Small robot harvesting soybeans in a calm countryside field

A wide cinematic shot of a peaceful countryside field at golden hour. A small robot inspired by WALL-E style, slightly worn, quietly harvesting soybeans with gentle, repetitive movements. The atmosphere is calm, wind softly moving the crops. In the far background, a massive explosion slowly rises, forming a clear mushroom cloud, resembling a nuclear bomb. The explosion is distant, almost silent, glowing softly against the horizon. The robot does not react at all, continuing its task with serene indifference. Camera slowly pushes forward toward the robot. Contrast between calm foreground and catastrophic background. Hyper-realistic lighting, cinematic depth of field, emotional contrast.
