Bet on Li Jingsheng?

Li Er didn't even bother to laugh, he just waved his hand and ignored Li Yuanxing at all.

Betting on Hou Jun Ji to win, this is really a joke, don't say that Li Er doesn't believe it, even Hou Jun Ji himself doesn't believe it.

"That's it!" Li Er thought about it, no one should gamble on this, and beckoned to Gonggong Gao: "Pass the word on, just say that it is what I mean, Li and Hou are secretly competing this time, focusing on perfecting the rules of this military chess game, betting on two gold coins of the emperor, plus two jars of good wine." The rest of the people are not allowed to participate in gambling, they are not allowed to inquire about the details, and anyone in Chang'an City will be severely punished if they peep! ”

Li Er smiled and waved his hand after giving the order.

Li Jingsheng, this is not an accident. Li Yuanxing just engaged in this game, so he didn't have much interest in paying attention to the situation of victory and defeat. Playing this, it's really not as fun as a real-time strategy game on the computer.

After watching this competition in a game where only the emperor and the king of Qin were spectators, Li Yuanxing returned to Qinwangzhuang.

In the next few days, Li Yuanxing lived a happy life of eating, sleeping, and eating.

During this period, Li Yuanxing returned to modern times, and he was idle for four days, and the matter of medicine was still in the analysis stage of Shiyan room, and it would take a long time to mass produce it, and the medicine that Li Yuanxing brought back from Datang was handled by Li Lanshan, and Liu Mingxuan was famous, and Li Yuanxing did not need to do anything personally.

The whole thing is an idler.

Finally, one morning in Li Yuanxing, Li Liyuan, who was so excited that he almost went crazy, was dragged out of bed.

Looking at the oil stain on Li Liyuan's face, Li Yuanxing really couldn't think of it. This girl who likes cleanliness the most, and dislikes the workshop the most, will have an oily face.

"Your Highness!"

Li Liyuan opened his hand, and in his hand was a copper coin, and there seemed to be some copper coins with residual warmth.

Li Yuanxing didn't speak, picked up a pure white silk handkerchief and wiped the oil off Li Liyuan's face first, and at the same time ordered: "Don't take Princess Liyuan to bathe and change clothes quickly." After the order, Li Yuanxing said again: "Go and change your clothes first, let this king take a closer look at this new money!" ”

"Yes!" Li Liyuan nodded heavily, still maintaining an excited smile on her face.

Placing the copper coin on the silk handkerchief, Li Yuanxing gently grinded it.

The first thing to look at is not the pattern. It's the degree of smoothness. Li Yuanxing didn't want the money he made to have burrs or something. You must know that using a stamping machine to press money, in addition to the problem of stamping machine, ordinary people in Datang can't solve it, the most difficult thing is the coin tire, and the weight of the coin tire must be very strict to achieve an accurate weight.

It is not difficult to achieve an error of less than 0.1 gram.

The difficult thing is in the case of mass production. How to save the most effort. The most labor-saving situation can achieve an error of 0.1 gram.

The coin tires are light. The pattern of the coin will not be delicate enough, and the weight will produce an excess part, which is the burr. It is impossible to spend a lot of effort to clean up the burrs after the money is cast, and the slight ones are ground with a stone rolling machine, but if the burrs are too heavy, they will need to be polished manually, which consumes too much labor.

After grinding for a while, Li Yuanxing looked at the silk handkerchief carefully.

Ok, hardly any worn out feeling. Li Yuanxing nodded with satisfaction, walked to the lamp with the copper coin, picked up a magnifying glass and began to look at the copper coin carefully.

This copper coin is five coins, and it uses a farmer's template.

Li Yuanxing was looking at the ear of wheat very seriously, and the requirements for delicacy here were relatively high. After looking at the small patterns in that circle, Li Yuanxing has been hesitating about the patterns, because adding patterns requires a higher process, but if you don't add it, it is equivalent to reducing the difficulty of imitation.

"Well, it's not bad!"

Of course, compared with modern technology, the 1,000-ton stamping machine is the height of ordinary goods, and Li Yuanxing is already quite satisfied that Datang can do it to this extent.

Li Liyuan used to take a shower and change clothes for at least half an hour.

But just as Li Yuanxing was looking at the copper coin, Li Liyuan had already changed his clothes and ran over.

"Your Highness, the first batch of copper coins has been made, but all of them are five coins, and I heard that it will take a long time to change the mold. Your Highness, do you want to go and see it! Li Liyuan was very much looking forward to Li Yuanxing going to see it in person.

It was Cui Dunli's opinion to build the money casting workshop near Qinwangzhuang.

Cui Dunli thinks that minting money is not a trivial matter, especially this kind of unique Qin Wang money, which is difficult to manage in the mountains, and the mining area just digs up the silver, and there is no need to put the matter of minting money in the mountains, not to mention that Qin Wangzhuang was originally built on the mountain, so he personally chose a location and invited Li Chunfeng to come over and see the feng shui in person.

In fact, the location is not in Qinwangzhuang, but from the back gate of Qinwangzhuang to the southeast for another five miles.

This is a valley, originally a rocky beach, there are some caves dug by the rich families in the Western Jin Dynasty, dozens of caves dug in the stone mountains, and there are even a few thick ventilation holes that lead to the top of the mountain. The original cave was a little simple, but under the reinforced concrete of Qinwangzhuang, it has become very good.

