After more than 20 questions, Gu Jing asked faster and faster, and Huang Si answered faster and faster.

I don't stop in one breath.

Gu Qian and Gu Yu were full of adoration on their faces.

Their Gu family advocates learning, and they do not attach great importance to everyone who has knowledge.

Both of them thought to themselves, it seems that their father/uncle is thinking about recruitment!

If only Mr. Huang could go to their family.

Sure to receive the most grand reception!

In the end, Gu Jing had already asked a little panting.

And Huang Si is still the same as before, his expression has not changed.

Gu Jing suddenly took out a piece of bamboo from his arms.

This bamboo tube is not a green color, but a withered yellow, specially made and extremely strong.

It is inlaid with three crystal lenses.

Gu Jing put the bamboo tube in his hand and held it, and his tone was already unconsciously full of respect:

"I wonder if Mr. Huang can help me take a look at this object? This is my homemade ...... to be able to see in the distance. Crystal cylinders. ”

Huang Si took it, he held the bamboo tube with three fingers, and said, "Mr. Gu, why don't you name this crystal tube - telescope?" ”

"Telescopes?"

Gu Jing chewed on the word, and the more he thought about it, the more he felt that it was real and fit for this thing.

And Gu Qian on the side had already shouted:

"Father! That's a great name! I also think that the telescope is particularly suitable! ”

Huang Si shook the binoculars.

"It's just that you shouldn't use bamboo for the barrel, you should use metal. Also, it is best to use glass or colorless sapphire for lenses, and the diopter of crystal is not suitable. The front and rear should be added to block the wind, and the structure inside should be adjusted like this......"

As he spoke, Huang Si pinched it with his fingers, and the bamboo tube had split into three petals in his hand.

Gu Yu was a little anxious, and hurriedly said, "Why did it break?" ”

Gu Jing pressed on his nephew's shoulder and said, "It's okay, let him come." ”

After Huang Si separated the bamboo tube, he picked out the crystal lens inside.

He held the crystal lenses up and arranged them in a triangle.

"You're a telescope now, but if you add another convex lens here, add a mirror here......"

Huang Si guided the practice of the Gujing telescope.

Gu Jing watched Huang Si's demonstration, took the lens again, and made a few gestures.

After a while, he said excitedly: "That's it! That's it! Me, I'll try it when I go back! ”

As he spoke, he hurriedly bowed, "Thank you, Mr. Huang, for your advice!" Mr. Huang is really talented, but he is reckless! ”

Huang Si smiled:

"Don't thank me. It's really great that you can invent a telescope yourself. ”

That night, it was estimated that he saw Gu Jing talking to Huang Si, and the captain couldn't help but come over to find Gu Jing.

"Mr. Gu, what do you think of that person named Huang Si?"

The captain is an old man after all, and he can see some clues.

The sailor can not mind, he is the owner of the ship, it is impossible not to mind.

This person named Huang Si is unknown, and he doesn't know what his intentions are when he gets on the boat, so it's not good if he does evil.

"Captain, don't worry, if there is something to do, I can take care of it, and I can do all the expenses of Mr. Huang on the ship."

Gu Jing made up his mind and said.

The captain was taken aback: "Mr. Gu, do you know anything about this person, and you are willing to vouch for him?" ”

"I don't know ......"

Gu Jing said.

"Or rather, probably no one can fully understand him." His gaze looked at the ocean outside the cabin, "However, I don't think that a person like him can do anything against us at all...... He gave me that feeling. ”

The captain's gaze followed him to look out, and after a while he sighed:

"I don't know what this journey will turn out to be when this person is on the boat, but hopefully, it will be a good change......

"Maybe that's a good sign."

Gu Jing patted the captain on the shoulder and pointed to the table beside him.

On the table, three crystal lenses are glued with wooden strips, which are placed in a very special way.

There are also four facet mirrors next to it.

"You look at ...... from behind"

Gu Jing grabbed the captain's tall body and moved his head with him.

After a while, the captain exclaimed in surprise: "This time I saw so clearly! And the view is wider than before! ”

"Yes. So I said, "It's a good omen." ”

Gu Jing laughed.

"Captain, in the future, we must be more polite to Mr. Huang."

The captain hurriedly said: "If he has such a talent, it is natural. In fact, when he first came on board, I arranged for him to spend the night in a separate cabin, and did not let him sleep with the sailors. ”

What the captain didn't say was that the cabin was the smallest on the ship, and there was some miscellaneous stuff in it. And the reason why he didn't let Huang Si sleep with the sailor was just because he didn't worry about him.

Gu Jing nodded: "That's very good." ”

Huang Si sat in the cabin he had been assigned.

Been here for two days.

It's a very small place, and even if you throw everything out, there's only a little room to sleep on.

Of course he's not going to sleep here!

He only shows up on the ship when he needs to show up.

When he didn't need to show up, he teleported away.

Now, he was looking at Xiao Ke's records, about the current level of technology and culture of the human race.

Nowadays, the human race has fully entered the feudal society.

Although the status of slavery was not completely eradicated, most peasants were no longer restricted in their personal freedom and became yeoman farmers.

However, most of the land was still in the hands of the aristocracy.

Farmers who are doing better have their own fields, can be self-sufficient, and can sell some of the produce from their fields.

And the poor, who do not have their own fields, or very little, can only work for the landlords and cultivate their fields.

In addition to this, all people, whether nobles or peasants, had to pay a tax on their production.

The proportion of this tax varies from place to place.

Jing is now a strong country, and it coincides with the Ming Lord, so the tax collection is relatively small, only one-tenth.

Changguo, Song Guo, these two countries, were split from the original old Changguo.

The two countries had to levy heavy taxes for the needs of the war, so the Chang State was one-third, and the Song State was one-half.

It is terrible that the government will take half of the harvest that the peasants have worked hard for a year.

But they can't help it, because the government has soldiers.

Today, not only is the economy much more developed, the social system has progressed, and even military technology has also advanced.

The Terrans learned to build bunkers, to build stronger bridges and roads, as well as turrets, catapults, and so on.

The advanced productive forces bring more surplus value, allowing them to draw large amounts of taxes that can afford these consumptions.

And these things are sometimes suppressed by the peasants in turn.

Peasant uprisings are now becoming more and more difficult, except in troubled times.
