Li Shimin, who met for the fourth time, received Yin Qingfeng very warmly.

"With your new farming technology, as long as it takes three to five years, my Datang will no longer be bothered by food! It's a pity that the people of the world don't know that the way to feed them is something that you, a young man, came up with. Li Shimin smiled and pointed out.

"Fame and fortune are just a passing moment, and the kid doesn't care."

"Oh? Tell me, what do you care about? I thought that Yin Qingfeng, who had been praised, would be humble or say something grateful, but I didn't expect Yin Qingfeng to come with such a sentence lightly, which hooked Li Shimin's curiosity.

"The kid made a poem the other day. This poem is written hundreds of years later, would Your Highness be willing to hear it? ”

"You can also write poetry? Hundreds of years from now? Well, sing it. ”

The title of the poem says: Remembering the past

Recalling the heyday of the early Tang Dynasty, Xiaoyi still has thousands of rooms.

The rice is fat and the corn is white, and the public and private warehouses are abundant.

There are no jackals on the roads of Kyushu, and the sun rises far away.

Qi Su Lu is in the car class, and the male ploughing and the female mulberry are not lost.

The saint in the palace plays the cloud gate, and all friends in the world are glue painted.

There has been no catastrophe for more than 100 years, and the uncle and grandson are happy and happy.

How can I hear that a silk is worth ten thousand dollars, and there is a field to sow grain and shed blood today.

The Chang'an palace burned down, and the temple newly removed the fox and rabbit hole.

I can't bear to ask the elderly, and I am afraid that I will leave from the beginning.

The small people are reckless and incompetent, and the court remembers the rank of Menglu.

China is prosperous and looks forward to our emperor, and sheds tears in the rivers and lakes. ”

Yin Qingfeng stole a passage from Bai Dada's two reminiscences, but slightly changed a few words.

Most of the meanings to be expressed after the changes have not changed, but the last sentence 'Huaxia is prosperous and looks forward to my emperor', how does Li Shimin understand this 'my emperor', Yin Qingfeng believes that he has his own interpretation, and this is exactly what he wants to see.

"Xiaoyi still hides thousands of families, rice flows fat, corn is white, public and private warehouses are abundant, and there are no jackals and tigers on the roads of Kyushu....... Fast! Write it down! I'll give you the ink! ”

"Uh~~ This... It's better for the kid to dictate, how about His Royal Highness's writing? ”

Li Shimin was stunned for a moment, and smiled awkwardly, "Okay, not bad!" Not frivolous, steady work, very good! Come, today I will study ink for you, just for this 'rice fat corn white public and private warehouses are abundant'! ”

"Then the boy was terrified."

Yin Qingfeng couldn't care about whether his thin gold body was hidden or not.

Since he wanted to show it, he would show his hand, so Yin Qingfeng stood there and took a deep breath, rolled up his sleeves and wrote.

It's a pity that Li Shimin's attention was on the content of the text, and he didn't notice how unique the thin gold body was.

When Yin Qingfeng finished writing, Li Shimin simply pushed him to the side, and leaned over to read while waiting for the ink to dry.

After feeling happy, Li Shimin got up and faced Yin Qingfeng, "Even if this poem is made for you, explain it to me." ”

The poem of the boy is based on the emotion of a poet three hundred, two hundred years, or even a hundred years later, and he lamented that the glorious Li Tang Dynasty in the past is no longer beautiful. The last two sentences are the boy's expectations for today's saints, not to have things that make future generations sad and weeping.

Since the Warring States Period, there has been no strife and war in this world, and I am afraid that it has only been more than 100 years together, and the large and small regimes recorded in the history books are not many. The emergence and fall of every dynasty or regime, not to mention the displaced people, but also the blood of those in power.

