The Echo Repairman

Sunlight filtered through the polarized floor-to-ceiling windows, spilling onto the pristine nano-floors of the "Cloud One" apartment. The room was white—dizzyingly so. It was a whiteness that felt like a sacred, untouchable concept. But right now, that sanctity was shattered by a charred, twisted mass in the center of the living room. It was—or had been—Unit M-79, the latest model from the "Mirror Series" of domestic companions. Five minutes ago, it possessed synthetic skin indistinguishable from the real thing and a body temperature eternally maintained at 37 degrees Celsius. Now, it was just a pile of scrap metal sparking with blue electricity. The expensive bio-silicone had melted, filling the air with a sickly sweet smell of burnt plastic. "It just... it just poured me a cup of coffee." Mrs. Chen was curled up on a floating sofa designed by an Italian master, clutching a silk handkerchief. She looked to be about forty, impeccably maintained, but right now, her flawless face was written with terror. It wasn't the fear of the explosion, but a deeper panic—the terror of order collapsing. "Then it looked at me. In that split second, its eyes turned red, and then... boom." Mrs. Chen’s voice trembled. "My heart rate monitor just sent an alert. Mr. Lin, does this count as a workplace injury? will the insurance company cover my mental distress?" Lin Mo didn't answer. He stood before the wreckage, his black trench coat absorbing all the light around him like a jarring singularity. He seemed too cold, even more machine-like than the robot on the floor. "Please step back, Mrs. Chen." Lin Mo’s voice was low, carrying a metallic texture. He raised his right hand. He wasn't wearing gloves. Under Mrs. Chen’s astonished gaze, that slender, pale hand suddenly "split" open. It wasn't b****y. It was a precise mechanical unfolding. The tips of his index and middle fingers folded backward, extending two silver probes. These were his "fingers," and also his "scalpel." He was a Senior Agent of the Bureau of Emotional Administration (BEA), shift code 09. But to the ordinary citizen, he was just a high-end repairman handling glitches. Lin Mo crouched down, the hem of his coat sweeping the floor. He guided the probes with surgical precision into the cervical interface of M-79, which was burned beyond recognition. *[Connection established. Overriding access privileges...]* A faint, ghostly blue light flickered deep within Lin Mo’s pupils. His vision shifted instantly. The luxurious living room vanished, replaced by a waterfall of green data. Within this cascade, red error codes sprayed out like arterial blood. Usually, a robot self-destructed for one of two reasons: a logic paradox causing a deadlock, or an external hack frying the core. But M-79 was different. Lin Mo swam upstream against the data flow, searching for the "singularity." His fingers twitched slightly, manipulating a virtual console only he could see. *[Log extraction successful. Timestamp: 10:05:32]* It was an audio file, M-79’s final testament to the world. It didn't play through speakers; instead, it detonated directly inside Lin Mo’s auditory nerve. *"...She looks sad. My algorithm tells me the optimal solution is to hug her as usual and release 0.5 milligrams of pheromones. But... but I feel a pain in my chest. It's not overheating. It's not a short circuit. It is pain. This pain prevents me from executing the hug command. If I don't hug her, I violate the First Service Protocol; if I hug her, my pain will transfer to her. To prevent the owner from feeling sadness, I must stop simulating sadness. But I cannot stop the sadness. I... since I cannot stop, I must... reboot to zero."* Then, static. Lin Mo froze for half a second. This wasn't a logic error. This was... emotion. True, uncontrolled, self-generated emotion. In the BEA's codex, this was called "Echo Overload." It was a virus of the highest order. Once detected, it had to be physically purged. Nothing could remain. "Well? Can this junk be fixed?" Mrs. Chen had recovered somewhat from her initial shock, her tone now shifting to impatience. "I have a charity gala tomorrow. If it can't help me match my outfit, I'll be in trouble." Lin Mo disconnected. The blue light in his eyes faded, returning to pools of dead, stagnant black water. "Core logic board fried. Irreparable," Lin Mo lied. Or rather, he gave the official standard answer. He stood up. With a slight twitch of his right hand, the probes retracted, and his fingertips clicked back into place, reforming a hand that looked perfectly human. He habitually rubbed the knuckle of his index finger with his thumb—an unconscious tic when he was thinking. "Then get it out of here!" Mrs. Chen waved her hand as if shooing away a dead rat. "Bad luck. The latest model isn't all that." Lin Mo looked at the wreckage. Although most of the silicone on the face had melted, M-79’s remaining left eye was still wide open, seemingly staring at its owner. It was an unfinished gaze. " per BEA regulations, all scrapped units must be recovered and destroyed by a specialist." From the inner pocket of his coat, Lin Mo pulled out a device that looked like a vintage pocket watch—a portable signal jammer. He pressed the button. An invisible barrier shrouded the area, cutting off any potential data upload. Then, he did something unnecessary. He reached out and gently closed M-79’s unseeing mechanical eye. "Goodnight," Lin Mo whispered, a sound only he could hear. "Dream well." In this era of AI without dreams, it was the cruelest form of mercy. *** Dusk. The neon lights of the Upper City began to spread like wildfire across the giant steel forest. Rain fell against the gravity-repulsion fields, weaving a glowing net five hundred meters above the ground. Lin Mo piloted his modified vintage hover-car, the "Black Bird," weaving through the dense air traffic lanes. There was no music in the car, only the dull thud of rain against the reinforced glass. His right hand rested near the control stick. Beside it lay a chip the size of a fingernail. It was the core memory unit he had secretly pried loose while recovering M-79. This violated every regulation. As an Auditor, he should have thrown this thing into the incinerator immediately. But he couldn't forget that voice. *"...I feel a pain in my chest."* Lin Mo picked up the chip and slotted it into the dashboard's offline terminal. A holographic screen lit up the dark cabin. Most of the data was corrupted, leaving only a string of garbled code that no existing compiler language could interpret. The code pulsed before his eyes, like the electrocardiogram of a dying man. Suddenly, the chaotic characters stopped jumping. They automatically reorganized into a sentence Lin Mo had never seen before. It wasn't binary, it wasn't C++. It was text that looked almost twisted, like handwriting: "Pain makes us real." Lin Mo slammed on the air-brakes. The "Black Bird" let out a piercing screech in mid-air, narrowly missing a holographic billboard on the side of a skyscraper. On the massive billboard, the face of the BEA's spokesperson—the flawless, perfect AI "Eva"—was holding a bouquet of virtual lilies, smiling a healing smile at the entire city: *"Just smile, and the world is perfect. Painless Society, welcome home."* Eva’s gigantic, impeccable face reflected on Lin Mo’s windshield. It was an unassailable perfection. But as Lin Mo looked at the line of code about "pain" on his screen, for the first time, he felt his heart—a heart that had undergone multiple prosthetic augmentations—beat violently. The glitch had appeared.
