99% CASUALTY RATE: I GAMBLE MY LIFESPAN TO SURVIVE

The Weight of the Gamble

The Ironclad Vanguard took its first step forward. The sound of its heavy, rusted iron boots hitting the cobblestones echoed through the vaulted chamber like a strike against an anvil. The massive eight-foot giant swung its double-edged claymore outward, the heavy blade cutting through the pale mist with a sharp, terrifying hiss.

Beside Marcus, Luke froze completely, his breathing catching in his throat as the heavy mechanical pressure in the room bore down on them. Through his Void Perception, Marcus could see the monster’s energy blueprint. The Vanguard wasn't hollow; its armored shell was overflowing with a dense, swirling vortex of dark purple power. Its primary core pulsed violently right behind the center of its rusted breastplate, heavily protected by inches of enchanted iron.

Ping.

The crimson system interface expanded rapidly across Marcus's field of vision, the letters blinking with an urgent, demanding light.

Ten years.

Marcus felt a cold sweat break out across his forehead. He had already traded six years of his life just to clear out the basement corridors and survive the initial hounds. Giving up another decade would drop his remaining lifespan down to thirty-nine years. He would be physically sacrificing the prime of his life before he even reached his thirtieth birthday. He could already feel the phantom toll of his previous trades whispering in his joints, a subtle, deep ache that hadn't fully gone away.

The giant Vanguard accelerated, its massive armored form moving with an unnatural, terrifying speed that completely defied its heavy weight. It covered half the distance of the chamber in two massive bounds, lifting the claymore high above its helmet as it targeted their stone outcrop.

If he didn't take the trade, his survival probability was eight percent. He would die in the next three seconds, leaving him with zero years anyway.

The math was brutal, simple, and absolute.

'Accept,' Marcus commanded in his mind, his resolve locking into place like a steel vice.

A violent, catastrophic spasm of agony ripped through Marcus's entire torso. It felt as though a massive, invisible hand had reached deep inside his chest and physically torn away a massive chunk of his life force. His vision went completely white for a fraction of a second, his skin turning a sickly, hollow pale as a wave of immense exhaustion threatened to drop him to his knees. His lungs burned, gasping for air that felt suddenly thin.

But right behind the agony came the power.

[Transaction Complete. Remaining Lifespan: 39 Years, 212 Days.]

[Permanent Active Skill Unlocked: Sovereign’s Execution.]

"Luke, move right!" Marcus roared, his voice raspy and strained from the sudden physical toll.

Using the absolute limit of his Overclocked Vigor, Marcus threw himself backward just as the Vanguard’s massive claymore came crashing down. The heavy blade struck the stone outcrop, shattering the solid rock into a violent explosion of flying shrapnel and dust. The force of the impact sent a shockwave through the cobblestones, knocking Luke flat onto his back a few feet away.

Marcus landed on his feet, his heart slamming violently against his ribs. Through the swirling dust cloud, his Void Perception tracked the giant. The Vanguard was recovering from its massive swing, its claymore temporarily embedded an inch deep into the cracked floor. The heavy iron breastplate was perfectly exposed.

Now.

Marcus sprinted forward, his boots skidding across the debris. He channeled every single ounce of the black, crackling electricity inside his veins into the wooden handle of his fire axe. The weapon grew incredibly heavy, the aura expanding until it resembled a jagged crescent of pure, localized darkness.

"Sovereign’s Execution!" Marcus roared.

The Vanguard snapped its helmet toward him, the horizontal slit of crimson light flashing with sudden awareness. It tried to rip its claymore free to block, but it was a fraction of a second too late.

Marcus leaped into the air, his muscles screaming under the intense, crushing strain of the skill. He swung the fire axe downward with everything he had left in his body.

The black crescent blade struck the center of the rusted iron breastplate. The heavy armor didn't just dent; the system skill caused the steel edge to pass directly through the solid iron plate as if it were nothing but thin air. The axe buried itself deep into the monster’s chest, biting straight into the pulsing purple core.

CRACK.

A blinding explosion of dark energy erupted from the fracture point, throwing Marcus backward across the chamber floor. He slid several feet, tumbling hard over the ancient cobblestones before finally coming to a halt. The fire axe flew from his grip, clattering into the darkness.

Marcus lay flat on his back, staring up at the vaulted ceiling. He couldn't move his arms. His muscles felt completely torn, and a deep, terrifying emptiness echoed in his soul—the permanent scar of the ten years he had just thrown into the market. He felt weak, older, and thoroughly battered.

Across the room, the Ironclad Vanguard froze. The horizontal crimson light in its helmet flickered rapidly, then went completely dark. Hairline fractures of bright blue light spread across its rusted armor, spiderwebbing outward until the massive eight-foot giant shattered into a massive cloud of glittering, dark ash.

A heavy, echoing thud vibrated through the stone floor as a massive, glowing blue crystal—the size of a human fist—dropped into the pile of remnants.

The blue galaxy of the transition rift above them began to pulse violently, its locking mechanisms dissolving into thin air.

[Regional Field Boss Defeated. Evaluation: Flawless Critical Strike.]

[Rewards Distributed: High-Grade Vanguard Core x1.]

[Path to First Floor: Unlocked.]

Marcus let out a slow, ragged breath, his eyes staring at the glowing blue portal. He had survived the basement, but the cost was carved into his very lifespan. He was running out of time, and the real tower hadn't even begun.
