The Observer's Trap

The damp, moldy stench in the ventilation duct slowly spread along the rusted metal walls, its pungent odor slipping through Lin Xiu's nostrils and into his lungs.

He pressed his knuckles against the nano-interface at the back of his neck. The burning pain there felt as though it had been repeatedly ground by red-hot pincers, waves of electric stinging spreading down his spine.

The Oracle System's data stream flickered across his retina in glaring blue light, subtitles pouring down like a rainstorm—"Intrusion source: Nanocore."

His temples throbbed as if countless fine needles were tapping against the inside of his skull.

"Marco mentioned timeline rejection..." he murmured, tearing off a sleeve from his lab coat to wipe the cold sweat from his brow.

The metal watch reflected a cold silver-white gleam, revealing the shadow buried deep in his eyes. "Now even my core is leaking signals... The Time Management Authority can't possibly be this passive... They're waiting for me to expose myself."

The laboratory alarm continued to buzz through his phone like a swarm of bees lying in wait beside his ear, making his eardrums ache faintly.

Lin Xiu's fingers tightened around the phone until his knuckles turned white, his nails nearly digging into his palm.

He suddenly recalled Marco's whisper before he vanished: "Quantum Sentinel"—it was the first time he had heard that title from someone else's lips since crossing over. Like a fine needle piercing deep into his memories, it stirred a dull ache.

The Nanocore trembled softly in his chest. He could clearly sense the silver fragment resonating with it, like two iron filings drawn together by a magnet, pulling at each other through an invisible force.

"Oracle, how much energy would it take to simulate a temporal prediction frequency?" He turned and headed for the duct exit, his heels striking the rusted iron plating with hollow echoes. Every step sounded as though he were treading across the skin of an abandoned drum.

"A high-tier fragment can sustain a false disturbance for three hours," the system replied with mechanical calm. "But it will expose the armor's quantum signature."

Lin Xiu paused.

Cold wind poured in through the vent, lifting the disheveled strands of hair before his forehead and carrying the dampness of night rain that had not yet dried.

He stared at the dim yellow streetlight filtering in from the end of the duct and curled his lips into a cold smile. "Expose it? That's exactly what they want."

At two in the morning, Brooklyn Laboratory was shrouded in pale blue security lights, with a faint ionized scent floating in the air.

Lin Xiu stood before the quantum chamber on the third basement level, his fingertips flying over the control console. Nanoparticles surged from the interface on his wrist and condensed into a translucent web of light in the air.

The faintly glowing particles were like spider silk woven from stardust, creating a false ripple in spacetime amid the darkness.

It was a "Spacetime Disturbance Wave" forged from his core energy, its frequency deliberately adjusted to the band most sensitive to Time Management Authority trackers.

"It begins." He took two steps back and watched the starlight flicker within the web. His Adam's apple moved, and his heartbeat gradually accelerated with the web's pulses.

In the alley outside the laboratory, Alia Kroll's Temporal Anchoring Device suddenly emitted a piercing shriek, like a high-frequency tuning fork exploding beside her ear.

She crouched behind an abandoned dumpster, her wine-red hair tousled by the night wind. The mutant bloodline in her left hand caused her pupils to glow faintly amber.

Frigid air carrying the scent of rain and motor oil rushed toward her.

"Finally." She let out a soft laugh, predator's excitement woven into it, and pulled a silver disc from her tactical waist pack—it was a capture net capable of locking down spacetime coordinates.

The instant the disc touched the ground, the laboratory windows suddenly erupted in blinding white light, shards scattering in every direction like hail.

As Alia looked up, she saw a figure standing in the shadow of shattered glass, pale golden patterns on his wrist moving beneath his skin like living snakes.

"What exactly do you want?" Lin Xiu's voice was low, yet it pierced the night like an ice pick, its chill cutting through the air.

