Vibrations rattled the rusted metal plates of the sanctuary floor.
Dust drifted down from the cracked concrete ceiling of the old warehouse, coating everything in a fine grey powder that tasted like dry copper.
Deep beneath the earth, something massive was shifting, its movements slow and deliberate.
Leo pressed his palm flat against the cold concrete floor, feeling the rhythmic, violent thudding that signaled approaching doom.
His heart hammered against his ribs, a frantic counterpoint to the terrifying rhythm below.
This wasn't a normal tremor; it was too focused, too targeted, rising up from the dark depths directly beneath them.
Maya's voice trembled as she clutched Toby close to her chest.
Her knuckles were stark white, her eyes wide with a raw terror she couldn't hide.
Around her, a dozen other orphans huddled together, their small bodies shaking in unison as they looked to Leo for reassurance.
They had survived so much, yet the earth itself was turning against them.
Cracks spiderwebbed across the concrete, spreading outward from the center of the main hall like frozen lightning.
A terrible, grinding sound echoed from the dark depths, shaking the wooden support beams overhead.
System alerts began to flash in the periphery of Leo's vision, bathing his retinas in an ominous crimson light.
[WARNING: Three Colossal Gravel-Worms (Level 35) have detected high-density life signatures.]
[Estimated time until breach: 45 minutes.]
[Sanctuary structural integrity: 64% and falling.]
Cold sweat beaded on Leo's forehead, dripping down his temple as his pulse raced.
His jaw clenched so hard his teeth ached, a sharp pain radiating up to his ears.
Level thirty-five monsters were far beyond anything they had faced so far, and three of them at once would turn this sanctuary into a mass grave in seconds.
Memories of his lost orphan family flashed before his eyes—the screams of the children, the collapsing walls of their previous shelter, the feeling of absolute helplessness as the first dungeon break took everyone he loved.
He had sworn never to let that happen again.
Protecting these children was his sole purpose, no matter the cost.
Desperation clawed at his chest as Leo rushed toward the small, glowing pond he had established at the back of the warehouse.
This was his lifeline, his only hope against the horrors of the ruined world.
His cosmic fishing rod materialized in his hands with a soft, resonant hum of power, its silver frame etched with faint purple constellations that pulsed with ancient energy.
Flicking his wrist, he sent the glowing line flying into the dark water.
Splash went the bobber, sending concentric ripples across the surface of the pool.
He waited, his entire body tense, his muscles coiled like springs, praying for a miracle that would save them.
"Come on, please," Leo whispered, his voice cracking with the weight of a dozen lives resting on his shoulders.
"Give me something big. A strength multiplier, an earth-binding skill, anything to stop them from tearing this place apart."
A sharp tug vibrated through the line, nearly pulling the rod from his grip.
He reeled it in with frantic speed, his muscles straining as he hauled the catch out of the water.
A bright blue light flared, revealing his prize, but his heart sank as he read the system notification.
[Successful Catch: Common Agility Essence (+1 Agility)]
Useless, completely useless in this situation.
A single attribute point wouldn't stop a forty-foot worm from swallowing them whole.
He threw the essence aside and cast the line again, his movements frantic, bordering on manic as the ground shook violently beneath his feet.
Releasing a jagged breath, he watched the bobber sink almost instantly.
He pulled, feeling barely any resistance this time.
Water splashed, and another screen popped up, mocking his desperation.
[Successful Catch: Minor Health Elixir (Heals 20 HP)]
Frustration boiled in his veins.
He threw his rod down, the heavy wooden floorboards creaking under his boots.
Water in this sanctuary was too low-tier, its spiritual essence completely depleted by his continuous harvesting of basic attributes over the past weeks.
It could no longer provide the high-grade power he desperately needed.
To pull up high-tier attributes or powerful crowd-control skills capable of halting level thirty-five beasts, he needed a deeper, more volatile source of energy.
He needed a body of water that had been exposed to the raw, unfiltered mana of the apocalypse, untouched by human hands.
Scouts had warned him of a place on the edge of the city—an abandoned water treatment plant housing the Abyssal Reservoir.
It was a high-tier danger zone, crawling with elite predators, but its waters were saturated with concentrated cosmic mana from the ruptured dungeon network.
"I have to leave," Leo said, turning to face the children.
