The fact that Xu Wenbin was a troll made Qin Hao laugh so hard.

And he is not a simple troll, but has a serious expression and is very serious about correcting other people's wrong views.

In comparison, Qin Maocai was much calmer. He always watched quietly. Occasionally he went to Xu Qing's place to have a look, and then used his finger to drag the screen to write: More, more.

"What the hell is he doing?"

When Xu Wenbin returned home, he was still puzzled by his mobile phone. He finally figured out how Xu Qing made money from those videos. In the blink of an eye, this guy had a whole new job.

Using steel rings as armor?

Just as he was thinking about it, a message popped up on WeChat, which was sent by Xu Qing, recommending handicrafts to him.

"Dad, look at this if you're okay."

"What is this?" Xu Wenbin asked.

"You'll know just by looking at it."

Xu Wenbin tried to find it, frowned when faced with a lot of inventions, and randomly selected a 'homemade inverted hair washing machine' and clicked on it.

A new modern version of torture suddenly appeared before our eyes.

…

"The Greek philosopher Aristotle... In his book "On the Heavens", he was able to put forward two powerful arguments for the belief that the earth is a sphere rather than a flat plate.

First, he realized that lunar eclipses are caused by the earth moving between the sun and the moon. The shadow of the earth on the moon is always round, which is only true if the earth itself is spherical. If the earth is flat

disk, unless a lunar eclipse always occurs when the sun is directly below the center of the disk, the Earth's shadow will be elongated and become an ellipse..."

Jiang He was lying on the sofa reading a book. Reading while lying down was harmful to her eyes. Xu Qing corrected her, but she thought her eyesight was amazing, which was nothing. Sitting all the time made her neck uncomfortable. It was all damage anyway, so weigh it up.

Considering the pros and cons, it is better to lie down.

"why are you laughing?"

Halfway through the reading, she noticed that Xu Qing was wearing a mysterious smile, as if he had done something bad. Jiang He rarely read to him, and now that he had finally read it once, Xu Qing still didn't listen carefully.

"Nothing, you continue."

Xu Qing put away his mobile phone and just pushed the handicraft to Xu Wenbin, so that the old man could see what real idleness meant, lest he come over to ask what he was doing when he was making clothes.

He just did it when he wanted to, there were not so many reasons. He was just satisfying his own interests while adding some added value to this meaningless thing to see if it would attract people to watch.

After he finished it, he put it on and walked around the house, letting Xu Wenbin see the handicrafts he had made when he was full...

"So you are also a philosopher?" Jiang He thought seriously.

"Why do you ask that?" Xu Qing was curious if she knew what a philosopher meant.

"They are all doing meaningless things, such as studying whether the earth is round."

"Why do you think it means nothing whether the earth is round or not?"

"Isn't it?" Jiang He didn't understand the difference between round and flat ones.

Anyway, they won't run to the edge of the sky and fall... What does it matter if it's a triangle?

"Well... obviously not. Only by understanding the nature of the world can we develop better. He discovered that the earth is round, Copernicus discovered that the earth revolves around the sun, and Newton discovered universal gravitation. This is called science."

"Then what's the use of science?"

"Everything we eat, live in, and use is inseparable from science. Did you see the light bulb? There are also computers."

"oh……"

Jiang He was thoughtful.

Xu Qing looked at her suspiciously, wondering if this old woman who had not received nine years of compulsory education had any fantastic ideas.

"Even if you learn this book and science, you still won't be able to go back to Kaiyuan and make a computer to play videos with me."

"Is that so?"

"Don't think about the mess." Xu Qing stood up and rubbed Jiang He's hair, making her hair messy. "Just see if the earth is round. Its purpose is to let you know what kind of world you live in."

The world, understanding the world.”

"Don't mess with my hair."

Jiang He opened his hand dissatisfied and continued reading.

"If you learn mechanics or something... your kung fu should be even better.

It fell from the sky like the Tathagata Palm, using the acceleration of gravity and inertia to increase its power and create a big crater on the ground."

"I will fall to death." Jiang He said.

"All right."

It is unrealistic to expect Jiang He to knock out a time machine or something with his bare hands. Even if she reads a brief history of time, she can only understand the part she can understand, but it is enough to understand what the world she lives in is like, and what the earth and the universe are like.

Having a concept is the first step to becoming smart.

Her understanding of the world has shifted from mysticism to laws, and this kind of laws exists objectively. This new world view allows her to understand the world from another perspective - at least she will no longer regard computers as mythical objects, just some

A great invention in every sense.

If I go back one day, I can also brag to Er Niang and the others, saying that many years later there will be Copernicus who proposed the heliocentric theory, Newton who has many laws to protect himself, Watt who improved the steam engine, and there will be someone who is idle but treats her very well.

Okay Xu Qing.

In the evening, when Xu Qing was feeding the winter melons, Jiang He sat up from the sofa, stretched, put the book aside and prepared to cook.

The meal in the evening was very simple, but quite complicated to make. Jiang He kept busy until nightfall, when it was dark outside the window and the lights came on in the living room, he came out with a large plate of steamed buns and put them on the table.

There are both fennel, egg and cabbage meat fillings, and they are also distinguished in appearance. The plain one has the middle seal twisted into a spiral pattern, while the meaty one is pinched flat by Jiang He.

"I see."

Jiang He suddenly made a sound while eating the meat buns, which made Xu Qing a little confused. What did he understand? Did he understand that she couldn't build a time machine?

"You have no shortage of food and drink, and you have everything you want, so you have a lot of time to do meaningless things, and then you invent these things."

"Have you been thinking about this?" Xu Qing was a little surprised.

"Ah, it just occurred to me suddenly."

"Congratulations on your transformation from a stupid little rice seedling to a smart little rice seedling."

"Am I right?" Jiang He asked.

"Part of it is for this reason. Social development always requires improving productivity first. Insufficient productivity means nothing, so you put potatoes in your bag instead of computers."

"But what's the point?"

"You can think of this, which is meaningful in itself."

Eating and drinking is not just about doing idle things. If Newton was starving to death at that time, he would definitely eat that apple. Who would want to break gravity?

Xu Qing was almost full after eating only five of the fist-sized buns. He still hadn't finished eating the remaining ginger, so he planned to fry them in oil tomorrow and eat them with porridge.

She has long discovered that most food can be left over and fried or stir-fried to make it more delicious, such as steamed buns, rice, fried dumplings and fried pancakes.
