In the dead zone, strewn with the wreckage of abandoned colonial ships, the vacuum is filled only with the static hiss of a communicator🔊. Lin Ye’s magnetic boots grip the carbonized armor of the bridge, and the warmth of the gradient‑hued feathered blade in her palm seeps through her ultra‑thin protective gloves—this is no ordinary crafted artifact; it is an unfinished experimental prototype from a pre‑Third War bio‑genetic weapons workshop, each etched feather‑like pattern tuned to a specific neural resonance frequency🟣. The hollow honeycomb structure at the hilt isn’t decorative—it serves as a cultivation chamber for a symbiotic nano‑microbial community. These semi‑living microbes can consume virtually any form of energy field, even slicing through a starship’s modular armor as easily as softening butter🗡️. Lin Ye has come to search for her missing sister. Three months ago, her sister entered this ruin carrying the original blueprints for this blade, sending back only a fragmented, intermittent transmission: “It’s not a weapon—it’s…” The signal cut off abruptly, leaving behind nothing but this factory‑grade 3D printer, steadfastly holding its post. Following the parameters her sister had left, the AI completed the print and even performed a macaron‑style gradient finish on the surface, making the blade look like a creation straight out of a fairy tale🌸. Lin Ye fastens the neural interface at the back of her neck, then pushes open the sealed door welded shut at the far end of the bridge. Beyond lies a spacious chamber, where the central cultivation pod glows with a faint blue luminescence. Her sister’s neural connector remains firmly plugged into the old colonial ship’s central host interface, while the host screen scrolls with the final purpose of this feathered blade: it was never meant to kill; it is a key designed to sever “barriers”—the space of this star region has long been warped by dark energy accidentally spilling over from an experiment a century ago. Every explorer who ventures in gets folded into a non‑intersecting timeline, and only a blade forged to a precise resonance frequency can pierce that twisted spatial wall🧩. Lin Ye raises her hand, guiding the blade toward the faint, translucent folds of space looming nearby. The feathered patterns along the blade flare up in a gentle gradient, shifting from pink to blue. She can already hear her sister’s voice clearly coming from the other side of the fold—but just as the blade is about to fully cleave the barrier, the nano‑microbes in the hilt’s cultivation chamber suddenly begin to tremble violently, and a red alert surges through her neural interface⚠️—it turns out the spatial distortion was never an accident; it was a trap deliberately set by whatever lurks beyond the barrier, waiting all along for this blade to carve an opening. For a full hundred years🌌.
