Cold, stagnant water lapped against Leo’s boots as he pushed open the decaying iron doors. Rust flaked off under his heavy grip, falling into the black depths below. Gothic arches loomed overhead, half-swallowed by the rising tide of the apocalypse. Algae coated the ancient stone walls, smelling of salt, rot, and old copper. This place had once been a monument to human faith, a sanctuary where people sought salvation from the heavens. Now, it was just another drowned tomb, silent and forgotten by a world that had moved on. Overhead, fractured stained-glass windows cast eerie, disjointed illumination across the flooded nave. The saints depicted in the glass were cracked, their faces missing, replaced by the creeping vines of mutated moss. Nature had reclaimed what humanity built, and the system had twisted it into something far worse. Step by step, Leo waded through the knee-deep water. His movements were slow, deliberate, and entirely silent. He didn't let his boots splash, moving like a ghost through the flooded aisles where congregations once prayed. Memories of the sanctuary’s children flickered in his mind, fuel for the cold fire burning in his chest. He could still hear Toby’s laugh, still feel Lily’s small hand holding his as she asked if they would have to run again. He had promised them safety. He had promised them a home, and he would tear the world apart before he let anyone take that away. A sharp splash broke the heavy silence. Instinct took over before his conscious mind could even process the threat. Leo lunged to the side, his body moving with the supernatural speed of a hunter who had poured hundreds of stat points into agility. Three mutated aquatic predators burst from the dark water where he had stood a second ago. They were blind, their eyes covered by thick layers of pale skin, but their sensory pits hummed with electricity. Razor-sharp fins lined their backs, and their triple-jawed mouths snapped shut on empty air. Without a single word, Leo drew his combat knife. The blade, forged from deep-sea titanium he had fished up weeks ago, gleamed with a cold, blue light. He didn't feel fear. He didn't feel hesitation. He only felt the need to eliminate the obstacles in his way. His silver blade cut through the first beast’s neck with terrifying ease. The movement was a clean, arc-like sweep that severed the spine instantly. Black blood sprayed across the stone pillars, sizzling as it hit the stagnant water. Blood, thick and foul, began to cloud the pool, drawing more predators from the depths of the flooded pews. He could hear them thrashing in the dark, sensing the copper in the water. Another beast lunged from the shadows on his left, its maw open wide to swallow his torso. Leo didn't flinch. He stepped into the attack, using the monster's own momentum against it with ruthless efficiency. Snapping his wrist forward, he drove the hilt of his knife upward, shattering the creature’s jaw. In the same fluid motion, he spun and kicked the third predator, sending it crashing into a stone pillar with enough force to crack the ancient marble. It sank without a sound. Power hummed through Leo's veins, a brutal outcome of his growth. He was no longer the naive boy who hesitated to take a life, even a monstrous one. The world had stripped that luxury away from him, replacing his soft edges with cold, hard steel. These creatures were merely obstacles in his path. They were nothing compared to the monsters wearing human skin who threatened his home. If the Sovereign Coalition wanted to burn his sanctuary, he would become the monster they feared. Wiping the black ichor from his cheek, Leo didn't even look back at the floating carcasses. His eyes remained fixed on the far end of the cathedral, where the water began to change color. --- Floating wooden pews drifted like coffin lids in the deeper water of the transept. Leo pushed past them, his gaze scanning the shadows of the collapsed balconies above. High up in the shadows, dozens of glowing red eyes blinked in unison. Mutated cave bats, their wingspan spanning over six feet, clung to the vaulted ceilings. They hissed, their fangs dripping with paralytic venom, sensing the intruder below. Instead of waiting for them to strike, Leo tapped his foot against the submerged floor. A shockwave of pure force rippled through the water, shattering the surface and sending a deafening vibration through the air. Startled by the sudden sonic blast, the bats screeched and scattered, fleeing deeper into the dark recesses of the cathedral. He didn't waste time hunting them down. Speed was his only ally now. Every second he spent in these ruins was a second closer to Lord Arthur's deadline. The Sovereign Coalition’s threat was not an empty one. He had seen the charred ruins of other settlements that refused to bow to their feudal rule. Ruthless warlords ran the Coalition, men who viewed survivors as nothing more than livestock and labor. They wanted his cosmic fishing rod because they knew it could break the system's balance. They wanted his head because he offered humanity a choice. He would rather die than hand over his people to those monsters. Deep water now reached his chest as he approached the inner sanctum. The air grew warm, thick with a heavy, sweet scent that smelled of ozone and blooming lilies. It was a beautiful smell, but in this ruined world, beauty was almost always a warning sign. Emerald light pulsed from beneath the surface of the high altar, casting long, wavering beams up toward the vaulted ceiling. The light was hypnotic, swirling with tiny, glowing particles of pure cosmic mana. Rising from the center of the flooded ruins was the high altar. It was a massive slab of white marble, miraculously untouched by the moss and decay that ruined the rest of the cathedral. It stood like a monument of pure light in a world of darkness. Water of absolute purity pooled around the altar, forming a perfect, circular basin. It hummed with a low, vibrating cosmic energy that resonated in Leo’s chest, pulling at his very soul. This was the neutralizing spring. The energy radiating from the pool was dense enough to make his skin tingle, a rich concentration of pure, unadulterated system power. It was exactly what he needed to save his people. Standing on the edge of the marble steps, Leo looked down into the glowing green water. It was incredibly deep, stretching down into a bottomless abyss of pure light. He could feel the sheer potential of the spring, a resource that could easily shield his sanctuary from any threat. Golden runes suddenly flared in his vision, his passive skill activating with an aggressive, warning chime. Ruler's Insight pulsed violently behind his eyelids, the system interface flashing in bright, blood-red text. "System Warning: The detected water source is not a natural phenomenon. It is an artificial construct. A trap designed by an ancient system entity to snare high-level harvesters. Extracting resources from this pool will trigger an irreversible lockdown." Leo stared at the warning, his breath hitching in his throat. His fingers tightened around the handle of his cosmic fishing rod, the metal cold against his palm. Desperation clawed at his chest, hot and suffocating. He didn't have time to search another ruin, nor did he have the luxury of finding another source of power. The Sovereign Coalition’s bombers could already be preparing for takeoff. If he hesitated, the sanctuary would burn. The children—little Lily, Toby, all of them—would be turned to ash while he stood here playing it safe. He couldn't let them down. Whispers of their laughter echoed in his memory, a sharp contrast to the cold, dead stone of this tomb. He had promised them they would be safe. He had promised himself he would never lose another family. Lifting the heavy, silver-wrapped grip of his cosmic fishing rod, Leo braced his feet against the wet marble. His knuckles turned white, his jaw clenching so hard his teeth ached. With a sharp flick of his wrist, he cast the line. The cosmic hook sliced through the air, leaving a trail of starlight behind it as it flew toward the center of the pool. Air whistled as the line unspooled, a clean, silver thread cutting through the emerald glow. Splash. The hook broke the surface of the glowing green pool, sinking rapidly into the emerald depths, drawing the cosmic line deep into the heart of the light. Instantly, the humming sound stopped. The warm, sweet air turned freezing cold in a heartbeat, his breath pluming in white clouds before him. Jade stone, vibrant and impenetrable, began to spread from the point of entry. The water solidified in a violent flash of green light, transforming from liquid to solid stone in less than a second. Panic seized Leo as the solid stone raced up the line. He tried to yank the rod back, his muscles bulging under his coat, but it was already too late. Ignoring the warning out of sheer desperation for his children, Leo casts his line, only for the water to suddenly solidify into solid jade, trapping his cosmic rod deep within the stone.
