I Returned In The Past But Why It Look Different?! (Multiverse Fanfic)

Chapter 12: Chapter 11



Chapter 11

Right so, using the base of Castor & Pollux to make rifles is no go. So, the frame instantly goes out of the window.

The systems inside need to be expanded. First of all the M.T.M is expanded and made bigger and more circles are placed. Followed after that is the barrier rails.

They will be receiving the bigger upgrade of them all. First of all instead of two diamond rails, there will be six in total creating a hexagon shape for the barrel.

The rails will be connected by the barriers magic just like before. Now, however, the whole heat thing is meaningless because of the new frame.

It's magical, unlike the original so it doesn't heat up. No idea how it happening but assuming the whole molecule composition is different. And it's magical to begin with.

Nonetheless, the frame now is much bigger and thus I can add something more…

"Aurora access Balance Breaker relevant information and synthesize it. I want it simplified." 

[Understood.]

Notification popped on the screen which I brushed aside and returned to my design.

This time I will add Balance Breaker to the guns. For that, a core is needed. So, a small piece of diamond will be used. A miniature computer will be made for the gun.

The placing of it will be just above the trigger, below the M.M.B.R.S or Mass Magic Barrier Rail System. The hexagon-shaped barrel of the rifle. The revolver system was kept mostly the same as the switching speed was slightly improved. 

What's left is the Diamond Core of the gun to be added in the middle. Since the frame of the weapon will be the same as the sacred gears the magic flow will increase the overall durability of the weapon. Not only that the programming will help the weapon to rebuild itself. This function only work till the core Is broken which is quite a smart way to increase the overall durability.

"Hmm…"

My gaze went from the design to the computer screen. Aurora has sorted the balance breaker data.

'Hmm… so the high emotions generate excess magic. Because of lack of maintenance, the hold on the core of the gear is quite weak. This makes the core react which causes the mutation on the frame to accommodate the excess energy. This cause a side effect which is more power generated thus creating the so-called boost in the overall performance of the sacred gear holder.' 

After reading the overall report. I realised that this is quite easy…

The rifles will have a Diamond Core which generated a perpetual amount of energy. While the trigger of the gun runs on M.T.M… 

The rifles won't need the access energy to mutate…

In other words, I don't need to reach some sort of threshold in my strength, to achieve Balance Breaker, and certainly, I don't need to train to build up strength so that I could achieve this transformation.

All I need is to program the core to activate Balance Breaker and the rifles will transform.

And extremely easy programming. In the end, the blueprint and the design were done in a single day. I was even able to do the basics of programming for the rifles cores. 

Now all that was left is to send the order to the assembly line to assemble it.

Before I could do it though. A pair of hands wrapped around me from behind.

"You been sitting here whole day~~~ you need to rest~~~ Master~~~" The warm voice of Serafall entered my ear.

After the whole test flight, my little devil lady changed her approach. I didn't need to use my Ars Goetia to see through her.

It was obvious. She is a devil after all. One tactic doesn't work she will use another.

In truth, I don't care, as long as she stops with the whole reincarnation thing I am more than happy with her natural affection which doesn't have a hidden meaning.

"Quite on time. I was already done with." I said that while turning around. This made Serafall pull back for a moment. She waited for me to pull her back into my hands.

Before long she was back in lap cuddling for a few moments.

"Is this it?" She asked curiously as she looked at the rifle imagine on the designing table. As the moment the gun was in drawing stage. It doesn't quite need to get into 3d designing as rifle is not a new thing. And the basic math behind it was already done.

"A first Sacred Gear made by human. A perfect Longinus capable of killing Gods every 2 seconds." I said that with a satisfying smile as I pressed the mouse button and showed the Balance Breaker…

Something similar to the positron cannon wielded by Gundam Destiny.

Not only that but the Balance Breaker of the Rifles magnify the power of the cartridge stored in the rifle. That's not all. As I made the rifle capable of being loaded with three cartridges.

"...So, you did it! First-ever Sacred Gear build since after Biblical God!" Serafall said with wide eyes.

"Indeed. And unlike the original, this one has Balance Breaker built-in. The only thing that is needed to do it is a voice command." I said to her.

"I see… but, can anyone even carry a weapon with those capacities?" She asked with a little bit of fear in her voice.

