteran more favorable, and so the same thing happened before the young man dissapeared, the old veteran took the stage.
Two 2d bubbles sat at both sides of him saying 'Time loop battlefield' and 'Martial journey', Madara was leaning to battlefield and he didn't understand what 'Martial journey' meant. And as such Martial journey dissapeared and Time loop battlefield glided beneath the veteran.
Another question was asked 'Choose difficulty; 1 to 10', Madara was leaning to 10, so that was his choice.
The projection turned black with a timer '2:23:59:59' with the words 'Come back in three days for nature energy to be harvested or channel chakra into the book to decrease the waiting time.'
Madara closed the book calmly and put it back into the bag, the blue book seemed like the old book Matsuo made a long time ago, the one with magic circles and stuff about Madara being the protagonist's likeness donator.
Madara showed no interest in the other books and started to look for a place to stay for the next few days, he had finished this mission too fast. He had only shown good talent, not monsterous talent.
Back in a cave Matsuo was relaxing nicely, in the next room there were thousands of shadow clones constantly writing down kanji. It was like a sweatshop but space were actually a thing, and they making anything they could think of.
This sweatshop was the beginning of the simulator, first, a clone group that felt that making calculations all the time for making a good fuinjutsu was too troublesome, so they made a basic acubas like fuinjutsu to not have to do commoner things like 'add' and 'subtract'.
Then they upgraded it by just having to put in the numbers in kanji then made it so that it was reuseable, then they added in multiplication. Then they expanded it until it became a modern calculator, in the end they got a calculator up and running.
This whole process took about 3 months of constant work, when the original Matsuo looked through his memories because he was bored he saw the calculator and was amazed, the fact that a computer could be made with fuinjutsu was just amazing. A calculator is a computer by the way, although it isn't one of those epic gaming pcs doesn't mean it isn't a computer!
Matsuo did in fact get excited with the idea of gamer laptop paper, with his immense amount of chakra regeneration he had made a ninjutsu, genjutsu, taijutsu and fuinjutsu sweatshops. Along with the perma clones with really high chakra regen who also make more clones. There was also a chakra economics sweatshop about getting more chakra regen and all that.
He had long since retired his position as Final Line and had given it to that old man now young man, the entire reason he even did that was to get experience in acting cool and fighting.
He had the updating from a distance down a few years back, it just costed way to much time to make and too much chakra too power. Now that Matsuo had a void source rank 5 close to rank 6 that all wasn't a problem, he had just replaced those three books with the updating ones.
Every single breakthrough of every single one of those sweat shops was recorded in those books except fuinjutsu, it was too OP for him not to create a monopoly.
Fire blast was one of his earliest works, then refined by 120 clones to an unbeliveable degree, they took a few weeks to get rid of the pre-use hand seal needed to, well, prepare for using the jutsu.
This is the perk of having shadow clones learn for you, actually, high shadow clone jutsu, it was called high because of all the improvements Matsuo's and his thousand jutsu shadow clones have made, was already lvl 63. Which is impressive too say the least, I haven't actually seen shadow clone jutsu as that level yet. Since normally you can't use shadow clones to train shadow clone jutsu, and it takes a while for your chakra to regen.
Matsuo was counting his money through a shadow clone while also having his bones broken and healed every few seconds, pills made from the 'survivability and regeneration of the body' and 'martial arts' wings had worked together to make a pill that sped up the nourishing and healing ability of internal energy by a few dozen times, it was expensive though.
But for the great billionare capitalist Matsuo this was of no problem, he was happy and satisfied. Although the main mission and side-missions weren't possible right now.
[Mission; cause great chaos throughout a region, or turn it into a wasteland]
Not going to happen, not now at least.
Matsuo was content in life, he was one of the richest people in the world, and was pretty much unbeatable against anyone except the kages or the otsutsuki bloodline and its derivatives's leaders. 'Just stick my clones on their ass!' That's what Matsuo said he'd do if he had to fight with anyone.
But then a certain clone chain finally ended, Naruto was finally done with his teachings and was in his battle with Zabuza. Matsuo felt weird, how did this talentless hack Naruto skip a year or two? He even knew rasengan! That other guy was helping him, not that I really mind. As long as his arc goes well and he can personally watch the world tree become one with Madara, giving birth to tree hugger Madara. He'll be satisfied if he just doesn't die to Kaguya while he could do the previous two things.
