Li Yuanjing's set of theories is still a little high-end for everyone, and even Li Yuanjing himself is difficult to figure out some of the secrets.

Anyway, he only knew that making gold and silver an international currency would be of great benefit to Datang.

Moreover, at present, Datang has mastered the gold and silver mines of the peninsula, Dongzhou and Hokkaido, and a large amount of gold and silver will be put into storage every month, but the amount put out is far less than the amount put into storage.

According to the current situation, the amount of gold and silver stored in the treasury will increase, and if you want to spend it, you will have to exchange it with enough copper coins.

This idea was also put forward by Li Yuanjing in order to avoid rapid inflation.

"Why don't I understand it anymore?" Li Shimin thought hard, but he couldn't think of how to explain it?

"In fact, it is very simple, the current gold, silver and copper exchange rate is actually to stabilize the current monetary system, so that the people continue to guarantee confidence in the existing system, so as to accept it willingly, rather than to run, this system must continue to be maintained, the early imperial court must control this amount, and the amount of gold and silver put into the market must not be much.

But the gold and silver in the hands of the imperial court cannot be kept all the time, and it always has to be spent, since the local people can't spend so lavistly, then they can be spent by foreign countries according to the value of the locals.

Next, the development of various places needs to use a lot of labor, all from the Tang Dynasty is a little unrealistic, so the next these labor, will be exported from Boli, Jili, Dandan and other countries nearby, in addition to the peninsula and the export of the country, the output of labor in these places will account for more than seventy percent of the entire required labor, and the rest is the people of the Tang Dynasty.

In addition to taking care of food and housing, these people in the Tang Dynasty pay a certain amount of wages every month to give them the opportunity to make money, these local ministers have been to see it, they are so poor that even the royal guards can hardly guarantee that each person has a coarse cloth clothes, and when the time comes, just the output of cloth will be enough to earn the money back.

In other words, there is a lack of everything, Datang can make money in the past by engaging in some commodities and goods at will, and Pi Bu is not worth a hundred dollars in Datang now, but where it is transported, Pi Bu can be sold for at least one or two silver, which is still the price given by Xinshan. Li Yuanjing explained with a smile.

"But Datang's copper coins still haven't increased, even if you can earn these money back, what's the use?" Dai Xuan asked with a frown, the concept of exchange rate delivery had been deeply buried in his mind.

"Copper coins are only used as a base currency for the grassroots people to use, and there is only one thing for the imperial court to do, that is, to always let the people maintain confidence in this monetary system, as long as the confidence is not reduced, these systems will not be of much significance in a few years.

When it comes to more than ten transactions, the first choice of the people is gold and silver, rather than finding a way to exchange it for copper coins, and at that time it is the real success, and setting a fixed exchange rate is just to let the people have confidence in the court and maintain economic stability. Li Yuanjing smiled.

It's just a simple gold, silver and copper currency system, which hasn't moved out the credit currency yet, so don't scare you guys to pee your pants?

Zimbabwe, one of the richest countries in the world, used to wipe the toilet with money, because the price of a piece of paper may not be able to buy a pile of money.

"In this way, there is no need to worry about the development of Island No. 1!" Li Shimin nodded, although he still didn't understand it a little, but in the next overseas development, he could rest assured that he could boldly use millions of labor.

Li Shimin frowned and thought about it, he had been thinking about this matter for a long time, but the stakes were so high that it was difficult to make a decision immediately.

And there are all kinds of issues involved, which is very complicated.

But now, reform is imperative, because the existing system is basically on the verge of collapse, and the requirements of the government soldiers are too high, and the people are gradually unable to bear this burden.

"What do you think of the idea of reforming the army?" After a long time, Li Shimin finally spoke.

"Your Majesty, money is the key......"

"Yes, according to the Tang Dynasty's territory, at least one million troops are needed to maintain the status quo, even if each person needs a consistent military salary every year, but the annual food and clothing is not a small amount, plus the camp or something, it will cost tens of millions of dollars a year......

The current strength of the Tang Dynasty is seriously insufficient, and the government soldiers can only barely ensure the stability of various places, and once a war breaks out, other soldiers must be temporarily recruited.

The other is the border army, which should be rotated every three years according to the regulations, but the reality can't do it at all, and there will be no one in the rotation, so now it is basically good to be able to rotate once every four years.

In a few decades, the situation in Datang will be even worse, and even those who go to the border may not be able to come back for ten years, and there will be no one to replace them at all.

"Your Majesty, the restructuring is not a trivial matter, it is not only the government soldiers who have been changed, but also the border army and something that must be counted, in addition, it also involves the labor of the people...... Fang Xuanling cautiously reminded.

"Your Majesty, the Haizhou Army's salary is too high......" Li Daozong suddenly stood up and said.

What the imperial court lacks is money, but there is a precedent of the Haizhou army, more than 100 yuan per person every month makes the court feel numb when they look at it, and they also take care of food and housing, and there is meat to eat every once in a while, these are all expenses.

The reason why the Haizhou Army has been able to support it until now is because of the sponsorship given by those family gate valves, and the other is that Li Yuanjing's three mines are supporting, once the family gate valve withdraws from the sponsorship, Li Yuanjing basically doesn't think about the output of the three mines.

"How much does the Haizhou Army spend in a year?" Li Shimin was puzzled, he knew that the Haizhou army was highly paid, but he didn't care about the total expenditure, he only knew that it was not low.

"In the first year, we had to build a military camp, and it was less than half a year, and the expenditure was almost more than 400,000 guan, and in the second year, I went to Silla, and there was a war subsidy, and the expenditure was nearly one million, and this year it was even more, more than 10,000 people went to sea with the ship, and the subsidies plus rewards were added to the average of more than nine guan per person, and then counting the others, this year's expenditure has exceeded one million guan...... "Li Daozong said, he is more familiar with the situation of the Haizhou army, although he has reported!

“……”

Li Yuanjing suddenly felt that the air around him seemed to be much colder, and the dissatisfied eyes of the ministers came one after another.

The annual expenditure of 50,000 people is one million, so if the imperial court supports one million people, won't the annual expenditure be 20 million? That's the basic overhead!

You must know that Datang's annual income is not 20 million yuan, unless it is unlimited to invest in the mined gold and silver.

Li Yuanjing also knew that he had committed public anger, although he didn't want to, but the Haizhou army was in front, which did have a huge impact and resistance to the military reform of the Tang Dynasty.

After thinking about it, he said tentatively: "Why don't you change the Haizhou Army to the Tang Navy?" All the other troops were changed to the Tang Army? It means that the troops at sea and the troops on land, the navy has opened up so many new territories for Datang, and it has to suffer so many unknown dangers, so it is nothing to give a high point of military salaries, right? ”
