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, but her face was slightly red, and after a long time, she whispered, "You also told me how you did it last night." Pen & Fun & Pavilion www.biquge.info"

Song Qingshu remembered that she even kissed herself last night for the answer, covering the place where she was kissed last night, and couldn't help but smirk.

"Don't laugh!" the woman in the yellow shirt couldn't help but be a little annoyed.

"Okay, okay, don't laugh, don't smile," Song Qingshu saw that the woman in front of him had a tendency to turn into an angry female leopard, and hurriedly said, "Since I have received the payment, I will naturally not deny it." ”

The yellow-shirted woman's face softened slightly, but when she thought of the reward in his mouth, she felt uncomfortable for a while.

Song Qingshu cleared his throat before he 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 the Lei Gong and the Lightning Mother were just myths and legends, but she really didn't know how it rained.

Song Qingshu explained with a smile: "When the sun shines on the earth, water vapor rises from the surface of the ocean and lakes and becomes a part of the air, and when it encounters cold air at high altitude, it condenses into small water droplets. These small droplets are so small that they are not visible to the naked eye. They are small and light, held in the air by updrafts in the air, and come together to form clouds ......"

"Are clouds formed by water vapor?" The woman in the yellow shirt couldn't help but ask, what kind of updrafts and the like could make her feel in the clouds, you must know that people in this world always imagine clouds as a mysterious thing, often associated with various myths and legends, where do you know that clouds are actually ordinary water vapor?

"Of course, I've been to the clouds. Song Qingshu couldn't help but think of the picture of crossing the clouds with Dongfang Duxue in Heimu Cliff again, and a trace of tenderness couldn't help but appear on his face.

The woman in the yellow shirt subconsciously felt that he was bragging, after all, in common sense, only immortals can ride the clouds, but when she thought of the scene where he went to the sky step by step last night, she couldn't help but sigh: "That's right, it's not difficult for you to go up to the clouds with your light skills like yesterday." ”

After imagining the picture 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 water droplets fall?"

"Didn't you just say that those small water droplets are so small that you can't even see them," Song Qingshu explained, "The raindrops you see on weekdays are more than 1 million times the volume of those small water droplets." ”

"A million times?" the woman in the yellow shirt changed her face, and she really couldn't imagine what a million times was like a concept.

Song Qingshu explained to her: "Those small water droplets, also known as cloud droplets, mainly rely on constantly absorbing the water vapor around the cloud body to condense and condense themselves...... Uh, what is Ninghua? You can think of it as strengthening yourself...... If the water and gas energy in the cloud is continuously supplied and replenished, so that the surface of the cloud droplet is often supersaturated, then this condensation process will continue, causing the cloud droplet to continue to grow. ”

"When the droplets grow to a certain extent, as the size and weight of the large droplets increase, they not only catch up with the slower droplets in their descent but also 'swallow' more of them and grow stronger. When the large cloud droplets grow larger and larger, and finally the air can no longer support them, they fall straight from the clouds to the ground, and they will become common rainwater and eventually become raindrops. ”

The woman in the yellow shirt nodded as if she didn't understand, thanks to her full reading of poetry and books, plus she was smart, although there were still many details that she didn't understand, but she still understood the general principle.

"But......" The woman in the yellow shirt suddenly thought of something, and looked at Song Qingshu with burning eyes, "According to what you said, then it can only rain when the cloud droplets are big enough, but how did you control the time of the rain so coincidentally yesterday?"

"Thanks to your help. Song Qingshu said with a smile.

"Me?" the woman in the yellow shirt blushed, "what did I do to you." She thought to herself, she didn't even know how rain works, 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.

"The bag of salt?" the yellow-shirted woman's moist red lips opened widely, "That bag of salt is for rain?" "When she heard the other party's request yesterday, she was confused, but out of trust she still found it for him, and later experienced the shock of his volley to the sky and calling for wind and rain, this little thing was quickly forgotten, who thought that it would be related to rain.

"Otherwise, should I take it for food?" Song Qingshu smiled and continued to explain, "I have already talked about how rainfall is formed just now, but there is another key question that I have not said, that is, how water vapor forms small water droplets in the first place. ”

"How was it formed?" asked the woman in the yellow shirt who was already stunned at this time, and asked completely reflexively.

Song Qingshu replied: "Water vapor must accumulate around dust and other fine particles to form water droplets or ice crystals. These motes are so small that they are not noticeable to the naked eye, but without them, it would not be possible to form a drop of rain, even though there is enough moisture in the air. ”

"So you're going to use salt instead of the dust?" "The yellow-shirted woman Bing Xue was clever and quickly drew inferences.

"That's right," Song Qingshu nodded, "When I reach the clouds, I will use my power to evenly disperse those fine salts, and the water vapor in the clouds will have condensation nuclei, and the speed of rainfall will be greatly shortened......"

Song Qingshu was talking and suddenly found that the woman in the yellow shirt was looking at him blankly, and couldn't help but laugh dumbly: "Do you have flowers on my face?"

The yellow-shirted woman's face turned red, she hurriedly shook her head, and said in a low voice: "I didn't understand what it means to be a pedantic celestial before, but today I finally saw it, you are not only martial arts, but also so erudite......"

"These skills are not worth mentioning," Song Qingshu's expression was solemn, "Actually, my biggest advantage is that I am handsome and chic, and the jade tree is in the wind." ”

The woman in the yellow shirt originally looked at him with admiration, and thought that he would say something that shocked the past and the present, but she didn't expect such an answer, and couldn't help but blush: "You, you, are always so unserious~"

Song Qing spread his hands: "Look at the look of your curiosity just now, if I go down seriously, 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 woman in the yellow shirt opened her mouth, but she still didn't say this sentence after all, and a faint smile appeared on her face: "Actually, I really thought about inviting you to come to the academy to teach those students." ”

"Don't!" Song Qing's head shook like a rattle, "What you learn in your academy are all sage books, which are used to test your fame and rise to the sky, and they don't want to learn these physics knowledge in vain." ”

Thinking of the group of fanatical nerds in the academy, the woman in the yellow shirt subconsciously nodded: "Not bad." ”

"Besides~" Song Qingshu changed his words, looked at the woman in the yellow shirt and said with a smile, "Those students in the academy are basically your fanatical fans, if I knew about the relationship between us, I wouldn't be attacked by a group." ”

"Phew!" the woman in the yellow shirt blushed and couldn't help but take a sip, "What do I have to do with you?" ”

"The relationship between sharing a bed and a pillow, the relationship of kissing......" Seeing that the woman in the yellow shirt's face was getting darker and darker, he hurriedly changed the topic, "Ahem, I have already told you the secret of the rainfall, should you also repay the favor for me." ”
