潜水者发现海底王国

A cinematic 15-second fantasy adventure following a lone diver descending through crystalline blue-green water toward a vast medieval kingdom preserved beneath the sea. Shafts of surface light cut down through drifting silt as the diver passes colossal submerged statues still standing at their posts. Ancient bronze mechanisms stir to life at their approach, forcing seawater outward and opening a shimmering air-filled dome around the city — streets, towers, and lantern-lit markets suddenly dry and breathing after centuries. The diver pulls off their mask, gasping, as schools of luminous fish stream overhead along the curved wall of water and vast whale-like guardians glide silently past the dome.
