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

In the dim chamber—

Catherine sat kneeling beside the sleeping Degrienne, her blood-red eyes filled with tenderness.
She carefully lifted that delicate little body, handling her like a fragile treasure.
……(redacted)

Catherine’s movements were impossibly gentle, as though even the faintest stir might wake the girl nestled in her arms.
After slipping her arms around Degrienne from behind and fastening the final clasp, she couldn’t help but rest her chin on that soft shoulder, inhaling deeply.
“Mmm… all my scent now…”

The sweetness of blood mingled with a girl’s natural fragrance, making Catherine’s fangs ache with longing.
She resisted the urge to bite, letting her lips gently brush against the skin of Degrienne’s nape instead.
The black gothic minidress had been the most work.

Catherine tied every ribbon with loving precision, smoothing out each ruffle as if adorning her favorite doll.
When the final lace choker had been properly adjusted, she stepped back and admired her masterpiece.
……(redacted)

“Even her fingers are so adorable…”
Finally, she gently scooped up the now fully dressed Degrienne and lay down, pulling her close.
Catherine lay on her side, holding the girl face-to-face, taking in her peaceful sleeping features.

Silver lashes cast soft shadows across her cheeks. Pink lips parted slightly with each breath, warm air brushing against Catherine’s skin.
“Good night, my little darling…” Catherine kissed her gently on the forehead, then closed her own eyes.
Degrienne, still deep in sleep, instinctively burrowed closer, her forehead resting against Catherine’s collarbone.

Her slender arms circled Catherine’s waist, as if grasping for safety.
Catherine, still dreaming, tightened her embrace as if by reflex—completely enveloping the girl’s small frame.
……(redacted)
“Mmm… no, not yet…” Catherine murmured sleepily, her voice husky and languid. “Can’t eat her yet… later…”

Strangely, Degrienne actually stopped moving—simply pressed her face deeper into Catherine’s chest.
Their unconscious bodies slowly fell into rhythm, breath syncing as they drifted into a deeper slumber.
This was the closest they had ever come… to tenderness.

But the peace didn’t last long.
In her dream, Degrienne returned to that rain-soaked night she could never forget.
A boy of eight clutched his six-year-old sister’s hand, stumbling through a burning street in chaos.

Behind them, towers of flame lit the sky. The vampires’ shrill laughter echoed in the night.
Their mother’s pale face flickered in the lightning: “Zhao Zhao! Take your sister and run! Don’t look back!”
“Mom!” she screamed, but could only watch as a burning piece of debris crashed from the sky—

The dream cut abruptly to the orphanage courtyard.
At ten, she was hiding behind a tree, watching her sister shine on the martial arts platform.
With a graceful spinning kick, the girl sent numbers jumping wildly on the test device, drawing gasps from the surrounding teachers.

“A genius! Already Postnatal at eight?”
“The Chu Clan’s birthing a dragon!”
Degrienne lowered her gaze to her scraped palms.

She’d been secretly training for three months… yet couldn’t even activate the most basic strength sensor.
She’d tried everything—even sneaking sips from her sister’s leftover herbal bathwater—only to break out in an itchy rash.
That night, she cried under the covers for hours.

Eventually, she tore the "Vampire Weakness Analysis" column ◆ Nоvеlіgһt ◆ (Only on Nоvеlіgһt) from a martial arts magazine and pasted it into her diary.
Then the dream shifted again.
At twelve, she stood on the school rooftop, staring at a glowing blue interface only she could see:

【Lifespan Infusion System Activated】
【Kill enemies to gain lifespan】
【Infuse martial arts to advance cultivation】

The first to die by her hand was a lone vampire scout.
When the rusted fruit knife pierced his heart, she trembled violently—but pressed down hard on his flailing body until the system popped up:
【Gained Temporary Lifespan: 37 years】
Then memories came in a blur:

Her exceptional acceptance into the martial academy, her sister’s joyful embrace, her first kill on a real battlefield—a viscount-level vampire—and the day she was granted the title Tian Zhao.
It all froze on one image: standing before the world rift, sword in hand, slicing through the sky to seal the portal that threatened humanity.
But in the end… she still lost.

Lost to that tall, dark-red figure.
“No… no—!” Degrienne twisted in her sleep.
She dreamt of her defeat—Catherine’s fangs piercing her neck.

Then waking to find she had become this—silver-haired, red-eyed, a loli in a frilly dress.
“Mmgh!” Her eyes snapped open. Her chest rose and fell in ragged gasps.
Anger and humiliation from the dream still pounded in her chest—but then she felt it.

That cold touch around her waist—
Catherine had wrapped around her, chin resting atop her head.
In sleep, the vampire’s usual danger had vanished. She almost looked… (redacted)?

Degrienne’s body went rigid.
She should push her away—this vampire was the reason for everything.
The one who had turned her into this.

And yet… Catherine’s embrace was so warm.
That tight, enclosing grip brought back the distant memory of her mother holding her during nightmares.
What the hell am I supposed to do… she wept silently, her small frame trembling in the vampire’s arms.

Hatred and dependence tore at her chest—and then, a wild thought surged forward:
What if I kill her now? While she’s asleep…
But the idea dissolved almost instantly.

What a joke. Even if Catherine was completely defenseless, with her current suppressed strength, she probably couldn’t even scratch her.
The realization choked her with frustration.
……(redacted)

“Mmm～” Catherine let out a sweet, sticky moan. Her crimson eyes snapped open, glowing eerily in the dark.
Only then did Degrienne realize what she had just done.
Her face turned bright red—(redacted).

Shit. That damned vampire was going to lose her mind.
And for the first time… Degrienne began to regret it.
