The Last Catalyst

The 99th Extinction

The sky above Montana City wasn’t blue anymore. It hadn't been for a long time, but today, it was the color of fresh, arterial blood. Harrison spat a mouthful of metallic tasting grime onto the shattered concrete of Sector 0. His left arm hung uselessly at his side, the nerve endings completely severed by the kinetic back blast of an exploding defense turret.

 

Around him, the pinnacle of human achievement lay in ruins. Titanic steel monoliths that once housed millions were sheared in half, weeping sparks into the suffocating layer of ash that blanketed the battlefield. "Hold the line!" a voice screamed over the localized comms network, high-pitched, frantic, and entirely hopeless. "The Vanguard is down! Where is the aether support?!" Harrison didn't bother looking for the support. He already knew they were dead.

As a veteran tactical analyst, his job was to know the exact numbers, the precise distributions of force, and the brutal mathematics of survival. Right now, the math equated to absolute zero. A low, vibrating hum resonated through the earth, so deep it threatened to shake the teeth loose from Harrison’s jaw.

 

The ash on the ground danced, vibrating in perfect, terrifying rhythm. From the dense shroud of smoke, It emerged. It didn't look like a beast born of flesh and blood. It was a localized catastrophe wrapped in a crystalline, obsidian carapace.

The World Boss the entity the system simply designated as The End. Its shifting, multi-jointed form towered over the remains of the sector wall, a walking singularity that absorbed the ambient light around it. Every time its massive, blade-like limbs struck the ground, a localized shockwave rippled outward, dissolving solid concrete into fine powder.

 

A squad of surviving A-Rank hunters the elite protectors of Montana City launched a desperate counterattack. Brilliant arcs of lightning and dense barriers of compressed aether illuminated the crimson sky. They moved with flawless synchronization, the apex of human combat potential. To Harrison, watching through his dirt-caked tactical visor, it looked like children throwing pebbles at a moving mountain.

 

The End didn't even pause. A single, blinding flash of dark energy erupted from its central core. The A-Rank hunters didn't have time to scream. Their aether barriers shattered like cheap glass, and their bodies were reduced to gray dust before they even hit the ground.

 

A generic, blue translucent screen flickered weakly in the corner of Harrison's vision, flashing a weak combat power drop warning. Sector 0's defense capability was down to almost nothing. It was the standard Basic System Interface that every human awakened at age eighteen cold, unfeeling, and utterly useless in the face of true despair.

For ten years, Harrison had relied on this basic system, using his mind instead of raw power to guide humanity through ninety-nine separate timelines. Yes, ninety-nine. Every time the world ended, Harrison had been violently reeled back to the beginning, a cosmic joke forced to watch the apocalypse play out in a loop. He had tried everything. In one life, he had trained as a frontline warrior, only to be crushed in Sector 4.

 

In another, he had played the politician, uniting the factions early, only for a hidden betrayal to tear the walls down from the inside. He had been a scholar, a rogue, a commander. And now, in his ninety-ninth life, as a tactical analyst, he had come the closest.

They had reached Sector 0. They had faced the final threat. And they had still been utterly erased. "Is this it?" Harrison whispered, his voice cracking as he collapsed against the ruins of a reinforced bulkhead, his lungs burning with every breath of toxic air. "Ninety-nine times. I’ve given everything. Every strategy, every variable... there is no winning configuration."

The massive, glowing eyes of The End turned toward his direction. The entity didn't see a threat; it saw trash waiting to be swept away. A localized distortion of gravity formed around Harrison, pinning him to the rubble. The pressure was immense, cracking his ribs one by one. Harrison stared back at the god-like entity. He didn't feel fear anymore. He just felt an all consuming, freezing exhaustion.

 

The standard blue notification screen began to glitch violently, tearing apart into jagged lines of green and gold code that Harrison had never seen in any of his past ninety-nine lives. The End raised a colossal, obsidian blade to deliver the final strike. "Do it," Harrison snarled, coughing up dark blood. "Send me back. Let's see if I care on the hundredth time." The blade descended, cutting through the air with a deafening sonic boom.

 

The world turned entirely black. System overhaul complete. Core protocol 'The Last Catalyst' integrated successfully. Commencing the hundredth loop, the final attempt. No further regressions permitted. This is the absolute end of the sequence. Harrison’s chest heaved violently as his lungs expanded, drawing in a massive, chaotic gulp of air.

 

The air didn't taste like ash, sulfur, or burnt copper. It tasted like hot asphalt, cheap fried food, and car exhaust. He threw himself forward off the hard wooden surface he had been lying on, tumbling onto his hands and knees. He was trembling violently, his heart hammering against his ribs like a trapped bird. Instinctively, his right hand flew to his left shoulder, gripping it tightly. It was there. Whole. Unbroken. Harrison stared at his hands. They weren't covered in the calluses of a hardened veteran or stained with the blood of fallen comrades. They were smooth, slightly pale, and belonged to an eighteen year old kid who hadn't yet seen a single day of real combat. "No way..." Harrison breathed, his voice higher than he remembered.

