In fact, Wei Zheng is not interested in how to use money, if it is because of money, Wei Zheng does not recommend Li Shimin to use such a trick, hmm...... How could the dignified jade seal be used to make an IOU, uh, although strictly speaking, this is not an IOU.

However, this thing can control these nobles of the Eastern Turks, these nobles can influence most of the Turks, and when all their property is in the hands of the Tang Dynasty, what these Turkic nobles buy is naturally in their hands.

It can be said that in the next few decades, they will be very peaceful, and a few decades are enough for them to use enough gentlemen and population to completely integrate these nomads into Datang.

This means that it has huge benefits for the stability of Datang's frontier and for the development of Datang's national strength, if you think about it like this, then it is certainly worth using the jade seal of the country, well, this suggestion is good, Wei Zheng feels that he has to suggest Li Shimin like this.

"In fact, this idea can not only be applied to the Turkic aristocracy, for example, the various gate valve families of the Tang Dynasty can also be used, you can use the right to invest, the payment for the purchase of a certain commercial franchise, etc., you can directly use this offset, and even you can operate some real estate, such as planning for Chang'an City."

"With the dissolution of commercial trade in Datang, and with the prosperity of commercial trade, after the status of merchants is enhanced, Datang's commerce will continue to develop, in this case, Chang'an's east and west markets will inevitably be insufficient, so Datang can directly demarcate a place around Chang'an City, and carry out targeted and planned construction of this place."

"For example, if this place is built into a factory, no matter what trading house or workshop factory is, it will be put in this place, and then the trading house will be centrally managed, and the merchants from all positions in Datang will inevitably choose to come here to buy their own things."

"Then when the number of commercial banks is concentrated enough, the value of these lands will increase, and when the time comes, is it normal for a commercial bank to sell hundreds of thousands of yuan of land?"

"Then the land trade of these commercial aspects of the Tang Dynasty will be taxed, which is called transaction tax."

"This money can be used to pay these gate valve families in advance, don't be afraid that you can't pay it back, but the money of the gate valve family has already arrived in your hands, and you can use it directly."

"In addition, the Tang Dynasty will inevitably use troops in the northeast, whether it is Murowei or the future Goguryeo, the nobles who surrendered, they can all use such means to concentrate big money to do big things." Xia Zhu smiled and said.

Wei Zheng and the officials of the Tang Dynasty next to Wei Zheng were all in a cold sweat when they heard it, Wei Zheng was slightly better, he knew what the officials of the Han Dynasty were like, and he also knew that the officials of the Han Dynasty were all taught by Huo Gang, and many of their thoughts and behavior habits were different from those of the officials of the Tang Dynasty.

But other Datang officials can't, most of them are negotiating with the officials of the Han Dynasty for the first time, and this series of words makes their scalps tingle, who are they? ! Oh my God, are you selling things to make money and giving each other ideas?

The most important thing is that the other party's idea is not just made up, but also that kind of ...... As soon as you hear it, you know it's cloudy...... Cough...... It can't be said to be very yin, it should be said...... Not to mention the naked conspiracy, the most important thing is that it is too terrible.

They can't think of such a means, but the other party can think of a little lady who is only in her early teens? If this is after the other party has decades of officialdom experience, wouldn't they all be old foxes?!

"Minister Xia really deserves to be the minister of the Han Ministry of Commerce, and he is really proficient in this business behavior." Wei Zheng arched his hand at Xia Zhu.

"Minister Wei is polite, as a fraternal country, this is what we should do, after all, the better the development of Datang, the better the development of our Dahan will naturally be." Xia Zhu smiled and said.

"The suggestion that Minister Xia said, I can send it back to Datang through relevant channels and hand it over to His Majesty for decision, but I think it is very likely to be passed, if this is possible, then it should also be able to afford it, so Minister Xia said before about selling grain?" Wei Zheng asked tentatively.

Xia Zhu pondered for a moment, and then she said seriously: "Yes, but I want to know, what is the current price of grain in Datang?" ”

Wei Zheng glanced at Xia Zhu, he didn't believe that Xia Zhu didn't know the price of grain in Datang, but since Xia Zhu asked, Wei Zheng thought about it and said directly, "The price of grain near Chang'an is currently about 350 Wen a stone, in the Jiangnan region, the grain price may be slightly cheaper, about 300 Wen, and the grain price in Henan Province, Hexi Corridor, and even the northern region has reached about 400 Wen to 600 Wen a stone." ”

The area of Datang is too large, and the grain price in the whole country must not be the same, even in Dahan now, the grain price in the whole country is not the same, but because of the protection price of the official purchase, the lowest price will not be lower than the official price.

