An unmanned aerial vehicle hovers in the air above a green field at sunset. Its fuselage is designed in the shape of a dark blue UFO, with a domed cockpit at the top, which is covered with star patterns. Several twinkling blue stars surround it. The original four propellers of the unmanned aerial vehicle are retained at the bottom, and the propeller blades are in dark blue and white stripes. It presents a visual effect of the integration of science fiction and reality. 8k ultra-high definition,
