Chapter 22: The Silent Trigger

4:17 a.m.

Dong Lan’s fingers, poised over the keyboard, suddenly froze.

On the screen of the provincial bureau’s technical department, scarlet alarms flickered—“Unusual Access to Jiangcheng Police Internal Network”—the alert tone was as sharp as a needle, piercing precisely into the nape of her neck. Its short, high-frequency metallic chill bounced endlessly through the silent command center.

She instinctively hunched her shoulders, fingertips brushing the chilled plastic edge of the keyboard, as if she were touching some living, dangerous thing.

She pulled the jacket draped over her chair around her shoulders; the fabric rasped softly against her neck, carrying the faint, bitter scent of yesterday’s coffee stains.

Her mouse clicked the tracking module so quickly it seemed to cut the air—the access path on the screen drew a silver line across the electronic map, slicing through darkness like a scalpel, finally pinning itself to the coordinates: “Zhou Mingyuan Private Legal Advisor’s Office.”

“They’ve taken the bait.” Her first words to her phone came out with a sandpaper rasp, her throat still rough from being jolted awake.

On the other end, Lu Yuan was clearly sleepless too. The background was filled with rapid, orderly keystrokes, like rain striking a tin roof. “I’m pulling the lawyer’s financial transactions now. Last month, Zhou Mingyuan’s cousin’s real estate company sent a fifty-thousand consultation fee.”

Dong Lan stared at the ever-refreshing access logs, her knuckles pressed to her philtrum, a faint sting running along the edge of her nails.

A memory flashed in: three years ago, she’d brought Song Zhao to the national forensics competition—he was crouched in the lab, labeling evidence under the shadowless lamp, reading glasses perched on his nose, fingertips sticky with glue, labels fluttering between his fingers like butterfly wings.

He’d said then, “Sister Dong, the best trap isn’t hidden—it’s when the prey thinks it’s searching.” Now, it seemed the boy had carved that into his bones—Su Wan’s code buried in the “Jiangcheng Water Conservancy Chronicles” had finally hooked its fish.

“Cross-reference the transaction flows and access logs,” she said, sipping cold tea from her thermos. As the tea slid down her throat, it left a metallic tang, her tongue bitter. “Flag repeated transfers.” Before she finished, the printer suddenly spat out a stack of paper—the top sheet was a screenshot of the internal network’s operation log. The timestamp—23:47:16—gleamed coldly; the toner still wet, a touch left a gray smudge.

At the same moment, beneath Zhaoyang Bridge, rain was streaming from Chen Mo’s cap into his police collar, icy water tracing his spine and sending shivers through him.

He had been standing by the bridge for forty minutes, the heels of his dress shoes sunk into mud, soles scraping wet earth with a squelch, like a softened wooden stake battered by wind and rain.

When his phone vibrated for the third time, he instinctively gripped it tight—the unsigned text on the screen was jarringly clear: “The log you deleted has been restored. Dashcam evidence is public. Zhou will silence you.” The cold glow of the screen flashed like a blade in his pupil.

With a heavy thud, his fingers pressed against the bridge rail. The rusted iron felt rough, red-brown powder wedged under his nails.

Three years ago, that rainy night replayed in a flash: Song Zhao was struck and sent flying, while Chen Mo was twenty meters away in the guard booth, frantically smearing correction fluid across the duty log—the fumes stung his eyes, the sharp solvent scent blasting his nose like chemicals poured into his lungs.

Zhou Mingyuan’s secretary had patted his shoulder then: “Little Chen, your master’s case has been closed for ten years. If Old Song knew his precious son risked his life for some cold case…” He couldn’t remember the rest, only the thunder of rain on the booth’s tin roof, beating like a drum, making his temples throb.

Distant headlights sliced through the rain; Chen Mo straightened abruptly, his muscles stiff from standing, his knees cracking softly.

As the black sedan emerged under the bridge, he stumbled after it, muddy droplets flicking from his uniform hem onto his pant legs, leaving scattered wet marks.

The phone camera blurred in the rain, but the snapped license plate froze his blood—that was Zhou Mingyuan’s backup car, registered under his personal driver. Chen Mo had helped handle a traffic violation for it last year.

Rainwater gleamed on the plate’s edge like snake scales, burning his eyes.

“Damn.” He leaned against the bridge rail, rain dripping from his chin into his collar, cold enough to make him shiver.

His fingers brushed something strange when reaching for his cigarette pack; he drew out a yellowed photo, breath catching.

In 2008, Song Zhao wore an ill-fitting police uniform. The two posed with “V” signs in front of a pile of broken bricks at a homicide scene. Song Zhao’s white glove still held a piece of bloody wall, dried to deep brown, the photo’s edge curled from repeated handling.

On the back, Song Zhao’s handwriting—crooked but strong—read: “Investigating is not about rank, only right and wrong.” The ink was blurred, as if soaked then dried.

As the rain eased, Chen Mo pressed the photo to his chest.

The warmth inside his uniform seeped through the photo paper, burning like a fire set to his lungs.

At ten in the morning, as the city bureau’s electronic screen lit up with the bulletin, Song Zhao turned away.

He didn’t look at the reporters crowding the door, didn’t hear their shouts of “Mr. Song,” only stared at the news push on his phone—“Irregular deletion of duty records, accountability procedures initiated.” The accompanying photo was a surveillance shot of Zhaoyang Bridge from years ago, the blurred red sedan’s taillights faintly revealing a flying figure.

The cold air of the city funeral home swept in, thick with sandalwood and disinfectant, striking his forehead.

On the urn’s porcelain photo, Song Jianguo wore the 99-model uniform; the mole between his brows was identical to Song Zhao’s.

He lit three sticks of incense, the sparks dancing at his fingertips, burning him enough to flinch. “Dad, they’re scared I’ll remember… It means what you wanted to investigate really existed.”

When he took out the copy from his pocket, the paper’s rustle echoed in the empty hall, like a snake crawling on dry leaves.

In the lower right corner of the 2003 land requisition record, a tiny handwritten note shone gray under the light: “Song Jianguo interviewed;
