Became a Failed Experimental Subject-Chapter 32: I Refuse

She said there’d be delicious honey rice cakes, and now she’s toying with me like this?

Gu Seoryong smiled at my cold reaction, slithering across the floor like a snake, smooth and slow.

“If I said it was a nest, you should know what that means, right? When a female monster like me invites a handsome male like you to her nest, you do get the implication?”

“You want offspring.”

“Correct. So? Don’t you want to try it? You and me—our child. I’m sure it’d be a strong one.”

“I refuse.”

I shoved Gu Seoryong off me with one hand as she clung to my arm like a leech.

Her core was pounding, vibrating with excitement, while mine remained perfectly still. When she noticed, her expression twisted just a little.

“Hmph... When you reject me this hard, it just makes me want you more. But still, that hurts a little, you know? You didn’t react at all.”

“I’m not the same type of monster as you. Sending out mating waves doesn’t make me want to fuck.”

“That’s not the point. If a woman gets naked in front of a man and he doesn’t react, of course she’s gonna be upset.”

“If you’re upset, put your clothes back on.”

“Oh my, are you embarrassed?”

“You’re not making sense.”

“Of course I’m not. With a man like you right in front of me... Heh, not that you’d understand a woman’s heart anyway, right?”

She tangled her legs around mine and wrapped her arms around my waist.

I peeled her off, hand by hand, but she kept sticking to me like glue. Irritated, I grabbed her neck.

Tightly.

“If you don’t back off, I’ll break you.”

“Oho... CXI, instead of all this posturing, why not just mate with me and become mine?”

“No. Once I get my necklace back, I’ll leave. Stop wasting my time.”

She adjusted her form again, shifting until we were eye to eye.

“You said you had nowhere to go after the lab, right? I can promise you this—if you stay here, you’ll get delicious meals every day, just like today. You can have anything you want. Women too... I’ll even forgive you specially if you fool around. If you’re bored, you can sleep with whoever you like.”

“So you want me to settle down here.”

“Exactly. With a strong monster like you, I’ve got nothing to worry about. And honestly? I like strong men. A male as powerful as you doesn’t come around twice. So of course I need to lock you down, tight.”

She flicked her split tongue, wrapping it around me.

Her half-liquid body pressed up close, molding itself to mine. Calmly, I tightened my grip on her throat.

“I told you—I don’t like repeating myself.”

“What’ll you do if I don’t let go? Kill me?”

“Yes.”

“Aha! I kinda like that. But tell me... can you really do it? I mean, you’re CXI.”

“...Haa.”

I didn’t exactly want to kill her—she was, after all, a fellow test subject from the same lab. But she was still a monster.

And monsters are meant to die.

I clenched her neck with every intention of snapping it—and watched her throat melt like ice cream.

“Ahaha! You really were going to break it! You’ve changed so much!”

Her head dripped off my wrist like melting sherbet, giggling all the way down.

That wasn’t just body manipulation.

It wasn’t her shapeshifting ability—it was an illusion.

Something was off.

I tried to transform immediately.

“CXI? You won’t be able to monsterize in my room. It’s full of adhesive gas I made myself.”

“Adhesive?”

“A chemical to keep you from shifting out of your human form. Hehe... I didn’t think I’d have to use it like this.”

Now that I focused, I noticed it—an acrid, metallic scent hidden in the mist from the humidifier. The more of it I breathed in, the more solid my body felt—like my joints were locking into place.

It didn’t make any scientific sense.

But one thing was certain—I couldn’t transform.

As that realization set in and my brow furrowed, Gu Seoryong grinned knowingly, as if she could read my mind.

“Aha~ That face is adorable. I bet you’re thinking something like, ‘Why can Gu Seoryong still use her powers? You’re supposed to lose access to abilities in human form, right?’”

“...Correct.”

“You’re cute when you admit things, so I’ll let you in on the secret. This room is also my training chamber! I’ve been working on using monster abilities in human form—drawing them out of the core and channeling them into this body.”

Why the hell would anyone train for that?

And is that really even possible...?

I remembered her fingertips dripping with poison and asked the question out loud.

“You’re mixing monster traits into your human form?”

“Bingo. I call it ‘monsterization.’ Cool, right? And look what I can do...”

Scales spread over her hands and feet. She arched her back and a thick reptilian tail unfurled behind her.

Her once-black hair turned white. Her pupils bled red and split vertically like a snake’s.

That tail lashed out and wrapped around my waist.

Now that her body was in this in-between state, her strength rivaled mine. She forced my arm down—something she hadn’t been able to do before.

Amazing. So it is possible to fuse human and monster forms.

Even like this, still technically humanoid, Gu Seoryong was radiating close to Calamity-level energy.

I wouldn’t say it was something I’d want to learn myself—didn’t seem all that efficient—but I had to admit, it was impressive.

“Doesn’t seem all that useful. Why train like this?”

“Because a woman always wants to look her best. My monster form doesn’t have your charm—it’s not cute, and definitely not sexy, Blaccky.”

At the name “Blaccky,” my eyes widened.

Gu Seoryong, sensing my reaction with her sharpened senses, smirked.

“Knew it. You are Blaccky, huh?”

“How did you know?”

“I was just fishing, but it made sense, right? CXI is Calamity-class. Blaccky is Calamity-class. And a monster that protects humans? Not exactly common.”

“That’s all it took? Impressive.”

“Total guess—now it’s confirmed, though.”

To realize I was Blaccky from just that... she must be smarter than she looks.

Her tail stretched further and coiled tightly around me like a rope, locking me in place.

