Chapter Forty-Eight – These Things Are Watching Each Other

Su Wanying’s fingertip hovered over the phone screen for three seconds.

Chen Curator’s message was still lit up: “Rehearsal at 9 a.m. tomorrow,” the words stinging her eyes with fatigue.

The cool air from the dissection room’s air conditioner brushed the nape of her neck, and suddenly she recalled how Director Chen had personally locked the exhibit hall’s keypad door last week during setup—yet in the silent pocket of Shen Mo’s work uniform lay the backup magnetic card she had secretly prepared.

“The surveillance system is an old model from the city museum,” she whispered, placing the magnetic card into his palm, her voice like a sigh. “It switches to maintenance mode and blacks out for two minutes exactly at 3 o’clock.”

Shen Mo looked down at the silver card, his fingertip brushing over the rough edge.

Su Wanying had spent the night modifying it with a badge strip and a paperclip; he remembered seeing her in the office last night, piecing together circuit diagrams from shredded paper, glue staining her hair tips. “This will do.” He pocketed the card in his inner jacket and turned to push open the dissection room door.

The museum at midnight was like a frozen clock.

As they pressed close to the marble wall and walked toward the exhibit hall, Su Wanying could hear her heartbeat thumping against her ribs, counting each step.

Turning the corner past the bronze tripod display, the deep brown solid wood door finally appeared in view—the lightbox above it for the special exhibition “Echoes of Bygone Times” still glowing, the cold white light casting the last stroke of the character “Echo” like a crack.

The magnetic card’s swipe beep echoed crisply in the empty corridor.

The lock clicked open, and Su Wanying’s hand pressed lightly against Shen Mo’s back. “Wait.” Her fingertip transmitted warmth through the fabric of his uniform. “Director Chen said yesterday... all these relics were private donations. Even I haven’t seen the complete inventory.”

Shen Mo turned his head to look at her; his pupils narrowed to thin slits in the darkness. “So, what we’re looking for isn’t the inventory.” He pushed the half-open door, and the air of the exhibit hall flowed out—a mix of old wood’s mustiness, the cold metallic scent of glass display cases, and a faint hint of scorched paper, like old newspapers soaked and dried again.

The circular layout at the center of the hall became visible under the flashlight beam.

Thirteen exhibits were arranged evenly in a circle—the outer ring held faded costumes, chipped copper bells, glasses missing half a lens; the center was covered with old stage floorboards, the grain embedded with tiny fragments of red lacquer, like congealed drops of blood.

Shen Mo’s laser rangefinder cast a red light before the first exhibit.

They were a pair of ballet shoes, satin toes worn glossy, with scorch marks near the shoe’s opening.

He circled the display case with the device, the beam refracting off the glass’s angles and suddenly pausing. “Su Wanying,” his voice low, “come here.”

As she leaned closer, she saw complex geometric patterns flickering on the rangefinder’s screen.

The red beam started at the ballet shoes’ toe, refracted through the glass, passed through the shadow of the second exhibit—a wooden comb missing teeth—then reflected off the metal clasp of the third—a faded accordion—finally landing on the rim of the fourth exhibit—a tea-stained enamel cup.

“Continue.” His Adam’s apple bobbed.

When the red light completed its thirteenth circuit, the rangefinder beeped to indicate completion.

Su Wanying stared at the closed-loop trajectory on the screen, a shiver raising the hairs on her neck. “They’re not waiting for the audience,” Shen Mo’s voice was like ice. “They’re ‘watching’ themselves.”

“What are they watching?”

The answer came in a sudden burst of blue light.

Xiao Wu emerged from the corner of the hall, clutching an electromagnetic field detector, his hoodie slipped back, dust clinging to his hairline. “0.7 Hz.” He aimed the detector at the center floor; the waveform on the screen perfectly matched the brainwave patterns of the audience who had collectively fainted earlier. “Exactly the rhythm of dreams.”

Shen Mo grabbed Xiao Wu’s tablet; on the 3D scan, the ballet shoes were rotating.

The carbonized fabric fibers, magnified, revealed a fractal structure; every branching point connected like neural synapses to the scan data of other exhibits. “These aren’t relics,” Xiao Wu’s Adam’s apple bobbed. “They’re ‘echoes’—a ‘brain’ pieced together from thirteen fragments of memory.”

