The obsidian-steel blast doors of the Central Containment Dome rose forty feet into the arched granite ceiling of the continental rift.
Around the outer rim of the circular portal, eight massive hydraulic locking bolts—forged from solid titanium and thick as old-growth redwood trunks—anchored the gate directly into the subterranean bedrock. Two hundred tons of First Epoch armor plate rested inside guide tracks lubricated by pressurized grease lines that had somehow survived millennia without drying out into varnish.
In the center of the door, floating above a brushed-brass pedestal terminal, a holographic crest pulsed with slow, steady light: a coiled dragon wrapped around an astronomical armillary sphere:
**[FACILITY CENTRAL CONTAINMENT DOME: VAULT 04]** **[CLASSIFICATION: FIRST EPOCH PLANETARY ROOT ARCHIVE]** **[ACCESS PROTOCOL: SYSTEM ROOT LEVEL REQUIRED]**
In the sacred folklore of the cultivation sects, this portal was feared as the **Gate of the Ancient Creator**.
According to parchment scrolls preserved in the deepest vaults of the Heavenly Sword Sect, the slumbering heart of the ancient Void Immortal slept behind this barrier. Forty thousand years ago, during the Great Blood Gathering of the Seventh Sun Dynasty, thirty-three peak Golden Core patriarchs and five half-step Nascent Soul sovereigns gathered before this threshold. They sacrificed eight hundred years of their collective lifespans, stacked ten thousand top-grade spirit stones, and chanted the nine verses of cosmic repentance for seven days and seven nights.
The gate groaned open by a solitary inch. A single plume of ancient purple aura billowed through the crack, vaporizing twelve elders on the spot and sending the survivors crawling back to the surface with their spiritual meridians burned to cinders. From that day forth, the scriptures warned that the Gate of the Ancient Creator would open only when the universe offered up its own marrow.
Austin stood before the brass pedestal, his Sovereign Hard Hat tilted back on his head.
He reached into his canvas rucksack, bypassed a bundle of heavy-gauge zip-ties, and hauled out the **First Epoch Mk-IV Server Terminal Cube**.
The brass-cased modular cube had seen better days. A smudge of dark compressor grease coated one corner, and a flake of dried cave moss clung to the gold-plated bus pins. Austin brought the cube to his lips and blew a sharp jet of air across the contacts:
*Pffft.*
"Let's see if the root SSL certificate is still valid," Austin muttered, squinting at the micro-contacts through his spectacles. "If some idiot let the root certificate authority expire without setting up auto-renewal, we're gonna have to fish around for a paperclip to hit the reset pin."
Beside him, Li Xiaoyao was practically vibrating with terror. The young sword cultivator held his breath so hard his cheekbones turned mottled indigo, his knuckles bone-white against his scabbard.
"S-Senior..." Xiaoyao whispered, voice thin as tissue paper. "The ancient texts say that to approach the dragon seal without sacrificing ninety-nine pure-blooded spiritual beasts is to invite the Wrath of the Ninefold Oblivion! The ambient array pressure here alone can crush a Foundation Establishment dantian into paste!"
"What array pressure? That's just a fifteen-volt electrostatic charge off the ungrounded brass pedestal," Austin said, glancing at the floor plates with open annoyance. "Whoever installed this pedestal never bonded the grounding strap to the structural rebar. Typical lowest-bidder subcontracting. You get static buildup on dry days, and suddenly every local thinks the gods demand ninety-nine goats."
Austin stepped squarely onto the brass pedestal plate.
The moment his steel-toed work boot made contact, the terminal sensor chirped with a crisp, high-frequency elevator chime:
*Doo-dee-doo!*
Austin aligned the cube's gold bus pins with the terminal socket and pressed it home with a firm, solid click:
*BEEP.*
"Self-signed root cert with perpetual validity," Austin noted approvingly. "At least the plant engineers didn't rely on third-party SaaS vendors who go bankrupt every four hundred years."
Xiaoyao’s eyes bulged. "Disengage... primary interlocks? The seals of the ancient gods... answer to your name?!"
Austin pulled a pair of fluorescent-orange foam earplugs from his pocket, rolled them tight between his calloused fingers, and shoved them deep into his ears. He tossed a spare pair toward Xiaoyao's chest.
"Plug your ears, kid," Austin warned loudly. "Four thousand PSI pneumatic exhaust on twenty-ton bolts isn't something your eardrums want to negotiate with!"
Xiaoyao caught the orange foam plugs with numb fingers. Before he could ask what incantation was required to activate them, the mountain bedrock shuddered.
*KA-THUMP!*
A shockwave hammered through the soles of their boots. The first titanium deadbolt, six feet thick, snapped backward into its recessed cavern sleeve with violent hydraulic recoil.
*KA-THUMP! KA-THUMP! KA-THUMP!*
In rapid, rhythmic succession, all eight titanium bolts slammed back like artillery firing in an enclosed room. As the final latch cleared the frame, pressurized nitrogen blasted from the perimeter seals in a deafening, white-out roar of super-chilled gas:
*PSSSSSSSSSSSSSSSHHHHHHHHH!*
A tidal wave of dense white frost rolled across the flagstones, dropping the room temperature by forty degrees in a split second. Rime coated Austin’s canvas sleeves and frosted the blue brim of his hard hat.
The forty-foot obsidian-steel doors parted down the center seam, rolling back into the granite pockets with a deep, floor-shaking hum:
*SCHWWWWWOOOOOOOOM.*
The legendary Gate of the Ancient Creator rolled open like an automatic supermarket door on a Tuesday morning.
