After inspecting Zhuge's workshop, Li Su spent a few days inspecting the situation of other "industrial areas" around Dujiangyan and gave some rectification suggestions.

However, in comparison, Li Su doesn’t have much to say about the factory owners of the Yang Hong family, the Zhen family and other powerful families. Who made these wealthy businessmen not worthy of being a good party? It makes people feel uninterested in giving advice?

If Party B does not work hard to achieve 70% or 80% or 80% or just one step away, Party A just wants to curse a few words and asks for a few tips, but there is no way to curse it.

After all this, Li Su remembered that Zhuge Zhi had not finished the matter of Zhang Yi developing Shan Wenjia, so she was ready to go to Jianwei to take a look.

However, before leaving, he returned to Pi County first, handed Xu Shu to Deng Zhi, and asked Deng Zhi to arrange Xu Shu to be some adaptive work for his staff to understand the situation. Xu Shu was not a versatile person like Zhuge Liang, and had no talent for skilled craftsmanship. His specialty was a staff officer, so he should only focus on doing what he was good at. On the other hand, it was also because Xu Shu had just arrived for a few days and was not suitable to see those military secrets.

After arranging the personnel work, Deng Zhi had already prepared the Clippers and the escort for Li Su. Li Su brought some entourage guards down the Minjiang River and headed straight to Jianwei County.

Cai Yan has been out of confinement for more than half a month. She had been staying at home and had not gone out for half a year. Now she is getting better, so she begged her husband to take her out for a walk. Li Su thought about it and found that Jian Wei was also in the hinterland in the rear. She had been there two years ago and brought her wives, concubines and maids with her.

I was still traveling around the mountains and rivers, watching the river view playing the piano, Cai Yan and Zhou Yingqinse played "Life is only a few short autumns, and I will not stop until I get drunk." There were some other improvisations, and I was so happy to serve Li Su.

In just three days, the fleet passed Nan'an and arrived at the Jade Road. It soon arrived at the largest "heavy industrial zone" in Yizhou. Now the main heavy industries in Yizhou, including steelmaking, porcelain kiln, and salt boiling in fire wells, were concentrated in Jade Road County and Jiangyang County, the county seat, as well as Zigong County, which is east of these two counties.

As the intersection of Jinsha River and Minjiang River, with the development of Nanbarbarian trade today, Nanzhong specialties have been continuously transported to the hinterland of Yizhou, so the shipping industry is also very developed. There are hundreds of large ships and nearly a thousand small fishing boats on the dock of Wuzhou every day, and ferries come and go.

The population of Jadao County has soared from just 14,000 households to more than 90,000 households three years ago to 40,000 households and more than 200,000. There are a total of four or five thousand households, just dock workers carrying coolies and boatmen who are driving water from Pantan.

Cai Yan came here two years ago, but now he is back, and the fleet from far away has just approached the dock, and the prosperity and changes in front of him have surprised him.

The endless fleets and docks are still second, after all, there were also two years ago, but the scale is not that big.

The key is that there are dozens of large chimneys with black smoke that can be seen in the county town in the distance, which is a wonder that cannot be seen two years ago.

After all, on the ground of the road, there are more than a dozen new type of iron smelting furnaces that preheat air. In addition, the kilns for burning porcelain and the kilns for burning refractory bricks provide means of production, all require a large amount of coal, and black smoke is not allowed everywhere. In the eyes of the Han Dynasty people, a kiln is considered a super big company if it uses thousands of stones of coal a year.

(As mentioned earlier, the refractory bricks needed for steelmaking blast furnaces are acid refractory bricks, which need to be burned with bauxite, so the farming officials like Guoyuan and Zhang Yi have not figured out the formula yet and cannot be produced. However, the refractory bricks in the kilns that burn porcelain are alkali refractory bricks, which can be burned with kaolin. It is very common. The craftsmen have figured out themselves in the past few years.)

"How could it be so prosperous? How much steel and porcelain should be produced in so many chimneys?" Cai Yan couldn't help asking.

