Song Qingshu was taken aback: "What do I owe you?"
The woman in the yellow shirt opened her mouth, but she didn't say anything. Instead, she blushed slightly, and said after a long time, "You still tell me how you managed to call the wind and rain last night?"
Only then did Song Qingshu remember that she even kissed himself last night for the answer, and covered the place where she kissed last night, and couldn't help giggling.
"Don't laugh!" The woman in yellow shirt couldn't help being a little annoyed.
"Okay, okay, don't smile, don't laugh," Song Qingshu said hastily when he saw that the woman in front of him was turning into an angry female leopard, "Since I have received the reward, I will naturally not deny it."
The woman in yellow shirt's expression softened slightly, but when she thought of the reward he was talking about, she felt uncomfortable for a while.
Song Qingshu cleared his throat, and then began to explain: "Do you know the principle of rain?"
The woman in the yellow shirt frowned slightly and shook her head. Although she knew that Thunder God and Lightning Mother were just myths and legends, she really didn't know how it rained.
Song Qingshu explained with a smile: "The sun shines on the earth, water vapor rises from the surface of oceans and lakes and becomes part of the air, and when it encounters cold air at high altitude, it condenses into small water droplets. These small water droplets are so small that the naked eye can barely see them." Can't tell. They're small and light, held up in the air by updrafts in the air, and come together to form clouds..."
"Clouds are formed by water vapor?" The yellow-shirted woman couldn't help asking, she was confused when she heard the words of updraft and so on. You must know that people in this world always imagine clouds as a kind of mysterious thing, and they tend to be confused with them. Connecting various myths and legends, how do you know that clouds are actually ordinary water vapor
"Of course, I've been in the clouds." Song Qingshu couldn't help thinking of the scene of crossing the clouds with Dongfang Muxue in Heimuya, and a trace of tenderness appeared on his face.
The woman in the yellow shirt subconsciously felt that he was bragging. After all, in common sense, only gods and gods can soar through the clouds, but when she thought of the scene of him going up to the sky last night, she couldn't help but sigh: "That's right, what did you do yesterday? It is not difficult to go up to the clouds with this kind of light work."
After imagining the scene described by the other party, she suddenly frowned and said, "According to what you said, the clouds are full of water droplets, so why don't the water droplets fall?"
"Didn't I just say that those small water droplets are so small that you can't even see them," Song Qingshu explained, "The raindrops you usually see are more than 100,000 times larger than those small water droplets."
"One million times?" The yellow shirt woman's face changed, she really couldn't imagine what a million times is.
Song Qingshu explained to her: "Those small water droplets are also called cloud droplets. They mainly rely on continuously absorbing the water vapor around the cloud to condense and desublimate themselves... Uh, what is desublimation? You can imagine it as growing yourself... If The water vapor energy source in the cloud body is continuously supplied and replenished, so that the surface of the cloud droplet is often in a supersaturated state, then this condensation process will continue, and the cloud droplet will continue to grow."
"When the cloud droplets grow to a certain extent, due to the continuous increase in volume and weight of the large cloud droplets, they can not only catch up with the slower small cloud droplets in the process of descending, but also 'swallow' more small cloud droplets. When the big cloud drop grows bigger and bigger, and finally the air can no longer support it, it will fall straight from the cloud to the ground, and it will become the common rainwater and finally become a raindrop.”
The woman in yellow shirt nodded half-understood, and thanks to her extensive reading of poetry and books, coupled with her cleverness, although there were still many details that she didn't understand, she still understood the general principle.
"But..." The girl in yellow suddenly thought of something, and looked at Song Qingshu with burning eyes, "According to what you said, the rain can only fall when the cloud droplets are big enough, but how did you control the timing of the rain so coincidentally yesterday?"
"It's all thanks to your help." Song Qingshu said with a smile.
"Me?" The woman in the yellow shirt blushed, "How can I help you?" She thought to herself that she didn't even know the principle of rain, so how could she help you.
"Have you forgotten the bag of things you found for me yesterday?" Song Qingshu's eyes were full of smiles.
"That bag of salt?" The woman in the yellow shirt opened her moist red lips wide, "Is that bag of salt used for rain?" When she heard the other party's request yesterday, she was at a loss, but out of trust, she still stood up for him. I found it, and after experiencing the shock of his flying into the sky and calling the wind and rain, this trivial matter was quickly forgotten, and I never thought it would be related to the rain.
"Otherwise, should I eat it?" Song Qingshu smiled and continued to explain, "Just now I have talked about how rainfall is formed, but there is still a key issue that I haven't said, that is how water vapor forms small water droplets in the first place .”
"How did it come about?" The woman in yellow shirt was stunned at this moment, and she asked like a conditioned reflex.
Song Qingshu replied: "Water vapor must accumulate around fine particles such as dust to form water droplets or ice crystals. These particles are so small that the naked eye cannot detect them at all, but without these particles, although there is enough water vapor in the air, it is impossible to form water droplets or ice crystals. Make a drop of rain."
"So you use salt to replace those fine dust?" The yellow-clothed woman Bingxue was smart, and quickly drew inferences from one instance to another.
"That's right," Song Qingshu nodded, "When I reached above the cloud layer, I used my power to spread the fine salt evenly. The water vapor in the cloud layer had condensation nuclei, and the speed of rainfall was greatly shortened..."
While Song Qingshu was talking, he suddenly found that the woman in yellow was staring at him blankly, and couldn't help laughing: "Are there any flowers on my face?"
The woman in the yellow shirt blushed, shook her head hastily, and said, "I didn't know what it means to be a pedantic celestial being, but today I finally see it. You are not only world-class in martial arts, but you are also so knowledgeable..."
"These abilities are not worth mentioning," Song Qingshu said solemnly, "Actually, my biggest advantage is that I am handsome and handsome."
The girl in the yellow shirt originally looked at him with admiration, thinking that he would say something that would shock the past and the present, but she didn't expect such an answer, so she couldn't help but blushed and spat: "You are always like this! Not serious~"
Song Qingshu spread his hands: "Look at your face of seeking knowledge just now, if I continue to be serious, you will worship me as a teacher, I don't want you to call me master."
"Then what do you want me to call you?" The yellow-shirted woman opened her mouth, but she still didn't say the words, with a slight smile on her face: "Actually, I really thought about inviting you to the academy to teach those students." of."
"Don't!" Song Qingshu shook his head like a rattle, "Your academy studies are all sage books, which are used to test for fame and fame, and they don't want to learn these physics knowledge for free."
Thinking of the fanatical nerds in the academy, Huang Shinu nodded subconsciously: "Not bad."
"Let's talk~" Song Qingshu changed the subject, looked at the girl in yellow and smiled, "The students in the academy are basically your fanatic fans, if they know about our relationship, I won't be mobilized to attack you .”
"Bah!" The woman in the yellow shirt blushed and couldn't help spitting softly, "What can I have to do with you?"
"The relationship of sharing the same bed, the relationship of kissing..." Seeing that the woman in yellow shirt's face was getting darker and darker, he hurriedly changed the subject, "Ahem, I've already told you the secret of the rain, shouldn't you reciprocate?" Do me a favor."—