Words felt like lead on his tongue, dragging his spirit down into the dirt as he looked at their pale, terrified faces.
"No!" Maya cried, stepping forward and grabbing the hem of his worn jacket, her small fingers trembling.
"You can't go. The ground is shaking. If those things come up while you're gone, we won't survive. We need you here."
Kneeling in front of her, Leo grabbed her shoulders, his grip firm but gentle.
He hated himself for the lie he was about to tell, but he had to keep them calm.
"I will be back before they break through. I promise you, Maya. I won't let anything happen to you."
Guilt gnawed at his stomach like acid.
He didn't know if he could make it back in time, let alone survive the reservoir.
If he failed, these children would be buried alive in the dark, and their blood would be on his hands forever.
Standing up, Leo turned to the massive, iron-hard vines that lined the walls of the sanctuary.
These magical plants were his creation, grown from rare seeds he had fished up earlier, and they were the only defense he could leave behind to protect them.
Concentrating his remaining mana, he commanded the vines to move.
Thick, thorny stalks began to crawl across the ceiling, weaving together to form a dense, protective dome over the children, sealing them away from the falling debris and the trembling earth.
"Shield them," Leo muttered, his voice thick with emotion as he poured the last of his energy into the plant's core.
"Do not let anything through until I return, no matter what happens."
Vines snapped into place with a heavy, metallic thud, sealing the kids inside a green fortress of living wood.
He could still hear Maya's muffled cries through the thick foliage, a sound that threatened to break his resolve completely, but he forced himself to turn away.
Wiping a stray tear from his cheek, Leo grabbed his cosmic rod, strapped his hunting knife to his belt, and sprinted toward the exit of the warehouse, leaving his heart behind.
---
Outside, the ruined city was a graveyard of concrete and rusted steel.
Cold wind whipped through his hair, carrying the metallic scent of decay and distant ozone.
A bruised purple sky hung heavy with the threat of rain, matching the darkness in his mind.
Every step away from the sanctuary felt like a physical weight pressing down on his chest.
His lungs burned, screaming for air as he pushed his body to its absolute limits, leaping over piles of rubble and abandoned cars that littered the empty streets.
Shattered skyscrapers loomed over him like giant tombstones, their glass windows long gone.
He navigated the cracked asphalt, his boots pounding a frantic rhythm against the ground as he avoided the dark alleyways where low-level beasts growled in the shadows, waiting for an easy meal.
Time was ticking away.
Every second he spent running was a second closer to the worms breaching the warehouse floor.
He checked his system map, his eyes locked on the blinking blue dot that marked his destination, praying he wasn't running toward his own doom.
Looking down at the industrial sector ahead, he saw the massive chain-link fence of the water treatment plant appearing through the thick fog.
Rusted metal fence posts were corroded, twisted outward as if something massive had forced its way out of the facility years ago during the collapse.
Vast, thorny briars choked the streets surrounding the plant, their black needles glistening with a sticky, toxic sap that could paralyze a grown man in seconds.
Leo bypassed them, using his agility to leap from the roof of a rusted bus to a crumbling concrete wall, barely clearing the hazards.
Footsteps echoed in the distance, but he didn't dare look back to see what was hunting him.
Whether it was a predator or one of the Sovereign Coalition's scouts, he couldn't afford to stop and fight, not when every second counted.
Quietness hung over the area, a heavy, unnatural silence that made the hairs on the back of his neck stand up.
Normal ambient sounds of the city's monster-filled ruins were entirely absent here, replaced by a suffocating void that felt almost predatory.
Pushing past the broken gate, Leo made his way toward the main reservoir building.
Concrete domes rose like ancient temples, their walls stained with dark algae and bullet holes from the early days of the collapse when humanity tried and failed to defend the facility.
Slipping through the gap of the heavy steel doors, he was immediately hit by a wave of freezing, stagnant air.
Freezing air bit at his exposed skin, turning his breath into thick white plumes that hovered in the dark room.
Darkness swallowed him as he stepped deeper into the facility, his boots clicking softly against the frost-covered concrete.
He gripped his fishing rod tightly, the cold metal of the handle freezing against his palm as he navigated the maze of rusty pipes.
As Leo arrives at the edge of the pitch-black water treatment plant, he finds the reservoir covered in a layer of frozen, glowing blue ice that is humming with a melody that sounds like a human whisper.
