The light from the Anti-Entropy Core gradually receded like the ebbing tide, and Universe Seven, once shrouded in dazzling light, slowly returned to its former tranquility. Within this silence, Lu Li's data form trembled slightly like tiny ripples on a calm lake.

Suddenly, six afterimages appeared and disappeared in the light. They seemed to be Lu Li's clones, slowly rotating around him. Lu Li stared at these afterimages, a trace of thought flashing in his eyes.

He slowly stretched out his hand, as if drawn by some force, his fingertips involuntarily moving toward the seventeen-colored gem suspended in mid-air. The moment his fingers touched the gem, a strange feeling welled up in his heart.

This feeling wasn't from the gem's own warmth, but rather a subtle vibration, identical to the unique vibration of Lin Yue's Origin Time Thread. Lu Li's heart skipped a beat, realizing that there seemed to be some close connection between this seventeen-colored gem and Lin Yue.

At that moment, a calico cat swiftly leaped onto the metal platform etched with an ancient totem. Around its neck was a gear collar, the gears of which gleamed with metallic luster in the dim light.

The moment the calico cat stepped onto the platform, the gear collar emitted a faint humming sound. This humming resonated with the guardian hearts that had rekindled on the surrounding walls, and the entire space seemed to tremble slightly with this resonance.

"The energy readings are stabilizing, but..." Lu Li suddenly paused, the golden code calculating rapidly in the void, the data stream flashing wildly in his pupils, "There are still abnormal fluctuations in the quantum gap, and the remaining entropy energy of those black-robed men is converging towards a certain coordinate!" He called up the holographic star map, and a dark area at the edge of the star map was emitting a strange purple light, like an ink stain spreading on the fabric of the universe.

The calico cat's tail suddenly stretched like a whip, tiny arcs of electricity emanating from its fur. "It's the Mirror Universe! The legendary vessel of entropy, the exact opposite of the main universe!" Suddenly, everything began to spin in reverse, as if time had been reversed. The shattered image gradually pieced together in this strange whirl, revealing a shocking scene.

The remnants of the black-robed men regrouped within the purple mist, their bodies seemingly pulled by an invisible force as they slowly returned to their original form. These black-robed men had been beaten to pieces, but now, as if given new life, they stood up again.

Even more astonishing was that the crystal fragments on their chests automatically pieced together during this rotation, forming a complete hexagram array. This hexagram array emitted a faint light, and at the center of the array hovered half of an undestroyed entropy core. Although the core was in tatters, it still emitted powerful energy fluctuations.

At that moment, the crisp sound of disintegrating gears echoed from deep within the furnace. Three of the twelve energy conduits suddenly oozed black slime, and corrosion lines reappeared on the surface of the purified sealing chains. Lu Li's six afterimages simultaneously raised their light blades, and golden code condensed in the air to form a defensive barrier: "Not good! Fragments of the Entropy Core are contaminating the Anti-Entropy Furnace's energy circuits!"

The threads of time left behind by Lin Yue before she vanished suddenly vibrated spontaneously, weaving into a warning symbol in the void. A calico cat leaped onto the conduit, its gear collar emitting high-frequency shockwaves, attempting to shatter the clinging black slime. However, upon contact with the soundwaves, the slime instead multiplied and spread along the conduit's walls, forming a thorny, entropic network. Lu Li injected a golden code into the ground, activating the furnace's emergency repair system. A silver beam of light rose from beneath the metal floor, but the instant it touched the slime, it was stained purple-black.

"At this rate, the core will go haywire again!" The calico cat's cry was a sharp, metallic cacophony, its pupils reflecting the increasingly chaotic energy flow within the furnace core. Lu Li suddenly ripped off the data necklace from his neck—a secret treasure woven from the code left behind by the first generation of Guardians. "Use this to restart the energy center! But someone needs to enter the conduit to direct the energy!"

Before he could finish his words, an energy conduit entwined with black vines exploded. A mechanical centipede emerged from the slime, each segment embedded with the totems of destruction from various civilizations. The calico cat's gear collar automatically transformed into chain blades, leaping towards the nearest mechanical monster. The gears spun, severing three of its appendages. Lu Li's six afterimages transformed into light bullets, accurately piercing the purple crystal on the centipede's head. However, the golden code corroded into ash the instant it made contact.

Lin Yue's seventeen-colored gem suddenly erupted with a powerful light, revealing the final fragments of her memories. Lu Li and the calico cat froze in shock. On screen, the silver-armored leader thrust a badge engraved with a mirrored symbol into Lin Yue's hand. The badge now hovered above the furnace's core, strangely resonating with the surging entropic energy.

"So I've already prepared a backup plan!" Lu Li's golden code transformed into a rope that wrapped around the badge. The calico cat seized the opportunity to leap onto the core platform and use its gear collar to clamp the energy valve on the verge of collapse. The moment the badge touched the core, the entire furnace began to reverse, and silver light washed over the black slime like a tide. The mechanical centipede twisted into particles in the light, and the entropic network crumbled piece by piece.

But the crisis wasn't over. A deafening roar echoed from the direction of the mirror universe, and from the purple mist emerged a mirror image of the Entropy Colossus, its body shimmering with silver liquid metal, and a fragment of the Entropy Core embedded in its chest radiating a cold light. The voice of the remnant of the black-robed figure echoed from the void: "The true symphony of entropy begins now—"

Lu Li inserted the seventeen-colored gemstones into the furnace's control panel, and the fragments of the original time thread automatically connected to all energy conduits. The calico cat's gear collar unfolded into a hexagram array, confronting the purple formation of the mirror universe from a distance. When the mirror colossus took its first step, the entire space of the seventh universe began to fold. The anti-entropic energy of the furnace core collided with the entropy force of the mirror universe in the void, erupting an energy storm capable of tearing apart dimensions.

"This time... we must find a complete solution!" Lu Li's six afterimages re-condensed into solid form, golden codes condensing onto their surfaces like armor. The calico cat's tail lashed out with a gear blade, severing a purple chain that was about to entangle the furnace. At the center of the energy storm, seventeen-colored gems suddenly projected coordinates to a mirror universe—a purple planet enveloped in liquid time, its surface covered in the same star pattern as in Lin Yue's notebook.
