I saw that Li Er was silent for a long time, and suddenly waved his hand and asked Zhao Yang and the others to go down.

In an instant, in the imperial study, only Du He and Li Er were left.

Li Er groaned: "Du He, this kind of thing, don't say it a second time, otherwise, you will cause endless trouble, now the various families of the Tang Dynasty have been established since the Han Dynasty, and they have been standing for hundreds of years, what do you think they rely on?" ”

Du He smiled: "It's nothing more than two things, money, people, if there is money, there are people, and if there are people, there are people." ”

"That's right, money and people are in the hands of the family, even if they are my officials, many of them are also members of the family, these people have stood for many years, intertwined, do you think, I don't want to reach out and ask the family for money? I tried it, and I saw at a glance the purpose of these people, they can give me money, but I will become their puppet......" Li Er said angrily.

Over the years, Li Erli has fought hard, not only to pacify foreign enemies, but also to start a war with the family one day.

Du He stood up, stretched his waist, and said: "That's it, if you want to make money, you kneel, if you want to stand and earn money, but it's impossible!" ”

"Then you just told me that the family is rich?" Li Er glared at Du He.

Du He smiled and said, "Your Majesty, I have a bold idea, I can not only stand, but also earn money." ”

"Oh?" Li Er was very interested, and hurriedly grabbed Du He's wrist, "Come and listen." ”

"Of course you can, but, Your Majesty, this matter of rebuilding the national prison is related to my Datang education and social stability...... Du He suddenly didn't want to go on.

Who knows, Li Er, who was still determined to rebuild the Guozijian, suddenly waved his sleeves at this time: "Okay, I'm ready." If you dare to tease me, you don't want to take half a step out of the imperial study today. ”

Du He sat down again, took out a pen and paper from the table, spread out the paper, and began to write and draw.

"Your Majesty wants money, it is nothing more than Kaiyuan Tongbao, silver, gold, other antiques, rare and the like, although valuable, but not the majority, want to take money from the family, the traditional way, one is to kneel down and beg, completely become a person of the family, the second is to rob, although now the Tang Dynasty soldiers are strong and strong, but if there are really many hands, I am afraid it will be a bloody war, the society is turbulent, the people are suffering, Your Majesty is definitely not happy to see this result, so, it will not work...... Now, there's a third way. ”

Li Er's eyes lit up suddenly, and he pulled over a chair and sat next to Du He, and couldn't wait to say, "Say it quickly, what can you do." ”

Du He smiled slightly, and drew two circles on the paper: "Exchange, use things, exchange all the Kaiyuan Tongbao, silver and gold in the hands of the family." ”

Li Er smiled: "Isn't it the same as not saying it?" If I have so much money, why do I have to go to the trouble of exchanging it with the family? Wouldn't it be better to use it directly for the benefit of the people? ”

Du He shook his head: "No, Your Majesty, what if I said that I would exchange a pile of paper for the silver in the hands of the family?" ”

"How is the exchange law? Do you think those people are stupid? ”

When Li Er heard it, he felt that Du He's method was unreliable.

Du He patiently explained: "Your Majesty, and listen to me, the paper I am talking about is not ordinary paper, but a kind of paper money that has been specially made, only the official can be produced, as long as His Majesty orders, from then on, the circulation of Datang is no longer Kaiyuan Tongbao, silver and gold, limited to everyone within a year or even half a year to exchange the silver money in their hands into paper money, expired and invalid, as long as there is official compulsion, when the time comes, Your Majesty thinks, will anyone not listen?" ”

As he spoke, Du He took out a red sun and put it in front of Li Er.

This red sun, Duhe has a box.

They were all drawn by lottery.

In later generations, this is a million, and it can be regarded as a small millionaire, but unfortunately in this era, it is worthless.

Du He introduced: "Your Majesty, this is a piece of paper and pen that the minister obtained before, such a piece is equivalent to consistent money. ”

Li Er picked it up and stroked it carefully, looking at every detail carefully, the more he looked at it, the more frightened he became, thinking to himself, I'm afraid that the best craftsman in the world may not be able to draw it.

His eyes widened suddenly.

This method is not special, it was used when the Tang Dynasty was established to create Kaiyuan Tongbao to replace the previous Sui Dynasty coins.

If it can really be promoted, wouldn't it be possible to exchange a large amount of real money with paper and pencil to get it?

However, Li Er was a little worried: "The people are naturally happy, this banknote is lightweight, easy to carry, and beautifully made, of course everyone is willing to use the banknote, but what if many people are unwilling to exchange it?" ”

"The world is the world of the people of the world, not the world of those big families, as long as the people of the whole world recognize the paper money, when the time comes, there are really stubborn people, then keep the silver money to live by yourself, besides, as long as the silver money in the world is in the hands of His Majesty, after the paper money is completely released, and then let go of the silver money, it is not a matter of your words." Du He waved his hand and said confidently.

Syllable.

Li Eryi slapped the table: "Okay, good idea, really good idea, Du He, I order you to start printing paper money from tomorrow and implement this method immediately." ”

Du He was speechless for a while.

"My Majesty, do you think this banknote is a printed book, if you want that, the banknote is not meaningless, the banknote must have two characteristics, the first is that in addition to the official, no one can copy it at all, and the second is that it has a strong degree of recognition, that is, it can easily distinguish the real from the fake...... With our current technology, we can't do it at all, so we need to study it more carefully. ”

It is not Du He who cracked down on Li Er, but in this era, one of the reasons why paper money cannot be implemented is that the technology is not good, just imagine, if the paper money does not have a high anti-counterfeiting technology, any person can copy it, what kind of chaos will it be like under the sky.

Li Er nodded: "That's right, I didn't hear that you have established a research and development center, hurry up and do this, as long as the banknotes are made, and when the time comes, I will give you a knighthood." ”

Du He smiled and said, "Your Majesty, the matter of marrying the princess ......"

"Let's talk about it when you become the prince of the country......" Li Er waved his hand and hurriedly drove Du He away.

A dignified generation of emperors, it was not easy to raise two daughters who were like flowers and jade, but Du He was worried about them all day long, and of course he felt uncomfortable.

"Your Majesty, don't worry, this is my design plan for rebuilding the country's eunuch, you can take a look at it first, by the way, I forgot to tell you that this plan was designed by me personally, and the final cost added up to less than 700,000 yuan, saving you 300,000 yuan for your majesty!"

Duhe threw down a few pieces of paper, turned around and left.
