(MC POV)
I was guided by the hand by Odriana and Elaria, both of them leading through a small passageway that connected my forr bedroom to what they dubbed 'The Workshop'.
??
The passageway had been hidden behind the largest painting that had covered an entire section of a wall back in the room.
I am quite ashad to report that it was a painting of a younger wearing an unbuttoned dress shirt and pants, revealing an exaggerated set of abs underneath the shirt. I definitely did not look like that when I was at that depicted age.
I had mixed feelings when my younger sister had skipped towards the drawing of and started pressing the abs in a pattern, causing a section of the wall near her to open outwards.
Odriana then ushered through the hidden door, guiding down a spiral staircase with Elaria following closely behind.
Fluorescent lights blinked on when the wall closed shut behind us, illuminating a long passageway ahead of .
With Elaria holding on to my left hand and Odriana my right, I was half-dragged, half-carried towards their destination.
"You'll love it Onii-sama! Maybe after seeing everything you'll finally rember!" My little sister declared cheerily.
I really doubt it will be that convenient but I wasn't going to tell her that.
But still… This whole corridor was rather unnerving and I'm already ignoring the fact that fluorescent lamps were inventions way beyond the Renaissance age.
Sothing tells my little sister's scope of operations has been much bigger than I had initially thought...
The passageway ended at an unassuming brick wall, its look similar to the rest of the corridor that we were in.
I looked back to see if we might have missed a turn sowhere but there were no gaps in the walls as far as I could tell.
My little sister skipped towards the wall, pulling out one of the bricks to reveal it as a fake cover for a keyhole behind it.
My elder sister sauntered towards the opposite side of the wall at the sa ti, mimicking Elaria's actions except her side had two levers instead of a keyhole.
Pulling out a key from between her bosom, Elaria stuck the key into the hole and twisted it clockwise.
She glanced towards my Elder sister, "Pull the lever, Kro--Onee-sama!"
Odriana pulled one of the levers down.
Whatever I had expected the lever to do, a tal cage dropping down from the ceiling above was not one of them.
I barely managed to roll out of the way when the trap crashed down at where I had been, missing by a re hairsbreadth. If it wasn't for my current smaller stature, it would have most likely caught inside.
"Wrong lever!" My younger sister yelled indignantly, fussing over to check if I was hurt.
"Oh dear… My deepest apologies," My elder sister apologised, pulling the correct lever this ti.
There was a soft click and the brick wall in front of us pulled back and away before sliding out of sight.
Compared to the dirt ground of the passageway, the floor behind this hidden door looked tallic and smooth.
The clanking sound it produced when I stepped on it confird its tallic properties.
I had no ti to inspect the ground any further as I was busy marvelling at the contents of the giant room in front of .
Did I say giant? I ant humongous. Like, I'm pretty sure this entire underground complex took up the underground space of the entire town in fact.
The room was painted pure white, the walls and floors made up of individual white tallic tiles for what I assud to allow for better maintenance.
Within was a vast array of electronics and machinery, all of them looking rather crude and ugly though I'd wager that's more because the creator focused more on functionality than making them look pretty.
There was a low humming noise from a big machine in the corner which I could only assu was the generator for this room. How it was made and what it was running on I have no idea.
Wires were connected from it to various machinery in the room, so I recognised and so I didn't.
I pointed to one of the biggest machines in the corner of the room, "Is that… A computer?"
Elaria nodded her head enthusiastically, "As expected of Onii-sama! Sugoi! Your mories are returning right?! I based that thing's design off the ENIAC that you showed before!"
I most definitely do not rember showing her anything like that. I only guessed what it was since I saw the wires, blinking lights and what looked like a very rudintary form of a circuit board.
"What is that generator running on then?" I asked.
This ti it was my elder sister who answered while patting my head, "Fufufu~ Allow your big sister to explain this one my dear little brother. I'm sure everyone knows that monsters are a nace to everything in this world, yes?"
I shook her hand off my head, "Don't tell it's as convenient as there being monster cores acting as power sources."
"Oh? Has dear little brother already looked into the Monster Crystals' usage? I expected no less of you, fufufu~"
No, it's because that's the standard for most settings isn't it? It's also the most convenient as well. Put monsters in the world and have them grow cores or sothing inside their bodies which can be conveniently used as renewable energy sources.
I'd think if humanity really found out about this, they'd already be hunted to extinction within the year.
"Ehehehe~" Elaria giggled. "I spent a good full year to understand the characteristics of the Monster Crystals, but it was all thanks to Onii-sama giving an idea of other worlds that use them that I can think of such a thing so quickly!"
So it's still because of huh?
She pulled towards one of the machines where the corpse of a wolf type monster was laying. The whole setup looked like so sort of butcher's chopping board except it was more grueso with all the blood-soaked dical tools lying around.
Elaria hopped happily to the table, picking up one of the knives in her hand, "You're just in ti Onii-sama! I left this one around to experint on since the 'An Ney May' Labour division would handle tasks like these. But here! Let show you!"
Experints? I must have heard wrong right?
I watched as my little sister plunged the knife into the belly of the corpse without hesitation, cutting it open in one smooth motion.
Holding the incision open with one hand, she plunged her dainty little hand into the corpse, digging through it for a bit before pulling a fist sized, black coloured crystal out. She was entirely unperturbed by the blood drenching her entire arm.
She crouched down and presented the fist sized crystal to proudly, "Look, look! Elental Quarks solidifies within monsters to beco crystals a few days after their death! After cleaning and processing it, we can use it for power! The bigger the monster, the bigger the crystal! One that is of this size can power a house for a day right now, if only I can improve on the refining process it'll make it last much longer."
I am hesitant to even ask how many corpses she had to go through to refine this process.
Not to ntion the fact that usually monsters that are killed would simply be used as food and materials or imdiately disposed of to avoid attracting other monsters, probably explains why these 'Monster Crystals' haven't been found by anyone else yet.
"That's good and all…" I said, pushing her bloody hand away with a finger. "I assu you've released every new technology so far out to the public?"
Odriana chuckled, "Oh my dearest little brother really knows how to make jokes! Of course not! We reserve the best ones for ourselves while dribbling the outdated ones to the others and selling them at sky high prices. Once we drain out the nobles and the rich folk, we'll be able to establish ourselves as the head of any future endeavors without competition!"
I looked up at my elder sister with narrowed eyes, "I don't suppose you'll also be making the people reliant on your company's goods to gather support from the masses so no other business can touch you?"
"Ufufufu~ As expected of my most adorable brother to figure all this out! Totally unlike that dumb Dailus who fell right for our sche to take over the family business~ In fact, we've already achieved that part of the plan already!"
This is beyond frightening…
A little sister that is a genius scientist with little to no morals coupled with an elder sister that is rciless in business… I fear for the future of this world.
