99% CASUALTY RATE: I GAMBLE MY LIFESPAN TO SURVIVE

The Currency of Time

The silence that followed the boss’s demise was heavy and absolute. Marcus lay on the uneven cobblestones for a full minute, his chest heaving as he stared blankly up at the vaulted ceiling. The blinding blue light of the unlocked transition rift swirled lazily above him, casting long, rhythmic ripples of sapphire illumination across the ancient chamber.

Every single nerve ending in Marcus's body felt like it was on fire. The physical exhaustion was immense, but it was the internal emptiness that truly terrified his rational mind. His lungs labored to pull in air, and a deep, permanent ache had settled right behind his breastbone. Thirty-nine years. That was all he had left in his biological ledger. He was twenty-eight, but his soul felt heavily anchored by the invisible theft of sixteen years.

"Marcus... Marcus, man, please tell me you're alive," Luke’s voice cracked through the quiet space.

Marcus heard the frantic scraping of boots against stone as Luke ran over. The younger man knelt beside him, his hands hovering over Marcus's blood-splattered uniform, completely unsure of what to do. Luke’s face was smeared with dark soot, his eyes wide with a frantic mixture of horror and profound relief.

"I’m alive," Marcus rasped out, his voice sounding significantly rougher and deeper than it had an hour ago. He forced his stiff, aching fingers to ball into a tight fist, fighting through the wave of phantom fatigue. "Help me up."

Luke grabbed Marcus’s arm, grunting as he hauled the older guard to his feet. Marcus stumbled slightly, leaning his weight heavily against a jagged shard of the broken stone outcrop until his balance finally stabilized. He wiped a streak of cold sweat from his forehead and looked down at his right hand. His skin looked subtly less vibrant, the faint lines around his knuckles slightly more pronounced. The transaction was real. The system did not give discounts.

"Look at the board," Luke whispered, his eyes fixed on the floating blue glass interface that remained suspended in the middle of the room. "Look what you did."

Marcus shifted his cold gaze to the leaderboard. The lines of text hummed with fresh updates.

Rank 1: Marcus Gray (Level 4) — Floor Progress: Basement Transition

Rank 2: Victor Kane (Level 3) — Floor Progress: 3rd Floor

Rank 3: Eleanor Cross (Level 2) — Floor Progress: 4th Floor

Rank ... Total Active Survivors: 34/350.

He had bypassed Victor Kane to claim the top spot in the regional sector. The massive experience influx from delivering a flawless critical strike to a Level 5 regional boss had pushed his status up by two full levels in a single moment. But as Marcus stared at his name at the absolute peak of the list, his expression didn't change. Being number one didn't matter if the total survivor count kept dropping. Seven more people had died on the upper floors while he was fighting the Vanguard.

"We need to collect the drop," Marcus said, his voice entirely flat as he pushed away from the stone support.

He walked slowly over to the massive pile of dark, glittering ash where the Ironclad Vanguard had stood. Resting right in the center of the debris was the fist-sized high-grade core. It pulsed with an incredibly dense, deep sapphire light, looking less like a crystal and more like a captured piece of a stormy night sky.

Marcus knelt and picked it up. The moment his fingers made contact with the cold surface, a sharp notification flashed across his vision.

[High-Grade Vanguard Core Detected.]

[Value: 500 System Credits OR 2 Years of Regenerative Lifespan.]

[Would you like to convert this item to lifespring resources?]

Marcus’s breath hitched in his throat. Buy back time. The system wasn't just a one-way street of sacrifice; it was a literal market. If he could harvest high-grade cores from boss monsters, he could systematically rebuild his stolen years. The discovery instantly validated his entire strategy. He didn't just need to survive; he needed to hunt the biggest threats available if he wanted to live to see old age.

"Marcus? What is it?" Luke asked, noticing the sudden intensity in Marcus's gaze.

Marcus stood up, slipping the heavy sapphire core securely into his tactical vest pocket. He chose not to convert it immediately. Two years of life was tempting, but entering the first floor with five hundred credits might buy him a weapon or a skill that would save him from sacrificing ten years down the line. He had to think like an investor.

"It's currency," Marcus said simply. He walked over to the dark corner of the room, retrieved his standard fire axe, and checked the handle. The wood was slightly charred, but the steel blade was entirely intact, still humming faintly with the remnant traces of his permanent skills.

He turned toward the swirling blue vortex of the transition rift. The portal hummed softly, drawing in the pale mist of the chamber like a vacuum.

"We're going up," Marcus stated, adjusting his grip on the axe. "The first floor is going to be completely different from the basement. The survivors up there are already organizing under Victor and Eleanor. If we want to maintain the advantage, we hit the ground moving."

Luke looked at the glowing blue portal, swallowing hard. The absolute terror was still present in his eyes, but a new, quiet layer of resolve had finally begun to form underneath. He picked up his dropped flashlight, gripped it like a weapon, and stepped up right beside Marcus.

"Right behind you, boss," Luke said.

Marcus didn't waste another second. He stepped directly into the brilliant sapphire light of the rift, his body instantly dissolving into the vortex as the system prepared to transition him to the first floor.
