Now the sky is also covered with more and more dark red clouds. Yunlan climbed out of every cave, raised their strange big heads, elongated their slender bodies, and threw their gray manes into the wind, revealing big and dirty teeth; Clouds and mist appeared in droves. Clouds from the north: black and big, but messy and ragged, overlapping and flourishing, like countless blown forests, with deep gaps between them, and huge stripes like light green ice scattered on them. These red clouds rush forward with wild power and make a dull roar. Those from the west are slowly advancing clouds: lead-like colors, huge swollen bodies, and some places shine like flames; Those clouds rolled in turn, becoming more and more firm in the long journey, similar to flocks of big birds. Coming from the east is a flat rust-colored steam mass, monotonous and monotonous, just like carrion stained with colorful blood on the wound, which makes people dare not face it squarely. There are also energetic clouds floating from the south. Their colors are black and red, which reminds people of pieces of peat. Although they are dark and lifeless, there seem to be evil insects hidden inside. Clouds are also floating high, as if falling from the extinguished pale sun ball. They either form a hazy and dim jack-o'-lantern, or they are mixed with colorful, like dying embers. All these clouds and mist swarmed in and piled up into mountains, flooding the whole sky with a turbid black torrent.
