Mansang Realm
When I opened my eyes, a thick fog blanketed the forest, and through the trees stood a shrine so weathered it looked ready to collapse at any moment.
So this is the Fairy Shrine.
The crimson mist of Hongyeon Valley clung tightly around the ruined structure. Hiding out here for a while seemed like a solid plan.
“Nngh…”
A pained moan drifted from behind me. I turned. Seo Ran lay completely still, as if her entire body had gone numb. Beads of cold sweat dotted her pale face.
Spirit Meridian Powder mixed with Dazing Fragrance, huh? Looks like it worked perfectly.
Mansang Realm was no orthodox immortal realm. Even cultivators could be affected by poison. In particular, Spirit Meridian Powder—refined from the bone dust of those who died failing to ascend—could, when paired with Dazing Fragrance, temporarily cripple even a true cultivator. There weren’t many toxins that could do that.
Either way… this is the absolute best moment to fuck her.
But if I took her right here and now, the second the poison wore off she would kill me without hesitation.
I’ve got Sperm Addiction, sure… but I still don’t know how strong the effect really is.
I’d fed small amounts to Dan Ha and So Ryeong before, but aside from mild addiction symptoms there hadn’t been any dramatic change. Whether it would properly take hold on a Gold Core expert was still unknown.
For now I needed to get her inside.
“Sect Leader, are you all right?”
“Ugh…”
“We’ll stay here until you recover.”
“Nngh.”
“Then, if you’ll excuse me for a moment.”
I lifted Seo Ran’s limp body from the ground and carried her in my arms.
Her skin is ridiculously soft.
Especially the full, heavy breasts spilling out through the torn fabric of her robe, and the rosy nipples standing stiff at their tips—my eyes locked onto them on pure instinct.
I swallowed hard and forced my gaze away. If I kept staring I was going to jump her for real.
Keeping my eyes fixed straight ahead, I carried her deeper into the shrine. Thankfully the interior was far larger than the crumbling exterior suggested. Dust lay thick everywhere, but the ceiling was intact and none of the walls had collapsed.
I kicked a relatively clean patch of floor clear and carefully laid her down.
Next order of business… finding that manual.
Before she recovered I needed to secure the single most powerful weapon that would let me claim her body with something resembling legitimacy.
“Lady Seo Ran, rest here a moment. I’ll be right back.”
“Nngh…”
I made a half-assed excuse and began searching the shrine. After a long while I spotted a narrow passage hidden behind the stone statue of a fairy.
There it is.
I carefully pushed the statue aside and squeezed my body into the passage. It was barely wide enough for a grown man. After only a few steps a small stone chamber opened up.
The walls were covered in carved patterns.
I stepped closer and wiped away the dust with my hand. Intricate reliefs of men and women entwined in every possible position emerged beneath my fingers.
I turned toward the altar. A small stone box sat on top of it.
I lifted the lid slowly.
Creeeak—
Inside lay a single ancient book. Five characters were carved into the cover.
Ancient Dual Cultivation Manual
Absorbs a partner’s Yin energy during intercourse to accelerate cultivation.
Found it.
The moment I pulled the book free and opened it, densely written characters filled my vision. Strangely, simply skimming the pages caused the contents to etch themselves into my mind as if they had always been there.
This… isn’t the lewd art I was expecting.
Honestly, when I heard “dual cultivation” I had been hoping for something flashy—techniques that clouded the partner’s mind or cranked their sensitivity to the breaking point. What I got was nothing like that.
The essence of the Yin-Yang Dual Cultivation Scripture was achieving perfect harmony of Yin and Yang during intercourse. It was a pure cultivation method, laser-focused on training.
Well, it still makes me stronger. Good enough.
A little disappointing compared to my fantasies, but it would still accomplish the goal. And I already had the Sensation Amplification reward from the quest; any shortfall could be patched with that.
Let’s study the contents properly first.
I spent a good while absorbing every detail of the scripture.
The core principle was simple. The partner’s Yin energy flowed into my dantian while my Yang energy poured into her. At the peak of union the two energies hungrily coiled around each other, reaching an extreme state of harmony.
And the most important point was this:
The higher the partner’s realm, the greater the gains.
And the most effective partner of all…
Conveniently, there’s a living elixir at Gold Core stage waiting right outside.
I left the stone chamber and returned to where Seo Ran lay. She still couldn’t move properly, breathing in short, shallow gasps.
Decision made. I’m fucking her.
I had entered this world to grow stronger. Leaving the finest spiritual medicine in existence lying unused right in front of me would be pure stupidity.
If I keep pumping her full of cum, Sperm Addiction will take care of the rest.
I decided to be optimistic. The Infinite Library had given me the skill; there was no way it would be weak.
First I needed to fully internalize the scripture before I moved.
I sat a short distance away, closed my eyes, and reviewed every line of the Yin-Yang Dual Cultivation Scripture in my mind. Because the contents had engraved themselves the moment I skimmed them, recalling everything was effortless.
