Chapter 50 – The Broken Shoelace

The fluorescent screen in the monitoring room cast a cold white glow deep into the night, and Shen Mo’s shadow was projected onto the wall like a block of solid lead. His index finger hovered over the keyboard, knuckles whitening from tension—this was the seventh time in a row he had replayed the last seven seconds of the exhibition hall’s surveillance footage.

In the video, the shadow of a ballet shoe traced a gleaming arc on the floor, but the final bow, which should have been completed, was abruptly halted at the left foot. At the moment the black ribbon snapped, the shadows of the thirteen exhibits simultaneously drooped. The glass display cases trembled faintly on camera, as if struck by invisible hands.

“0.7 hertz,” he muttered softly at the spectrum analysis software, the tip of his nose still stained with dried blood. Earlier, when his nose bled, he hadn’t paid it much mind, but now he suddenly recalled that from three o’clock in the afternoon until closing, the museum’s psychological counseling office had registered seven cases of dizziness—a cognitive disorder in the human brain occurs at 0.7 hertz, a study he had just read last week in the Journal of Neuroscience.

The mouse wheel suddenly jammed, and he realized his palm was drenched in sweat. A breeze from the ventilation shaft brushed the nape of his neck, carrying a faint metallic scent that resembled the odor drifting from a mortuary cold storage.

His phone vibrated on the desk; it was a message from Su Wanying: “The ballet shoe’s display case is cracked.”

As Shen Mo’s footsteps echoed through the exhibition hall, the motion-sensor lights brightened one by one. Su Wanying stood before the glass display case, the cuffs of her white coat dusted with pale golden phosphorescent powder. When she bent down, the tips of her hair swept over the radiating cracks along the case’s edge—fractures that began at the left shoe’s toe, resembling a river cracking beneath ice.

“It was perfectly fine when it was first put in storage,” she whispered, gloves lightly tapping the inner wall of the display case. “Temperature was controlled at 22 degrees Celsius, plus or minus one, humidity at 50%. These are the ideal preservation conditions for top-tier relics.”

Shen Mo leaned in to examine the crack’s trajectory and suddenly noticed a red mark on the back of her left hand—a fresh wound from when she had fallen earlier, still oozing tiny beads of blood.

“You should treat that wound first.” He frowned and reached out to pull her toward the medical room, but she sidestepped him.

“Look here.” She used tweezers to lift some residue from the left shoe’s tip and moved to a shaded corner.

Under the cold light in the dark compartment, the phosphorescent powder that should have oxidized over time instead glowed with an eerie blue light, forming a line of tiny letters on the shoe’s tip: “Almost… enough.”

Shen Mo’s pupils contracted slightly. He pulled out a ultraviolet lamp and shone it on the inscription. The fluorescent particles along the edges of the letters wriggled slowly, like grains of sand stirred by a breeze.

“This isn’t paint.” He dipped a cotton swab to collect a sample. “It’s some kind of bioluminescent protein, but its half-life has shortened at least tenfold.”

At that moment, Su Wanying’s phone rang. Xiao Wu’s voice exploded from the speaker: “Sister Su! The environmental monitoring data is acting weird—the temperature in the exhibition hall dropped from 22 degrees Celsius to 15 between three and six after closing, and humidity shot up to 98%, but the air conditioning wasn’t even on!”

Shen Mo suddenly recalled the metallic scent near the ventilation grille. He pulled up the museum’s floor plan on his phone and pressed hard on the exhibition hall’s location. “Is the cold source underground?”

“I checked the building blueprints—the air raid shelter from the Republic of China era is right beneath the hall,” Xiao Wu’s keyboard clicks sounded rapidly. “But it was sealed off thirty years ago, so it shouldn’t be possible… Wait, there’s thermal imaging!”

The three stared at the dynamic image on the phone screen: a black silhouette of the exhibition hall’s center, where a pale blue halo was spreading like ink diffusing in clear water.

Temperature readings at the edge of the halo showed minus 12 degrees Celsius, a stark contrast to the surrounding 22-degree environment.

“It’s frost,” Su Wanying said suddenly, her gaze fixed on the ballet shoes in the case, eyes churning with something unspoken. “My grandmother once said that things with too much obsession—when they die, they still fill their bones with cold air.”

