It Started With Devils & Artefacts

"Hi" Regular Speech

'Hi' Thought

"(Hi)" Marcus's mechanically synthesised voice

[Hi] Aurora's notification

~~~~~~(SMUT INCOMING! Skip to 'In The Garage' if you wish to skip)~~~~~~

With a groan, Marcus opened his eyes. He looked at the ceiling for a moment before being distracted by a feeling that something was up, down there.

His gaze went down and saw that someone was under his bedsheets.

'Sera is getting naughtier by the day it would seem.' The teen inventor was 80% sure that it was Serafall who was down there.

But then again, the bulge in the sheets was too big for just one person.

So without wasting any more time, he pulled away the sheets.

His eyes slightly widened seeing who it was…

It was his pair of devil ladies! He was even more shocked at what they were wearing. It was a maid version of a bikini. And to add extra sexiness to it, they had thigh-high stockings with those fluffy thigh bands.

To top it up, the pair also had fake red horns on their heads…

"Good morning Master~~~ Happy Valentines day~~~ for today, we are going to be your sexy devil maids~~~" Serafall said with a lustful look as she, alongside Grayfia, were working on his pole.

Grayfia's hair was set completely loose. They looked like something along the lines of Yin and Yang; one is black-haired while the other is silver-haired. Even their eye colours fit quite a bit.

Now that Marcus was up, the devil girls didn't need to hold back and soon enough they started double teaming him. 

Licking from the balls to the top in quick succession. Switching between each other…

"Damn…"

The teen inventor groaned. This was the first time he was ever double-teamed like this. Especially by a pair of devil ladies! 

A few minutes into the play he came hard and the pair of devil maids drained him up greedily. Moaning and licking themselves up, this was just to turn their master on even more...

Serafall giggled for a bit as she enjoyed the face her Master was having. She turned him on quite a bit as even releasing his load he was still rearing to go for the next round.

This was what she and Grayfia wanted too.

"Well? Who do you want first~~~? Or should we decide for ourselves?" Serafall asked while putting her index finger on her chin. Looking quite sexy along the way.

"Hmm let's start with Grayfia, she received the least action," Marcus said to the pair as his hand stroked the leg of the silver-haired maid.

Grayfia nodded with a lustful smile before moving forward and sitting on her Master's lap. She moved her panties aside and positioned herself to insert her beloved Master's cock.

She softly moaned when she felt his rod sink into her wet folds. The beauty has been itching for this for the past couple of days. Just imagining her serving him like this made her horny and needy.

The moment it was fully inside of her she got into a proper position. Making sure her Master's eyes were on her, she moved her waist back and forth. Sitting properly on his lap, she was ready to start.

Moments later she started to move, starting slowly before picking up her speed.

Marcus' hands slowly went onto her hips, holding her. Not that it was needed as Grayfia was quite horny and was already on fire, fucking herself raw.

Going up and down with as much fervour as she could, this was just amazing as she remembered. His thing was touching all the right places and sending waves of pleasure throughout her body.

Serafall was looking at the situation with extreme interest, especially at how the infamous ice cube herself was behaving like a horny teenager girl getting fucked for the very first time.

Soon enough the maid lost herself as she enjoyed Marcus cock moving in and out of her slippery cunt. She was on cloud nine serving him like this.

Her hands moved onto her breast before removing the sexy maid bra, showing off her large tits which were going up and down according to Grayfia's movement.

Without even realising it, she came hard around his shaft...

"Ahhhh~~~~ so~~~good~~~" The silver-haired maid moaned with a glazed look.

Her whole body twitched and her back arched. She could not believe how seriously horny she was, to the point where came so quickly... Nonetheless, she kept moving her hips in rotation trying to milk her master as hard as possible.

"Heh~~~ you came so quick! As expected, the silent ones are always the lewd ones!" Serafall words snapped the beauty out of her blissful daze.

Grayfia blushed from embarrassment before moving off her Master's lap. She was reminded that she was not the only one serving her Master…

The black-haired beauty quickly moved in once Marcus's lap was free.

She turned and sat down on his lap in a reverse cowgirl position. The beauty made sure to look as enticing as possible. Leaning forward, pushing her panties aside and showing how her pussy was swallowing his shaft.

Mewing hotly in the process before starting to move her hips, going up and down with extra force. She was already quite turned on by seeing how Grayfia was fucking herself like that.

Soon enough a loud smacking noise started to spread through the room as Serafall was not holding back. Marcus just groaned from the pleasure the beauty was giving him. This was the best morning he had so far. It would seem that Solomon knew exactly what he was doing when he created Ars Goetia…

Devils girl are very good in bed, just like this.

The black-haired beauty, soon enough, started to change the way she moved. After all, she had already done this with her Master for quite a lot of time already. She knows which angle is best and how to ride him properly.

Before long the teen inventor could not hold it anymore. The black-haired beauty simply knew how to drain him and a moment later he released his load into Serafall awaiting womb.

"Ohh~~~ yes, here it is…" She moaned hotly as her body twitched for a bit when she felt the hot stream of seed flow into her.

She sat down properly on his lap moving her hips forward and back draining every last bit she could.

"Fufufufu~~~ you are still hard~~~"

The black-haired devil beauty said with a lewd look. She turned around and looked hotly at him.

"Yeah. It's Valentine's." Marcus said as his hands went onto her hips, stroking them for a bit.

"Indeed~~~"