"Not for regular being. The recoil will break the spine of a high-class devil regardless of how much of enchantment one will have." I said to her as I saved the design and closed the window before showing another one.

"With this, however, it will be possible to use it easily." I showed her the new arm designs for Freedom Mark II.

"...You already working on Mark II… you only few days ago did your test flight…" The devil lady in my hands said with a small amount of disbelief.

"You are not going to catch a break?" She asked with a small pout directed at me.

"I am taking one now," I said to her while smiling.

"Heh… very well then! Let's go to the kitchen I will cook something up for you!" She said that suddenly before getting up from my lap and pulling me up.

I chuckled amusingly before doing just that.

Well, I wasn't able to tell what kind of thing I came up to deal with recoil…

Since the material the suit is built off doesn't need to be extremely thick as it doesn't impact the durability that much.

So instead there will be layers of armour in between them there will be barriers of magic this is going to help with stuff like void of space or deep underwater. But most importantly I will be able to carve M.T.M runes…

Well more precisely Recoil to Magic so one can call it R.T.M system. The recoil will be transformed and sent into Energy wings which can be used either to enhance the flight capacities or increase the area of Solomon's technique.

In other words just from shooting beams, I will be able to increase the area of effect of Solomon's most broken power.

But for now, let's enjoy dinner done by one of the strongest female beings in the world.

~~~~~~

Serafall had a satisfied smile on her face. She was very much grateful that the one who ended up with Solomon's inheritance is Marcus instead of some horny brat like that Red Dragon Emperor.

Oh, she was watching him when she was not spending time with Marcus or Sona. That brat is the third person on her list. For the simple reason that she wants to see to whom he will end up.

Either her sister. Which is very doubtful or Sir-chan's baby sister which is most likely.

If this was before she meet Marcus then she would very much very interested in making this brat join her So-tan peerage regardless as So-tan would re-educate this brat. But now? The Red Dragon Emperor has dropped considerably in any sort of interest beyond casual curiosity. Even if the gear didn't go through the maintenance. It wasn't as impressive as what her beloved Master could do.

It took him only a day to design a super devil level weapon. Well, yeah, the technologies and systems before took some time to do. But once they were done he only needed a day to draw it up.

Still, all that is good and… terrifying what she truly likes about the situation she is in right now is that her master was a teen and she just offered herself as a 'snack'... But, what did her Master do? Pulled her into a bed and make her into a hug pillow and decided to call it a day.

This was probably the biggest 'loss' in her life. Not battle wise or anything like that. More like in her devil charm and seductiveness. Yet, even after experiencing such 'loss' she only wanted to cuddle herself with him more. Most likely she just fell in love with him more.

Nonetheless, her new approach to her Master did work. Even though she had to go through a series of questionings, since Marcus instantly noticed her personality change. It was a reminder to her that her Master did not easily fall to her charms

So, after the questioning, he became much more satisfied with her. Serafall understood that if she wants to get her master's help. First and utmost she has to think about her Master as a priority. This way he will be more inclined to help the devils himself since he cares about her in turn...

It was weird when she got this advice from Grayfia of all people, who she used to believe is nothing more than a cube of ice.

~~~

When Marcus finished his new rifles he wanted to test them out at max capacity… the problem was he can't test them anywhere near his garage or even in his birth country.

As each blast generates as big of a blast as a hydrogen bomb.

This means he has to get to a location where he can test this without outsiders finding out what is happening.

While he originally intended to go to the South pole Serafall offered a better solution to this.

Creating a dimension. The rating games create dimensions for devils to observe. But in this case, he has two top female devils under him.

So, creating an area to test his rifles was not an issue anymore. Now the issue was if this dimension can hold without bursting under the weight of the explosions.

After thinking for a bit he came with a solution for this. Diamond Core Heart. Several of those.

One for stability of the dimension, one for the ground, and one for barriers.

"You know…" Serafall slightly gulped down seeing three Diamond Core Hearts which Marcus just pulled out from his inventory ring.

"One can protect a Pantheon… you pulled out three… you do realise that's like using a hammer to kill an ant?" The Leviathan asked him with a sweaty forehead. She remembered that his assembly line can make those like a printer…

"Hmm? This is to make sure we have a comfortable time testing the rifles." He said that casually as he started setting up the cores.

