骑行者逃离坍塌中的古城

Create a 15-second ultra-photorealistic Hollywood urban disaster sequence captured in ONE continuous physically coherent FPV drone shot.

LOCATION: A beautiful historic European city with narrow cobblestone streets, colorful old buildings, outdoor cafés, stone bridges, tram lines, and a large central cathedral.

CHARACTER: A young woman wearing a blue denim jacket, white sneakers, black helmet, and a small brown backpack, riding a realistic silver city bicycle.

0–3 SEC — THE FIRST CRACK: Begin inches above the cobblestones, tracking the bicycle moving quickly through a narrow old-city street. Coffee cups rattle on café tables. The pavement suddenly splits behind the cyclist, sending stones bouncing across the road.

3–6 SEC — THE CITY SINKS: A gigantic underground cavity collapses beneath the plaza behind her. Entire café terraces, streetlights, parked cars, and sections of roadway slide into an expanding sinkhole. The camera swings alongside the cyclist as dust pours between the buildings.

6–9 SEC — THE FALLING BELL TOWER: The cathedral bell tower begins leaning as its foundations fail. Huge masonry blocks crash into the plaza behind the bicycle. The cyclist swerves into a narrow side street while the tower collapses across the intersection she just escaped.

9–12 SEC — THE BRIDGE ESCAPE: She pedals onto a centuries-old stone bridge spanning a river. The approaching ground rupture reaches the bridge's near-side approach. Stone paving fractures behind her, and part of the riverbank collapses into the water.

12–15 SEC — THE FINAL REVEAL: The cyclist reaches the far bank as the camera cranes upward and backward. Reveal the enormous historic city center sinking into a vast expanding crater, dust clouds rising above rooftops, and the lone cyclist escaping along the river road.

CRITICAL: Exactly one uninterrupted shot. One connected street route. Consistent character and bicycle. Realistic pedaling cadence, wheel-ground contact, natural steering, gravity-driven building collapse, physically coherent sinkhole propagation, persistent debris and architecture. No cuts, no teleportation, no impossible jumps, no object morphing.

OUTPUT: 15 seconds, IMAX-scale Hollywood photorealism, 4K, 16:9, 24fps, natural daylight, cinematic motion blur, detailed architecture, no text, no slow motion, no logos.
