At the edge of the black hole formed by the collapse of liquid time, Lu Li's six afterimages teetered under the powerful gravitational pull, seemingly ready to disintegrate at any moment. However, he didn't give up. Instead, he tightly grasped the gear fragment left by the calico cat and embedded it into the golden code core without hesitation.

At the moment the gear fragments perfectly meshed with the core, the data stream suddenly shone with images of the first generation of Guardians in battle. These silver-armored warriors had once faced endless darkness and destruction in the birthplace of the Entropy Demon, fearlessly. They had used their lives to weave a narrative filter against entropy, safeguarding the order and balance of this world.

Lu Li gazed at those brave and fearless figures, a strong sense of mission welling up in his heart. He muttered to himself, "Reverse the root of the narrative..." These words echoed in his mind like a mantra.

His gaze gradually locked onto the entropic core that was constantly expanding within the chest of the fused mechanical lifeform. Like a bottomless black hole, the core was madly devouring the spacetime fabric of the purple planet, engulfing everything in it.

Deep within the core, the fragments of Lin Yue's consciousness lingered like a candle in the wind, struggling against the torrent of entropic energy. This powerful force constantly assaulted her being, attempting to devour her completely.

However, at this critical moment of life and death, Lin Yue's original time thread suddenly resonated strongly with the mysterious seventeen-colored gem. This resonance was like lightning that split the night sky, instantly outlining a tiny light network in the chaos.

Although fragile, this light net was like a ray of life, providing a respite for the fragments of Lin Yue's consciousness. Whenever the mechanical lifeforms attacked, the residual images of Lin Yue's memories would overflow from the spatial cracks.

These afterimages flashed by like movie frames in a vortex of entropy. There were the quiet afternoons she spent mapping the stars in the garden of liquid time, the sun streaming down her as she focused on depicting the mysteries of the universe. There were also moments she fought alongside Lu Li and the calico cat, their figures weaving in and out of the hail of bullets, their tacit understanding ensuring their unwavering success.

However, these beautiful images were like shooting stars, briefly streaking through the vortex of entropy before being instantly shredded by the black vines. They dissipated in the darkness, as if they had never existed.

At the edge of the universe, twelve suspended silver altars suddenly lit up. The remnants of consciousness from the original Guardians awoke from their armor, transforming their weapons into chains of light, piercing the edge of the black hole. "Outsider! Take this key!" an old voice boomed through Lu Li's mind. A blade of light, engraved with seventeen colors, pierced through space and time, landing precisely in his palm. The moment the blade made contact with the golden code, Lu Li's six afterimages merged into a solid form, and the same defensive totems as those on the altars emerged from the surface of his armor.

The mechanical lifeform's massive claws tore through space, attacking. Lu Li swung his light blade to meet it. The instant blades collided with metal, countless tiny cracks appeared in space. From each crack, black vines sprouted, attempting to entwine his body. "These vines are devouring the narrative energy generated by this battle!" Lu Li's pupils constricted. The golden code transformed into nanorobots, burrowing into the cracks, only to discover that within the vines flowed data identical to his own.

Elsewhere, a calico cat, swallowed by a rift in spacetime, fell into a forest of gears. The trees here were composed of giant clockwork, their leaves like gears engraved with entropy spells. Its broken collar suddenly resonated, guiding it to a suspended clock tower. Inside, an ancient computer composed of gears was calculating entropy equations, while images of Lin Yue trapped flashed across the screen. "So this is... the narrative center of the mirror universe!" The calico cat's tail lashed out with a gear blade, severing the black vines entwined with the computer.

As the computer rebooted, the forest of gears began to spin in reverse. The calico cat saw that each gear blade recorded the timeline of a certain universe—the mechanical heart of the steampunk universe stopped beating in reverse, and Cybertron's code python was transformed into a data torrent. It immediately transmitted the clock tower's coordinates to Lu Li via quantum fluctuations. But at that moment, a giant hand made of gears suddenly grabbed the clock tower and dragged it deeper into the folds of space-time.

On the main battlefield, Lu Li's light blade finally sliced ​​through the mechanical lifeform's defenses. The moment the blade touched the core of entropy, the fragments of Lin Yue's consciousness erupted with intense light. Fragments of seventeen-colored gems flew from the core, merging with Lu Li's light blade, forming a longsword shimmering with the aura of time. "Use this sword... sever the narrative anchor of entropy!" Lin Yue's voice, mingled with the data stream, flowed across the blade.

Lu Li raised his sword high and plunged it into the core. Space and time around the blade began to flow in reverse. The mechanical lifeform roared in pain, its body gradually disintegrating into countless fragments of memory: images of the remnants of the Black Robes chanting at the altar, the corruption of the First Guardians, and... the birth of the Entropy Demon, tearing apart the cosmic membrane. These images distorted and reorganized in the blade's light, forming a space-time tunnel leading into the past.

"So the source of entropy... is at the very beginning of the universe!" Lu Li's golden code frantically decoded the information in the tunnel. He saw that in the aftermath of the Big Bang, a mysterious civilization, seeking to control time, used forbidden technology to create an entropy core, but inadvertently unleashed the all-consuming demon of entropy. And now, mechanical lifeforms were absorbing these fragments of history, attempting to make entropy the sole law of the universe.

At the critical moment, the calico cat's quantum signal suddenly connected. "Lu Li! Activate the clock tower's narrative rewind function!" Its voice echoed with the roar of turning gears. Lu Li immediately injected the golden code into his sword, and the light bursting from the sword's tip resonated with the clock tower. The entire mirror universe began to rotate in reverse, the mechanical lifeform's body gradually becoming transparent, and the energy at the core of the entropy was extracted into a pure narrative flow.

But just as its core was about to collapse, the remaining consciousness of the Entropic Shadow Colossus suddenly awakened. It manipulated the mechanical lifeforms to self-destruct, releasing enough energy to destroy ten galaxies. Lu Li channeled his final strength into his longsword, connecting it with the First Guardian's light chain, weaving a vast narrative filter at the center of the explosion. The fragments of Lin Yue's consciousness transformed into seventeen-colored threads, entwining the filter in a final confrontation with the entropic energy.

"Together, let's rewrite the ending!" The voices of Lu Li, Lin Yue, and the calico cat intertwined across space and time. The filter began to absorb the entropy energy, transforming it into a primordial narrative for rebuilding the universe. As the aftermath of the explosion dissipated, a new planet, composed of liquid time and golden code, slowly took shape at the core of the mirror universe. On its surface, a familiar figure approached, treading on the starlight...
