Chapter 325: The Redevelopment Zone and the Supplementary Agreement

The alarm was set for 6:40. Lin Chen opened his eyes at 6:35.

A familiar stiffness radiated from his left ankle, like a rusted hinge jammed in the bone. He sat on the edge of the bed, not rising immediately, but slowly flexing his toes until returning blood flow brought a faint sting. On the nightstand sat half a glass of warm water, two ibuprofen tablets, and a list circled in red pen the night before. He swallowed the pills, applied a hot towel to his knee for ten minutes, then got up to wash. The man in the mirror had faint blue shadows under his eyes, but his gaze was calm. He changed into loose trousers and soft-soled sneakers, then checked his backpack: the draft supplementary confirmation letter, a portable ink pad, a black signature pen, a pocket scanner, and Chen Guodong’s contact information. Everything in order. He locked the door and headed downstairs.

The morning streets were empty, the streetlights not yet fully extinguished. He settled into the driver’s seat, adjusted the angle, and placed his left foot flat on the floor mat to avoid prolonged dangling that would compress the nerves. The navigation system showed a twenty-five-minute drive from the company to the West City Textile Factory Family Quarters under normal conditions. But the side roads in the redevelopment zone would begin traffic restrictions before the morning rush. He had to pass through the construction barriers before 7:50.

The car merged onto the ring road as the sky shifted from dark to gray. Under the overpass, breakfast stalls were already steaming. Youtiao swelled in boiling oil, and the cloying sweetness of fried pastries mixed with diesel exhaust drifted through the window. Lin Chen did not stop. He turned on the car Bluetooth and played a track of white noise to drown out the static in his mind. The forty-eight-hour countdown ticked slowly in his head, but every step was firmly planted on solid ground.

At 7:42, the navigation chimed: “Road construction ahead. Please slow down.” The asphalt gave way to compacted gravel, flanked by blue corrugated iron hoarding printed with faded “Urban Renewal” slogans. He parked in a temporary space outside the barriers, killed the engine, and grabbed his document bag.

A three-hundred-meter walk. The gravel was uneven; each time his left foot landed, he had to rely on his right leg to share the weight. His gait was slightly uneven, but the rhythm was steady. Only half of the family quarters’ main gate remained. The guardhouse window had a crack running through it, and the room inside was empty. He passed through the gateway, followed the information Old Zhou had provided, and located Building 4, Unit 2. The stairwell reeked of decades-old dampness and the lingering sulfur of coal briquette stoves. Paint peeled from the walls, exposing the red brick beneath. The motion-sensor light was dead. He switched on his phone’s flashlight and climbed the stairs.

Third floor. Room 201.

He raised his hand and knocked. Three times. A pause. Three more times.

The sound of slippers shuffling against the floor came from inside, followed by the click of a turning lock. The door opened a crack, revealing half a face mottled with age spots. His hair was gray, he wore reading glasses, and he was dressed in a faded gray jacket.

“Are you Director Chen Guodong?” Lin Chen kept his voice low, his tone steady.

The old man studied him for two seconds, his eyes wary. “I am. Who are you looking for?”

“An old colleague from the Provincial Hospital’s IT department asked me to visit. My name is Lin Chen. I’m currently handling data compliance tracing for the 2016 server room relocation project.” Lin Chen offered a business card but did not step over the threshold. “Sorry to disturb your rest. I’m here to request a supplementary confirmation letter for historical operations. It carries no liability implications. It’s simply that the new Health Commission system requires a complete archival chain. I’ve already drafted the materials according to the template; you just need to review them.”

Chen Guodong did not take the card. He stepped aside half a pace. “Come in. It’s windy out there.”

The apartment was small, furnished with pieces from the nineties. On the coffee table sat medicine boxes and half a cup of cold tea. Chen Guodong sat on the sofa and rubbed his knee. “Old Zhou told you? I retired years ago. The system has been replaced three times over. Why dig up old accounts?”

“It’s not digging up old accounts. It’s completing procedures.” Lin Chen sat in the chair opposite him, maintaining an arm’s length of distance, and pulled the confirmation letter from his bag. “The relocation contract from November 5, 2016, lacks a review stamp in the Party A signature column. The Health Commission’s audit template requires a dual-person closed loop. As the IT Director at the time, you only need to confirm that ‘this relocation was a collective departmental decision, and the data migration process was executed according to the regulations in effect at the time.’ It does not involve liability tracing, nor will it affect your current retirement benefits. It’s merely a formality to complete the historical archives.”

Chen Guodong put on his reading glasses and took the paper. He read slowly, his fingers tracing the surface. He paused at the words “Historical Operation Confirmation.” “What does ‘the operator and reviewer jointly bear archival obligations’ mean?”

