Cars, trains, taxis, and other means of transportation that he has never been exposed to in his life, Wang Yufei enjoyed them all in one day.

To Guo Jianfeng's surprise, Wang Yufei, who came out of the mountain village for the first time, did not enter the city like Grandma Liu to see everything in the Grand View Garden, which was extremely novel, and seemed to be thinking a lot of the time.

Especially at night, Wang Yufei seems to like to look up at the sky...... , the sky or inaccurate, it is more appropriate to describe it by looking up at the starry sky.

That's right, this little guy especially likes to look at the stars.

"Are the stars so beautiful?" Guo Jianfeng couldn't help but ask.

"You see a lot fewer stars in the city than you do at home. Wang Yufei explained, thought for a while, and then said: "In a book I read in the school library yesterday, it was said that this is caused by light pollution, and the sky glow and glare should be the same. So people in cities tend to go to bed later, so I wondered if we could solve this problem if the whole city used a single-wavelength light source that was easier to filter. ”

"Ahem......" Guo Jiafeng was a little stunned, and he didn't even know how to answer after thinking about it for a long time.

You must know that in the car, he is still popularizing to this child, how beautiful it looks when the neon lights on the riverside of the provincial capital are lit......

As for light pollution?

Guo Jianfeng even felt that this term was the first time he had heard of it.

And the single-wavelength light source? This should be a physics term, right? Did you start learning physics in elementary school?

Last night, after arranging for Wang Yufei to sleep, he talked with Lao Liao in the middle of the night, and the topic was naturally inseparable from the child in front of him.

According to Lao Liao's statement, before yesterday, Wang Yufei really didn't show anything extraordinary, why did his thoughts become so deep after following him? Lao Liao, that guy, is not sincere!

I don't know how to simply change the subject.

"Don't think about this yet, when you get home, don't be restrained. I have already told your Aunt Han about you, and she also welcomes you, by the way, you also have a sister named Guo Xiaoyi, who is two months younger than you, and is now in the third year of junior high school, and you will be a family in the future. Guo Jianfeng said.

"Uncle Guo, can I go to school?" Wang Yufei turned his head and looked at this Uncle Guo's eyes with obvious heat.

"Of course, you can rest assured about this, you and Aunt Han are both in the education system, it is the beginning of the school season, and I will help you find a way tomorrow. Well, when you go back, you can still let Xiaoyi help you with your homework, which is good. Guo Jianfeng patted his chest and said.

......

"Come back, hey, you're Wang Yufei, right? Come in, the room aunt is ready for you, you're tired all the way, are you tired all the way? The meals are ready, hurry up and take a shower when you're full of food and drink, and then get a good night's sleep."

"Thank you, Auntie. Wang Yufei thanked him, changed his shoes like Guo Jianfeng, and was welcomed into the house by the enthusiastic hostess.

The living room is not big, but the decoration is much more elaborate than the house in the village. There was a table of dishes on the table in the restaurant next to it, and it was still steaming.

Before Wang Yufei finished observing the furnishings in the house, a door in front of the living room was suddenly opened, and a girl of the same age as Wang Yufei ran out of her mind: "Dad, I heard that you brought me a brother back?

"Of course! Dad never lied about the military!"

"Okay, don't talk about anything else, eat, eat!"

......

At the dinner table, Guo Xiaoyi kept secretly looking at Wang Yufei......

I'm disappointed!

When she heard her mother say that her father had found her an older brother, the girl was still full of joy.

That's right, in fact, Guo Xiaoyi also wants to have a brother, and in the eyes of girls, having an older brother is a cool thing.

For example, her best friend's brother is handsome, sunny, and can play basketball, go to her best friend's house to play, and see with her own eyes that her best friend can be spoiled in front of her brother, and even help her best friend with her homework......

But Dad brought this guy, obviously 108,000 miles away from her imaginary brother's image?

Dressed in dirty clothes, thin and thin, not sunny at all, and especially able to eat.

She hasn't finished a single bowl yet, and this guy has already eaten three bowls.

What made her even more angry was that her parents were still desperately trying to pick up vegetables for him, and kept asking this guy to eat more, and no one cared about her.

"Ahem, I want to eat chicken thighs too!" Guo Xiaoyi pouted dissatisfiedly.

"If you want to eat it, you can clip it yourself!" Han Qian glanced at her daughter.

"You all served his dishes!" Guo Xiaoyi said aggrievedly.

"Oh, then I'll clip it to you, okay?" Wang Yufei was stunned, and then he reacted and sandwiched a chicken leg and put it in Guo Xiaoyi's bowl.

"Bah, who's going to want you to clip it!Hmph, I'm full, don't eat!" After speaking, Guo Xiaoqian put down her chopsticks and ran back to her room quickly, slamming the door shut.

......

"This kid!" Guo Jianfeng complained: "It's all spoiled by you." ”

"What do you mean I'm spoiled? It's obvious that you follow her in everything!" Han Qian retorted, then looked at Wang Yufei and said, "Feifei, Xiaoyi is a little willful, don't worry about her!"

"Auntie, don't worry, I will take good care of her in the future. Well, it's like a sister. Wang Yufei said seriously.

"Huh?!" these words made Han Qian stunned, this kid ...... How do you act like an adult?

"Do you want me to send her food over?" Wang Yufei pointed to Guo Xiaoyi's small bowl that she hadn't finished eating.

"It's okay, you eat yours, she has a lot of snacks in the house, and she can't be hungry!" Han Qian said bluntly.

"But snacks can only provide excess calories, can't ensure adequate nutrition, I'm almost done, let's send it to her!" Wang Yufei thought about it, quickly pulled out the rice in his bowl, and then picked up Guo Xiaoyi's meal under the complicated eyes of the two adults, and walked towards the girl's room.

......

"Hey, Lao Guo, this kid ......" Han Qian stopped when she wanted to speak.

"Don't worry, it's an obedient child, can Lao Liao still harm me?" Guo Jiafeng replied casually.

"That's not what I mean, why do I think this kid's brain is a little panicked?" Han Qian blinked and whispered.

"Don't talk about it now, wait until the children go to bed at night. You go and watch it first, don't let Xiaoyi play petty, after all, she is not very familiar. ”

......

"Knock knock" When the two adults whispered, Wang Yufei knocked on Guo Xiaoyi's door by himself.

"Who!"

"I, Wang Yufei!"

"What?!"

"Bring you food, snacks are not healthy!"

The door suddenly opened, and the girl's pretended vicious little face stretched out: "I said that I won't eat, I'm going to do my homework!"

"But you still have to eat! Otherwise, you can eat well, and I will help you with your homework." Wang Yufei blinked, and said as a matter of course.

"You?help me with my homework?really?" Guo Xiaoyi glanced at this rustic brother suspiciously, and the door opened slightly......