What is happening to the capital of the powerful East and West Han Dynasty? What about Liu's bloodline? Chang'an, Chang'an, long-term stability, but which dynasty has done it? The boy is not talented, and he is willing to contribute to the long-term stability of Datang. ”

"Food for thought! Thought-provoking~~~~" Li Shimin stood there with his head tilted and his eyes blankly posed at a forty-five degree angle.

"I know, in addition to telling such a poignant verse this time, what you want to say to a certain person will never be just those just now, let's talk about it now." Li Shimin, who came back to his senses, said in a deep voice.

Yin Qingfeng, who had been standing with him for a long time, first bowed and then said loudly in high spirits: "The previous Qin, Han, Jin, Sui, etc. were called dynasties, and the kid wanted the Tang Dynasty to be called the Tang Empire by the world and future generations!" ”

"The Tang Empire?" Li Shimin asked suspiciously.

"That's right! That's right! The Tang Empire! A mighty empire! An empire that will not let future generations cry! An empire that doesn't have to be remembered! Because! She is an empire that lasts forever! ”

Li Shimin muttered to himself: "The Tang Empire... A mighty empire... An empire that lasts forever...."

After coming to his senses, Li Shimin asked, "What is the difference between an empire and a dynasty?" ”

According to the classics of his predecessors, the boy reinterpreted the meaning of empire: first, there were great emperors; second, there is a sound government structure; third, there is a perfect law; Fourth, there is a vast territory; Fifth, there is a thriving economy; Sixth, there are people who obey the emperor's orders!

At that time, the people in Datang will live and work in peace and contentment, not to mention the abundance of grains and political harmony, and more importantly, the standard of my Datang is the standard of Siyi! The people of my Tang Dynasty are more respected than the barbarian kings! ”

Li Shimin's eyes lit up, and he asked urgingly: "Since you mentioned this empire, how can you do all this, do you have a careful strategy?" ”

"It takes a long time to do that. For example, in the territory, it will not work if there is not enough food and grass and strong and warlike soldiers. So is it enough to have enough food and grass? No, it's not enough. Even if the generals have conquered the territory, there will still be the people of our Tang Dynasty to fill and immigrate to the new territory. Only the people of my Datang live and live there, and that is the territory of my Datang.

If you want to have enough people, you need to multiply for a long time. In this long period of reproduction, the court can improve the structure of laws and decrees and government halls.

The kid secretly speculated that without thirty years, I am afraid that there will be no foundation or prototype of this empire. That's why the kid said it would take a long time. ”

After listening to this, Li Shimin was silent for a while, "Those who don't plan everything are not enough to plan for a while. Those who do not seek the overall situation are not enough to seek a domain; Those who do not seek the overall situation are not enough to seek a corner, and those who do not seek the general trend are not enough to seek a moment. You've got the overall situation and the general trend, what do you want to do next? ”

"Fortunately, it has been approved by His Royal Highness before, and the cultivation technology has been spread to the world. Now the kid still has a plan for His Highness. ”

"Tell me."

"The kid opened a shop in the West Market, this..."

"But it spread all over Chang'an a while ago?"

"Uh~~ Exactly..."

"I discussed it with others, but I didn't think it was the words you spread, but today I was sure."

"It's... In the face of such a powerful person, the kid can only make this decision to protect himself. ”

"What about your Immortal Residence?"

"The income of this Xianju Fang is okay, but there is a great inconvenience here. The boy thought hard for many days, but finally got something foolish. ”

Yin Qingfeng saw that Li Shimin had no intention of interjecting, and he continued: "I don't know if Your Highness knows how much money you have?" Xianjufang has a minimum of ten beds, and His Royal Highness knows how many of these ten are heavy? ”

"You mean ......?"

"The kid usually goes to the east and west markets when he has nothing to do, but the kid rarely buys things. It's not that I don't want to buy it, it's because it's really inconvenient. This inconvenience is not a problem of distance, but the inconvenience of carrying money. For example, in order to go to the Taste Building for a meal, the kid has to load a carriage of money to go out, and there is a carriage in the kid's house, what about ordinary people? ”

Only then did Li Shimin know that Yin Qingfeng was talking about things by excuse himself, "You go on." ”

"So, the kid came up with a compromise."