Li Su Aoran pointed with a folding fan: "Look at it, in the Guanghe period, when the demand for steel forging in the world was the heaviest, the imperial court produced only 4.5 million to 5.5 million Hanjin jin per year. Before we improved the forging technology, the entire Yizhou only had 700,000 Hanjin a year, accounting for one-seventh of the world.

But now Yizhou can produce 2.4 million Hanjin kilograms of iron a year, and this Yidao County alone has a production capacity of 1.5 million kilograms. The total capacity of other states in the world is still 5 million kilograms, which is only about 10% higher than that of Taiping. Now the iron production of Yizhou has reached one third of the world, which is equivalent to half of the sum of other states.

In addition, Changsha County in Jingnan was slightly smelted, and the South China Sea in Jiaozhou also produced a little. The two places combined to produce 300,000 jin. The Xidu Armory Workshop in Guanzhong was also an important town for the imperial court. The Guanzhong area could inherit 400,000 jin. The land under the rule of the king had a total of 3.2 million Hanjin iron production, and the other princes added only 4.3 million. In the future, Guanzhong and Nanhai County will also use the Yizhou method to improve the process and add 1 million jin jin smelting furnaces. The iron production under the rule of the king could easily exceed the sum of all other princes."

This is the power of epoch-making technological progress. Once iron smelting evolves from the chemical model of "solid and solid reaction" to "solid and liquid reaction", the total reaction efficiency rate will increase by more than two or three times?

This is a qualitative change. From the Han Dynasty to the early Tang Dynasty, the national iron production was always more than 1,000 tons per year, which was restricted by the techniques of the hundreds of refining methods. By the Song Dynasty, it was three to four thousand tons per year, and the gap was here.

Only when iron materials are so rich can the country be willing to make more money on iron farm tools. When making weapons, Zhang Yi no longer has to be content with steel breastplate, but dare to touch Shan Wenjia's mind. It is obviously trying to create more elite soldiers in the whole armor.

Cai Yan was proud and impressed by this terrifying steel output figure. When he looked at the black smoke from these big chimneys soaring into the sky, he couldn't help but feel excited and wanted to write a poem.

"Before black smoke rises, all industries wither, and after black smoke rises, all are waiting to be developed. When it soars into the sky, it will be a gift to the hardware."

Li Su was touching her forehead when she heard it, and she wanted to find a crack in the ground to drill it down. This is a shame in life. You must not record such a spicy chicken that is worse than even likable poems.

However, think about it, even in the 1950s, when industrialization was just getting better, there were poets singing hymns and praising the chimney. Westerners before Dickens did the same. When London first became the fog capital, he was proud of it and did not feel any shame in polluting the environment.

"Okay, say less, go and do whatever you should do. Wouldn't it be better to let Sakura play with you?" Li Su couldn't help but cover her wife's mouth.

Cai Yan: "Well, it's a bit bad when I talk casually, but I can still change the words slowly. Whoever writes the poem will be done in one go? Let's see if I change these words..."

Li Su: "It's not a question of words! This subject is not suitable for praise, so why bother writing these vulgar words? Don't write them down."

He felt embarrassed and left his wife to his concubine, and took his entrepreneurs into the city and went straight to the yamen to find Zhang Yi and others to work.

"For no reason, people kindly tried every means to praise him for governing the country and enriching the people, but they actually shouted at me." Cai Yan grabbed a handful of flowers inserted beside him, and twisted the stems of the flower and rubbed them into a ball to vent his anger.

There is no way, the two sides are not on the same channel, and the gap between the times is too big.

...

Li Su and his party quickly arrived at the city's general's office as the Left School Office. After receiving the report, Zhang Yi immediately came out to greet him, and repeatedly showed respect and goodwill to Li Su.

Who made Yudao now one of the military industrial centers in Yizhou? It is normal to set up Zuojiao here.