Matsuo did feel bad Zuzuki, he didn't even have a single perma clone! He was still a chunin! Although he seemed to have the strength of a jonin, he's still a weakling.
Matsuo stood up, ending his eternal torture, and undoing all the torture clones. He took out his greatest creation (Stolen from the system). The starlight leap ticket, it takes 500 clones two weeks to make one of these! He has a few thousand make them and has a large stock pile, escape whenever! Matsuo inc!
He turned into silver light and appeared above the bridge, Matsuo took out a book called 'The akashic record'. He named it like that since it was his remote updater and multi-tool for everything, from storage to recording, a lot it possible with it, and if Matsuo finds something it can't do. Well... The slav- clones are going to need to burn the candle at both ends.
One of its myriad abilities, is not flying, but the sweatshop is working on it. It also has the simulator, every story ever written by the sweatshop workers in their boredom, a few pages with sealing fuinjustu on them that Matsuo could use by ripping them out.
Right now the story was at the 'Gato betrayed Zabuza!' stage, just right for Matsuo.
He closed the book with a hard clap, while he was falling down. If you're worried about breaking the bridge don't be, Matsuo had a litteral sweatshop making new ninjutsu every day, having one that slowed your falling was pretty simple.
He gently touched the ground, and clapped "Wow! What a twist!" He said in fake amazement "But those who will die will still die no matter what I try, so I'll be skipping this part."
He used wind transformation to quickly kill them all, by decapitating them. with "Wind style; mass decapitation!" A cheap and reliable way to slaughter mortals! Created by 14 clones over a year! Made recently, so it isn't that strong though.
A long, silent, akward pause came to being. Matsuo was the one who broke it "Uhhh, what should I say now? I really should've thought it out more." He murmered it to himself, he snapped his fingers in his ingenious genius.
Matsuo pointed at Kakashi, and used chakra to speed himself up, and jabbed out his sharingan. Matsuo opened the akashic record and put the eye in, Matsuo looked at Kakashi who was currently in serious pain, and said "Stop over reacting! It's not like it's the first time I took it out."
Matsuo laughing at the suffering Kakashi made Kakashi pause "What? This isn't the first time?.. Wait... Final Line!" His one eye constricted in shock.
Matsuo said playfully "Finally remembered me, and call me Matsuo Uchiha, okay? I'm retired now~" Matsuo walked forwards and petted Kakashi, when he fought against it. Matsuo broke both his legs with his foot, he said with disdain "Weakling, trying to ruin a good seedling with your mediocere strength, lording over him about how 'team work means everything'. I hate people like you, trying to force your ideology on others while not having the results that prove it."
Matsuo looked around "What was I doing again?" After thinking about it he said "Ah, right. I heard fighting and it got boring after a while so I interfered! Let's make the best of the situation!" He casted a few shadow clones, he also threw a kunai at the two other mercenaries Zabuza and Haku, they both blocked and Matsuo activated his sharingan. Showing 2 tamoe.
Here's where the culmination of a few clones over 2 years is now shown, ten kunai thrown bouncing off of them selves and the surroundings, attacking all at once after 2 seconds. quickly killing both of them, well... Haku was barely alive but unconcious after a clone punched her at the back of the head.
The kekkai genkai was good, though there was a bloodline limit like with the Uchiha bloodline, he used a few billion a year-and-a-half back to break it though. And all he wanted to do was copy what the bloodline did, so no billion ryo wasted.
Matsuo started to think, while his clones were harvesting roots and had infused them into his source. after ten seconds this was done.
Matsuo was again lost, he remembered that Sasuke should have the potential to become cool like Madara... So... "Yello hair, idiot with undeserved blessings. Pink hair, useless trash fangirl that gets in the way. Black hair, edge lord with potential for great things without a fucking tailed beast giving you all the chakra you'd ever need, a good seedling, 'seedling' is emphisized."
"Now, what should I do?" Matsuo said to himself "He's a seedling so I should give him something good like the previous seedling Madara..." Matsuo opened the akashic record, it started flipping quickly. It stopped on a page, A book appeared in his hand, he threw it at Sasuke and said "You should be able to use nature transformation to make fire attribute chakra, so in that book is how to make lightning attribute chakra and a practical support and attack jutsu of that attribute."
