Rain lashed against the triple-paned glass of the ninety-eighth floor. Inside, Imtiaz did not look up from his holographic interface. Green and blue lines of code reflected in his dark eyes, calculating risk metrics with clinical speed. Millions of digital dollars shifted under his commands, moving through the artificial markets of the city. Success in 'The World of Luck' was not a matter of chance; it was a matter of mathematics. Suddenly, the system flickered. Black screens replaced his active trading terminals, wiping out three million dollars in unrealized gains. Coldly, Imtiaz tapped the glass console. Nothing responded. System diagnostics showed a complete localized override, a security breach that should have been impossible in this high-tier penthouse. A mechanical chime echoed from the private elevator foyer. Sliding doors parted with a soft hiss, revealing a figure clad in matte-black tactical gear. Standing there was a courier, his face hidden behind a polarized visor that reflected the neon glare of the city below. Silent and efficient, the courier stepped forward and placed a sleek, pitch-black box on the center of the glass desk. Without a word, the courier bowed slightly, turned, and disappeared back into the elevator. Metal scraped against glass as Imtiaz pulled the object closer. It was heavy, cold to the touch, and made of a seamless alloy that absorbed the room's ambient light. No visible seams, hinges, or screws interrupted its surface. Running a hand over the top, Imtiaz felt a sharp prick at his fingertip. Red laser lines instantly flared across the black metal, scanning his hand. "DNA mismatch," a synthesized, genderless voice chimed from the box. "Three distinct biological keys required." Three distinct keys. Blood keys. Taking a deep breath, Imtiaz stared at the box, knowing exactly whose blood it demanded. Safder arrived forty minutes later, his heavy boots squeaking against the polished marble floor. Rainwater dripped from the hem of his canvas jacket, pooling around his feet. "You haven't changed, Imtiaz," Safder said, his voice flat and devoid of warmth. Imtiaz did not rise to greet him. Lifting his chin, Imtiaz pointed toward the wet floor. "And you still refuse to use an umbrella," Imtiaz replied. Heavy, dragging footsteps brought Safder closer to the desk. He pulled back his sleeve, exposing thick, jagged scars running from his wrist up to his forearm. These were the physical reminders of their childhood abandonment, the brutal years spent surviving in the lower districts while Imtiaz climbed the corporate ladder. A loud crash cut through the quiet tension of the room. Wood splintered as the penthouse double doors flew open, bounced off the walls, and settled on their hinges. "Missed me?" a loud, cheerful voice boomed. Hasan stood in the doorway, a reckless grin plastered across his face, his leather jacket drenched and a cigarette dangling unlit from his lips. Gold rings glinted on his fingers as he ran a hand through his messy hair. "We aren't here for a family reunion, Hasan," Safder muttered, his shoulders tensing. Safder scoffed, turning his back on his youngest brother. "Shut up, Safder," Hasan laughed, walking straight to the desk and tossing a wet lighter onto the glass. Stepping forward, Hasan leaned his weight on the desk, looking down at the black box. Dark, heavy silence descended upon the three brothers. "Look at this high-tech junk," Hasan said, tapping his knuckle against the alloy. Imtiaz pointed to the small, circular indentations on the top of the box. "It requires a biological match from all three of us," Imtiaz explained. "Of course our dead father would leave us something that requires us to bleed," Hasan laughed bitterly. Safder stepped closer, his scarred arm trembling slightly. "Why should we trust anything he left behind?" Safder asked. Because we have no choice, Imtiaz thought, though he kept his voice perfectly calm. "Our father's estate controlled thirty percent of the city's infrastructure," Imtiaz said. "If this box is what I think it is, ignoring it means our financial ruin, and likely our physical elimination." Hasan shrugged, pulling a pocketknife from his jeans. "Let's get it over with," Hasan said. With a swift, practiced motion, Hasan sliced the pad of his thumb and pressed it against the first circular sensor. Yellow light flared beneath his skin, accompanied by a soft, mechanical hum. Safder hesitated, looking at his scarred wrist, then at Imtiaz's cold, calculating eyes. Pressing his own thumb against a blade, Safder stepped up and held his bleeding finger to the second sensor. Blue light joined the yellow. Imtiaz did not hesitate. Using a small lancet from his desk drawer, he pricked his index finger and placed it on the final sensor. Green light exploded from the box, merging with the blue and yellow to form a blinding white beam. Suddenly, the box clicked. A low, rhythmic ticking sound began to echo from within the metal structure. Light projected upward, stitching together a three-dimensional holographic image in the center of the room. Standing before them was the towering, stern figure of their deceased father, looking exactly as he had the day he vanished. Cold, gray eyes swept over his three sons, his digital projection possessing a chilling lifelike quality. "If you are watching this, it means you have finally put aside your pathetic petty differences," the hologram spoke. "Or, more likely, Imtiaz forced you here through manipulation." Hasan spat on the floor, his grin completely gone. "You were always failures individually," the projection continued, its voice echoing with mechanical malice. "But together, your combined cognitive algorithms, physical resilience, and reckless daring might actually survive what comes next." Safder took a step toward the projection, his fists clenched. "You abandoned us!" Safder yelled at the empty light. "Do not waste your breath speaking to a pre-recorded message," Imtiaz said, his voice cutting through Safder's anger. "Listen to what he is actually saying." "Your lives are now forfeit," the holographic father declared, his image flickering slightly as the transmission neared its end. "The moment your blood touched the keypads, a lethal, slow-acting neurotoxin was introduced into your systems through the micro-needles." Hasan gasped, dropping his pocketknife as his hand flew to his throat. Safder looked down at his thumb, where a tiny, purple puncture wound was already turning black. Even Imtiaz felt a cold sweat break out across his neck as his heart rate spiked. "The antidote is locked within this box," the hologram said, a cruel smile playing on the dead man's lips. "To unlock the compartments, you must complete the tasks sent to your personal terminals." "Fail, and the toxin will liquefy your internal organs." "Welcome to my final puzzle, boys." The holographic projection flickers out, replaced by a crimson digital countdown timer burned into the box's sleek metallic surface, showing exactly 72 hours left to live.