Alia's fingers paused on the disc. When she looked up, a professional smile had already settled on her face. "Mr. Lin, I'm only here to confirm whether you've become a 'contamination source.'" She rose to her feet, her boots crunching over broken glass with startling clarity, like the pendulum of a countdown clock. "The timeline has been too fragile lately. The Battle of New York, the Mind Stone..." She tilted her head, her gaze sweeping over the glowing patterns on Lin Xiu's wrist. "The Nanocore inside you is far more dangerous than any of those."

Lin Xiu took a step forward. The armor's low hum vibrated through his chest, as if some sleeping beast had awakened.

He noticed that Alia's right hand had remained hovering near the holster at her waist—it was not a conventional firearm, but the Time Management Authority's signature "Corrector."

"So you monitored me, infiltrated my laboratory, and even used Marco as bait?" Coldness surfaced in his voice like the first thin layer of ice forming across a winter lake. "Marco's timeline rejection—was that your doing too?"

Alia's smile froze for an instant.

Her mutant bloodline allowed her to vaguely sense the fluctuations of timelines. At that moment, the timeline around Lin Xiu resembled a crumpled ball of paper, glowing with a dangerous violet light.

"Marco was only a volunteer." She licked her lips, her voice slightly hoarse. "What the Time Management Authority needs are controllable variables, not sources of chaos. The way you analyzed the Mind Stone while fighting the Chitauri..." Her gaze swept across the glowing patterns on Lin Xiu's wrist. "It was too tempting."

"So I'm an experiment." Nanoparticles glimmered at Lin Xiu's fingertips as the Oracle System analyzed Alia's microexpressions—pupil contraction for 0.3 seconds, a faint twitch in the muscles at the corners of her mouth. Signs of a lie.

"A candidate." Alia suddenly raised her voice, blue light spilling from the Corrector in its holster. "In the entire multiverse, there isn't a second person capable of mastering quantum entanglement. We only wanted to..."

"Enough."

A thunderous roar split down from overhead, as if the sky itself had been torn apart.

The moment Lin Xiu looked up, the sky seemed to split open under a colossal axe, two rifts cleaving through it. A figure wreathed in lightning fell from the north—it was Odin. His spear, Gungnir, shone with golden light powerful enough to burn through dimensions, aimed directly at Lin Xiu's heart.

Purple mist poured from the southern rift, and Vela Knox stepped out. Her robes still carried the sandalwood scent of Kamar-Taj, while the portal forming in her right hand faintly revealed the phantoms of six Time Stones.

"The power of time must not be defiled." Odin's voice shook the ground until it cracked. "The energy within you is mixed with the origins of Asgard and Earth."

"But he has already touched the boundary of the laws." Vela's voice was colder. Her gaze swept over the glowing patterns on Lin Xiu's wrist. "The Ancient One said that the true player has yet to make a move... Perhaps it is you."

Lin Xiu felt something explode in the depths of his core.

Nanoparticles surged forth like a golden flood, condensing over his body into armor in Oracle Form—this time, not the patterns of a tactical assault, but those of the final phase.

The energy matrix in his chest suddenly lit up. The crimson of the Mind Stone and the deep blue of the Tesseract twisted together within it like two flames that could never be extinguished.

"Who exactly am I?" His voice mingled with the armor's roar. "Or are all of you merely actors in another script?"

The answer came in the form of a black hole suddenly opening beneath his feet.

It was a darkness purer than any temporal rift, carrying a gravity that devoured all things.

The instant Odin's spear thrust toward him, Lin Xiu saw shock flash through Vela's pupils, while sparks burst from Alia's Corrector—all movement slowed, like a recording put on pause.

At the very last moment, he heard the Oracle System's notification. "Origin energy fragment resonance detected... Timeline Reboot Program activated."

As darkness wrapped around him and he fell, he remembered Marco's tears before he disappeared.

The way that tear had hung in midair looked exactly like the entangled photon pairs in the laboratory—perhaps every meeting and parting was an equation already written by the universe?

Before his consciousness sank into darkness, he vaguely thought: When I wake next time, which timeline's dawn will it be?
