Inside the Gothic mansion's eerily quiet living room, a sharp electronic beep sliced through the tension. Din's encrypted laptop screen flared red with an alert:

  – “Movement detected: Black Cadillac — Departed from Royal Satan Headquarters, en route to Bình Th?nh District.”

  Din’s eyes widened. He instantly opened a secured comm channel, his voice dropping into a low register:

  – “General… a black Cadillac just left Satan’s headquarters. According to satellite trajectory, it’s heading straight for Bình Th?nh.”

  Erion’s eyes—normally masked by his humanoid form—flashed a fierce ruby-red, the telltale sign of a predator sensing its prey.

  – “It’s her…” he hissed, each word etched in steel.

  – “Bring the laptop. We’re moving out.”

  He swiftly donned a short storm-grey overcoat, the high collar flaring like a war banner. With Din and Yin, he strode out of the mansion. Sunset’s soft orange hue glimmered on the mansion’s cold grey stone steps, painting streaks of silent tension.

  Din issued a sharp command to the lesser demons:

  – “Secure the estate. Eyes on the thawing mansion across the street. Report anything unusual.”

  – “Understood, Count!” the demons replied in unison.

  The trio entered a sleek black Bentley. The doors opened as if bowing to their rank—three Sovereign-class beings of the underworld.

  Yin took the wheel. Din and Erion occupied the back seats. Din’s laptop lit up with the Black Diamond crest, fully synced to the organization’s private satellite grid.

  – “Target locked. We’re tracking the Cadillac in real time. This time...” Din glanced at Erion, “…we're closing in.”

  Erion turned his face slightly, amber eyes as deep as a bottomless abyss. He clenched a fist, muttering through gritted teeth:

  – “There is only one Sovereign-Class Black Diamond in this universe. And that… is me.”

  Yin chuckled softly, eyes catching Erion’s through the rearview mirror:

  – “But she is destiny itself—crafted by the universe to wait on Earth for you, General.”

  Erion stared out the window, voice flat:

  – “I don’t care. I’ll make her kneel… and beg for forgiveness.”

  Din sighed, though his lips curled into a smirk:

  – “Let’s see if you can do that. Or maybe… you’ll be the one on your knees.”

  Yin burst out laughing as he took the turn:

  – “Well, you do have to kneel to propose, don’t you?”

  Erion growled:

  – “Another word, and I swear I’ll freeze this damn car into an ice coffin.”

  ---

  Meanwhile, in a narrow alley near the old rental neighborhood in Bình Th?nh, a polished black Cadillac gently pulled over to the worn sidewalk, now faded with the footprints of time. The soft golden hour cast its glow across cracked cement tiles, each one holding fragments of forgotten days.

  Trang stepped out—dressed in modern nobility: a white ruffled high-collar blouse, form-fitting black leather leggings, high-heeled boots, and a smoky charcoal Italian leather crossbody bag.

  A breeze swept through the Saigon dusk, tugging gently at her silky black hair, brushing across her golden-toned skin. Her crimson eyes glimmered with memories laced in pain.

  Behind her, two elite bodyguards in black suits scanned the area with clinical precision. One tapped his earpiece but didn’t disturb her solemn pace.

  She walked the pavement silently, each step echoing on weathered ground—the same spot where she once sold street snacks and milk tea to elementary kids. Where ?ng Nhan helped her daily. Where H?ng Nhung often brought food to keep her company.

  – “This was my sky… five years of humble peace. Back then, everything felt simple… and real.”

  She murmured silently.

  Her fingers traced the familiar cement wall—the exact place they used to set up a plastic table to eat, chat, laugh, and cry. The memories of two souls—now revealed as her royal father and sister-in-law—still lingered.

  – “This was where I parked the snack cart. That was the ice chest for herbal tea…” Trang whispered to herself.

  Each breath she took pulled memories from the depths of her soul. Despite the awakening of her true bloodline, her new wealth and power… the pain of her past never truly left.

  In the distance, sunlight glinted off the Cadillac’s windshield like fate itself silently watching her.

  Unseen and not far behind… Erion’s Bentley turned into a nearby ward, tracking every move—guided by his satellite’s unwavering gaze.

  The sleek black Bentley glided to a stop—ten meters behind the Cadillac—right where the dying sunlight frayed like strands of gold. Two elite bodyguards stood watch at the rear, both demon-warriors trained under a classified program. In unison, they opened the doors, hands gripping high-frequency pulse-laser weapons, eyes scanning the perimeter like apex predators sensing a rival presence.

