Bringing System to Great Tang

"There are such magical things? Easy to do?" Li Longji understood.

The thing called a telegram, two people are far apart, can transmit information to each other, almost in the blink of an eye.

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

Li Yi shook his head slightly, researching semiconductors to increase the transmission distance of telegraph signals.

Otherwise, set a point for dozens of kilometers, send the previous one, and receive this point, you can send it directly without translation.

Continuous delivery, finally reaching the destination.

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

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

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

"It takes one year as fast as possible, and two or three years as slow as possible. It is easy to say. It is mainly electronic components, otherwise I will make a simple one for you now, using batteries."

Li Yi has a simple method of making a telegraph without amplifying the signal.

"Higher than the surveillance technology?" Li Longji thought of the set in the palace and the set of surveillance in Zhuangzi.

Li Yi widened his eyes and shook his head vigorously: "The difference is too much. Give me ten years, and I can't make that set of things."

If his technological level reached the level of making that monitoring device, he would have built the atomic bomb long ago.

How many basic industries are involved?

No, there is no need to make atomic bombs. The arsenal will come out to make AK series rifles and remake bullets.

No guns, thousands of people, and one ak can be used to destroy the country.

"Oh~!" Li Longji was rather regretful. He very much hoped that there were more things, and then monitored the whole Chang'an.

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

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

Install surveillance in your home. As long as there is a signal, you can watch it no matter where you are.

"At the moment, the most important thing is to repair the post. Even if there is a telegraph, it is only to transmit messages. The post has a greater effect on the military and people's livelihood."

Li Yi is not too far-sighted. Starting from the basics, the only thing that Datang doesn't need technology is the post.

"It should be completed before autumn, and the newspapers from all over the world will be officially released at the same time."

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

Datang is paving the post station, other places are slower, and the border gate is probably almost the same.

At the same time, the best horses are distributed to the post in Chang'an at the border gate, and use the extreme sprint speed of a horse to deliver the message.

Where the horse cannot walk, the sprint speed of the post **** is tested. What the post **** needs to do is to run from one point to another. When it arrives, there is no trace of strength.

Handing over the letter, this post ran in a relay.

Of course, it is impossible to be alone every time. Wan fell along the way, was bitten by a snake, and asked the tiger to take it away...

"I want to sell the goods to the Japanese country, you can talk about it, Brother Yi." Li Longji knew about currency and was ready to trade with the Japanese country.

Going for the first time, barter.

"Lijiazhuang's tea leaves, embroidery, better kitchen knives, short curly plows, soap, rock sugar, chili noodles, dried carrots."

Li Yi thought for a while and said a few things.

Li Longji doesn't care about anything else, but he has an idea about the plow: "Give them good farm tools?"

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

Li Yi said that the things used by the people of Datang, I believe that the various states and state envoys have collected it long ago. Wouldn't it be said that they were not returned?

Can limit the real thing, but can not eliminate the memory.

Since it cannot be prevented, it is better to be generous.

Today, the capital of the country is in Nara, and it is necessary to bypass Kyushu Island.

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

On Kyushu Island, there is a place dedicated to receiving envoys from other countries, Fukuoka Prefecture, which is also a military location.

However, trading with Kyushu Island does not make much money, and Heijo-kyo is the key place.

By sea to the place Li Yi in Gyeonggi district next door called Osaka at that time, and then walk dozens of miles by land, things can be transported to the capital of Waguni.

Like Jingzhao Mansion in Datang, the people are relatively rich.

"What do you want." Li Longji is nothing to do. Anyway, Li Yi said to prepare these goods.

"Copper, silver, ores are also available. Adjust the price. In addition, the raw silk, cooked silk and silk fabrics of the Japanese country are also required."

Li Yi gives what is needed.

The Japanese smelting technology and embroidery technology are still not enough. According to historical records, this trade has been for decades.

The Japanese government spun silk into cloth and exchanged it for Tang's embroidery.

Copper is also given to Datang, exchanged for the copper coins of Datang, to open Yuantongbao.

The silver is even worse, the technology is not good, and the trade suffers.

Thinking of Waguo's willingness to exchange Yuantongbao, Li Yi added: "Take Zhuangzi's exchange voucher, and the exchange voucher is also very beautiful."

"They won't want it?" Li Longji felt that other countries gave him paper money, but he didn't want it.

"Deliver it free of charge. When the next batch of goods is over, they are allowed to use the voucher to buy things." Li Yi thought of a good way.

The exchange voucher was sent over, and the Japanese people took it to ensure that they were curious, and wrote the amount of money on it.

The key is that banknotes look good and cannot be copied by others.

Then I know next time it can be used to buy Datang items, will you try to trade it yourself?

Even if it is not traded, banknotes will not be thrown away.

Next time you go to Datang, people with banknotes are allowed to buy things, and the credit of the banknotes will be guaranteed.

He even brought some merchants and goods from the Wa country to Datang to show them the role of exchange coupons in Datang.

Regarding this matter, Li Longji took heart. He learned how to bully people with money: "This method is very good."

Li Longji got what he wanted and left happily.

Two days later, Li Longji officially received the Japanese envoy.

The Japanese Kingdom is not a vassal state of Datang, so the credential is equal.

The envoys gave things, Li Longji gave things back, and gave the envoys rewards.

Next, continue to give a banquet, everyone eat and drink, Li Longji asked some things about the country of Japan.

At the end of the banquet, the Japanese envoys returned to the Sifang Pavilion, all very happy.

Datang is still good, and the emperor of Datang is also kind, so proceed to the next step.

The person in charge ~www.wuxiaspot.com~ asks to write to the prime minister and tell me something.

They are anxious and want to determine some technologies as soon as possible.

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

Is it possible to print this? Said to go back to print the books and Buddhist scriptures of the Tang Dynasty.

I don’t know if the hot air balloon can be given. What reason can I find? Said it was flying from Japan to Datang? Fast delivery of messages?

In addition, for medical books, it is best to send someone to teach yourself and others~www.wuxiaspot.com~ is not as good as someone taught.

Let me ask if Li Yi is willing to go to Japan as Datang’s envoy to Japan.

When passing by Henan Province, a new kind of rice was being planted there. It is said that the maturity period is short. Get a boat of seeds back?

With these thoughts in mind, Abe Nakamaro wrote a letter to Song Jing, which was delivered by the officials.

When Song Jing saw the letter, she reluctantly shook her head: "I think too beautifully, Li Yi will not agree."