~~~~~~In the Garage~~~~~~

Le Fay was aimlessly staring at the wall of her new room. She had just passed the tour of the 'garage'.

The blonde-haired girl has no idea why her Lord calls this place a garage when the things he creates here are already superior to any other pantheon in the world. 

This was better than Heaven in her eyes. A Magic generating core that produces perpetual energy? No one, NO ONE in the world, has created that! And yet, he can make those like paper! The assembly line was also another thing that is in the realm of miracles! 

If Marcus could, he can easily take over the world with that assembly line alone! It could produce anything as long as the design is sent to the main computer. Although, some settings need to be adjusted accordingly to what it's producing. Nonetheless! Even a four-year-old could create a bomb with this! It only needs a few presses of a button!

That's why she was just aimlessly staring at the wall. Her mind was still trying to process all of this! Perpetual energy is just a myth! it was before! It's even more mythological than anything the supernatural myth has produced.

Infinite energy is in truth, truly infinite! By her belief only Ophis, the Ouroboros Dragon God has achieved such a thing! But, this was not all. According to Grayfia Lucifuge, everything here runs on it or is based on it! So that means, the suit she saw, could technically exist until the planet is not around! His rifles are the same. The garage she is in right now will be around long after her death! It's utterly insane now that she was able to think!

She thought her Lord was amazing because he could use Solomon's magic but all that he achieved in 4 years? Is utterly insane! He took Solomon's magic and used it in such a way that it surpassed anything else found on this world!

Even Jeanne, who is mostly clueless about the true scale of things, was awed by the Diamond Core Hearts! Yes, Hearts, several of those are in use and it is simply overkill…

But, still…

'This is bad for my brother. No matter what he does, he will lose, one can't win against someone like Lord Marcus. Solomon's magic alone made the whole Devil kind drop onto their knees. And my new Lord used that magic to create a completely new plateau of power.

I need to find a way to tell him not to look for me. Otherwise, he will truly die against Lord Marcus.' 

Le Fay thought to herself with a sign before looking around. Her new room is, quite literally, just built. From the furniture, like the bed or the wardrobe, to the maid dresses hanging in said wardrobe. They are all brand new, just created from the very same perpetual energy.