When I opened my eyes again I looked at Seo Ran.
She forced her eyelids open with great effort. Her purple irises locked onto me.
“…You… over there…”
“Sect Leader, you can speak?”
“…Yes.”
I approached her slowly and, just to be certain, checked her condition.
“How do you feel? Can you circulate your qi at all?”
“No… I can’t move a single strand… They said it was Spirit Meridian Powder… I’ll be unable to use qi for at least two weeks.”
“Two weeks, huh.”
Perfect.
That meant for two full weeks she would be completely helpless.
I kept my expression carefully worried as I continued.
“At least it’s not a poison that threatens your life. That’s a relief.”
“Just because it won’t kill me doesn’t make the situation good.”
“True enough.”
I sat down beside her and kept talking.
“You’ll have to stay here for those two weeks. We’re deep inside Hongyeon Valley, so the pursuers won’t dare enter because of the demonic beasts.”
“More importantly… what’s your name?”
“Lee Seo-jun.”
“Lee Seo-jun… Never heard of you…”
“I only entered the Red Blood Sect recently. That’s probably why.”
I watched her face carefully while I spoke.
“Sect Leader, do you think Wang O and Wang Tae-ho will keep hunting us?”
“They will. What they wanted was the Blood Lord Token…”
“Then even this place isn’t completely safe.”
“No. Those two can’t enter Hongyeon Valley.”
“Why are you so certain?”
“Anyone who truly understands Hongyeon Valley knows exactly what rules this place.”
She let out a heavy sigh and continued.
“We shouldn’t be worrying about Wang O and Wang Tae-ho. We should be wary of the ruler of Hongyeon Valley.”
Her words made it clear there was still something about the valley I didn’t know.
“By the way, Lady Seo Ran… is that thing around your neck the Blood Lord Token?”
“Why do you ask?”
Her eyes narrowed.
“Just curious.”
She said nothing and simply glared at me. It was obvious she thought I was after the token.
I’ve confirmed everything I needed… Time to start.
Two weeks of intensive dual cultivation would be tight. Hell, the two weeks she claimed might even be a lie. If I wanted to turn her into a sex slave who thought of nothing but my cock within a week, I had to begin immediately.
“Sect Leader, one last question.”
“I’m tired of your questions. Stop.”
“I still can’t help being curious. Are you a virgin?”
“…What exactly… do you mean by that?”
I smiled and pulled the torn edges of her robe farther apart. Her full breasts spilled completely free, the rosy nipples standing proud and impossible to ignore.
“Because if you are, you’ll taste even better when I fuck you.”
“Y-You… You bastard… waiting until I was poisoned to…”
I wrapped my entire palm around one heavy breast. Soft warmth flooded my hand.
“Just answer me. Virgin or not.”
“Shut your mouth! How dare a mere outer disciple even think of defiling the Sect Leader!”
Seo Ran’s voice cracked, trembling with pure rage.
I pinched one nipple between thumb and forefinger and gave it a sharp twist. At the same time I activated Sensation Amplification and cranked her sensitivity tenfold.
“Ahhhk—!”
A long, heated moan tore from between her red lips.
I twisted again.
“A-Ahhng…! You… you fucking dog…!”
I gave the other nipple the same treatment.
“Nnghiiit…♡”
“Wow. The lofty Sect Leader of the Red Blood Sect is making the filthiest sounds imaginable.”
“Haa… haah… You… you dare…!”
I twisted both nipples harder and grinned.
“Feels good, doesn’t it, Sect Leader? Of course it does. Then I’ll make you cry even prettier.”
One hand kept kneading her breasts while the other slowly hiked up her skirt.
Her pale thighs came into view, and between them her pussy was already glistening faintly with wetness.
Her eyes burned with pure murder as she glared up at me and shouted.
“You… do you really think you’ll walk away from this alive?!”
I dragged a finger slowly from the bottom of her slit all the way up, then began rubbing circles over her clit.
“Yeah, I do. And also…”
I peeled back the hood of her clit, fully exposing the hypersensitive pearl. Instant terror flooded her purple eyes.
“You still don’t understand the situation, do you?”
“S-Stop…!”
I smiled and pressed my thumb gently down on her clit. Simultaneously I pushed Sensation Amplification to twenty times normal sensitivity.
“Nngiiiit♡”

Pssshhhhhh!
A powerful jet of pussy juice exploded from her.
“Tsk tsk. A woman of your age shouldn’t be squirting like a little slut.”
“Hiiik…! S-Stop…!”
I kept rubbing slow circles over her clit with my thumb, then flicked it hard with a sharp snap of my finger.
Smack!
“Hngiiiik—!!”
Another scorching stream of fluid sprayed out. Her eyes rolled back slightly and her tongue lolled from her open mouth.
“That face is fucking hot.”
A beautiful woman’s ahegao was always the correct answer.
