In front of C?u D?ng’s villa, a crowd of neighbors gathered in awe — murmuring, pointing, gasping. Before their very eyes stood a mythical masterpiece made real, glowing eerily under the clash of night and day.

  Inside the living room of Mr. Tài’s villa next door, the air was thick with fear. Anxiety filled every corner, every breath. C?u D?ng and M? Linh sat frozen on the sofa, faces drained of all color. They had just seen the spirits of the younger sister and brother-in-law they had once betrayed — now standing once again in the frost-covered courtyard, shrouded in mist.

  Professor Charles laid a heavy ancient tome on the table, his voice grave and deliberate:

  – “Just before the commotion, I was reading this passage… It speaks of a demon possessing three powers at once: space, time, and black fire with subzero heat. These three cannot coexist within any other being. The Demon King Satan himself sealed this creature in the Infernal Abyss a thousand years ago. If we’re seeing these powers now… it means he’s been set free.”

  The room fell silent — pale faces, trembling hands, pounding hearts. Deep immediately leaned forward, voice sharp with tension:

  – “So who exactly is this demon? Where did he come from?”

  Professor Charles turned another brittle page, his hand shaking slightly.

  – “He was not born of parents. He is the Black Diamond itself — crystallized from the dark core of the planet of Shadows. That world is ruled by the Demon King Satan and lies opposite the Milky Way, across from the solar system where Earth resides.”

  Tu?n gasped, stammering:

  – “That… that’s the Andromeda Galaxy…”

  The professor nodded solemnly.

  – “Exactly. The demons dwell on a planet whose orbit defies logic. Its surface is covered in endless vortex storms, swirling like colossal red eyes watching the universe. Each storm is an eternal cyclone — with winds and pressure fierce enough to tear apart any object that dares approach.”

  He continued, his voice low, resonant:

  – “It’s said that only mysterious dimensional gates allow the inhabitants to pass through the planet’s violent atmosphere. Any conventional entry… would be annihilated within seconds.”

  Ti?n wiped the sweat from his forehead, his voice trembling:

  – “So… they really exist. They’re living on a planet just like ours…”

  Professor Charles turned one last page, his tone slowing as if weighed by fate.

  – “The text also states: the demon is male. But the universe always maintains balance between yin and yang — which means… there exists a female counterpart identical to him.”

  At that, Mr. Tài turned sharply toward C?u D?ng, his face ghostly white:

  – “So there are two of them? Not one? D?ng, what on earth did you do to provoke these beings?”

  C?u D?ng shook his head frantically, his voice breaking:

  – “I… I don’t know… I’ve never even seen what they look like! How could I have offended them?”

  The late-night dinner in the seaside-view villa had come to an end. Erion reclined on the sofa, one hand gently brushing through Trang’s silky hair. She was fast asleep, her face calm and serene as she rested her head on his lap. Through the Black Crystal Mirror, the image of Mr. Tài’s living room appeared vividly before them. His deep voice drifted softly, like the whisper of wind:

  — “Of course, we are real… but our power is far more terrifying than what that book describes.”

  ---

  In the warmly lit living room, Professor Charles’ trembling hands turned another page. His tone grew tense and severe:

  – “That demon possesses strength equal to that of the Demon King Satan himself. Yet his nature is twisted — perverse, grotesque. His attacks leave behind haunting psychological torment… scars that can never fade.”

  Deep immediately snapped toward C?u D?ng and M? Linh, his tone sharp and accusing:

  – “Then that girl, Anh ?ào — the one who kept screaming that her body was melting like candle wax — and Mrs. Linh, who saw her food turn into crawling maggots… was that all his doing?”

  Tu?n’s eyes widened as the memories came flooding back.

  – “My fiancée, My… she once went into hysterics, saying she saw worms burrowing through her skin. Don’t tell me… that was him too?!”

  Ti?n turned to Professor Charles, cold sweat dripping down his face.

  – “You said earlier that he was imprisoned by the Demon King Satan for a thousand years in the Infernal Abyss… so does that mean Satan truly exists?”

  The professor nodded gravely, his voice low and deliberate:

  – “Yes. The book states they inhabit an independent planet — a civilization far more advanced than ours.”