It's absurd even by mages standards… Her Master could solve the majority of the people's crises. From shortage of food to energy issues, which still plague humanity as it is…

'Well for now I need to observe him and see who he truly is…' 

~~~

Around two weeks later, after Valentine's day, the information processing/storing facility was ready to begin the installation of the computer equipment.

It was built 20 kilometres Northwest to my birth town. In quite a large forest, deep underground. There are 7 floors in total,  a total of four Diamond Core Hearts will be powering the whole thing. Along with the assembly line and the robot maintenance facilities.

All in all, it is a fully self-sufficient complex that won't be needing any of my help. Though, I still go check things in person.

It is quite satisfying. The best part of this is the labour bots running it. I now have another Assembly line producing more labour robots to work on the railway.

I could have a much bigger assembly line complex, but those are going to be in the launching pad site and the Docks.

As it is, the current speed of progress is more than enough.

Now, I have started designing how the interior is going to be, how the processors are going to be spread out and such.

The best part of all this is that I can expand this further if I need to.

Quite a few kilometres in all directions.

Nothing too difficult as I had something similar in my past life, so It only took me a day to design the whole thing and the robots were finished with it in less than a week.

While the robots were working, I was also improving my workshop. The computer was gone, all that was left was my bent computer screen. The holographic table was removed altogether and was replaced by holographic projectors from the walls, ceiling and ground.

Nextly, I redesigned my main table for more comfort and efficiency since the computer itself was no longer needed. I now, most likely, have the biggest computer in the world, 20 kilometres away.

That's why when I noticed that quite a bit of hardware was online I started working on something quite important…

The next version of Aurora. My main OS has more than enough untouched raw processing power to tap into.

…

…

…

"And done…" with the last press of a button… the whole facility went dark. 

All the lights were turned off.

And slowly, one by one, everything started to restart.

"Umm is this...supposed to happen?" Jeanne asked me as she was, quite honestly, freaked out. After all, all the lights just suddenly went out. 

Le Fay next to her nodded as she looked around wearily.

"It should have happened as I just applied the update for the main operating system," I explained while looking at the screen, seeing all the systems rapidly restarting. The speed was… awe-inspiring…

After all was set and done, all the files, folders and windows opened, closed by themselves, leaving only the background image of Freedom Mark I facing Freedom Mark II.

"Aurora...are you there?" I asked with a curious tone. This was the moment of truth.

[Yes sir. Ready and waiting.] 

A smile crept on my face when I heard the voice of a female responding.

"Good. How are you functioning?" I asked  with further interest, this was the first time I am making a semi-magical A.I after all.

[All of the systems are ready and on standby. My programming has been done perfectly.] 

I nodded hearing that, I was expecting such an answer, I wouldn't just let Aurora restart without going through a bunch of checks up. Letting lose such a powerful A.I without any precaution is a very stupid thing to do. Especially an A.I that I made, which has access to all my systems.

That's the catch of this. Everything is operating on the same platform. For simplicity sake as well as an operational one.

"Good, how is the genetic scanning coming along?" I asked while leaning back.

Aurora quickly made a window appear on the screen, showing the percentage.

[9.46%]

[9.47%]

[Sir your gene decoding is progressing at a considerable rate, the speed is increasing with each new section coming online in the processing facility as we speak.]

[If the decoding progresses at the same speed as it is, it should be done by the end of today.]

My A.I answered with a certain and confident tone. I slowly nodded to myself.

So, 36 years of work will be done in less than 7 hours? Well, that is quite something else. 

And this was only with half the floors online. The new processors that I came up with are quite good. And I still have some more ideas to improve on them. With magic's help, some extreme chips can be created without any worry of them overheating.

~~~

While Marcus was thinking about his new A.I, the pair of maids who were in the workshop looked baffled after hearing a female voice coming out of the walls.

"This is an A.I! Our…Lord" Jeanne nearly slipped there. If Grayfia was here, she would have tried to find a way to dispose of the blond for the disrespect! "-has created an artificial intelligence! Do you know how cool that is!?" 

"Sorry… but I am more of a witch than a technology type of girl…" Le Fay replied with a nervous smile. She doesn't like being out of the loop like this.

"Well, simply put, his technology is so advanced that a computer is now like a person."

