Datang: Acting as a celestial mystery at the beginning

Li Yi'an originally wanted to ignore them and run away, but they blocked the door, and he was too embarrassed to go too far, so he had to invite everyone in.

As soon as he sat down, Neptune said, "Uncle Li, I'm here to disturb you today. We are very curious. How did Uncle Li know about Archimedes?"

This is what he is most concerned about at the moment. Archimedes is a Westerner, and he has not seen many envoys from the East to the West. Even if there are Easterners, they may not necessarily know Archimedes.

Li Yi'an knows so many things about the West, even buoyancy, which is used to identify the crown, which seems abnormal.

"When Yang Guang was in power, one of your Western envoys came to China. He left some of your Western knowledge back then. I got it by coincidence. Yesterday, I happened to be able to use it again."

Li Yi'an explained casually, and then asked: "I don't know if the envoy has other things to do?"

"Yes, of course there is!"

Before Neptune could respond, Cheng Yaojin said first, "Nepton's envoy is also very interested in our blue and white porcelain."

Speaking of blue and white porcelain, he knew that this time he had to make a lot of money again.

Before that, Cheng Yaojin was still trying to figure out how to let Westerners know the existence of blue and white porcelain, but he did not expect His Majesty to send this assist yesterday.

Neptune let go of his doubts about Archimedes, but after seeing the blue and white porcelain yesterday, he couldn't forget it.

He had a hunch that if the blue and white porcelain was brought back to their west for sale, it would definitely be a huge profit product.

"General Cheng is right. We also want blue and white porcelain. How much can you sell for one piece of blue and white porcelain?"

Neptune put aside his thoughts of making big money for the time being, and he had to get the blue and white porcelain in order to make money.

That hateful Emperor of the Tang Dynasty only rewarded the Great Food Kingdom with blue and white porcelain, but not them. Isn't that just a fake crown? Do you need to be so angry?

"One, 1000 taels of gold!" Li Yi'an didn't talk politely to him, and directly stated his price.

In the Tang Dynasty, when doing business with foreigners, the settlement currency was basically gold.

In the Tang Dynasty, one tael of gold could be exchanged for [-] renminbi at the highest, and the lowest was [-] renminbi. Generally, the most stable exchange price was [-] renminbi for one tael of gold.

Then 1000 taels of gold is converted into [-] guan copper coins.

When Cheng Yaojin heard the price, his mind raced, and he quickly calculated the converted currency amount, which was one thousand coins more than what Changan sold. He was so excited that he was about to jump up.

Li Yi'an's price is considered conservative, because when Neptune and the others come to Datang, they will definitely not just buy one or two to go back. They have to buy in large quantities to make a profit.

But when the amount is large, with the level of gold mining in this era, he is still worried that Westerners will not be able to produce so many gold coins to buy.

When Neptune heard 1000 taels of gold, he was really embarrassed. He has been in Datang for so long, and he has figured out the currency unit of Datang, and understands the concept of 1000 taels of gold.

"Uncle Li, you also know that we are poor in the west and not as rich as Tang Dynasty. Can you make it cheaper?"

Neptune said awkwardly.

"Minister Neptune, blue and white porcelain can be sold for 1000 guan in Tang Dynasty, and 2000 taels of gold is equivalent to [-] guan. If you take it back to the West, you can sell it for [-] taels of gold, right?"

Li Yi'an looked at him and asked directly.

Neptune thought about it seriously, and had no choice but to nod and admit that he still planned to take it back and sell it for 3000 taels of gold and a blue and white porcelain.

"Well, I would venture to ask, how many can the envoy buy at most?"

Li Yian asked again.

"Five!"

Neptune stretched out his fingers.

They dared to carry so much money across the Eurasian continent, Li Yi'an had to admire their courage.

"I can count six blue and white porcelains for the envoys!"

"Really?"

"I don't dare to lie to the envoys. Besides, I have other ways to make the envoys buy more blue and white porcelain."

Li Yian continued to speak.

Hearing that there is still a way, Neptune felt that there was still hope, and quickly asked, "What way?"

"Bargain!"

Li Yi'an said: "The envoy will go back and compile your western theoretical works of Archimedes, Aristotle, Thales, Ptolemy, Celsus, etc. into a book, preferably One book for each person, or one book for each subject, then I will exchange one blue and white porcelain for each book, how about it?"

"Uncle Li, how do you know about them?"

Neptune stood up in surprise, his face full of disbelief.

These are all their Western scientists, philosophers, mathematicians, etc., and some people in the eastern powers thousands of miles away are well aware of their celebrities.

"This is my secret, it's inconvenient to tell the envoy!" Li Yi'an said.

That is the origin of Western civilization. If Li Yi'an says he is not greedy, it is basically impossible. The system can't give him so much, so he can only ask them for it. When the time comes, something will come together, and the world structure of future generations will have to be changed. .

Under the trend of sufficient interests, it is easy for people to take risks and sell everything, especially them Westerners.

"I don't know if the envoy thinks it is feasible?"

Li Yian continued to ask.

"Of course I'm fine, but I'm also in trouble!"

Neptune said: "Those writings are either written on sheepskin, or on sedge tablets, or even wooden boards and stones."

The sedge sheet he was talking about was the papyrus made of sedge by the ancient Egyptians. It was a writing carrier at that time, but it was not real paper. It was just peeled, hammered and smoothed the sedge, similar to the Mayan Flakes made by man from bark.

"Sheepskin and sedge pieces are too expensive, and sedge pieces are not easy to preserve. A book written down is more expensive than a piece of blue and white porcelain."

"Boards and stones are cheap, but they are too bulky to transport over long distances."

Neptune said: "Send it from our capital to Chang'an, and the cost in the middle is also very high."

"That's it?"

Li Yi'an smiled and said, "Ma Zhou, take out my paper!"

After a while, Ma Zhou put more than ten pieces of paper in front of them.

Neptune picked it up and looked at it carefully for a while, then said in surprise: "This is more than a hundred times better than our sedge tablets, but it must be very expensive!"

"This thing is called paper, and it's worthless to us!"

As Li Yi'an spoke, he picked up a piece of paper, crumpled it up and threw it on the ground.

Neptune felt his hands trembling. If these papers were brought back to the West, they might be priceless treasures. They were thrown away like this, and he felt pain in his heart.

"General Cheng, when the envoy returns, give five hundred catties of paper for the envoy to take back."

Li Yi'an said generously: "This should be enough for you to transcribe some of the works. Next time you come, I will send some more. I don't care about the fonts. I just use your Latin. I will find someone to translate later."

Neptune felt more and more that this County Uncle Li in front of him was very strange and mysterious. He even knew their Latin, and even knew more things.

I don't know when it started, but Neptune became a little more afraid of Li Yi'an.
