The owner of Zhang Guoan pulled up the merchant with a smile and said to them:

"By the way, it's just a business...... You two have a good cooperation, this is a very long-term business! ”

This is true, the peak period of Iwami Silver Mountain mining, the annual production of 38 tons in the heyday, up to more than one million taels, mining time as long as more than 100 years...... This is still smelted using the so-called ash blowing method!

In the 17th century, they produced one-third of the world's silver in Japan!

But from now on, these minerals may not be left in that era. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Zhang Guoan, the owner of the island, also provided them with technical personnel to open mines, such people have been trained a lot in Liuqiu, but they belong to the ordinary technical industry.

He did not ask for the ore to be transported back for fear of jealousy from the Japanese, but because he wanted to cover up the product, he mainly used modern methods to smelt silver......

The method is very simple, he is ready to use dilute nitric acid as the leaching agent to easily leach silver from the ore, and then through the process of precipitation and impurity, complexation and separation, reduction and purification, etc., he can prepare dendritic elemental sponge silver, and he can add ten percent copper to the sponge silver at the same time...... In this way, this silver is probably also the purest silver of this era.

The silver obtained by this method is of high purity and in large quantities...... The key is that the requirements for mechanical equipment are very low.

In fact, in the 17th and 18th centuries, it was the Spanish colonizers who used this leaching method to refine silver in the Mexican silver mines, which greatly increased the world's silver production and officially made silver an ordinary currency.

As mentioned earlier, during the Great Song Dynasty, silver and gold were just bank checks or credit cards, and basically could not be used as currency for direct consumption.

Therefore, it is mainly copper coins as hard currency.

This is easy to do, they also have the longitude and latitude coordinates of the Liuqiu copper ore in their hands, Wang Defa is ready to lead a team to the north of Liuqiu to find it personally, and then directly use the concentrated sulfuric acid leaching method to smelt, although the cost is large, but its production is more and the quality is good...... The concept of cost in this time and space is different from the concept of time and space in that side.

They began to develop further, but Zhang Guoan, the owner of the island, was still not ready to let go of an old dog of the Great Song Dynasty.

Zhang Guoan, the owner of the island, asked Yang Youxing to publish "The Theory of the Six Kingdoms" and other articles in the "Liuqiu Weekly", emphasizing that "the destruction of the Six Kingdoms is the disadvantage of bribing Qin" by commemorating Su Xun, and at the same time secretly accusing the Great Song Dynasty of bribing the Tatar diplomatic means......

After seeing it, Pingzhang Jia seemed to say that the old dog smiled, ignored it, and then sent a lot of baggage to the Shandong Peninsula!

Captain Bowie reported that there was no need to supply anything other than weapons and equipment......

Zhang Guoan, the owner of the island, asked Yang Youxing to publish an article in the "Liuqiu Weekly" to praise Zhao Kuangyin for how brave he was back then, and criticized people such as Li Yu of the Later Tang Dynasty for not wanting to make progress and being content with the status quo until the kingdom collapsed...... used high-level black techniques to criticize the current situation of the Great Song Dynasty.

After seeing this, Pingzhang Jia seemed to say that the old dog grinched, and then ignored them, he directly discussed with Zhao Yu, the official of the Great Song Dynasty, and dispatched 10,000 excellent soldiers, let them take off their military uniforms, and go to the Shandong Peninsula one after another in the clothes of ordinary people, so that they can change into the clothes of the Liuqiu Guards and obey their commands.

At that time, Zhao Yu, an official of the Great Song Dynasty, immediately sent Fa Ke to control him, and asked him to also take half of the Imperial Arquebus Army and go alone in a team.

Pingzhang Jia Rudao found the law and said, "Do you know why the official family sent you to the battlefield at this time? ”

The Fa Ke system has almost been suffocated in the past few years, and he was left by the official family and couldn't go anywhere, so he could only practice all day long, and seeing others receiving merit and rewards, he could only stand still...... The size of the Imperial Front Army is there, and it is impossible to expand the army further.

