"Uncle Huang, Yang Xiu, this young man, is smart and smart.

But there are some problems with the temper.

You don't have to be annoyed by what he says.

I couldn't help it for a while, and clicked it. ”

After hearing Liu Cheng say that he wanted to summon Yang Xiu over and explain some problems, Guo Jia seemed a little worried, and reminded Liu Cheng in advance here.

When Liu Cheng heard this, he almost didn't laugh out loud.

Yang Xiu, this guy, he knows.

Regarding Yang Xiu's temperament and character, he can even say that he understands it better than Guo Jia.

However, at this time, Guo Jia was able to say these words to himself, which shows that this Yang Xiu is really exactly the same as recorded in history.

It can be seen that during this period of time, he has dealt with Guo Jia, which has made Guo Jia insightful.

Hearing what Guo Jia said, Liu Chengcheng couldn't help but think of You Heng, the No. 1 troll in the Three Kingdoms.

An existence like Yang Xiu is already much better than You Heng.

When encountering the existence of You Heng, that is what really wants people to directly draw their swords and stab him to death on the spot.

But sometimes, if you think about it, you have to admire the courage of people like Youheng.

After all, at this time, there is a huge difference from the time of the later generations.

In later generations, the Internet was developed, and people could not cut people along the network cable.

All of them are wearing vests, and they can't tell who is who.

I don't even know where you live.

Therefore, human nature is infinitely magnified.

Many people can hold a keyboard in their hands and be able to air every second.

With the keyboard in hand, I have it all over the world.

Catch something is a wild squirt.

The main reason for this is that they know that their lives are not in danger.

There will be no price to pay.

This kind of people, once they are put into reality, many of them are often a group of cowards......

But You Heng, the first troll of the three kingdoms, is completely different.

The people he came into contact with were people he could actually see.

And many of them are high-ranking people.

There is no such thing as using your own vest or anything like that.

You Heng sprayed directly like this.

Completely regardless of his own life and death.

Compared with Yang Xiu and You Heng, it can only be said that it is too far behind.

Liu Cheng was also thinking, only one Yang Xiu asked Guo Jia to say this, so if he met You Heng, the number one troll of the Three Kingdoms, what kind of reaction would Guo Jia have?

He didn't know what kind of mood and reaction Guo Jia would have, but he knew that if he could really meet someone like You Heng.

You Heng also doesn't care about it like that, spraying at himself, spraying for the sake of spraying, then according to his temper, he will definitely not give him any preferential treatment.

There will inevitably be retaliation.

It is many times more refreshing to do than Cao Mengde.

After Guo Jia left, it didn't take too long for Yang Xiu to come towards Liu Cheng quickly.

In Yang Xiu's hand, he was holding a notebook, and a lot of things were recorded in the notebook.

It's some of the things he's been thinking about for some time.

With these thoughts, he has already stumped Guo Jia and some others.

At this time, when he went to see Uncle Liu Huang, he was quite excited.

But while I was excited, I also had a lot of thoughts in my heart.

The most important of these is to give Uncle Liu Huang a dismount.

Use these topics that you have come up with to ask Uncle Liu Huang for advice.

Stop Uncle Liu Huang as well.

In this way, you will have face and be able to highlight your cleverness.

Moreover, it is also possible to arouse Uncle Liuhuang's attention to himself through such a method.

Show your talent.

Thinking of this in his heart, Yang Xiu's pace became faster and faster.

I couldn't wait to meet Uncle Liu Huang and quickly implement these things in my heart.

"Boy Yang Xiu, I've seen King Han."

After Yang Xiu saw Liu Cheng, he greeted Liu Cheng very respectfully.

Compared with You Heng, Yang Xiu's emotional intelligence is still much higher.

It's not just spraying for the sake of spraying.

Liu Cheng nodded, smiled and asked him to sit down and talk.

Yang Xiu was not polite, and after saluting Liu Cheng and thanking him, he sat down.

By this time, Liu Cheng had long since left a futon for kneeling and sitting.

