He closed the iron box and stuffed it back into the bottom of the wardrobe. The old wooden boards let out a faint creak under the pressure. As he turned, his gaze fell on the kraft paper file folder on the desk. The mouth of the bag was sealed tightly with wound cotton string. It was bulging, its edges stretched to a slight sheen, like a swollen, silent heart. Outside the window, the night was thick as ink. 2:47 AM. Four hours until dawn, six hours and thirteen minutes until the meeting time agreed upon with his "assistant," Gu Zhixing. Time was like a taut string, pulled tight along his spine; with every breath, he could feel that intangible pressure tightening. He walked to the desk and pulled out the chair. The bearings of the old swivel chair made a dry, grating sound. He twisted on the desk lamp. A dim yellow circle of light *snapped* into place over the desktop, its edges blurred, like a fragile, isolated barrier. The file folder lay within the light, the kraft paper glowing with a stale yellow hue. The smell of ink mixed with the dry, paper-specific scent, threads of it worming their way into his nostrils—a blend of dust, old warehouses, and the particular, icy odor of some bureaucratic institution. He pulled the paper cutter from the pen holder. The stainless-steel blade reflected the lamplight, drawing a cold, fleeting arc. Lu Chenzhou's hand was steady. Steady like a surgeon's scalpel cutting through the first layer of skin on the operating table, or like the final half-second of stillness before a firing squad shooter squeezes the trigger. The tip of the blade pressed against the cotton string, applying slight downward pressure, then slid smoothly across. *Sssshhh-rip—* The sound of the cotton thread snapping was minute, but in the dead silence of the room, it was piercingly clear, like tearing through some taut membrane. He set down the knife. The cool metal handle made a light *clack* against the wooden desktop. Using his fingertips, he pried open the sealed mouth. The edge of the kraft paper was rough, scraping against his finger pads. On top were several color-printed photographs. The paper was smooth, the pixel resolution high, clearly taken with a professional telephoto lens, surreptitiously. The photo showed a middle-aged man wearing a faded gray jacket and a dark baseball cap, pushing open the door of a convenience store. A profile view, a slightly hunched back, his left hand holding a translucent plastic bag, inside which the outlines of instant noodles and cigarettes were faintly visible. It wasn't the face—the photo angle didn't show the full face clearly. It was the gait. That almost imperceptible drag as the left foot stepped forward, the unconscious forward lean of the right shoulder, the entire body's center of gravity skewed left and forward. It was muscle memory formed over years, like a code etched into the bones, harder to disguise than one's appearance. Ten years ago. A rainy night. The mouth of an alley in the old city district, puddles reflecting the dim glow of streetlights. The informant codenamed "Old K," turning to leave, his soaked back looked exactly like this—the slight limp left by an old injury to his left leg, unconsciously revealed when tired or tense, like a silent scar. Lu Chenzhou's fingers pressed down on the edge of the photo, his fingernails turning white from the pressure, the knuckles standing out in sharp relief. Old K was dead. Official records, eyewitness testimony, even blurry photos existed to corroborate the identification of the body. In the vortex of that political murder case ten years ago, Old K, as a key informant, had "died accidentally." It was the beginning of the break in his chain of evidence, one of the forces that had pushed him to the brink, ultimately forcing him to sign that forged confession. A dead symbol. An anchor of guilt. He took a deep breath. The cold air flooded his lungs, bringing a brief clarity. He pushed the photo aside. The paper slid across the desk with a soft *swish*. He picked up the background investigation report underneath. Printed on A4 paper, neatly bound, the header bore the watermark of Shen Yan Group's internal archive coding, a faint blue that shimmered under the light. The report title: "Analysis of Subject X's Activity Trajectory (Past Three Years)." The font was standard Song typeface, cold and standardized. His gaze swept quickly over the printed text. "...Activity concentrated in the border area between the old industrial district and the shantytown in the west of the city... Consumption records indicate regular purchases of daily necessities at 'Old Liu's Grocery Store,' categories fixed (cigarettes, instant noodles The behavioral profile in the report overlapped with his memories of Old K's habits with an unnerving, heart-pounding precision. Old K had also preferred disposable phones, had also favored the labyrinthine, seedy shantytown in the west of the city as his operational base, even that "Old Liu's Grocery Store"—Lu Chenzhou remembered, ten years ago, Old K used to buy the cheapest kind of cigarettes there, his fingers stained a deep, burnt yellow. He turned the pages faster, the paper edges scraping against the pad of his thumb with a faint friction, the *rustle* amplified in the silence. The latter part of the report included photocopies of bank statements—the printer ink somewhat faded, but the numbers clear; timeline analyses of surveillance screenshots marked with red and blue lines; even transcriptions of a few audio recordings, the dialogues brief, the wording cryptic. It was terrifyingly professional, exhaustive to the point of being a naked display of arrogance—*Look, I hold everything.