“Template boilerplate.” Lin Chen immediately took out his pen, crossed out the line, and rewrote it in the blank margin. “I’ll change it to: ‘This letter serves solely to certify that the November 2016 server room relocation project completed data migration and physical sealing in accordance with hospital procedures at the time, and shall not be used as a basis for subsequent liability determination.’ Does that work for you?”

Chen Guodong looked up, the wariness in his eyes softening. “You’ve thought this through clearly.”

“In compliance work, you have to nail down the wording but leave the path open.” Lin Chen’s tone was flat. “Just sign it and press your fingerprint. I’ll make a photocopy of the front and back of your ID to attach. It can be submitted today, and no one will bother you with this again.”

The room fell quiet for a few seconds. Only the ticking of an old wall clock filled the space. Chen Guodong sighed, rummaged through the coffee table drawer, and pulled out a fountain pen. The cap was slightly rusted. He twisted it open and signed his name on the paper. The handwriting lacked the force of his younger years, but the structure remained. When he finished, he extended his right index finger. Lin Chen opened the ink pad and handed it over. The old man pressed down, lifted his finger, and left a clear red fingerprint on the page.

“The ID is in the cabinet in the inner room.” Chen Guodong stood up, his movements slow. “Let my wife find it.”

Lin Chen nodded. He looked at the signed letter; the paper lay flat, the ink still wet. He took out his pocket scanner, laid the document on the coffee table, and pressed the scan button. The machine emitted a soft hum, and a green light flashed. Three minutes later, the PDF was generated. He checked it once: clarity met the standard, all required elements were present.

Chen Guodong’s wife handed over the photocopy of the ID. Lin Chen accepted it with both hands and thanked her. He did not linger, rising to take his leave.

“Xiao Lin,” Chen Guodong called out at the door. “What you’re doing now isn’t easy. Back in our day, getting it to work was enough. Who cared about data lineage?”

“Times have changed.” Lin Chen turned back. “Before, it just had to function. Now, you have to be able to explain exactly where it came from and where it’s going. The foundation you laid back then was solid, which is why supplementing it now is so straightforward.”

The old man waved a hand and said nothing more.

Lin Chen went downstairs and exited the family quarters. The time was 8:20. Ten minutes ahead of schedule. He walked briskly back to his car, opened the door, and placed the document bag and the scanned USB drive into the shockproof compartment of his case. He started the engine and drove toward the Data Authentication Center at the Municipal Quality Inspection Institute.

Morning rush hour traffic began to converge. At a red light, he lightly pressed the brake, and a dull ache shot through his left foot. He adjusted his posture, shifting his weight to the right. His phone screen lit up with a message from Su Man: The authentication center schedule has been updated. The preliminary report for today’s sample batch will be out at 4 PM. How’s it going on your end?

Lin Chen replied: Supplementary letter obtained. En route. Expected arrival before 9.

The car entered the institute’s campus. The underground garage was empty. He parked, carried the turnover box and document bag to the reception window on the first floor. The staff verified the checklist, inspected the media seal labels, and scanned the supplementary letter. The process was strictly standard, with no unnecessary words.

“Materials are complete. Acceptance number is CMA-20241108-047.” The staff member handed him a receipt. “Report issuance time: Tomorrow at 16:00. For overdue inquiries, please present this receipt.”

Lin Chen took the receipt and signed. He turned and walked out of the lobby. The sunlight was glaring; he squinted and got back into his car.

Seventy-two hours. Thirty-nine remaining. The chain was closed, missing only the final link.

Just as he fastened his seatbelt, his phone vibrated. It wasn’t Su Man. It was an automated push notification from the Provincial Health Commission’s Science and Technology Department system.

[Pre-Review Notice] Your submitted archival materials have entered the cross-comparison queue. The system has detected a historical overlap between the IP allocation segment (10.128.4.0/24) in the 2016 migration log and the currently registered network segment. Please supplement the following by 17:00 today: the original network topology diagram and the IP allocation quota approval form. Failure to comply will trigger a Level-2 manual review.

Lin Chen stared at the screen. His fingers hovered over the touchpad for two seconds.

He opened his logbook, turned to a fresh page, and wrote: IP segment overlap. Need to retrieve 2016 network topology diagram. Approval form located in the hospital office archive room. Time window: Before 17:00 today.

He closed the book and started the car. The engine hummed low as he drove out of the campus. In the rearview mirror, the authentication center building gradually receded. He did not accelerate. He simply gripped the steering wheel, his gaze fixed on the lane stretching out ahead.

Dust settled in the shafts of light. The countdown continued.
