The Hunt Countdown in the Subway Shadows: Continuation

In the dim subway tunnel, patches of peeling plaster had fallen from the walls, exposing old bricks and filling the air with a heavy moldy stench. Like an invisible hand wrapped in rust, it surged straight into Lin Xiu's nostrils.

His nanotech combat boot crushed the third loose rail hard, producing a sharp clang.

The Oracle System projected a pale green route map across his retina. The coordinates lay thirty meters ahead—the abandoned maintenance bay on the C-7 branch line.

In the faint light, a weak cluster of blue radiance flickered there like breathing. It glimmered in the darkness like a mysterious eye.

"Energy fluctuation frequency: 0.32 Hz. It matches a secondary Tesseract fragment." He lowered his voice, and the nanocommunicator at his throat relayed the information to Dr. Novak through his earpiece.

As he spoke, he could clearly hear his own breathing echoing through the silent tunnel.

The Nanocore beneath his breastplate trembled faintly with every breath, as if answering some ancient summons.

That slight vibration traveled through the breastplate to his skin, bringing an unusual sensation.

The quantum storm from when he crossed over three days ago churned in his memories. He touched the pale cyan mark at the back of his neck, the trace left by the Nanocore merging with his body. Now, as he neared the target, it was heating up slightly, as though carrying the lingering warmth of the quantum storm.

"Watch the coverage area of the shielding field." The doctor's voice carried static, buzzing in his ear like a fly. "Chitauri scanners can detect energy leaks as low as 0.01 microteslas. Last time in Queens, it was because..."

"Understood." Lin Xiu cut her off.

He crouched and tapped his wrist armor with his fingertips. Thousands of nanobugs poured from the armor's seams, weaving a translucent mesh barrier around the maintenance bay.

The sound of the nanobugs writhing was like a fine, rustling hiss.

Pale violet light, like crushed starlight, spread along the path of the swarm and completely wrapped the blue glow in a cocoon.

The faint light flickered over Lin Xiu's visor, reflecting his stern expression as well.

Just as the nanobugs completed their final loop, the sound of metal treads grinding over rails came from deep within the tunnel. It drew closer and closer, like dull drumbeats pounding against Lin Xiu's nerves.

Lin Xiu's pupils contracted sharply.

That sound was too familiar—an assault vehicle of the Chitauri Ground Forces. Vibranium Alloy was embedded between every tread, producing a muffled clatter like interlocking gears as it moved.

He could picture the assault vehicle's massive body, its treads rolling over the tracks and kicking up dust.

He pressed the back of his hand against an indentation in the tunnel wall. The armor's optical camouflage activated instantly, and his entire body seemed to melt into the darkness.

The icy touch of the tunnel wall seeped into his palm, tightening his nerves further.

"Doctor, cut the satellite signal." His voice was two degrees lower than usual. "We have uninvited guests."

Keyboard tapping sounded through the earpiece. "Seven heat signatures locked. They're infiltrating from the B1 entrance... Wait, the lead one's thermal radiation is abnormal. Commander-class."

Red dots flashed across Lin Xiu's retina.

Seven red points formed a fan shape around a bend three hundred meters away. The one at the center was larger than the others and was approaching with steady steps.

He could almost see the seven figures advancing through the darkness, their heavy footsteps accompanied by the faint clink of their equipment.

He could hear the Chitauri soldiers' mechanical breathing now, mixed with the hum of the assault vehicle's engine, like the drumbeat of approaching death.

That mechanical breathing sounded like metallic panting, cold and utterly inhuman.

"High-frequency scanners activated." Novak's voice suddenly tightened. "They're searching for the energy source!"

Lin Xiu's fingers tapped rapidly against his armguard.

The Tactical Form's environmental adaptation function activated at once. The molecular structure on the surface of his nano armor began to reorganize, and its temperature dropped by 2°C per second, quickly blending into the underground's constant 15°C.

He could feel the surface of his armor gradually cooling, as though coated in frost.

At the same time, he released a small swarm of interference bugs and had them cling to the pipes on the tunnel ceiling. Three seconds later, steady dripping echoed through the tunnel, perfectly overlapping with the sound of real water droplets.

The dripping echoed through the silent tunnel, like the footsteps of time.

"Targeting offset by twelve meters." Novak gave a quiet laugh. "Those tin cans actually bought it."

The cluster of red dots stopped in the middle of the tunnel.

The leading figure removed her helmet, revealing gray-blue skin with a metallic sheen—Carl Weiss, a notorious "Hunter" among the Chitauri Ground Forces. Lin Xiu had seen her photo in the S.H.I.E.L.D. files.

Carl's skin shone like a cold sheet of metal. Her eyes were like crimson gemstones, radiating an icy gleam.

She tilted her head, her scarlet compound eyes sweeping over both sides of the tunnel while her fingers unconsciously stroked the particle gun at her waist.

