The Dark Night That Burns Beneath the Skin
“Ugh…”
Ever since the rough aftermath at Do-yeon’s hidden spot, my lower body had burned hot.
Something inside me pounded like it wanted to burst out.
Hot… and yet strangely warm.
*Is this… my inner energy?*
It made perfect sense that I could feel inner energy pulsing from my cock. And yet I still didn’t understand it.
In the original novel *Muryim Iltong*, the dantian had strict limits—cock and pussy. A man’s and a woman’s genitals were simply the dantian.
That was why the men here were so weak. Even their balls couldn’t be that big.
In wuxia stories, you never drew lines you couldn’t hold. But the world itself made becoming a male martial artist almost impossible.
*So I thought I’d be different…*
The energy swirling in my groin. A world where cock and pussy were the dantian.
Combining the two, I could guess what I was feeling: inner energy.
*Should I try qigong?*
I didn’t know how. I didn’t even know what to circulate. Just tell me to spin the energy in my lower belly? Forget it. Spin it through my cock? Impossible.
But the discomfort kept getting worse.
*Fuck… If this keeps up, I’m going to get cock-possessed, right?*
Girls got pussy-possessed? Ridiculous.
While my brain was spinning filthy nonsense, a voice called from outside the cage.
“Baek Mujin. You okay?”
“Ah, Ah-jin noona.”
“Your face looks pale. I told Do-yeon to stop messing with you…”
“Just… help me… my cock feels like it’s on fire…”
Her expression changed instantly.
“Did you just learn any martial arts?”
“I… don’t know… ugh, noona…”
“Damn it, get out first.”
Ah-jin unlocked the slave cage where the others were sleeping, pulled me out, and dragged me straight into the forest.
She yanked my pants down without a word.
“…Your inner energy is raging. After sex, male martial artists must cultivate qigong. You don’t know that?”
“I don’t know…!!”
The protagonist never had sex, so how was I supposed to know? At the very end he just fucked and passed out.
“This won’t do. Your cock will break if we don’t do something. Can I help?”
*Fuck.* If my cock broke, the entire harem life was gone.
No hesitation. “Yes, yes! Please help me!!”
“Hmph. Understood.”
She’d kissed me before, right? Before I could think, Ah-jin’s lips closed around my cock.
“Uuuuh…”
“Mmmph… gluck… glurk…”
“Haa…”
The instant my cock slid into her throat, the burning pain vanished.
The raging energy steadied. At first I thought *inner energy really is like this?* Then a wave of heat spread through my entire body.
“Ugh… ugh… yeah… good… gluck…”
I forgot how to speak. I just focused on the energy flooding my cock.
Dense, heavy inner energy packed into my balls.
It flowed smoothly around my shaft, following the rhythm of Ah-jin’s mouth. I struggled to memorize every sensation while thrusting my hips.
*This… this is inner energy…*
“Aum… gluck…”
A mysterious, intoxicating feeling swept over my whole body. My already-taut muscles filled with fresh vitality.
The faster the energy circulated, the faster Ah-jin’s head bobbed back and forth.
“Noona, I’m cumming…!”
The moment the inner energy completed its loop, white-hot pleasure exploded. Thick ropes of semen erupted.
“Uuuuh…!!”
*Splash!* *Pfffrrt!* Ah-jin hugged my thighs and took every drop, swallowing like she meant to keep them all.
A second later she pulled my still-twitching cock from her mouth and milked the last drops straight into her waiting throat.
Even after finishing, she looked healthy and strong. Power radiated from her entire body.
“Uum… haaa…”
Ah-jin kept swallowing until her mouth was full, then cupped both hands and spat the leftover semen into them.
Thick, glossy, pearl-white jelly-like cum dripped from her palms.
When she finally spoke, her voice was hoarse.
“…This is a pure cultivation technique. I’ve never seen such thick, snow-white semen before.”
“…Does the technique change the semen?”
“You really don’t know anything. The properties of male semen depend on the cultivation method.”
So the plum-scented fluid my hyung had searched so desperately for… was this.
“Especially the Emei Sect’s semen is said to be pure white. He must have been a great monk.”
A little dizzy, but I accepted it. If that was true, then different techniques would change the tightness of a woman’s pussy too.
I wanted to ask, but I couldn’t.
