Two words and a question mark. The cold needle tip pierced the membrane of delay. Lu Chenzhou stared at the screen, his fingertips hovering motionless above the keyboard. The red dot outside the window was still there. The outline of that silver sedan at the street corner, in the darkness of 3:30 a.m., resembled a silent tombstone. They knew. Not only were they watching the residence, watching that car. They might be watching this computer. Not physical screen peeping, but something more foundational—process monitoring, network traffic analysis, callback signals triggered by decryption tools. They might have even planted something on the network equipment at this temporary hideout of his long ago. They were monitoring the "decision point in time." They knew what was on the USB drive, had calculated when he "should" have discovered the crucial content, and estimated the possible reactions he might have after "uncovering the truth" along with the corresponding time windows. Was this email a reminder sent after he had "overstayed" without submitting any report, or was it an inquiry triggered after he took "abnormal" action—that late-night prepaid call to Shen Qinghuan? Lu Chenzhou's Adam's apple bobbed. The sound of swallowing, in the excessively quiet room, was piercingly clear. He closed the email interface without replying. His fingertips tapped on the keyboard, continuing to complete that "technical analysis brief" for Gu Zhixing. The wording was bland, details piled up, conclusions vague. A standard, bureaucratic document used to deal with superiors and buy time. He typed the final period, saved, encrypted, dragged it into the scheduled send queue, and set it to be sent automatically three hours later. The room was left with only the faint blue glow of the phone screen and the sound of his own breathing. Blood pulsed in his eardrums, like distant, muffled tides. He sat in the darkness, spine straight, the corner of his left eye beginning to twitch uncontrollably. His fingers unconsciously found a ballpoint pen on the table, his fingertip pressing against the cap, twisting, disassembling, the spring popping out, only to be precisely pressed back and reassembled by him. The metal parts made faint clicking sounds in his palm. He was waiting. Waiting for the chain reaction, waiting for the person who might step out of that car outside the window, waiting for Gu Zhixing or Shen Moqing's next instruction. Time dripped like viscous syrup. It wasn't the email notification sound; it was an incoming call. The screen lit up, displaying a string of unremarked numbers he had long since memorized—Shen Moqing's private mobile phone. Lu Chenzhou watched the string of numbers vibrate in his palm. The vibration crawled up along his finger bones. Three seconds later, he pressed answer, saying nothing. Shen Moqing's steady, mild voice came through the receiver, without pleasantries or prelude. "Jingyuan, come to the study. There are some old things you should perhaps see." Lu Chenzhou put down the phone. Outside the window, the headlights of the silver sedan at the street corner silently lit up. *** Shen Moqing's main residence study always exuded a mixed scent: the clear, lingering after-aroma of expensive sandalwood incense, and the slightly damp, musty smell emitted by old books and aged document paper. The two scents intertwined, settling into every inch of the air. When Lu Chenzhou entered, Shen Moqing was standing behind the massive rosewood desk, his back to him, gazing out the window at the sky not yet fully bright. The old man wore a dark gray Chinese-style jacket, his posture erect. The jade thumb ring on his left hand glowed with a warm green hue in the faint morning light. Lu Chenzhou stopped three paces in front of the desk, standing still. His gaze swept over the desktop—no tea, no documents, only a thick kraft paper envelope lying quietly on the smooth wood grain. The envelope was sealed with an old-fashioned wax seal, deep red, the pattern blurred, but it had already been opened. The cracked edges of the wax were jagged, as if someone had carefully pried it open with a paper knife. Shen Moqing finally turned around. His face was expressionless, his gaze like two ancient wells of unfathomable depth, falling upon Lu Chenzhou. He extended his right hand, his fingertip lightly tapping the kraft paper envelope, then slowly pushed it across the desk, stopping in front of Lu Chenzhou. The envelope rubbed against the wooden desk, making a rough, dry rustling sound. Lu Chenzhou did not immediately pick it up. His gaze shifted from the envelope to Shen Moqing's face, then back to the envelope. His Adam's apple bobbed again; the act of swallowing, amplified in the excessively Shen Moqing's fingertips lightly tapped once on the desktop. It was very light, almost inaudible. His tone was gentle, his diction refined. "Sun Mingyuan, the secretary of