Matsuo signaled for him to open it, after he hesitated a bit he opened it. It just said 'Error; 001', he looked at it, then at Matsuo, he seemed angry. Matsuo was suprised "I thought I had already done that... Eh, who cares."
His book again started to flip through the pages, and this time started to glow. The book given to Sasuke also started to glow, Matsuo put of few chakra strings on it from a distance and pulled it back. On it, it said 'Updating... Put in chakra to decrease waiting time.'
Matsuo put in chakra equal to his regeneration, the past words were subsituted with 'Done.', and it clapped shut "Done." Matsuo said, he then threw it back. He also added on some spy ware and a way for him to gift the seedling some things, be it good or bad.
Matsuo again looked lost, he had an idea "What ever happened to that island Aether went to? Actually, what happened to Aether and Abyss? I remembered they were in a standstill, shouldn't it be in a few months when the horde comes out? I guess that'll be entertaining..."
Matsuo took out a ticket and ripped it, turning into a flash of silver light. And appeared back in his seat, he sighed. Matsuo has been having problems remembering long-term memories, but he didn't think much of it.
He's also been tired recently 'eh... who cares. It must be me using chakra too much, all those shadow clone usages are catching up and the strain has caught up. Using too much chakra should just put a burden on your soul...' He canceled all the non-perma-clones and told all the perma-clones to cause a great disaster in a few months as Abyss with Xenomorphs, with one being Aether looking from a far. If the disaster isn't stopped after a while they should have a bunch of perma-clones work together as castaway space travelers with a truce that has expired.
When he undid all the sweatshop workers and the unnecessary clones he made for fun, he felt even more exhausted 'Lets... Make some clones to take care of me while I... What was I thinking about, ah yes, the clone.'
He quickly made 3 hand seals tiger-serpent-dog, there appeared a clone, out of the real Matsuo came a crystaline rank 3 crimson source. Matsuo's control was lost and the source fell, just when it was about to fall the clone picked it up, with a painfull expression. The clone was entirely lucid, and his real self being unable to do something it had, through shadow clones, done more than ten million times.
'What... Now...?' Out of habit the tired Matsuo opened the akashic record 'Ah yes! the two indara incarnations!... Lets let two books update to update the two of their's books...' Matsuo's eyes closed, after a few seconds it snapped back open.
Matsuo looked at the clone, sweat started to drop from his chin, far to quickly for a human. His look told a few words, just five 'You know what to do' and went limp.
The clone walked infront of the original Matsuo, and took the akashic record. He used a ticket and teleported to an extremely hot place, it was a box of tungsten. There was a copy of a marble pedistal, but made of tungsten. It had a bunch of words of power on it, creating a force that was letting the fake akashic record float above the pedistal with golden light.
Though all those big words of power hid the storage function in the hollow tungsten pedistal, the fake one has some of the smaller secrets that you could deduce with some talent including two forbidden techniques called 'Fire style; hell fire' A wannabe blaze style flame that doesn't really go out due to the life force, or yang energy it uses to actually burn. It does reduce your lifespan, but that's a secret, that's why its 'fire style' and not 'forbidden art', and that only results in loss of life span if used too much.
The other is; 'forbidden art; great glacier' This one kills the user to create a great glacier with a size of at least 10 km across, since its only able to used by a kage or higher and you need a high control over nature transformation of both water and wind. The average person that can use this has a around 50km~ across, so most people will believe it as a great jutsu, but it's cost is your soul too. So no pure land for you~, this is explained in Madara's book though.
This box was under this world's crust, this entire box had more than a hundred layers having the highest level of fuinjutsu the sweatshop made, giving heat resistance and cooling effects, including the increased melting point fuinjutsu and it naturally high melting point combined it can not melt in the magma. The real Matsuo and his clones don't even know where it is in reality, there's just 22 space anchors that let him teleport in there per square meter on every layer.
The shadow clone ripped another ticket and appeared on the ground of a island, it seemed like even the ocean around it was filled with Xenomorphs. The shadow clone did as if it was cracking its neck and said "This is going to be a pain, at least I can accept rewards for the real me."