Standing there awkwardly, Ah-jin kindly pulled my pants back up and patted my head.
“You must be exhausted after two loads today. Even as a slave, you can’t be treated like this. I’ll punish Do-yeon properly later. Go rest in the corner.”
My body still felt like I could go another few rounds, but for today this was enough.
Actually, something had been bothering me since the moment I woke up.
*Black Heaven Ink Earth Divine Art.*
Just like the memory by the river, the name of a martial art burned into my mind.
The inner energy inside this body was clearly tied to that technique.
I returned to the camp with Ah-jin and lay down in the farthest corner.
Slaves were supposed to sleep in the cage, but after two loads she said I could sleep comfortably.
“Does cumming make you really tired?”
“Ah?”
Ah-jin tilted her head and looked at my bulge.
“…You’re a little different. Most men need three days of rest after one load to replenish. That’s why they schedule good days for relations.”
*Understood.* In this era, marriages probably happened around sixteen. Still, her words hit hard.
And a question rose: if you needed to store semen for your wife before marriage, what about before that?
“Sir, then you don’t even touch women before marriage?”
“W-what?! What filthy thing are you saying?! I’m not like that!!”
“Haa…”
I sighed and shook my head. The sight of a middle-aged man blushing and stuttering was almost impossible to watch with dry eyes.
*Let me try qigong again.*
I lightly touched the heavy balls full of energy. Inner energy swirled obediently in circles.
At the same time, vitality flooded my entire body. I could probably smash this wooden cage if I wanted to.
*Escape?*
I reached to touch the bars, then stopped.
*Too risky.*
Even as a slave, my treatment was decent. My own brother’s slavery days had been worse.
Meals on time, noonday nap, noonas tempting me while half-naked, all of it.
And the most important part: there was nothing I could do outside these walls.
*Better to head to the nearest martial sect and watch quietly.*
As I’d said earlier, the martial sect was the protagonist’s first destination—the place where he trained and grew strong.
There were hidden opportunities, important people. No sudden super-strong enemies.
*…Yeah, that sounds right.*
The protagonist always won with pure martial arts. So I wouldn’t face an enemy I couldn’t beat.
“Whew…”
With that simple plan, qigong finished. It was already noon.
We stopped near the mountain trail. I killed my first meal and approached Ah-jin again.
My cock was still hot from qigong and I couldn’t stand it.
“Noona.”
“…Hm? What?”
Ah-jin was my escort, but technically we were purchased laborers of the martial sect.
We weren’t slaves in the strict sense.
I pressed my swollen bulge against her and whispered.
“My cock got hot again… please help.”
“…Only this time.”
“Whew… You sure you’re okay? Not dizzy or anything?”
“Yes, noona. Please suck as much as you want.”
Ah-jin wanted to test it. Yesterday she’d been flustered and could only speak stiffly.
In truth, she still wanted to suck the strong cock that hadn’t even softened after the first load.
The pungent, brain-melting scent. The thick, sticky semen that poured into her mouth until it overflowed.
Its size—I’d noticed it before, but seeing it up close made my jaw ache.
But I had to keep it clean for the sect, so I endured.
*Something in my mind had changed.*
The thick, heavy shaft begged me to suck it.
I opened my mouth and took in the thick head. My chest started pounding with excitement.
My lower body was already wet.
“Gluck… glurk… mmm…”
Unlike any other man, his large, thick hand rested on my head.
The comfort and stability I’d never felt from any man in my life soaked into me. I wanted to submit to this man. To this cock.
“Gluck… gluck… haa…”
Even if I took as much as possible, my cock was too big to fit halfway.
Thick columns that one hand couldn’t grip, lengths that two hands couldn’t cover.
His deep eyes looked down at me. My whole body shivered.
*Men like this…*
I could feel his thick cock hardening. The sign that he was close to cumming.
Ah-jin’s fingers quickly stroked the shaft. The spit-slicked head rubbed against her rough tongue and twitched.
“Guh… noona…!”
“Uum…!!”
Hot semen blasted into my throat. I coughed but swallowed every drop.
Slowly, the hot, milky fluid filled my mouth.
“Gluck… uum…”
I looked up at him and cleaned every last drop inside.
His hand stroked his own cheek in satisfaction.
“Puhahaaa…”
Steam rose from his open mouth like he’d eaten a hot dumpling.
