Datang first village

Bet on Li Jingsheng?

Li Erlian didn't even bother to laugh anymore, he just waved his hands and ignored Li Yuanxing at all.

It was a joke to bet on Hou Junji's victory, let alone Li Er didn't believe it, even Hou Junji himself didn't believe it.

"That's all!" Li Er thought for a while, no one should gamble on this, and beckoned to Eunuch Gao: "Pass the word on, and say it's what I mean. This time, Li and Hou are competing in secret. The most important thing is to perfect the rules of this military chess game, bet on two gold coins of the Supreme Emperor, plus two altars of good wine. Others are not allowed to participate in gambling, and are not allowed to inquire about details, and anyone in Chang'an City who peeps will be severely punished!"

After Li Er gave the order, he smiled and waved his hand.

Li Jingsheng, this is not an accident.Li Yuanxing just played this game, so he didn't have much interest in paying attention to the outcome.Playing this is really not as fun as real-time strategy games on the computer.

After watching the competition in which 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. The matter of the medicine was still in the laboratory analysis stage, and it would take a very long time to mass-produce it. The medicine Li Yuanxing brought back from Datang was handled by Li Lanshan. There is no need for Li Yuanxing to do anything himself.

The whole thing is an idler.

Finally, one morning Li Yuanxing was dragged up from bed by Li Liyuan who was so excited that he almost went crazy.

Looking at the oil stains on Li Liyuan's face, Li Yuanxing couldn't imagine that this girl who likes cleanliness the most and dislikes workshops the most would have oil stains on her face.

"Your Highness!"

Li Liyuan opened her hand, holding a copper coin, there seemed to be some remaining warm copper coins.

Li Yuanxing did not speak, picked up a pure white silk handkerchief and wiped off the oil stains on Li Liyuan's face, and at the same time ordered: "Take Princess Liyuan to take a bath and change clothes." After giving the order, Li Yuanxing said: "Go and change clothes first , Let me take a closer look at this new money!"

"En!" Li Liyuan nodded heavily, with an excited smile on her face.

Putting the copper coin on the silk handkerchief, Li Yuanxing rubbed it lightly.

The first thing to look at is not the pattern, but the degree of smoothness.Li Yuanxing doesn't want the money he makes to have burrs and the like. You must know that using a stamping machine to press money, except for the problem of stamping machines that ordinary people in Datang can't solve, the most difficult thing is the coin tire. The weight of the coin tire must be very strict. to achieve an accurate weight.

It is not difficult to achieve an error within [-] gram.

The difficulty is in the case of mass production, how to achieve the error of [-] gram in the most labor-saving and manpower-saving situation.

If the coin tire is light, the pattern of the coin will not be exquisite enough, and if it is heavy, there will be redundant parts, which are burrs. It is impossible to spend a lot of effort to clean up the burrs after the coin is cast. However, if the burr is too heavy, manual polishing is required, which consumes too much labor.

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

It's ok, almost nothing is worn out.Li Yuanxing nodded in satisfaction, took the copper coin and walked to the lamp, picked up a magnifying glass and began to look at the copper coin carefully.

This copper coin is five coins, using the template of the peasant.

Li Yuanxing was looking at the ear of wheat very seriously. The requirements for delicacy are relatively high here.Then look at the small patterns in the circle. Li Yuanxing has been hesitant about the patterns, because adding patterns requires even higher craftsmanship, but if they are not added, it is equivalent to reducing the difficulty of imitation.

"Well, not bad!"

Of course, compared with modern technology, the thousand-ton stamping machine is of the technical level of ordinary goods, and Li Yuanxing is quite satisfied that Datang can do this to this extent.

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

But while Li Yuanxing was looking at the copper coins, Li Liyuan had already changed and ran over.

"Your Highness, the first batch of copper coins has been made, but they are all five cents. I heard that it will take a long time to change the mold. Would you like to take a look, Your Highness!" Li Liyuan was really looking forward to Li Yuanxing's personal visit.

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

Cui Dunli believes that casting money is not a trivial matter, especially this kind of unique King Qin money, which is difficult to manage in the mountains. It is enough to dig the silver from the mining area. It was built on a mountain, so I personally chose a location, and invited Li Chunfeng to come over and have a look at Feng Shui in person.

In fact, the location is not in Qinwangzhuang, but go out from the back door of Qinwangzhuang and go southeast for another five miles.

This is a valley, which was originally a rocky beach. There are some caves dug by wealthy families in the Western Jin Dynasty. There are dozens of caves dug in the rocky mountains, and there are even a few bowl-sized ventilation holes that go straight to the top of the mountain.The original cave was a bit simple, but under the reinforcement of Qinwangzhuang's reinforced concrete, it has become very good.

