What to do? All of a sudden, it rained so heavily, I looked at the weather forecast the other day and it was cloudy. ”

Yan Xiaoke was a little worried.

The place where they are now is a commercial street, and there are some shops selling clothes, but it is already nine o'clock in the evening, and these shops are closed.

It was raining heavily, and both of them were a little wet.

Yan Xiaoke felt a little sad, she had too much fun these days, and she didn't find that the weather forecast had changed when she went out today.

As a result, because I don't have an umbrella with me, I can only take shelter here for the time being.

"Give Uncle Xing a call, I'm afraid this rain won't stop in a short time." Su Mu looked at his phone and spoke.

The weather forecast indicates that the rain will continue until noon tomorrow.

Now it's not very far from the farmstead.

But if you rush back like this, your whole body will definitely become a soup chicken.

It doesn't matter to him, but with Yan Xiaoke's weak body, he must not be able to withstand the baptism of such a heavy rain, so it is better to wait for the family to come out to pick him up.

Yan Xiaoke nodded.

A delivery van was parked in the farm, and Uncle Xing had taken them to a scenic spot two days ago.

"Isn't it a little cold?"

Su Mu looked at Yan Xiaoke and shrank and asked.

The weather in the valley is changeable, and combined with the rain, the chill is felt even in summer.

It's a pity that the two of them are only wearing a simple T-shirt now, and Su Mu can't take off his clothes and drape them on Yan Xiaoke like in the TV series.

"It's okay, let's wait for Uncle Xing to come over first."

Yan Xiaoke leaned into the eaves and approached the window.

It was raining so hard that there were always some raindrops splashing up from the outside, and her bangs were now a little wet, and she ran her hand on the back of her shoulder.

Su Mu leaned forward and blocked in front of her.

Made a phone call from my phone.

Uncle Xing said that he would drive out to pick them up soon.

On the road, there were occasional pedestrians with umbrellas, some walking on their own, some curious glances, and then quickly leaving.

"Hey!"

Su Mu was about to say a few words to ease the atmosphere, but Yan Xiaoke suddenly heard a slight startled sound.

"What's wrong?" Su Mu asked with concern, thinking that something big had happened.

"No, no, I was just scared." Yan Xiaoke hurriedly moved several positions.

The shelter they were now in was the entrance of a clothing store, and in the outermost place, there were two mannequin dummies of that kind of plastic.

At the beginning, Yan Xiaoke didn't notice this, and when he suddenly reacted, he was directly taken aback.

Su Mu pursed his lips and smiled, feeling a little funny.

I took a look inside the store.

Then he couldn't laugh anymore.

Because there is only a little dim light in the store, it does look a little scary against the background of the dark night of the rain outside.

But his footsteps couldn't help but take a step next to Yan Xiaoke.

"It's okay, it's all fake."

Su Mu squeezed out a smile, wanting Yan Xiaoke to relax.

Yan Xiaoke nodded his little head.

But I still think that this kind of model is placed in front of the store, and it is indeed a little infiltrating at night.

"Just don't look over there, Uncle Xing will be here soon."

"Hmm."

Yan Xiaoke's eyes still glanced over there from time to time, swallowing his saliva.

The location in front of the store to hide from the rain is so large, and the models are one on both sides.

Yan Xiaoke gently grabbed the corner of Su Mu's clothes, and his heart was a little more stable.

"Boom !!"

"Shhhh

A sudden white light startled Yan Xiaoke again, and the white light shone on the bodies of these models, like pale real skin.

Yan Xiaoke almost cried out without being frightened, vaguely crying.

Immediately after, there was a rumbling thunder in the sky.

Su Mu: "......"

At this moment, Su Mu also felt a little infiltrated, rain + thunder, plus two dummies here, how could he suddenly have a feeling of the beginning of a horror movie.

"Ahem..."

He felt that he should still say a few words to lighten the mood.

"A total of 3.4 seconds have passed from the white light to the thunder, and the speed of the sound in the air is 340 meters per second, how far do you think we are in the lightning just now?" Su Mu asked.

He felt that dealing with this kind of ghost force was afraid.

The best way to do this is to fight it with physics.

Sure enough, Yan Xiaoke was stunned by Su Mu's question, and he didn't expect Su Mu to change the topic so biased.

"3.4 seconds multiplied by 340, the answer is.... Almost 1000 meters?" Yan Xiaoke replied weakly.

She knew that Su Mu wanted to relieve her attention, so she still calculated it seriously. "34 squared, the answer is 1156 meters."

"However, it's raining now, won't the speed of sound change due to the change of medium?"

Counting like this, Yan Xiaoke's mind suddenly had an extra question.

Su Mu shook his head: "Our current temperature is 12 degrees, and the speed of sound propagation in the air at 15 degrees is 340 meters per second. ”

"The raindrops are small, and they are not continuous, nor are they all on one side, and they can be directly equivalent to being transported through the air."

"There must be a deviation in the specific calculation results, but the deviation should not be very large."

Yan Xiaoke nodded cutely.

I think what Su Mu said is quite reasonable.

Thinking in my head.

Those two models are less terrifying.

"Well, let me ask you another question, do you know why there is often a temperature inversion in the valley at night, but there is a rising air flow to form night rain?"

"This should be a geography problem, which we learned when we didn't have a subject in our first year of high school."

Yan Xiaoke nodded and replied tentatively: "It's the terrain temperature inversion, right?" ”

"The hillside dissipates heat quickly, and the cold air sinks down the hillside to the valley bottom, and the original warmer air at the valley bottom is squeezed up by the cold air, resulting in an inversion of the temperature."

"Hahaha, I actually wanted to study liberal arts when I was a freshman in high school, but then I still studied science."

Yan Xiaoke was very happy to answer Su Mu's question.

The two discussed slowly like this, knowing that when Uncle Xing hurriedly came over, the two were still communicating all the way, "The difference between the temperature of the valley and the basin." Instead, Uncle Xing, who came to pick up people, was stunned.

Yan Fuxing's eyes were more satisfied when he looked at Su Mu.

When he was waiting for the rain, he would only take out his mobile phone to fight the landlord, and Su Mu was able to discuss and study with Xiaoke.

No wonder Su Mu knows so much, and he is still the top student in the college entrance examination.

Moreover, looking at the conversation between Su Mu and Yan Xiaoke, the more he looked at it, the more he felt that the two little guys sitting in the back row were husband and wife.