All of them were replaced with stools, chairs.

He was really not used to kneeling.

I felt disgusted.

This thing is really painful, and there is nothing wrong with holding on for a short while.

But if it lasts for a long time, it is really uncomfortable.

"I heard that Feng Xiao said that you are very good at learning these natural knowledge.

It is very possible to teach people, and it is also very good to teach.

Haven't you done any of this before?

Sure enough, the hero came out of the boy.

Although he is only a young man, he has already surpassed many people in this matter. ”

Liu Cheng looked at Yang Xiu and said.

Hearing His Royal Highness the King of Han praise himself in person, Yang Xiu couldn't help but smile on his face.

The heart is very useful.

At the same time, the waist bar is straightened up.

Moreover, he didn't think there was anything wrong with Uncle Liu praising himself so much.

I only think what Uncle Liu Huang said is particularly right.

I really deserve such a compliment from Uncle Liu Huang.

However, it did not say so.

"Uncle Huang praised it falsely, but it was just something very simple.

People can understand it at a glance, and it is not worthy of such praise from the emperor's uncle. ”

Okay!

The words he said sounded modest, but in fact, his tone was extremely arrogant.

Liu Cheng smiled when he saw this, this is really Yang Xiu.

At the moment, he was not polite to Yang Xiu, and said straight to the point: "I heard that Feng Xiao said that you have accumulated a lot of questions and want to ask me for advice?"

I have time today, but I can discuss these issues with you. ”

When Yang Xiu heard this, his psychological joy became even stronger.

Immediately, he said: "Uncle Huang, it's true."

This is the way of nature, which I have not known much about before.

At this time, I felt that there was infinite beauty in it.

But there are too many incomprehensible things.

The kid can't figure it out alone, and he doesn't know if he asks others.

I had to come to ask Uncle Pope. ”

Liu Cheng nodded and said, "If you have any questions, just tell me about them."

I'll see if I can help you out.

However, I can't expect too much, and maybe there are some questions that I can't answer and can't explain. ”

Hearing Liu Cheng's words, Yang Xiu couldn't help but smile in his heart.

It's normal that you can't explain it.

If it is explained, how can it be revealed?

He didn't think what Liu Cheng said was modest.

I just think what Liu Cheng said is the truth,

After all, the kind of questions I raised are strange, and I have already asked a lot of people.

Even I can't think of the answers to these questions.

Although Uncle Liu Huang compiled the subject of nature, he is afraid that he will not know much about these.

After all, these questions were raised by Yang Xiu himself, and he couldn't answer them.

Hearing Liu Cheng say this, joy rose in Yang Xiu's heart.

He was not polite, stood up, and after saluting Liu Cheng respectfully, he said: "Uncle Huang, the first question that the kid asked was why this land was round.

The place where you say we are, is a big ball.

But why do we look flat?

How can you prove that it is round? ”

Liu Cheng smiled when he heard this: "This is a big ball, the reason why you can't feel it is because it is too big on the surface."

As big as some of its changes, we can't feel it in the subtleties at all.

It's like a person, from a child to an adult, and then to an old man.

Looking at it day by day, you can't see how people grow up and how they get old.

Only after a period of time can you watch it will you be shocked to realize that before you know it, the child has grown up and the person has become old.

And this earth is a similar truth.

You might say that there are mountains, flatlands, and rivers on the earth, with all kinds of ups and downs.

How could it be a ball?

All I can say is that what you see is microscopic.

If you take a longer view, you'll find that this is not the case.

Its surface, though it is different.

But on the whole, it's a ball.

If you don't understand these things, if you still have doubts, you can go to the prairie, or to the sea, or to the great rivers.

Go to the extremely flat, endless prairie to see galloping horses, to the river and the sea to see sailboats.

At that time, you will realize that when you see the sail in the distance, the first thing you see is not the whole of the ship, but the sail at the top.

Then, from the highest sail, little by little, the whole view of the ship appeared in front of me.

