One-Shot War Disaster Film Sequence

A detailed English prompt for Seedance 2.0 to generate a cinematic, one-take (one-shot) war disaster sequence. The scene follows a young messenger running through trenches, explosions, and debris, culminating in him reaching a ruined bell tower to fire a signal flare, providing an immersive, realistic war scale.

War disaster film feel, one continuous shot, under the gray-blue morning sky, a young messenger bursts out of an underground shelter torn apart by artillery fire, the camera closely follows him at high speed, passing through muddy trenches, burning supply trucks, shattered wooden bridges, and fleeing crowds. In the distance, shells continue to fall, dirt, wood chips, flames, and smoke columns explode continuously on both sides of the camera, soldiers and stretcher teams cross the foreground, creating a strong sense of immediacy. The protagonist climbs over a collapsed sandbag wall, slides down a slope filled with standing water, and crosses an open area covered with barbed wire and shell craters, the shockwave from explosions behind him kicking up a huge cloud of dust. Finally, he rushes to the ruins of a half-destroyed bell tower, inserts a glowing signal flare into a high device, and the camera quickly pulls up to overlook the entire burning battlefield and the advancing army in the distance, cinematic-level realistic war scale, strong rhythm, no cuts.
