I was Reincarnated as the Youngest Child of a Villainous Noble Family Who Controls the Kingdom from Behind the Scenes

The man captured at the fort was handed over to the Kuroko (black-clad operatives).

Since his magical power was depleted and his clothes had been stripped off, he was effectively powerless.

As for that "thing," we made sure to thoroughly wash it in a nearby river, so there should be no issues.

Even so, the Kuroko, who usually move swiftly and efficiently, seemed a bit slower this time. Poor them.

Did he still smell a little, perhaps?

For people who usually handle corpses, they’re being quite sloppy.

That man will likely face interrogation at the Valphont family estate that will make him wish he were dead. Namu.

"Brother , is Miley-neechan here?"

"She was bragging about coming up with the idea for a slime sofa, so she’s probably here."

After leaving the post-fort cleanup to the Kuroko, we went to visit Miley-neechan’s magic research lab.

If we could get her to research summoning magic, it could become a weapon for the Valphont family.

By offering this as a bargaining chip to the royal family, our control over the system would become even more solid.

The magic research lab is located in a forest far from the royal capital.

Just as we finally arrived, I stepped back.

"Forest Chew——!"

"Yes, yes."

I deftly dodged my older sister, who fell headfirst from a tree.

This is straight-up horror. If it weren’t me, someone would’ve had a heart attack.

"Oww! That hurt... I hit my head. What if I got seriously hurt?"

"Normally, falling headfirst would kill you."

The fact that she’s unharmed after this stupidity is thanks to her absurdly enhanced magical power.

With her level of magical enhancement, she could probably take down a magical beast like Epsilon.

"M-Miley! Again——!"

"Lushiel -chan, should I do it too?"

"What are you——!"

This reaction is something she’ll probably be teased about for life.

I’m staying out of this one.

"Still, you should’ve made better use of the terrain."

"Enough with the pointless self-reflection. There’s a magic I want you to research."

"Magic? Is it more valuable than a slime sofa?"

"It is."

The trick is to let some things slide and keep the conversation moving, otherwise it’s impossible to keep up.

When Miley-neechan led us into the magic research lab, the hallway suddenly split in front of us.

And the hallways beyond that split even further, giving off a strong dungeon-like vibe.

Yes, Miley-neechan had turned the magic research lab into a dungeon.

Inside, magical creatures swarm everywhere, and they’ll attack on sight if you’re not careful.

You might wonder why she’d do such a thing, but if you start questioning that, you’d have to question everything she does.

In other words, it’s pointless to think about.

As for the other researchers—they arrived normally.

"Director Miley, who are your companions?"

"My beloved little brother, a stalker angel, and a muscle-bound magical creature."

"Hey."

"Hey."

"Hey."

We properly introduced ourselves because we didn’t want anyone to take her vulgar introduction seriously.

Even the World King shows more respect to Brother Vaid than Miley-neechan does.

"I see. Understood. Please follow me."

Miley-neechan and the researcher walked briskly ahead.

The hallways split unnecessarily, and there were multiple doors lined up. It’s impressive how much she’s transformed this place.

And what’s even more impressive is that the researchers know their way around.

"Ah, a Level 2 is coming."

What the researcher called a Level 2 was a magical creature.

The magical creatures roaming the lab were created by Miley-neechan.

She claimed it was for security, but most of it is just for fun.

I’ve never seen anyone toy with life like this.

"Haa!"

The wind magic unleashed by the researcher tore through the demi-human magical creature in one strike.

The researcher, adjusting their glasses with a flick of their finger while their lab coat fluttered, exuded an aura of strength.

Yes, even the researchers here had been magically enhanced by Miley-neechan.

"Miley-neechan is amazing. To make ordinary people this strong..."

"Making them stronger is easy. Just a bit of basics and some liquid."

She’s definitely making them drink something weird.

If you formed a unit with these researchers, they’d be more useful than the current knight order, but I’m staying out of this.

The researcher was about to open a door when they suddenly stopped.

"Ah, my mistake. This is the monster room... That was close to death."@@novelbin@@

"Having your life at risk just for opening the wrong door is insane."

Despite the situation, the researcher didn’t even flinch.

Probably, after being trained by Miley-neechan, their senses have become warped.

I’m not sure if that’s a good thing or not.

"Hey, what do you think of my sister?"

"I’m grateful. If it were the old me, I’d have been killed by that Level 2 we just encountered. But thanks to Director Miley, I now have the strength to protect what’s important."

"See, that’s my good side."

Don’t say that yourself. You’re ruining it.

Watching the researcher, it didn’t seem like they were just flattering Miley-neechan.

In fact, they were happily chatting with her.

"When I went back home, goblins attacked, but I killed them all."

"You’ve really improved. You could probably take down a Level 4 now."

"No way, a Level 4 is still too much."

Despite this dungeon feeling like something a middle schooler came up with, the researchers’ personal rooms are surprisingly well-equipped.

It seems the researchers are free to go home when they want.

At first glance, Miley-neechan’s actions seem chaotic, but they all end up benefiting someone.

Though she’s just doing it on a whim.

"Here we are. This is the lab."

Inside, many researchers were busy with various tasks.

Near what appeared to be a prototype slime sofa, captured slimes squirmed behind a transparent wall.

Using real slimes as materials is pretty hardcore. She’s completely insane.

"Director Miley, welcome back."

"Everyone, today we can conduct a new experiment. My little brother and big brother will help us."

"Oh! That’s reassuring!"

Wait, what? Why is a plan we know nothing about already in motion?

This isn’t reassuring at all.
