"Mr. Jiang, I think we should solve this problem as soon as possible, otherwise there will be more and more troubles like this." After the business student sent out the two people he had just argued, he immediately said to Jiang Yu.

"I know, but there is really no solution now. The best way is to restore the use of Tongbao money, but now we don't have too many Tongbao money in our hands. It's impossible to deal with such a large commodity exchange. You are a business student, so you should know the tricks better than me."

"Or how we can do this, we set up an exchange next to the town hall, so that all people who need to exchange goods will go to the exchange to trade. Our exchange sends people to conduct a price evaluation of the items to be traded in units of ingots. After the evaluation, the two parties to the transaction will select the number of transactions based on the reference of this price. Are you optimistic?"

"This idea is very good. Let's do it first. Let's wait until the prince comes back before making plans for the rest."

So, a novel place was created, and there was an exchange next to the city hall.

The exchange's notice reads as follows: "If you encounter any trading conflicts when you want to trade items, welcome to the exchange. Here someone will give a reasonable assessment of the goods of both parties to enable both parties to trade satisfactorily."

The establishment of the exchange has alleviated the contradictions in transactions to a certain extent, but further problems cannot be solved, such as someone who wants to sell things but has not found someone who wants to buy them, or the opposite situation is the case. But in general, the temporary surname has stabilized the problem.

...

"Haha, haha, ha. These are these two things." Others really didn't expect that Zhao Weiji would actually laugh so much.

"Prince, are you sure this is what you are looking for?" Although Wang Dayuan had seen Zhao Weiji's excitement when he first saw corn, the problem was that his performance this time was several times more exaggerated.

Are these two stone-like things that are so precious?

This time, Zhao Weiji was very lucky. Not only did he find potatoes, but he also found sweet potatoes. No wonder he was so crazy about being so happy.

"It's these two things. With them, we won't be hungry again."

Is it so exaggerated? Wang Dayuan doesn't believe it very much, but when he thinks about the corn yield and the effect of filling hunger, Wang Dayuan seems to believe it a little.

"Snow, how much can they sell to us?"

Snow gurgled with the group of Indians living around Lake Titicaca, and the final reply was that they could be sold to Zhao Weiji and others for fifty kilograms of potatoes and sweet potatoes, and asked Zhao Weiji to leave all the gold he had just taken out.

Just now, Zhao Weiji took out about a pound of gold. This was the only precious metal he brought from the Central Plains, to prevent this situation from happening now.

"Give them all, as long as they can take out both potatoes and sweet potatoes immediately."

"Your Majesty, are we at a loss? So much gold can buy dozens of times the grain in the Central Plains?" Wang Dayuan couldn't help feeling a little sad when he saw that Zhao Weiji did not bargain.

"Huanzhang, you don't understand this. With these potatoes and sweet potatoes, will there be less gold? Moreover, such gold is useless in Xinhua City for the time being, so don't worry.

Snow, hurry up and urge them to take out all the agreed things."

Seeing that Zhao Weiji was so cheerful, the Indian chief did not procrastinate, so he immediately sent someone to the south of the tribe to collect potatoes and sweet potatoes.

Just when the chief sent someone to pick up potatoes, Wang Dayuan suddenly found that the dozen or so sailors who came with the team were missing when they came. Wang Dayuan, who felt that something was strange, asked Zhao Weiji in a low voice: "Prince, we seem to have more than a dozen people missing?"

Zhao Weiji whispered without looking back: "It's okay, they all go back first. You can see them when you return to the boat."

When Wang Dayuan heard that Zhao Weiji did not reveal any dissatisfaction, he felt strange, but before he could think too much, the chief sent people to bring 50 kilograms of potatoes and sweet potatoes each.

So the transaction was successfully concluded.

When you get what you want, you will naturally have to go back quickly, because it has been too long since this trip.

...

Two months later, Zhao Weiji finally returned to Xinhua City. It took him five months to find potatoes this time. When he came back, he almost couldn't recognize the city.

At this time, the military camp was gone, and many wooden houses were replaced. Although they were not fighting, they were all pretty good. The streets had been formed, and the city hall was no longer alone. There were many houses around. One of them attracted Zhao Weiji's attention, which was the house with the exchange written at the door.

"What is an exchange?" What a novel thing? Zhao Weiji was full of curiosity. Could it be that the commodity economy here has reached such an exaggerated thing as the futures exchange?

As soon as he entered the city hall and asked, Zhao Weiji realized that he was wrong. It turned out that such a strange thing appeared because of no currency.

"This is my fault. I ignore the consequences that there is no copper coins. I apologize to everyone here." Zhao Weiji was so serious that everyone in the city hall was startled.

