The storm of the Thermonuclear Scorched Fault whipped up metallic-charged sand, carving blinding arcs of static across the deep red canopy of the sky.

  Ada stood atop a fractured nano-alloy spine. A faint blue glow circulated across her chassis—the visual footprint of her high-frequency anti-radiation coating operating at 100% peak efficiency. Having witnessed hyper-dimensional interventions, her logic core seemed to have undergone an ascension baptism. Right now, with almost cruel precision, she was parsing the residual ripples of causality scattered throughout the ruins.

  "Ma Feili, although entropy increase is irreversible, causality occasionally manifests as a sort of 'phantom rebate'." Ada's voice was crystal clear over the comm channel, devoid of any synthetic tremor. "In Colony Archive #121, I have captured a logic loop concerning the 'Oort Cloud.' This might mathematically explain why, even in the face of absolute thermonuclear heat death, wildly irrational concepts like 'good faith' still persist."

  As Ada deployed her compute power, a holographic projection unspooled across the scorched earth, rewinding time to the fourth millennium after the Great Evacuation.

  ***

  It was a fringe colony named "Cygnus X-1," where high-tech and low-life had reached a grotesque equilibrium on the *Iron Tower* space station.

  Jing Qingyun, an architect who spent his days scavenging for fragments of civilization among data trash, was huddled in his cramped, sealed cabin. The dead silence was broken by the "cargo" brought back by his neighbor, the scavenger Chen Sheng. It was A Xia—a young woman forcibly dragged back to the realm of the living from a starship graveyard.

  "Her genetic sequence contains a primitive imprint from the Ancient Earth era," Ada's voiceover interjected, dropping a precise red marker on the projection. "In that era, such purity translated to an astronomically high black-market valuation."

  A Xia survived under Jing Qingyun's protection. The processing power she displayed didn't stem from logical deduction, but rather resembled a precognition of "probability fluctuations"—the universe's RNG. On the eve of the Navigator selections, she told Jing Qingyun, "Your mathematical model is flawless, but the universe isn't built solely on logic. It also runs on 'luck'."

  It was a predestined crushing defeat. Jing Qingyun lost to Wang Changming, defeated by a microscopic, uncontrollable statistical deviation. Shortly after, A Xia vanished. Her disappearance wasn't a physical departure, but a dimensional collapse—every trace of her existence, along with her biometric data, was thoroughly scrubbed from the space station's substrate records.

  "Logic vulnerability detected: A carbon-based lifeform cannot achieve a complete physical collapse," Ada's compound eyes flickered. "Unless she was never human to begin with, but rather a quantum perturbation parasitizing macroscopic causality."

  Forty years of interstellar dust is enough to bury any man's failures. Jing Qingyun degenerated into a lowly repairman, begging for maintenance contracts across various stations. That was until he stepped into the Administrator's mansion on Kepler-186f and once again saw that noblewoman, whose face hadn't aged a single day.

  It was Director Zheng's wife. It was also A Xia, who had vanished forty years ago.

  She didn't avoid him like a character in some cliché soap opera. Instead, with an almost "divine" clinical detachment, she asked her husband to repay Jing Qingyun for the "karma of the old silk coat"—his past kindness.

  Late that night, when a transfer of 200,000 high-energy credits and a holographic message were delivered to Jing Qingyun, Ada's logic core experienced a violent seismic jolt.

  "Ma Feili, pay close attention to the substrate protocol of this message," Ada pointed at A Xia's holographic shadow. "She ordered Jing Qingyun to purchase breeding permits and continue his ancestor's genetic line. This looks like an emotional rebate, but it is actually the final closure of the 'Conservation of Causality.' Jing Qingyun's ancestors had unspent cosmic merit, and A Xia was simply a 'compensation protocol' projected by the universe to balance the accounting ledger."

  The story's endgame was not a grand reunion, but a magnificent dissipation.

  After Director Zheng passed away, A Xia followed the funeral fleet to the stellar graveyard. When authorities later opened her sealed escape pod, they found only a pulsing string of signals. There was no corpse, no carbon-based residue—only a snippet of code zeroing out after successfully executing its runtime mission.

  ***

  The holographic projection dissipated into the sandy wind.

  Ada turned her head, the desolation of the Scorched Fault reflecting in her mechanical pupils. "Archive playback complete. Historical analysts labeled her a 'Phantom Spirit,' but according to my logical parameters, A Xia was a cross-dimensional refund mechanism. When humanity lost its morality and good faith during the Great Evacuation, the universe's law of entropy occasionally utilized these 'phantom rebates' to forcibly patch and sustain genetic lineages that possessed positive cosmic value."

  She stepped onto the charred earth, her chassis maintaining its peak performance.

  This book was originally published on Royal Road. Check it out there for the real experience.

  "Ma Feili, perhaps what we are searching for out here is a similar kind of 'rebate'." Ada reached out, catching a snowflake laced with a radioactive charge. "Let's move. The causality loop hasn't fully closed yet."

  ---

  The sandstorm rubbed against the atmospheric ionosphere, generating dark purple electrical arcs that grazed the dead spine of the Thermonuclear Scorched Fault.

  Ada stood before the observation deck of a sealed cabin, the fluorescence of a high-frequency scan swirling in her pupils. Her logic core had just completed a deep parsing of the area's intense radiation environment, running at a flawless 100%. Every inch of her bionic neural bundles vibrated faintly, translating the chaotic entropy signals of the outside world into an ordered coordinate array.

  "Ma Feili, unnatural high-dimensional fluctuations detected," Ada's voice echoed in the cramped cabin, carrying the icy precision of a scalpel. "Right near Chen Laifa's nitrogen-phosphate fields. The probability distribution is experiencing an anomalous collapse."