The particle gun had an unusual design, its body glowing with a dim blue light as though it contained endless energy.

"Something's wrong." Carl suddenly spoke, her voice like rusty gears scraping together. "The dripping... it's too regular."

A chill crawled up Lin Xiu's neck.

He had encountered too many opponents like this—elites whose battlefield instincts were sharper than any instrument, often the most dangerous variables.

A flicker of tension crossed his mind, but even more than that, he anticipated the battle to come.

The Nanocore in his chest began vibrating faster, and the Oracle System calculated frantically: if he forced his way through now, his chance of victory was 37%; if he waited for the enemy to spread out, it would rise to 62%.

The Nanocore's vibration grew stronger and stronger, as though reflecting his desire to fight.

"Spread out and search." Carl waved a hand. The seven soldiers split into three groups. Two remained with the assault vehicle, while five advanced toward the maintenance bay in a fan formation.

The seven Chitauri soldiers were tall, their bodies seeming like a fusion of machinery and biology. Their weapons were uniquely designed, the particle guns covered in intricate patterns with dim light gleaming from their muzzles.

When one soldier's boot crushed a piece of gravel, Lin Xiu locked onto the communicator on its shoulder armor—it was the signal hub for the entire squad.

The opportunity had come.

He snapped his fingers without a sound.

The nanobugs hidden in the ventilation ducts poured down like black rain, slipping through the soldier's collar and into the communicator port.

The instant the nanobugs entered the communicator, a faint sizzling sound arose.

Three seconds later, the soldier's particle gun suddenly flashed with blinding white light—Lin Xiu had remotely activated its overload program.

Boom!

The blast wave sent the two nearest soldiers flying.

Firelight instantly illuminated the dark tunnel. A wave of heat rushed over him, scorching Lin Xiu's skin.

In the firelight, Lin Xiu shot toward the maintenance bay like an arrow released from a bow.

The moment the blade formed by the nanobugs sliced open the bay door, the blue glow suddenly surged, like a crushed star falling into his palm.

The blue light stung his eyes, and even its radiance seemed to carry a strange heat.

Ding—

The Oracle System's notification mixed with the roar of blood in his ears.

Lin Xiu watched blue ripples spread across his breastplate as the armor's patterns reorganized. Streamlined tactical rails extended from the shoulder armor, three retractable electromagnetic spikes emerged from the armguards, and a dynamic prediction grid appeared in his visor's field of view.

His heart filled with anticipation for this new power, but he also faintly worried about the stronger enemies ahead.

[Baldur Armor: Tactical Assault Form] unlocked.

"Catch him!" Carl's roar pierced through the smoke.

The Chitauri soldiers' particle guns turned toward him at once, dense beams weaving a net of fire through the tunnel.

The beams were so bright they hurt his eyes, and the intense heat warped the surrounding air.

Lin Xiu bent low. The Tactical Form's thrusters sprayed pale blue airflow from his leg armor—he leaped onto a crossbeam at the top of the tunnel, as light as a leaf caught in the wind.

The force of the airflow made his body tremble slightly, while the howl of rushing air filled his ears.

"Electromagnetic pulse crossbow, deploy."

Nanobugs reassembled in his palm, forming a translucent crossbow. Dim blue arcs danced over its bolt.

The crossbow glimmered faintly, like hope in the darkness.

Aim, pull, release—all in one motion. The bolt struck Carl's command terminal with precision, and electricity raced through its metal casing, turning the million-dollar device into scrap.

Darkness instantly swallowed the tunnel.

The emergency lights flickered out. Only the faint glow of Lin Xiu's visor and the fragment's blue light in his palm continued to pulse.

He heard Carl's breathing close at hand. She was feeling around for her pistol, but Lin Xiu knew the battle was already over.

"Doctor, location confirmed." He peeled away the fragment's final protective layer, and blue light flowed through his fingers into the Nanocore. "Fragment absorption complete."

"Wait..." Novak's voice suddenly changed. "The Oracle System has detected a higher-density energy fluctuation!

The frequency... it matches the engine signature of an airborne carrier!"

Lin Xiu froze.

He stared toward the ventilation opening at the top of the tunnel, where something heavier than darkness itself was drawing near.

He could almost feel an invisible pressure continuously pouring in from the vent.

The Nanocore's vibration frequency suddenly spiked, as though answering a summons from the sky.

"Lin Xiu, that fluctuation..." The doctor's voice was cut off by static. "They're locking onto you."

The air in the tunnel suddenly grew thin.

Lin Xiu could feel his breathing quicken, and his chest tightened.

Lin Xiu stared at the blue light gradually fading from his palm, hearing his own heartbeat drown out every other sound.

He knew this was only the beginning—when the shadow of the airborne carrier covered Brooklyn, the real hunt would finally begin.