Outside the cave, stone strips, cement, steel bars, and bricks have built a row of two-story buildings. To enter the cave, you must first enter this heavily guarded courtyard, and then you can enter the coin-making workshop.

All four steam engines were installed in the cave, and the original ventilation holes were not used.Instead, a pipe was connected to discharge the exhaust gas from the entrance. The craftsmen of Datang did a major event that shocked Li Yuanxing, that is, they used the principle of Sichuan hookahs in later generations.The exhaust part allows the air to pass through the water once, and then discharge.

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

"No black smoke, not bad!" Li Yuanxing praised.

"Your Highness, this mud is a good thing. People in cement workshops want it, people in iron and steel workshops want it, and Taoists also want it. A few days ago, the master craftsman who repaired the bridge wanted it too. He said it can be used for piling, and it is very Good things." A man dressed as a civil official said to Li Yuanxing.

Li Yuanxing didn't think about it for a while, what's the use of this thing.

Li Yuanxing is not all-rounder, so he didn't know that he was helping the craftsmen unintentionally. Li Yuanxing originally said that he didn't like black smoke, and he didn't like the smoke that blackened the leaves and made the workshop area dirty and dark.So the craftsmen tried every means to control the boiler smoke of the steam engine.

In fact, this is fly ash, and it will be of great use in future generations.

The people in the cement workshop want it, because this can be directly added to the cement.People in Iron and Steel Workshop want it, because the ash is fine enough to be added in the process of foundry. Li Yuanxing didn't know what Taoist priests found in it, and even Taoist priests didn't figure it out, because they were studying chemistry!

Li Chun wanted it, because when he went to the cement workshop together and asked for more cement, he discovered that in this little secret, adding fly ash could make his bridge stronger, especially the bridge piles under the ground. sturdy.

Then, for Li Yuanxing.

His original idea was to let Datang learn to protect the environment earlier.

"Your Highness!" Someone came over again, Li Yuanxing turned his head to see that it was Cui Dunli, and nodded his head as a greeting.

"Your Highness, I have discussed with the Ministry of Households, and they have no way to come up with more military pay. But there are two workarounds. One is to exchange the silk for money, and many merchants are willing to accept it. And the content of the transaction is not Money, but copper. Another way is that the Ministry of Households will directly pay copper, silver, and gold to the Qin Palace as military pay, and the Qin Palace will pay the military pay!"

Li Yuanxing didn't immediately say whether this method is good or not, but asked instead: "How much 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: "I came here last night, and I also want to know how much money can be cast in a day. Now there are two stamping machines working. According to the craftsmen, both are A pressure of 20 jin can reach a pressure of 800 million jin through leverage."

"Very good!" Li Yuanxing followed Cui Dunli into the workshop.

The steam engine here is very small, and it can reach a pressure of [-] tons, but the craftsmen of Datang are really good.

"Your Highness, there is still a need for more manpower here. They can't keep up with the final printing speed, and they are already waiting for materials to work. I think it will take a month or two to reach the highest speed!"

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

The first one is raw material processing, which is the most primitive coin tire work area, which has the largest space and the most manpower.A scribe is recording how much copper and how much silver has been brought in today.

"Gold, silver, and copper must be separated!" Li Yuanxing ordered.

Cui Dunli said from the side: "His Royal Highness, there will be another month to divide the workshop. This is also the reason why there is no gold coin. Gold coins must be managed more strictly. 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 supplied and how many coin tires are produced. We can calculate whether there is a problem. Of course, if there are a few coins, there will still be errors."

People in Datang are very simple, and the craftsmen used in the coin casting workshop are all the most reliable ones in Qinwangzhuang.

Moreover, the consequences of stealing money in the minting workshop are very serious. These craftsmen don't want their whole family to lose their livelihoods, nor do they want to lose their lives.

The second workshop area is grinding and annealing. This is where the speed is really slow. Because of the large machine in the previous one, a plate of 36 pieces can be produced from the high stamping machine in one or two breaths, and then the plate can be changed quickly. Make another plate.

"Your Highness, the craftsmen in Yaozhou are designing finger-grinding machines, and they are also researching new stamping machines. I hope there will be a more powerful stamping machine with 81 pieces."

Cui Dunli explained beside him.

It's easy to work in another workshop, just clean the coin tires before the final stamping work.

The embossing works very quickly, although only one piece can be pressed at a time.

But Wu Zhao seemed to help the craftsmen get the conveyor belt and the gear set for quick embossing. Li Yuanxing stood by the machine and looked at his watch and counted.

78 coins are paid out every minute, watching the money rushing down, and then a female worker neatly arranges it in the wooden tray.

"Your Highness, a plate of one hundred coins is a definite number and is easy to calculate. It is all counted, and there is 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 sold. There is almost no error between the quantity and the incoming material, and it has little to do with the originally calculated loss!" (To be continued.)
