Seedance 2.0 骑手飞车逃雪崩 载具提示词

A man in his early 30s, stubble beard, wearing a black armored motorcycle suit with reflective alpine stripes and a tinted racing visor, races a superbike along a narrow mountain highway carved into a cliffside in the Swiss Alps. Snow whips across the road as the camera tracks low beside the motorcycle tires gripping the frozen asphalt. At the 2-second mark a thunderous crack echoes across the mountain — an avalanche begins collapsing above the road. A massive wall of snow pours over the cliff behind him while chunks of ice crash onto the highway. The rider accelerates through a narrow tunnel opening just as the avalanche spills across the road. Exiting the tunnel he launches off a broken section of highway, the bike airborne above a deep alpine valley before landing on the next stretch of road.