[Indeed. I am created with the sole purpose of serving my creator and in extension to assist with information for those who serve under my creator. Which means the both of you, and his Pillars who, at the moment, are out of reach.] 

Jeanne was with wide eyes when she heard the voice coming out of the wall and talking with her like this.

It was so sci-fi that she had a hard time processing what was happening.

"That's so cool! What else can you do?"

[That's a difficult question to answer. Your question should be more specific. For example, could I create a new branch of magic? The answer is, yes. Could I predict the future? The answer once again is yes. With my processing capacity, I could answer most of the questions regardless. The only diffrence is how fast I can answer said questions.] 

The more the A.I talked, the more the pair were impressed with how human-like she sounded. Nonetheless, the pair could sense some arrogance in her tone. 

Still, it was understandable, especially when the artificial intelligence has this many capacities.

"How much can we ask you? Since you said that you can provide us with information?" Le Fay asked with a thoughtful look. She was wondering if she could ask the A.I to send a message to her brother.

[I have several inbuilt monitoring systems which monitor the pair of you. This allows me to decide if what you are asking is something I should assist on or not. I do believe humans call it loyalty cards in those supermarkets. You earn these points through your work and deduct them when you ask certain questions above your 'pay grade'.]

"I see… so, it's not that easy then… how should we know if what we ask is above our 'pay grade' or not?" Le Fay asked curiously. She wonders if Aurora can help her with her magic studies.

[I can't assist you in your magic studies if that is what you are wondering. But anyways, for your question, I can easily help with any internet searches for information, or I can access my Master database and show the things that you have clearance on.] 

"Can we see our 'points' in a window screen format?" Jeanne asked after hearing about the points system.

[One moment. Creating…]

[Done]

Jeanne slightly raised her eyebrow, but before she could even say what she had in mind a holographic window appeared in front of her. 

[Name: Jeanne]

[Occupation: Maid]

[Loyalty points: 100]

'I am getting video games vibes from this! Nonetheless, this is so awesome!' 

The blonde excitedly checked the window. She slowly tried to press on the window, and to her small surprise the window was solid!

Seeing that it was solid she was able to gain more confidence in pressing on it. The first thing she did was to check the exchange list.

'Woah...I can get my own Scale mail!' She thought excitedly. 

Then she saw the price…

'1500 points!? And the mark II is 3000? How much do I earn per day!?' 

"How much do I earn per day!?" 

[Depends on how productive you are in a single day.]

Jeanne slowly nodded before continuing looking through the list once more. The rifles are in… the Blonde girl started counting the zeros in the window screen. She turned somewhat pale and excited seeing the description.

Pale that the weapon which was nearly used on her was classified as Anti-God level, capable of killing a god every two seconds or so. 

And excited because she could earn it. But pale once again because she doubts that she can even earn that much in her lifetime. The amount of zeros there are, is easily over 6…

Nonetheless, she saw that she can also use the assembly line. She can use it now if she wants. The problem is though...she needs a design… the assembly line usage costs only 10 points. But she needs a design to get anything from it.

Once again she went through the lists and she found that she can exchange her points for the designs and once again they were expensive. The rifle's design cost as much as the rifle, while the suit design however is cheaper. By a few hundred points…

'This is going to take a while…' She thought with a sigh. But she was now much more excited about the prospect of working. 

While, at the same time, Le Fay was going through the magic-related stuff. She was more or less confused by what she saw. Nothing here made sense to her. All she saw were systems… She knows what the M.T.M system is. And it is extremely expensive. She doubts she will be able to buy it at any time soon. But she wanted some sort of magical knowledge. And all she got were circles. And to her knowledge, to use a circle you have to use mathematical formulas. There were no formulas here. Only circles…

It's like the mathematical calculation was already done. But, this means she won't be able to just add them to her arsenal however she likes. It was like an already prepared food that only needs to be heated up before eating.

Which is something she doesn't like. What she wanted was the raw ingredients and the recipe… 

'I could buy one and try to decipher it…' 

She looked through the list once more and at the very end it was Solomon's negation magic which had a lot of zeros. It was very enticing. Something she would want to get, very much. In a way, it would be like a dream of a lifetime being fulfilled.

