I have to say that when these craftsmen have enough skills, and let them have a certain culture, and understand part of the nature of affairs, the most important thing is to give them enough motivation, and the wisdom that these craftsmen burst out really made Huo Gang a little impressed.

Although it is still movable type printing, movable type has become the latest lead type, and because of the emergence of die forging, movable type can become very fine, not to mention, in addition, there are new improvements in ink and paper.

For example, the printing ink is blended with bio-glue or vegetable oil, and then the quality of the printing is tested, and the new letterpress printing and other technologies are all applied to the current new version of the currency.

Including Huo Gang's technology of printing invisible patterns between two sheets of paper has been developed. Of course, there is no way to compare you with the printing technology of later generations, but it is absolutely impossible for someone to crack it in this era.

The design of this banknote is a bit similar to that of later generations, the portrait uses Huo Gang's own head, which is drawn by his maid after Huo Gang gave him the method of sketching, which can be said to be very similar to Huo Gang's appearance.

After Anno looked at a few banknotes that could be considered works of art, he looked at the remaining very large banknotes in the box.

These banknotes are about two-thirds larger than the ones in your hand, and they have a more complex pattern and a long list of numbers of at least twenty digits.

And it is also larger, with 10,000, 20,000, 50,000, and the largest 100,000.

"Chief, who are these?" Anno asked with some curiosity.

"This is a bearer check." Huo Gang smiled and said, in fact, to put it bluntly, this thing is a silver ticket that was promoted to facilitate transactions. In this era, saving money and the like is more cumbersome, and it is even more difficult to deposit and withdraw money in other places, Huo Gang doesn't play so high-end, just just push out checks to them.

However, this check is not simple at all, first of all, the check must be a large customer to be entitled to apply, and each large customer's check is individually customized, and the check belonging to each large customer has a series of unique numbers.

Ordinary people don't know what this unique series of numbers is, but in fact, Huo Gang knows what it is, and this series of numbers actually represents a password.

For example, a book is regarded as a codebook, and the number on it represents a certain word in the book, so that this line of numbers can represent the information of a large customer.

First, it can carry out a certain degree of anti-counterfeiting work, and secondly, what about ...... In fact, this is also a source of intelligence, Huo Gang, who has watched TV dramas in later generations, knows very well, like the Qing Dynasty in the previous life, after the appearance of silver tickets, silver tickets are the best source of corruption and bribery.

After all, a few pieces of paper are too easy to carry in your arms, and your goal of carrying dozens of boxes of silver is too big, so it is not as convenient as a silver ticket. Then this string of numbers can be distinguished by the special staff of the bank to confirm which major customer it comes from, so that too much information can be provided.

Now there is no corruption and bribery in the Han Dynasty, but this is indispensable in the future, so Huo Gang will not announce these things to the public, and the people who know about the entire central money bank will only know such a secret if they are a very small number of die-hard people.

"Anyone who has a certain amount of money in our bank can apply, and we have customized it so that they can carry these cheques for exchange." Huo Gang said with a smile.

"It's a big benefit for trade." Anno's eyes immediately lit up, like the previous Dasui, and now some large-scale trade in goods in Datang is a very troublesome thing, sometimes just pulling money has to be pulled by dozens of wagons of money to trade, heavy, and unsafe, which has a very big impact on trade.

And this kind of check, any person can carry it away, which is naturally a lot more convenient.

"The coins have begun to be made, and all the food stamps in our territory can be replaced at any time, and the currency has also begun to be printed, and it will be ready in about half a month, and I will have people set up a money bank in all the cities of our Dahan, Yiwu, Loulan, Heishui, Industrial City, Yangguan, and Yumenguan."

"In addition, the original exchange point is not canceled, it still exists, but the currency exchanged is replaced, in addition, the negotiation with Datang, it is best to allow us to set up money banks in the three cities of Yumen Pass, Suoyang City, and Dunhuang County in Datang." Huo Gang thought for a while and said, "I will send someone over to take charge of it then." ”

"Yes! The subordinates understood. Anno and the others immediately nodded their heads in agreement.

"By the way, the ratio of a penny is the same as a penny." Huo Gang explained, "In addition, the matter of the gold standard can also be publicized." ”

"Yes!"

In fact, the currency of the Han Dynasty is no longer simply the gold standard, it is a bit like the monetary system based on bulk goods in later generations. However, for the time being, the two are in parallel state, in fact, the main purpose of the continuous supply of these large goods is to establish the credibility of the Dahan Central Bank.

