Thick ink-colored clouds squeezed the sky

Before it rained, the clear sky suddenly turned into a big black curtain, covering the entire sky, even the most dazzling sun disappeared without a trace, the clouds in the sky were getting lower and lower, it was about to rain, the pedestrians on the road dodged in time, leaving me alone on the street, I had to quickly hide under the eaves to avoid the rain, hoping that the rain would stop quickly.
