Copper coins are certainly not suitable, because with the development of time and technology, copper will gradually become a means of production from a precious metal. If you want to cast a cannon with copper in the future, a cannon will cost several tons at every turn, and no one will cost it, and it will disturb the value of the currency.

Gold and silver are less abundant, but they are less likely to be used in large quantities and can be used as currency. But the problem came again, whether it was gold or silver, the Central Plains was not the main producing area, and the quantity was not enough.

What to do, Hong Tao decided to neutralize it, the gold standard, using gold as the standard currency, and then using copper-iron alloy as a supplementary currency. The auxiliary coin itself has no value, because the melting point of copper and iron is about the same, don't look at it contains 40% copper, but after mixing with iron, tin, and lead, it is difficult to refine it separately with current technology.

Moreover, this alloy has poor machinability, good wear resistance and corrosion resistance, and can neither make precious metals nor make agricultural tools and weapons, and is basically waste.

This thing was not just invented by Hong Tao, but a by-product of the cannon that was cast during the Golden River Empire. At the beginning, Qi Zu led a group of craftsmen to test almost all the metal elements that could be alloyed, and among them was this kind of waste that did not work.

However, it is suitable to use it to mint currency, first of all, the cost is greatly reduced, and secondly, it is not afraid that someone will hoard and melt it in large quantities. You turn it in, it's even less valuable after it's finished, it's a pile of scrap iron, and in the end, you don't have to guard against a large amount of inflow into the enemy country.

If they are willing to exchange gold for this kind of scrap iron, Hong Tao will immediately expand the Weiqiao Town workshop several times, and make every effort to produce scrap iron alloy for them.

Does Hongtao have enough gold to support the economic aggregate of Huangzhou and Ganliang Road? The exact answer is, no!

Hong Tao didn't pay attention to gold at all, although there were a few small gold mines in Huangzhou, and he also seized a few boxes of golden sand, but they were all cast into the emperor's golden body, so they couldn't be turned into any more. If the emperor knew about this, if he didn't say it, he would definitely not be very happy in his heart.

I grabbed some from the city of Ganzhou, but it was a drop in the bucket to no avail, if you rely on this bit of gold to make the gold standard, it is estimated that even Huangzhou will not be satisfied, and when the caravan comes, it will really be a shortage of money.

However, Hong Tao has a way, he did not intend to issue currency by the government at all, but adopted the method of the government issuing standards and the private treasury.

Specifically, the government sets a standard, and whoever has gold at home and wants to spend it as money will take the gold to the Wujin Bank, and the government mint will mint it into a standard gold coin for you, and then it can be put on the market for circulation.

For the time being, the principal in the hands of the government will be borrowed from the people in gold rolls, and interest will be paid, and the principal will be repaid in one or two years. This part of the gold will be used as a reserve, and as many coins will be issued as many coins.

According to government regulations, a certain amount of auxiliary currency can be exchanged for a certain number of gold coins, and no one is allowed to refuse to pay.

To get such a system, coinage is actually the easiest, the black gold bank can make copper-iron alloys at any time, and the casting mold is also handy, the real difficulty is to formulate the rules of the system, and how to get the emperor to agree to implement currency reform in the special zone.

The rules will be formulated slowly by Wang Ba and his younger brothers and sisters, and it will not be too long. Others can't help with policy matters, and Hong Tao must come forward to persuade the emperor in person, and he can't pass letters, that thing is too slow.

As a result, Hong Tao fell ill again shortly after returning to Huangzhou, and it is rumored that he was overworked and needed to recuperate. The residence in Huangzhou Prefecture was crowded with people, so in order to recuperate quietly, he simply moved into the flower paste workshop. If you want to say that Huangzhou is the quietest, it is this courtyard, which is not only quiet but also safe, surrounded by children's groups responsible for guarding.

Lord Shuai Si is sick, still tired and sick, and the people of Huangzhou are very unhappy. This adult doesn't seem to have been idle since he came to fight Huangzhou, first killed people and established power, and then he was busy rectifying the walled fort, building workshops, and then training the army, and took Mawei City in one fell swoop.

After that, he was even busier, not only busy but also playing with his life, taking a few thousand new troops to occupy Liangzhou, and distributing the land to everyone, and he did not lose any benefits.

