Seedance 2.5 Courier Carrying Medical Supplies Prompt

A cinematic sequence with four precise shots. A courier carrying sealed medical supplies enters a forest of white-barked trees as an unnatural storm approaches. Shot 1: a steady camera follows behind the courier; the forest ahead is green, while a narrow band of rainfall moves between the trunks like a traveling wall. Shot 2: macro close-up of rain striking a fern; its leaves yellow, curl, and crumble within seconds, while an abandoned metal sign rapidly corrodes beside it. Shot 3: the courier notices the approaching rain and runs toward a concrete drainage tunnel, cargo rocking with physically believable inertia. Shot 4: from inside the tunnel, the camera looks past the exhausted courier toward the forest; trees touched by the storm collapse into pale dust, leaving an open landscape under the same unchanged sky. Photorealistic environmental transformation, tactile protective clothing, restrained visual effects, muted green fading into silver and ash. Sound: rain, snapping branches, mechanical breathing filters, an unresolved cello note. Preserve the courier's appearance and equipment across every cut. No readable signage, logos, or interface.