the deceased founding member of the group. His complete personnel file, and..." He paused, his gaze falling on the paper bag, "...copies of some old documents he handled that might interest you." He raised his eyes and looked at Lu Chenzhou. In those ancient well-like eyes, a faint, almost playful glimmer finally flashed. "Jingyuan, see what you can find in there." Lu Chenzhou's fingers tightened. The rough surface of the kraft paper rubbed against his fingertips. He didn't say "thank you," nor did he make any gesture, he merely gave a slight nod. Then, right in front of Shen Moqing, he began to open the already loose seal of the paper bag. His movements were slow. His fingertips pried open the folded edge of the kraft paper, probed inside, touching the cool, smooth surface of the documents within. He pulled out a stack, about one-third of the thickness, and placed it on the desk. He didn't sit down, just stood there, leaning forward slightly, and began to flip through them. His gaze was like a scanner. Skimming over the titles, dates, numbers, and signature fields at the top of the pages. His brain operated at high speed under immense pressure, cross-referencing every node in the timeline of the old case stored in his memory, every known piece of information about Sun Mingyuan—that former secretary who had long since died of illness, who played a key handling role in the evidence chain of the old case. The paper quality of the copied documents was good, but aged, the edges slightly yellowed. The printed font reflected subtle, almost imperceptible glints under the soft light of the study. His fingertips brushed across the paper's surface, the touch cold. In the air, the complex scent of agarwood mixed with mildew stirred with the motion of his turning pages. The first document was Sun Mingyuan's personnel onboarding form. The date was over twenty years ago. The man in the photo was young, serious, wearing black-framed glasses. The second was his annual performance reviews over the years, with standard, unremarkable comments. The third was a record of position transfers... Lu Chenzhou flipped through page after page, his pace steady, his gaze focused, without any superfluous expression. Shen Moqing turned back toward the window, his back to him. The jade thumb ring on his left thumb began to rotate slowly, rhythmically. The friction between the jade and skin produced an almost inaudible, subtle sound. The pause lasted only about half a second. But in this study where a pin drop could be heard, in front of this elder whose back was turned yet seemed to sense his every reaction with every pore, this half-second pause weighed heavily. It was an "Employee Resignation Approval Form." Applicant: Sun Mingyuan. Application Date: Three months before the old case occurred. The approval opinion section bore a bright red "Approved" stamp, signed by the Human Resources Director at the time—a name Lu Chenzhou vaguely remembered, someone later transferred from their position due to economic issues. He maintained his page-flipping posture, but his gaze had already jumped to the latter part of the stack in his hand. His fingertips rapidly flipped through, the papers rustling softly. A few seconds later, he pulled out another document. "Evidence Storage Registration Form (Number: CZ-201X-XXX)." Date Field: One month before the old case occurred. The Evidence Name field was a string of codes. The Receiver field had a clear, personal seal-stamped signature: Sun Mingyuan. In the lower right corner of the form, there was a line of small-print notes: "Handler confirms evidence chain is complete, sealed for storage." Lu Chenzhou's breath caught in that instant. A sharp ringing filled his ears, like blood rushing to his head. The dates on the two documents in front of him collided and echoed in his mind. Three months before resignation. One month before evidence storage. In theory, a former secretary who had already formally resigned, with all procedures completed, could not possibly handle the evidence sealing process for a core case. This was a procedural dead end. Unless the process itself was flawed. Or, this resignation approval form was backdated. Or, this storage registration form was forged. Or perhaps—this was a "contradiction" Shen Moqing had placed here for him to see on purpose. A test, bait, a gauge to measure his observational skills, judgment, and loyalty. The twitch at the corner of his left eye became more pronounced. His fingertips unconsciously tightened, almost crumpling the papers in his hand. But he immediately loosened his grip, placed the two documents side-by-side on the desktop, raised his head, Lu Chenzhou’s gaze fell upon the two documents lying side by side. His tone was measured, his logic clear. “If Secretary Sun had officially resigned three months before the old case occurred, theoretically, he should not have been involved