Chapter 345

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

Without stopping.

Gu Qian and Gu Yu were admiring each other.

Their Gu family advocates learning, which is not generally valued by learned people.

Both of them thought, it seems that my father and uncle are thinking of soliciting!

If Mr. Huang could go to their family.

Will certainly receive the most grand reception!

Finally, Gu Jing had asked a little panting.

And Huang si still looked the same as before.

Gu Jing suddenly took out a bamboo tube from his arms.

The bamboo tube is not green in color, but withered yellow. It is specially made and extremely strong.

It is inlaid with three crystal lenses.

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

"I wonder if Mr. Huang can help me to have a look at this object? It's my homemade crystal tube that can see the scenery in the distance."

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

"Telescope?"

Gu Jing chewed the word. The more he thought about it, the more he felt real and fit it.

Gu Qian on the other side has shouted:

"Father! That's a nice name! I think it's especially suitable to call it telescope!"

Huang Si shook his telescope.

"Just, you shouldn't use bamboo to make the barrel, but should use metal. Also, it's best to use glass or colorless sapphire for the lens. The diopter of crystal is not suitable. The front and rear should be windproof, and the structure inside should be adjusted in this way..."

With that, Huang Si pinched it with his fingers, and the bamboo tube had split into three pieces in his hand.

Gu Yu was a little anxious and hurriedly said, "how did you break it?"

Gu Jing pressed on his nephew's shoulder and said, "it doesn't hurt. Let him come."

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

He held up the crystal lens and placed it in a triangle.

"You are now a monocular telescope, but if you add a convex lens here and a mirror here..."

Huang Si guided the practice of Gujing telescope.

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

After a while, he looked excited and said, "that's it! That's it! I, I'll try it when I go back!"

Then he quickly bowed down, "thank you for your advice! Mr. Huang really has a talent. I'm reckless!"

Huang Si smiled:

"Don't thank me. It's really amazing that you can invent your own telescope."

That night, it was estimated that Gu Jing had talked to Huang Si. The captain couldn't help coming to Gu Jing.

"Mr. Gu, what do you think of the man named Huang Si?"

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

The sailor doesn't mind. He's the owner of the ship. It's impossible not to mind.

The man named Huang Si's origin is unknown. He doesn't know his purpose when he gets on the boat. It's bad if he does evil.

"Don't worry, captain. If there's something I can bear, and I can pay all the expenses of Mr. Huang on board."

Gu Jing made up his mind and said so.

The captain was surprised: "Mr. Gu, have you ever known this man and would you like to guarantee him?"

"I don't understand..."

Gu Jing said.

"Or rather, probably no one can fully understand him." His eyes looked at the ocean outside the cabin. "However, I don't think a person like him should be detrimental to us... He gives me such a feeling."

The captain followed him and looked out. After a while, he sighed:

"I don't know what this journey will become when this person gets on the boat. I hope it will be a good change..."

"Maybe it'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 and placed in a very special way.

There are four small flat mirrors next to it.

"Take a look from the rear..."

Gu Jing grabbed the captain's tall body and took him to move his head.

After a while, the captain exclaimed in surprise, "you can see clearly this time, and your vision is wider than before!"

"Yes. So I said, maybe it's a good omen."

Gu Jing laughed.

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

The captain hurriedly said, "if he has such talent, it's natural. In fact, when he first got on the ship, I arranged a separate cabin for him to spend the night without letting him sleep with the sailors."

What the captain didn't say was that the cabin was the smallest one on board, and there were some sundries in it. The reason why he didn't let Huang Si sleep with the sailor was just because he didn't trust him.

Gu nodded: "it's so good."

Huang Si sat in his assigned cabin.

I've been here for two days.

This place is really small. Even if you throw everything out, there is only a little place to lie down and sleep.

Of course he won't sleep here!

He only appears on the ship when he needs to appear.

He blinked away when he didn't need to appear.

Now, he is looking at Xiaoke's records about the current technological and cultural level of the Terran.

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

Although the status of slave has not been completely eradicated, most farmers are no longer restricted to personal freedom, but become owner farmers.

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

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

The poor, who do not have their own fields, or have few, can only work for the landlords and plant their fields.

In addition, everyone, whether aristocrats or farmers, has to pay a tax on output.

The proportion of this tax varies from place to place.

The state of Jing is now powerful and coincides with the Lord of the Ming Dynasty. It draws less taxes, which is one tenth.

The state of Chang and the state of song were split from the former state of Lao Chang.

The two countries had to draw heavy taxes for the needs of war, so the state of Chang was one-third and the state of song was one-half.

It's terrible for the government to take half of the harvest saved by the farmers for a year.

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

Today, not only the economy has developed a lot, but also the social system and military technology have improved.

The Terrans learned to make blockhouses, to lay stronger bridges and roads, as well as arrow towers, stone catapults, and so on.

Advanced productivity has brought more surplus value, allowing them to draw a large amount of tax and can afford these consumption.

And these things are sometimes suppressed in turn.

The peasant uprising is now more and more difficult, unless there is chaos.