The dense, pungent semen smell made my head spin. When I stuck out my tongue to show I’d finished, Mujin’s lips curved into a smile.
“Thank you, noona. Thanks to you, I feel better.”
“…Mm.”
He tucked his still-hard cock back into his clothes and returned to the camp.
It was good that he’d come again. The thought looped in my head. I wanted to taste that thick feeling again and again.
Fortunately, that evening he returned. He pressed his cock against me once more.
---
The mountain trail creaked under our feet. The other slaves walked behind me, still exhausted from the long ascent. Ah-jin walked at my side, her hand occasionally brushing mine—once, twice—like she was checking I was still okay.
My cock had finally softened after the second load, but the memory of her mouth made it twitch every time I remembered how thick and heavy it had felt sliding between my lips.
*This world really is full of surprises.*
I glanced at the sky. The sun was already dipping behind the peaks. The air smelled of pine and distant rain.
We reached the small outpost at the edge of the forest. A few tents were set up, and a few disciples nodded at us as we passed.
Ah-jin stopped me at the edge of the clearing.
“Wait here a moment. I’ll bring back some clean clothes for you.”
I nodded and leaned against a tree, watching the other slaves collapse onto the ground. One of them muttered something about how this was better than the cages.
My eyes lingered on the empty space where Do-yeon had been. She was still being punished, I knew. Ah-jin’s warning still echoed in my ears.
*Don’t let her near me again.*
The thought should have made me feel guilty. Instead, a strange warmth spread through my chest.
*She’s not even mine yet, and I’m already protective?*
I laughed quietly to myself. The laugh turned into a wince when a sharp throb ran through my groin.
*Again?*
I pressed my thighs together and tried to focus on the trees around me. The leaves were starting to turn gold and red. Autumn was coming.
A soft footstep behind me.
I turned. Ah-jin was there, holding a bundle of simple clothes—loose pants, a thin shirt, and a clean pair of underclothes.
“These are the clothes the disciples wear. They’ll fit you better than what you’re wearing now.”
She handed them over. Our fingers brushed. Her cheeks were faintly pink.
“Thank you, noona.”
“Don’t mention it.” She looked away, then added softly, “…and Mujin. If you need anything—food, water, anything—tell me. I’ll make sure you get it.”
I took the clothes and nodded. For a moment I was at a loss for words.
*She’s treating me like a real person.*
The thought felt almost embarrassing.
Ah-jin turned to leave, then paused.
“Oh, one more thing. The sect leader is coming to inspect the new arrivals tomorrow morning. I’ll be there as well. You… should be careful around him.”
I blinked. “Why?”
She hesitated, then said, “He’s strict. And… he has his own rules. If he ever asks you to do anything, just do it. Don’t cause trouble.”
Her voice was gentle, but her eyes were serious.
I didn’t fully understand what she was warning about, but I nodded anyway.
“Thank you. I’ll be careful.”
Ah-jin gave a small smile—the first one I’d seen all day—and walked back toward the tents.
I watched her go, then quickly changed into the spare clothes. The fabric was soft against my skin, but the size was perfect. I felt strangely clean for the first time in days.
When I stepped out, the other slaves had already eaten and were resting. I found a quiet spot behind a large rock and sat down.
The sun was almost gone. Stars were starting to appear above the treetops.
I closed my eyes and let my mind drift back to the forest.
Ah-jin’s mouth. The way she’d swallowed everything. The thick, heavy weight of her hand on my head.
My cock twitched again. I pressed my palm against it through the loose pants and exhaled slowly.
*If I keep thinking about it, I really will get hard again.*
I forced my thoughts elsewhere.
The sect leader. The inspection tomorrow.
I didn’t know what kind of man he was. Ah-jin’s warning didn’t sound like casual talk. Whatever he was like, I needed to be ready.
A small shadow moved at the edge of my vision.
A figure stepped out from behind the rocks—tall, hooded, carrying a lantern.
The light from the lantern fell on his face.
Mujin’s eyes widened.
“Jang Dusik…”
The name flashed through my mind like a warning bell.
The mortal enemy. The man who had once sworn to kill me.
He stopped a few steps away and stared at me.
His voice was low and cold.
“So the new slave is Baek Mujin. I heard you caused quite a stir today.”
I stood slowly, heart hammering.
The night had only just begun.