“A brain requires input.” Shen Mo tapped his finger on the tablet. “Input comes from—”

“Look at this.” Su Wanying’s voice suddenly trembled.

She crouched by the exhibit label printer, holding a crumpled note in her hand—an unsent draft of a label.

The handwriting was familiar—Chen Curator’s penmanship, each character for “day” written with an extra stroke. “March 17, 1983. Curtain call unfinished. The completion ritual requires thirteen pairs of eyes.”

Her fingernails dug into her palm as a flood of memories surged: the stage in her dream, holding intact ballet shoes, the audience seated below, the applause muted as if silenced.

“If the exhibition itself is the ritual...” she looked up at Shen Mo, her eyes reddened. “Then was I chosen from the very beginning?”

The sound of a cane tapping came from the exhibit hall entrance.

Old Cheng stood in the shadows, his white shirt faded gray, top button fastened. “That night when the fire started, she was still spinning.” His voice sounded like sandpaper scraping metal. “The thirteenth turn, half a beat from curtain call.”

“But the door was locked.” He raised his cane, its tip pointing toward the ballet shoes. “She said as long as someone remembers, the curtain call must go on.”

Shen Mo stepped forward slightly. “What if the ritual never finishes?”

“Then everyone gets trapped together in the final second.” Old Cheng’s smile was more bitter than tears. “The audience in the theater that night, the mountaineering team, the customers at the ice cream shop... they’re all waiting.”

“Waiting for the 0.7-second curtain call.”

As Shen Mo turned away, the microscopic tweezers in his lab coat pocket pressed sharply against his thigh.

He had prepared in the dissection room—a damping agent borrowed from the forensics department, applied to synthetic fibers so thin as to be nearly invisible. “How long will it take?” Su Wanying suddenly grabbed his sleeve, her fingertips unnervingly cold.

“To replace one shoelace fiber.” He slid the tweezers into her hand. “You handle the lighting.”

The glass of the display case shimmered with a faint blue under the flashlight.

Shen Mo’s breathing was quiet; the tweezers’ tip lifted a shoelace inside the ballet shoe. The fiber gleamed a natural beige under the strong light, stark against the surrounding charred sections. “This is the core conduction medium of the ‘echoes’.” His voice was steady as a precision instrument. “Replace it, and its resilience will drop to one-tenth.”

The moment the tweezers touched the fiber, the exhibit hall’s lights suddenly went out.

Su Wanying’s phone hit the floor with a sharp snap.

In the darkness, thirteen shadows simultaneously emitted faint scraping sounds—not cloth or wood, but like countless fingers clawing at glass.

Xiao Wu’s detector screamed from the corner, his voice echoing: “Electromagnetic signals are spiking! The resonance field is warming up!”

Shen Mo pressed his forehead against the display glass, feeling the chill seep through his skin.

His hand still clutched the synthetic fiber coated with damping agent; the other gripped the original fiber removed.

The “gaze” from the shadows pressed down on his back like tangible weight; he heard Su Wanying trembling but dared not look back.

When the lights flickered back on, the shoelace was already in place.

Su Wanying lifted her phone to shine light, seeing nothing out of the ordinary.

But Shen Mo knew—the synthetic fiber was waiting, waiting for the 0.7-second curtain call, waiting for the moment all eyes focused, and then... it would snap.

“Opening tomorrow.” He tore off his gloves, knuckles whitening. “Everyone must see—the curtain call breaking at the last moment.”

Old Cheng’s cane taps echoed behind them, gradually fading.

Xiao Wu turned off the detector, the glow from the screen casting a pale hue over his face. “I’ll stay in the surveillance room. If anything unusual happens, I’ll alert you.”

As Su Wanying bent to retrieve her phone, she caught sight of the ballet shoes’ reflection in the glass—the toe slightly lifted, as if someone gently tugged the shoelace.

She shivered, slipping the phone into Shen Mo’s hand. “You said corpses are the most honest witnesses.” Her eyes gleamed in the dark. “This time, we’ll turn the ritual into a corpse.”

Outside the museum at four in the morning, the first ray of dawn climbed over the dome.

Shen Mo stood at the surveillance room’s doorway, watching Xiao Wu adjust scores of screens.

The largest one faced the special exhibit hall directly—thirteen exhibits silent in the morning light, waiting.

“At nine tomorrow.” He touched the microscopic tweezers in his pocket. “They will come.”
