Feng Yun raised his head and looked at the seemingly endless heavy snow. He had a deeper understanding of the destructive power of the porcelain tube maze when he burst out, and once again exceeded his expectations.

He did not expect that the white mist produced when it erupted had the ability to influence the celestial phenomena.

The origin of this heavy snowfall is very clear. It should be that the white mist rushed into the sky under the restraint of the firefighter he controlled, and then the cold air it contained contacted the water vapor in the air, causing them to condense and gather together. , Formed a snowflake.

However, the impact of the cold contained in the white mist is not limitless after all, so the heavy snow did not last for too long. After a while, it stopped.

Even so, when the snow stopped completely and the sun reappeared in people's vision, the snow on the ground still disappeared from the foot.

Feng Bei was so overwhelmed by the sudden appearance of heavy snow, until the snow stopped completely, she did not fully react until she grabbed a handful of snow from the top of her head, and the cold touch from her palm convinced her completely. What I saw was indeed snow.

"Brother Yun, this snow...what's the matter with this snow? How can it snow now?"

Feng Bei shook his hand, shook off the snow, and asked Feng Yun.

She will seek answers from Fengyun, but it is not that she has realized that he is the instigator of this totally out-of-season heavy snowfall. It is entirely because of the image that Fengyun's usual behavior has erected in her heart.

Fengyun's usual behaviors, whether it was the inventions and creations he made, or the solutions to some difficult problems, left her with a learned impression.

It is the end of summer and early autumn, and it will never snow. At least since her birth, she has never heard of snow in this season, which is obviously unreasonable.

However, the heavy snowfall happened. This is an indisputable fact. She couldn't understand it, so she instinctively looked for someone who could explain to her, that is Fengyun.

"This one……"

Feng Yun did not immediately give an explanation. It was not that he was unwilling to explain, but that he considered that he was facing a primitive person. Even because of his existence, Feng Bei's knowledge is much better than ordinary primitive people, but he must think Speaking clearly in a language that she can understand is still quite difficult.

He needs to think about what to say.

"Brother Yun, don't you know?"

Feng Bei misunderstood Feng Yun and couldn't help showing disappointment.

"I know."

Feng Yun thought about it, and decided to explain the cause of the heavy snow with Feng Bei, because he realized that even if Feng Bei didn't ask, others would ask.

Among these people, there must be Mu Qiuxia. With her old hotness, it will not be easy to fool her with words.

Instead of this, it is better to clarify the problem. Although it is not easy to make it clear, it is not impossible.

"you know?"

Feng Bei's eyes lit up, and he urged in a hurry, "Brother Yun, tell me what is going on?"

"The reason is very simple. The reason why this snow appeared is entirely because of the white mist."

"Because of the fog? I don't understand."

Feng Bei listened to Feng Yun's words and shook his head repeatedly.

Feng Yun was not surprised by her performance at all. If he said that, she would understand and he would feel abnormal.

"Bei, have you seen freezing?"

"Of course I have seen it. In winter, not only will the rivers and lakes freeze, but the water in the tanks and buckets will also freeze, but what does this have to do with the snow now?"

"Then tell me why it freezes in winter?"

"I know this because of the cold."

"That's the point. Although it's not winter, the white mist is very cold. Under its influence, there will be astronomical phenomena that only appear in winter."

"But Brother Yun, what you said was freezing, I asked about snowing."

"This is not a contradiction. Freezing and snowing are actually the same thing."

"It's the same thing? Why didn't I see that snow and ice are obviously two different things."

Feng Bei was not convinced by Feng Yun, or more precisely, she had not figured out the similarities between snow and ice.

"Ice is formed by condensation of water, and snow is also formed by condensation of water. They are naturally the same thing."

"Snow is also made by condensation of water? But it clearly comes down from the sky, how can there be water in the sky? If there is water, why doesn't it fall?"

"Who said that there is no water in the sky? Bei, then tell me what rain is? Isn't it just falling from the sky?"

"This one……"

This time it was Fengbei's turn to be speechless.

"There is water in the sky, but the naked eye does not agree to see it. This water, no, it should be said that after encountering the cold, the water vapor will condense, gather together, form snow, and fall on the ground."

"Brother Yun, why is there water in the sky, and you can't see it?"

Feng Bei should have accepted Feng Yun's rhetoric, stopped entangled in the snow, and started to change the subject.

"Bei, have you dried your clothes?"

"It's been aired."

"Wet clothes contain a lot of water, but after a period of time, they dry out. This is because the water contained in them evaporates and becomes a state similar to the breath we exhale. When they become gaseous, they become very light and can fly high in the air."

Having said that, Fengyun paused for a while, as if he wanted to give Feng Bei time to digest it, and then continued: "In fact, the water vapor rises to the sky, and we can also see it. That is the clouds. They are gathered by the water vapor. It's done."

"That's not right. Brother Yun, don't you say that water vapor is invisible? If clouds are really formed by gathering them, why can they be seen, and sometimes the clouds are still black?"

"This one……"

Feng Yun couldn't help but smiled bitterly in his heart. Fortunately, he was prepared for this situation, and soon found the explanation: "The wings of a dragonfly are thin and transparent. It is difficult to see if you look at it, but When many dragonfly wings are put together, is it easy to see them, or even find that they have become opaque?"

"Oh, I see. Clouds can be seen by us because there is a lot of water vapor that makes up them. Brother Yun, isn't that true?"

Feng Bei showed a suddenly realized expression.

"Yes, yes, yes. Completely correct."

Feng Yun saw that Feng Bei finally understood it under his patient explanation, and suddenly felt relieved, because he finally didn't have to worry that someone would ask him about this question again.

In the process of explaining with Feng Bei, the clansmen of the two tribes of Baicao and Huojiao, headed by Mu Qiuxia and Feng Lei, who stayed in Shuang Lengquan gathered together, and they heard what he and Feng Bei said.
