The rusted bulkhead of the starship护卫舰 is splattered with pale-green Zerg bodily fluids💚, and Marine Private Kahn leans against a cooling pipe, gasping for breath. His standard-issue combat knife was already snapped in close-quarters combat; as his gaze sweeps over the scattered gear of his teammates, an ice-blue dagger catches his eye—the blade’s sharply defined edges are etched with hollow energy channels, while the geometric patterns on the hilt gleam with a low-temperature matte finish❄️. This is the Alliance’s top-secret “Ice Edge Piercer” tactical dagger, designed specifically for close-quarters space combat. Its hollow channels dissipate excess energy in the vacuum, allowing it to pierce through Zerg exoskeletons in an instant. The moment Kahn grips the hilt tightly, the dagger’s energy channels flare with a faint blue pulse⚡, and the guttural hisses of the Zerg echo behind him. He spins around abruptly, driving the blade’s tip precisely into a Zerg joint—but just as the blade sinks in, he catches a glimpse of a name engraved on the inside of the hilt: the name of the instructor who died during basic training, the man who always said, “In space, the coldest thing isn’t the vacuum—it’s the absence of your comrades.” Kahn’s knuckles turn white, and the dagger trembles slightly in his hand, as if responding to something.