"Your Majesty, this is not your fault. We have all neglected it. The key is what to do now. It is definitely impossible to generate a large amount of copper coins in a short period of time. What to do now? Although the exchange has eased the conflict in trading, there are still many things that have not been resolved."

"This is okay. Although copper coins cannot be transformed in a short time, we can mint gold coins. I know where there is a gold mine nearby. As long as the second group of people from Central Plains arrive, they can mine it.

As for the disadvantages of the exchange, we can create a new kind of money to temporarily alleviate the current crisis.”

"What's the money?"

"Paper money."

"Paper money?" Although I have become accustomed to the wonderful ideas that Zhao Weiji often has, paper money is too much. Who would accept that you can buy things with paper?

Zhao Weiji knew that paper money was a bit too much beyond the times. After all, who would believe in such a thing as credit currency in this era? Even if Jiaozi appeared, it would be thirty years before Jiaozi was used. What's more, Jiaozi was supported by a huge money bank, and Jiaozi could indeed exchange for real money.

Now there are no precious metals in Xinhua City, so why don’t you guarantee that you can buy things with your money?

"Is paper money a viable thing?" asked the business student, the founder of the exchange.

"Are you?" Zhao Weiji didn't know this student very much, because after the scale of business expanded, there were too many students. In addition, he kept going overseas and fighting, and the teaching in the academy fell into the first batch of graduates, and he was not very familiar with the later students.

"The prince, whose student's surname is Feng, his name is Feng Yun, and his courtesy name is Huateng. He is a business student at Tsinghua Academy and entered the school in the first year of Chunhua."

"Hmm, hello. You just asked if the banknotes were feasible, right?"

"Yes, prince, students think that banknotes are neither valuable nor safe, so people may not accept this kind of thing as money."

"Your question is very good. You think paper is very cheap and not worth much. It doesn't have a certain value like copper coins. So you don't think you know how to use paper as currency, right?"

Feng Yun nodded.

"What if the banknotes have value? What if the banknotes can be exchanged for gold?"

"How can paper money be exchanged for gold? Who would do such a stupid thing?" Feng Yun felt that Zhao Weiji was a little crazy. He exchanged paper for gold. How many stupid people would do such a thing?

Zhao Weiji knew that it was unrealistic to let Feng Yun understand directly what the gold standard was, so he decided to explain from the beginning how banknotes could be exchanged for gold: "Huateng, you imagine such a scenario, our exchange has countless gold reserves.

Then a farmer brought fifty kilograms of rice, but he did not find the buyer. At this time, we used equivalent gold to buy the fifty kilograms of rice from him. Did he get the same value as fifty kilograms of rice?"

This is the most basic trading attempt, Feng Yun nodded naturally.

"At this time, another woodcutter came. He needed fifty kilograms of rice, but he did not have gold but wanted to exchange it from us with firewood of the same value. Can we exchange it with him at this time?"

"Of course."

"Yes, such an exchange is naturally possible. In this way, the rice we hold becomes firewood. Later, the rice farmer came again. This time he came to sell things, not buy things, and he needed firewood. But at this moment he no longer has rice. Can he want to exchange the gold just now for firewood?"

At this time, Feng Yun was already crazy because all the examples Zhao Weiji gave were some basic business behaviors and the creation of currency.

Of course, you can buy firewood for gold, but Feng Yun still didn't understand what Zhao Weiji was going to say.

"I understand what the prince means. The prince wants to say that if we have a lot of gold, the exchange can become a trading intermediary, and then trade through gold, and gradually gold becomes money. This is the same as copper coins, but you still haven't explained how to turn paper into money."

"Don't be anxious, please listen to my explanation. I think there will be two situations at this time. The first is that gold becomes money, and the second is that all the people in Xinhua City know that there is a lot of gold in the exchange, right?"

Feng Yun thought about it and seemed to be right, because in this way, all the gold on the market flows out of the exchange, and there should naturally be a large amount of gold in the exchange.

"If we start such a business at this time, do you think anyone will respond? This business is savings."

“What is savings?”

"Save means that you store bulky gold in the exchange. The exchange will issue a ticket to prove that you have gold. The ticketing statement states the specific number you have saved. At that time, you just need to take this ticket and come to the exchange again and get the same amount of gold written on the ticket."

"This is pretty good. As long as we can ensure that we can withdraw the gold deposited on the exchange at any time, who would be willing to walk around with the bulky gold?"

"You're right. Will anyone trade bills directly in order to avoid trouble in the long run?"

"It seems to be?"

"In this way, won't paper notes become money?"
