Chapter 111: Compressed Margin

The ledger lay open on the upper right corner of the desk. Lin Chen used a pencil to cross out “10:30” and wrote “10:25” in its place. Handing in the paper five minutes early bought him five minutes. But those five minutes didn’t materialize out of thin air; they meant compressing the derivation steps for the last two major questions in the comprehensive science exam, skipping double-checks on the multiple-choice section, and filling out the answer sheet in a single, unbroken pass. He had to finish bubbling in the answer sheet before the submission bell rang, with no time to look back.

1.2 kilometers, 15 minutes. A pace of 80 meters per minute. His left foot was numb, his center of gravity tilting to the right. He took off his shoe and wrapped his ankle with two extra turns of bandage to stabilize the loose joint. The edges of the gauze had already yellowed, the dried exudate from tissue fluid forming a hard crust. He slipped a layer of cut cardboard into his shoe to reduce friction against the sole. The load-bearing area, coefficient of friction, and angle of center-of-gravity shift for each step ran through his mind. This wasn’t walking; it was mechanical transmission. The tolerance still held, but the dial had just ticked back one notch.

During Tuesday’s evening study session, he didn’t grind through practice problems. Instead, he silently rehearsed the verification checklist. Was the zipper on the document bag smooth? Were his ID card and student ID stored separately to prevent loss? Had he taped the corners of the application form signed by Old Chen to protect it from rain? He checked it three times. Lights out at eleven. The dormitory filled with snores. He lay flat on his back, keeping his left foot suspended to avoid pressure. His breathing was steady, his heart rate locked at resting levels. He knew tomorrow wasn’t an exam; it was a contract to be fulfilled. Old Chen’s words still echoed in his ears: The school won’t catch you if you fall. You walk it yourself.

Wednesday morning, the first mock exam. The comprehensive science papers were distributed. For the multiple-choice questions, he no longer double-checked. For the physics problems, he wrote down the core formulas directly, skipping intermediate derivations. For the chemistry experiment questions, he only noted the key steps and observations. Time fell like sand through an hourglass, steady and unrelenting. At 10:22, he finished bubbling in the answer sheet for the final biology question. He checked the alignment once—no misplacements. At 10:25, he raised his hand to submit. The invigilator glanced at him but said nothing. He stood up. His left foot hit the floor, the numbness feeling like a layer of thick rubber. He adjusted his stride and walked out of the exam room.

From the corridor to the school gate: 300 meters. He stepped out at 10:27. The wind on the old county road was harsher than on the provincial highway, whipping yellow dust against his face. 1.2 kilometers. He had to cover it in 13 minutes. The first 400 meters were flat, his pace steady. The remaining 800 meters were a downhill slope merging into a gravel path; he had to lean his weight forward, or his left foot would slip. He clenched his teeth, his breathing growing heavy. Sweat trickled from his temples into his eyes, stinging. At 10:40, he reached the ticket window at the bus station. He handed over the money and bought his ticket. The bus was already running, the air thick with the smell of diesel and sweat. He squeezed into the very back row and took a window seat.

The bus pulled onto the old county road. The conditions were worse than he’d anticipated. Potholes, speed bumps, sudden brakes for oncoming traffic. Every jolt scraped the nerves in his left foot like a dull knife. He closed his eyes, counting the time in his head. 11:15. 11:45. 12:20. The timestamps from his ledger pulsed in his mind. At 13:05, the bus pulled into the provincial city’s bus terminal. Ten minutes behind schedule. The traffic control on the old county road wasn’t one-way; it was alternating two-way passage. He had miscalculated the dispatcher’s on-the-spot adjustments. A detour that should have taken 45 minutes had been stretched to 55 by the actual road conditions.

At 13:15, he got off. His left foot had completely lost sensation; he could only drag it forward using his thigh muscles. He transferred to a city bus, dropping coins, swiping his card. At 13:40, he reached the South Gate of the Provincial Institute of Technology. Thirty-five minutes remained until the verification deadline. He walked into the administrative building lobby. The queue already stretched to the foot of the stairs. He pulled out his document bag. The zipper jammed. He yanked it hard, and the pull tab snapped off. The materials scattered across the floor. Eyes turned toward him. He squatted down. His fingers trembled, but his movements didn’t stop. He picked everything up in order, slid it into a plastic bag, and secured it with paper clips. At 13:55, he reached the verification window. The staff member looked up: “ID card, admission ticket, deferred exam certificate, design statement.” He handed them over. The staff member flipped to the deferred exam form and frowned. “The homeroom teacher’s signature column. The ink is smudged. I can’t make out the date.” Lin Chen’s heart skipped a beat. He looked at the form. Old Chen’s signature was indeed slightly blurred by sweat. He spoke quietly, “It was signed this morning. You can verify it against the school seal.” The staff member said nothing, picking up the phone. “Hello, Admissions Office? We have a deferred exam form here with a smudged signature…” Lin Chen stood perfectly still, the center of gravity in his left foot shifting slightly. He knew the final variable wasn’t the road. It was people.