Serafall just looked at Grayfia and Venelana in disbelief. Her understanding of reality started to get warped more and more with each new project created by her Master.

And this situation just highlights it. One core is enough to hold back an army of powerful beings. With two he could easily make a fortress worthy even of the greatest pantheons… 

And with three? Well, she can't even fathom…

Just a few minutes later the reality was brimming with magic. Magic flowing in the ground. Through the very fabric of this dimension.

If this was a cultivation reality then this place would be the apex place for cultivation.

Instead, it will be a shooting range for Marcus rifles.

Laying down the barrier in a specific way that they would hold the explosion in a controlled manner. The teen inventor was ready to go.

For this he was dressed in Mark I with upgraded hand armours and the energy wings for this test.

Marcus lifted his right hand and looked at his rifle. It was a silver rifle with a hexagon-shaped barrel. If one could look at the barrel insides they could see a magic circle slowly spinning inside of it. 

And they will be spinning for a very very long time. The rifle itself looked like from a sci-fi flick, a combination of magic and technology.

"Let's start with P.O.D beam." He said that while lifting and targeting the rifle.

The way he was holding looked extreme casual even...showing off.

Then he pressed the trigger and Serafall could see his boots slightly getting pushed back… sinking into the ground... apart from that there is no other visible discomfort, the hand didn't bend backwards or anything. It's like the recoil was absorbed and sent through his body into the ground. 

At least that's what Serafall saw.

And the beam itself while not being destructive since it's a beam it did however erase a multitude of barriers that were powered by the Diamond Core Heart.

And...from her instinctive side of things, she knew that she would be dead if that beam is to hit her…

Most likely there won't be anything left of her a pure and clean erase.

Truly a horrifying weapon. All her years of training are meaningless in front of a tool created over a single day.

"Well. It would seem the beam indeed has enough power to instantly kill at least five Ultimate Class beings without any resistance. The barriers could not even hold it for a second.

It went cleanly through it." Marcus said that as he lowered one of the rifles. He then switched his position and lifted his left hand. This time the barrel of the weapon slightly widened.

This was something new at least from Serafall perspective. The Leviathan never saw that one of her Master weapons creates the cannonball in the barrel instead of outside of it.

But this one… it moulds already created cannonball further after manifestation before realising it…

'Just how many stages it goes through before shooting it?' The black-haired Devil lady thought about this curiously. Only the other two just looked at this differently.

Venelana was just speechless while Grayfia didn't care much. Only that it's her Master's brand new and very destructive weapon… what about it?

While the beam could not truly show the sheer raw power of the rifle the cannon was completely different in that regard.

The moment the ball of black energy with deep red coloured core left the barrel white-ish barrier surrounded the spectating devil ladies as the ball's force instantly broke the sound barrier and nearly warped the space.

One moment it was at the edge of the rifle the next it was already on the other side of the shooting range ramming into a target created by barriers.

What happened next made everyone except Marcus deaf for a moment, as all sound was killed in the area and as the shooting range transformed into pitch-black darkness with wisps of red.

From the looks of it, the barriers could barely hold the explosion inside of it.

The pair of strongest devil females needed... barriers to protect them from the initial release of the P.O.D shaped in a form of a ball.

That just shows how lethal the cannonball was before it could even hit its target!

"..."

"..."

"..."

"This... how is that possible!? How the rifle is still intact after releasing so much power!!!" Venelana asked after regaining her hearing, there was complete disbelief all over her face she just witnessed something for sure would be able to kill her son!

Maybe not one of the blasts but the next one for sure! Simply because of how rapidly it could shoot again! There is no reload. There is no time lag! Nothing!

This was simply...absurd!

"The rifle has two completely separated magic energy eco-systems inside of it. The M.T.M is still there. While the weapon frame itself is powered by a separate perpetual energy system. This makes my Sacred Gear powerful and even eternal time-wise." Marcus explained to her as lowered his left rifle and once again switched to the right one. This time he released a casual bolt of energy…

It should have been casual but, the explosion once again darkened the shooting range…

Thankfully their ears have been spared from another moment of deaf.

"This… how is that even possible? The energy needed for that…"

"It's called perpetual energy for reason. I don't need to care about energy. Only how to pull a large amount of. Energy is never been an issue." Marcus casually explained to her as he started testing the scattered shoot…

And once again it should have been casual… but these golf size balls of P.O.D could erase something like New York into rubble. 

