Reborn in Mushoku Tensei with Unique Skill Great Sage

...

Arthur's Pov

I returned victorious from the recent events, having earn more than what I had anticipated and I started training my wives with more effort, honing their abilities and their method to use their skills. They have got quite the results from the evolution, especially Maria who once was but a mere beastwoman.

Maria had got three Unique Skills, First One was Sound Manipulation, Second one was the Voice of the Mermaid and third one was Cook, yes she gained a skill that was only supposed to be acquired by Shion and it was exactly same again suggesting that Tensura's main timeline was before Rimuru reincarnated. She is almost at Peak Universe level just a bit short of becoming a Multiversal being.

Anyway after her, Ghislaine evolved to a Soul Beastwoman, just a level lower than the current Maria who is a Divine Beastwoman, Ghislaine gained two Unique Skills, one was Sword Flow, and other was Divine Body. She is quite strong as well, her physical strength is off the charts and she is capable of blowing stars with simple swings of her swords as of now, and by stars I mean stars bigger than sun by a million times at least.

Both of them acquired a ton of powerful Intrinsic Skills as wells making them quite versatile. Then comes my other wives all of who have gained a ton of Extra Skills and Intrinsic Skills, Zenith evolved into Dragon Saint, a Unique Race that held the advantages of a human saint of being a Spiritual lifeform and basically immortal and granting her intrinsic skills of Dragons and her Unique Skill Dragoness Lord was a cherry in the top.

Hilda was Saint Fire Spirit, her prowess rivaling to the lower spectrum of Tensura Demon Lord and she had gained the ability to manipulate the concept of heat, kinetic energy, etc. as her intrinsic abilities, and her Unique Skill Warper was somewhat interesting and powerful. Her skill helped her to wrap over the concept of space, time, and reality partially, and she wasn't the strongest among my wives despite such an ability because of the limitations of her Unique Skill and her pitiful mastery over it.

Lilia, became a Marquiss Demon Saint, another Unique race, it grants her the immortality of both a Demon and Saint, making her immortality stronger than even Maria's, she also had the Intrinsic Skills of a high-level Demon, and the only reason she couldn't evolve into a Demon Duchess was because of her lack of experience and her age. She also got a Unique Skill, and surprisingly it was Reflector.

Norn and Aisha had got the same racial evolution result as their mothers, with same intrinsic skills, they only lacked a Unique Skill, though they had the potential to awaken them. It didn't matters to me much as all my subordinates' Unique Skills could be accessed by me, and I could bestow a copy of any suitable Unique Skill to them.

Now Eris got the most interesting race, it is named as Demonic Spirit Saint, yes it's name is somewhat silly, but she had gotten the most Intrinsic skills out of any of my wives, her immortality was nothing to scoff off either, she had the immortality of three immortal species overlapped, though due to her Demon and Spirit Side occupying only 50% of her race, her immortality was only almost the same level as Maria's.

She had the Unique Skill Divine Enigma, whose capabilities were somewhat baffling and Unique, under right circumstances she could beat opponents stronger than her. Finally comes to Nina and Isolte who gained the races of Water Spirit Lord Saint and Thunder Spirit Lord Saint, they had gotten quite the prowess boost as well.

They respectively held the Unique Skills Severance and Patience, each being a powerful on their own right. Now, due to my Ultimate Skill Domination King Abhoth, I could use their Unique Skills, not that I needed, considering a single Ultimate Skill was enough to go against all of the Unique Skills they possessed, but their Unique Skills were capable of evolving into an Ultimate Skill, then it will be the part of my Skill will come place.

Though my plans remained to distribute any Extra Skills that they were suitable with to them once they got the hold of their current abilities using my Ultimate Skill. Finally, I finished with my deep thoughts I yawned, anyway it was time for the breakfast, as always I got on the dining table, my wives came one after another giving me kisses, and hugs.

Minerva sat beside me,' Dear, do you have plans to expand this world? Or make it stronger? ', she asked me, and I became a bit silent, pondering over it for a second," Teach!", I sighed and looked at Eris who had a pout on her face," When will you make me your woman?! When you returned you spent the night with all of your wives throwing us three and your daughters out!", she said with envy.

" When you will grow up", my answer being blunt as she gritted her teeth, "~Eris~", Hilda suddenly called her name in a sweet tone causing Eris to trembled, her mother had quite an neutral look, in the end she looked at me for help, but I ignored it," Leave it Hilda, my son had just returned! Spare him of this drama!", said Zenith as she snorted.

Hilda sighed and nodded, making Eris feel relieved who quickly sat on her chair grumbling. Nina and Isolte were dissatisfied as well but they didn't lash out like her. The food appeared in front of everyone," It would seem my job as a cook is finished", Maria said with a sad sigh. I chuckled and said," It isn't the case, with your Unique Skills, you can cook food with a taste incapable of being replicated even with my abilities."

It cheered her up," Fufu! Then I will make some new dishes everyday", she said and I nodded with anticipation, finally we ate our food and I asked," Now do you have any opinions on how should we change this world? You see I have got an ability which can potentially change the Cosmolgy of the Universe."