  The door opened.

  Erion stepped out first.

  In his humanoid disguise—light-toned skin, tall European build—his amber eyes flared with ferocity the moment he saw her. The one he'd long sought to confront. She stood no more than ten meters away.

  Din and Yin followed, both Sovereign-class vampires. Their eyes were sharp, calculating, each step carrying the weight of an ancient storm.

  ---

  Ahead of them, Trang stood motionless, like a statue carved into the dusk. Her white high-collared blouse danced in the breeze. Her long, silky black hair flowed like a midnight river behind her. She knew they had arrived.

  But she didn’t turn.

  Her voice rang out—cold, bottomless—as if gravity itself dipped for a second:

  – “So, you’ve come… I am the only Black Diamond the universe ever forged.”

  That moment made Erion freeze. Then he chuckled—a half-smile laced with mockery:

  – “A girl… dares challenge me for a Sovereign title? Don’t blame me if I don’t go easy—just because you're a woman.”

  His eyes sharpened like blades. As he stepped forward, waves of ancient frost and killing intent pulsed from his core—born of the blackened center of the universe itself.

  ---

  Behind him, Din leaned slightly toward Yin, whispering:

  – “So… what now? If they fight here, we’re going viral. Front-page news, full social media coverage, maybe even trending on TikTok.”

  Yin frowned, voice dry:

  – “I’m more worried whether this entire district survives…”

  If you stumble upon this narrative on Amazon, be aware that it has been stolen from Royal Road. Please report it.

  Din rubbed his forehead and sighed:

  – “We’ll probably get arrested… for destruction of urban infrastructure.”

  ---

  Dozens of kilometers away, inside the command center of the Satan Royal Headquarters in Bình Chánh, screens curved across 180 degrees filled the glass room with light. Every movement was being monitored through the Satanic Kingdom’s private satellite system.

  Satan stood motionless before the central screen, arms crossed, amber-gold eyes fixed forward. Behind him were Arian and H?ng Nhung, both visibly tense.

  Arian stepped forward, voice urgent:

  – “Father… They’ve made contact. Princess Trang and Erion. Should we… intervene?”

  Satan didn’t turn. His voice flowed like wind brushing through an autumn bamboo grove:

  – “No need… This is what I intended. Everything is aligning… exactly as fate and my strategy demand.”

  H?ng Nhung clenched her fists. Her unease was etched in her expression. She alone saw it clearly: since the day Trang awakened—she had no longer been the kind-hearted, gentle girl they once knew.

  The final rays of sunlight draped the alley like silk, painting everything in hues of gold. There, Trang stood in quiet defiance—until, slowly, she turned.

  The slanted light kissed her sculpted face—bronzed and radiant—with long black hair swaying gently in the breeze. But it was her eyes that commanded the world.

  Her left eye bore the sigil of Space.

  Her right, the ancient spiral of Time.

  Twin crimson irises—glowing with sovereignty and solitude—swirled like blood-born galaxies. She was cloaked in noble elegance: a white ruffled blouse, black leather leggings, and curves shaped with divine symmetry. Cold. Regal. Dangerous.

  ---

  Erion froze.

  His heartbeat—usually non-existent—slammed into his chest, erratic, unfamiliar. He, a deathless being born from the Black Core of the Dark Star, found himself staring at a mirror… made flesh.

  The aura. The eyes. The skin. The anatomy.

  Everything.

  She was… him. In another form.

  ---

  – “We’re the same,” Trang said—her voice calm, unwavering, piercing through him like a spear of truth.

  – “The only difference… is the core of the planet that forged us.”

  ---

  She stepped forward. Each stride reverberated across the unseen space between them—as though the universe itself trembled.

  And then—

  Her right wrist flared with ancient magic. A spinning circle of time engraved in glowing runes burst to life, silver-violet energy cascading in all directions.

  But in that instant—

  Her expression faltered.

  Her eyes darkened. Her skin paled.

  Her breath caught in a fragile gasp.

  – “What… what’s happening to me?!”

  Her legs buckled. Her body collapsed, consciousness fading into darkness.

  ---

  Unconsciousness.

  But in the hazy drift of collapsing thought, she felt something.

  A pair of arms.

  Strong. Warm. Anchoring her.

