To an electrical utility contractor, the deep-freeze vacuum of the outer solar system was the ultimate free industrial cryogenic refrigerator.
At forty astronomical units from the sun—out past the icy, eccentric orbit of dwarf planet Pluto—the ambient temperature of deep space hovered at a crisp forty-four Kelvin: minus three hundred and eighty degrees Fahrenheit. At that temperature, you didn't need multi-million-dollar liquid nitrogen chillers, reciprocating helium compressors, or vacuum-jacketed cryogenic transfer lines to maintain electrical superconductivity. You simply bolted your high-voltage transuranic star-jade busways to open structural steel stanchions, and the universe happily provided free, limitless cryogenic cooling for zero kilowatt-hours.
Austin was standing on the primary exterior gantry of *Substation Kuiper-01*, nearly four billion miles from the warm, blue curve of the Azure Cloud Sphere.
The substation was a colossal, two-mile-wide structural hexagonal lattice forged from Vesta nickel-iron and salvaged Harvester dreadnought plate, anchored securely to the surface of a three-hundred-mile-wide Kuiper Belt icy planetoid. Mounted across the lattice were twelve massive, oil-filled transformer banks insulated with synthetic low-temperature polyalphaolefin fluid, seventy-two vacuum circuit breakers each the size of a six-story pagoda, and four enormous parabolic microwave broadcast dishes aimed back toward the inner planets.
Austin was wearing his heavy-duty denim work shirt, his steel-toed boots, and his white supervisor hard hat fitted with dark sunglasses and a clear polycarbonate face shield. In his two hands, he held his five-foot drop-forged alloy steel pipe wrench, bracing his boots against a titanium flange as he hauled on the handle to torque down a four-inch copper-clad star-jade busbar jumper.
*CREEEAAK-THWACK.*
The teeth of the wrench bit deep into the clamping collar. The spring-loaded locking pin clicked home into the detent notch with a sharp, heavy metallic snap.
"Torque verified at sixteen hundred foot-pounds," Austin grunted into his comms, wiping a smudge of cold-tolerant synthetic grease from his chin with the back of his glove. "Jumper Twelve is seated. No phase misalignment."
Beside him on the gantry, Tie Kuang was holding an electronic phase-angle meter connected to the high-voltage termination bushings, while Xuan Ming held the master planetary grid logbook on his aluminum clipboard.
Tie Kuang peered at the illuminated digital screen, his gravelly voice thick with professional satisfaction:
Tie Kuang swallowed hard, his eyes wide as he looked at the glowing numbers.
"Austin," Tie Kuang said, his thick eyebrows frosting over with a thin sheen of atmospheric condensation inside his clear helmet. "Look at that line resistance. Zero point zero zero zero ohms across nearly four billion miles of wire. The voltage from Sunset Peak to the Kuiper Belt doesn't drop even one millivolt. It's like having a solid copper bar running directly from your kitchen outlet out to the edge of the galaxy."
"That's why we used r-process star-jade instead of copper wire," Austin said, tapping the heavy pipe wrench against the steel rail. "Copper at four billion miles would have seventy thousand ohms of line resistance. You'd burn fifty exawatts just heating up the vacuum between Jupiter and Saturn. Star-jade has a zero-energy Cooper-pair gap. It moves electricity with zero friction, zero thermal loss, and zero dielectric breakdown. Though with an eight-inch line running four billion miles, the speed-of-light propagation delay is roughly five and a half hours each way. If Emperor Wu trips a breaker back on Earth, we won't see the indicator light flicker out here until after lunch."
Tie Kuang reached into his insulated thermal lunch pail and pulled out a rock-hard, frozen blueberry turnover.
"Speaking of lunch, Austin... my pastry froze solid in the airlock. Do you have a heat gun?"
Austin sighed, gesturing toward his waist. "Hold it two inches from my belt buckle for three seconds. But don't touch the trapped photon ring, or you'll vaporize your pastry into plasma."
Tie Kuang carefully extended the turnover on a clean pair of bronze tongs, holding it two inches from Austin's waist. The intense, blindingly hot trapped sunlight orbiting Austin's hip bathed the pastry in golden warmth. Within three seconds, the blueberry filling began to bubble merrily, and the golden-brown crust was piping hot and steaming in the thin air of the observation dome.
"Perfection," Tie Kuang grinned, taking a warm, happy bite. "The Lord Architect's waist-mounted microwave oven."
Xuan Ming stepped up to the edge of the gantry, gazing back toward the distant, tiny pinprick of golden light that was the primary sun.
From forty astronomical units out, the sun was no longer a blazing, blinding disk that filled the sky. It was a brilliant, diamond-like star, barely distinguishable from the surrounding sea of celestial lights, save for the faint, shimmering halo of the twelve-thousand-mirror Dyson swarm and the purple thread of the star-jade cable connecting every planet, asteroid, and moon into a single, unified circuit of golden power.
