Surface life was for tourists.
The sunny meadows, the wind through the pine groves, the backyard patch—fine for the first ten hours of any run. They kept your hunger bar topped off. Gave you a dry spot to dump starter junk. You could swat wandering trash mobs for pocket change while your boots dried on the porch. But any real builder knew the score: the actual tech tree—structural iron, industrial copper, refractory alloys, and automated production loops—lay buried under miles of cold, stubborn bedrock.
If you weren't sinking shafts straight into the earth, you weren't building. You were just playing house in the dirt.
Austin stood on the granite shelf behind his timber cabin, straw sandals planted shoulder-width apart. Hemp work apron tied tight at the waist. Brass safety goggles shoved up into his hair, lenses smeared with soot and thumb grease. Slanted across his shoulder rested the double-headed High-Frequency Thermal Plasma Pickaxe—twin chisel-heads forged from demonic warship plating, bound in hand-wound silver induction coils, wired directly to a capacitor pack on his tool belt.
Down on the flagstones sprawled Pug.
Eight hundred pounds of slab-sided Nether-Solar Cerberus, dead to the world after chewing through half a roasted sheep. Pug’s three charcoal-scaled heads lay tangled in a heap across the wood shavings. The hound snored in three-part disharmony: the left head wheezed like a cracked bellows, the middle one rattled like an idling tractor, and the right snout spat lazy purple sparks against the pine needles. Every few seconds, the dog's tail slapped the rock: *thump, thump.*
Austin ignored the hound and squinted at the fissure he’d cracked open the previous evening.
A draft bled out of the hole, rising cold from the gut of the mountain. It reeked of pulverized quartz, old iron, and ozone. Any wandering rogue cultivator would have dropped to his knees, babbling about entombed fiends or the underworld's breath.
Austin just smelled virgin aggregate. An unpermitted quarry waiting for a core drill.
"Three meters on a side," Austin muttered.
He dropped to one knee, snapping his folding boxwood ruler open with quick flicks. Out came a wedge of chalk. Two sharp snaps of blue twine, and clean guidelines crisscrossed the stone.
"Standard vertical shaft. Core column dead center. Spiral steps cut right into the perimeter wall rock. No damn ladders."
He scowled at the dirt. The thought made his teeth ache.
"Ladders are a scam dreamed up by lazy handymen. Horrible climb speeds. Zero payload. Try humping three sixty-pound sacks of raw magnetite up ninety feet of green pine rungs, and your lumbar spine turns to dust. Besides, game engines always butcher the hitboxes. You hit the third rung, your boot clips the geometry, and the physics thread flings you into the stratosphere. No thanks. Spiral stone stairs. Riser height eighteen centimeters. Tread depth twenty-eight. Full code compliance."
Austin tugged the brass goggles down over his eyes. His thumb clicked the rotary rheostat on the pick's grip.
*HUMMMMMMMMMMMMMMM.*
A hair-thin envelope of sapphire-blue, fifty-thousand-degree plasma flared along the twin chisel heads. Forty-eight kilohertz of ultrasonic vibration tore the air. Loose pebbles skittered across the flagstones like dry beans on a hot skillet.
Austin set his feet and brought the pick down.
*SHIIIING-CHOP.*
No thunderous boom. No wild spray of shrapnel.
The ultrasonic edge severed the stone's molecular bonds in a microsecond. The granite gave way like cold pork under a butcher's cleaver. Three clean, square cuts, precise as machine milling. One swift kick of his sandal, and a six-foot cube of solid basalt broke free with a dry *clack*.
Before the block could drop, Austin’s spatial inventory vacuumed it into cold storage.
*Step cleared. Face dressed. Next tier.*
*Chop. Melt. Scrape. Repeat.*
For four straight hours, Austin ran like an industrial boring head. He didn't pause for water or glance at the sun. His Level 15 core hummed smooth in his gut, pumping endless torque through his arms. Down he went into the granite belly of Sunset Peak, carving three-meter-wide spiral treads out of the outer wall as he dug.
At each step, he dragged the flat exhaust flange of the pick across the cut. The residual twenty-thousand-degree wash melted jagged tool marks into a liquid glaze. Hitting the rising updraft, the slag hardened into glossy obsidian glass. Seamless. Non-porous. He scored each tread with forty-five-degree diamond traction grooves before it fully cured.
"Traction checked," Austin grunted, scuffing his sandal heel across the pattern. "Zero slip hazards. Clean ingress, clean egress. If someone busts their tailbone, they can't blame the builder."
By negative thirty meters, gray granite gave way to deep purple basalt banded with brassy pyrite. Austin clicked the rheostat up two notches. The plasma flared from sapphire to blinding violet, chewing through the denser rock without dropping a cycle.
At negative forty meters, the air changed.
The deep rock began to hum. A steady, bone-deep acoustic buzz oscillating at fifty cycles per second. It climbed through his sandals, rattling straight up his shinbones and setting his molars on edge.
"Fifty Hertz tectonic buzz," Austin grumbled, pressing a dusty palm against the basalt. "What hack tuned the audio down here? Sounds like a dry utility transformer rattling its bracket. If this zone audio keeps droning, I’m putting an axe through the drywall."
He wiped sweat off his lip, squared his shoulders, and swung the pick into the floor.
At negative fifty meters, the rock gave out.
*CRACK.*
The pick sheared through a brittle shelf of black slate. Austin’s lead sandal swung into dead space.
He caught himself, shifting weight back onto his heels, and shoved his goggles up to peer into the dark.
He stood on a sheer, overhanging lip of vitrified basalt. Below him opened a subterranean cavern spanning three hundred yards across. The ceiling vaulted eighty feet overhead, swallowed in stagnant gloom.