Because at the beginning, people were suspicious of such a new business, and at this time, as long as they found that the Han was the same as before, and the currency could still buy enough goods, then they would not panic.

After all, ordinary people have limited money in their hands, and it is impossible for them to exchange for such things as gold, they are more interested in buying food and other living materials, and the people who need to exchange gold are big customers and big businessmen, and these people are more interested in making money than running on gold.

Especially when the gold standard did not appear in this era, they would not have thought of this for the time being.

After Anno and the others left Huo Gang's place, they discussed again, and on the third day after Li Shimin returned from Yumen Pass, he officially sent a special envoy led by Du Ruhui to officially invite the relevant officials of the Han Dynasty to Dunhuang County of the Tang Dynasty to conduct relevant negotiations between the two countries.

Li Shimin's decision can be said to have caused countless commotions in the officialdom of Guazhou in an instant, and Li Shimin's arrival in Guazhou had already made the locals more suspicious, especially when they were worried about the relationship between Datang and Dahan.

Because if the Tang Dynasty and the Han Dynasty fight, then Guazhou will definitely bear the brunt, and the current Guazhou can be said to be unprecedentedly stable, this stability does not mean that Guazhou has no problems, but they do not have to worry about the previous Turkic invasion and other issues.

Now Li Shimin is willing to talk to the big Han, which is naturally a relief for these locals, because these local rich families and gate valve families are actually very worried, if Huo Gang attacks, Dunhuang County will definitely be the first to be cleaned up.

And they, the local nobles living in Dunhuang County, were naturally the first to be unlucky.

The previous meeting with Huo Gang, except for a few people, no one knew, and now Du Ruhui officially "envoyed" Dahan, which means that Li Shimin has recognized the meaning of Dahan as a country, since Li Shimin has admitted it, then it is unlikely that the two sides will fight.

They were all relieved.

Du Ruhui's envoy was naturally very "smooth", after all, the bosses of the two sides had already exchanged views on the alliance between them, so the next negotiations were naturally logical.

On the third day after Du Ruhui's envoy successfully returned to Dunhuang County, Huo Gang sent the main negotiation team headed by Wu Ping, supplemented by Annuo and Mingyue, and Peony as the entourage, in addition to 100 cavalry of the personal guards.

The negotiation team on Datang's side was larger, with Du Ruhui and Gao Shilian as the main players, supplemented by the other five officials, and the two sides directly started negotiations.

In the first few days of negotiations, the main purpose of the negotiations was to "exchange views", after all, they had not "contacted" before, so naturally you put forward a little bit of this negotiation, and I raised a little, because Li Shimin was nearby, and the Yumen Pass, where Huo Gang was located, was only about half an hour away from Dunhuang County, and it could be reached by horseback for about half an hour.

There are two bigwigs here, and the exchange of opinions is naturally very fast.

So in the back, after Li Shimin and Huo Gang finalized the agreement on a formal alliance, the rest of the negotiations could be regarded as really unfolding, because the front was actually for others to act.

Whether it was the Li clan in Longxi, or the other gate valve nobles in Guazhou throughout the two weeks, they were actually very concerned about this matter, because they all knew that if the agreement was signed, it would mean the rise of these gate valve nobles!

Nonsense, how can they not know about the fact that the big man has good things?

It's just that the big Han didn't trade with them before, but only traded with the other five surnamed Qiwang represented by the Li family in Longxi, and they didn't dare to meddle casually, and now once the two sides open up on a large scale, this also means that they can also make money!

"Du Gong, I always feel that this matter is a little wrong." Gao Shilian looked at Du Ruhui a little depressed and said, he always felt that Du Ruhui and Li Shimin had something to hide from him.

Gao Shilian only came over later, the war on Li Jing's side was very smooth, and Tuyuhun originally added up to less than 100,000 people, just because they lived in the Tang Dynasty.

Once Datang made a move on them, they had no possibility of resisting.

Gao Shilian didn't need to deal with it later, so Gao Shilian naturally rushed to Dunhuang County to take charge of the negotiations.

"What's wrong?" Du Ruhan asked with a smile.

"The progress of this negotiation is also too fast, and it is not right to finalize these aspects of the negotiation so quickly, if this is a normal exchange, just from the beginning of the contact with the negotiation to today's step, how can it be completed without a month or two? Tell me, is there any agreement between His Majesty and Huo Gang? Gao Shilian asked in a low voice.
