Chapter 954: Trade Varieties and Free Currency

"Is there such a magical thing? Is it easy to make?" Li Longji understood.

It's called a telegraph. Two people can send information to each other even if they are far apart. It takes only a blink of an eye.

"It's not easy to make. Without a triode, the transmission distance is limited. It is necessary to set up a telegraph receiving station on the road in the middle."

Li Yi shook his head slightly. The purpose of studying semiconductors is to increase the transmission distance of telegraph signals.

Otherwise, a point is set up every few dozen kilometers. When the signal is sent from the front, this point can receive it without translation and send it out directly.

Continuous transmission, finally reaching the destination.

This speed is actually quite fast, at least faster than riding a horse.

The disadvantage is that there are too many transfer stations. If one of them has a problem, the information will be inaccurate.

"How long will it take?" Li Longji became anxious again.

"It can be as fast as one year or as slow as two or three years. It's easier said than done. It's mainly electronic components. Otherwise, I'll make you a simple one now, using batteries."

Li Yi has a simple method for making a telegraph machine, which does not require signal amplification.

"Higher than the monitoring technology?" Li Longji thought of the one in the palace and the monitoring system on Zhuangzi.

Li Yi widened his eyes and shook his head vigorously: "It's too far. Give me ten years, and I can't make that thing."

If his technology level has reached the level of making that monitoring equipment, he would have made the atomic bomb long ago.

How many basic industries are involved?

No, there is no need to make atomic bombs. Arsenals come out and make AK series rifles and bullets.

No need for artillery, thousands of people, each with an AK can destroy the country.

"Oh~!" Li Longji was quite regretful. He really hoped that there would be more of that thing, and then monitor the entire Chang'an.

If the distance could be farther, throw it directly to the Protectorate.

He didn't know that what he thought of was used at that time by Li Yi.

Install a monitoring system at home, as long as there is a signal, no matter where you are, you can watch it with your mobile phone.

"For now, it is still important to build a post station. Even if there is a telegraph, it is only to transmit messages. The post station has a greater role in military and people's livelihood."

Li Yi is not ambitious. Starting from the basics, the only thing that Datang does not need technology is the post station.

"It should be completed before autumn, and newspapers will be officially published in various places."

Speaking of this, Li Longji seemed in a good mood.

The Tang Dynasty is building post stations. Other places are slower, but the border is almost done.

At the same time, the best horses are distributed to the post stations from the border to Chang'an, and the messages are delivered at the maximum sprint speed of each horse.

Where horses cannot walk, the sprint speed of the postmen is tested. What the postmen need to do is to run from one point to another, and they have no strength when they arrive at the place.

Hand over the letter, and the post station will take over.

Of course, it is impossible for one person to do it every time. What if he falls on the road, is bitten by a snake, or is taken away by a tiger...

"Brother Yi, tell me about the goods to be sold to Japan." Li Longji knew about currency and was ready to trade with Japan.

The first time he went, he would barter.

"Tea from Lijiazhuangzi, embroidery, a better kitchen knife, a short curved plow, soap, rock sugar, chili powder, and dried carrot cubes."

Li Yi thought about it and said a few things.

Li Longji didn't care about other things, but he had an idea about the plow: "Give them good farm tools?"

"Trade must be led by the Japanese, replenish fresh water in some places, and then go to Heijokyo."

Li Yi explained the reason. I believe that the things used by the people of the Tang Dynasty have been collected by the envoys of various states and countries. If they are not given back, won't they say so?

You can limit the physical objects, but you can't erase the memory.

Since it can't be stopped, it's better to be generous.

Now the capital of Japan is in Nara City, and it needs to bypass Kyushu Island.

There are coal mines on Kyushu Island, and another place with many coal mines is Hokkaido.

There is a place on Kyushu Island specifically for receiving envoys from other countries, Fukuoka Prefecture, which is also a military stronghold.

However, there is no money to be made from trading with Kyushu Island, and Heijokyo is the key place.

Shipping by sea to the place called Osaka by Li Yi in the nearby Gyeonggi District, and then walking dozens of miles by land, the things can be transported to the capital of Japan.

There is a place like Jingzhao Prefecture in the Tang Dynasty, and the people there are relatively rich.

"What do you want?" Li Longji was indifferent. He prepared the goods anyway Li Yi said.

"Copper, silver, ore is also fine, adjust the price, and we also need raw silk, cooked silk and silk fabrics from Japan."

Li Yi gave the things needed.

Japan's smelting technology and embroidery technology are not good enough now. According to historical records, they have been trading like this for decades.

Japan spun silk into cloth and exchanged it for Tang embroidery.

Copper was also given to Tang in exchange for Tang copper coins, Kaiyuan Tongbao.

Silver was even worse. The technology was not good enough and it suffered in trade.

Thinking that Japan was willing to exchange Kaiyuan Tongbao, Li Yi added: "Take the exchange coupons of Zhuangzi. The exchange coupons are also very beautiful."

"They won't want it, right?" Li Longji felt that if other countries gave him paper money, he would not want it.

"Send it for free. When the next batch of goods comes, they will be allowed to use the exchange coupons to buy things." Li Yi thought of a good idea.

When the exchange coupons were sent over, the Japanese were sure to be curious. The amount of money was written on them.

The key is that the paper money looks good and cannot be imitated by others.

When you know that you can use it to buy Tang Dynasty items next time, will you try to trade it yourself?

Even if you don’t trade, the banknotes will not be thrown away.

The next time you go to Tang Dynasty, people with banknotes will be allowed to buy things, and the credit of the banknotes will be guaranteed.

Even some Japanese merchants and goods were brought to the Tang Dynasty to let them see the role of exchange coupons in the Tang Dynasty.

Li Longji was very interested in this matter. He learned how to use currency to bully people: "This method is very good."

Li Longji got what he wanted and left happily.

Two days later, Li Longji formally met with the Japanese envoys.

Japan was not a vassal state of the Tang Dynasty, so the letters of state were equal.

The envoys presented things, Li Longji gave things in return, and gave rewards to the envoys.

Next, the banquet continued. Everyone ate and drank, and Li Longji asked about some things about Japan.

After the banquet, the Japanese envoys returned to the Sifang Pavilion, and they were all very happy.

The Tang Dynasty was still good, and the emperor of the Tang Dynasty was also kind, so let's proceed to the next step.

Find the person in charge, UU read books www.uukaｎsｈu． nｅt Ask to write to the prime minister and say something.

They were anxious and wanted to determine some technology as soon as possible.

They didn't expect gunpowder, which was used for war, and the formula could not be given to their own country.

Printing this should be OK, right? They said they were going back to print books and Buddhist scriptures for the Tang Dynasty.

I wonder if hot air balloons can be given, what excuse can be given? They said they were flying from Japan to the Tang Dynasty? They can deliver messages quickly?

In addition, for medical books, it is better to send someone to teach you and others, because reading books is not as good as being taught by someone.

Let’s ask Li Yi if he is willing to go to Japan as the Tang Dynasty’s envoy to Japan for exchanges.

When passing through Henan Prefecture, a new kind of rice was being planted there, and it was said that it had a short maturity period. Can we get a boatload of seeds back?

With these ideas in mind, Abe no Nakamaro wrote a letter to Song Jing, and an official delivered it.

When Song Jing saw the letter, he shook his head helplessly: "It’s too good to be true, Li Yi will not agree."