* Then, his fingers stopped. It was a photo of a signature page from a confidentiality agreement. The angle was slightly skewed, the lighting poor, as if hastily taken with a phone, but the key information was clearly visible. The agreement title: *Shen Yan Group Peripheral Information Consulting Advisor Engagement Contract*. The Party A stamp was the bright red seal of "Shen Yan Group (Holdings) Co., Ltd." The Party B signature line— He stared at the signature. The cursive arc, the habitual pause at the beginning of a stroke, the upward hook at the end, and that unique, slightly stiff hesitation in the final stroke of the letter 'K'. Ten years ago, when Old K wrote him that informant fee receipt, the signature had been exactly like this. He could trace every stroke from memory with his eyes closed. The contract signing date: November 28, 2013. Lu Chenzhou's prison date was September 15, 2013. This agreement was signed less than three months after he was imprisoned. The date on the paper was like an icy needle, stabbing into his eyeballs. Blood seemed to instantly rush back from his limbs to his heart, squeezing his chest until it felt tight, then was violently pumped toward his brain the next second, bringing a sharp, high-frequency ringing. His ears throbbed with the sound of his own heavy, rapid heartbeat—*thump, thump, thump*—like someone striking his eardrums with a cloth-wrapped mallet. His throat went dry; swallowing became difficult. He released the report, the papers slipping from his fingers, scattering across the desk with a messy *rustle*. The room was left with only the faint *buzz* of the desk lamp's current, like some smoldering threat. Outside the window, a distant car occasionally passed, the sound of tires on asphalt stretched and distorted by distance into a blurry background noise. Lu Chenzhou stood up, his movements somewhat stiff, his knee joints emitting a soft *crack*. He walked to the bed, crouched down, the bed frame groaning under the shift in weight. From under the bed, he dragged out an old military-green metal trunk. The trunk was heavy, its surface paint peeling, revealing mottled rust underneath, rough and cold to the touch. When he opened it, the rusty hinges let out a dull *clang*, and a strong mix of iron rust, the musty smell of old paper, and a faint odor of mothballs surged out, hitting him in the face. Several work notebooks with curled, blackened edges, a stack of case photos yellowed and stuck together at the edges, and a few small pieces of evidence carefully sealed in transparent plastic bags—a button, a section of charred electrical wire, a flattened cigarette pack. His fingertips probed through the clutter, encountering a complex mix of textures: cold metal, rough paper, smooth plastic. Then, at the very bottom, he felt the sharp corner of a hardcover notebook. He pulled it out. The cover was worn black faux leather. Opening it, the inner pages were brittle and yellowed. From between the pages, he extracted a neatly folded, perfectly square piece of paper. He unfolded it. It was a receipt. Written with a blue ballpoint pen, the handwriting was scrawled but the strokes were clear and forceful, pressing deeply into the paper: "Received from Officer Lu, informant fee, five hundred yuan. Old K. 2013.7.12." The edges of the paper had wrinkled marks from being soaked in water and then dried, like traces from a rainy night. Lu Chenzhou held the thin, fragile receipt and returned to the desk. The chair legs scraped against the floor with a grating sound. He placed the receipt next to the photograph of the signed confidentiality agreement page, lining them up side by side under the desk lamp's dim yellow circle of light. One was yellowed, fragile, with rough, fuzzy edges, bearing the weight of a brief, dangerous trust and promise from that damp, rainy night ten years ago. The other was brand new, cold, printed with crisp clarity, proving that the very same person, shortly after Lu Chenzhou was imprisoned and struggling for survival, had calmly signed a contract pledging service to his enemy. Under the light, the two signatures were laid bare. Every curve of a turn, every fluidity of a connecting stroke, every subtle habit of starting and ending a stroke—they matched perfectly. Like imprints pressed from the same mold. The visual impact was more direct, more brutal, than any deduction. Lu Chenzhou's left hand clenched unconsciously, his knuckles turning white. His fingernails dug deep into the soft flesh of his palm, bringing a clear, sharp sting of pain. But the pain felt distant, as if separated by thick, cold glass. His entire focus was locked on those two pieces of paper. His gaze shifted from the signature on the receipt to the date on the agreement, then back from the agreement date to the receipt signature, comparing them repeatedly, as if confirming an unavoidable mathematical equation. Not only had he not died. But after Lu Chenzhou's imprisonment, he had been swiftly, quietly recruited by Shen Moqing, becoming a hidden piece in the other's intelligence network. Ten years. For a full ten years, Lu Chenzhou had believed Old K had died because of him, silenced because of the case he was investigating. That heavy guilt had been like a rusted iron thorn, deeply embedded in the softest part of his heart, pulling with a dull ache with every heartbeat. Every time he thought of the old case, of that blurry, rain-soaked figure at the alley entrance on that rainy night, of this scrawled yet utterly earnest signature on the receipt, that thorn would twist, reminding him: *Someone paid with their life for your persistence. This is a debt you owe.