Inside the second-floor fire access corridor of the West District Machine Tool Factory, the pungent tang of oxidized iron, condensed frost, and heavy machine oil rolled through the freezing drafts at minus six degrees Celsius.
Before the reinforced steel blast door at the corridor's far end, two mutated guard hounds, their muscular frames swollen to the size of yearling calves, lowered their forequarters in guttural, rolling snarls.
Their radiation-warped ears twitched at microscopic vibrations; crimson saliva dripped from their interlocking external fangs onto the concrete floor, hissing in faint corrosive reactions.
Blackened claws encrusted with keratinous nodules scraped against the heavy steel plate, gouging dozens of half-inch white grooves into the metal.
From behind the threshold came the rhythmic, dying wheeze of an auxiliary diesel generator—the final life-support pulse of the underground bunker.
Lynn slid through the shattered transom window like a weightless shadow, landing on the grease-stained catwalk without a whisper of sound.
"Silent neutralization, Nox. Synchronize both targets,"
Lynn directed through the mental link.
Nox detached from his arm in a blur of liquid shadow, gliding along the rusted steel ceiling girders.
Before the mutated hounds could register the shift in air pressure above their snouts, two obsidian shadow spikes condensed in mid-air, driving downward with pneumatic velocity.
The heavy bone plates fractured with muffled crunches as the spikes pierced the occipital foramen, destroying the central nervous clusters.
The two massive beasts collapsed against the blast door without a whimper, their limbs shuddering before the life force drained away completely.
Stepping over the warm carcasses, Lynn approached the heavy mechanical lock beside the blast door.
Drawing the blueprint seized from Miller from his chest rig, he cross-referenced the maintenance bypass sequence scribbled along the margin, dialing the eight-digit mechanical sequence into the frosted steel tumblers: "7-4-9-2-0-1-8-8".
With a heavy mechanical clunk of counterweighted levers, the four-inch hardened alloy deadbolts retracted.
The door swung back an inch on greased iron hinges, venting a dry gust laden with forge coal, stale blood, and the unmistakable musk of severe human dehydration.
Lynn slipped through the gap, pulling the heavy door shut until the latches engaged to seal out the freezing blizzard and wandering predators.
Descending the spiral steel staircase into Sub-level 2, his tactical flashlight cut through the damp shadows.
Inside the subterranean heavy forging workshop, two three-meter-tall mechanical pneumatic trip-hammers loomed like iron titans, flanked by firebrick-lined melting crucibles and deep quenching oil vats.
In the far corner of the sealed office, a gaunt young man lay collapsed against a four-hundred-pound cast-steel anvil.
His blistered hands gripped a heavy cross-peen forging hammer; dark, cracked lips parted in ragged wheezes.
A yellowish bandage soaked in dried pus bound his right forearm, his body locked in a critical state of septic fever and dehydration.
Lynn stepped forward, checking the youth's carotid pulse while activating Origin True Sight.
[TARGET: BARLOW SMITH, MALE, 19 YEARS OLD, MASTER BLACKSMITH APPRENTICE.]
[STATUS: SEVERE DEHYDRATION, HEMORRHAGIC ANEMIA, SHRAPNEL PERFORATION IN RIGHT FOREARM WITH ACUTE BACTERIAL SEPSIS; HP: 12/100; PROGNOSIS: TERMINAL MULTI-ORGAN FAILURE WITHIN THIRTY-FIVE MINUTES WITHOUT INTERVENTION.]
Having verified the target's identity, Lynn unslung his trauma kit and initiated battlefield stabilization.
Lynn hung two 500ml bags of 50% hypertonic saline-glucose solution, inserting an intravenous line into the median cubital vein.
The dense electrolytes and glucose stabilized the youth's fluttering pulse within minutes.
Cutting away the gangrenous dressing, Lynn irrigated the wound with povidone-iodine, extracting two jagged iron shrapnel fragments from between the ulna and radius before packing the cavity with a full packet of Glimmer Hemostatic Powder.