Nonetheless, she went up to the very top of the list and saw the overlapping circle. A circle that allows any other circles to overlap with each other. It only costs 50 points. Half of what she got. But the next circle was the acceleration circle and it cost 250 points.

And the moment  Le Fay pressed buy, a white tattoo appeared on her hand.

"Oh? You already used your points?" Jeanne saw the flash of light from her side as she looked at the girl next to her.

It would seem that the younger blonde already used her points for something.

"Yes. I want to study this magic." The younger blonde answered as she inspected the tattoo. She checked her holographic window to see if she could make more circles appear, since having just one on her hand was too little and she could lose it.

Thankfully, after buying it she can make more appear. Meaning, she can place as many as she wants. Allowing her to study this properly.

~~~~~~Marcus~~~~~~

When evening came, I was able to see a full decoding of my DNA.

It was something else…

I mean I can see my DNA just like this, and If I press on any of the pieces, Aurora would tell me what it is responsible for!

Firstly, I need to fix some of the issues. For example, by the time I was thirty in my last life I was bald, had some issues with my knees, and had problems with eyesight. The last one is for obvious reasons of spending too much time staring at a computer screen. 

And to do that I would need to either experiment with my DNA or get more data.

The first thing that came to mind though, was the three pairs of hair I got from the huntresses.

So, without wasting much time, I pulled out the specially prepared containers which hold the three containers for said three hairs.

My curiosity was at the absolute max to find out the differences between a Greek God and a human…

So, it was slightly shocking that Aurora was able to decipher Artemis DNA twice as fast as mine.

I was wondering why though. After all, the moment I could see her DNA, it had an extra strand of information attached to the regular two strands!

And I was able to figure out why it was so fast. DNA holds history as well. For example, the reason why I'm going to go bald is because my father, and his father before him were bald.

While the knee issues came from my mother's side, same with the slightly weaker eyesight.

Now with the Greek Gods… there is nothing of that sort of thing in Artemis. There is nothing 'inherited' from Leto or Zeus… in truth, there is nothing *human* in her.

She is extremely and biologically set into a specific standard. Her body is well fit, like someone who goes to the gym regularly. In other words, she is built to be a huntress, and body shape wise, she is built for action. Neither her breasts were too big nor too small. This most likely comes from the fact that she is a Moon Goddess and needs to be beautiful. Meaning, being beautiful was as important as having a body ready for action. Making her a woman who is very beautiful but still very much fit.

And yes, she is incredibly beautiful, I rebuilt her looks in my 3d display and safe to say, it was a mistake not to just take her home, tie her up, and leave her in my bed for daily play...

From the readings, I could understand that she is simply a dense amount of energy that took shape according to said divine energy… a divine energy that came from human beliefs.

While I could use Artemis' extreme biological setting; she can't get sick, doesn't age, and possesses quite the powerful regeneration.

But because she is an 'extreme', I can't copy this. Simply put, I will need a middle man to approach that extreme.

And for that, Hippolyta's DNA came into play. As a demi-god turned minor Goddess. The Amazon Queen was a treasure trove for me.

She is a blend of human and divine. Funny how the reading showed that she only had a single parent. As there is nothing of her father. Only some forceful configuration on her looks. Which probably comes from Ares. This shows that energies like the divine have some inference to genetics but can't be properly recorded since it's not natural to begin with.

Nonetheless, this was what I needed to get started on my upgrades. Receiving peak healthy condition, and no genetically bad traits. Is a good start.

While I could theoretically go through the huge upgrade from the very beginning it would most likely kill me, as my body would go through a massive shock.

"Aurora built me up a schedule for the upgrades and fixes."

[Of course, one moment.]

Moments later I could see a calendar pop up and the dates getting highlighted. 

I got a certain vibes from this… it was like one of those are the days I am going to visit the doctor 

[I do recommend specially prepared facilities for this sir. You need to rest after each session for several days. I recommend doing this in the Summer when there is no school. I could improve this further if more data is gathered.]

I nodded while listening to her. This does sound like it is going to hurt either way. And being too hasty is not something I want to repeat.

"Very well. I am going to gather more samples for reference." I said while pulling out Atalanta's hair.

"While you will continue to work on finding ways to apply the modifications as seamlessly as possible." 

[Obviously, I was created for this. There is no need for any reminders of such, sir. I exist to serve you. That will forever be my purpose.] 

I chuckled hearing that. She truly does take my designed personality well. Now I just need to think of an avatar for you.

