Chapter Seven: The Key Within the Furnace

The crimson cracks left by the three corrosive darts as they detonated against the rusted support structure spread like veins, rapidly consuming the metal framework beneath Kane’s feet. The structure groaned under the strain, and flakes of rust cascaded down. The gray uniforms of the task force shimmered amidst the rust-red mist, their polished masks reflecting a cold, sterile light.

"Contamination Carrier K-7, final warning," the lead Hound stated, raising an arm as their wrist device expanded into a hollow, dark muzzle. "Relinquish the illicit items."

Kane pressed his back against the cold metal wall of the control tower, his left hand gripping the black cube and the brass key so tightly his knuckles turned white. The 7.1Hz resonant frequency echoed in his mind, forming an eerie harmony with the crimson 70:21:58:37 displayed on his pocket watch. There was no time left—neither for the countdown nor for the pursuing hounds.

He jammed the black cube into his inner pocket, tightened his grip on the pocket watch, and as the support structure finally buckled, he threw himself toward the ventilation duct on the other side of the tower!

"Fire!"

Blinding blue light tore through the mist. Kane felt a searing sting brush his back as his protective suit instantly melted, leaving a charred hole. He slammed hard into the verdigris-covered metal pipes, a sharp pain shooting through his ribs, but the instinct for survival drove him to scramble forward, limbs flailing, until he dove into the narrow duct opening.

The pipe was thick with suffocating metal dust and the pungent stench of ozone. Kane crawled through the darkness, his own ragged breathing competing with the mechanical communications of the task force outside: "Target has entered the C7 ventilation system. Initiate corrosive gas injection."

Poison gas! Kane’s pupils contracted in the dark. He scrambled desperately forward until his fingers brushed against a protruding access panel on the pipe’s wall. The rusted screws gave way under his brute force, revealing a cramped maintenance shaft—a ladder well that dropped almost vertically.

There was no choice. He plunged into the shaft, surrendering to gravity as it dragged him toward the abyss. Above, the hissing of gas injectors began, and pale green toxic mist surged into the pipes like a living thing.

Falling. Darkness. The pocket watch pulsed against his chest like a second heart.

*Bang!*

Kane landed heavily on a pile of soft padding—discarded insulation material. He struggled to his feet, finding himself in a semi-circular maintenance chamber. The walls were covered in flickering gauges and frozen needles; in the center stood a massive, rusted circular valve, and embedded in its center was a keyhole.

It was no ordinary keyhole. Its shape was peculiar, with delicate grooves along the edges. Trembling, Kane pulled out the brass key and compared it to the outline—a perfect match.

But the black cube’s message had mentioned a "resonant frequency of 7.1Hz." Did the key need a specific frequency to activate?

He scanned his surroundings, his gaze landing on a row of vintage analog gauges on the wall. The needle of one pressure gauge was stuck at 7.1, with a strange set of markings around the edge of the dial. Kane lunged forward and twisted the dial with all his might.

*Click.*

The dial rotated 71 degrees. The entire maintenance chamber began to vibrate, and the needles on the wall gauges swung wildly! The central circular valve emitted a low hum, and a faint, ghostly blue light illuminated the ring around the keyhole.

Now! Kane inserted the brass key. It began to vibrate at a high frequency, emitting a 7.1Hz buzz. The layers of rust on the valve peeled away in flakes, revealing the pristine metal beneath. With a hiss of hydraulic release, the heavy valve slowly swung open, revealing a spiral staircase leading downward.

At the end of the stairs lay a small data terminal room. The terminal screen was long shattered, but an inconspicuous slot on the base caught Kane’s attention—the dimensions perfectly matched the black cube.

He pulled the cube out with trembling hands and pressed it into the slot.

*Hum—*

The entire room erupted in a ghostly blue light! A complex, web-like structural diagram appeared in the air, with a rotating Ouroboros symbol at its center. Four nodes pulsed with red light—New York, London, Cairo, and Tokyo. A golden thread extended from the Cairo node, pointing toward a heavily encrypted sub-module deep within the network: [The Primordial Ring].

Below the projection, a line of text appeared:

[Physical key authentication successful. Gateway to the Sun-Melt Core database opened. Warning: Access restricted to Dr. Aldrin’s biometric signature only.]

Dr. Aldrin. Himself.

Kane pressed his palm against the biometric scanner on the terminal base. A blue light swept over him, and the system emitted a crisp chime.

[Identity confirmed. Welcome back, Dr. Aldrin.]

The terminal base suddenly sank, revealing a hidden safe. Inside lay a crystal-clear prism with golden liquid flowing within—a memory storage unit!

The moment Kane touched the crystal, the entire room shook violently! A piercing alarm echoed through the space:

[Unauthorized spacetime jump detected! Task force has breached the outer perimeter!]

The Time Bureau’s hounds had broken through the defenses. There was no time left.

He snatched the crystal, and the countdown on his pocket watch began to flicker rapidly: 70:21:30:15. As the crystal made contact with the watch, a blinding golden light exploded!

Kane’s vision was flooded with countless fragments of memory:

—A younger version of himself standing in a laboratory, showing the blueprints of the "Ouroboros Project" to Thorne.

—The black-clad Director nodding coldly: "The carrier must be willing to endure the pressure of the cycle."

—Himself signing a document, his eyes resolute: "To save more timelines, I am willing to become the anchor."

—The excruciating pain of the first cycle being initiated, his body torn apart in a scream of agony.

—During the thousandth cycle, planting the first hidden command within the data stream.

—An aged version of himself in the Tokyo lab, his eyes filled not with relief, but with hope as he pressed the release button...

Through the torrent of memories, a coordinate emerged with absolute clarity: the lowest level of the Cairo Sun-Melt Core, the center of the quantum server array, the physical location of the Primordial Ring!

The golden light faded, and Kane found himself kneeling on the floor of the terminal room, the crystal now reduced to powder in his hand. From the distance came the screeching sound of metal being torn apart. The task force was close.

He gripped his pocket watch, the target for his final jump clear: Cairo, the Sun-Melt Core, the origin point to end the cycle!

As the first corrosive dart pierced the door of the terminal room, Kane’s silhouette dissolved into the golden light.