Finally, when he came back, he had to be busy electing deputies to participate in politics, and handed over part of the power to govern the local area to the people, and at the same time, the mountain road from Tongchuanbao to Lanzhou began to be repaved and widened, and there was no need to recruit the people, and most of the work was done by prisoners.

You said that such a good official, first, does not want rights, second, does not ask for money, third, does not work for the people, fourth, can protect the family and defend the country, and is tired and sick to live, can we not express it?

But if you don't accept things and you can't see anyone when you visit, what should you do? Let's all sum it up, simply, go to the Emperor's Temple to pray for Lord Shuaisi. It is said that the golden body inside is the boss of Lord Shuaiji, and I beg him to use it.

Since the emperor's temple was built, the incense has never been so prosperous, and this time it can finally raise its eyebrows, as if there is a trend of the first temple in Huangzhou.

The originally unknown Emperor Sect has also risen, and the number of believers has gradually increased, for no other reason, just because Lord Shuai Si himself said that he only believes in the Emperor Sect.

Such a lively scene, it is said that Hong Tao must appear as long as he is not sick and can't get up, and take the opportunity to fan again, strengthening the emperor's religion and unifying Huangzhou's religious beliefs is also one of his goals.

However, this time with the exception, the door of the flower paste workshop was still closed, and no one was allowed to enter except for the food delivered by Madame Lian herself every day. Could it be that Hong Tao is really too sick to get out of bed?

That's impossible, if the people of Huangzhou knew what Lord Shuai Si was doing, they would have to demolish the emperor's temple. His people were not in the flower paste workshop at all, and now they had passed Tongchuan Fort, and were following Fu Ji's caravan in the direction of Lanzhou.

It's all just a smoke bomb, he's not sick at all, he's going to return to open the Cover Saint. This request was personally sent to Kaifeng by the wasp before the first day, and then he brought the Zhongzhi back.

After getting the emperor's approval, Hong Tao began to pretend to be sick, apparently recuperating in the flower paste workshop, but in fact, he secretly disguised himself as a member of the camel team and secretly left Huangzhou City with Fu Ji.

Why sneak away? Without it, one is that they don't want the imperial court to know their movements too early, for fear that they will take advantage of their absence to move Huangzhou and Ganliang Road's bad idea.

Second, for their own safety, it doesn't matter in Huangzhou and Ganliang Road, everyone here hopes that Lord Shuai Si can live to be 200 years old, don't change people, everyone is counting on these new policies to live a good life.

But after leaving Huangzhou, I looked around and saw that almost all of them were enemies, and it didn't take too much trouble to ambush myself. He can't rush back to Kaifeng with the new army with great fanfare, so it will be easier to give people the truth, saying that he wants to rebel against the emperor and dare not believe it.

It's better to secretly Chen Cang, except for the emperor and the Imperial City Division, who would have thought that he would suddenly leave the nest in the winter.

"It seems that most of the emperors who are too literary and artistic are unreliable, but fortunately, Your Majesty has no such problem. This King of Liang was a gravedigger of the Northern Dynasty, and it would be a blessing for the Great Song Dynasty if he succeeded to the throne smoothly. ”

Fu Ji's caravan has been wandering around the border of Liao for more than half a year, in addition to selling flower paste, another task is to explore the reality of Liao, and by the way, map data of the border area is mapped.

Hong Tao was sitting in the carriage at this time looking through the information collected by Fu Ji, and the biggest news in Liao during this time was the change of heirs. The current ruler is Yelu Hongji, the name Hong Tao is a little familiar, but it is not seen through the history books, but the martial arts in later generations.

Yelu Hongji has a distinct personality, brave and warlike, and is bent on invading the Liao emperor of the Great Song Dynasty in the south. But under the influence of Xiao Feng, I had to make an oath: In my life, I will not allow a single soldier of the Great Liao Kingdom to violate the borders of the Great Song Dynasty.

In reality, Yelu Hongji did not invade the south, but not for the sake of an oath, but without this idea at all. He is a very serious Sinicization of the Liao emperor, imitating the habits of the Han people to take the word for himself, called Yelu Nilin, and likes poetry, the author of "Qingning Collection".

This is a fight with Emperor Huizong of the Northern Song Dynasty, both of whom have a lot of attainments in literature and art, but how bad it is to govern the country. Obviously they don't have that talent, and it's typical to get into the wrong trade.