"This is bullshit…" Venelana could control herself anymore and swore under her breath. Both Serafall and Grayfia looked with shock at the brown-haired woman. Who probably never swore in her life.

In public that is…

"My son spend decades training his power to reach this level. He is the strongest devil living at the moment and he can only demonstrate this kind of power by transforming! But all you do is press the trigger!" The devil lady said with that with annoyance. 

"Impressive," Marcus said that simply. As if they are discussing the weather forecast.

"Impressive that someone can achieve that through training. I guess I need to try harder if there are being like that." 

Venelana opened her mouth from shock hearing that. She realised that she might just make her Master try harder to make even more crazier stuff!!!

"No-no-no!" She quickly shook her head and hands in front of her. For a moment she looked like a panicked teenage girl.

"I mean what you achieved in such a short time is simply astounding! That's what I am saying! My son spends an incredible amount of time training and did that in such a short time! There is no comparison!" By this point, Lady Gremory was buttering up and trying to flatter her Master as much as possible. Like hell she wants him to create something which could crack the planet by accident or something like that!

"Obviously. Your son trained his magic to achieve that level. But, where he build a castle from things he finds. I brough materials to build mine. Where he build it by hand. I build it with instruments I created myself. I did what humans do best.

I simply found a way to build it faster, easier, more efficient, while his hard work is impressive he spend alot of time doing that. That's all there is Venelana. He is a fighter and I am the inventor and engineer. I invent while he fights.

Comparing us is pointless. You should compare engineer to engineer, fighter to fighter. I will never going to fight with some warrior's honour. That is for warriors to do. More specifically I won't even going to fight… I will simply disable the enemy and take him to the lab to research him, that's if he has something to research. If it's a most boring enemy I will most likely…" Marcus lifted his rifle and shot a bolt of energy at the target.

Once again the shooting range turned pitch dark. Venelana got the message loud and clear. Borderline getting deaf again.

~~~

"Sera… do supernatural world has something similar to bounty hunting?" I asked the beauty next to me as we watched Mark II getting assembled.

The robotics hands were swiftly working transmutation creating the metal while other sets of robotics hands were drawing runes and magic circles at rapid speed and insane precision to regular person.

The black-haired girl next to me wanted to see the magic behind the hood. So, I brough her to the assembly line downstairs to see how Aurora does her magic.

"...Nothing of that sort exist… but, we have a list of people which other pantheons don't like and want to make them disappear.

As you can imagine no God will lower himself to go on manhunt just because some human crossed one of them. No, they either smite one before he leaves the Pantheon controlled territory or simply notify of other Pantheon about the specific person. As you can imagine that kind of people become something akin to terrorists in the mundane world."

"Meaning that they won't be missed…" 

Serafall instantly understood what I meant.

"You wish to hunt them? I see… you want 'interesting' people… I assume you don't mind doing this for devils first right?" 

*Snort*

"I only care that I get something Serafall. If the person has interesting gear I will deal with it and I will keep the gear for myself. If this benefit the devil kind then it's even better…

After all...one man's trash is another one's treasure… who knows maybe that person will help everyone by dying and me getting his gear leading to some nice invention." 

I said with a shrug as I watched the helmet taking shape. Freedom like always looks amazing...especially when it is real and functioning.

"I see… so, you don't mind getting used?"

"Your way of thinking is wrong. I am not getting used. I am quite frankly stealing what was your race's beforehand. It's something along the lines of acquiring an item that belonged to you but I am keeping it to myself in the end.

And the best part in all of this is that will get my precious 'battle' data." The way I mocked word battle was not missed by Serafall.

In the end, I did mock since there is no such thing as battle. According to my calculations, only a God-King level being could do something to me for the first 3 minutes before I erase him.

That is if my prediction curve of strength is what Serafall is telling me…

And of course… God-Kings don't just walk randomly around…

"I see… the way you put it makes us look bad for losing our assets…" She sighed with a resigned tone.

"Very well. I will compile a list of wanted and 'interesting' people." She said that with a nod, before continuing to watch the assembly now with a thoughtful look.