  An embrace… like it had waited lifetimes for this moment.

  ---

  The two elite bodyguards behind her surged forward, eyes flaring with duty and protective instinct.

  But Din raised a hand to halt them:

  – “Stand down. Don’t interfere.”

  His voice was firm—unyielding.

  The bodyguards tightened their grips on their weapons… but held their ground.

  Yin stepped forward, eyes focused on the unconscious girl in Erion’s arms. His voice was low and analytical:

  – “Her power just awakened. Her body isn’t ready to handle it yet.”

  – “She needs time… to learn control.”

  ---

  And still, Erion said nothing.

  He simply stared down at the girl sleeping in his arms—the same girl who moments before had challenged him with eyes like twin crimson stars.

  Her face, even in sleep, held a sorrow carved deep into the soul. Her lips barely parted, brows faintly furrowed—as though even in unconsciousness, she carried the pain of entire worlds.

  His gaze softened.

  – “Like me… but not me. Are you… my destiny?”

  A feeling bloomed inside him—alien, unnamed, and utterly unstoppable.

  The air began to stir.

  Onlookers in the alley—once few and indifferent—now paused. Eyes turned. Whispers rose. The weight of too many human gazes thickened the atmosphere.

  One of Satan’s royal bodyguards stepped forward, voice sharp and low:

  – “We need to extract immediately. Too many eyes.”

  Yin's mind was already spinning, his eyes flashing with ruthless clarity:

  – “We can’t bring her back to the Gothic Mansion. D?ng’s family and those damn exorcists would pick up on it immediately.”

  He looked at Erion.

  – “Take her to my estate. District 9. Secure. Isolated. No one breaches it.”

  Erion said nothing. Instead, he bent forward and lifted Trang into his arms—her body light, delicate, almost woven from starlit silk. She fit into his arms like destiny itself.

  Din and Yin moved swiftly, clearing the path.

  They loaded into the obsidian-black Bentley, Yin behind the wheel, Din riding shotgun. Behind them, the Cadillac—with Satan's royal guards—followed in solemn silence.

  ---

  Forty minutes later, as dusk spilled across the skyline of Saigon, their motorcade arrived at a hidden sanctuary.

  There, nestled within the modern chaos of District 9, stood a Qing Dynasty–style palace villa, a relic of imperial China reborn in steel and stone.

  Giant wooden gates, engraved with dragons and phoenixes, opened with a deep groan—revealing vampire guards in traditional Eight Banner uniforms. Their red eyes glowed under braided hair and steel blades, unmoving as statues.

  The air was cold. Heavy. As though this estate had been carved out of time itself.

  Yin stepped out first, his presence regal—like a prince returned to the Forbidden City. He led the way.

  The inner sanctum opened into a grand hall bathed in the golden glow of hanging silk lanterns. Carved dragons lined the walls, whispering of history. Every step was soaked in imperial solemnity.

  – “Place her on that velvet couch,” Yin ordered.

  Erion gently laid Trang on a luxurious black settee adorned with violet embroidery. She remained unconscious, yet her face was peaceful—cheeks slightly flushed, as though she sensed his touch even in sleep.

  Then—

  Her hands began to shimmer.

  Crimson veins of energy crawled across her skin—slithering like roots of magic rising from the earth.

  Yin narrowed his eyes:

  – “As I suspected. Her powers have awakened too quickly. The surge is overwhelming her.”

  – “She hasn’t learned control yet.”

  The two royal guards bowed deeply:

  – “We’ll remain by her side, not leaving a single step, until the Princess regains consciousness.”

  The tension in the room was cut by Din, who strolled over, hands in his pockets, smirking like a devil ready to poke the beast:

  – “By the way, who was it in the car just earlier that growled, ‘There’s only one Black Diamond Lord, and it’s ME’?”

  He cast Erion a sideways glance full of bite.

  Erion folded his arms, exhaled sharply, and looked away—visibly annoyed.

  Yin couldn’t help himself. A hand lifted to cover his mouth as a quiet laugh escaped:

  – “Said with such flair. But doing it... now that’s another matter.”

  Din chuckled and clapped Yin on the back:

  – “Maybe this time… our Supreme Commander is about to learn something important.”

  – “That even for an immortal... the heart may be the deadliest weakness.”

  ---

  In the middle of that vast, ancient chamber, Trang remained lost in dreams.

