Hunt Countdown in the Subway Shadows

The silver arrow swirled around Lynn's fingertips, trembling like a living thing as it pointed northeast.

Its silver glow flickered over his dark fingertips like flowing mercury.

Following its direction, he slipped into an abandoned Brooklyn subway station. The moment he stepped inside, damp, chilly air brushed the back of his neck like icy tentacles, making every hair on his body stand on end.

The air thirty meters underground carried the stench of decay, filling his nostrils with the scent of age and abandonment.

The Oracle System said quantum afterwaves from a Tesseract fragment still lingered here, but what unsettled him more was that Asgardian divine-script code was still dancing across his retina like a silent warning. Its flickering glow was especially glaring in the darkness.

"The temperature is 12.3°C, humidity 89%." The system's voice was kept extremely low, as though afraid of disturbing the underground silence. "There is a rust breach in the ventilation duct. Avoid the third pillar on the left." Lynn braced himself against the mold-speckled wall and edged downward. When his hand touched it, the rough texture felt like the furrows carved by time.

The soles of his combat boots slipped on the water-filmed rails. The clash of metal sent fragmented echoes bouncing through the tunnel, reverberating through the hollow space like countless pairs of eyes spying on him.

He immediately held his breath—the nanobots inside this body surged through his veins toward his fingertips, condensing into a translucent shielding membrane across his palm.

The membrane glimmered with faint blue light, its barely visible radiance mysterious and eerie in the darkness.

That was when the blue light entered his field of vision.

At the end of the tunnel, a thumbnail-sized fragment floated above a concrete pedestal. Like a crushed star, it shone brilliantly blue in the darkness, as though proclaiming its extraordinary nature.

Lynn's pupils constricted sharply, and his throat tightened—he had seen similar light in the laboratory. On that day, amid the blue flare from the quantum collider explosion, the nanocore had fused into his flesh and blood in exactly this way.

That mysterious laboratory had been the turning point of his fate, where countless secrets and dangers had begun. "Low-grade fragment. Energy stability: 78%." There was a hint of mechanical excitement in the system's voice. "Type III extraction procedure recommended. Estimated time: 17 seconds."

He crouched down. Nanobots emerged from his sleeve and wove themselves into a web-like energy claw around his fingertips.

The energy claw shimmered faintly, quivering gently as though it possessed life.

But the instant it touched the fragment, metal scraping sounded from deep within the tunnel—as if some heavy machine were grinding over the rails. The rhythm of "clack, clack" grew clearer, pounding against Lynn's heart like a heavy hammer.

Cold sweat instantly seeped down the back of Lynn's neck. The nanoclaw snapped back beneath his skin, and he slid along the tunnel wall into a recessed hollow.

The stone wall of the hollow was cold and rough against his back, sending a chill through him.

"Thermal scanner activated." The system's warning came before the footsteps. "Seven biological signals detected. Energy signatures match Chitauri ground forces." Lynn held his breath as six figures clad in dark purple armor emerged from around the bend, their armor glinting with an eerie sheen in the weak light.

The one in front was half a head taller than the rest, with a totem of crossed bone blades engraved on her shoulder armor—it was Carl Weiss, the Chitauri elite commander Lynn had seen in S.H.I.E.L.D. files.

"The energy disturbance is here." Carl's throat modulator emitted a raspy electronic voice, her clawed fingertips pointing toward where Lynn was hiding.

The voice seemed to come from hell itself, making Lynn's heartbeat suddenly accelerate. He could hear his own blood roaring against his eardrums.

His left hand quietly pressed against his waist as nanobots crawled along the patterns of his skin and into the armor interface—the tactical-form activation sequence flashed wildly within the Oracle System, but revealing himself now would be suicide.

"Adjusting temperature to 12.5°C." The system's voice suddenly became urgent. "Release interference swarm. Simulate dripping-water frequency. Three, two, one—"

A "drip, drip" of water sounded through the tunnel, perfectly overlapping with an actual seepage point twenty meters away.

The dripping was especially clear in the silent tunnel, like a countdown to fate.

The red light from the Chitauri soldiers' scanners swept over Lynn's position, paused before the recess, then slowly moved away.

The red glow flickered in the darkness like a demon's eye.

Carl's antennae suddenly stood upright. She turned and hissed several words in an alien language, and the soldiers immediately spread out in a fan formation.

Lynn watched as the nearest soldier approached to within three steps of him. The thermal detector on its gun barrel lit up with a piercing red glow.

That red light was like a sharp blade, stabbing into Lynn's eyes.

His fingernails dug deeply into his palm, and the sharp pain made him even more alert.

Nanobots churned beneath his skin and slipped out through cracks in the ventilation duct—that was the backup plan he had hidden in the ceiling of the tunnel.

When the Chitauri soldiers' communicators suddenly erupted in a piercing shriek, a cold gleam flashed through Lynn's eyes.

He controlled the nanobots to entangle the communication lines, detonating them precisely at the system-marked "overload threshold." The blast wave overturned two soldiers. Metal fragments grazed past Carl's shoulder armor and struck the wall in a shower of sparks.

The sparks flickered in the darkness like sparks of hope.

"Now!" Lynn growled as he sprang from the recess.

His heart was filled with a firm resolve to protect the fragment. It might be the key to saving humanity, or the key to unraveling the mystery of his origins.

His right hand carved a silver arc through the air. Nanobots wrapped around the fragment and retracted into his palm, while the armor core suddenly grew scorching hot—blue ripples spread from his chest across his entire body, and the patterns of tactical assault form lit up beneath his skin like flowing lightning.

"Human!" Carl's roar made the tunnel hum. Her weapon spewed a purple beam that blasted a charred crater where Lynn had just been standing.

The purple beam shone brilliantly in the darkness, accompanied by a pungent smell.

Using the explosive power of his new form, Lynn leaped onto a crossbeam near the tunnel ceiling. Nanobots reassembled in his palm, and the cold gleam of the electromagnetic pulse crossbow reminded him of the particle gun in the laboratory. "Target locked: command terminal." The system's prompt was drowned out by gunfire. The instant he pulled the trigger, the bolt pierced precisely through the weak point beneath Carl's arm guard.

In the firelight of the terminal's explosion, the Chitauri soldiers' weapons all malfunctioned.

Lynn landed where the fragment had originally floated and watched the last soldier collapse into the darkness.

Just as he was about to breathe a sigh of relief, the Oracle System's alarm suddenly pierced his eardrums. "Higher-density energy fluctuations detected!

Source..."

"The Helicarrier," Lynn finished for the system.

He stared at the still-heated fragment in his palm and could feel the nanocore cheering—but clearer still was the tremor coming from above, as though some colossal entity were tearing through the clouds.

The tremor grew stronger and stronger, like the prelude to the end of the world.

In the daylight leaking through the tunnel vent, he saw his shadow stretched impossibly long.

Along the edges of that shadow, a faint golden glow was seeping out—the exact same color as the Asgardian divine script from before.
