Clash Beneath the Quantum Barrier

Lin Xiu tapped his knuckles twice against the windowsill, the glass reflecting his taut jawline.

The night wind seeped through the gap, carrying a faint, damp scent of rust.

Moonlight fell upon the Nanocore at the back of his neck, its silver patterns faintly glowing with his heartbeat—it was the Balder Armor issuing a warning.

A low hum reverberated beneath his skin, like some mechanical lifeform on the verge of awakening.

He knew Asgard's methods all too well. Odin's so-called "observation" had never been the end of things.

"Stealth Mode, activate," he said quietly.

Silver patterns raced up from his wrist like living creatures, covering his entire body in the blink of an eye. Even the sound of his breathing was filtered by the armor into a fine mechanical tremor.

The sensation became unfamiliar and cold, as if he were wrapped in a thin metallic membrane. Every contraction of his muscles came with a faint electric sting.

The Vibranium Particle Emitter in the corner began to hum. A Nanite Swarm emerged from beneath his skin, weaving a pale blue resonance field fifty meters underground in the laboratory. This was the result of three days spent reverse-engineering Stark Industries' Vibranium Sonic Technology, designed specifically to block spiritual-sense tracking.

A faint scent of ozone spread through the air, while blue light cast spiderweb-like patterns across the metal walls.

"Simulation synchronization rate: 92%." Data streamed across his retina, and the Oracle System's notification sounded with mechanical calmness.

Lin Xiu bent to adjust the simulator's parameters. As his fingertips brushed the metal console, the armor on the back of his hand suddenly turned warm, as though warning him of something.

The heat traveled through his skin to his nerve endings, making his heart tighten.

He looked up at the surveillance screen on the wall. In the footage, the night sky above Brooklyn's industrial district glowed an unnatural deep blue—the lingering energy traces of the Rainbow Bridge.

The edges of the screen were slightly warped by heat, as if flames had licked across the glass.

The air suddenly froze, like a balloon gripped by an invisible hand.

Lin Xiu's pupils contracted sharply.

He heard a vibration beyond sound, like a colossal bell tolling inside his skull.

It had no frequency, yet it pierced directly through his consciousness, shaking his cerebral cortex and making his teeth ache faintly.

As he turned, the laboratory's blastproof glass reflected a golden figure—Heimdall stood atop an abandoned factory three kilometers away, Eternal Sword in hand. Moonlight flowed over his silver armor, and his gaze, sharp as a poison-tempered blade, pierced toward the underground laboratory.

The distant wind swept up dust, weaving it into strands of gold beneath the moonlight.

"Spiritual-sense scan!" The Oracle System's red alarm blared.

Lin Xiu's temples throbbed. The Nanocore at the back of his neck began to heat up—the precursor to a mental-force assault.

Heat surged up his spine, like sparks dancing within his neural center.

He swiftly severed every external signal interface, retaining only the neural link between his armor and brain. His fingers flew over the console's virtual keyboard. "Anti-Mental Force Field, frequency 2.7 terahertz, activate!"

Invisible ripples spread from beneath Heimdall's feet.

The disturbance seemed to tear reality apart. Lin Xiu's vision abruptly warped, as if he had been thrown into a muddied pool.

A piercing buzz filled his ears, like countless needles stabbing into his eardrums at once.

He heard his own breathing grow ragged. Countless fine needles seemed to bore from between his brows into his skull, while his consciousness became like a crumpled sheet of paper, ready to shatter at any moment.

A burning sensation came from the armor's neural interface as it forcibly stabilized his brain waves. On the Balder Armor's tactical display, the "Mental Resistance" value plummeted at a visible rate: 87%, 72%, 59%...

"Time Prediction, activate." Lin Xiu gritted his teeth, tasting blood on his tongue.

He had bitten through his tongue. Pain became his only anchor to reality.

The diamond-shaped core in the armor's chest erupted with a dim blue glow. Countless overlapping visions of the future appeared in his pupils: the frequency at which the spiritual-sense ripples would oscillate in the next second, and the number of degrees the Anti-Mental Force Field needed to shift to deflect the impact.

Half a second was enough for him to seize that fleeting opening.

"Adjust the frequency to 3.1 terahertz!" he nearly roared the command.

The laboratory air suddenly boomed. The Vibranium resonance field and Anti-Mental Force Field interwove on the nanoscale, forming a translucent barrier.

The booming seemed to come from deep within his chest, shaking even his heart.

Heimdall's spiritual-sense ripples crashed against the barrier, triggering golden and blue energy ripples like two intertwined flames tearing at each other in the void.

The air filled with a scorched smell, and the ground trembled faintly.

Within Asgard's Rainbow Bridge Hall, Odin's fingertips struck heavily against the armrest of his throne.

His divine sight pierced through the Nine Realms, clearly seeing how that blue barrier on Earth distorted Heimdall's spiritual sense. "This mortal... can actually resist the Watcher's will?"

"My king, should I..." Lena Thorson pressed a hand to the Valkyrie Battleblade at her waist, the runes on her armor already glowing faintly.

The desire for battle gleamed in her eyes, while the scent of metal and storms seemed to drift through the air.

"Do not act rashly." Odin's voice was low and imposing, as though suppressing thunder.

"There is no malice in his energy fluctuations. If we intervene by force..." He narrowed his eyes, staring at the tangled light over Earth. "It will only deepen the fractures in the web of fate."

Lena's fingers tightened around the battleblade's hilt, then slowly loosened.

Seeing the rare gravity on her king's face, she ultimately stepped back half a pace—the duty of a Valkyrie was to execute, not to question.

In the underground laboratory, cold sweat beaded across Lin Xiu's forehead.

Sweat slid into his collar and ran down his neck, leaving behind a damp, chilly trail.

He could feel the spiritual-sense assault weakening, while the armor's Mental Resistance value began to rise: 63%, 78%, 91%.

When the final golden ripple was deflected by the barrier, he staggered and braced himself against the console, his knuckles white.

The icy touch of metal against his palm was his only true sensation.

"Ding—Spiritual Sense—Level One Decoding complete." A pale blue data file appeared over the armor's chest, data streaming through the air like a galaxy.

When Lin Xiu looked up, he found that every electronic device within three meters of the laboratory had gone black. A faint golden mark was left on the wall, like a burned rune—the lingering trace of Heimdall's spiritual sense.

He reached out and touched the mark. A weak electric sensation came from his fingertips, like the echo of some ancient language.

"Looks like I succeeded halfway," Lin Xiu said softly.

The Nanocore gave a soft chime deep within his consciousness, as if answering him.

The Oracle System's notification sounded again, this time carrying a trace of excitement. "Recommendation: analyze the decoded data immediately. It may yield key parameters for Asgardian spiritual-sense technology."

Lin Xiu looked down at the terminal, where the newly generated Spiritual Sense—Level One Decoding Complete file was displayed. Blue light patterns flowed around the file icon, as though waiting for something.

His fingertips hovered above the controls. The silver patterns on his armored wristguard grew faintly warm, as if urging him to make a choice.

Outside the window, the night had deepened, and blue light still gathered in the direction of the harbor.

The night wind passed through the window, stirring the loose strands of hair over his forehead and carrying the scent of a distant, unfinished storm.

Lin Xiu stared at that cluster of light, then at the file on the terminal. The light in his eyes gradually sharpened—some secrets had to be uncovered by his own hand.