Austin grabbed the handles of his loaded handcart and pushed it forward across the frosted sill:
*Clomp. Rrrrumble.*
"Entrance clearance verified," Austin said, dragging his thumb along the black elastomeric gasket lining the inner door frame. He sniffed his glove. "Fluorocarbon silicone blend with vulcanized reinforcing fibers. Zero ozone cracking, zero dry-rot. When the First Epoch built an airlock, they didn't skimp on the rubber."
Li Xiaoyao stumbled through the fog of freezing nitrogen, his flying sword hanging limply in his hand.
"Two seconds..." Xiaoyao muttered, his voice hollow with shock. "The Gate of the Ancient Creator... yielded in two seconds... to a brass box and a doorbell chime..."
Beyond the airlock, the cavern opened into an expanse that defied mortal imagination.
It was a subterranean sphere over five hundred meters wide—a colossal hollow geode carved straight out of the continental mantle. The curved granite walls were lined with thousands of hexagonal superconducting panels that shimmered with deep midnight-blue luminescence.
Suspended in the exact mathematical center of the sphere—held completely motionless by four massive, humming magnetic levitation gantries—was the **First Epoch Central Planetary Core of Vault 04**.
It was a colossal sphere of solid, transparent quantum diamond, fifty feet in diameter.
Inside the crystalline globe, swirling rings of golden, azure, and electric-violet data filaments revolved in frictionless, hyper-dimensional orbits. They spun with breathtaking precision, pulsing with a deep, rhythmic bass note that vibrated through the chamber:
*THUMP... THUMP... THUMP...*
The pulse didn't hit the ears; it rattled directly against the sternum, thrumming in the bones of anyone standing on the deck.
Four vacuum-jacketed borosilicate glass conduits looped around the sphere, glowing with liquid helium at near-absolute zero and venting sparkling plumes of super-cooled mist into the dark chasm below.
Perforated titanium catwalks, suspended by high-tensile steel cables, spanned the empty void of the geode. All four walkways converged at a wide, circular command platform anchored directly beneath the floating diamond core.
Austin walked out onto the central titanium catwalk, his heavy work boots clattering hollowly against the perforated metal grating:
*Clang. Clang. Clang.*
He stopped midway across the span, leaned over the tubular handrail, and peered down into the shimmering blue abyss.
"Now this," Austin murmured, genuine professional respect in his voice, "is proper server infrastructure. Look at that three-point magnetic levitation gantry! Active feedback stabilization coils with cryogenic damping. Zero mechanical vibration transferred to the core chassis. And look at those helium conduits—seamless borosilicate glass with vacuum insulation jackets! The thermal management in this room is pure art."
Cerberus Pug trotted out onto the catwalk beside Austin. The hound's three flat, wrinkled snouts sniffed the hyper-filtered air. Catching a stray draft of vented helium mist, the middle snout wrinkled, followed by the left and right:
*Achoo!*
The three-headed dog shook its floppy ears, sneezed again in unison, and sat firmly on Austin’s boot to keep its paws off the freezing titanium mesh.
Li Xiaoyao slowly dragged his boots onto the catwalk. The moment he looked up at the fifty-foot floating diamond star, his knees gave out. He collapsed onto the metal grating, tears of religious overwhelm spilling down his cheeks.
"The... the Heart of Heaven..." Xiaoyao whispered, his voice trembling in speechless awe. "The Ancient Dao Source... the Great Loom of Destiny! Look at the golden threads of fate spinning within the celestial crystal! Senior... is this the sacred cradle where the ancient immortals wove the grand laws of karma, life, and death for all living beings?"
Austin looked down at him, resting an elbow on the handle of his five-foot pipe wrench.
"No, it's the regional server node for Vault 04," Austin said flatly. "Think of it as the central nervous system for all the automated plant sub-systems. It handles power distribution across the grid, schedules the airlock scrubbers, runs the logic engines for the trial simulators, and keeps the perimeter environmental seals from failing. If the threads of fate look golden, it’s because the primary data bus is gold-plated to prevent corrosion. High conductivity, low signal degradation. Basic networking, kid."
Austin pushed the handcart forward to the circular platform.
In the middle stood a massive octagonal supervisory console forged from dark brushed alloy. Floating three feet above the console surface was a spherical array of semi-transparent holographic monitors, flickering with millions of lines of rapidly scrolling text.
Unlike the calm blue pulse of the floating quantum core above, the console monitors were bathed in an angry, pulsing crimson glare.
Warning glyphs strobed violently across dozens of diagnostic tiles:
Austin leaned over the octagonal console, scanning the error codes with professional familiarity.
"Twelve computing blades missing in Sector B..." Austin chuckled, tapping his chin with the dull end of his yellow grease pencil. "Well, of course they're missing. I stripped them out of rack four ten minutes ago to upgrade our blast furnace readings back at Sunset Peak."
He scrolled down to the next alert.
"Thirty-six sentry drones disassembled for component salvage... Right, that was the batch with the high-torque stepper motors and ceramic bearings. Those are going straight onto our structural drill rigs."
Finally, his eyes settled on the blinking red banner at the bottom: *OMEGA TERMINAL THREAT - UNIDENTIFIED BIO-ENTITY AT PRIMARY AIRLOCK.*
Austin took the yellow pencil from behind his ear and tapped the blinking red box:
*Clink.*
"Well, look at that," Austin said with a wide grin. "The facility thinks someone broke in, stole the computing hardware, scrapped the perimeter security, and hacked the front door. The system administrator is finally logging in to file the incident report."
