Li Er didn't even bother to smile, he just waved his hand and ignored Li Yuanxing at all.
Betting on Hou Junji to win is really a joke. Not to mention that Li Er doesn't believe it, even Hou Junji himself doesn't believe it.
"That's it!" Li Er thought for a while, no one should bet on this, and called Eunuch Gao over: "Pass the word on, just say it's my intention. Li and Hou are competing for a secret this time.
, the important thing is to perfect the rules of this military chess game, bet two gold coins of the emperor, plus two jars of fine wine. The rest of the people are not allowed to participate in the bet, and are not allowed to inquire about the details. Anyone in Chang'an City who peeps will be severely punished!"
After Li Er gave the instructions, he smiled and waved his hand.
Li Jingsheng, this is not an accident. Li Yuanxing just played this game and didn't have much interest in paying attention to the outcome. Playing this is really not as interesting as real-time strategy games on the computer.
After watching the competition with only the emperor and the King of Qin as spectators, Li Yuanxing returned to Qin Wangzhuang.
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 was idle for four days. The medicine was still in the laboratory analysis stage, and it would take a long time to mass-produce it. The medicine Li Yuanxing brought back from the Tang Dynasty was handled by Li Lanshan. Liu Mingxuan was famous and also
There is no need for Li Yuanxing to do anything himself.
He is just an idler.
Finally, one morning in Li Yuanxing, Li Liyuan was dragged out of bed by the excited and almost crazy Li Liyuan.
Looking at the oil stains on Li Liyuan's face, Li Yuanxing really couldn't believe 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, and in her hand was a copper coin, which seemed to still have some remaining warmth.
Li Yuanxing didn't say anything. He picked up a pure white silk handkerchief and wiped off the oil on Li Liyuan's face. At the same time, he ordered: "Take Princess Liyuan to bathe and change clothes soon." After giving the instructions, Li Yuanxing said: "Go and change clothes first.
, let me take a closer look at this new money!"
"Yes!" Li Liyuan nodded heavily, with an excited smile still on her face.
Putting the copper coin on the silk handkerchief, Li Yuanxing rubbed it gently.
The first thing to look at is not the pattern, but the degree of smoothness. Li Yuanxing does not want the money he makes to have burrs or the like. You must know that using a stamping machine to press money, apart from the problem of the stamping machine that ordinary people in the Tang Dynasty cannot solve, in the end
The difficulty 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 zero tenths of a gram.
The difficult thing is how to achieve an error of 0.1 gram in the most labor-saving and manpower-saving situation under mass production.
If the coin tire is light, the pattern of the coin will not be exquisite enough, and if it is heavy, there will be excess parts, which are burrs. It is impossible to spend a lot of effort to clean up the burrs after the coin is minted. For minor ones, use a rolling stone machine to grind them.
However, if the burrs are too heavy, manual grinding will be required, which requires too much labor.
After grinding for a while, Li Yuanxing looked at the silk handkerchief carefully.
It was okay, and there was almost no feeling of being worn. Li Yuanxing nodded with satisfaction, took the copper coin and walked under the lamp, picked up a magnifying glass and began to look at the copper coin carefully.
This copper coin is five cents and uses the Nong's template.
Li Yuanxing looked at the wheat ear very seriously. The requirements for exquisiteness here are relatively high. Then he looked at the small pattern in the circle. Li Yuanxing has been hesitating about the pattern, because adding the pattern requires higher craftsmanship, but
If not added, it will reduce the difficulty of imitation.
"Well, not bad!"
Of course, compared to modern technology, where the thousand-ton stamping machines are ordinary goods, Li Yuanxing was quite satisfied that Datang could achieve this level.
Li Liyuan used to take at least half an hour to take a shower and change clothes.
But while Li Yuanxing was looking at the copper coins, Li Liyuan had already changed her clothes and ran over.
"Your Highness, the first batch of copper coins has been made, but they are all five cents. I heard that it takes a long time to change the mold. Your Highness, would you like to go and have a look!" Li Liyuan was really looking forward to having Li Yuanxing take a look in person.
It was Cui Dunli's opinion to build the money making workshop near Qinwangzhuang.
Cui Dunli believes that casting money is not a trivial matter, especially this kind of unique Qin King's money, which is difficult to manage in the mountains. It is enough to dig up the money from the mining area, and there is no need to put the coining of money in the mountains. What's more, Qin Wangzhuang is based on
It was built on the mountain, so I personally selected a location and invited Li Chunfeng to come and check out the Feng Shui in person.
In fact, the location is not in Qinwangzhuang, but about five miles to the southeast from the back door of Qinwangzhuang.
This is a valley, which was originally a rocky beach. There are some caves dug by wealthy households in the Western Jin Dynasty. There are dozens of caves dug in the stone mountain, and there are even several bowl-shaped ventilation holes that go straight to the top of the mountain.
The original cave was a bit simple, but with the reinforcement of Qinwangzhuang's steel and concrete, it has become very good.
Outside the cave, a two-story building was built with stone strips, cement, steel bars, and bricks. To enter the cave, you must first enter this heavily guarded courtyard and then enter the coin workshop.
