The advantage of banging is that it''s absolutely exhilarating, but the downside is that it''s so exhilarating that you get completely absorbed.

Even when your body’s tired,

even when you feel like you’re about to collapse, there''s a momentum that keeps you going.

Especially if the woman you''re with is stunningly beautiful? Then, no words are needed. You just spread her legs and go for it.

That''s how it was between Go Min-young and me. It was like playing house as newlyweds; even if we paused for a moment, just a glance would set us off again, grabbing each other and inevitably pressing our bodies together.

But we couldn’t keep doing it indefinitely.

So, around evening, with some reluctance, my aunt and I headed for the bathroom. And, well, we did it once more there, but anyway, now we’re out, fully cleaned up.

"It''s been a while, you two." "...Master, you look like you''ve lost some weight?" "My lord, what on earth happened...."

Soo-ah and Baek Seol, whom I hadn’t seen in a while, looked at me with concern. And no wonder, as it’s currently about 6 p.m. on a Saturday.

It''s hard to believe, even as I say it, but that means I spent nearly 18 hours straight having sex. Without even sleeping...!

Naturally, I feel like death right now; my groin aches, and the moment I let my guard down, my eyes start to close. If I got in a car, I’d probably knock out right away. It must show, too. My dark circles are hanging low, and I look like I might fall over if you so much as poke me.

Meanwhile, my aunt is putting on a calm, unbothered expression, like a true iron-willed person. How can she even manage that? Did she take some kind of powerful recovery drug? Thinking back to that time when I caught the flu and instantly recovered with one shot, maybe something like that exists.

"But I can''t just inject anything into this body that’s been clean from drugs...."

"...I kind of guessed from the rose, but still."

Soo-ah seemed to assume I’d been in some kind of fiery, passionate encounter. Well, it’s only natural. A man and a woman go into a room and don’t come out for 18 hours—what else would anyone think happened?

“Do you think the rose’s effect is really that strong?” “I mean, it must be? Even if it’s her nephew, with that kind of rose, anyone would be tempted...” “I see.”

If the effect is enough to make aunt-and-nephew relations plausible, just how powerful is this item?

"After all, the rose’s meaning is ‘I love you.’ So, if you give a single rose burning with that kind of intense passion, what else could it mean....” “Wait, the rose has that meaning?” “...You didn’t know when you gave it?”

...Damn it.

Did I actually confess to my aunt?

"A single rose means ‘I love you.’” “Oh my.”

If a single rose means "I love you," then would a burning rose mean, "I love you intensely"? And if it’s a rose that burns forever?

“I love you intensely. Forever?”

“Wow.”

I really went overboard.

Not only did I confess, but I gave her the item “Undying Enchantment”? No wonder she was so completely into it....

“So that’s why she was so wet and craving me....”

Now I finally get it.

But then, what’s with her hymen? Why would my aunt have a hymen.... The rose can’t possibly have that kind of function, can it?

"Damn, I want to ask.”

I''m insanely curious, but sadly, this isn’t the time. I should have asked earlier, but I was so busy having sex that I never got the chance. Now, I can’t just suddenly say, "But why do you have a hymen?" out of nowhere.

"I''ll have to find a chance to ask later. Somehow."

“Nephew.”

Just as I was thinking about it, my aunt called out to me.

“Yes, Aunt.” “Since we’re ready, let’s go.”

It was time to receive Baek Seol’s exclusive weapon.

+++

I have a rather grand plan in mind. Once I get Baek Seol''s exclusive weapon and secure the artificial island, I’m thinking of touring the headquarters, strengthening our Soo-ah, and looking into weapons and reinforced suits that suit me.

If possible, I’d like to acquire about ten suits for general use as well. It’ll be expensive, but with that much, I should be able to hold my own wherever I go.

Ah.... Our Seol is just that powerful.... It makes sense. She’s destined to become humanity’s strongest knight.

“It seems... somewhat decent.” “Our Seol is pretty impressive.”

I can’t help but feel proud. But does this mean I practically conned my aunt out of over a trillion? I still need to get the artificial island and my own rig—this feels like I’m asking for too much.

“Wow, that little thing costs a trillion....”

Soo-ah drooled over it. Why is she so eager? She’s not even a knight. You can’t use it anyway, girl.

+++

The next thing we looked at after the exclusive weapon was the mecha.

It’s Baek Seol’s personal rig, currently under construction, but it’s in such an early stage that the shape isn’t even clear. All I could see was something being hammered away in the distance.

What impressed me more was the vast underground space I’d seen earlier—a massive cavern capable of holding an entire city, with every conceivable weapon neatly stacked inside.

There seemed to be nearly a thousand mechas, the most powerful modern weaponry in existence, lined up as if preparing for a war. The scale was absurdly overwhelming, leaving me almost speechless.

"I''m sorry."

"Huh?"

Lost in these thoughts, my aunt suddenly spoke those words. Why was she apologizing?

"I wanted to make it with a 9th-generation mecha base, but it looks like it won’t be possible."

"Oh."

"A serious defect was found in the core output and material stability. So, unfortunately, we have to proceed with the 8th generation."

So that was the reason.

"What do you mean? I’m grateful even if it’s 8th generation or 1st generation."

“...I see.”

She smiled slightly as she looked at me, a hint of warmth appearing on her usually cold and stern face. I recalled the passionate touch of her body earlier.

Ah. Why am I getting aroused again?

“Hearing you say that makes me want to give you more. I’d really like to manage a way to get you the 9th generation.”

“...Is the issue really that serious?”

Go Min-young frowned, pressing her hand to the bridge of her nose. She usually maintained a calm and icy expression, so it was rare to see her show any sign of frustration, which made it clear that the issue was indeed serious.

“They’re saying they need a room-temperature and atmospheric-pressure superconductor.”

“...Huh?”

“It’s impossible, really. There’s no such thing. It’s uncertain whether it can even be achieved, and who knows how many more years it could take.”

Is this where my RK-99''s moment comes in?

“...So, if a room-temperature and atmospheric-pressure superconductor were developed, it would enable the production of 9th generation models?”

“That would solve the critical issues, yes.”

Then...!

“So, Aunt, if room-temperature and atmospheric-pressure superconductors were developed, how much would you be willing to pay? I assume it’d come with a high price tag, and mass production could be tricky...”

“Price?”

She flashed a cold smile. A chill ran down my spine.

“Nephew, things like that aren’t meant to be bought. They’re meant to be seized and owned.”

“Ah.”

“A superconductor of that value can’t be left in anyone else’s hands, don’t you think? For something that valuable, you use whatever means necessary to take it. Remember that.”
