The counterweighted hoist car dropped down the main shaft with a smooth, oiled hiss.
Austin stepped out onto the mirror-polished obsidian floor tiles of Subterranean Floor 1, fifty meters down into the bedrock. His steel-toed work boots struck the stone with the heavy, unyielding authority of Level 35. Around his shins, the eighty-four tiny river pebbles, pine needles, and Cold-Iron shavings circled in their three concentric orbits, humming like well-balanced micro-flywheels.
Waiting on the landing platform at rigid military attention was Acting Plant Superintendent Tie Kuang.
The former warlord stood broad and thick as an anvil. His yellow hard hat caught the harsh white glare of the overhead shop lights, his neon-orange vest was spotless, and he held a heavy bronze-trimmed clipboard against his chest like an imperial officer presenting battlefield dispatches.
"Report, Superintendent Tie," Austin said, his voice flat and businesslike.
Tie Kuang brought his steel-plated boots together with an echoing *CLANG*, bowing from the waist at a crisp, mathematically verified forty-five-degree angle:
"Reporting to the Patriarch! During your five-day expedition to Canglan Citadel, Subterranean Floors One, Two, and Three maintained ninety-nine point nine eight percent overall equipment effectiveness! The four high-frequency induction smelters processed thirty-six metric tons of raw spirit iron into two thousand and sixty standardized ingots of Tier 4 Stellar-Steel! Total scrap rate held to zero point zero four percent! Floor Three closed-loop geothermal cooling maintained return water at eleven point eight degrees Celsius! Zero ground faults! Zero OSHA safety violations! Zero lost-time workplace accidents across all three operational shifts!"
Austin nodded slowly, unholstering his yellow wax grease pencil from behind his ear to sign Tie Kuang’s daily log sheet:
*Squeak, scritch.*
"Solid numbers, Superintendent," Austin said, handing the logbook back. "Clean shift sheets, tight metallurgical tolerances, and zero unpermitted downtime. That is how an industrial plant is supposed to run."
Austin thumbed over his shoulder toward Jiang Taixu, who was stepping out of the elevator car. The four-hundred-year-old sovereign carried two eight-hundred-pound crates of precision tooling on his shoulders, his blue carpenter’s pencil tucked behind his right ear and his dark UV safety goggles gleaming under the shop fixtures.
"This is Jiang Taixu," Austin introduced casually. "He's our new independent framing subcontractor. Signed a Form 1099 equivalent back at the capital. His flying sword intent has a clean, razor-thin spatial severance profile. Put him to work down in the southern timber gallery ripping six-by-six cedar timbers into twelve-foot framing studs at zero point one millimeter tolerance."
Tie Kuang’s stony eyes locked onto Jiang Taixu.
Jiang Taixu shifted the crates on his shoulders, meeting the former warlord's gaze through his tinted lenses.
Both men wore heavy industrial denim and work boots. Both carried carpenter pencils behind their ears. And deep within their chests, both possessed Golden Cores that had been hammered into spinning mechanical gears by Austin’s five-foot blue pipe wrench.
Between them passed the silent, profound understanding of two old warriors who had laid down their swords to build something that actually lasted.
"Welcome to the site, Brother Jiang," Tie Kuang grunted, his gruff voice softening with genuine professional respect. He unclipped an unissued yellow hard hat from his tool belt and held it out. "Safety rule number one: watch your footing near the Floor One coolant sump. And sweep up your cedar sawdust at the end of every shift. Combustible wood dust in an unvented underground bay is a severe flash-fire hazard."
"Understood, Plant Superintendent," Jiang Taixu replied with deep solemnity. He set down the heavy crates with feather-light control, pulled off his green headband, and fitted the yellow hard hat snugly over his silver hair, clicking the chin strap tight under his jaw. "Disciple shall maintain zero dust accumulation and absolute framing tolerances."

Two hours later, deep down on Subterranean Floor 2, one hundred meters below the grass.
The cool underground air stayed at a brisk eighteen degrees Celsius, circulated by heavy galvanized sheet-metal ductwork humming along the vaulted granite ceiling.
Austin stood before his newest fabrication line, a twenty-four-inch digital torque wrench in his hands.
First, he inspected the foundation pad.
Before leaving for the provincial tournament, he and Tie Kuang had formed and poured an eight-foot-thick monolithic pad of eight-thousand-PSI micro-silica concrete, heavily reinforced with a welded cage of three-inch deformed steel bars. They had kept it sealed under wet burlap blankets for the full twenty-eight-day hydration cycle.
Austin crouched down, running a gloved hand across the gray surface.
The concrete had cured out glassy and dead-flat. The hydration reaction had locked every particle of aggregate into an impermeable crystalline matrix. Zero shrinkage fissures. Zero hairline settlement cracks.
Austin set the torque wrench on the first two-inch Grade-8 anchor stud embedded in the slab. He leaned his full Level 35 weight into the lever:
*CLICK.*
"Torqued to eight hundred foot-pounds," Austin muttered, moving to the next stud. "Pad cured out to eight thousand four hundred PSI. Rock solid. Good thing, too. You try running a fifty-ton ram on green concrete, and the dynamic shock will shatter the pad into gravel within twenty cycles."
