In fact, in the hearts of the old beggars, Chen Hui was born as emperor Xing and the firm co leader of the five ethnic groups. In their view, Chen Hui should have something special. He should feel that the things coagulated by the five ethnic groups' different auras contain the auras of the five ethnic groups. He should not feel that.

In other words, although the old beggars said so, there was a little disappointment in their heart.

No, to be exact, they feel sorry for Chen Hui.

It is for this reason that the old beggar would say such things to Chen Hui in a joking way. Otherwise, the old beggar's character is not such a joker.

How can Chen Hui not understand people's thoughts?

"Don't say much, sir. I've already said that there are gains and losses!" At this time, Chen Hui said to the old beggar, "it's not a pity that you can't feel the aura of the five ethnic groups. It's not a pity that it contains aura."

After a pause, Chen Hui said, "Sir, when is the moon in the sky the most round?"

"Fifteen, sixteen!" The old beggar replied immediately.

"Before and after these two days?" Chen Hui asked with a smile.

"Before these two days, day by day round, after these two days, day by day short!" The old beggar replied.

"Everything in the world can be compared with the full moon!" Chen Hui light said: "absolutely can't pursue consummation, once consummation, will usher in must be lack, sir can take the full moon, and I said the gain and loss want to compare!"

Hearing Chen Hui's words, not only the old beggar, but all the people present were lost in thought.

The old beggar and Jie have the highest savvy. They soon come back to their senses. Chen Hui uses the full moon to explain the gain and loss. If there is gain, there will be loss!

At this time, they feel sorry for Chen Hui. Chen Hui can't feel the real things coagulated by the auras of the five nationalities. The different auras contained in them are actually pursuing the full moon!

The so-called one Li Tong, one hundred Li Tong!

After understanding this, both the old beggar and Jie found out that the truth about the full moon is far more than the gain and loss. Chen Hui told them that the truth about the full moon really has the meaning of simplicity.

"Thank you for waking me up!" The old beggar and Jie said it almost at the same time.

Chen Hui waved his hand and said, "Sir, please continue to solve my doubts!"

Chen Hui's words obviously ask the old beggar to continue to explain why this kind of metal currency can't be forged.

Therefore, what was explained before was only the changed currency of the Jin nationality, which can tell the true from the false at a glance.

The old beggar nodded and said, "my Lord, before that, I have something else to tell you."

"Go ahead, please Chen Hui nodded and said.

"In the case of the wood clan, it can be turned into a kind of wood. This city Lord's mansion is built with a lot of wood. These wood need to be made before they can be used!" The old beggar pointed to the beams, pillars, wooden doors and windows of the meeting hall and said, "do you know why we need to make them instead of using aura coagulation?"

There is no doubt that the meaning of the old beggar obviously means that the wizard can directly condense into beams, columns, doors, windows and other shapes with the aura of the wood clan. It does not need to collect wood to make them. If the aura is used to condense, it will be much easier than making them.

However, the actual situation is that all the wooden components used in building houses are made of wood.

"It needs a wizard to have profound cultivation to condense the spirit into the real object." Chen Hui said with a smile: "the beam of this Council hall is so strong, I'm afraid it must be at least five level wizard to do it? It costs a lot of aura to condense into real things. It's not worth the loss! "

The old beggar nodded and said, "although what you said is reasonable, it's not the real reason."

"I'd like to hear about it." Chen Hui said immediately.

"The real reason is that things can't be changed for a long time." The old beggar explained: "no matter what kind of sorcerer you are, you can restore your aura just like an adult, and even if the sorcerer doesn't do this, when the sorcerer dies, you can restore your aura when the sorcerer is alive."

Hearing the old beggar's words, Chen Hui nodded silently and said, "return to heaven and earth!"

At this time, there is no saying that the law is still in heaven and earth.

When Chen Hui said this sentence, the old beggar's eyes appeared amazing light, said: "adult this words, extremely accurate."

After saying this, the old beggar turned to pick up the coin and said, "my Lord, what is most lacking at this time is not grain, but metal. Therefore, to make money from metal, you don't have to worry about counterfeiting."

Chen Hui nodded and said nothing more. In the history of the world that Chen Hui said, even if people's lives were good, metal was also the most scarce material.

After all, there was no advanced science and technology in ancient times, so there were great technical problems in mineral exploration.

In addition, even if a metal mine is discovered, the technology of mining and smelting metal can not be compared with the modern society of science and technology.

The old beggar continued: "if I guess it is good, the currency must be measured by weight, not the face value that adults have said before!"

"You are right, sir." Rabbit warrior immediately interface said: "it is measured by weight."

Hearing this, Chen Hui immediately asked.

Through the story of the rabbit warrior and the explanation of the old beggar's conjecture, Chen Hui understood that because of the scarcity of metals, there is no need to worry about counterfeiting. To calculate the value of money by weight is the most reasonable way.

The most important thing is that the five languages are customized together, and the currency must find a way that can be measured together. By weight, the currency can be easily realized in the five nationalities!

Of course, the weight unit at this time is different from that of the modern society where Chen Hui came.

However, if the weight unit is common to all five groups, it can ensure the currency to be common.

"I see!" Chen Hui nodded silently and said, "we have more or less understood the situation of Wangcheng. Maybe you can't imagine it, but the world I came to is more prosperous than Wangcheng. Therefore, I have a more accurate understanding of the situation of Wangcheng. In a word, the gap between the capital and Wangcheng, It's far beyond the gap between the capital and the original ethnic settlement of the Lord of the city! "

With these words, Chen Hui looked at the rabbit warrior and said, "from tomorrow on, you will begin to teach the words you have learned. After that, you will immediately return to the King City. This time, you need to thoroughly understand the price of the King City!"

"My Lord, what is price?" The rabbit warrior asked.

"It's to find out the money in your hand, how to convert it, how much money you need for a bag of grain, how much money you need for a pair of shoes, and so on, and write down everything in detail!" Chen Hui said, "I'm leaving the capital tomorrow. I don't know if you'll leave when I come back. I told you in advance."
