)峡谷上空的电影级火车场景

A lone figure stands on a rocky cliff in the left foreground, facing a wide alpine canyon. The figure is still, wearing a dark coat that flutters in strong mountain wind. In the distance, directly ahead, two opposing cliffs span the width of the scene. Snow-covered mountain peaks rise beyond them, partially shrouded in clouds. A sleek, futuristic bullet train emerges from a tunnel in the left cliff across the canyon, moving horizontally across empty space. There is no bridge or track beneath it. As the train moves forward, glowing blue-white track begins to form beneath it in real time. The rails assemble from particles and light, locking into place just before the train rolls over each segment. Mist swirls around each new section as it materializes. The camera begins behind and slightly above the figure on the cliff, then rises steadily into a wide aerial shot. The full landscape becomes visible: the figure still standing in the left foreground, the train speeding across the gap on the forming track, and far below, a rushing river cutting through the base of the canyon. Snow drifts through the air, wind stirs the clouds, and the glowing bridge continues forming seamlessly across the abyss.
