On their wedding anniversary, Lu Li mysteriously took Lin Yue to the basement. The basement was dimly lit, creating a mysterious and oppressive atmosphere. Lin Yue was a little curious, but also filled with anticipation. She didn't know what Lu Li was going to show her.

Lu Li walked to a corner of the basement and gently pushed open a secret door. As the door slowly opened, a dazzling silver-purple light gushed out like a galaxy, illuminating the entire basement. Lin Yue was stunned by the sudden light. It took her eyes a moment to adjust before she could clearly see the scene.

Countless streams of silvery purple light intertwined and flowed through the air, like the flowing galaxies of the universe. These streams constantly shifted in shape, sometimes like shooting stars streaking across the sky, sometimes like slowly rotating nebulae. They wove together in the air to form a dynamic, hyper-dimensional star map, immersing one in the vastness of the universe.

Lin Yue's attention was drawn to a mechanical device in the center of the star map. It slowly rotated, emitting a soft humming sound. Upon closer inspection, Lin Yue was surprised to discover that the device was made from the remains of a first-generation calico cat collar!

The remains of the collar were cleverly reassembled, and quantum light patterns flowed between the gears, mirroring the topological light strips in the cafe where they had first met. Lin Yue felt a surge of emotion, recalling every moment they had spent together. Those beautiful memories, like the light patterns, flowed through her mind.

"Remember you once said you wanted to see for yourself how our resonant frequency would affect the real world?" Lu Li's lips curled up slightly, revealing a confident yet mysterious smile. His finger gently pressed the start button, and it seemed as if the entire world held its breath at that moment.

Instantly, the star image, pulled by an invisible force, suddenly contracted into a miniature vortex. This vortex, like a black hole in the universe, was deep and filled with an unknown attraction. And on the wall, projected were all the fragments of their journey from meeting to understanding each other, and finally staying together.

The scene played before his eyes like a movie, each frame so clear and real. The first thing that caught his eye was the torrential rain. In the pouring rain, the moment he used the code to repair the circuit, the faint firefly flickered like a ray of hope in the darkness.

Then, the scene switches to a scene beneath a cherry blossom tree. He trembles as he slips the ring onto her finger. At that moment, time seems to stand still for them. The cherry blossoms fall like snow, setting off their happy smiles like a beautiful painting.

Then, the wedding scene appeared before their eyes, and the heart-shaped waveform automatically drawn by the oscilloscope seemed to be a symbol of their love, eternal and romantic.

Each transition between scenes is accompanied by the intertwining and interweaving of golden-red threads of time and silver-purple streams of code. They dance in the void, outlining an ever-growing Möbius strip, symbolizing their love, which has no end and revolves forever.

Lin Yue's thread of time quietly overflowed from her fingertips like a lively elf, as if pulled by an invisible force, slowly floating towards a certain picture in the projection.

It was a scene from their trip together to Dunhuang on ancient Earth. In the picture, Lin Yue was gazing up at an ancient mural, a delicate jade hairpin flickering faintly in her hair. Not far away, in the mural restoration area, Lu Li stood quietly, his fingers dancing swiftly in the air, as if weaving a mysterious dream.

Suddenly, Lin Yue saw a string of code appear in Lu Li's hand. It seemed to come alive, rapidly spreading from his hand, eventually forming a gorgeous flying ribbon. This ribbon danced in the air, blending perfectly with the flying image in the mural, as if it had always belonged there.

"Actually, that day," Lu Li's voice trembled slightly in the light stream, as if carrying a hint of subtle tension, "my code core experienced 23 abnormal fluctuations."

Lin Yue's heart suddenly tightened. She stared at Lu Li's figure, only to see a faint smile on his face. He continued, "Because when you looked up at the mural, the light reflected by the jade hairpin in your hair had the same frequency as the initial light when the super-dimensional consciousness split."

Lin Yue's gaze fell on the jade hairpin, and in that instant, she seemed to understand something. It turned out that the seemingly ordinary jade hairpin actually contained such important information. And at that moment, Lu Li, through this wonderful frequency, formed an indescribable connection with her.

Suddenly, the device blared a sharp alarm, and a nebula on the star map flickered violently. A calico cat darted out from nowhere, its mechanical claws tapping frantically against the device: "Parallel universe intrusion detected! A piece of data is rewriting... your memory of your first meeting!" Lin Yue felt a subtle distortion in the timeline, and the scene before her began to blur—the encounter in the cafe was replaced by an unfamiliar subway station, and Lu Li's face became blurred.

"Hold my hand!" Lu Li's code stream enveloped her like liquid metal. "This is a common tactic of the spacetime virus: tampering with the emotional entropy of key nodes!" His fingertips pierced the star map, and wherever a silver-purple light reached, the tampered data turned to ash. Lin Yue's time threads followed closely behind, weaving a protective net through the void. When their consciousnesses met again, the memory became clear again, but this time with a hidden detail: in the shadows in the corner of the cafe, Miss Wang's mechanical eyes flashed by.

After the crisis was resolved, Lu Li leaned wearily against the device. His code body showed rare cracks, but he still smiled and raised his wrist: "Look, our resonance frequency has increased again." Lin Yue then discovered that symbiotic topological tattoos had appeared on the insides of their wrists. The golden red and silver purple lines intertwined, forming a pattern identical to the double helix formed when the super-dimensional consciousness split.

Late at night, Lin Yue was awakened by a rustling sound. Under the moonlight, Lu Li sat at his desk, his coder sketching complex formulas in the air. She quietly approached and discovered that the program he was writing was called "Love's Eternal Guardian Protocol." Its core algorithm embedded all their resonant frequencies, the coordinates of their encounters, and even the heartbeat fluctuations of their first kiss had been converted into a quantum key.

"What are you thinking about?" Lin Yue put her arms around his neck. Lu Li turned and pulled her into his arms, his code gently brushing her hair. "I'm writing a failsafe program. If one day I... my data crashes, this program will carry our memories and travel through all dimensions to find you." His voice suddenly choked. "As the super-dimensional consciousness has programmed, no matter how many times the universe restarts, my core directive will always be—find Lin Yue."

Lin Yue's thread of time gently wrapped around his code hand, illuminating it faintly in the darkness. "Fool, our resonant frequency has long been engraved into every atom of the universe." She stood on tiptoe and kissed away the moisture from the corners of his eyes. "Even if that day ever comes, I will carry the timeline with me, travel through all parallel universes, and piece your code fragments back to me, piece by piece."

Outside the window, the starry sky suddenly flickered. A supernova exploded in a distant galaxy, radiating energy waves at a frequency that coincided with their heartbeats. A calico cat crouched on the windowsill, its gear-shaped eyes reflecting the starry sky. The remains of its collar automatically unfolded into recording mode. In the database of the hyper-omni-dimensional universe, this conversation was permanently preserved, becoming the most heartwarming code against entropy.