 

He slowly pushed himself up to a standing position, his joints popping as he looked around to process the sensory overload. The sky above was a brilliant, unblemished blue, clear of any ash or smoke. He was standing in a bustling, open-air plaza. Towering digital billboards flashed advertisements for modern aether-tech cosmetics and local hunter guilds.

 

Crowds of people walked past him, laughing, talking on their devices, and carrying shopping bags. They were completely oblivious to the horrors of the front lines. They were alive. Harrison turned around and looked at the large glass structure behind him. Above the sliding doors, bold metallic lettering read: SECTOR 4 CENTRAL MALL. A bitter, hysterical laugh escaped his throat. He knew this place. He knew this exact day.

 

It was the afternoon of his eighteenth birthday the day he had originally awakened his basic, useless analyst path and decided to dedicate his life to strategy. But something was fundamentally different this time. The air felt heavier, vibrating with a strange, latent energy that seemed to focus directly behind his eyes. The gold text that had appeared during his death wasn't a hallucination. Harrison closed his eyes, took a deep breath, and thought the command that had become second nature over a century of living.

 

*System, open.*

 

Instead of the familiar, generic blue screen that every citizen of Montana City possessed, a shockwave of golden light seemed to ripple outward across his vision. The sheer clarity of the interface made his previous system look like an archaic piece of scrap metal. A pristine, sharp holographic display locked onto his retinas, presenting the Regressor Log.

He was at F-Rank, Tier 1, with raw attributes of twelve strength, fourteen agility, and eleven vitality. But his gaze locked entirely onto his innate talent. The Casualty Counter. An EX-Rank locked progression talent that allowed him to perceive the exact time, cause, and probability of death for any localized entity.

 

"Rank EX..." he whispered, his eyes widening. In all his ninety-nine lives, through all the thousands of hunters, commanders, and prodigies he had analyzed, he had never encountered an EX-Rank talent. The highest known tier in human history was S-Rank, held only by the supreme leaders of the central sectors.

 

An EX-Rank talent was a statistical anomaly a breaking of the world's established rules. And more importantly, the safety net was gone. If he died in this loop, there would be no hundred-and-first regression. There would be no restarting. This was the absolute end of the line. "Fine," Harrison muttered, a cold, dangerous fire igniting deep within his chest. He wiped a bead of sweat from his forehead, his posture instantly shifting from a panicked teenager to a seasoned survivor. "No more safety nets. Let's see what this talent can actually do." He lifted his head and looked out into the bustling crowd of the Sector 4 mall plaza.

 

The moment his focus shifted to the people around him, the golden system interface reacted. The world didn't change, but a translucent layer of ominous, crimson data began to overlay reality. Floating above the head of a businessman talking on a phone, the system projected a lifetime of forty-two years before dying of natural causes. Above a young mother pushing a stroller, a floating notification warning of thirty-one years remaining before a Sector 2 outbreak.

Harrison exhaled a breath he didn't realize he was holding. The system was showing him the literal expiration dates of every living soul within his field of vision.

 

It was a dizzying, god like perspective, a map of mortality unfolding in real time. But as Harrison’s gaze swept across the courtyard toward the outdoor seating of a nearby café, the crimson text above one particular individual began to flash violently, turning a blinding, toxic shade of scarlet. Sitting at a table, reviewing data on a sleek hand-held tablet, was a young woman.

 

She had sharp, elegant features, and long dark hair tied back in a practical, military-style braid. Even while sitting down, her posture was perfectly straight, radiating the disciplined aura of someone born into a high-tier military family. Harrison recognized her instantly. Aella Vance. In his ninety fifth and ninety seventh lives, she had been the undisputed commander of the Sector 4 Vanguard an absolute monster of an A-Rank Catalyst who could manipulate spatial energy to tear entire legions of beasts apart. She had been one of humanity’s strongest shields. But right now, she was just an eighteen year old academy applicant, completely unaware of the countdown glowing like a neon death sentence directly above her head. Harrison focused entirely on her screen, and the Casualty Counter expanded, forcing a brutal, flashing warning into his mind. Target: Aella Vance. Time till death: fourteen minutes and ticking.

 

Cause of mortality: ruptured vitals via a Tier-1 Supernatural Beast, a Shadow Stalker, during the Sector 4 Mall Incursion. Her inherent potential was listed as high A-Rank. The system prompted him to alter this timeline to unlock Fate Points and extract a portion of her latent power, warning that failure to do so would result in her permanent expiration.

 

Harrison's eyes locked onto the numbers. Fourteen minutes. In exactly fourteen minutes, a supernatural beast incursion was going to strike the very ground they were standing on, and one of humanity's future greatest protectors was going to die before her story even began. Harrison looked down at his own weak, F-Rank attributes. His strength was a pitiful twelve.

 

He didn't have any combat skills, no weapons, and no armor. If a Shadow Stalker caught him in the open, he would be torn to pieces in seconds. But he had something far more valuable than raw stats. He had a hundred lifetimes of tactical data, absolute knowledge of beast behavior, and a system that allowed him to see the exact threads of fate.

"Fourteen minutes," Harrison said, a sharp, cold smile cutting across his face as he stepped into the crowd, moving directly toward Aella’s table. "Let's change the future."
