The heavy iron door slammed shut with a deafening CLANG, its ancient deadbolts grinding into the stone frame with the finality of a coffin lid.
Instantly, the world changed. The chaotic, mind-shattering roar of the underground river was muffled into a dull, distant thrum. For Lenus, the "acoustic snowblindness" vanished. His mental canvas cleared, leaving behind only the sharp, geometric wireframes of the room they had just entered.
No more jagged caves. No more sweeping, organic tunnels.
Everything here was built with terrifying, soulless precision. Perfect right angles. Parallel rows of heavy oak weapon racks. Iron pillars spaced exactly ten feet apart. The ambient air was dry, smelling heavily of forge ash, old gun-oil, and polished steel. It was the smell of a machine waiting to be turned on.
Lenus took one step away from the door and his knees simply gave way.
[HP: 28/140]
[Condition: Hypothermia (Severe) - Motor functions failing.]
He hit the floor hard, his katana clattering against the stone. His body was convulsing so violently he couldn't form words. The freezing water of the aqueduct had seeped into his very marrow, and the LitRPG system wasn't just numbers—it was a physiological reality. His heart was struggling to beat through the ice in his veins.
"Inias!" Elara dropped her massive Claymore and slid to her knees beside him. She was shivering intensely, her lips a bruised blue, but her golden aura flared with a stubborn, radiant heat. She hauled him up, draping his mangled left arm over her cold steel breastplate.
"Shrine," Lenus forced out through chattering teeth, his voice a broken, frozen hiss. "Find... the basin."
"I don't see one!" she said, her voice echoing slightly in the vast, perfectly square hall. "It's just weapon racks and shadows. There's no light, Inias!"
Listen, Lenus commanded himself, fighting through the dark fog clouding his brain. Filter out the shivering. Filter out the grinding of her armor. He closed his eyes beneath his scarred lids, expanding his [Aura Perception] and his hearing. The armory was massive, but it wasn't empty.
Through the thick stone walls to their left, he heard the crisp, terrifyingly synchronized sound of marching. Snap-step. Pause. Snap-step. It wasn't the dragging, heavy lumber of the Hollowed Guards in the Necropolis. This was a tactical patrol. They were moving in a phalanx, their boots striking the floor with unified, military precision.
And then, he heard it. A sharp, rhythmic clicking sound.
Click-clack. Click-clack.
"Crossbows," Lenus wheezed, the realization sending a spike of dread through him. "They're... winding arbalests. Corrupted Sentinels."
In the game, the Lower Bastion was a nightmare for melee builds. The Sentinels held choke points, firing heavy bolts that could pin a player to the wall, while spearmen formed an impenetrable wall of iron. They didn't just aggro and charge; they formed defensive lines and executed crossfire.
"We can't fight them like this," Elara whispered, hearing the distant, rhythmic march. She hoisted him tighter against her side. "Which way?"
Lenus tapped his foot weakly against the floor. A faint silver wave rippled out, dying almost instantly. But through the rows of weapon racks, about thirty yards to their right, the sound caught on a distinct, circular stone object resting in the center of an alcove. A faint, hollow draft curled around it.
"Right," Lenus gasped. "Thirty paces. Through the racks."
Elara didn't question him. She grabbed the leather-wrapped hilt of her Claymore with her free hand, dragging it silently across the floor as she supported Lenus's dead weight. They moved through the aisles like ghosts. To Lenus, it felt like walking through a forest of iron. Halberds, maces, and broadswords hung suspended in his acoustic map, humming with a faint, residual lethality.
"Stop," Lenus suddenly breathed.
Elara froze. From the corridor directly ahead of them, a heavy iron portcullis began to grind upward with a screech of rusted gears. The patrol was entering the armory.
Snap-step. Pause. Snap-step.
Six auras bled into Lenus's perception. They glowed with a sick, bruised-purple light—the signature of the corrupted Vanguard elite.
"They're sweeping the room," Elara whispered, her breath frosting in the cold air. She pressed Lenus against the side of a massive oak weapon rack, hiding them in the deep shadows.
Lenus's HP ticked down. [HP: 20/140]
He was going to freeze to death before the patrol even found them.
"Elara," Lenus breathed, his hand trembling as he reached into his pocket. He pulled out the cold, metallic core he had ripped from the Hollowed Guard. "The basin... is ten feet behind you. Take this."
She looked down at the core, then at his pale, scarred face. "If I leave you here to light it, they'll hear me. They'll shoot you where you sit."
"If we don't light it... we freeze anyway." Lenus pressed the core into her gauntlet. "When I distract them... run."
Before she could argue, Lenus forced his right hand to grip the hilt of his katana. He couldn't stand, but he didn't need to. He waited for the snap-step cadence of the patrol to reach the center of the hall. He visualized their purple auras: two heavy shields in front, four crossbowmen behind. A classic wedge.
Lenus drew his blade a fraction of an inch and slammed the heavy brass tsuba against the steel of a halberd resting on the rack beside him.
CLAAAANG!
The noise was like a gunshot in the silent armory. The patrol halted instantly.
"Target acquired," a voice rasped from the darkness. It wasn't a roar; it was a hollow, dead voice, speaking with chilling military flatness. "Engage."
Thwip-thwip-thwip!
