Bai Hao watched the little girl stretch out to herself, and asked suspiciously:

"Yes, what do you want?"

"I, you, I'm going to buy you two packs of sand balls, and I'll give you an extra dime, eight cents." After the little girl finished speaking, she found that the money was gone, and she searched for it for a while, but she didn't find it.

It must have been lost when he followed Bai Hao just now.

Bai Hao didn't think much about it, he had bought everything just now, and he had a long string of hemp rope paper bags in his hand.

Untied the hemp rope and took out two packs, one pack was three cents and five cents when I bought it, Bai Hao didn't plan to ask for money, so he reached out and handed it over.

The little girl was very grateful, and ran away with a sharp bow.

This is the end of the matter.

Bai Hao continued to walk towards the Bund, he wanted to see the river.

didn't take a few steps, the little girl appeared again and pulled the corner of Bai Hao's clothes.

"Can you lend me two cents, I'm going to take the car back."

"Yes, okay."

Bai Hao began to touch his body, the smallest denomination.

This is the big bill.

If you don't eat a big meal for a dollar, you can afford a day's meal.

"Here you go, you don't have to pay it back." Bai Hao handed the money to the little girl, and the little girl shook her head: "You tell me who you are, leave an address for me, and I'll go home and send the money to you." ”

"Forget it, you don't have to pay it back."

"Then I don't want it, I'll go back." The little girl turned around and left.

Two-cent tickets.

Bai Hao knew that the ticket price in Shanghai was five cents, one jiao, one jiao and five cents, two jiao, and two jiao and five cents.

How many stops do you have to sit for two cents, even if you transfer, it will be at least a dozen stops, and walking back, this is the rhythm of walking to a broken leg.

Well, write the address.

Bai Hao clearly wrote on the little girl's homework book, the words Bai Hao of the Ninth Branch of Qinzhou Jingzhao Industrial and Electrical Factory, and then the zip code and so on.

The little girl also wrote her name.

Chu Junlan.

Then he accepted Bai Hao's dollar, turned around happily and ran to the bus stop over there.

But who thinks, one is not careful, and one person pounces on the ground.

One dollar was blown up by the wind and fell into the river, and two bags of sand balls were directly pressed by passing bicycles.

Bai Hao was stunned for a moment, and immediately laughed.

This hapless girl.

Chu Junlan gritted her teeth and got up from the ground, fortunately, the weather is cold now, but the palm of her hand is scratched a little skin, and the sleeves of her clothes are rotten, but the rest is not hurt.

When Chu Junlan looked back, Bai Hao was a little embarrassed, and hurriedly went over to help her up.

"You live there, I'll send you back. It's very unsettling that you look like this. Bai Hao was a little worried about the little girl in front of him, and he felt a little confused.

Chu Junlan pouted, looking at the crushed sand balls on the ground, and wanted to cry uncomfortably.

Ran so far, that's for this.

But it's gone.

Bai Hao squatted on the side of the road and looked at the crushed paper bag, and suddenly asked: "You seem to have studied the delicious food in Shanghai, but you can listen to the accent, you don't seem to be a local in Shanghai." ”

Chu Junlan stood up by herself, didn't let Bai Hao help her, and patted the soil: "My dad was transferred to Mingzhou Port to work, and I temporarily stayed at my aunt's house for a few days on weekends. ”

"Let's go, if there's anything delicious, take me there."

"Well, you have to eat well, or eat enough."

"Eat well, I'll treat you, you lead the way."

Chu Junlan looked Bai Hao up and down for a while, and nodded slightly: "It looks like you don't look like a bad person, okay." The first stop, to eat crab shell yellow, four stops away from here. ”

"Let's go."

Bai Hao planned to eat something and send the little girl home, after all, it was dark.

But soon, Bai Hao discovered that Chu Junlan was a real foodie.

So she can find the inconspicuous scallion pancakes, xiaolongbao, and fried dumplings in the remote alleys. And the taste is extremely authentic.

Talk and get acquainted.

Chu Junlan said to Bai Hao while waiting for the onion noodles: "I came to Shanghai to buy some materials to repair my model, and I signed up for this year's National Youth Invention Competition and Science Symposium, and this year's theme is the sky." ”

"Oh." Bai Hao didn't remember this, because he hadn't participated.

However, Bai Hao had heard this in Lu Ming's elementary school and Yang Liu's high school, and he also knew that this year's theme was the sky, and all forms of registration were accepted.

Chu Junlan took out a picture as if she was showing a treasure: "This is my model." ”

When Bai Hao saw it, he immediately smiled and said, "It's amazing, it's good." ”

"Lie to me, and you won't be able to look down on me." Chu Junlan stared at Bai Hao's eyes when Bai Hao looked at the picture she had drawn, and she trusted her instincts.

Bai Hao waved his hand: "Really, I won't lie to you." As a ...... How old are you. ”

"I'm a freshman in high school."

"yes, yes, as a high school student, that's great."

"Lie to me. I'm not eating, I'm going back. Chu Junlan was a little angry, her family was perfunctory to her, and she didn't have time to watch at all, and now this guy who seemed to be a good person was also perfunctory to herself.

Bai Hao hurriedly said: "Don't, if I tell the truth, you may cry." ”

"Don't be afraid, I want to hear the truth."

Bai Hao took out a pen from his pocket and drew directly on the picture: "You are lying to children, the shape of this wing can fly, but it will affect the power of your model, from the perspective of aerodynamics, the tip of this wing will vibrate in the air, the faster it flies, the greater the vibration, of course the model can't see it." But the motor is so powerful, and a good wing structure will make the model fly higher, faster, and more agile. ”

"Look, I'll do the math for you."

Bai Hao has been studying this recently, because Catherine wants to build airplanes, and they are all top ......, and Jeff Haas is not counted. So a lot of data is to be counted.

The flow function and bit function are out. Chu Junlan was stupid.

She didn't understand.

But she clearly saw that Bai Hao directly changed the thickness, folded angle, and wing angle of the wing. The wings were also designed with a pointed tip to balance the air turbulence.

What is air turbulence.

Chu Junlan didn't understand it at all, but she saw the beautiful drawing with detailed data drawn casually on the paper.

She knew that she had met someone superior.

Bai Hao continued to change: "Double channel, it's too ordinary." Four-channel, I have materials where I live, I'll go back and make a controller for you, four-channel is a good model. ”

"Well, I don't understand these functions."

"I don't understand, it doesn't matter, I just need to understand a few formulas, the model, it's not that complicated. I'll send you some study materials when I get back, it's very simple. ”

"Yes, yes." Chu Junlan nodded violently.

In addition to putting away the drawings, Chu Junlan also asked Bai Hao to write the names of several books, and she was going to go to the bookstore to buy them.

At about ten o'clock in the evening, Bai Hao sent Chu Junlan to the door of her residence, and then called the hotel car to pick him up.

Back at the hotel, Bai Yu asked, "Go eat something for so long." ”

"No, I met a little girl." Bai Hao was not bad at all, he explained the front and back in detail, and finally asked: "What kind of invention and creation competition, what will, get the ranking and get the university entrance examination, do you have extra points?" ”