He administered a deep intramuscular injection of broad-spectrum antibiotics, then fed Barlow warmed electrolyte water mixed with high-calorie nutrient paste.
Under the catalytic potency of the refined medicine and modern antibiotics, Barlow's fever broke within ten minutes, a faint flush returning to his sunken cheeks.
His breathing shifted from ragged gasps to an even rhythm, his pulse gaining steady mechanical strength.
His eyelids fluttered open, exposing bloodshot, bewildered irises.
Recognizing the fully armed silhouette in tactical gear and the gleaming obsidian beast perched on the workbench, the young blacksmith tensed, his trembling fingers reaching for his hammer before exhaustion dragged his arm back to the floor with a hoarse gasp.
"Conserve your breath, Apprentice Smith. If I were a scavenger, your corpse would be in the melting crucible,"
Lynn said evenly, offering a canteen of clean water.
Barlow grabbed the container, drinking in greedy gulps before coughing weakly as clarity returned to his gaze.
He looked up at Lynn: "You killed the hounds outside? Are you here for the alloy steel reserves and the mechanical forge as well?"
"The computerized machine tools upstairs burned out during the first aether storm... but my master's pneumatic forge hammers and thirty tons of high-carbon tool steel survived intact..."
"I swore that while I breathe, these tools will never fall into the hands of illiterate butchers..."
"Scavengers merely waste raw materials,"
Lynn said, unrolling a set of engineering blueprints across the heavy anvil.
"I understand how to integrate ancient runic matrices with heavy mechanical forging to transcend mortal limits."
The parchment displayed a hybrid schematic merging abyssal alchemy with heavy manual metalworking: [Tier-0 Peak Runic Stealth Combat Suit & High-Frequency Kinetic Blade Forging Specifications].
The drawings outlined exact mechanical hammer drop sequences, folding layers for high-carbon alloy steel, oil-quenching isotherms, and intricate hand-chiseled aetheric channels integrated with Living Wood-Spirit Fiber.
As a prodigy immersed in iron and heavy hammers since childhood, Barlow's gaze locked onto the blueprint with unbridled awe.
His calloused fingers traced the complex schematic as his voice shook with reverence:
"This... this integrates ancient runic aether conduction with folded forging methods?! Using hand-chiseled runic grooves to replace fried electronic circuits... and weaving Living Wood-Spirit Fiber as an internal kinetic buffer..."
"If we use the pneumatic hammer to forge alloy plates into these ergonomic curves and etch the channels with diamond chisels, this armor will deflect claws from Tier-2 beasts!"
"Are you... a sovereign alchemist lord?!"
"My identity is irrelevant; what matters is whether you possess the skill to strike the anvil,"
Lynn stated, retrieving a dark gold parchment from his coat: a Soul Vassal Covenant.
"I require your metalworking expertise to maintain the forge, hammer ordnance, and craft runic armor.
You require unadulterated rations, clean water, medical supplies, and absolute physical security within my sovereign territory.
Sign this vassal compact, and your life falls under my protection. You will forge the vanguard of a new industrial empire. Or remain here until the next raiding pack breaches the iron door."
Barlow glanced from Lynn's steady gaze to his own bandaged arm, finding no ambiguity in his choice.
Biting his left index finger, he pressed a crimson drop onto the covenant's central sigil, speaking with hoarse conviction:
"I, Barlow Smith, swear upon the anvil of my ancestors to serve Lord Lynn as a loyal vassal.
So long as your forge fires burn, my hammer and craft belong entirely to your domain, unto death."
A flash of golden light flared from the parchment, dissolving into both their brows and registering Barlow's permanent entry into Lynn's territorial census.
[SYSTEM NOTIFICATION: YOU HAVE SECURED YOUR FIRST DOMAIN VASSAL: 'BARLOW SMITH (TIER-0 PRECISION BLACKSMITH APPRENTICE)'!]
[TERRITORIAL FACILITY UNLOCKED: WEST DISTRICT HEAVY MECHANICAL FORGE WORKSHOP!]
