The first rebel of the Tang Dynasty

Let's say that Dai Zhou and Li Shimin came into the library.

I saw a lot of people inside, but it was very quiet.

This shocked Li Shimin a little.

Some things depend on self-awareness, some people are self-aware, and some people are not.

However, as far as scholars are concerned, everyone comes here to study, not to buy vegetables, and they are all reasonable, so their natural quality is higher.

Here, people greet each other with a nod.When you meet someone you know well, nodding is the best choice.

When the two walked into it, it was like entering a maze.

But there were still people nodding with them.

Li Shimin understood very well that he was saluting Dai Zhou.

After all, everyone doesn't know him.

Or that he was too successful in disguise.

Dai Zhou was not rude either, and nodded with a smile on his face.

And so, they walk into it.

Until they reached a place with fewer people.

A water heater is set up here, and many people fetch water to drink here.

And there are cups and other things, which can be said to be very intimate.

The reason why they are in a place with few people is to discuss what to do next.

Li Shimin first said: "Where is this going? Where can I find the answer I want?"

"Master Huang, I'm thinking, let's go to the astronomical area, where there is an introduction about the sky, shall we go and have a look?"

Li Shimin agrees.

"But there are ten floors here, which floor is it on? Do you know?"

Dai Zhou said: "Don't worry about this, just look!"

Following the direction of his fingers, Li Shimin saw a sign in the middle of the patio, which marked the floor plan.

From one to ten.

Each layer is identified.

In this way, if you want to see something, you can just look at it directly through this layer.

"Oh?"

Li Shimin was puzzled!
But go see it anyway.

So the two walked towards the guide board.

The distribution of each floor is written on it,
Tier [-]: Philosophy, Politics

Second floor: military, economic

Three layers: culture, science

Four floors: education, sports

Fifth floor: language, literature

Sixth Floor: Art, History

Seventh floor: geography, astronomy
Eighth floor: biological sciences, health

Nine floors: agricultural science, industrial technology

Tenth floor: transportation, environmental science

Exactly twenty categories.

And the comprehensive ones are in this courtyard.

There are more detailed classifications in each layer.

Unexpectedly, there are so many subcategories in so many categories!
The workload of finishing must not be less!

There are so many talents in the group!

This point is better than the imperial court!
Now the officials of the imperial court only know how to deal with their own affairs.

They each do their own thing.

Li Shimin thought a lot.

When his thoughts came back, he saw the floor they were going to, which was the seventh floor.

This seventh floor is a bit high.

I don't know if there is an elevator. If not, do I have to climb the stairs?
"Let's go up!" Dai Zhou said.

"Is there no elevator here?" Li Shimin asked.

He looked around, but did not see the shadow of the elevator.

Regarding the issue of the elevator, Li Yin said.

Dai Zhou said: "There are too many people, the elevator is not installed! Let's take the stairs."

Tens of thousands of people are here at every turn. If an elevator is installed, it will have to be overloaded every day.

For the elevator, that's not okay, in case it breaks.

It's really not good to have someone trapped in it.

Such harm outweighs the benefits, it is better not to pretend.

Save yourself some trouble!

Li Shimin didn't understand this at all.

Dai Zhou said what he said.

After all, in someone else's territory, it's hard for him to say anything.

"Then, let's go!"

He really wants to know the answer now, so it doesn't matter.

So, the two walked towards the stairs.

The stairs were already full of people.

You even have to line up to climb the stairs.

The two of them lined up all the time and went up the stairs. There were huge floor signs on each floor, so that no one would miss the floor.

Second floor, third floor, fourth floor...

Up to the sixth floor, there are still many people.

Li Shimin muttered in his heart.

Does it mean that people don't read books on the floors below the seventh floor?

So he looked to the side, and there were not many people on the sixth floor.

Then, to the seventh floor.

There are still not many people on the seventh floor.

Watching the people on the stairs still going up.

All the way to the ninth floor, people are going to the ninth floor.

It turned out that everyone went for agricultural science.There is also industrial technology, these two subjects are the most popular among people.

It may be the subject that can get the fastest harvest.

In order to make money, it is normal for people to come here.

Li Shimin didn't think much about it.

Instead, they set their sights on the seventh floor.

He has to study carefully what this day is.

But when he turned his head to look here, he saw a large number of children reading books there.

The oldest of these children was only 13 years old.

There are even smaller ones, estimated to be around six or seven years old.

Each of them had a book in their hands, and they were reading it with relish.

And beside them, there are some adults who are reading books with their children.

This made Li Shimin a little embarrassed.

He touched Dai Zhou lightly.

"Did we go wrong?"

Dai Zhou felt puzzled.

So I went to the floor sign.

There are partitions.

"That's right, it's this floor, and the astronomical zone is on that side!"

Dai Zhou said that he pointed to the place with the most children.

This made Li Shimin embarrassed.

Dare he want to study with these children.

Fortunately, there are also some adults reading books here, otherwise he would die of embarrassment.

"Master Huang, let's go over and see what books are there."

It's all here, there is no possibility of stopping.

So, the two walked towards Tianwen.

When they arrived at Kaiwen District, they were attracted by everything in front of them.

So there are tons of models.

It is the model of the solar system that is placed.

A huge model is placed in a huge disc.

It is the eight planets in the solar system, each with one color, red, blue, yellow, and striped.

Below is a blue background.

This huge model made Li Shimin stare blankly, without moving half a step.

This might be the first time he's seen something like this.

People currently don't know that the planet they live on is called the Earth, and it's one of the eight planets.

Did not know that the earth revolves around the sun.

I don't even know why the moon is bright.

Why are there tides.

Why……

Because they don't have a systematic understanding of astronomy.

In their view, the sky is square and the earth is round.

Even Li Shimin is like this.

He believes that the theory of the interaction between man and nature and the unity of man and nature is in line with his understanding.

His arrival today will be the beginning of changing his perception.
