Rimuru pov
"Aghh where am I it's all dark"
[Master your awake]
"Ciel? What happened I was about to fight yuuki wasn't I?"
[Yes master we were about to fight yuuki when he activated a magic circle which sent us to the end of time/space]
"Wait then let's hurry back quickly let's go, what are we waiting for!"
[That was more then infinite amount of years ago master]
"Huh?"
[That was mor-
"I heard that ciel, that mean we lost right?"
"Everyone's dead right?"
"Yuuki won the war"
[You could recreate the world and all there memories]
"NO THATS NOT THEM THATS JUST A FAKE"
[then how about master goes back in time?]
"Wait I can do that?"
[Yes since master has been here so long you have managed to surpass veldanava during his prime state by anuncountable number as such you can even create infinite number of hyperverses with no powerloss]
"Huh Wait what!?"
[You have transcend reality and could destroy time, space and reality everything and the things that exist outside of everything with just a thought]
(A/N: this is not cannon just my fanfic, because I can I made him way too op and on par with cosmic Rimuru, twas necessary to make future events work)
"You knew I was going to pick this way didn't you?"
[My my I have no idea what you mean master]
"Khahaha"
[Well then let's go back in time shall we?]
"Yes but do you know how to use this power?"
[I have not yet used the power of time travel so there is a 70% chance of going further back then you wish]
"Well then let's just try and hope for the best, since from what you said I can defeat anyone"
[Yes I have tested your power of destruction and creation and nearly destroyed time itself so no need to worry about anyone harming master]
"As expected of my partner, well then let's try go to the point of right after yuuki sent me to the end of time/space"
[Right!]
As soon as ciel activates the time travel Rimuru suddenly hears a voice
"Hello young one"
"H-hello?"
[Master it seems it failed I have managed to analyse what went wrong but I think this will be fun]
《Why what happened?》
[Unexpectedly through your soul corridor with velzard you have been sent back in time and I'd now baby velzard you are currently being named by veldanava]
《Huh what so now I'm velzard?"
[Indeed]
《Hmm well it might be fun to start off as a true dragon and get to meet veldanava or I guess brother now》
"Hmm yes your name shall now be velzard the white ice dragon I will also give you knowledge of the truedragon race"
"Brother?"
"Awwww your too cute!"
"Cute?"
《Wait ciel I'm velzard now right?》
[Yes master]
《So I'm a girl now right?》
[Yes master]
《Well crap I'm a girl now》
[Muhahahhaha]
《Nooooooooooo ciel!!》
"Velzard you okay?"
"Y-yeah I just got a bunch of information I was trying to understand it"
"Oh I guess it would be weired suddenly getting a bunch of information"
"Mm we're am I?"
"Oh right(chuckle) this is my greatest creation the Cardinal world this is where you shall live for now but if you get strong enough you might be able to leave this world"
"Wow big brother created all this!"
"Mhmm I know right so amazing praise me more"
"Brother the best!"
"Ahh feels so nice to be praised by a cute child!"
"Hehe"
《Ciel help me I didn't realise veldnava was veldora 2.0!》
[Actualy veldora is veldnava 2.0]
《Oh true.. but still this will be a pain》
[You can always punish him when your older since it would be a bad idea to show your full strength right now]
《Oh yeah can you limit my power and slowly give me power to match velzard but give one of the strongest barrier that veldnava can't detect up incase any sneak attack》
[As you wish but no one can sneak up on master with me around!]
"You've spaced out again"
"Oh sorry brother I was just wondering how much power I have"
"Hmm try hit this"
A big wooden dragon appears in front of velzard and then he/she hits it with all there might magic attacks which blows up a 1 mile range
"Wow to be able to do that at such a young age your very strong"
"Hehe, I'm very tired now though"
"Yeah I guess you would be quite tired wouldn't you, you just hit it with everything you had and I'm very surprised with you control over magicules even I had to spent a week practicing it and I was the one that made it"
"I very strong?"
"Indeed you could rival even the 7 primal angles and demons"
"Are they strong?"
"Yes the angles keep the heavens protected and the demons keep the underworld protected there is a realm underneath the underworld but that's for anything that is too strong for even me too handle and I can seal it there but so far nothing has managed to reach my level"
"Ooo so I'm very strong and you very strong"
"Haha I guess we are quite strong aren't we"
"Can I meet the 7 primal angles and demons soon?"
"You will probably meet them on your own"
"Hehe I hope so"
"So you want to explore this world? There is much to do here like Learn magic you might even be able to turn into a human form like I am one day"
"Ooo how do you turn to human"
"Well you have to try feel the dragons core within you and shape It into a human and your body will change with it"
《Ciel》
[On it]
"Wow your amazing and your quite beautiful with that snow white hair but first you should put some clothes on"
"Oh I have no clothes"
"Yes I can see that"
...
《Ciel what the hell!!》
[Sorry master, all the clothes within the (stomach) were disintegrated as they were all old and we don't want veldnava to get suspicious and create clothes, so ask him if he has any clothes on him]
《Oh okay that's fine then》
"Does brother have any clothes I can borrow?"
"Oh right you don't have any clothes you were just born"
"Mmm"
"One second let me just
[creation lord ahura mazda]
Here you go sorry about that"
Velzard puts on the clothes
A/N I'm going to be calling Rimuru velzard from now on since veldanava technically renamed her so yeah Rimuru is now velzard
"Much better now you have clothes and aren't naked for the world to see"
"Mhm thank you brother(smile)"
"Huaaaa too cute"
"I want to explore the world I haven't seen any more than this wide field"
"Oh right yes let's do that then, so far there is only small human civilizations such as villages and small towns to avoid the mindless monsters but the ones who have a mind also built some villages such as orcs lizardmen goblins and ogres"
"What are humans and monsters?"
"Right humans are a a species that looks like the form we have right now they have a small amount of magicules in the soul to keep the body working and monsters are made out of magicules still have souls but they can put magicules inside of there body to use later but they have a limit or there body will explode"
"Oh so monsters stronger?"
"Yes monsters are stronger but humans are smarter which is why in 5.000yrs I've told the angles to do an attack every 500yrs to keep the humans from getting too advanced and destroying the world but that's only for this world the other worlds don't have angles or demons so humans will most likely destroy all of those worlds and this will be the longest lasting"
"Brother know so much"
"Hmph I am the smartest of them all no one knows more then me!"
"Hehe"
《Is this guy serious》
[No I am the second smartest since master went beyond omni status I took on the omni status meaning master is the smartest if he puts his mind too it however I managed to turn of your all knowing as I found it only hurts the user]
《As expected of my partner》
"Anyway back to the explanation, the humans will come together and form even bigger civilizations and maybe even have millions in a single "empire" as I named it"
"Ooh an empire have millions of humans, why not monsters though?"
"As I said humans are intelligent so they will likely push back any monsters and stop any town while it's still small"
"Oh that's sad so humans are intelligent but don't like things that aren't them?"
"Indeed you catch on quick"
"Hehe(smile)"
"Ahh I could die now and be happy"
"Nooo don't die I don't want brother to die!"
"(Smile) I won't die, wanna know something cool?"
"Yeah!"
"If either you or me dies we will be reborn and come back"
"So cool!"
"Mhm I know right I made it so you and me are the strongest no one can ever kill us!"
"Hehe"
