Reincarnated with a lucky draw system

[The dungeon core is a medium that stores the chaotic universe essence. With processing it can slowly be siphoned by beings to get stronger. Taking it directly risks being corrupted by the raw essence of the universe itself and becoming a monster. But considering the latent ability of Host's bloodline, Host should be fine.]

"Latent ability? What the fuck's that supposed to mean?" Aaron snapped, glaring at the dungeon core in his hand. Its glow pulsed like a living thing, wild energy buzzing through his fingers, tempting him to dive in. The system's cryptic-ass answer was grinding his gears, same as always.

[Host don't need to worry. Host will find out soon enough.]

"Fair point, you shady bastard," Aaron muttered, shoving the system's vague bullshit to the back of his mind. He turned to the Ice Queen, her pale face tight with fear, white hair catching the dungeon's icy light like a damn ghost. Her eyes screamed she'd do anything to not get smoked. Time to move this shit along.

"Come closer," Aaron ordered, voice low and sharp as a blade. The Ice Queen, desperate to save her ass, shuffled forward, her long white dress dragging across the frozen floor, the sound like whispers in the icy cavern.

Aaron bit his arm, blood welling up dark and thick, the metallic stench hitting the air like a punch. He forced her to drink, pressing his wrist to her lips. She choked, eyes wide, but swallowed the bitter hybrid blood. Then he sank his fangs into her neck, her sharp gasp echoing as his blood surged into her, kicking off the transformation. The system buzzed in his skull, like it was hyped for his ballsy play.

"Our work is done here, buddy," Aaron said to Flameborn, the dragon's scales glinting as it paced, itching for action. He opened a rift to the sanctuary, the air shimmering with raw power. He tried shoving the Ice Queen through, but she slammed into an invisible wall, stuck like a fly in a trap. "Tch, fucking figures," he growled. The dungeon core's energy was chaining her to this frozen shithole.

Trusting the system's word, Aaron eyed the core, its pulse daring him. "Here goes nothing." His hybrid teeth, sharp as fuck, crunched through it like brittle glass. Chaotic essence exploded in his mouth, raw and electric, like swallowing a goddamn thunderstorm. His veins burned, power surging, but his bloodline wrestled it down, keeping the corruption from turning him into some freakshow.

[If Host wants, I can siphon some dungeon core power and channel it to the sanctuary through your link.]

"What's the damn catch, you loan shark?" Aaron asked, squinting mentally. The system's deals always had strings, and he wasn't about to get played in this reincarnated grind.

[It reduces the strength you gain from the core, but it's more profitable long-term. It'll expand the sanctuary, creating a dungeon-like environment inside. More monsters will spawn naturally, loyal to you. The boss monster's beyond the sanctuary's power, though.]

"So I'm getting a dungeon in my sanctuary?" Aaron asked, making sure he wasn't misreading this shady-ass offer.

[Yes, Host. Monsters loyal to you. Sanctuary grows stronger, larger, more complete. Keep it up, it could evolve from an island to a full world.]

"Go for it," Aaron said, a warm tingle spreading in his gut, like his bloodline was chugging the core's power. The system was already at work, rerouting the essence to his sanctuary.

"Let's get the hell outta here. Time to check on Blade," Aaron said to Flameborn, ruffling the dragon's scales, its eager growl vibrating through the air. He scooped up the Ice Queen, still limp from the transformation, and stepped through the rift. This time, she passed through, the dungeon behind them crumbling—ice walls shattering, peaks collapsing like a dying beast, the air roaring with the sound of its death.

In the sanctuary, Aaron clocked changes instantly. Snowy patches crept over the north and south edges, frost weaving through the glowing grass like the system was carving a mini Ice Queen Dungeon. The air turned crisp, charged with new energy, like the sanctuary was leveling up right before his eyes.

"System, I'm feeling this warmth, but no damn power spike from the core," Aaron muttered, annoyed as hell.

[Your primogenitor bloodline is using the core's power to break the universe's curse, hastening your other bloodline's awakening. Host is advised to visit the vampire queen ASAP to guide you when you fully awaken, or you'll go on a killing spree.]

"A killing spree? What kinda batshit crazy talk is that?" Aaron barked, like the system was spouting the dumbest shit he'd ever heard in this reincarnated life.

[Because of the universe's soul curse, your hybrid attributes—blood obsession included—are bottled up. When it breaks, those instincts will flood you, overloading your control. You could drain a whole fucking country if you're not careful.]

"Alright, alright, quit the goddamn nagging," Aaron groaned, rubbing his temples, the warning sinking in like a bad quest log. "I'll see her once I sort this shit out. She probably knows more about my bloodline than I do." The stakes were real, and he wasn't about to let his hybrid side turn him into a mindless bloodsucker.

He glanced at the Ice Queen, still dead to the world, not yet transitioning. Blade, though, was almost done, his hybrid shift nearly complete. Aaron and Flameborn kept watch, eyes peeled for any fuck-ups, the sanctuary's hum a constant reminder of the power at play.

Hours later, Blade stirred, his golden pupils blazing like a beast's, muscles jacked up, taller frame radiating raw power, skin smoother but deadly as hell. He looked like a goddamn war machine, forged from Aaron's blood, ready to rip through anything.

"How you feeling after that?" Aaron asked, sizing up his first hybrid, impressed by the sheer menace rolling off him.

"Boss, I feel stronger. More alive than ever," Blade said, voice thick with energy, his loyalty locked in like a system-coded vow.

*Crack! Crack!* Blade tested his limits, shifting to full werewolf form on all fours. His eyes sharpened to slits, vibe turning feral, like a predator that could shred a city without breaking a sweat.

"Let's have a test run. Give me your best shot," Aaron said, rolling up his sleeves with a cocky grin, itching to see what his creation could do.

"Hooowwllll!" Blade howled, lunging with claws that sliced the air like fucking razors, speed insane for his bulk, the sanctuary's ground trembling under his charge.

Aaron sidestepped, dodging the claws, but Blade pulled some slick-ass shit. He pivoted mid-air, limbs hitting the ground and redirecting like a goddamn sports car, jaws snapping for Aaron's throat with precision that screamed hybrid perfection.

Aaron threw up his arms to block, but Blade's teeth chomped through, shearing off his forearm like it was paper. "Well, fuck me, those teeth are sharp as shit!" Aaron laughed, his arm regrowing in a flash, hybrid healing kicking in like a cheat code from his system.

He stuck to defense, letting Blade flex, genuinely impressed by the hybrid's speed and power. "This your best shot?" Aaron taunted, dodging another claw swipe, keeping distance to avoid Blade's crazy-ass maneuvers.

"Barely, my lord," Blade growled, shifting to a half-human form. His legs kept the werewolf's raw power, muscles thick as steel cables. His hands sprouted claws sharper than vampire or werewolf, glinting like fucking daggers. Golden eyes bled crimson, fangs jagged, nose morphing to a partial snout. He towered taller, a hybrid killing machine built to dominate.

"Well, goddamn," Aaron said, grinning like he'd just won the lottery. "I made a fucking cheat-code soldier. An army of these? I'd own this world." His mind exploded with possibilities—hundreds of hybrids, loyal as hell, tearing through enemies like they were nothing. He dove back into the spar, dodging Blade's attacks, testing the limits of his first hybrid, ready to build an empire in this unforgiving universe.
