15秒电影级照片般写实的科幻动作短片，16:9。

15-second cinematic photorealistic science-fiction action short, 16:9. A gigantic futuristic city travels through deep space inside an enormous asteroid storm. Thousands of spacecraft fly alongside it, actively manipulating the asteroids into a constantly moving defensive shield. Suddenly an enemy fleet attacks. Hundreds of fighters dive into the asteroid field. The city accelerates. Asteroids slam into attacking ships. Defensive spacecraft race between enormous rocks, pushing them into new trajectories. A massive enemy warship breaks through the asteroid shield and fires directly at the city. The entire city suddenly changes direction. The asteroid field moves with it. Millions of rocks swing into formation around the city like a gigantic mechanical organism. The attacking warship realizes too late that the asteroid field itself is the city's weapon. A colossal impact fills the screen. End on the city disappearing into the moving storm. Photorealistic hard science fiction, spectacular asteroid environments, relentless combat, massive moving structures, fast camera movement, detailed spacecraft, huge scale, cinematic action, no text, no logos, no anime, no cartoon.
