Blooming
Underground

Based on the routes I frequently use, I represented air-purifying plants in the underground as orchids. Orchids serve as air-purifying flowers, with the number of flowers indicating the air quality.

Using AI, I generated a scenario where these four routes combine to create one artificial flower. In this scenario, flowers gradually grow from the soil, and butterflies flutter around them.