~~~

While Serafall was doing her thing my Scale mail was ready as well as weapons. While test flight was not needed… well I did it anyway… nonetheless the news layer design allowed me to reach speeds beyond Match 5 the jet lag was cut by more than half.

While this is great and all, I can only do it in a straight line only otherwise it will rattle me quite a bit.

This pushed me to delve into something new… genetics…

With help of Grayfia and Venenala, I quickly got a mountain of books on that subject…

The moment I saw them. I realised that it's big… genetics is a very big branch of biology.

While I knew before that it's big...Now I saw the big picture… 

And yeah, quickly started reading through it. This was my first time studying after my reincarnation before this I only revised some things...like robotics, while Freedom is a scale mail not truly a robot I went into servo motors and joints functioning.

To increase the punching, lifting and running force. With magic help the force behinds those becomes much bigger. 

Nonetheless, it was nothing more than a light read compared to this.

Before can I get into this properly, I received the hit book from Serafall.

First I checked out if I know anyone from the books or the show. I do remember there was Khaos Brigade or something?

'A cheap naming rip off from Mortal Kombat but, they were proper terrorists with alot of interesting people. Originally supposedly led by Infinity Dragon. A Dragon God which likes to look like a small girl… well, until she halved… infinity halving… I have no idea how that is possible…'

For a moment I thought about this nonsense about halving a being of concept. The only thing I can think off that she lost some power over infinity. Meaning that curse made her lose control over specific power. If this is true then I could do that to a bunch of annoying beings and make them lose power over their concepts.

'Well, I can check this later now… some manhunt…'

My eyes landed on the first pictures of the possible targets...

'Well, well, Serafall is not holding back on her 'requests' first people are the old Satan faction…' 

'Hmm...their powers and abilities are not that interesting and they have no Sacred Gears obviously…' After checking those I went over to the next page…

Checking the targets and moving on…

Eventually arriving and something fascinating…

'And what do we have here… Cao Cao… the descendant of the original Cao Cao. The one who has the True Longinus…

Heh… wanted by The Church and by extent the Heaven for the Spear.

Isn't it kind of amusing how Heaven remain 'pure' while the Church does all the dirty deads of Heaven? This way if they get caught red-handed they can always blame the church for acting out of the line.

So, sneaky and so outdated… or it's just me? Anyway, we can leave Cao Cao for later, knowing him he does what his ancestor did…

Collecting talent… or in this case humans with Sacred Gears.

For this I need more info for him. If he has his Hero Band of his then I will swoop in until then I shall collect the stranglers.'

My gaze ended up on a stray devil lurking in Siberia… 

He has that interesting and quite common gear with the name Sword Birth.

The creation of Demonic Sword. Not going to lie, this is nothing more than confirmation. I already have several theories on how these 'incredible' swords are done.

So, this hunt for the stray is nothing more than to find the truth and make Sera find a little bit more on Cao Cao…

~~~~~~Siberia~~~~~~

'Shit-Shit-Shit! Who the fuck is that guy!?' A man which looked in his twenties was running through the thick snowy forest, his speed was considered supernatural as he would leave something akin to a sonic boom each time he accelerated.

Showing that he could break the sound barrier with nothing but his natural speed alone.

Not that it mattered in this situation as he would occasionally turn around and look at the sky. There was something akin to a white star there following him.

'What's with that freaky armour! I can't feel shit from him!'

"Are you ready to tell me how you fought back the mutation of your evil piece?" A voice asked him from somewhere.

"Fuck off!!!"

Once again he started sprinting away.

"...Crass… very well then, there are other ways to figure that out…" 

The guy felt a chill running down his back as he heard multiple claps of thunder followed by multiple balls of electricity starting to rain down from heaven.

"Hahaha! Your aim is shi-" The guy wasn't able to finish the sentence as a ball of electricity slammed into him with force powerful enough to send him flying…

Breaking several trees in the process, the reincarnated devil ended up laying on his back…

That moment he realised that his body is disabled, the amount of electricity rammed into him was able to fry his nerves but not strong enough to outright kill him! Such precision in energy control was absurd even in supernatural circles.

Moments later the armour landed right in front of him and the rifle's barrel was pointed at his head.

"I do thank you for allowing me to test at shooting moving targets." 

'Fuck… he was missing on purpose! Fuck this freak for messing with me!!!' 

"Good night. Pick a realm of dead of your choice… oh, wait! Devils don't go there… my bad…." 

The next thing he knew was more electricity which fried his brain ending killing the stray devil.

Once the death was confirmed several white circles surrounded the body and moments later something came out of the body in the shape of a translucent orb with a sword inside.

This was the Sacred Gear Demonic Sword Creation or known as Sword Birth to the rest of the world. Quite common gear. And very much so common around the Devil circles.

A few moments later the orb was collected and the dead body was erased with a single blast of the rifle.

The energy wings glowed and the armour started floating again.

"Hmm? Company? An interesting method of hiding magic. It's not bad. But, for someone who has magic vision, I can see the trails of magic…" 

To his words, figures started coming out from behinds the trees. They all were dressed in white fur-like clothes with hoods. But, they all had one thing in common… and that is silver bows with arrows.

The one figure leading the front was the most unique. While looking identical to the rest in clothes the aura she had was different. It was almost like... divine.

"Who are you? This area at this time of the year is used by my hunt." The woman asked with quite an authoritative voice. The only reason she didn't open fire at the person in the armour was because she can't tell who it is…

This was the first time in her very long life that she meet someone which she can't discern at all! It's like all her divine power just bounces off from him. She can't tell if it's male or female!

