Martial Emperor of Blue Star, Turned into a Blood Slave Girl by a Vampire Princess

Catherine’s fingertips trailed slowly up the inside of her thigh, every inch of movement searing into her nerves like a flame.

“I…” Her voice was barely a whisper, like a mosquito's buzz squeezed through clenched teeth, “I am Lady Catherine’s…”
“Mm?” Catherine suddenly pressed harder, her nails sinking into the tender flesh at the base of her thigh. “Can’t hear you.”
The sudden jolt of pain made Degrienne flinch, her eyes instantly brimming with tears. “I… I’m your private pet!”

The words came out with all the strength she could muster, the last syllables choked by a sob.
Catherine tilted her head, red eyes glinting with cruel delight. “Not enough. Say it properly—”
She yanked open Degrienne’s lace collar. “What are you?”

“S-slave…”
Degrienne’s entire body flushed with shame, tears threatening to spill from her eyes.
“Forever belonging only to Lady Catherine… P-please, let me serve my Mistress…”

“Now that’s more like it.”
A smile of satisfaction curled on Catherine’s lips. With a flick of her finger, thorny vines materialized from the air, shredding Degrienne’s maid uniform into tatters in seconds.
“You broke your promise!”

Degrienne cried out, scrambling in vain to cover her exposed body. “You said you wouldn’t—!”
“Relax. I know my limits.”
Catherine bit down on her earlobe, her hand pressing against her heaving chest. “Now… it’s time to collect tribute from my pet.”

Outside the chamber, Isabella stood in silence.
Soft, stifled whimpers leaked from behind the royal bedchamber door. Without a word, Isabella smoothed the lace at her cuffs and melted into the darkness of the corridor.
Over an hour of “affection” passed before Catherine, finally sated, brought her torment to a pause.

Degrienne stumbled out of the bedchamber, wrapped in scraps of her uniform.
Her entire body was soaked. Her legs were so weak she could barely move them.
She practically crashed through the dormitory door and rushed into the bathroom.
Steam wrapped around her as she stood beneath the scalding water.

She scrubbed at her skin with force, trying to erase the bite marks. Her flesh turned red from the friction.
But no matter how hard she tried, she couldn’t wash away the rose scent clinging to her—Catherine’s scent.
“Damn it…”

She glared at her own reflection. Her flushed skin, her long silver hair plastered to her back… there wasn’t a trace of the former Martial Emperor left.
What made her stomach churn most of all was that when Catherine's tongue had slid across her skin… she had actually…
The water suddenly turned ice-cold, and Degrienne shivered.

Catherine had, in the end, kept her promise—hadn’t gone all the way—but that somehow only unsettled her more.
That lunatic was clearly enjoying this sadistic game of cat and mouse.
She wrapped a towel around herself and sat on the edge of the bed, unconsciously measuring her height with her hand.

This body couldn’t be more than fourteen years old. Even smaller than her college-aged little sister.
If… if she really did make it back to Blue Star, what would her sister say upon seeing her like this?
That brat who used to pull faces behind her back would probably have to stand on tiptoe just to pat her head now.

“Pff—‘Big Brother’?”
She could almost hear her sister trying not to laugh. “Should I call you sis now? Or little sister?”
Just picturing her smug little face poking her cheeks made Degrienne grind her teeth.

Lying back and staring at the ceiling, she sank into even deeper conflict.
If she stayed, Catherine would eventually devour her whole. But if she escaped—what then?
She let out a bitter smile. Maybe this was the price of being a hero.

Lost in thought, she suddenly felt a chill crawl up her spine.
Isabella had appeared again—without a sound—holding a clean maid uniform and ribbons. Her voice was calm.
“Lady Catherine instructed me to help bathe you.”

“You again!”
Just seeing this girl who’d dragged her to Catherine’s chamber made Degrienne’s teeth ache with rage.
“You vampires are all monsters! Get out, I’ve already washed!”

Isabella paused for a moment.
She lowered her head slightly, her long lashes casting a shadow. Her lips moved faintly. “…Monsters, huh?”
The words were so soft they barely registered.

But in the next second, she was back to her expressionless self. “I’m sorry. But Lady Catherine’s orders are absolute.”
Before Degrienne could resist, Isabella had already unfolded the maid uniform with practiced ease.
Degrienne tried to push her away, but was easily pressed against the mirror.

