In the style of a hyper realistic fantasy movie, a retro dark green steam train comes from the blooming wildflower fields. The train adopts a brand new original design: dark green metal body, black large boiler, brass mechanical parts, circular warm yellow headlights, red metal obstacle barriers, and multiple retro green passenger carriages are connected at the rear. The most unique scene is that the smoke emitted from the train chimney is not ordinary smoke, but a huge flower cloud composed of countless real flowers. Pink, white, peach, and pale yellow flowers gush out from the chimney, constantly expanding and rolling in the sky, forming an extremely huge, fluffy, and stunning flower cloud, like a flower waterfall spanning the sky. A large number of petals and small flowers fall from the sky. The train travels through a vast sea of spring flowers, with daisies, wildflowers, and orange yellow flowers blooming on both sides of the tracks. In the distance, there are low mountains and forests. Clear blue sky, a small amount of white clouds, warm golden sunlight shining on the train and flowers from the side, and the petals presenting a semi transparent backlighting effect.
