Next to Guanshishan Academy, there is a small barren mountain.

There are no mineral deposits or beautiful scenery on this hill, and the situation here has not changed until the establishment of Guanshishan Academy.

However, when Li Kuan was about to set up a mechanical workshop under Gewu Academy, Xu Jingzong thought about it and proposed this location to Li Kuan.

The workshop was built in the academy, which is not very suitable.

The workshop was built too far away from the academy and was not very convenient.

There is also a large open space at the bottom of this barren mountain, and it seems to be a good choice to enclose this place as the location of a mechanical workshop.

Today, the mechanical workshop has become a favorite place for students of Gewu Academy.

"Lord Wang, how about you take a look at this pattern?"

Li Kuan proposed to Li Shimin in the Daming Palace to establish the Datang Royal Bank, so naturally it was impossible to say that there would be nothing to do.

On the contrary, because this plan was proposed by Li Kuan, who is the founder and actual manager of the East China Sea fishery and an important shareholder of Datang Royal Bank, Li Shimin simply let Li Kuan take charge of everything.

Of course, it is necessary to have the household department arrange the necessary personnel to supervise.

Even if the eldest grandson Wuji didn't bring it up at that time, Li Shimin would have done it.

"The surface of the coin is still not clear enough, which will invisibly make everyone doubt the value of the gold coin."

Li Kuan is going to make gold coins or silver coins.

Naturally, it is impossible to use pure gold and silver to make it, and it is impossible to use enough gold and silver to make gold and silver coins one by one.

Referring to the gold and silver coins that appeared in modern times, making these currencies a symbolic thing is what Li Kuan hopes to achieve.

Of course, considering that in this era, everyone's acceptance is still relatively low, and Li Kuan is not so radical to come out with paper money.

However, it is still feasible to use a certain amount of gold and silver to create a currency with a fixed exchange ratio.

One dollar of gold can be exchanged for ten silver coins of one dollar.

A silver coin of one yuan can be exchanged for a consistent coin, that is, a thousand copper coins.

That's what Li Kuan wants to do now.

As for the gold and silver coins of two yuan, five yuan, and ten yuan, this will have to be done later, and it will be possible to succeed after everyone accepts this set of monetary system of the Tang Imperial Bank.

Otherwise, the gold content of ten yuan gold coins may only be several times that of one yuan, who would be stupid to use it?

"Lord Wang, this gold coin is already much clearer than the best Kaiyuan Tongbao on the market, and it is basically the highest level that the current minting technology can reach."

Dai Quan said with a sad face.

The casting level of the mechanical workshop, after the development of bearings and gears, has been greatly improved.

However, Li Kuan was still not satisfied.

If gold and silver coins simply play the original properties of gold and silver, it doesn't matter if the surface of the coin is exquisite or not, as long as the weight is enough.

However, if you want gold and silver coins to assume certain virtual attributes in the future, then it is best to do it well from the beginning.

"So, the king has an idea. Is it possible to make a mold where the gold coin is minted into a simple shape, and then pressed into the mold to make the shape we finally need. ”

Li Kuan thought of the stamping process he had learned, although the press of later generations is impossible to make now.

However, it is still possible to make a few pairs of simple molds, and then refer to the principle of the press of later generations, and make a simple stamping mechanism.

Even in order to make the life of the mold longer, Li Kuan even came up with the carburizing process.

"It sounds like it works, but I've never done it before, and I'll have to get the craftsman to try again. However, in order to press the desired shape in the mold, it is necessary to have sufficient and uniform pressure, which is more troublesome. ”

The copper coins of this idea are all minted, and it is really the first time that Dai Quan has heard of a plan like Li Kuan.

However, it sounds very innovative.

Considering Li Kuan's record of no failure in the past, Dai Quan did not have any doubts about the possibility of such a plan.

"In this way, we can divide into two groups, one group is responsible for the production of the mold, and the other is responsible for the production of this pressure mechanism. In order to verify the feasibility of this scheme, we can first carve a mold from hardwood and use pure gold to confirm the stamping effect of the gold coin. ”

In later generations, with the assistance of various advanced equipment, it was also very time-consuming to make a set of molds.

Although the molds needed in the workshop today are very simple, if they are made of steel, they will not produce results in a day or two.

Therefore, Li Kuan thinks that it is better to use hardwood to verify the feasibility of the plan first.

