How can there be fiery clouds in the desert? I was amazed to get up, and when I looked west, I saw that the sky seemed to be burned by flames, and what was rolling like tongues of fire was clusters of cumulus clouds hanging low like cloth bags, and these cumulus clouds were reflected red by the remnant sun, and they were faintly tumbling and rising, and at first glance, it seemed as if a raging fire was burning in the sky.

The black bull was woken up by Gu Yixin's exclamation, and a bone got up, rubbed his eyes, stared ahead and asked in surprise, "What is the fire burning?" This...... There is no hair in the desert where this bird doesn't, why is there such a big fire? As he spoke, he wanted to suddenly think of something, and turned his head with panic and anger on his face and asked me eagerly: "Old Su, it can't be a fire in the Underworld, right?!" Oh my God! Oh my God! The ...... in the dungeon"

I interrupted Hei Niu's words: "You are virtuous, and you are not afraid of Miss Gu and Sixth Master laughing at them!" I looked down into the distance again and said with certainty, "It's a fiery cloud!" You have forgotten, we have learned a text called "Burning Clouds" in our primary school textbook, which says that the setting sun turns the clouds on the horizon red, and the clouds turn into strange shapes......"

"Oh~! I remembered whether that text said that the clouds in the sky were like roast chickens for a while, and like roast geese for a while! The black bull turned to a serious and said: "But is the fire cloud burning in front of me a little fierce, why do I see the smoke rising?" ”

As he spoke, everyone else woke up, and the subconscious fright made everyone regain their spirits, and they all got up one after another, all looking into the distance in fear. Only Ah Biao was lying on the ground with a red face, and everyone thought he was sleepy and didn't wake up.

This cloud layer is a typical cumulonimbus cloud, with clusters of smoke like gatherings, tumbling and surging under the action of the light wind, and then reflected by the remnant sun, a fiery red. Nine times out of ten, people who don't understand meteorology will mistake it for a burning smoke and fire.

"Don't be afraid, everyone, it's just a burning cloud! An ordinary natural phenomenon! I added with some joy: "Moreover, the appearance of this fiery cumulonimbus cloud is like a miracle for us!" ”

"It's a disaster coming from heaven! We can't escape! Can't escape! The Uyghur guide said in shock, and once again his head was like garlic, and he kept kneeling to the west, this time kneeling with great intensity, almost burying half of his face in the sand.

Gu Yixin ignored the guide and asked me, "Miracles from the sky?" Lao Su, are you saying that we can count on this rain to survive? ”

"It's not." Before I could explain, the black cow swallowed his saliva and couldn't wait to ask, "It's raining?" Miss Gu, you said it would rain on this red cloud? Unreliable? ”

"Of course, this is a cumulonimbus cloud, formed by the condensation of a large amount of water vapor, as long as there is a heavy cumulonimbus cloud, later, there will be rain under the clouds!" Gu Yixin explained a little and continued to ask me: "Lao Su, did you think of something?" ”

I looked at the surging clouds and excitedly explained, "There are two prerequisites for the formation of heavy cumulonimbus clouds, one is a strong water vapor and the other is strong air convection. The water vapor rises into the air and cools down to form clouds. The sea of sand is vast and dry, except for a surging cumulonimbus cloud, which shows that the place under the clouds must be full of water vapor, and in addition, in the topography, there must be a certain gap with other places! ”

"Oasis?!" Gu Yixin and the sixth master said in unison!

"That's right! If that's right, the oasis where the Hades is buried is just below the cumulonimbus clouds! After I finished speaking, I looked around at the crowd, and the tiredness and gloom on everyone's faces were swept away, and they all cheered and excited.

"Holy! Finally, the fuck is coming! The black bull grabbed his backpack, ran forward with his legs open, and beckoned: "What are you waiting for, hurry up and run!" Let's talk about it first, the treasures in the dungeon, first come, first served! ”