All four steam engines were installed in the cave. The original ventilation holes were not used. Instead, pipes were connected to discharge the exhaust gas from the entrance. The craftsmen of the Tang Dynasty did a major thing that shocked Li Yuanxing, which was to use the Sichuan hookah of later generations.
Principle. The exhaust part allows the air to pass through water first and then be discharged.
When Li Yuanxing came to the coin workshop, a handyman happened to be collecting the deep mud in the water tank.
"There is no black smoke, not bad!" Li Yuanxing praised.
"Your Highness, this mud is a good thing. People in the cement mill want it, people in the steel mill want it, and the Taoist priests also want it. A few days ago, the great craftsman who built the bridge also wanted it. He said it can be used for piling, and it is very good.
Good stuff." A man dressed as a civil servant next to him said to Li Yuanxing.
Li Yuanxing didn't understand for a while what the use of this thing was.
Li Yuanxing was not an all-rounder, so he didn't know that he was inadvertently helping the craftsmen. Li Yuanxing originally only said that he didn't like black smoke, and he didn't like that the smoke turned the leaves black and made the workshop area dirty and dark. So.
Craftsmen tried every means to control the boiler smoke of steam engines.
In fact, this is fly ash, which will be of great use in future generations.
The people in the cement mill want it because it can be added directly to cement. The people in the steel mill want it because the ash is fine enough and can be added in the sand-making process. The Taoist priests found something in it. Li Yuanxing doesn’t know, it’s the Taoist priest.
They didn’t figure it out either, because they were studying chemistry!
Li Chun wanted to, because when he went to the cement workshop to ask for more cement, he discovered this little secret. Adding fly ash can 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 and saw that it was Cui Dunli, and nodded in greeting.
"Your Highness, I have discussed it with the Ministry of Household Affairs. They can't come up with more military pay. But there are two alternatives. One is to convert the silk into money. There are many businessmen who are willing to accept it. And the content of the transaction is not
Money, but copper. Another way is for the Ministry of Household Affairs to directly pay copper, silver, and gold as military pay to the Qin Palace, and the Qin Palace will pay the military wages!"
Li Yuanxing did not immediately say whether this method was good or bad. Instead, he asked: "How much can you pay in a day?"
"Your Highness, please!"
Li Yuanxing followed Cui Dunli into the workshop. Cui Dunli also said at this time: "I came here last night and also wanted to know how much money can be cast in a day. There are two stamping machines working now. According to the craftsmen, both
The pressure of 200,000 jins can be reached by leveraging the pressure of 8 million jins."
"Very good!" Li Yuanxing followed Cui Dunli into the workshop.
The steam engine here is very small and can originally reach a pressure of one hundred tons, but the craftsmen of Datang are really good.
"Your Highness, we still need more manpower here. They can't keep up with the final imprinting speed. They are already waiting for materials to work. I think it will take another one or two months to reach the highest speed!"
Li Yuanxing has already entered the workshop, which is divided into four areas.
The first is raw material processing, which is the most primitive coin tire work area. It 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 divided into separate houses!" Li Yuanxing ordered.
Cui Dunli said from the side: "Your Highness, it will be divided into workshops in one month. This is also the reason why gold coins are not minted. Gold coins must be managed more strictly. This will only be a copper coin workshop in the future."
Seeing Li Yuanxing nod, Cui Dunli added: "Your Highness, how much material is in and how many coins are produced are strictly recorded. We can calculate whether there are any problems. Of course, if there are a few coins, there will still be errors."
The people of the Tang Dynasty were very simple, and the craftsmen used in the money making workshop were all the most reliable in Qinwangzhuang.
Moreover, the consequences of stealing money in the money making workshop are very serious. These craftsmen do not want their families to lose their livelihoods, nor do they want to lose their lives.
The second workshop area is for polishing and annealing. This is where the speed is really slow. Because there is a large machine in the previous workshop, you can take out a plate of thirty-six pieces from the high-pressure press in just one or two breaths, and then quickly change the plates.
You can get another plate.
"Your Highness, the craftsmen in Yaozhou are designing finger polishing machines, and the stamping machines are also researching new ones. We hope that a more powerful stamping machine with a plate of eighty-one pieces will appear."
Cui Dunli explained beside him.
The next workshop is simple, just clean the coin tire before the final imprinting work.
The stamping work is extremely fast, although only one stamp can be stamped at a time.
But Wu Zhao seemed to have helped the craftsmen get the conveyor belt and the gear set for rapid imprinting. Li Yuanxing stood by the machine and looked at his watch to calculate.
Seventy-eight pieces of money were given out every minute. Watching the money fall down, a female worker arranged it neatly into a wooden tray.
"Your Highness, one hundred coins per plate. This is a fixed number and easy to calculate. These are all counted, and whoever takes the money from here is also recorded. From the beginning of mass production two days ago to today, only four coins have been
The person signed to take it away, there is almost no error between the quantity and the input material, and it has little to do with the originally calculated loss!" (To be continued. Please search Piao Tian Literature, the novel will be better and updated faster!)