They looked at me confused," Cosmology?", asked Ghislaine with a frown on her face and Minerva said," It means the very structure of the world, like how there was six worlds in past, dear can create higher or lower worlds, or separate worlds like Spirit World or he could empower our current world." Her words explained it and everyone looked at me baffled," Master is really Omnipotent God!", said Maria in an extreme fangirl tone.

" As expected of my lovely son", said Zenith with a grin, Minerva started explaining them further on the matter while I glanced at the Skill panel. It was basically Minerva's analysis of my Ultimate Skill.

Ultimate Skill: World Lord Zeon

World Creation: Master can create a separate time-space continuum and create a world, or edit the existing world. The world exists within the existence of the master in a complex multidimensional universe.

World Will Manipulation: Master can manipulate the world freely, included to it's timelines, space, and can even alter the basic laws or bend laws of fate, destiny and Karma.

Dimensional Layering: Master can layer the dimensions of his world, or create a barrier within any world, creating sub-worlds, these sub-worlds could be stronger or weaker than the main world.

World Core: The world exists because of the existence of master, and will cease to exist if Master wishes so, grants extreme strength within the world, included to Nigh-Omniscience, Nigh-Omnipresence, Nigh-Omnipotence.

World Energy Manipulation: Master can manipulate all the energies within the world freely, has extreme aptitude to even outside them, it is also possible to create a energy unique to the master's world's.

This Ultimate Skill was quite broken if I must say, compared to other World Skills which created a virtual world, this created an infinitely small Universe within my existence, of course it was due to complex dimensional layering and other factors, if I want I can release it outside and it will expand to a size of a Universe.

I was pretty much a God of this Universe, I could create worlds, destroy them, and do a lot more. I can also manipulate the time and space within the world and even alter the basic laws, like if I want fire to freeze than burn, then I can do so, of course almost everything will require energy. Which I can either use my own or the world's.

I could also bend higher concepts to a certain degree, like luck or destiny, to create a Protagonist who will basically have a high luck, though only limited to this world. Anyway, I started discussing with my wives on the topic after my Minerva has finished giving them an explanation. " I have an idea! How about we create a heaven!", Eris said cheerfully raising her hand.

" We must create a Hell for those who go against you", Lilia said bluntly in a chilly tone," Indeed your ideas are great despite being a bit cliche", I said, creating a Heaven and Hell was in my list. Of Course I won't be creating the general version of them. I pondered for a bit in my mind, and decided on what to do.

" Minerva you know my ideas, how should we proceed?", I asked my wife, Wisdom King herself, my hand put between her breasts, and her eyes looking at me with a serious expression was a bit cute. She was affectionate, but she made sure not to become extremely clingy as she knew I didn't like that. 

" I recommend creating a five layered world, we should create Heaven as a topmost divided into two layers, upper heaven and lower heaven, lower heaven housing the souls of the women who devoted themselves to the dear during life, they should be transformed into Angels using Purity King Metatron, and act as first defense of a layer of this world.", she said getting everyone's interest.

" Meanwhile Upper Heaven should house Dear, his wives, concubines and daughters. They will act as Godesses below us and manage the world. The Third layer should be mortal layer where all the mortals live, we could expand it as Universe containing multiple worlds, however dimensionally it should be the weakest, next we make a higher dimensional fourth layer which should be Hell", she said and stopped letting everyone take in her words.

" That's amazing!", said Zenith, Hilda and others nodded and she continued," Now we shouldn't make a typical hell, we will divide the hell into seven regions, where the souls of all the heretics will go, experience extreme spiritual pain under a distorted space-time continuum as they are broken into pure energy for the world. The last fifth layer should be an abyss which should act as a balance keeper", she finished.

As expected of her, she had thought out it well. I wasn't keen on expanding this Universe into something complex unless it needed it so, as I am planning to take the entire Tensura verse for me, thus this much of an arrangement was enough. Finally done with the deliberation and my wives being excited as they were going to become Goddesses.

It would be decreed in the teachings of our Sophia religion how some mortal women impressed me, the Supreme God, with their love and devotion becoming Goddesses, and our children being other Goddesses. This would be the origin of these Goddesses, though before we get to work upon it a question was present, what should I do Nanahoshi? 

I squinted my eyes as I looked at her and she shuddered," I- Please don't kill me!", she begged as she knelt, neither mine or my wives' focus had been much upon her, after all a lot of things happened and after her torture she preferred to stay away from wives remaining inconspicuous, I didn't forget her thoughts about how happy she was when she found I met a formidable enemy.

" Well, I guess I have a work for you then", I said with an evil smirk, she shuddered but kept silent and I said," I will tell you what you need to do later on, and if you disobey me, then I will kill you", I vanished leaving her, I quickly came outside in the previous Mushoku Tensei's Universe and finding Milkyway Galaxy, I devoured it and assimilated it in my Universe.

" Having a version of Earth to entertain myself would be surely wonderful", I muttered and Minerva appeared beside me," I have done with dimensional layering dear, should I separate the Milkyway Galaxy and Mushoku Tensei's Galaxy?", she asked me, and I nodded," Yup, otherwise it would ruin the fun of being other world, won't it?", she smiled and created a dimensional layer between the two galaxies."

We were done, and I could hardly wait to visit the Earth. We both teleported back to my Universe, leaving a crying Universe which has just lost one of it's most important worlds.