As he spoke, Yin Qingfeng walked to Li Shimin's bookcase, picked up a piece of paper and drew a copper coin shape with an outer circle and a square inside, with the word "open" on the top and the word "yuan" on the bottom.

"The kid's idea is: one, the shape of the copper coin can be large or small. Second, the copper coin can be marked with numbers. After speaking, Yin Qingfeng wrote on the left side of Kaiyuan: One, Er, Wu, and Shi, and wrote the word 'Wen' on the right.

"Specifically, the smallest copper coin is marked with one text, the slightly larger one is marked with two articles, the larger one is marked with five articles, and the largest one is marked with ten articles. Ten copper is equal to one silver text, ten silver is equal to one gold text, and ten gold text is equivalent to the consistent Kaiyuan copper coin.

In this case, the weight of money is only one-thousandth of what it is now; The advantages of this are: first, it is convenient for merchants to do business, and it is convenient for ordinary people to shop, and second, there is no shortage of money. ”

"How can your method be similar to Wang Mang's new money?" Li Shimin said thoughtfully.

"Your Highness Mingjian, the kid's idea was born out of the currency reform of the Great New Dynasty."

"But... Has this proven to be an unsuccessful change? Li Shimin asked puzzled.

"During Wang Mang's regency, it was also the most sluggish stage of the economy of the Western Han Dynasty. The money is concentrated in the hands of those dignitaries and family lords, and the people have no money to use, how similar is it to my Tang Dynasty at this time? Wang Mang's mistake is that he should not carry out four monetary reforms in just 20 years, but should come up with the most complete and perfect system after thinking it clearly, so that there will be no criticism. ”

"You mean, you're perfect?"

"First, Wang Mang has too many coins, and he actually uses turtle shells and shells for money; Second, the ratio of various currencies is unreasonable. For example, the value of the money itself is 30 or 50 times that of five baht coins, but Wang Mang ordered that it could be exchanged for 5,000 wen and five baht coins, which is extremely unreasonable. Third, Wang Mang's currencies have an advantage, that is, those currencies are of excellent copper, exquisite workmanship, neat writing, and delicate style.

The boy's suggestion is: first, my Datang's new coin has more changes in materials, such as: the weight of a Kaiyuan Tongbao is five baht, the weight of five coins is eight baht, ten baht is ten baht, etc., and silver coins and gold coins also change; Second, the gold coin uses the Qin seal, the silver coin uses the words of Wang Xizhi or Cai Yong and other calligraphy masters, and the copper coin still uses the word Ouyang Xun, but the workmanship must strive to be exquisite.

Gold, silver and copper were issued together, but copper coins must be circulated in large quantities, and gold and silver coins were collected by the wealthy. But if they want to collect, they will definitely take out the gold and silver at home and exchange it. As long as the wealthy people collected it, it meant that they were not opposed to the new money, and the common people could only accept the change in the face value of the copper coins. ”

Li Shimin thought for a while and asked, "Isn't that still a complete solution to the money shortage?" ”

Yin Qingfeng continued, "First, no matter what those rich families are, at least after the gold and silver in my Tang treasury are used to mint new money, there will be a lot more in terms of use; Second, now my Datang copper is cheap and gold and silver are expensive, which is actually because the annual gold and silver mining volume is not high. But my Tang Dynasty is thousands of miles away, and there must be a large amount of gold, silver and copper under the mountains and rivers that have not been discovered. If it is better for the king of Qin to order the officials everywhere to investigate with all their hearts; And those that are already being mined, the amount of mining is increasing. After a few years, when a large number of gold and silver coins were minted, the collection of the wealthy would be meaningless. In this way, the problem of money shortage has been fundamentally solved. ”
