A flaming arrow races through smoke and troops before striking a shield as two battle lines collide — cinematic action video

Prompt

15-second cinematic battle shot locked behind a single flaming arrow. A commander releases the arrow from a hilltop at sunset, and the camera instantly snaps behind it in extreme high-speed pursuit. The arrow cuts through smoke, over cavalry, between elephant armor plates, under falling debris from a siege tower, and through crossing volleys of spears and banners. The battlefield blurs into streaks while the arrow remains sharp. In the final seconds, it crashes into a shield at the exact moment two infantry lines collide, dust and splinters exploding across frame. Impossible guided-flight camera, epic war scale, perfect action readability.