in the core evidence filing process a month later. That’s basic procedure.” He paused, then tossed the question back like a boomerang. “Is there an error in the file records, or was there a special procedure in place at the time?” Only the gradually brightening dawn light from outside the window silently spilled over the grain of the rosewood, creeping across the rough surface of the kraft paper envelope. Shen Moqing finally turned around completely. His face remained expressionless, but those ancient-well-like eyes now clearly reflected Lu Chenzhou’s figure. He walked behind the desk, sat down, folded his hands on the desktop. The jade thumb ring glimmered with a dark green light in the morning glow. “Files are dead; people are living.” He spoke slowly, his tone flat, betraying neither joy nor anger. “Records may have errors. Procedures may have exceptions. Or perhaps…” He paused, his gaze settling on Lu Chenzhou’s face as if weighing something. “Someone wanted them to ‘not match up.’” Shen Moqing offered no explanation, no admission, no denial. He merely presented three possibilities, then lightly tossed the right of judgment back to Lu Chenzhou. This was a more sophisticated form of manipulation—I give you the tools, but not the answer; I give you the contradictions, but not the truth. You choose, you guess, you walk into the maze of thought I’ve drawn for you. “The files are yours,” Shen Moqing continued, tapping the kraft paper envelope once more with his fingertip, his tone carrying a blandness that bordered on benevolence. “The truth is for you to judge, Jingyuan.” He leaned back in his chair, his gaze shifting to the window, no longer looking at Lu Chenzhou. His posture was relaxed, yet every subtle movement declared: this brief meeting is over. You should take the ‘gift’ I’ve given you and leave. Lu Chenzhou stood where he was, silent for two seconds. Then he reached out, carefully gathered the scattered documents on the desktop, stacked them in order, and slid them back into the kraft paper envelope. His movements were slow, steady; his fingertips did not tremble. He sealed the envelope, lifted it with both hands, the weight heavy in his palms. “I understand,” he said. His voice remained steady, betraying no emotion. He gave a slight bow, turned, and walked toward the study door. His steps were steady, his back straight, but the muscles of his back tightened imperceptibly the moment he left the study, escaping Shen Moqing’s line of sight. Each step fell on the thick carpet, soundless, yet he could almost hear the echo of his own heartbeat pounding in his chest. A twitch started at the corner of Lu Chenzhou’s left eye. Subtle, uncontrollable. He took a deep breath, forcing the muscles to relax. Outside the car window, the halos of streetlights connected into a dim yellow line. Occasionally, a night-shift taxi roared past, its taillights dragging brief red trails on the damp road. The temporary residence was exposed. He couldn’t return to the Red Brick Building safe house either. His mind rapidly filtered through backup locations: the old residential complex in the east of the city, with high tenant turnover and property management practically non-existent; the short-term rental apartment in the south, registered under a false identity, but only a week’s rent was prepaid, and it might have already expired. Deep in an alley, there was a 24-hour convenience store. Two of the LED tubes on its sign were broken, leaving only half of the character for ‘convenience.’ Several dust-covered electric scooters were parked outside the entrance. He parked the car at the mouth of the alley, picked up the paper bag, and pushed the door open to get out. The convenience store’s glass door slid open automatically. A wave of warm air and the smell of instant noodles hit him. Behind the cash register, a young clerk wearing earphones was looking down at his phone, scrolling, not even glancing up. Lu Chenzhou walked to the innermost shelf, picked up two bottles of mineral water, a pack of compressed biscuits, and the cheapest pack of tissues. When paying, he added an extra fifty yuan. “The back warehouse,” he said, his voice very low. “Let me use it for two hours. Quiet. Uninterrupted.” The clerk finally looked up, sized him up for two seconds, his gaze falling on the kraft paper bag in Lu Chenzhou’s hand, then flicking to the weariness on his face. Then he shrugged, fished a key from a drawer, and The sound of paper rubbing against paper was particularly clear in the silence. He first laid out all the documents in order by page number, his movements slow, his fingertips feeling the thickness and texture of each sheet. Most were photocopies, the edges of the paper slightly curled from repeated handling. A few were printed from scans, with uneven toner and slight blurring around the edges of some characters. Sun Mingyuan — the late senior secretary of the Shen Yan Group. The file began with his employment in 1985: annual evaluation forms, position transfer records, commendations and disciplinary actions... dense tables and stamps. Lu Chenzhou’s gaze swept over each date, each signature like a probe. 