Satisfied with the cured footing, Austin stepped back to inspect the completed machine:
The **Fifty-Ton Automated High-Pressure Hydraulic Forging Press**.
Constructed from four massive vertical columns of cold-drawn Tier 4 Stellar-Steel, the beast was powered by a dual-stage gear pump tied directly into the Pelton hydro-turbine shaft down on Floor 3. Heavy-duty steel-braided hydraulic hoses—rated for ten thousand PSI—looped into a central distribution manifold, clamped tight against vibration and sleeved with high-visibility yellow chafe-guards.
"Hydraulic reservoir filled with ISO-forty-six mineral fluid," Austin recited, checking the sight glass. "Lines bled of air. Nitrogen accumulators charged to three thousand PSI."
He stepped up to the operator station, gripped the forged steel control lever, and shoved it down.
*VUMMMMMMMMMMM.*
The twin-acting hydraulic cylinder descended with unstoppable, mechanical authority:
*THUD-WHIR-CLANK.*
An eighty-pound glowing orange billet of raw Stellar-Steel sitting on the hardened tool-steel anvil was stamped into a flawless, mirror-smooth structural ingot in under three seconds!
Clean, repeatable industrial force. Done in three seconds flat. Zero slag splatter, zero hammer marks, zero wasted movement.
"Cycle time reduced by eighty-five percent," Austin grinned, wiping a smear of mineral oil off his cheek with the back of his glove. "That takes care of our structural steel fabrication. Tie Kuang can stamp out heavy machinery components while I'm sleeping."

An hour later, Austin climbed the iron spiral stairs back up to the Central Supervisory Console on Subterranean Floor 1.
He walked over to Cerberus Pug, who lay beside the drafting table happily gnawing on an old cold-rolled steel pipe flange.
Austin unzipped the hound's padded saddlebag, carefully lifting out the twelve-inch matte-black cube: the **First Epoch Machine Terminal Interface Root Core**.
Working with practiced efficiency, Austin drove four heavy expansion anchors into the obsidian wall beside his master switchboard. He slid the black terminal into a welded steel bracket, locking the retention pins into place.
Next, he ran two heavy-gauge copper conductors from the main 480-volt DC bus through a neat run of rigid EMT conduit, torquing the terminal lugs down with an insulated nut driver. Finally, he snapped the six-pin serial bus harness into the cube's north face:
*CLICK.*
Austin reached up and slammed the main DC disconnect switch home:
*CLACK.*
*BEEP-BOOP-CHIME.*
The cyan laser-etched traces across all six faces of the black cube flared with steady, pulsing phosphorescence!
*HUMMMMMMMMM.*
A massive, wide-angle holographic projection blossomed into the cavern.
A glowing, three-dimensional topographical wireframe of the southern continent unfurled across the thirty-foot ceiling. Mountain ranges showed up as pale green vector lines, underground geothermal channels pulsed in warm amber, and deep fault lines were traced in sharp, electric blue.
A crisp system chime echoed through Austin’s HUD:
Austin stepped out onto the elevated steel catwalk overlooking Floor 1.
He leaned his forearms against the brass safety railing, holding a steaming ceramic mug of hot jasmine tea between his gloves.
He looked out over the humming facility below.
The subterranean floor was alive with clean, disciplined industrial motion.
Across the shop floor, the four induction furnaces hummed with deep sapphire plasma fires. The new fifty-ton hydraulic press stamped out structural ingots with a rhythmic, concussive pulse: *THUD... WHIR... CLANK.* Overhead conveyor belts carried crushed ore and limestone flux directly to the charging hoppers without a single shovel raised.
Over in the southern timber bay, Jiang Taixu whistled an ancient sword tune, his eyes steady behind his dark goggles as spatial sword cuts sheared six-by-six cedar timbers into identical twelve-foot studs with surgical accuracy. Beside him, Tie Kuang checked each cut with a brass combination square, grunting in quiet approval.
Down on the obsidian floor by Austin’s boots, Cerberus Pug lay flat across a wool quilt. All three pink tongues lolled out in pure contentment, his stubby tail thumping a steady beat against the stone as he worked the threads of his iron flange.
Austin took a slow sip of hot tea, letting the steam warm his nose.
He looked up at the spinning blue holographic map of Subterranean Vault 04 hovering against the dark granite roof.
The early-game tutorial was officially in the books.
Foundation Establishment was cleared to a hundred percent.
The provincial capital was pacified, locked into an automated daily login bonus that delivered copper and machine oil right to his driveway for the next ten thousand years.
And five hundred kilometers to the west, an ancient, sealed First Epoch underground research facility was waiting for a master contractor with an RFID override keycard to come crack the seals and clean out the server racks.
Austin smiled a quiet, confident, deeply satisfied gamer smile.
He set his empty teacup on the railing, picked up his five-foot blue pipe wrench, and rested the heavy tool across his shoulder.
"Subterranean Vault Zero-Four," Austin murmured into the warm shop air. "Time to go speedrun some pre-collapse server ruins."
Season 3 was in the rearview mirror.
The Main Sequence Spark was lit.
And Season 4: *Secret Realm Speedrun* was officially cleared hot.
