After the issuance of the new currency, although it was slowly implemented in remote towns and mountainous areas, since the promulgation of the tax and conscription system of the "One Whip Law" in Qindong, it quickly circulated in various places, and the speed was very fast, which was also predictable and an inevitable result, because after the promulgation of the "One Whip Law", any people had to pay taxes and forced labor in the new coin, and in order to get the new coin, they had to sell their food crops and other valuable goods to obtain new coins for tax payment.

The problem of internal implementation difficulties caused by the issuance of new coins was solved, but the external problems came again, after Qin Dong ordered the issuance of new coins, and the gold stores opened by the regent's palace in various places announced the ratio of the currency of the Roman Empire to the new coins, the chief envoy of the Eastern Roman Empire to the embassy of Saidika immediately came to the door.

"Great King, Lord Beliscus, the chief envoy of the Eastern Roman Empire's embassy in Saidica, and the military attache, the centurion of Basiliscus, ask to see you!" Batu, the chief of the guard, reported to Qin Dong.

Qin Dong put down the quill pen and got up and said, "Take them to the side hall to meet them!" ”

"Yes, King!" Batu saluted and retreated.

Qin Dong returned to the living room and put on his formal clothes with the help of Martha, and then went to the side hall to meet Beliscus, who was the chief envoy sent to be stationed in Saidica after the Hun Empire and the Eastern Roman Empire sent envoys to each other's capitals, and Basiliscus was his military attache of guards, leading an army of 100 people to protect the embassy.

After Qin Dong arrived, Beliscus and Basiliscus immediately saluted Qin Dong: "The Eastern Roman Empire's envoy to Saidica, Beliscus (military attache Basiliscus), see His Royal Highness the Regent!" ”

Qin Dong walked to the throne and sat down, raised his hand slightly, and said, "You're welcome, do you have anything to do with the two adults coming to see this king?" ”

Beliscus saluted again: "Your Royal Highness the Regent. As the envoy of the Eastern Roman Empire to Saidika, on behalf of His Majesty the Emperor and the Senate, the Emperor and the Senate decided on the ratio of the gold dollar of the new coins to the gold coins of our country, and the ratio of the silver dollars to the silver coins of our country. The ministers expressed a strong protest against the unfair ratio of the square hole copper coin and the copper plate of our country, and the ministers hoped that His Royal Highness the regent could retract the order, and then change the ratio of the coins to 1:1, so that it could be considered fair! ”

After Beliscus finished speaking, Qin Dong really thought that his ears had heard it wrong, "What? You said that the ratio of the exchange rate between China's new currency and your country's coins should be changed to one to one? Did I hear you right? ”

Beliscus panicked when he saw Qin Dong glaring angrily. Cold sweat suddenly oozed from his forehead, but he still stubbornly said, "Yes, Your Highness." You heard it right, that's what the subordinate meant! ”

"Ha, hahaha!" Qin Dong laughed a few times, and anyone could hear his tone. This is the tone of being angry. After Qin Dong finished laughing, he asked: "Then why do adults think that this ratio is unfair, and why do they think that it is fair to change the ratio to one to one?" ”

Seeing that Qin Dong was not angry, Beliscus's face returned to normal, and he suddenly became bold again, straightened his clothes and said: "Your Highness, please ask Your Highness, with the territory that Your Highness can control now and my Eastern Roman Empire, whose territory is bigger?" It should be my country's large territory and large population, right? ”

"That's right. The territory that this king can control now is only half the size of your country's territory! In fact, it is less than half, and Qin Dong said that this proportion is too large. Although the territory of the Eastern Roman Empire is not as large as that of the heyday in the future, it is not comparable to the territory that Qin Dong can control now, and the Eastern Roman Empire now controls all of Greece, Turkey, Cyprus, Syria, Lebanon, Jordan, Israel, Jerusalem, Egypt, and most of Libya.

Beliscus added: "The population of our country has now reached more than six million, and the population on the territory controlled by His Highness is less than one and a half million, for this, Your Highness should agree, right?" ”

Qin Dong nodded, then frowned and said, "Lord Messenger, what exactly do you want to say?" Please say it directly, don't go around in circles, this king doesn't have such good patience! ”

"Yes, yes, the subordinates are going to get to the point!" Seeing that Qin Dong was displeased, Beliscus was a little scared in his heart, and immediately agreed, and then said: "Your Highness, whether it is the region or the number of people, my country is far larger than your country, which shows that my country produces more materials and commodities every year than your country produces, and one copper coin just issued by your country can buy a steamed bun, two copper coins can buy a large scone, and a hundred gold dollars can buy a big house, and in my country, a hundred gold coins can also buy a house of the same size, In the light of the fact that a single ass can buy a loaf of bread made of the same amount of flour, shouldn't the ratio of your country's new currency to our country's money be one to one? ”

The most critical issue between a currency and a currency is the exchange rate, also known as the exchange rate, which is the ratio of one currency to another, which is the price of one currency and another. Due to the different names and values of the currencies of various countries (regions), a currency should stipulate a huàn rate, that is, an exchange rate, for the currencies of other countries (or regions).