Outside the cave, stone strips, cement, rebar, bricks, a row of two-story buildings were built, and the entry of the cave had to enter this heavily guarded courtyard before entering the coin workshop.

All four steam engines were installed in the cave, without using the original ventilation holes. Instead, the pipe was connected to discharge the exhaust gas from the entrance, and the craftsmen of Datang did a great thing that shocked Li Yuanxing, that is, the principle of using the later Sichuan hookah. The exhaust part allows the gas to pass through the water once and then to drain it.

When Li Yuanxing came to the coin casting workshop, there happened to be a handyman collecting the deep mud in the water tank.

"No black smoke, nice!" Li Yuanxing praised it.

"Your Highness, this mud is a good thing. The people in the cement mill want it, the people in the steel mill want it, and the Taoist priests want it. A few days ago, the master craftsman who repaired the bridge also wanted to. It is said that it can be used for piling, and it is a very haode thing. A man dressed as a scribe next to him said to Li Yuanxing.

Li Yuanxing didn't understand for a while, what is the use of this thing.

Li Yuanxing is not an all-rounder, so he didn't know that he had inadvertently helped the craftsman, and Li Yuanxing originally only said that he didn't like black smoke. I don't like it even more when the smoke blackens the leaves, making the workshop area dirty and black. So the craftsmen tried every means to control the boiler smoke of the steam engine.

In fact, this is fly ash, which is also of great use in future generations.

The people in the cement mill want it, because this can be added directly to the cement. The people in the steel mill wanted, because the ash was fine enough to be added in the process of turning sand, and what the Taoist priests found in it, Li Yuanxing didn't know, even the Taoist priests didn't figure it out, because they were studying chemistry!

Li Chun wanted. Because when he went to the cement mill together and asked for more cement. In this little secret, adding fly ash can make his bridge stronger, especially the piles under the ground.

And then. For Li Yuanxing.

His initial thoughts were. Let Datang learn to protect the environment earlier.

"Your Highness!" Someone else came up. Li Yuanxing turned his head sideways and saw that it was Cui Dunli, and nodded as a greeting.

"Your Highness, Your Majesty has discussed it with the Ministry of Households. They can't afford to pay more. But there are two workarounds, one is to exchange the silk for money, and many merchants are willing to collect it. And the content of the transaction is not money, but copper. Another way is that the household department directly pays copper, silver, and gold as military salaries to the Qin Wangfu, and the Qin Wangfu pays the military salary! ”

Li Yuanxing did not immediately say whether this method was good or bad, but asked rhetorically: "How much money can I pay a day?" ”

"Your Highness, please!"

Li Yuanxing walked into the workshop with Cui Dunli, and Cui Dunli also said at this time: "Your Majesty came here last night, and I also want to know how much money I can mint in a day. Now there are two stamping machines in operation, and according to the craftsmen, both have a pressure of 200,000 catties, and with a lever, it can reach a pressure of 8 million catties. ”

"Good!" Li Yuanxing followed Cui Dunli into the workshop.

The steam engine here is very small, and it could have reached a pressure of 100 tons, but the craftsmen of Datang are really good.

"Your Highness, there is still a need to increase manpower here, they can't keep up with the embossing speed of zuihou, they are already waiting for the material to work, and they want to reach the highest speed in another month or two!"

Li Yuanxing has entered the workshop, which is divided into four square areas.

The first is raw material processing, which is the most primitive coin tire work area, which is the largest and has the most people. A scribe is keeping track of how much copper and how much silver has been brought in today.

"Gold, silver, and bronze must be divided!" Li Yuanxing commanded.

Cui Dunli said on the side: "Your Highness, you can divide the workshop in another month, and this is also the reason why there are no gold coins, gold coins must be more strictly managed, and this will only be a copper coin workshop in the future." ”

Seeing Li Yuanxing nodded, Cui Dunli said again: "Your Highness, there are strict records of how much material is incoming and how many coins are out, and you can calculate whether there is a problem, of course, if there are a few coins, there is still an error." ”

The people of Datang are very simple, and the craftsmen used in the money casting workshop are all the most reliable in Qinwangzhuang.

And the consequences of stealing money in the money mill are very serious, and these craftsmen don't want their families to lose their livelihoods, nor do they want to lose their lives.

The second workshop is grinding and annealing, and here it is the real slow, the former one because of the large machine, so one or two breaths can produce a plate of thirty-six pieces from the high press, and then quickly change the plate, and another plate can be produced.

"Your Highness, the craftsmen of Yaozhou are designing machines for finger grinding, and the stamping machine is also researching new ones, hoping that a more powerful stamping machine with eighty-one pieces will appear."

Cui Dunli explained beside him.

It's easy to go down to the next workshop, just clean the coin tires before Zuihou's embossing work.

The embossing works extremely fast, although only one at a time.

But Wu Cao seemed to help the craftsmen get the conveyor belt and the fast-embossed gear set, and Li Yuanxing stood by the machine and watched his watch calculate.

Seventy-eight coins were paid out every minute, and I watched the money fall with a bang, and then a female worker arranged it neatly in a wooden plate.

"Your Highness, a hundred pieces per plate, this is a fixed number, easy to calculate. It's all counted, and it's also a record of who took the money from here. From the start of mass production two days ago to today, only four coins have been signed and received, and there is almost no error between the quantity and the feeding, which is not related to the original calculation of wear and tear!