  At that, Mrs. Nga clutched Mr. Tài’s hand tightly, her voice trembling, almost breaking:

  – “Oh my god… then what will Mr. D?ng’s family do now… how can they face a real demon?”

  Meanwhile, C?u D?ng and his family sat drenched in sweat, limbs frozen and pale. No matter how hard they tried to think, they couldn’t understand when — or how — they had ever incurred the wrath of such a monstrous being…

  Did you know this text is from a different site? Read the official version to support the creator.

  Professor Charles turned to the next page, his voice lowering into a somber tone:

  – “Humans often believe that Hell and demons dwell deep beneath the Earth, but that is not true. In reality, Hell exists on a distant planet — an independent realm whose surface area is vastly greater than Earth’s.”

  – “That entire planet is engulfed in eternal darkness, where colossal storms rage like the red scars of Jupiter, endlessly tearing through its gloomy atmosphere.”

  – “Hell is a sovereign nation, and its capital city is a towering fortress — royal palaces stretching for thousands of miles, with dark, majestic architecture forged from the ashes of dead stars.”

  – “Their civilization is not inferior to humankind — in fact, it surpasses ours, blending the cold precision of advanced machinery with the ancient power of magic. There, demons do not live as savages but within a structured society — ruled by hierarchy, bound by cruel laws, where the strong reign supreme and the weak are forced to kneel.”

  Deep wiped the sweat from his brow, his voice trembling with disbelief:

  – “All my life, I thought Hell was buried beneath the ground…”

  Tu?n leaned closer, his tone resolute:

  – “Then they must exist parallel to the human world. That’s the only explanation for why they’ve targeted Mr. D?ng’s family.”

  Professor Charles nodded in agreement:

  – “Exactly. Especially the one known as the ‘Black Diamond.’ When he reveals his power, it means he is physically present on Earth.”

  He continued reading aloud from the book:

  – “The ice people see is actually born from fire. He and his female counterpart possess the ability to reverse the laws of physics.”

  Hi?u, Mr. Tài’s son, slapped his forehead as realization struck him:

  – “No wonder the hotter it gets, the thicker and colder the ice becomes…”

  Professor Charles nodded approvingly:

  – “Precisely — that is what makes it unique. A power that defies the very laws of the universe.”

  ---

  Meanwhile, at the Bình Chánh Headquarters, the remaining factions were observing everything through a network of military satellites merged with dark magic.

  Din smirked with a wicked grin:

  – “That’s not all, Professor. You’ll soon have to deal with vampires, sorcerers, elves, ancient beasts, and witches… take your time unraveling that.”

  Yin sneered, her tone dripping with mockery:

  – “Speaking of witches, Count… when will those kids finally set foot in Saigon?”

  Din answered without hesitation:

  – “The night after tomorrow.”

  The Grand Thái S? inhaled deeply, savoring the lavender perfume she had crafted herself, then smiled faintly:

  – “Then on Sunday night, we must invite Erion back to the Gothic Mansion… to properly greet our new neighbors.”

  Arian glanced toward the staircase:

  – “Trúc Di?n and Mr. V?nh turned in early tonight, but I’ve recorded everything. I’ll show it to them tomorrow.”

  In one corner, a few mischievous young demons were munching on donuts. One of them spoke with a cheeky grin:

  – “We also heard that Chen’s joining this time. It’s gonna be a real party!”

  Sinister laughter echoed through the grand hall — a chilling omen that a brutal new game was about to begin…

  In a small, dimly lit house tucked deep within a narrow alley, the mezzanine level remained silent and shrouded in darkness. Huy had just stepped out of the bathroom when his phone on the table suddenly lit up with a message from Th?:

  – “The mansion is in broad daylight now — there’s sunlight, white clouds, and a bright blue sky. But the sunlight only exists within the mansion’s boundaries. Both the sun and the moon are visible at the same time. Professor Charles is analyzing the demon... everyone is terrified after hearing about it.”

  Reading the message, Huy’s heart pounded violently. He bolted downstairs and knocked on his parents’ door.

  Panting, he blurted out:

  – “Dad! Mom! Something’s happening! Th? just texted me…”

  Mr. Tín, rubbing his sleepy eyes, cracked open the door and grumbled irritably:

  – “What’s all this yelling in the middle of the night, boy?”