* But now, Shen Moqing used this stack of cold, neat documents to tell him: *That thorn was false. The object of your guilt, the "innocent victim" you were determined to protect, has been alive all along, living hidden but safe, and became a living piece already placed on your enemy's chessboard. Your ten years of heaviness were nothing but a meticulously designed mockery.* The shame of having his protective instincts utterly fooled and trampled poured over him like scalding, viscous asphalt, instantly enveloping his entire body. Scalding, suffocating, carrying a nauseating smell of scorching. His throat tightened violently, and an uncontrollable, rust-like metallic sweetness rose in his mouth—the taste of extreme fury forcibly swallowed, suppressed to corrode at the pit of his stomach before surging back up. He closed his eyes, his jawline taut as a blade's edge. A few seconds later, when he opened them again, the bloodshot veins in his eyes were denser, but all the churning emotions in his gaze had been forcibly suppressed, cold as a frozen lake's surface—smooth, hard, reflecting no light. There was one last piece of paper in the file folder. Placed alone at the very bottom, not stapled, neatly folded in half. Lu Chenzhou picked it up. The paper was ordinary, but its texture felt slightly cool. He unfolded it. A4 paper, laser-printed, the text clear. But in the blank space at the bottom right corner, there was a line of handwritten words. Written in deep blue ink, the pen He leaned back into the chair, the leather emitting a faint creak under the weight. Tilting his head back, the nape of his neck pressed against the cool top edge of the chairback. In his line of sight was the ceiling, blurred by the hazy glow from the desk lamp. His breathing was slow, deep, each inhalation like forcing icy air deep into his lungs, cooling the magma churning within. He could feel the expansion of his chest, the curve of his ribs, and the heavy, slow thudding of his heart behind them. The anger still burned, but it was now encased in layer upon layer of ice, a heavy weight sinking to the pit of his stomach. Shame was like fine needles, pricking at his fingertips and temples, but the pain was transmuted into a sharper focus, concentrated on the coldly gleaming paper before him. The tearing sensation of betrayal still spread through his chest, but new, harder bone-like growth was beginning to form along the fissures — an instinct for survival, a thirst for vengeance, an absolute will to live, to win. He could feel the subtle pressure of that growth, propping up a teetering framework from within. Shen Yanqing was in control of all this, and he reveled in it. The handwritten words seemed to still carry the faint metallic tang of ink and the lingering scent unique to that person — a mix of sandalwood and a cold, clean aftershave — stinging his nerves even through the paper. Three facts, like three red-hot steel nails, searing with heat, were driven one after another into the landscape of his understanding. The terrain of the old case was completely reshaped; what he once thought was the "graveyard of the innocent" had now become the "nest of the traitor." The direction of the investigation had to do a one-eighty — no longer about clearing the names of the dead, but about tracking the living traitor, and using him to tear open a gap in the network of the original frame-up. He picked up his phone, the metal frame cold to the touch. Opening the camera, he took pictures page by page of the documents spread on the desk. The flash fired repeatedly in the silent room, sudden bursts of piercing white light slicing through the gloom like silent lightning, each flash leaving a brief afterimage on his retinas. After the last picture, his fingertip slid across the screen to check, confirming every crucial piece of information was clear and accurate. Then, he gathered the original documents in order, the edges rustling softly as he aligned them, stuffed them back into the bulging kraft paper file folder, and resealed it with several loops of clear tape, the tearing sound of the tape starkly clear in the silence. He stood up, the wooden floor giving a slight creak underfoot. Walking to the bathroom, he turned on the faucet. Cold water gushed out with a rush, hitting the ceramic basin. He bent over, cupping his hands under the stream. Most of the water leaked through his fingers, the remaining icy cold slapping his face hard. The chill instantly penetrated his skin, making his scalp tingle and the hairs on his nape stand on end. Once, twice, thrice. Until his cheeks were numb and senseless from the cold, until his breathing grew short and hot from the shock. He lifted his dripping face, looking into the mirror. The reflection showed red-rimmed eyes, bloodshot veins spreading like spiderwebs from deep within the whites, but the gaze was frighteningly calm, like a frozen lake. Water droplets rolled down his taut jawline, dripping onto the cotton collar of his old T-shirt, quickly spreading into a dark, blurry-edged wet patch. He stared into his own eyes for a long time, until he was certain everything churning within was pressed down to the deepest depths, leaving only a reflective, hard