  But deep within her…

  A faint vibration had begun.

  The very first tremor of fate.

  A fate named Erion.

  He still tried to maintain his cold facade in front of the others, but his eyes—oh, those traitorous eyes—kept sneaking glances at her. Outwardly, he was calm. Stoic.

  But inside...

  A thousand-year storm had begun.

  And it was washing away ten centuries of solitude.

  The atmosphere inside Yin's villa remained still. Trang lay motionless amid a bed of royal purple silk, the final rays of sunset casting long shadows across her.

  Suddenly, Din’s phone rang. The caller ID: "Imp – Gothic Surveillance Post."

  He answered, voice calm and flat:

  “Report.”

  A frantic voice came through:

  – “My Lord, the target residence—the house of that man D?ng—has erupted with screaming. Our visual surveillance confirms: it's his wife and daughter.”

  A slow, wicked smile curled on Din’s lips:

  – “If Satan’s moved… then not even the gods can intervene. They’ve only one option left now—beg for mercy. Keep monitoring. I’ve got a feeling… that house is about to become a comedy stage.”

  He hung up and glanced at Erion.

  The commander was seated on a dark redwood chair carved with ancient pine and crane motifs. His amber eyes were unreadable but never strayed from Trang.

  She was still fast asleep, breathing softly. Her brows furrowed slightly—caught in a dream she couldn’t escape.

  Erion finally spoke, his voice low:

  – “That family… treated her like trash. An orphan—tossed out of her own home, her inheritance stolen…”

  Yin added grimly:

  – “And disrespected. Her love was mocked. She was humiliated instead of embraced.”

  Din looked over, intrigued:

  – “Say more.”

  Yin unlocked his phone and pulled up a video.

  It was a clip showing My, Tu?n’s fiancée, grabbing Trang by the hair and shoving her to the floor during the wedding of Anh ?ào—D?ng’s daughter. The video had been captured by a guest and posted online recently.

  – “Watch this. She was dragged, shoved down… in front of everyone. This was before she even awakened. But I still recognized her.”

  – “The comments say she’s a tomboy who had a quiet crush on Tu?n—My’s fiancé and a wealthy heiress. Apparently, jealousy took over.”

  Din scrolled through the replies, then read aloud:

  – “Even though she liked him, all she ever did was watch from a distance. She never interfered. Poor girl.”

  Erion shot up to his feet.

  His jaw clenched, and a cunning smirk formed on his sharp features as his silhouette stretched across the dragon-carved marble floor.

  – “Time to deliver one more blow… So they’ll learn what true etiquette means.”

  ---

  Meanwhile – At D?ng’s Mansion.

  The ice had melted. The once-frozen mansion was now flooded, its floors slick and glistening like a lake had broken free.

  Inside—chaos.

  Screams echoed from the living room and kitchen.

  – “HELP ME! My body’s melting! I’m dripping like a candle!”

  Anh ?ào curled up in the corner, her entire frame shaking violently. Her eyes were red with terror.

  – “Sweetheart, calm down! You look perfectly fine!”

  Anh Tú clutched his wife, eyes wild with panic.

  In the kitchen, M? Linh wailed, eyes glued to the dinner table:

  – “The chicken… the salad… WHY ARE THERE MAGGOTS CRAWLING ALL OVER?! I WON’T EAT THIS! I WON’T!”

  Anh Th? hugged her trembling mother tightly:

  – “Mom, you’re hallucinating! There’s nothing there! Please don’t be scared!”

  C?u D?ng stood frozen, pale and speechless.

  Anh Tú shouted:

  – “Dad! I’ve explained until my throat's dry! They won’t believe me! They’re seeing things—like a living nightmare!”

  Cries and howls layered on top of each other, bouncing off the walls and shattering the silence.

  Outside, neighbors began gathering.

  An elderly man muttered under his breath:

  – “Something’s not right with that family… not normal at all.”

  A young couple pulled over on their scooter, whispering:

  – “Looks haunted... like straight out of a horror movie.”

  A jogger slowed down, drawn by the noise:

  – “You’re not wrong. Only this house froze like the Arctic. It’s cursed for sure.”

  The air around the mansion thickened—oppressive, sinister.

  But only those watching from the shadows—far beyond the human eye—truly understood:

  This was no madness.

  This was no accident.

  This was the beginning of a spiritual war.

  And the first act…

  Had just begun.