When the monitoring room door was knocked, Director Lin stood outside holding a camera, the lens cap swinging from his neck.

“Got something interesting to show you,” he said, sliding a hard drive into the computer. Time-lapse footage began to play—

After closing, moonlight streamed through the glass walls, casting blurred shadows of the thirteen exhibits onto the floor.

At midnight, all the shadows suddenly moved in unison, as if pulled by invisible strings, forming a circle in the central courtyard. Every shadow’s “head” bowed toward the ground as if in silent mourning.

One o’clock, two o’clock, three o’clock; after three cycles, at the fourth chime, the ballet shoe’s shadow suddenly lifted its “head.”

Its “right foot” stepped forward half a pace, its toe touching the ground in a posture completely different from the original bow, yet carrying an indescribable familiarity—as if it were a rehearsed move that was never fully completed.

“This is…” Su Wanying’s fingers clenched into her palm.

“It’s imitating,” Shen Mo’s voice was like breaking ice, “imitating the ‘unfinished.’” He pulled up rehearsal footage of the dancer from when she was alive and paused on a flawed take: “Look here, at the 1983 National Performance, she slipped half a step during rehearsal and got scolded by the director for half an hour.”

Suddenly, Director Lin’s camera emitted a buzzing sound; the on-screen time read exactly four a.m.

All three turned toward the exhibition hall—there came a faint “click,” like something cracking.

Xiao Wu’s call came through again: “Forensic Doctor Shen, I analyzed data from all city psychiatric clinics. In the past week, thirteen people reported the same dream: sitting in a theater applauding while the dancer never takes her bow. The louder the applause, the heavier their bodies grow, until they’re nailed to their chairs.” His voice tensed. “I built an emotional feedback model… The ‘breakpoints’ you created have become its sustenance.”

Shen Mo’s temples throbbed violently.

He grabbed his coat and headed toward the hall but was stopped by Curator Chen in front of the display case.

The old curator’s suit was askew, his tie loosely hanging, eyes bloodshot. “You want to burn it? These are relics of the 1983 dancers! History!”

“It’s killing people,” Shen Mo’s voice was as cold as a scalpel. “The pupil dilation and endorphin secretion levels of the girl who collapsed in the subway last Friday matched exactly with victims when these shoes activate.”

“That’s coincidence!” Curator Chen slapped the display case, the glass trembling in response. “You don’t understand the value of these antiques—they’re alive, they are…”

“Why thirteen?” Su Wanying suddenly cut in, clutching a stack of collection lists, her knuckles white. “I initially reported only twelve. The thirteenth was automatically added by the system.” She flipped to the last page; the approval signature suffocated everyone—her own signature, written in a firm hand, but dated two weeks ago, the day she had collapsed and been hospitalized after the ‘resonance ritual.’

The clock in the monitoring room struck five.

Shen Mo looked at Su Wanying’s trembling fingertips and suddenly recalled their first meeting, when she stood before a bronze exhibit and said, “Every relic has its own story; we are merely the narrators.” At this moment, her eyelashes cast shadows beneath her eyes like a frightened butterfly.

“It has chosen its host,” Shen Mo whispered.

His words fell like a stone into the deathly silence.

Suddenly, Su Wanying snatched up the tablet on the desk and opened the museum’s collection management system.

In the recent operation records on the login screen, the entry for “Adding 1983 ballet shoes” was made under the ID “Su Wanying,” timestamped precisely at 3:17 a.m. on the day she had slipped into a coma—when she was lying in the ICU, the beeping of the heart monitor spoke louder than any testimony.

Dawn tinted the sky pale.

Shen Mo rubbed his throbbing temples and turned toward the filing cabinet in the monitoring room.

He pulled out a stack of yellowed clippings, the cover marked in red ink: “Stage Accident Records (2013–2023).”

As his fingers traced the headline “2018 Workers’ Cultural Palace Collapse Accident, 13 Dancers Trapped,” Su Wanying gasped behind him—

In the display case, the left shoe’s ribbon had somehow been retied.

The black silk ribbon fluttered gently in the breeze from the ventilation shaft, tied in a perfect bow—identical down to the last detail to the ribbon the dancer wore in the 1983 performance photo.