Li Su was not a fool, and he made a clear idea of ​​the purpose directly: "I learned from Ziyu that there is no room for power on the water truck, and there is no place to use it, and there is no iron material. I want to create a new armor. But after seeing the sample you tried, it is really unbearable to use, so let's see if there can be any improvement."

Zhang Yi was obviously an official who had good means in organizing production, but didn't know much about technology research and development. In addition, he used to cooperate with Li Su, so he was surprised when he heard Li Su say this: "Oh? You still understand the improvement of military weapons? The new military weapons here are all figured out by skilled and experienced craftsmen. Bei Zhi just encourages them with rewards and punishments, and he doesn't understand the principle very well."

Zhang Yi was quite modest in his words, putting himself in the position of a manager and knowing everything without saying that he could do it.

Li Su encouraged: "Your Shanwenjia's idea is correct. I saw that the mold was not well opened. Just optimize the geometric shape of the aphrodisiac and re-stamp it to ensure that the thread is tightly sewn, and it is still OK."

Zhang Yi said suspiciously: "But, the craftsmen just don't know what the shape, thickness, length and size of the armor should be made."

Li Su didn't say much to him, and just looked at him and asked Zhen Yao, who was following, to take out a few pieces of paper from his sleeve.

Li Su originally planned to discuss such a small matter slowly after he came, but in the last few days of rushing on the boat, because of boredom and the boat was very stable and unbumping, Li Su took out a wooden compass and a wooden triangle board and ruler, and used his own high-level geometric and spatial imagination to recall the occasional appearance he saw on his previous life, and made several pictures.

Now, just try it one by one and you will know which one is better.

As for the idea of ​​drawing, it is actually very simple. It is nothing more than to make sure to draw a bunch of honeycomb-shaped regular hexagons on the paper first, and then draw a piece of mountain armor and armor in the three regular hexagons of each group of font shapes to ensure symmetry in each direction. Moreover, the width of the herringbone strokes of the armor leaves should be exactly half of the hexagonal honeycomb grid. In this way, there will be no leaks in the process of "four pieces and three hexagons", and it will not be too wide to be inserted together.

The final thing is to fine-tune the hook shape at the ends of the three strokes of the Arzalea to ensure that they can hook each other and try to be as solid as possible without overlapping. This is also the only difference on several drawings of Li Su, because the herringbone strokes in the middle are the same, and they are strictly half of the width of the beehive hexagon, and there will be no difference.

Although Zhang Yi himself could not shoot, he could also tell whether it was good or bad. When he saw that Li Su's picture was drawn with a charcoal compass, which was very symmetrical and just the right thickness, he knew that it must be good. He quickly called the craftsmen to manually cut some tin sheets of exactly the same shape, try splicing, and then choose the one with the best effect to open the die and stamp.

Tin is a very soft metal and is very suitable for mechanical structure experiments. If you try it, which one is feasible and it will also avoid the waste of opening the mold in vain.

The craftsmen were also very serious and tried it out at once. In just half a day, they selected the best solution for the splicing of the Li Su drawings with the best degree of jointing.

"Your Majesty, the shape of the armor leaf in this fourth picture is the most suitable. The armor leaf and armor leaf overlap, even the needle cannot be inserted. Only the point where the three armor leaves intersect can barely insert the thinnest sewing needle, but the arrows will definitely not be shot in. Moreover, this armor will eventually sew a layer of leather on the back. At that time, these small three-pointed holes are just nailed to the leather lining with round-bottomed copper nail needles." The craftsmen praised the feasibility of this plan.

Zhang Yi was quite surprised and praised the envoy for his far-sightedness and omnipotence, and immediately arranged for the craftsmen to prepare stamping molds.

Li Su reminded: "It's not only a problem with the mold, but also a big problem for the water wheel forging hammer you use to process the armor leaves.

Although I don’t know much, I know that forging hammers require slow speed and strong force. If the impact is too strong, a thick piece of breastplate will easily break, so it needs to be stressed and slow, and slowly crushed. But stamping a nail piece requires fast and small force. The armor leaves are thin and small, and the force will not break even if they are strong. The demand is large, so we must try to speed up the production speed.