Three heavy crossbow bolts tore through the darkness, shattering the wooden rack right above Lenus's head. Splinters rained down on him as the bolts embedded themselves in the stone wall behind him with the force of artillery shells.
"Go!" Lenus hissed.
Elara exploded out of cover. Her [Silent Tread] wasn't as refined as Lenus's, but her sheer speed made up for it. She sprinted the final ten feet, diving into the alcove where the Ashen Basin sat waiting.
"Flank!" the corrupted commander ordered.
Lenus lay on the floor, his vision black, his body paralyzed. He listened to the heavy, armored footsteps closing the distance. Five yards. Three yards. He heard the creak of the crossbow string being pulled taut for a point-blank execution.
Then, a massive, roaring WHOOSH of ignited air consumed the hall.
A shockwave of pure, blinding warmth blasted out of the alcove. The Ashen Shrine flared to life, its smokeless white fire painting the entire armory in brilliant, immaculate acoustic silver.
[Ashen Shrine (Lower Bastion) Re-ignited.]
[Checkpoint Saved | Hypothermia Cleansed | HP/Stamina Restored.]
Life slammed back into Lenus's body with the force of a lightning strike. The paralyzing ice in his veins evaporated, replaced by a surging, euphoric heat. His muscles unlocked instantly.
The sudden eruption of blessed light stunned the corrupted Vanguard patrol. The purple auras in Lenus's mind recoiled, hissing in pain as the holy fire burned their Miasma-sensitive eyes.
Lenus didn't waste the opening.
He vaulted off the floor, his restored Stamina fueling a flawless [Phantom Step]. He vanished from his spot, reappearing directly inside the wedge formation of the blinded Sentinels. His katana became a silver blur. He didn't aim for the heavy chest plates; he aimed for the wrists holding the crossbows.
Snick. Snick.
Two corrupted hands holding loaded arbalests hit the floor. Before the shield-bearers could turn their massive towers to crush him, a golden comet slammed into their flank.
Elara had charged out of the shrine's radius, swinging the Claymore of the First Oath in a devastating horizontal cleave. The sheer kinetic mass of the greatsword collided with the tower shields. The impact sounded like a bell tower collapsing. The heavy iron shields dented inward, the force of the blow throwing both armored Sentinels violently into the wall.
"Stand down, traitors!" Elara roared, her voice echoing with the absolute authority of a Knight-Captain.
The remaining crossbowmen scrambled backward, their purple auras flickering in panic as their programming broke against her overwhelming presence. They abandoned their weapons and fled toward the portcullis, retreating into the deeper darkness of the Bastion.
Lenus flicked his katana, shaking off the black blood, and sheathed it.
[EXP Gained: 240]
[Level Up! Inias is now Level 5. 2 Free Attribute Points available.]
He let out a long, shuddering breath, turning his face toward the radiant warmth of the shrine. "I actually thought I was dead that time," Lenus muttered, rubbing his scarred eyes.
Elara stood among the scattered crossbows, resting the tip of her massive Claymore on the stone floor. She looked at the severed hands and the crest of the Vanguard painted on the walls.
"They spoke," she whispered, horror lacing her tone. "The Hollowed in the Necropolis were mindless husks. But these... these were my men. They followed orders. They used tactics. The Miasma didn't just kill them, Inias. It conscripted them."
"The Bastion isn't a graveyard," Lenus agreed softly. "It's a forward operating base. The Miasma is mobilizing an army."
He knelt by the fire and pulled up his UI. He immediately dumped both points into Perception. He needed his acoustic map to be sharper. If the enemies here used stealth and tactics, his sonar was the only thing keeping them alive.
[Perception: 37]
[Passive Skill Enhanced: Aura Perception radius increased by 15%. Ambient noise filtering improved.]
The ringing headache subsided entirely. The acoustic feedback from the room sharpened, turning from a blurry wireframe into a crisp, high-definition 3D rendering. He could "see" the exact grooves in the stonework and the individual links of chainmail on the floor.
He reached toward the basin's fire, noticing a prompt floating above the white coals where the Tarnished Core had burned.
[Item Purified: Vanguard Soul-Shard]
[Effect: Grants a temporary holy buff. Bypasses corrupted armor with 50% greater efficiency.]
Lenus scooped the glowing, ash-like shard from the fire and walked over to Elara.
"Rub this along the edge of your Claymore," he instructed. "It's the soul of the knight you killed in the Necropolis, purified by the First Flame. It wants to help you free its brothers."
Elara's expression softened as she took the warm shard. As she ran the pumice along the massive steel edge, the dull metal suddenly ignited with a pulsing golden light. To Lenus, the sword transformed from a heavy mass of iron into a singing, radiant beacon of lethal intent.
"The commander of the Lower Bastion was Lord Inquisitor Berg," she said, her voice dropping to a dangerous, icy register. "He was the one who cast me into the Abyss. He branded me a heretic when I discovered the King's corruption."
Lenus paused, his hand resting on his katana. In the game, Inquisitor Berg was the Floor 50 Boss—a tank with explosive traps and a tower shield.
"Then we have an objective," Lenus said, a grim smile pulling at his face. The fear was gone, replaced by the familiar, cold thrill of the boss rush. "We carve our way to the command spire. And we execute the Inquisitor."