[INTACT MACHINERY REGISTERED: DIESEL PNEUMATIC TRIP-HAMMERS X2, HEAVY CAST-STEEL ANVILS X4, HIGH-TEMPERATURE CRUCIBLE MELTING FURNACE X1, DEEP QUENCHING OIL VATS X2, INDUSTRIAL RUST-PROOF LUBRICANT X4 DRUMS!]
[RAW STRATEGIC INVENTORY SECURED: MILITARY HIGH-CARBON ALLOY STEEL PLATES X20 (TOTAL WEIGHT: 3.2 METRIC TONS)!]
Beyond the primary pneumatic forge hammers, the modular tool racks displayed hundreds of heavy tungsten chisels, diamond-tipped engraving styluses, manual hydraulic bending presses, and specialized polymer quenching oils.
The presence of these purely mechanical metalworking tools completely bypassed the electromagnetic breakdown paralyzing modern computerized machinery.
This meant the underground vault possessed an autonomous, closed-loop production pipeline for billet breakdown, folded forging, high-temperature heat treatment, and manual runic engraving.
Lynn now held every puzzle piece for runic armor fabrication.
Lynn walked to the steel plate racks, using a manual testing file to inspect the material surface.
The hardened file skimmed across the plate, leaving only a faint surface scratch.
The Brinell hardness exceeded HB 350, with excellent impact toughness retained through traditional hot-rolling methods.
When folded and hammered under the heavy pneumatic drop and quenched in aether-infused oil, this alloy could sustain violent magical vibrations without cracking.
Beside him, Barlow cleared slag from the crucible base and loaded high-grade anthracite coal into the firebox to preheat the forge.
"Lord Lynn, the auxiliary diesel fuel holds less than two hundred liters, sufficient to drive the compressor pumps for six hours,"
Barlow said, steadying himself against the anvil.
Though physically spent, his eyes burned with technical focus:
"Yet if we concentrate our efforts, six hours is ample time to fold the alloy billets under the pneumatic hammer and cold-form the primary chest plate and articulated shoulder assemblies!"
"Following your runic blueprints, I can forge and engrave the primary framework of your combat armor before dawn!"
"Drink this half-dose of restorative serum and rest for twenty minutes,"
Lynn said, passing a diluted vial of anti-toxin tonic before walking to the mechanical clutch of the diesel air compressor.
Hauling the heavy flywheel pull-cord, a low, rhythmic piston roar reverberated through the concrete foundations.
The analog pressure needle climbed steadily to eight atmospheres as anthracite fires flared into white-hot incandescence under the forced-air blower.
From a lone survivor in a brewery cellar to an alchemist commanding a heavy mechanical forge, a loyal blacksmith apprentice, and an abyssal companion, Lynn had established his first industrial war fortress on the fourth day of the apocalypse.
Barlow gripped a cherry-red billet of military alloy steel with heavy forging tongs, positioning it squarely upon the pneumatic anvil bed.
Depressing the foot treadle, the ton-heavy mechanical ram dropped with thunderous impact, showering the workshop floor in brilliant orange sparks.
Amidst the rhythmic cadence of colliding steel, ergonomic chest plate ribs and articulated shoulder assemblies took definitive form under the hammer.
The subterranean chamber resonated with the primal tempo of ironworking.
Within Lynn's vision, the strategic blueprint of a self-sustaining industrial dominion was taking definitive form.
Lynn stood beside the bench, using a diamond-tipped engraving stylus to test micro-etched runic channels across a cooled test plate.
Dark mana flowed from his fingertips through the chiseled grooves, resonating with the embedded Living Wood-Spirit Fibers to emit a deep violet shimmer.
This synthesis of abyssal aetherics and heavy manual forging eliminated the crude structural weaknesses of typical wasteland scrap gear, marking the formal inauguration of refined runic ordnance for his domain.
When dawn broke through the snowclouds above, a new generation of runic combat armor—combining obsidian hardness, wood-spirit tensile flexibility, and high-frequency kinetic penetration—would emerge from the roar of this subterranean forge.
