Xueba, I beg you to go and escort him quickly!

Yue Pingting was suddenly disappointed, "I thought it could be bigger!"

Xu Heng, "Theoretically, the limit size of raindrops is about 8 millimeters."

Yue Pingting, "!!!"

"But it's going to be overseas, and there are almost no domestic ones."

"The size of raindrops is closely related to the moisture content of the air and the size of condensation nuclei. Generally speaking, the more intense the rainfall, the larger the raindrops."

"Usually, the size of the raindrops will not exceed 3 millimeters."

Yue Pingting looked up at the light rain in the sky, "Xu Heng, how do you know their size?"

Xu Heng put the hat on the back of Yue Pingting's clothes.

"Silly girl, you can measure the actual size of raindrops by photography, flour, and other methods."

Yue Pingting's mind was full of question marks, "Xu Heng, how do you know all this? Someone really studies raindrops? Impossible, what's the use of studying this thing?"

Xu Heng gave Yue Pingting a white look, Yue Pingting shrank her neck and pouted at Xu Heng.

"People just don't know, so they asked you!"

"Besides, without me, how do you appear to be so knowledgeable?"

Xu Heng, "%￥#@#..."

Hey!

This girl is starting to show logic now.

"Xu Heng, just talk about it! Tell me about it!"

"Please! Please! I know you know a lot, and I want to learn more!"

Xu Heng said angrily, "In the dormitory, I said I know a lot, why don't you learn so obediently?"

Swish!

Yue Pingting blushed, she was about to hit Xu Heng with her fist.

The two were playing and rambling, walking in the light rain.

Suddenly, an umbrella appeared above their heads.

"Take it! I've been working overtime until now, and I'm getting ready to go home. I passed by, and I happened to meet you!"

It's the principal!

The principal even took the initiative to hand over his umbrella to Xu Heng and Yue Pingting!

And even when they didn't have class!

When I was still studying at night, before get out of class was over!

Hit by the headmaster!

The principal's first reaction was not to question or lose his temper, but to hand Xu Heng his umbrella.

"Be careful of catching a cold!"

"I'm leaving! Bye!"

"Oh, by the way, are you guys at school tonight? Or...!"

Xu Heng had black lines on his face, why both of them asked this question!

Xu Heng said helplessly, "At school."

The principal smiled, raised his hand to cover his head, and ran away.

umbrella!

Leave it to Xu Heng.

Xu Heng, "Uh..."

Yue Pingting pulled Xu Heng, "You haven't finished talking, Xu Heng, you haven't told me why you need to measure the size of raindrops?"

Holding an umbrella, Xu Heng and Yue Pingting strolled around the campus.

"When fields are irrigated, raindrops that are too large can damage crops and soil structure, leading to soil compaction."

"Raindrops are too small to be easily contained and cause evaporative losses."

"So, the size of irrigation raindrops is best controlled at about one to three millimeters."

"In addition, raindrops also have a scattering and attenuation effect on electromagnetic waves, which is called rain attenuation."

Yue Pingting suddenly thought, "So this is why when we were young, when we watched TV on a rainy day, there was screen interference?"

Xu Heng, "Yes, the phone signal was not good before, and this is also the reason."

Yue Pingting, "It rains all over the world, it seems that the whole world will be affected!"

Xu Heng smiled, "What you said is not rigorous. Can I say that there is a place that doesn't even have a repair room?"

Yue Pingting was instantly dumbfounded, "Huh???"

Xu Heng, "Because it hasn't rained in that place for 600 years."

Yue Pingting, "!!!"

"Where is that? Where is it?"

Xu Heng, "The City Without Rain."

"However, in our country's rainy cities, it rains for two-thirds of the year."

Yue Pingting listened carefully with her ears pricked up.

But Xu Heng kept silent.

"???"

"Xu Heng, you continue?"

Xu Heng, "We're at the girls' dormitory."

Yue Pingting felt that time passed too fast, and suddenly felt uncomfortable.

"Xu Heng...how about we walk around again! Anyway, the dormitory door will take a long time to close."

Yue Pingting was reluctant to let go.

Forced Xu Heng to walk around again.

She also wanted to hear Xu Heng continue the chat.

but……

Xu Heng has finished speaking.

There's not much more to say.

Yue Pingting, "???"

Xu Heng smiled at him.

Yue Pingting, "%￥#@#￥%..."

"By the way, Xu Heng, you don't need to take the final exam. Will you take the monthly exam?"

"Did the principal come to you and tell you not to let you take the monthly exam?"

"That's not right... You're going to pass the paper this time, how can you take the exam... Hey..."

"Wait a minute! That's not right! Isn't the Nine Schools Joint Examination a mock exam for Senior Three? What does it have to do with our Senior Two?"

"!!!"

Yue Pingting was a little confused.

The joint entrance exam for the Nine Schools is for the third year of senior high school!

Xu Heng is only a sophomore in high school, what does it have to do with him?

"Oh my god! I seem to have discovered something amazing! Are you giving exams to your third-year classmates?"

"You are a sophomore in high school, a classmate in the third year of high school?!"

Yue Pingting stared at Xu Heng with wide eyes.

Xu Heng said indifferently, "Is there any fuss about this?"

Yue Pingting, "!!!"

"Yes! I just got confused! God!"

Xu Heng rubbed Yue Pingting's head and sighed, "I think I probably won't take this monthly exam."

· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·??????????????

"But if I insist, I think I can still participate."

Yue Pingting muttered, "Then you just don't want to participate! These topics shouldn't interest you at all!"

"Hey...my boyfriend, he's so perverted!"

Xu Heng, "???"

"Who would say that about my boyfriend! Yue Pingting, you're going too far!"

"..."

The two wandered outside for a while before returning.

At this time, the students are also out of school.

The rain is also heavy.

Some students were drenched in water, but Xu Heng gracefully held an umbrella and returned to the dormitory.

Put away the umbrella, take this white umbrella, and walk into the dormitory.

With just one glance, some roommates recognized the umbrella.

"This umbrella...the principal also has one!"

"Oh my god! I thought only the principal in our school used white umbrellas, but I didn't expect Xu Heng to have one too!"

Xu Heng smiled, "This is the principal's umbrella."

Everyone, "!!!"

All eyes focused on Xu Heng.

"The headmaster's umbrella?"

"Did the principal give you the umbrella?"

Xu Heng subconsciously nodded.

Because that's the way it is.

Everyone in the dormitory, "!!!"

"Xu Heng, the principal gave you the umbrella, and he left in the rain?!"

"I'll go and go! Xu Heng! I envy you so much!"

"I'm so envious!"

"Jealousy envy hate ah!"

"I'm so envious that it's red, orange, green, blue, purple, and yellow!"

When Xu Heng came back to his senses, the roommates were already dumbfounded.

0 ...... 0

Xu Heng originally wanted to explain, but when he thought that if he said that he was picked up by the principal, they must also say that he has a lot of face, and they are very popular.

"Hey……"

just forget it!

Let's not mention this matter, just wait for the turning point!