So what determines the exchange rate? In the short term, the exchange rate of a country (or region) is determined by the demand and supply of the country's (or region's) currency against foreign currencies. In the long run, the main factors influencing the exchange rate are: relative price levels, tariffs and quotas, preference for domestic goods over foreign goods, and productivity.

The question of the exchange rate is so profound that in the last days of the Roman Empire, even in the 21st century, few people have been able to explain it clearly.

But one thing is for sure, the problem of the exchange rate only exists on paper money, but if it is hard currency, there is no exchange rate problem at all, because hard currency reflects the value of the currency itself, and the value of paper money is artificially given.

Qin Dong knew that this guy had changed his concept after listening to Beliscus, although the value of a gold dollar was a gold dollar, and the value of a Roman Empire gold coin was an Ori, but the value of the two in terms of internal material was different, in terms of the gold content of a gold dollar, its gold content was three times the gold content of a Roman gold coin, almost made of pure gold, its weight was 15 grams, and now the weight of a Roman gold coin was only about 6 grams, and it was also mixed with other metal impurities, and the purity was much lower than the purity of the gold dollar. Therefore, Qin Dongcai set the ratio of huàn to one to three.

Qin Dong glanced at Beliscus and Basiliscus, turned his head to a nearby guard and said, "Go get a gold dollar and a gold coin, and then call the officials of the Mint Department!" ”

"Yes, King!"

Soon, the officials of the Mint came with a gold dollar and a Roman gold coin, "Meet the King!" ”

"Excuse me!" Qin Dong raised his hand and told him to get up, and said: "This is the envoy of the Eastern Roman Empire in Saidika, Beliscus, and the military attache Basiliscus, now this king has a question, as an official of the Mint Department, you must know a lot about the coins we just issued, you tell us, what is the difference between the gold dollars we issue and the gold coins issued by the Eastern Roman Empire!" ”

"Yes, King!" The official saluted, turned to Beliscus and said: "Two lords, the gold content of a gold dollar just issued in our country is very high, and it is almost impossible to purify the impurities in it with the current purification technology, its weight is 15 grams, and as far as I know, the gold content of a gold coin in your country is very underground, a gold coin weighs about 6 grams, but the gold content is only 5 grams. According to the gold content, the value of one gold yuan coin in China is equivalent to the value of three gold coins in your country, this is the difference! ”

Qin Dong showed a smile on his face, looked at Beliscus and said, "Two adults, do you hear me?" That's why my country wants to position the ratio of huàn to one to three, and is there any problem with the two? ”

"But, but," Periscus's face turned red, and he said strongly: "But a copper plate can buy a steamed bun in my country, and a copper coin in your country can only buy a steamed bun in your country, isn't the value of the two the same?" Why is the ratio of huàn to one to one to two? ”

The official of the Mint Department smiled and said: "My lord, I think you have made a mistake, that is, you have set the place of use of these two currencies in your own country, let me give you an example, a copper coin in my country can indeed only buy one steamed bun in my country, but if my country's copper coin is used in your country, then you can buy one or two steamed buns, because its own value is equivalent to one point and two times that of a copper plate in your country, and one hundred gold yuan coins in my country can buy a big house in our country. If these 100 gold dollars are used in your country, you can buy three houses of the same size, I say this, do you understand, my lord? ”

The difference between hard currency and paper money is here, if all countries use paper money, everyone's paper money is made of paper money, it has no value in itself, the reason why it is valuable is the value set by artificially, but hard currency is different, if everyone uses hard currency, then if you want to exchange huàn, you must look at its gold content, and if you don't exchange huàn according to the gold content, there must be a party to suffer.

"This, so that's the case, the subordinates, the subordinates made a mistake, please forgive your Highness, Your Highness is busy with state affairs, and the ministers will not disturb Your Highness, farewell, farewell!" Berrycus's face was extremely embarrassed, and he wanted to slip away after saying a few words.

Qin Dong was not in the mood to embarrass these two guys, but the military attache next to Beliscus Basiliscus attracted Qin Dong's attention. (To be continued......)