  Huy, pale and trembling, stammered:

  – “Th? said... the mansion turned into daytime. There’s sunlight in the middle of the night, but strangely, the light doesn’t go beyond the property line!”

  Mrs. Nguy?t stepped out, tying up her messy hair with one hand:

  – “What kind of strange thing is that? Oh Lord, I don’t know what trouble that family’s gotten themselves into…”

  Huy’s voice quivered as he continued:

  – “Th? also said that the professor was analyzing some kind of demon… He’s terrifying — everyone who heard about him was horrified.”

  Mr. Tín glanced at the clock on the wall and sighed:

  – “It’s almost four in the morning. Fine, around seven we’ll head over there and see what’s going on.”

  Mrs. Nguy?t clasped her hands tightly, her face full of worry:

  – “I just don’t understand what kind of demon could have such strange powers. Even our entire centipede spirit clan’s never seen anything like this…”

  ---

  Meanwhile, in a villa in District 7, the entire household was asleep — except for Anh Tú, who sat alone in his room. Before him hovered a magical orb reflecting the image of his wife’s family mansion.

  He smirked bitterly, his tone dripping with resentment:

  – “Your family… especially you. You looked down on my feelings, trapped me, just to seize this fortune.”

  Clenching his fists, his eyes glowed faintly with a violet hue — the mark of a heartbroken spirit. His voice dropped to a venomous whisper:

  – “I loved you… loved your family as my own. Fine then, wait for the court date. In this divorce… neither you nor your family will get a single cent.”

  – “Be ready to face retribution — the punishment for every sin your family has ever committed. They won’t rest until everything comes to light.”

  The magical orb flickered coldly, casting an eerie light over Anh Tú’s face — revealing a twisted smile of hatred and vengeance…

  In front of the brightest mansion in the entire neighborhood, a crowd of curious onlookers had gathered — their chatter filled the air as frustration began to rise among them. No one could manage to take a single clear picture.

  A young man scratched his head in exasperation, his tone sharp:

  – “This is driving me crazy! Why can’t I take a single decent photo? Don’t tell me my phone’s broken!”

  Beside him, a young woman holding a brand-new phone scowled:

  – “My phone cost nearly a fortune — top-of-the-line camera — yet I can’t even start a live stream. What’s going on?!”

  The commotion outside grew louder and more chaotic, yet inside Mr. Tài’s mansion, the tension had taken a darker, heavier form.

  Hi?u glanced out the window and frowned slightly:

  – “The neighbors still haven’t gone to bed. They’re crowding in front of Uncle D?ng’s mansion.”

  Mr. Tài turned toward C?u D?ng, his tone deep and measured:

  – “Think carefully… Have you ever offended anyone?”

  Professor Charles nodded, his gaze serious:

  – “Even demons follow their own codes and laws. They don’t act without reason.”

  Suddenly, Deep seemed to recall something and blurted out:

  – “Tu?n’s fiancée, My — she insulted Mr. D?ng’s niece that night… and right after that, she began seeing hallucinations.”

  Ti?n quickly interjected, his tone urgent:

  – “That’s true! We even sent someone to her old place to apologize, but her landlady said she’d been evicted because she couldn’t pay her rent.”

  Professor Charles furrowed his brow and pressed on:

  – “And what about her now? Does she still experience hallucinations?”

  Tu?n answered immediately, worry flashing in his eyes:

  – “At first, she said insects were burrowing under her skin — eating her alive. Then it stopped for a while. But later, she claimed she could hear the paintings laughing at her. It didn’t last long either, and since then… nothing.”

  Dì T? trembled slightly as she added:

  – “Anh ?ào was the same… except it wasn’t the paintings — she heard the dolls talking.”

  Mrs. Nga, her voice tinged with curiosity and unease, asked:

  – “So, everyone who saw those hallucinations… they all mistreated that girl?”

  The entire room fell into a suffocating silence. Every person involved averted their gaze, their faces pale with guilt. Professor Charles fixed his piercing eyes on C?u D?ng, his tone firm and commanding:

  – “Tell me everything about that niece. I have a strong feeling… she’s the key to all of this.”

  Everyone exchanged uneasy glances before their eyes slowly turned toward C?u D?ng. Their hearts tightened — the truth they had all feared was finally about to be revealed.