The same is true of watching galloping horses on the endless grassland.

The highest point of the galloping horse is seen first, and then as the galloping horse gets closer to you, you will gradually be able to see it in its entirety.

Doesn't this mean that the earth is round?

If it is not round and curved, then the first time the galloping horse appears in front of our eyes, it should be the whole horse, not just the highest part of it. ”

Liu Cheng said so, so he found a piece of paper and circled it into an arc.

Then with the other hand, I took a pen and started experimenting.

Let Yang Xiu sit there and watch the situation.

And so it turned out.

Yang Xiu looked at the tip of the pen that first appeared in front of his eyes, and then thought about what Uncle Liu Huang said, and gradually felt something different in his heart.

It's like...... It does make a lot of sense.

"Have you figured it out?"

Liu Cheng looked at Yang Xiu.

Although Yang Xiu really wanted to have some doubts about this matter again.

However, after listening to Uncle Liu Huang's detailed narration.

looked at Uncle Liu Huang like this and looked at himself and asked.

If you don't understand, it won't be good to continue to let Uncle Liu Huang tell you.

I am a smart person, how can I let people explain over and over again and hold on to a question?

Doesn't that show that you are too stupid?

nodded immediately: "Uncle Huang, the kid understands." ”

Liu Cheng nodded and said, "Then move on to the next question." ”

"Uncle Huang, then why does this sun, which looks big in the morning, become small at noon?

But the sun in the morning has no temperature

If something is closer to you, it will look bigger.

If the distance is close, it will be hot.

It's the same thing as when we sit there and have a fire.

But why does it get cold when the sun gets closer?

Looks farther away, but it's getting hotter? ”

After Liu Cheng heard what he said, in his mind, he immediately remembered Confucius's journey to the east and saw the texts of the two children's debates.

When he was in elementary school, this question also puzzled him a lot.

I think it's particularly incomprehensible.

I don't understand.

Moreover, even Confucius could not answer this matter at that time.

But at this time, this is not a problem for Liu Cheng.

looked at Yang Xiu staring at himself with burning eyes, looking like he was seriously asking for advice.

Liu Cheng smiled secretly.

He knew that this Yang Xiu wanted to stump himself.

However, it is basically impossible to expect this kind of problem to stump yourself.

He smiled and said, "Sometimes, people's eyes can deceive.

The reason why it is like this is actually to give you an illusion.

The sun looks big in the morning and small at noon, so it feels like it's close to us in the morning and far away from us at noon.

But that's not the case.

One of the most important reasons why this is the case is that there are some things on celestial bodies that cannot be seen as such.

In fact, the real sun, whether it is morning or noon, is the same size.

The main thing that makes you feel different is the refraction of light......"

Liu Cheng stood here and explained to Yang Xiu.

After saying this for a while, Yang Xiu was a little confused.

However, I also understood a lot of things.

After Liu Cheng gave him a detailed explanation for a while, he asked Yang Xiu with a smile.

"What color do you think this sunlight is?"

Yang Xiu blurted out: "White." ”

After saying that, I didn't think it was right.

"No, there's red, and yellow......"

After saying this once, he himself was a little uncertain.

Some people don't understand what color this common sunlight is.

After a while, he looked at Liu Cheng and said, "Then Uncle Huang, what color do you think the sun is?" ”

Liu Cheng smiled: "What you just said is actually true.

It's all sun-colored.

Sunlight is not just one color, but a rainbow of colors. ”

Hearing Liu Cheng say this, Yang Xiuji felt right, but he felt that something was wrong.

He looked at Liu Cheng and tilted his head to think for a while: "Uncle Huang, how can you know that the sun is colorful?" ”

Liu Cheng smiled: "What's so difficult about this?

Come out with me, and I'll have a way to prove it to you. ”

Seeing this, Yang Xiu followed Liu Cheng to the outside.

While walking, I thought about what kind of method Uncle Liu Huang could use to prove to himself that the sunshine was colorful.

He couldn't figure it out even if he wanted to......