Fa Ketong said: "The official family must let me fight against the Tatars and fight the bravery of the Great Song Dynasty!" ”

Pingzhang Jia said: "This imperial army was built by the official family, and it was cultivated by the official family, he can't go to the battlefield, so naturally he can only let you go to the ...... You are fighting for him, so you can only win and not lose, and in addition, you often have to send secret letters to the officials, and you can only report good news, not sorrows......"

Pingzhang Jia said the last sentence meaningfully: "You are not you anymore...... You are the eyes of the officials. ”

The law can control the heart and convince orally, and do it one by one.

In fact, their Imperial Front Army had already sent a team to rotate training, and it was effective, but this time it was going to be a large-scale operation.

Pingzhang Jia seems to be the old dog who can say that he can fight the general, Chinese the highest, or the best among the civil servants to lead the team to fight...... At this level, he can also understand the truth of cold lips and teeth, so the supply of convection guards is quite generous.

Well, Zhang Guoan, the owner of the island, can only ask Yang Youxing to stop blacking this old dog at a high level, and instead mock the phenomenon of the next voice in the country to the Great Song Dynasty.

For this reason, Zhang Guoan, the owner of the island, casually took out a cartoon he saw in that world.

The cartoon depicts people who have no freedom of speech, only praise.

Zhang Guoan, the owner of the island, also said meaningfully to Yang Youxing: "If criticism is not free, then what is the point of praise......

This cartoon was supposed to be heavy, but it made the citizens of the Great Song Dynasty laugh when they saw it, and even learned this method of expression immediately.

For a while, comics began to take off.

Zhang Guoan, the owner of the island, was quite regretful...... Quiet but optimistic, he said, "What are you worried about? ”

"Quiet, I'm worried that the old dog's actions to suppress free speech will undermine economic freedom, and the two are often related."

"Don't worry about Guoan, they can at least let the private sector publish a newspaper, at least your "Liuqiu Weekly" can be sold by them casually......

Hehe, Zhang Guoan's owner scratched his scalp, and it was different to look at the problem from a different angle.

The Practitioner ...... The free economy of the Great Song Dynasty is too important to him, without their market, he would not be able to die here, but it will develop at a turtle speed.

The owner of Zhang Guoan had no choice but to calm down, just as if he had been tricked by an ancient, and he should pay attention to it next time.

When the mind was at peace, the days passed quickly, and in the blink of an eye it was the spring of 1271.

This spring is the spring of Zhang Guoan's owner, and after being busy with spring ploughing, he is ready to officially issue his own currency.

Liuqiu Qianxing, now it is just a three-story building, when the day of the listing, Zhang Guoan's two sons led their son Zhang Zhansheng to the platform by himself, and he came at the same time as Mayor Yao Mai.

The reason why Mayor Yao Mai took the initiative to come was that he was informed by the owner of Zhang Guoan, saying that in the future, Fenglu of their city government would have to receive it directly from Liuqiu Bank.

There is only one at the moment, but three more will be built in the future...... For the time being, the owner of Zhang Guoan did not dare to directly announce that the Liuqiu area could only use the Liuqiu currency, so he could only grit his teeth and allow the two currencies to be used at the same time, and he accepted the reality that the banknotes of the Great Song Dynasty could be exchanged for Liuqiu currency, which was the initial pain of the policy.

However, he directly ordered the customs to collect taxes only on the flow of coins, and all important products, only for the flow of coins.

In this beautiful spring, he still has to take his time.

Gu Jianshan was appointed as the president of the Liuqiu Money Bank, and he behaved decently at the listing ceremony, and it seems that several years of customs work have made him stable.

In the territory of the Great Song Dynasty, the Liuqiu Money Bank that they rented or bought was also officially listed, accepting the deposit and exchange of Liuqiu and the local area, including loans and other businesses. (To be continued.) )