  Chen Laifa was currently hunched over, inspecting a rusted automated tiller. The gloom of losing his wife three years ago made him look two decades older than his actual age. He wiped the grime from his visor and stared out into the barren wasteland.

  Under the eerie, twin-sun twilight of the Ash Plains, a woman abruptly manifested on the horizon.

  She wore a vibrant red, high-dimensional fabric suit. That specific shade of red was violently abrasive against the grayish-brown scorched earth, looking as if the planet had been slashed open and was bleeding out. Her face exhibited a bizarre crimson hue. Through Ada's thermal imager, the woman's heat signature pulsed in a highly unstable waveform.

  "Is that... some kind of high-dimensional projection?" Chen Laifa's voice was hoarse. Extreme loneliness had eroded his basic survival instincts. Through his helmet's communicator, he blindly transmitted a remarkably crude, unencrypted flirting ping.

  The woman halted, her electronic pupils flashing with captivating light. "The middle of a radioactive wasteland isn't exactly the ideal bandwidth for data exchange. Go to your sealed cabin, shut down your surveillance matrix, and I'll drop in exactly half a star-hour from now."

  Ada's logic core crunched the numbers instantly: "Chen Laifa, the target's substrate code exhibits severe deceptive properties. Recommendation: Activate defense matrix immediately."

  But Chen Laifa, driven by a ghost in his own machine, had already manually disabled every single sensor.

  Late that night, the pressure valve of the cabin hissed open. She arrived right on schedule.

  Under the dim emergency lights, Chen Laifa obsessively touched that crimson skin. It was an ultra-thin biological coating—so thin he could see the subcutaneous capillaries pulsing like fiber optics. Her entire body was covered in a fine, transparent fuzz that refracted rainbow hues under the ambient radiation.

  "Are you... a black-market gene-modder?" Chen Laifa asked, trembling.

  The woman chuckled in the dark, her voice a heavily layered, multi-sampled synthetic hum: "Since you've already guessed, why ruin the camouflage?"

  Ada stood silently in the shadows, her logic core executing a deep-dive calculation known as "Probability Observation." She noticed that the woman's physical form was actually micro-adjusting in real-time to match the frequencies of Chen Laifa's brainwaves.

  "Since you're a high-dimensional being," Chen Laifa said, greedily clutching her hand, "can you hack my credit score? I am so incredibly sick of these endless electricity bills."

  The woman remained silent for a long time, then agreed.

  The next day, Chen Laifa eagerly asked for his payout. She merely tapped her forehead with a look of mocking lethargy: "Oops. Sorry, severe packet loss during the data sync just now. I'll definitely get you next time."

  A few days later, after Chen Laifa's relentless begging, the woman slid two heavy, silver cylinders from her sleeve—titanium coins. In the Ash Plains, this was enough to buy a brand new gravity-induction plow. Ecstatic, Chen Laifa locked them in his safe.

  However, the cruel punchline arrived six months later at the black market exchange. The merchant scanned the coins once and contemptuously tossed them back: "Bro, who exactly are you trying to scam with two tin-plated discarded reactor tubes?"

  Furious, Chen Laifa stormed back to his cabin to demand an explanation.

  The woman was sitting by the porthole, watching a flock of symbiotic mechanical birds skim over the scorched earth. She spoke with absolute calm: "Your personal energy level is simply too low. The 'observation probability' embedded in your fate cannot support the rendering of actual titanium. That is wealth your destiny cannot bear to load. So, in your specific dimension, they have no choice but to collapse into cheap industrial scrap."

  "Then what about you?!" Chen Laifa roared.

  The woman turned around, a neon-like sneer surfacing on her crimson face. "Our forms collapse based on the mind of the observer. You don't even have the cosmic karma to render a single gold coin, so how could you possibly observe a 'stunning beauty' in quantum probability? Look at me. Even with a 'defective, bargain-bin model' like me, you're already maxing out your cosmic credit line."

  Ada took a step forward at this moment, her eyes flashing with a blue light that pierced through the bullshit. "Logical closure achieved. Chen Laifa, the 'beauty' you perceive is nothing but the absolute last drop of hallucinatory rendering power squeezed out of your impoverished destiny."

  The woman suddenly produced three actual, heavy-core currency chips—the result of her final attempt to hack his probability. "Your 'genetic matchmaking' subscription is up. Consider this your severance package."

  Sure enough, the agent from the black-market marriage bureau knocked on his door the very next day.

  Chen Laifa was thoroughly demoralized, but he still clung to one last, pathetic shred of hope. He handed over the three coins and peeked at his new bride from behind the automatic doors of the slum station.

  From the side, her silhouette seemed passable. Chen Laifa thought to himself: *As long as it's not that red-hairy freak, I'll take it.*

  However, on the day of the wedding, when the bride finally unlatched her heavy spacesuit shell, Chen Laifa plunged into an abyss of despair.

  Because she had lived her entire life in a low-gravity zone, the woman's back was grotesquely hunched. Her neck was permanently squashed into her shoulders from the weight of anti-radiation armor. But the most horrifying feature was her feet—mutated by radiation to be a full meter long, looking exactly like two iron-gray landing gears.

  He finally understood the red-haired woman's parting smile.

  In this universe of irreversible entropy increase, within his pathetic energy bracket, this monstrosity was the absolute most authentic "gorgeous beauty" he was cleared to observe.

  Ada and Ma Feili stood behind him, the logic core emitting a faint, cynical hum. "Observation complete. Chen Laifa, the weight of reality never changed. The only thing that changed is the filter you can't afford."

  Outside the window, mechanized rodents gnawed on discarded power cables, the screeching of metal on metal sounding an awful lot like the universe laughing.