In fact, the official price is similar to the price of the earliest food stamps used in the days of cash-for-work, and the current price is still 4 cents per kilogram of grain.

Converting the price of grain near Chang'an in the Tang Dynasty, it is actually about the same as that of Dahan, but it is slightly more expensive than that of Dahan.

Of course, the grain price in Chang'an is because Chang'an must be guaranteed by the official grain price of Datang, but there is no other place, to be honest, if it were not for the large number of Datang victims received by Dahan, the grain price of Datang is estimated to have at least doubled in many places.

"We can sell grain to Datang, but I think we can do it another way, didn't His Majesty Li Shimin allow the people of Datang to survive automatically? In this way, all the people of Datang who go to Dahan will support food throughout the process, and we Dahan are willing to set up food support stations along the road. In the early stage, Datang can help us give in advance, and we will make up how much we give. ”

"In addition, in order to thank Datang, we are willing to sell a large amount of grain to Datang, and sell it to Datang at a price of 3 cents per kilogram of grain." Xia Zhu said seriously.

"That's true." Wei Zheng almost stood up from his position, and he said with some excitement. As the main person in the negotiation between the two sides, Wei Zheng naturally has a very good understanding of the prices and weights and measures of both sides.

Dahan's penny is equivalent to Datang's penny, that is to say, this price is 180 Wen and one stone sold to Datang, even if the freight is counted, this price will not exceed 240 Wen.

Because the areas that Datang currently needs grain are the closest to Dahan, such as Jiangnan and other regions, there is no shortage of grain, so naturally there is no need to transport grain over.

And the official of Dahan sold this grain to Datang, to be honest...... In fact, it is sold at a loss, 1 point per kilogram, and how much you lose when you sell it.

Of course, the loss of this part of the money is in the hands of the Han people, so it is not so lost.

"Of course." Xia Zhu nodded affirmatively, "We can directly finalize this price." ”

"Then I don't know how much grain you can sell?" Wei Zheng took a deep breath and said directly.

"We sell as much as you want." Xia Zhu said calmly.

Wei Zheng was stunned for a moment, and other Datang officials were also stunned for a moment, although Datang said that it was not a catastrophe year, and there was not much food missing, but it was not a small number, and the most important thing was that Dahan dared to say how much he wanted to sell...... That's an exaggeration, isn't it?

"Minister Xia is not joking about this." Wei Zheng took a deep breath.

"No kidding, how much Datang wants, how much Dahan sells." Xia Zhu spoke in a calm tone and said lightly.

This time, all the Datang officials took a deep breath, of course they knew what this meant, which meant that the extra grain in the other party's hands could it be that there were millions of stones? Otherwise, why would they dare to say that?

However, what they don't know is that Dahan's grain income this year is ...... If you really want to calculate, it is enough for one-third of the population of Datang to eat a year's grain!

And it is impossible for Datang to lack so much grain, if Datang lacks so much grain, Datang would have collapsed a long time ago, so Xia Zhu dared to say how much Datang wanted, they dared to sell as much as they wanted, and more importantly, even if these grains were bought by Datang, they could almost catch up with next year's summer grain after the end of transportation, and next year's summer grain would only earn more grain.

At present, the grain of Dahan will not be planted too much, and the land area will definitely be expanded to other cash crops and spices, etc., after these things increase, it will be of great benefit to the westward expansion.

And Datang is this year, next year will be more difficult, basically after next year, the situation in Datang will also stabilize.

When the situation in Datang stabilizes, and Datang has popularized the Changle plough for more than a year, there is no shortage of food in Datang, so there is no need to plant so much food.

The next step is to diversify into food.

It is estimated that people in this world would not have thought that one day there would be a place where there would be too much food to eat, at least since this year, in fact, the people of Dahan have already eaten white flour in every household, and no one has eaten wheat flour mixed with bran.

Everyone eats white noodles.

"I understand, if that's the case, we'll need 500,000 stone grain in the early stage." Wei Zheng said directly.

