Even if it's exchange behavior, rather than the modern society before Chen Hui, it's also a kind of transaction behavior to trade in the form of currency.

As long as it is a transaction, there must be a certain degree of fairness, the more reasonable.

You can't trade a needle for a sheep.

Of course, there is no difference between the nature of exchange and the nature of transaction. As long as both parties trade voluntarily, it has nothing to do with the value.

Barter is always the most primitive way of trading, and it is bound to develop towards the way of trading with rules and pricing.

Since the capital city is easy to change once every ten days, it must be bound to change behavior, so is Hengcheng.

For example, the village where the film is located can only go to the capital city for easy exchange, but can not go to Hengcheng for easy exchange. Naturally, it can not go to the King City for easy exchange.

It can be seen from this that this is a kind of constraint on easy exchange.

This kind of restriction is actually a kind of restriction and protection on the price of easily exchangeable goods.

For example, if you take an item from the village where Ying is located to the capital city to exchange for grain, you may be able to exchange for a bag of grain. In fact, if you take an item from the village where Ying is located to exchange for grain, you may be able to exchange for two bags of grain if you are in Hengcheng, but if you take it to the King City, you may be able to exchange for more grain.

This is just a kind of analogy, which reflects the ruler's restriction management and protection of the exchange.

This kind of constraint management and protection is inevitable, otherwise, the Mu people will take the things they want to exchange easily, and go to the place where they can exchange the most things easily.

Let's take the previous example to illustrate. In their villages, there is not enough food to eat. Of course, they will take this kind of goods to the King City for exchange, because the King City can get more food.

This situation will lead to the abandonment of the capital and Hengcheng!

Rulers to manage and restrict, not allowed to overstep exchange, not only to ensure the stability of the market, but also let the capital and Hengcheng, to ensure their own interests, so that the city can continue for a long time.

From this point of view, even if there is no money now, it is still in the stage of easy exchange. There should be a vague concept of measuring the value of goods.

Or it can be said that the concept of currency is in its infancy.

"Is it the same with the other four ethnic groups?" Chen Hui asked at this time.

"Jin, Shui and Huo are all like this." The shadow replied.

"What about the Tu nationality?" Chen Hui asked.

"The Tu nationality occupies the central position." The shadow replied: "there is only one city, called the Imperial City, which is extremely huge!"

"How does the imperial city of the four nationalities compare with the imperial city of the Tu nationality?" Chen Hui asked.

Ying shook his head slowly and said, "I haven't been there, just listen to my father. The imperial city of the four nationalities can't be compared with the imperial city of the Tu nationality!"

The Tu nationality occupies the central position with only one city, which is somewhat unexpected to Chen Hui.

However, in that case, the imperial city of Tu nationality must be extremely huge.

When you think about it, it's not surprising.

After all, Tu is the leader of the five ethnic groups.

"The imperial city of Tu nationality will also be changed, right?" At this time, Chen Hui asked, "is it possible to exchange the imperial city of the Tu nationality with the imperial city of the four nationalities?"

Ying nodded and gave Chen Hui a positive answer.

The information that Ying told Chen Hui today is very important. Chen Hui already has a general outline of the five ethnic groups in the world in his mind.

"The four nationality Royal cities are located in the southeast, northwest and four directions of the Tu imperial city?" Chen Hui asked at this time.

"Yes, there are four groups of imperial cities, Gongwei Tu imperial city." Shadow nodded and said.

Chen Hui nodded silently again, pondered for a long time, and then asked: "is the magic of the Mu nationality restraining the magic of the Tu nationality?"

Hearing Chen Hui's question, Ying frowns suspiciously. She doesn't know why Chen Hui asks this question.

"The five ethnic groups are Jinmu shuihuotu. Don't you divide them according to the five elements?" Chen Hui looked at the film and asked in the same puzzled way.

"What are the five elements?" Shadow asked immediately.

When Chen Hui heard the question of Ying, he understood that there was no such thing as the five elements at this time. Therefore, when he asked the question, Ying didn't understand what it meant.

"In my world, gold, wood, water, fire and earth are not five nationalities, but five elements!" Chen Hui explained: "the five elements generate and control each other. The mutual relationship is that wood generates fire, fire generates earth, earth generates gold, metal generates water, and water generates wood. This is a cycle."

The shadow hears of don't understand very much, a face puzzled of look.

Chen Hui can't help but feel a little speechless. If he wants to explain this knowledge point, he must explain what is going on.

However, it was too troublesome to explain. Chen Hui stopped explaining at all and said, "it doesn't matter if you don't understand. I'll tell you that the five elements restrict each other. The relationship between the five elements is like this: Wood controls Earth, earth controls water, water controls fire, fire controls gold, and gold controls wood. This is another cycle!"

Shadow is not trying to understand the details of Xiangsheng Xiangke, nodded and said: "what do you want to say?"

"I mean, the five elements are mutually reinforcing and restraining, and it's a balanced system." Chen Hui explained: "in this Xiangke system, the wood is to conquer the earth, which means that you can understand it as a natural enemy. It means that compared with the Tu nationality, the wood nationality should be dominant!"

After hearing Chen Hui's words, Ying Teng stands up and almost pulls out his sword, which stabs Chen Hui to death.

It is obvious that Chen Hui's remarks are very rebellious in the shadow.

Chen Hui waved his hand and said, "sit down!"

Shadow was silent for a while, then put away the sword and sat down again.

"Now, you tell me, if you fight with the same strength of the Tu warriors, who has the greater advantage?" Chen Hui said: "when I say advantage, you need to make a careful comparison. This advantage refers to the natural advantage I just mentioned. For example, your moves can restrain the opponent, or your wooden wizard's magic, or your Tu wizard's magic, etc.!"

Chen Hui's words were clear and detailed enough. After listening to the film, he fell into deep thinking.

However, Ying didn't give Chen Hui an answer. After a long silence, she stood up and said, "it's getting late. It's time for you to pick herbs."

"All right!" Chen Hui spread his hands, asked nothing, turned and walked in the direction below.

This time, instead of going down with Chen Hui, Ying stood in the field, took a deep look at Chen Hui's back, and then quickly walked up.

Every day, the shadow will go up alone, the destination is the lake, to check the situation of the black Jiao.

However, even when Ying arrived at the lake today, she was a little uneasy. She was disturbed by what Chen Hui had said before.
