摩托车穿越废墟天桥

high-altitude ruined skybridges connecting tower husks, dust clouds far below. The motorbike rider blasts along narrow switchback curves on fractured skybridge segments, leaning aggressively. Camera starts far wide to establish dizzying scale, then dives into a close tracking chase that mirrors each curve, then pulls out again to show the next bridge fragment. Ultra-detailed ruins: twisted steel frames, torn cables whipping in wind, cracked tiles, broken antennas. The route changes as a bridge section collapses behind, forcing a sharp new curve onto a lower bridge.