1998: Sun Mingyuan transferred from the Administration Department to the CEO’s office, appointed as confidential secretary. 2003: Awarded "Outstanding Employee" of the group. Behind the bonus record was attached a group photo — Shen Yanqing personally presenting the award, Sun Mingyuan slightly bowing, accepting the certificate with both hands. The photo was black and white, rendered even blurrier by photocopying, but the smile on Sun Mingyuan’s face was standard, the curve of his mouth as if measured with a ruler. 2009: An additional line appeared in the job description: "Responsible for drafting and archiving certain external liaison documents." He continued flipping. March 2010, an internal notice: Sun Mingyuan applied for early resignation due to "health reasons," approved. The resignation approval form bore Shen Yanqing’s signature, sweeping and vigorous, the ink forceful enough to penetrate the paper. In the lower right corner of the form, a small handwritten note: "All handled work has been fully transferred, no outstanding issues." Lu Chenzhou’s breathing grew lighter. He pulled another document from the file — the "Cooperation Project Material Transfer Registration Form" between the Shen Yan Group and a certain municipal bureau department. Date: April 12, 2010. The transfer items column listed seven or eight entries. The third item was: "Evidence Custody Box (No. CZ-201004-003) and related ancillary documents." In the recipient column, the three characters "Sun Mingyuan" were starkly written. The handwriting was neat, in blue ballpoint pen. Beside it was a personal seal stamp, the paste red, smudged in places due to the photocopying. But the date was clear: April 12, 2010. Sun Mingyuan resigned in March. In April, under what identity did he sign for this "evidence"-related transfer document? Group rehire? Temporary help? Or was the resignation approval merely a facade, and he had never truly left Shen Yanqing’s inner circle? Lu Chenzhou’s fingertips felt cold. He picked up a red pen and drew a timeline on the sticky note he carried with him. March resignation, April evidence receipt, May... He flipped to the last few pages of the file. They were scattered photocopies of "work logs." The paper was older, the edges bearing traces of water stains. The records were brief, like memos jotted down casually: "April 15, 3 p.m., Attorney Gu visited, assigned special document processing matter. Requirement: Imitate original handwriting, requiring seventy percent similarity in form, thirty percent difference in spirit. Deadline: three days." "April 18, document completed. Attorney Gu inspected, expressed satisfaction. Reminded to destroy drafts and practice sheets. Executed." "April 20, received additional remuneration, cash. Note: This matter not to be entered into any formal record." Lu Chenzhou stared at the line "imitate original handwriting, requiring seventy percent similarity in form, thirty percent difference in spirit." The blood seemed to roar in his ears. He had seen that handwriting — on the "confession" that had nailed him ten years ago. The signature was his, every turn, every pause similar, but subtle tremors in certain connecting strokes betrayed a stiffness born of deliberate imitation. During the trial back then, the defense lawyer had applied for a handwriting appraisal. The appraisal report conclusion read: "Highly consistent with sample handwriting in macroscopic characteristics, but differences exist in some microscopic pen pressure and stroke initiation/termination details, possibly due to different writing states." — An ambiguous conclusion, easily explained by the prosecution as "natural fluctuation due to the defendant writing under immense pressure." "Seventy percent similarity in form" was enough to fool a routine appraisal. "Thirty percent difference in spirit" was the forger’s intentionally left "signature," belonging to himself. Like a painter leaving a hidden mark in the corner of a forgery, understood only by connoisseurs. Lu Chenzhou’s left hand began unconsciously disassembling the red pen in his grasp. Cap, barrel, spring, refill... Parts scattered across the desk, emitting faint sounds. He stared at those components, but his mind was rapidly piecing together another scene: Sun Mingyuan Thus, Sun Mingyuan’s role in the evidence chain of the old case became clear: he was not merely a handler, but the executor of the key forgery link. His signature on the evidence transfer registration form meant he knew what those “pieces of evidence” were, where they came from, and where they were going. He might have even participated in the “processing” and “packaging” of the evidence. From forging handwriting, to packaging the evidence chain, to finally pushing the judicial process forward. Sun Mingyuan was a link in that chain, and a technically core one at that. If he were alive, he might have implicated more people. But he was dead—attached to the file was a copy of a brief obituary: Sun Mingyuan died in 2012 from a “sudden heart attack” at the age of fifty-two. The memorial service was very small, attended only by relatives and a few old colleagues. Lu Chenzhou felt a surge of icy excitement, like swallowing a mouthful of ice shards in deep winter, cutting all the way from his throat to the pit of his stomach. He had found a key node. This node could connect the handwriting clue, the material evidence chain, and even Shen Yanqing’s motive. But at the same time, a deeper chill crawled up his spine. Shen Yanqing knew he knew. Shen Yanqing had deliberately let him see these things. Why? To test his reaction? To see if he would immediately jump up, take this “evidence” and go confront, retaliate? Or was this itself part of the trap—letting him think he had found a breakthrough, while actually guiding him toward a deeper snare? He put down the pen, fingers pressing against his temples. His head ached. The air in the warehouse was stale, carrying the smell of rust and dust. The energy-saving lamp emitted a low hum. He picked up the file again and flipped to the end. At the bottom of the kraft paper envelope, there was indeed a photograph. Not a copy, but an original old photo, very small, its edges already white and curled. He pinched a corner of the photo and held it up to the light. The photo showed three people. The background seemed to be a private courtyard, with the outlines of a rockery and pine trees. On the left was a young Shen Yanqing, wearing a Zhongshan suit, smiling. On the right was Sun Mingyuan, looking younger than in his file photo, standing straight, his expression respectful. The person standing in the middle— Lu Chenzhou’s breath caught. The person in the middle wore an ordinary jacket, his face gentle, the corners of his mouth carrying a faint, barely-there smile. One of his hands rested casually on Sun Mingyuan’s shoulder, his posture relaxed, like a close elder or friend. It was Gu Zhixing. Gu Zhixing from ten years ago. His hair darker, his wrinkles fewer, but the unique quality in his eyes—that blend of gentleness and sharpness—was exactly the same. On the back of the photo, a line of small characters was written in fountain pen, the handwriting elegant and delicate, not Sun Mingyuan’s: “Spring 1999, at the East Courtyard of the Shen Residence. For remembrance.” 1999. The second year after Sun Mingyuan was transferred to the CEO’s office. Gu Zhixing was not yet the group’s chief legal counsel, but he was clearly already a frequent visitor to the Shen residence, someone who could stand shoulder-to-shoulder with Shen Yanqing and place a hand on the shoulder of the confidential secretary. Lu Chenzhou stared at Gu Zhixing’s hand resting on Sun Mingyuan’s shoulder in the photo. That hand was steady, the fingers slender. It was this same hand that later drafted countless legal documents, designed the precise evidence chain, and sent Lu Chenzhou to prison. And it was this same hand that was now pulling him back into this web, email by email, instruction by instruction. He placed the photo gently on the desk. His fingertips were cold. Shen Yanqing was right. He would indeed want to see this photo. It proved nothing, and yet it proved everything. It turned Sun Mingyuan from a vague name in a file into a living person—a person who stood between Shen Yanqing and Gu Zhixing, smiling for a commemorative photo. A person who, even after “leaving his post,” could still forge handwriting for them, sign for evidence. A person who, after completing all his tasks, died from a “sudden heart attack.” Lu Chenzhou leaned back in his chair and closed his eyes. The silence of the warehouse pressed down, heavy with dust. He was not searching for the truth. He was walking onto a stage that had long been prepared for him. Shen Yanqing had given him the first page of the script. Gu Zhixing was manipulating the lights and sound He straightened his posture and began carefully gathering all the documents, placing them back into the manila envelope. His movements were slow, deliberate, ensuring the order of every page remained exactly as before. Finally, he slipped that old photograph into the middle of the file and sealed the envelope's flap. Then, he took the prepaid phone from his pocket, powered it on, and opened the encrypted messaging app. Only one avatar in the list was lit up—Qin Wangshu. He typed a message, his fingers steady, without hesitation: "Back when my house was burgled, who was the one who ultimately filed the final report into the archive?" Send. The screen displayed "Delivered."
