A passage describing a dark cloud

1. In the sky, dark clouds are rolling and rushing in from all directions, piling up in piles and getting denser and denser, like hordes pressing on the roof. The distant mountains are gray and submerged by dark clouds on the horizon, and the low sky seems to indicate that a rainstorm is coming.

Just now, everything was still enjoying the afterglow of sunset. The wind blew, the light suddenly dimmed, and the rolling dark clouds were like wild horses. It is also like an evil soul using a big net that devours human beings. The earth is shrouded in darkness.

3. Yunlan climbed out of every cave, raised their strange big heads, elongated their slender bodies, threw their gray manes into the wind, exposed their big, dirty teeth and swarmed in. Clouds from the north are black and big, chaotic and broken, overlapping each other, causing trouble, like countless blown down Woods. These red clouds rush forward with wild power and make a dull roar.