"Four billion miles..." Xuan Ming murmured, pressing his gloved hands together in deep, reverent contemplation. "In the ancient age of the Heavenly Courts, an immortal emperor who sought to project his divine presence across forty astronomical units would have required ten thousand years of ascetic meditation, three thousand spatial jade talismans, and the sacrifice of an entire mortal realm's spiritual veins. And here... a mortal contractor has connected the sun to the outer darkness using sixteen-inch bolts, purple stone wire, and a five-foot wrench."
Austin pulled his carpenter's pencil from behind his ear, checking off the final item on his clipboard.
"Forget an emperor's presence, Xuan Ming. This is an interplanetary utility grid. With Substation Kuiper-01 online, any mining station, science outpost, or cargo freighter operating anywhere between Mercury and the Kuiper Belt can plug in a standard three-prong twist-lock extension cord and draw free exawatt power. No generators. No coal braziers. No spiritual sacrifice."
Two billion miles away, lingering near the outer rim of the Asteroid Belt, the three hundred-mile dreadnoughts of the Concordat Vanguard—led by the *Hammer of the Empyrean*—were watching the live gauges on their crystal scrying basins in absolute, paralyzed stupor.
Arch-Dominus Wu Ji was slumped on his command dais, his four sapphire eyes staring at the golden grid lines spreading across the solar system map.
"Arch-Dominus..." the sensor elder whimpered, his antennae drooping limply over his ears. "The... the energy grid has locked. They have established a continuous exawatt transmission circuit spanning four billion miles. The entire solar system... from the core star to the outer dark... has become a single, unified electrical machine."
Wu Ji rubbed his temples with trembling golden gauntlets. "What... what manner of mortal civilization builds an interplanetary utility grid before they even invent spiritual void-siphons?"
"They... they do not use spiritual void-siphons, Arch-Dominus," the elder whispered. "According to the intercepted communications... they call it 'municipal infrastructure.' And... their lead contractor has just requested fifty thousand additional three-phase circuit breakers from their orbital foundries."
Back on Substation Kuiper-01, Austin walked over to the edge of the observation platform, leaning against the schedule-40 galvanized steel handrail.
The silence of deep space was vast, serene, and profound.
Deep within Austin's chest, however, the silence was broken by an immense, subterranean resonance.
His core—the five-kilometer dense neutron star seed that had sustained him through Level 85 and Level 88—was shuddering. Under the relentless, accelerating inward pull of its own astronomical mass, the degenerate neutron pressure was reaching its ultimate, absolute quantum limit.
The mass was climbing rapidly: five point zero times ten to the twenty-third kilograms... six point zero... seven point zero.
His local surface gravity was ticking upward: eighty-five G... eighty-seven G... eighty-nine G.
Around his hips, his localized accretion ring—the tin lunchbox, utility knife, brass sharpener, crescent wrench, reciprocating saw, spirit level, and linesman’s pliers—was accelerating its orbit from twelve to sixteen feet per second, while the paper-thin ring of trapped golden photons at his waist glowed with an intense, violet-white incandescence.
Austin checked his resin digital watch.
The display blinked:
`[TIME DILATION FACTOR: 1.000142 -- LOCAL CLOCK DRIFT: 12.2 SEC/HR]`
"Tie Kuang," Austin said, his voice dropping into a deep, chest-rattling sub-bass baritone that vibrated through the metal railing beneath his boots.
Tie Kuang turned around, his eyes widening as he saw the starlight bending sharply around Austin's shoulders into an unmistakable, glowing Einstein ring.
"Austin? What... what is that hum in your chest?"
"The neutron degeneracy pressure is failing," Austin said calmly, tucking his carpenter's pencil into his leather pouch and adjusting the heavy drop-forged wrench across his shoulder. "The mass is passing seven point five times ten to the twenty-third kilograms. In about forty-eight hours, the core is going to collapse past the Schwarzschild radius."
Tie Kuang swallowed hard. "The... the Schwarzschild radius? What happens when it collapses past that?"
"The escape velocity exceeds the speed of light," Austin explained, looking out toward the dark, infinite reaches of the outer void. "The core becomes a rotating Kerr black hole. An actual cosmic dark center inside my ribs. The edge of the void will manifest, dragging space-time faster than light around my torso."
He took a slow, deep breath, testing the ninety-G strain on his spinal support harness.
"Get the heavy lead ballast ready, Tie Kuang. We’re going to need thirteen hundred pounds, and we're going to need the hex-fluid dampers running at thirteen hundred RPM. Because when this core crosses the event horizon, we’re officially entering an OSHA Class-One Confined Space."
Out in the deep cosmic dark, the stars shone brightly upon the four-billion-mile web of gold and star-jade, while the master countdown to Level 90 began its final, unstoppable tick.