~~~~~~~~~Inventions/Tech/Sacred Gears~~~~~~~~~~~~

Freedom Scale Mail MK II

The Battle version of Scale Mail armour which was built by Marcus. It was created by using both magical means as well as technical means to create the perfect blend of both.

Classification: Pseudo- Longinus Sacred Gear

Composition: Sacred Gear alchemical metal, Diamond, transmuted electronics, plastic, rubber.

Key magic system and technology:

Exoskeleton system: A support system to control the scale mail. It reads users movements and thoughts and assist the user in controlling the Scale Mail.

Aurora Battle Assistance OS: The scale mail runs on Aurora OS and is connected to the main Database in Marcus Garage. The Battle Assistance software runs alongside the main OS. This software analyses and offers the best possible course of action to deal with the enemy.

G-Force Max Support: A System designed to mitigate the G-Force which scale mail is exposed to when flying at high speeds.

The newly upgraded system has countless small barriers spread inside through the whole body of the armour. 

As a side effect of this none of the outside beings can sense who is inside the armour.

Diamond Triangle Core: Modified version of Diamond Core Heart based for Scale Mails. It's used as a main power source for the Scale Mail and is independent from the users energy source.

Crystallised Energy Flight Support (or C.E.F.S for short): Magic energy crystallized in form of wings. It gives unprecedented ability to fly. 

Solomon's Negation Magic Support System (or S.N.M.S.S for short): Specific type of energy is dispersed through the energy wings which affects other types of energies in the area of effect(AOE) type of fashion 

Recoil To Magic (or R.T.M for short) Is a branch magic system used in the arms of the scale mail. This system is directly connected to the energy wings which release uses the newly created excess magic.

~~~~~~~~~~~~~~

Deimos & Phobos 

The twin rifles and spiritual successors to Castor & Pollux guns. These are the first true sacred gear built by a human.

Classification: New type Sacred Gear, equal if not superior to original Longinus gears as it has natural Balance Breaker, as well as much more durable than any other gear created beforehand.

Composition: Transmuted Sacred Gear metal, diamonds.

Balance Breaker: The Star of God of War

The rifles merge into form a single-particle canon 

Key magic system and technology:

Motion to Magic (Rifle version): The system has been reworked and perfected for the use in form of a rifle.

Mass Magic Barrier Rail System (Or M.M.B.R.S for short): The next generation Barrier Rail system. Instead of using just two rails, this system uses 6 in total in the shape of a hexagon there are multiple magic circles in the rail path which help shape the 'cannonball' in case of the canon version of the shooting.

Revolver System v2: The reworked system to switch the type of shoot with faster speed.

Triple Cartridges Loader: Instead of being loaded with a single type of cartridge Deimos & Phobos are loaded with three. This way the switching could be minimal.

Aurora Sacred Gear Core: The cores of rifles are fitted with mini-computers which is responsible for the systems and is the key to unleashing the Balance Breaker. As well as recording the data to further improve the rifles, the weapons are always connected to the wider network thus allowing constant monitoring.
