Prompt (original, unmodified)
The video begins with [@Image 1] holding a camera, shaking it to shoot close-up of the astronaut's nervous eyes behind the mask. The exhaled breath fogs up the glass, and red head-up display information scrolls. Cut to another shot. Continuously track and shoot her forearm, where the mechanical plate unfolds outward, with pistons and gears meshing together. The camera moves down to her hand, and mechanical components flip out from her hand, transforming layer by layer into a futuristic, industrial-style hilt. In this continuous shot, as the hilt continues to form a glowing laser blade and ignite, the camera keeps moving down. Then, in the same continuous shot, the holographic laser blade extends in holographic segments, which are digitally processed and combined into a complete laser katana. Cut to another shot. A shaking wide-angle lens shows an industrial docking舱, with rusty gantries hidden in the fog. We hear and see a huge alien monster rushing towards her from the fog. Cut to another shot. A medium shot slowly moves down, showing her leaning forward in a dramatic martial arts sword-holding pose. Her laser blade leaves an energy trail and emits a powerful hum. The film style is sci-fi cinematic, with a low-saturation blue color palette paired with warm orange, featuring a film grain effect and handheld camera shake. Sound effects include the hum of the blade, metallic clicks, the sound of boots stepping on metal, focused breathing, deep impacts, and cinematic horror drone sounds.