layer of ice on the surface. From the desk drawer, he pulled out a folded city map. The paper edges were slightly curled from long disuse, carrying a faint smell of dust. Spreading it on the desk, he pressed it flat with his hand, found the western district. His fingertip traced the rough printed line of Guangming Road, stopping at the small black square marking No. 127. Picking up a red pen, the tip hovered for a moment before landing, drawing a forceful circle. The red ink seeped slightly into the paper fibers. Then, from the bottom shelf of the bookcase, he retrieved a black hardcover notebook, flipping to a blank page. The paper was pristine white and stiff. He picked up a fountain pen and began writing quickly, the nib scratching across the page with a steady, urgent sound. "Hypothesis 1: Old K's 'death' back then was fabricated. Purpose: to sever my chain of evidence and create conditions for him to go underground and serve Shen Yan." "Hypothesis 2: Shen Yan "1. Must attend the meeting. Absence signifies weakness and will forfeit the only opportunity to access the scene and observe the 'assistant's' reaction." "2. Objective is not to contact K, nor to obtain clues. Primary goal: assess the on-site environment, surveillance layout, and potential for ambush; secondary goal: test Gu Zhixing's (the assistant) role and authority within this setup." "3. Cover for the action: use 'verifying peripheral leads in Zhao Mingcheng's case' as a pretext. Must fabricate a corresponding plan document, with details that can withstand scrutiny." "4. Equipment: micro camera, voice recorder, self-defense spray, portable signal jammer (time-limited), backup phone." "5. Evacuation routes: plan three. Primary route is north on Guangming Road to the subway station; backup one is through the hutment alleys to the bus terminal; backup two is... (to be added after on-site reconnaissance)." His gaze fell on the two characters "Old K." The pen tip hovered for a moment, then he forcefully crossed them out horizontally, the ink almost piercing through the paper. He wrote anew beside it: "Target K (original codename Old K) — a potential information source and high-risk factor requiring cautious contact. Priority: Medium. Handling principle: Do not initiate contact, do not reveal intent. If forced into confrontation, limit to intelligence acquisition; control measures may be taken if necessary." After writing, he closed the notebook, the hardcover making a faint clacking sound. He retrieved a small electric kettle from the corner of the wardrobe, its plastic shell feeling icy to the touch. He filled it with water, pressed the switch, and the heating element began emitting a low hum, with fine bubbles gradually forming at the bottom. While waiting for the water to boil, he walked to the window and lifted a corner of the heavy blackout curtain. The cold touch of the glass transmitted through his fingertips. The street at dawn was empty, streetlights casting pools of dim yellow light, their edges blurred by the damp air. Occasionally, the roar of a late-night motorcycle engine tore through the distance, the sound growing near then swiftly receding, ripping through the stillness. Chilly air seeped in through the window crack, carrying the complex smell unique to a city night—a mixture of dust, faint exhaust fumes, and the distant, faintly sour stench of a garbage heap. The water boiled, and a sharp whistling sound erupted. He unplugged the kettle, steam billowing hot and white from the spout. Opening the tea caddy, he grabbed a large handful of dark green tea leaves and tossed them into the cup. Pouring the boiling water over them, the deep brown tea liquor immediately churned violently. A bitter, intense aroma mixed with steam rose, feeling somewhat scalding against his face. He picked up the thick ceramic cup, blew on the floating tea leaves on the surface, and took a careful sip. The scalding liquid slid over his tongue, leaving a distinct astringency, then burned its way down the esophagus like a faint yet resolute line of fire, temporarily dispelling the bone-deep chill that had taken root. He drank slowly, sip by sip, feeling that bit of heat spread within his icy body until the cup was empty, only soaked tea leaves clinging to the walls. Opening the wardrobe, he took out a clean set of light gray shirt and black trousers. The cotton fabric was ironed to an extreme crispness, feeling slightly stiff to the touch, emitting the faint smell of mothballs from the wardrobe. He removed the old T-shirt he was wearing, damp with cold water, the collar stained, as if still retaining the oppressive, opulent air of the Shen residence. As the fabric peeled away from his skin, it brought a slight, cool shiver. He changed into the clean shirt, buttoning it up one by one. The fabric against his skin, with its slightly rough texture, brought a strange sense of clarity. Then the trousers, the belt buckle snapping shut with a crisp *click*. This was a symbolic "shedding," slight yet tangible. Not victory, not liberation, just a temporary climb out of a psychological quagmire, changing out of old clothes caked in cold mud, grooming himself for the next, even more dangerous mire he had to step into. He stood before the mirror again. The person in the mirror now wore a stiffly pressed shirt, collar tightly closed, eyes like polished obsidian—cold, reflective, showing no extra emotion. All the turbulent things were pressed into the deepest recesses of his eyes, the surface left with only a hard
