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

Degrienne’s hand hovered in midair, fingertips trembling.

Isabella’s cheek was already flushed red, yet she remained calm, gazing at her as if silently waiting for the next slap.
“Lunatic…” Degrienne’s voice shook. “You’re really… a damn lunatic…”
But Isabella gently cupped her hand, pressing it to the warmth of her cheek.

“Please don’t be angry at Lady Catherine. If hitting me helps you feel better…”
A plea flickered in those dark crimson eyes. “Then punish me all you like.”
That sentence shattered what little restraint Degrienne had left.

“Fine! If you’re that eager for a beating—”
She lunged forward and tackled Isabella, both hands clamping down hard around her throat. “Then I’ll beat you to death!”
Lightning exploded in her palms, sparks racing from her fingers into Isabella’s throat.

Lightning Induction Body Tempering Technique surged at full force—Degrienne poured every last shred of her cultivation into it.
Isabella’s face began to flush red, her lashes trembling with pain. A faint whimper escaped her throat.
Her fingers clutched the bedsheets instinctively—then forced themselves to let go, letting Degrienne do as she pleased.

Half an hour later, Degrienne collapsed, spent and shaking.
Her face rested against Isabella’s soft chest, her silver hair drenched in sweat, tangled between their overlapping bodies.
“Ugh…”

A sob tore from Degrienne’s throat. “Why… why do you have to play with me like this…”
Her fists thumped weakly against Isabella’s shoulder. “I’m only at Body Tempering Tier Six… how could I possibly hurt someone at Grandmaster Tier Eight…”
Tears soaked through Isabella’s undergarments. “And you even pretended to be in pain… do you think I’m stupid…”

Isabella blinked in surprise—then gently stroked her back.
Her voice was hoarse from being throttled. “I thought… it might make you feel better.”
Her fingertips brushed the collar around Degrienne’s neck. A flicker of emotion stirred in her dark eyes, but it faded into a softer caress.
“Do you want to choke me again? This time… I’ll actually let myself get hurt.”

Degrienne raised her tear-blurred face—and saw that Isabella had dispelled her protective «N.o.v.e.l.i.g.h.t» aura. Faint bruises had begun to form across her pale neck.
The realization only made Degrienne cry harder.
Isabella quietly wrapped her in an embrace, gently stroking her back like she was calming a frightened animal.

Only after the sobs finally ebbed did she speak.
“Feel better now?”
Degrienne turned away, her voice muffled. “You’re so obedient… you don’t even fight back… makes it hard to stay angry.”

She clenched a handful of Isabella’s clothes. “But dragging me back… that’s something I’ll never forgive.”
Isabella said nothing.
She knew full well: even if she hadn’t chased after her that night, with Lady Catherine’s awareness, Degrienne would never have escaped anyway.

But explanations meant nothing. If it made things easier, let her hate her.
“If I really give in one day…” Degrienne suddenly growled through gritted teeth, “then just get ready to ** me every day!”
Unexpectedly, Isabella actually leaned down, red lips parting as she slipped out her tongue.

“We can start right now.”
Her tongue shimmered wetly under the moonlight.
“P-Perv!” Degrienne jolted upright like she’d been shocked, the tips of her ears burning red.

She scrambled off the bed in a panic, bolting toward the door without looking back.
“Shall I escort you?” Isabella’s voice came from behind.
“No need!” Degrienne slammed the door hard.

The room fell quiet.
Isabella sat alone on the rumpled bed, eyes falling to the deep bite marks on her collarbone—still warm with Degrienne’s lingering touch.
Her gaze flickered—then stilled.

Elsewhere, in the maid dormitory—
Degrienne locked the door tight and summoned her system interface.
A crimson screen unfolded before her eyes:

【Host】: Degrienne Lilith
【Desire Points】: 30 (gained during PUA abuse)
【Available Infusions】: 1. Lightning Induction Body Tempering Technique (Advanced)
“Spend 10 first,” she murmured, tapping the technique’s progression option.
Leave 20 in reserve—just enough not to raise suspicion with a sudden power spike, but sufficient to deal with emergencies.

The system’s narration echoed coldly:
【Year 1】
You train bitterly in your dorm. Progress is slow.
After a year, lightning seeps into your bones.
Every breath releases crackling sparks.
Your silver hair begins to flutter even without wind.
【Year 5】
The blood-colored lightning serpent swells into a python through your meridians.
When you strike, the wind tears, and a towering tree collapses on impact.

【Year 10】
After a decade of cultivation, a condensed thunderball forms in your palm.
Targets twenty meters away are blasted to dust.
You finally possess ranged attack capabilities.
Simulation complete!
Lightning Induction Body Tempering Technique: Advanced → Perfected!
Degrienne’s eyes snapped open. Lightning flickered between her fingers.

Her current strength: 1,500 pounds of force in a single arm.
Lightning-body duration: extended to 30 minutes.
Thunderballs: five consecutive launches.
Her cultivation was still only Body Tempering Tier Eight—but her combat ability could rival average Postnatal Tier Nine practitioners.
Still, that was merely on par with the weakest maids in the castle.

“The Forbidden Chamber…” Her eyes pierced the walls, settling on that small, ominous door.
Lightning danced on her fingertips in the dark.
Catherine seemed to be out. Now was the perfect chance.

Last time, the gargoyle nearly killed her. But now?
A mere Postnatal Tier Seven guardian… was no longer a threat.
Degrienne rose to leave—but her eye caught on the crimson stain still marking the bedsheet.

Her fingers instinctively brushed her lower abdomen. The memory of Catherine’s violent indulgence still clung to her skin.
The thrill of advancement was instantly crushed by a wave of hatred—
She had to escape…

She had to kill her.
Degrienne clenched her fists, red lightning seething between her knuckles.
She slipped into the shadows, drawing close to the black door of the forbidden chamber—

When—
“Well, well… isn’t that my darling Degrienne?”
A lazy voice purred from behind. All the blood in her body froze.

She turned stiffly.
Catherine leaned against a column, dark red gown cascading like solidified blood.
“Back to your usual self, hmm?”

In the blink of an eye, Catherine had pulled her into an embrace, icy fingers pinching her cheek.
“You scared me half to death with your silent act earlier.”
Degrienne flung up her hand—lightning ball forming instantly in her palm!

“Mmm…”
Catherine casually took her sparking fingers into her mouth. Her red eyes narrowed in delight.
“Tingly… and numb… how lovely.”

Her tongue dragged deliberately across Degrienne’s fingertip. “A new trick? My sweet little Degrienne is amazing~”
Degrienne tried to pull her hand back—but her wrist was held firm.
Just when she braced for punishment, Catherine suddenly released her.

“As a reward… I’ll allow you a little trip into the city today.”
Degrienne froze, barely able to believe what she’d heard.
She’d thought she’d be imprisoned in this cursed castle forever—yet now she was being permitted to go outside?

“The vampire city…” she muttered.
She despised their kind—but observing their society firsthand could be invaluable for future revenge.
“What wicked little schemes are you plotting now?”

Catherine abruptly scooped her up, cold lips brushing her forehead.
“Remember—try to run, and…”
Her fangs grazed Degrienne’s earlobe. “I’ll forge you a solid silver cage… and hang you in the palace every day.”

Before she could reply, she was already being carried down the hallway.
“Go to the main hall and pick a maid to accompany you, my dear.”
