In fact, when the rabbit warrior said that he was in debt and came back, Chen Hui knew that Wangcheng must have developed a business model. Otherwise, how could he say that he was in debt?

You know, the rabbit warrior has been living in ethnic settlements, and there are not many people. When they come to the capital, they will have barter behavior. This is the most primitive way of human business behavior.

For example, if someone needs a sheep and he has only one cow, he will trade his own cow for a sheep, and the gap between cattle and sheep will not be concerned.

Of course, this is just an example. It does not necessarily mean that someone will have a cow to exchange for a sheep.

The example of cattle and sheep is still used to illustrate. If people who own a cow but need a sheep trade their own cattle for sheep, and people who own sheep need food but don't need cattle, the easy exchange will not necessarily succeed.

Even if it is successful, people who want sheep must compromise, first exchange their own cattle for food, and then exchange food for other people's sheep.

This is the inconvenience of the easy mode.

In other words, money is a must for business to develop.

From what the rabbit warrior said, the business model of Wangcheng has been relatively mature. This point has been confirmed by what the rabbit warrior said that many prescriptions in Wangcheng are the same style as Chen Hui's hospital.

Because Chen Hui's hospital was built on the street, completely following the model of the world's street shops he came to build!

Based on these aspects, Chen Hui has already made a judgment in his mind that Wang Cheng is afraid of having money!

With the story of the rabbit warrior, Chen Hui knows more about Wang Cheng.

The first is the size of the king's city. According to the rabbit warrior, the king's city is at least ten times larger than the capital, and the wooden emperors live in the palace of the king's city.

Although the palaces in this world are not as large as those in Chen Huilai's world, they are not comparable to those in the capital. Although the rabbit warrior can't enter the palaces where the wooden emperor lives, according to his description, the palaces are almost as big as the capital!

Secondly, the buildings close to the streets in Wangcheng are the same as Chen Hui's hospital. They have no courtyard. Instead, they directly open the door to the inside. They are not used for living. They are all places that can be changed easily. Each family has its own special items that can be changed easily.

There is no doubt that the rabbit warrior said this point, once again confirmed Chen Hui's previous ideas, Wang Cheng's business model has been very mature, these are the shops along the street!

Moreover, the types of these shops are not the same, which also shows that the business of Wangcheng is extremely developed!

Finally, the rabbit warrior tells about his debt. In fact, he works in a restaurant similar to Chen Huilai's in the world. People only care about his food and accommodation, but don't give him any money. Because he wants to go back to the capital, the boss gives him dry food when he is leaving. These dry food are his debt!

The owner of the restaurant also borrowed the dry food for the rabbit warrior to return to the capital city because he was a member of the Mu nationality. At the same time, the rabbit warrior said that he would return to the King City after a while and hoped that the rabbit warrior would work for him again.

"Yes When the rabbit warrior said this, he seemed to think of something and said, "people in the king's city use this to exchange easily! It's not like we trade things for things! "

With these words, the rabbit warrior took out a metal object in the shape of a fan, which is about the size of a small shell.

Chen Hui took the metal object and observed it carefully. It was not so much a fan as an imitation shell, because there were vertical stripes like shells on it.

Chen Hui knew that in the world he came from, there were shellfish coins in history. This kind of metal product should be the currency at this time.

"Have you ever seen it, sir?" Chen Hui handed the metal products to the old beggar.

After the old beggar took it, he observed it carefully and said, "never!"

Hearing the old beggar's words, Chen Hui understood that when the old beggar left the Royal City, although the emperors of the five nationalities had begun to customize the characters, there was no currency.

"Guess what it is, sir!" Chen Hui said with a smile.

"As the rabbit warrior has said, it's used for barter." The old beggar said with a smile.

Chen Hui shook his head slowly and said, "this is money! In the world I came to, there are also goods for the same purpose, which are used to buy goods, not to exchange goods. Only, the money in the world I came to is made of paper, not metal, and the denomination is divided into size. For example, if an item is worth ten currencies, I give the other party 100 currencies, and the other party needs to give me the items, and get back 90 currencies! "

"Yes, yes, yes!" The rabbit warrior nodded his head and said, "I see people in the king's city, that's what they do. They always use this thing to exchange for food. After receiving it, that family will sometimes give some of the same, but smaller ones to diners!"

"The business of Wangcheng has been extremely developed!" Chen Hui sighed, turned to the rabbit warrior and asked, "how did you get this coin?"

"It's from the family I work for. It's said that it's the rest after I eat and live." The rabbit warrior said, "this can't be used as food. I have to eat on my way back, so I borrowed some dry food from this family."

Chen Hui originally thought that this family was unscrupulous and worked for nothing. Now it seems that this is not the case. They settled their wages.

"If you go to the king's city again, you don't have to take the articles of the capital to exchange easily." Chen Hui said with a smile, "if you remember to go to that family and work for them, if you don't understand, you should ask. This article in your hand should be something like money. At present, I don't know what it is called. But you can buy things in the royal city with it. The first thing to understand when you go to the royal city next time is this one, because this one is not only about your life in the royal city, It's more about the development of our capital. It's a big event! "

"Yes, my Lord!" Rabbit warrior immediately agreed to speak out.

"Sir, do you understand what I'm saying?" At this time, Chen Hui looked at the old beggar and asked.

The old beggar nodded and said, "this thing has changed the mode of easy exchange. It's very convenient for easy exchange."

Chen Hui nodded, frowned and said, "but I still don't know what I call money for this thing."

"What's the matter, my lord?" The old beggar knew that Chen Hui's words were doubts about the world, and immediately asked in a voice.

"Security!" Chen Hui said immediately.