Cold fingers slid through her silver hair, and a comb gently scraped across her scalp.
Every strand was carefully brushed, then tied into a precise butterfly ribbon.
“Let me go!”

Degrienne squirmed, but the reflection in the mirror only became more refined under Isabella’s hands—
Her pale cheeks were flushed with anger, her silver hair fell like satin, even her pouting lips looked… tender.
When the final ribbon was tied, Isabella took a half-step back and appraised her work with silent satisfaction.

She gave a shallow curtsy, her figure fading into the shadows. “Please continue with your duties shortly—”
She paused, then added softly, “You… are very beautiful.”
Degrienne hurled the comb at the empty corner of the room. “Who asked for beauty like this?!”

The angry little girl in the mirror puffed out her cheeks—somehow, even her fury looked adorably helpless—
The realization shattered her further.
She sulked in silence for a while, then locked the door, ensuring no one was around. She climbed onto the bed and sat cross-legged, summoning the system interface.

【Host】: Degrienne Lilith
【Desire Points】: 15 (earned during PUA event)
【Available Infusion Option】:
1. Lightning Induction Body Tempering Technique (Minor Completion)
“System, begin simulation,” Degrienne murmured.
The system’s voice echoed coldly:

【Year 1】
You sit in meditation. Blood-red lightning surges through your meridians.
Each arc scrapes your bones like a blade. Cold sweat soaks your back.
But this time, you clench your jaw and bear it in silence.
【Year 5】
The lightning easily takes physical form.
While training behind the castle, a whip of thunder lashes out, splitting a tree three men wide in half.
The charred stump smokes.
Maid patrols rush over—Catherine spanks your ass until it's swollen.
【Year 10】
The lightning begins to transform your physique.
When you punch, the air cracks. At top speed, you leave afterimages.
But in the mirror, your red eyes shine brighter. Your fangs can no longer retract through sheer willpower.

【Year 15】
You finally touch the threshold of Major Completion.
Now your lightning strikes are thick as bowls, melting holes in solid steel.
During one loss of control, a thunderstorm tears off the kitchen roof—
Veronica sentences you to scrub floors for three months.
Simulation complete. Lightning Induction Body Tempering Technique — Major Completion!
Boom!

Degrienne’s eyes flew open. She drove her fist into the stone wall.
The impact left a deep crater, cracks spiderwebbing out from it. Thin arcs of electricity still danced in the crevices.
She clenched her fist, feeling the surging strength within—she could easily lift a thousand pounds.

If she faced that werewolf from the arena again, she was confident she could snap its spine in under ten moves.
“Still not enough…” she muttered, staring at the lightning flickering on her fingertips.
Compared to a monster like Catherine, this progress was nothing.

But at least—it was a step closer to escaping this cage.
As the lightning dimmed, her flushed cheeks reflected in the mirror.
Degrienne licked her dry lips on instinct—only to feel something sharp graze her tongue.

“Tch—!”
She leaned close to the mirror, baring her teeth.
Sure enough, the right fang was poking out, glinting coldly.

She pressed a fingertip to it—pain shot through her finger, leaving a deep indent.
“How the hell am I supposed to blend into human society like this…”
She grumbled, but couldn’t deny it: paired with this doll-like face, there was a dangerous kind of charm.

What worried her more was the pace of her cultivation.
In just a few days, the Lightning Induction Body Tempering Technique had reached Major Completion, and her realm had advanced to Body Tempering Tier Six.
Such progress would have caused an uproar back on Blue Star.

Would that old demon Catherine notice?
Degrienne irritably yanked at her lace hair ribbon, her mind flashing back to tonight’s bedchamber service—
As humiliating as it was, the Desire Points she earned were absurdly high.

“Damn it…”
Blushing furiously, she tied on her apron. To grow stronger through this kind of… training—it was—
Just then, the hallway bell rang, snapping her back to reality.

If she didn’t get to work, that maniac with the silver ruler—Veronica—was going to have her bent over a knee in no time.
Degrienne smoothed her aura, took ❀ Nоvеlігht ❀ (Don’t copy, read here) a deep breath, and stepped out of the maid dormitory.