“Hehe... Since you’re Blaccky, I’m curious—why are you helping humans? You’re a monster.”

“Is a monster not allowed to help humans?”

“Well, not not allowed, but... it’s weird, right? I mean, we’re wired to see humans as food. You can feel it, can’t you?”

She wasn’t wrong.

The smell of blood made my mouth water.

Even the scent of dying thoughts made my core pulse.

Monsters are predators. Humans are prey.

To hunt for them—goes against what I am.

But.

“Instincts can be ignored.”

“Aha! Ahahahaha! That’s so you, CXI! Of course. If you were the kind of monster who followed instincts, you’d have eaten every other test subject back in the lab and gone full monster by now. But no—you’re the kind that does only what he wants. And never what he doesn’t.”

“I don’t want to mate with you.”

“Well, I’m the same. A monster who always does what she wants. Even if you won’t be mine, even if you won’t stay in my nest, if I get your seed—I know I’ll have a strong baby.”

Her pheromones, thicker than the mist in the air, swirled around me. My voice remained flat.

She flinched.

Poison glistened at her nails.

“...But you know, you’re way too calm right now. Isn’t that weird? I’ve got you completely pinned, and you’re not even tense.”

“Why should I be? You’re too weak.”

Sure, the power radiating from Gu Seoryong hovered somewhere between Calamity-class and Despair-class. But even at that level, the most she could manage was to scratch me a little.

She couldn’t kill me. No matter what she tried.

Like a cat effortlessly overpowering a snake—no matter how wildly she thrashed in front of me, it only came off as... amusing.

Even if we were both monsters, the difference in our level was night and day.

“Hmph... annoying, but hot. Yeah, a male worth taking seed from should be at least this strong.”

Gu Seoryong, eyes glinting with intent, dug her poison-tipped claws into my shoulder.

It wasn’t an ability—just the raw venom generated by her monster body.

She injected a heavy dose of paralytic poison meant to freeze the body completely. As my limbs stiffened, she pushed me down onto the bed, then slowly licked the blood and venom off her fingertips.

“With this much in you, even you won’t be able to move for a full day. Well? How’s it feel? Been a while, hasn’t it?”

“Is this... a tranquilizer?”

Just like that, my body turned thick and sluggish, like my limbs had been dipped in industrial grease. The sensation reminded me of the tranquilizers I used to be hit with back in the lab. I frowned.

Before I could process the sensation further, her fingers snapped.

Snap. Snap... Snap.

The sound echoed unnaturally, and ripples spread across my vision—circular, like shockwaves on water.

Flashes of white and black alternated in my line of sight, scrambling my sense of direction.

“Whaaat do you think~? Not baad, right? It's a technique made just for monsters!”

“...I can hear it... what did you do?”

My vision kept shaking. I blinked, trying to stabilize it—like regaining balance on a rocking boat. For a moment, I could see clearly, hear clearly... then the waves returned.

“That’s a secret, CXI. If I tell you, you’ll just adapt. And we can’t have that yet, so just stay put, alright?”

“...Tch.”

Her fingers clenched into a fist and opened again. Then she jammed her claws into my neck.

Gulp, gulp. A disgusting, wet sound followed as more venom entered my bloodstream.

My head buzzed. A wave of euphoria spread. Her monster core throbbed with low, club-like bass that thumped through my body like it owned the rhythm of my nerves.

The way the sound synced with my neurons twitching reminded me of those humans grinding against each other in the clubs.

Staring at her now-warping form, I muttered:

“The drugs you sell in the club... are they made from your poison?”

“Bingo. What do you think? I said I was listening. But I wonder how long you can keep up this act~? Ohoho, just wait, you’ll be moaning for mercy soon enough.”

“...Hmm.”

I closed my eyes, focusing ~Nоvеl𝕚ght~ on the core buried deep inside me—moving slower than cement.

Toxicity, paralysis, illusion, that adhesive mist... All of it—I could digest.

If I devoured every one of these effects, I’d regain full control of my body.

It would just... take time.

“You’re stronger than I expected.”

“Oho~ does that mean I passed? Will you give me your seed now?”

“Not quite.”

Gu Seoryong, fully aware of that fact herself, pulled back her tail and scales, smugly perched on top of me with a satisfied smile.

“Ahaha! Doesn’t matter. You’ve already got enough of my venom in you to be totally addicted. Even if I have to squeeze it out of you...”

Then it happened.

Far beyond the glass wall of the window—a comet streaked across the sky.

I narrowed my eyes at the all-too-familiar shape, and Gu Seoryong’s grin dropped. She turned to look outside.

The comet descended... and slowly shifted into the shape of a person.

A figure stood just beyond the glass, hovering.

“The fuck is this?”

[Gu Seoryong. Boss of Guryong Fortress. Leader of a villain syndicate.]

Starlight’s voice, flat and commanding, rang out as she hovered in place. Her expression twisted when she spotted me and Gu Seoryong through the glass.

With a single finger, she drew a huge circle in the air.

The window melted away without a sound. It slid down, piece by piece.

From the club below, voices began rising—people murmuring, noticing the sudden entrance of a hero. The music still thumped, but tension snapped the air tight.

Starlight stepped into the room.

“Bribery of government officials. Murder, robbery, theft, prostitution... Do I even need to keep going?”

Her expression was colder than I’d seen in a long time.

She raised her fist, and a brilliant white flame bloomed.

She blew on it—fwoosh—extinguishing it casually before pointing that hand straight at Gu Seoryong.

“You’re under emergency arrest by my authority. If you don’t want to die, I suggest you come quietly.”