Anyway, the pure gold is soft enough, so there is no need to worry that the wooden mold will not be able to withstand it.

"Lord Wang, this is really a good way. It's just that this pressure mechanism has no clue for a while, and it is estimated that it will take a little time. ”

"Bring me a pen and paper, and I'll draw you a rough outline, and you follow that direction to improve the pressure mechanism."

At this time, Li Kuan was no longer clumsy.

In his previous life, Li Kuan visited a factory that produced stamping parts for automobile bodies and saw a variety of stamping equipment because of work needs.

What single stamping machine, even stamping machine, multi-station press, all kinds of tonnage are available.

Although the presses of each manufacturer are not the same, the mechanical principle of work is actually similar.

At this time, I didn't expect to make a complicated stamping mechanism, and I was fortunate to be able to make the simplest single stamping machine.

Li Kuan thought as he began to draw a picture.

The main components of the press are the working mechanism, the transmission mechanism, the operating system, the energy system, the support part and the auxiliary mechanism, but in this year when no one knows what electricity is, whether it is the energy system, the transmission mechanism, or the operating system, there is almost no need to think about it.

Li Kuan just drew the supporting part of a press and a simple working mechanism on the drawing.

To put it bluntly, the primitive stamping machine in Li Kuan's picture is basically four columns and a slider and some connecting mechanisms.

The slider is pulled up and down by hand to complete the stamping of gold and silver coins.

Of course, without an energy system, the pressure would have to rely on the weight of the slider itself.

In order to pull this slider up and down, the press is also accompanied by a pulley group next to it, and cooperates with a certain limiting mechanism.

Otherwise, the slider will be smashed directly, and the mold will probably be broken.

"Okay, that's the general principle, you first arrange for a craftsman to make a set of wooden ones, and see how the effect is."

In the mechanical workshop, there is no shortage of carpenters.

Especially after the carriage workshop was built, almost including the top carpenters in Chang'an City, Dai Quan just glanced at it and knew it in his heart.

"Lord Wang, don't worry, it can be made in three days at most."

……

In a blink of an eye, it has come to November 11 of the 11th year of Zhenguan, which is the first anniversary of Li Kuan's marriage. Of course, there is no such thing as an anniversary this year.

However, with so many eleven together, Li Kuan felt that it was still very special.

In addition, the temperature was close to freezing, and Li Kuan was not interested in going out, so he simply accompanied Cheng Jingwen and the little girl at home.

"Lord Wang, this little guy is a money fan, and he is so interested in gold coins."

Cheng Jingwen watched Li Kuan holding her daughter and playing in the special baby room, with a happy expression on her face.

This baby room was renovated by Li Kuan before his daughter was born.

Underfloor heating and wooden floors are standard, as are glass windows.

The most important thing is that he asked the carpenter in the house to make a bunch of various toys, even the slide.

Speaking of a baby room, this is a small children's playground.

Of course, the little girl, who is only two months old, basically doesn't know how to play anything, just lying on the floor, holding a few gold coins and playing.

She didn't want a Trojan horse, she didn't want a rattle, there were carved puppies and kittens, she wasn't interested in any of them.

When Li Kuan took out a few gold coin samples that Dai Quan had just sent this morning, she loved them very much.

What a little money fan.

"Hehe, she Aya makes too much money, and she needs a money fan to help take care of the house."

Although he knew that this was a child's unconscious preference, Li Kuan was also very willing to talk to Cheng Jingwen.

"But this coin is so beautifully crafted that I can't help but want to play with it in my hand."

Cheng Jingwen said as she picked up a gold coin.

This gold coin, the obverse is surrounded by six big characters of the Tang Dynasty Royal Bank, with a round word engraved in the middle, and a line of small characters in the eleventh year of Zhenguan below.

As for the back, there is only a simple one big word - Tang.

Originally, Li Kuan wanted to get Li Shimin's portrait up, but to make it clear, it invisibly increased the difficulty of mold carving.

This is not the most critical, the trouble is that in this era, the emperor is sacred and mysterious in front of the people, and the head of Li Shimin is engraved on the gold coin, and he comes and goes over in the hands of the merchants and the people every day......

As soon as Li Kuan proposed this idea, he was unanimously admonished by all the people around him.

In the end, Li Kuan also gave up this thought.