"No problem, it's all new grain harvested this summer, and it can be transported immediately." Xia Zhu also agreed directly.

"Okay, then our previous armor will be ordered according to 20,000 sets, and we also need 10,000 war horses, which can be according to the price we set before." Wei Zheng also spoke directly.

"If you want to have a war horse, 10,000 can be delivered immediately." Xia Zhu directly agreed, the big man lacked everything, but there was no shortage of war horses. At present, the Han Dynasty does not count the war horses in the army, and there are more than 100,000 war horses.

And these war horses are all giving birth, and they found that the horses born of these war horses optimized by the spiritual spring water seem to be more excellent, and some ponies who are about to be close to one year old are already close to the war horses in the army, and when these ponies reach the age of two, they can definitely surpass the current military horses.

Naturally, this first old war horse will be sold.

"Then we might as well adjourn the meeting first, and then discuss some details, and I will expedite the situation here back to Chang'an for eight hundred miles, and return as soon as possible." Wei Zheng said.

"Okay." Xia Zhu also nodded, if eight hundred miles is urgent, the return of news from here to Chang'an will be four days at most.

Moreover, now Datang's 800-mile expedited is much stronger and faster than before, and the reason for this is also related to the increasing trade volume between Datang and Dahan.

Because of the terrifying number of caravans, there will be gathering points almost every 30-50 kilometers or so on the official road between Chang'an and Yumen Pass, and these gathering points are for merchants and caravans to provide rest, and they are all gathering points built by nearby people.

Or post stations, and with the establishment of these private post stations, many barren areas are not barren, in these post stations to establish official post stations is much simpler, and does not require a lot of money maintenance, in order to strengthen the connection with the Han Dynasty, Datang has established official information transmission points in all these post stations.

If according to the history books of later generations, the rule of post stations is one post station every 20 miles, but in fact, this number cannot be reached in Datang at all, to be precise, this number can only appear on the prosperous official road.

According to the historical records of the Tang Dynasty, there were only 1,639 post stations in the country during the heyday of the Tang Dynasty, one in 20 miles, and that was only 32,000 miles, that is, 16,000 kilometers. If you think about the area of Datang, 16,000 kilometers cannot spread all over the country.

What's more, the Tang Dynasty in its heyday, and the current Tang Dynasty, has just inherited the legacy of the former Sui Dynasty, not only has the post station not expanded, but even slightly reduced, so it is impossible to reach the standard of a post station in 20 miles, even in the heyday.

In the heyday of the Tang Dynasty, it was nearly 4,000 kilometers from Chang'an to Anxi Metropolitan Protectorate, and there was also Anbei Metropolitan Protectorate and so on. So 20 miles of a post station, that's impossible.

This led to the previous 800 miles of urgency, in these desolate areas almost had to be run by horses for 1200 kilometers before it was possible to change horses to find a post station, but now horses and heralds can be replaced every 30-50 kilometers, which means that these horses are running the best physical distance.

Then this speed is naturally much higher than the previous situation, and there will be no previous situation of running dead people or running dead horses.

After ending the negotiations between the two sides, Wei Zheng sorted out all the contents as soon as he returned, especially the things Xia Zhu said and some of his thoughts were all written into the letter, and then directly handed them over to the herald in charge of these things, and went straight to Chang'an at an expedited speed of eight hundred miles.

As the herald took the order, all Wei Zheng needed was to wait.

Jiuquan is about less than 300 miles away from Chang'an, and it is said that it is 800 miles to expedit, but now the speed of this news transmission is actually far more than 800 miles, because all the horses responsible for delivering news on this line are war horses from the Han Dynasty.

These horses can run at speeds of about 60 kilometers per hour, and there is no problem in running wild for an hour, not to mention that the average distance of these stations is about 30 kilometers.

And now it's not just about replacing the horses, even the post guards are directly replaced, and they are on the road overnight, and in about a whole day, a post guard has gone straight to Chang'an City, but when this post man arrived at Chang'an City, it was close to the hour.

"Eight hundred miles expedited! Eight hundred miles expedited! It's just that with the crazy shouting of this post guard, and at the same time, he kept raising a special token on his body, and the soldiers guarding the Chang'an City Gate directly opened the Chang'an City Gate without hesitation.