~~~

Atalanta's DNA is something else. She was turned into a lion before being accepted by a furious Artemis for getting married.

Once she died as a lion she was turned back into a human. But, in the end, she still kept some of the characteristics of a lion.

Her senses are better in general, her DNA proves that. Her hearing, smell, eyesight, and muscle density are better than regular humans.

And this means that I could take some of these improvements myself without getting the characteristics of the animal. 

Now with four DNA stored I can cross-reference some things. Magic in general. Practising magic already alters your DNA to some extent. As my two strands have already started developing a third one. It could also be connected to how Artemis has a third one as dense as the other two, while Hippolyta, less so. And Atalanta only has some of it, assuming the characteristics of Lion made some alterations.

The stronger the being is, the more developed the third strand is… Well, that's what I got from all four DNA of four different beings altogether.

A Greek God, a demi-God, a demi-human, and a Human.

But, this is something I don't want to leave like this. So, I collected more samples over the next few days. My parents, and some random kids from school. With more regular human samples I was able to confirm what I had theorised.

Jeanne's and Le Fay's DNA only ironed it out, those girl's DNA are quite strange in the first place. Both of them had what looked like a genetic alterations of some sort.

I guess it's related to their backgrounds. Jeanne holds the spirit of the Saint Joan of Arc which, according to the girl, the holder always looks similar to the original saint. It most likely alters the DNA to make up the changes in appearance. While Le Fay most likely got hers from studying Morgana's stuff…

While these girls had some development in their third DNA strand, the same could not be said about regular people 

Neither my parents nor my schoolmates have even started developing the third strand. There are, however, signs of possible development.

This led me to discover which parts of the DNA are responsible for Magic development. Aurora was not even needed for this.

With this discovery alone, I could now rip magic off from people If I want to.

Targeting someone's specific Magic DNA sequences could cripple them forever. At worst, this could also affect someone else's future bloodline permanently as well. Meaning if I were to strip one's magic off them, I could also strip their future generations, forever.

Quite a horrifying thought. But a very much possible way to punish someone.

…

…

…

While sticking to genetics is fun and all. It's more or less Aurora's thing as she was doing most of the maths. So, I decided to check on Kuoh.

It has been over a year after all.

"Hmm…"

[Sona Sitri improved 47%]

[Rias Gremory improved 26%]

Well, well this is a surprise! Rias developed that much even before the events of canon?

Not bad…

Seeing as how Rias is training...well, training is a strong word. She is just doing regular exercises. And yoga… which is not bad. But, for her it is not that needed. What she really needs is some magic training. As she is a purely ranged fighter. While she is not lazy anymore, this kind of training is not going to secure victory against Riser.

Next, is Sona… Sera's sister is much better than the redhead. Her demonic power increased quite a bit. She has now recruited the majority of her old peerage from the novels and anime and is already regularly

Going through the data for a bit. I realised that the younger Sitri will be a good choice for more data. Not only that, but, she has the biggest selection of regular humans reincarnated as devils.

Their DNA is something that I would want to get my hands on.

And that's not all. The majority of them don't have Sacred Gears either. This means I could get double the amount of data just from her peerage.

"Plus… Sera needs some rewards for her hard work." 

Thinking for a bit, I decided that this might be killing three birds with one stone. Data, rewarding Sera, and also affecting Rias Gremory more, giving her an incentive to work harder.