Fortunately, I wanted to pat Li Shimin's ass, but I almost slapped the horse's leg.

"Actually, I'm a little worried. This gold coin is so beautiful that some people are reluctant to circulate it when they get it in their hands, and keep it as a family heirloom. However, if it is too rough, it is difficult for everyone to accept. ”

Li Kuan knows very well that people in this age have a fanatical desire to save.

In the later dynasties where gold and silver flowed, many rich landowners liked to store gold and silver in clay jars, find a place to dig a hole, and store it in.

If money is not in circulation, it loses its monetary properties.

"Actually, has the prince ever thought about reducing the gold content of these gold coins a little more, so that everyone's idea of saving them without using them will be much smaller."

Li Kuan glanced at Cheng Jingwen in surprise.

She actually understands this truth?

If Wu Meiniang said this, he didn't think it was strange at all.

It seems that she really can't be treated as stupid and sweet.

"Well, that's an option, but you also need to take into account the situation of private coinage. If the gold content is low, the profit of private casting will become very high, which will stimulate people to take risks. ”

One gold coin for ten silver coins, and one silver coin for copper coins.

The same gold coin, if the gold content decreases, it means that less gold can be exchanged for more copper coins, and the benefits become great.

As long as the benefits are sufficient, no laws or punishments will work.

Otherwise, how can people say that if they want to know what industry is the most profitable, just open the criminal law and check it.

……

Just when Li Kuan was leisurely at home with his daughter, a significant battle took place in the distant Middle East.

The emerging Arab imperial army captured Ctesiphon, the capital of the ancient Persian Empire.

In recent years, there have been more and more Arab merchants walking in Nanyang, and even in Guangzhou and Quanzhou, and even Chang'an City can see their shadows from time to time.

Although the merchants of the Persian Empire were still the most common maritime merchants in the South Seas, without a powerful country to rely on, it is conceivable that their future would become uncertain.

This seems to have nothing to do with Datang, but slowly it will bring various impacts.

As the first fishery in the East China Sea to go out of the mainland, this change will be felt at the first time.

The situation in the South Seas is bound to become more and more complicated.

When Yu Chihuan and his entourage returned home, they had actually felt this subtle change.

Although they did not yet know that the Arab Empire had captured the capital of the Persian Empire, forcing the other side to retreat into a corner, laying the groundwork for its eventual demise.

However, several times along the way to the port to replenish fresh water and food, you can feel that the number of Arab merchants has increased compared to the time when they came.

Of course, with the heads of Wei Chihuan and Fang Yiai, they naturally don't think about it so much.

Anyway, in their opinion, everywhere the East China Sea fishing footprint goes, the meat can only be eaten by themselves, and others can drink some soup at most.

If anyone is not convinced, then the bed crossbow on the flying clipper ship can work.

……

In the west market of Chang'an City, a new spice shop was established at the beginning of this year, and the shopkeeper was Abdul, a maritime merchant from Arabia.

As one of the first maritime merchants to enter the Tang Dynasty, Abdul has his own shops in Guangzhou and Quanzhou, and last year, Abdul made a major decision to go to Chang'an City, the most prosperous city in the Tang Dynasty, to open a new spice shop.

Abdul has its own regular partners, and every year a steady stream of spices are transported from Nanyang to Datang.

To put it mildly, in Quanzhou and Guangzhou, he is the largest supplier of local spices, and his every move can affect the price of local spices.

Even among the maritime merchants in Hangzhou and Mingzhou, many people bought from Abdul's shop.

Either don't do it, or do it and do it to the best.

This is Abdul's philosophy of doing business.

From the beginning of planning last year to the opening of this year, Abdul's shop became the largest spice shop in the West Market on the opening day, accounting for more than 40% of the sales.

If you are an ordinary businessman, you must be very satisfied with this result.

But Abdul felt that it was not enough, and throughout the eleven years of Zhenguan, he continued to move, and he bankrupted several Hu businessmen.

The spices sold in the West Market were originally dominated by Hu merchants, and the influence of the Tang people was very weak.

As a result, Abdul immediately became a large player that accounted for more than 60% of the spice sales in the West Market.

What is the purpose of a monopoly?

Of course, the price has increased.

In just one month, the price of spices in the West Market ushered in three consecutive increases, smoothing out the decline in the previous months in one fell swoop.