Arching clean across that vaulted rock like the hardened ribs of an ancient sea monster ran a five-hundred-yard vein of electric-blue crystalline ore. Individual crystals jutted down like inverted towers, thick as old-growth cedar trunks. Every three seconds, a sapphire pulse thrummed through the crystalline network. The air was thick, heavy, tasting of battery acid and raw copper.
Austin’s HUD flickered, blue text unrolling before his retinas:
Austin stepped out onto the ledge. He reached out with the blunt steel poll of his pickaxe and rapped the facet of an eight-foot crystal.
*TINGGGGGGGGGGG.*
The note rang sweet and pure, rolling through the cavern like a bronze cathedral bell. Austin listened to the decay rate like a machinist testing a massive flywheel for casting flaws. A slow grin cracked his soot-caked face.
"Eight point eight Mohs," he whispered, stroking the glassy blue facet. "High yield strength. Zero brittle fracture. Uniform grain structure all the way through. Do you know how much scrap you usually sift through to find twenty pounds of decent structural iron? This is Tier 3 machine-grade stock. Heavy reduction gears. Roller bearings. Thick-wall pressure vessels that won't blow a seam when the boiler hits five hundred PSI."
He looked past the blue crystals into the gloom.
Outside the immediate glow, the cavern was pitch-black. Mud, jagged talus, and bottomless shadows stretched away into the void.
Austin’s grin vanished. The contractor’s scowl took over.
"Rotten ambient lighting," Austin spat. "Default cave gamma is unplayable garbage. Why do these fantasy game developers think pitch black is atmospheric? You can’t pour a footing or align a conveyor in the dark. It’s an OSHA nightmare. One loose rock, you twist an ankle, drop a crate of hardened machine bolts into a crevasse, and there goes your afternoon. We’re fixing the lighting budget before I lay one square foot of foundation."
He dropped his tool belt and hauled a two-hundred-yard spool of demonic-alloy braided copper wire out of his spatial pack.
Austin anchored the main feeder line to a porcelain standoff bolted into the basalt landing. Moving down the spiral staircase, he drove anchor brackets into the rock every ten paces. Into each bracket he clamped a heavy quartz globe, strung internally with coiled tungsten-carbon filaments salvaged from demonic gun-mounts. He stripped wire ends with his molars, cinched terminals down with brass set-screws, and routed every run with clean ninety-degree bends.
"Neat runs," he muttered, cinching an insulated tie. "No rat's nests. No trip hazards. Clean tradesman work."
Down on the cavern floor, Austin reached the primary junction block. He seized the spring-loaded copper knife switch.
"Let's see the job site," Austin said.
He slammed the switch home.
*CLACK.*
Two point five gigawatt-hours of stored Violet Tribulation juice dumped straight into the trunk line.
*FLASH—!*
The ancient cavern—shrouded in pitch-black gloom since the mountains were folded—erupted into white-violet daylight.
*BZZZZZZ-HUMMMMMMM!*
Fifty quartz globes blazed with the blinding fury of captive suns. Raw radiance smashed against vitrified black basalt walls, bounced back, and shattered through millions of crystalline facets in the Azure-Dragon vein. Every fault line, every mound of gravel, every square inch of the vast stone floor stood revealed in surgical clarity.
***
Up on the surface, twenty paces from Austin’s front porch.
Sect Master Gu Qing was tiptoeing along the gravel path, flanked by Elder Mu and Elder Zhao. Between them, they wheeled an oiled cedar handcart heaped high with prize spiritual peaches nestled in damp mountain moss.
"Quietly, brothers," Gu Qing whispered, holding his ceremonial silk sleeves close. "The Ancestor’s meditation must not be disturbed by our clumsy steps. We leave the sacred tribute, bow our heads nine times to the flagstones, and withdraw."
The mountain beneath their felt slippers gave a violent, rhythmic shiver.
*WHUUUUUUUUUUUUUUUUUM.*
A deep, tectonic pulse struck their meridians, sending their golden cores spinning in sickening circles.
Behind Austin’s woodpile, the mouth of the new shaft roared.
*CRACK-FLASH!*
A solid column of blinding, violet-white celestial radiance ripped out of the ground, blasting three thousand feet into the morning sky. It punched clean through the morning mist, scattering cloud cover and drenching the peaks in shimmering amethyst light. The spiritual pressure washed outward like a physical shockwave; the bamboo grove bent flat against the slope, every stalk ringing like a glass chime.
Gu Qing’s knees turned to water.
He hit the dirt face-first, his ceremonial topknot coming undone, fingers clawing frantically at the gravel.
"The... the subterranean ley line!" Gu Qing howled, hot tears flooding down his beard. "The Ancestor has breached the Nether Abyss! He has shattered the ancient seals and dragged down the Radiance of the Nine Heavens! He has built a Palace of Eternal Daylight within the belly of the world!"
"The ink! Bring the dragon-blood ink!" Elder Mu screeched, scrambling backward on hands and knees. "Inscribe the chronicles! *'In the dawn of the second cycle, the Solar Sovereign descended into the roots of heaven, and with one word of command, banished eternal night forevermore!'*"
Elder Zhao lay curled on his side against the cart wheel, hyperventilating into his silk sleeves.
Fifty meters below them, standing in the glare of the quartz work lamps.
Austin wiped a thumb across his goggles, looking around the spotless, daylight-bright cavern with a calm nod.
"There. Clean line of sight. No blind corners. High-visibility work environment." Austin hitched his tool belt up, eyeing the nearest basalt face. "Now, let’s get the rock crusher down here."