Therefore, when the water truck is matched with a high-speed forging hammer, it uses a rudder chain transmission system that reduces the speed and accelerating force. When the water truck is matched with a low-speed high-speed stamping hammer, it uses a rudder chain transmission system that accelerates the speed and reduces the force. The former has fewer rudder teeth on the side of the water wheel, and the latter has fewer rudder teeth on the side of the hammer head. You have not even considered these or universal issues, so you dare to start work casually. How efficient is this?”

Li Su's surprise and description in words seems difficult to understand, but in fact, anyone who has ridden a bicycle knows that the bicycle has more gear teeth on the pedal shaft and fewer gear teeth on the pedal shaft, so the pedal can turn four or five times on the wheel, which is an acceleration transmission.

Li Su had to change the forged large pieces to stamped small pieces, and also turn the big teeth into small pieces, so that they could be efficient.

Zhang Yi felt that the envoy made a lot of sense, and every word was gem, so he quickly arranged the experiment. It was too late to re-made the transmission rudder gears in a short time, so they used local methods to change the hammer head and the large and small rudder gears on the water axle, so that the gearbox multiples were reversed. For example, the speed of the original reduction was four times, and now it was four times faster, and the difference was sixteen times. After changing it, the movement speed of the stamping hammer head flew instantly, faster than a chicken pecking rice, like a sewing machine nodding.

With these guarantees, the "Shanwen Armor" can be basically created with confidence. Although the defense of the Shanwen Armor is not as good as the steel breast deck plate armor, the advantage is that it does not affect the activity and can be used on the shoulders, arms, abdomen, back and legs armor skirts. The elite soldiers created in this way have no defensive corners.

These two forging and stamping machines gradually matured in the early European Renaissance in history. The ones who were given up the force were forging large pieces of plate armor, while those who were given reduction and accelerated the force were stamping fish scale armor sheets and die-cast gold and silver coins.

However, there was no need for stamping money in ancient China, and no gold and silver coins were used, so it rarely thought of developing such machines.

The copper coins used in ancient China were bronze, and bronze was alloy. They were low melting point, high brittle and hard, and were easy to stamp and break. They were not as good as gold and silver ductility. If they were stamping pure red copper, it would be fine, but the problem of opening holes of copper coins must be solved. In the future, if the coins were cast by stamping, the holes of the copper coins must be cancelled, and then there would be no way to string them.

Li Su watched Zhang Yi use temporary measures to improve the hydraulic stamping machine, and there was nothing to press for the moment, so he had this lively thought: Can you use copper with higher purity in the future and reduce the proportion of tin, and reduce the lead a little less, so as to ensure that the copper becomes soft and easy to press, and then directly cast some large amounts of money with doubled content...

Of course, what he thought was not to steal copper and exploit the people by using a method like "straight hundred coins". If he made a "ten coins", it would at least have twice the diameter of the current Wuzhu coins, so that the area would be four times, and the thickness would be half, which would basically be equivalent to the amount of six existing Wuzhu coins.

Then considering that the square hole in the middle of the money is gone, and the amount is at least half, then there will be nine Wuzhu coins, and the cheap tin content is slightly reduced. When ten Wuzhu coins are total, it is definitely very credible. Once the money is big, the amount required will be smaller, and it will not be too inconvenient to not string.

Moreover, considering that other princes did not master the technology of die-casting coins, the new coins cast by Liu Bei's camp could have better anti-counterfeiting. Considering this bonus, even if a coin only contains eight coins at that time, it should be able to ensure credit acceptance with technical anti-counterfeiting and prevent the public from melting the money.

Because if the value of the money is exactly the same as the value of the copper it contains, then as long as the price of copper rises, there are other needs to be used, such as casting a bronze statue of Buddha and Taoism, the copper coins will be quickly melted and misappropriated, and it will also cause an extra round of fire consumption in vain.

Only by giving money to the technical anti-counterfeiting content and charging "labor fees" when processing gold and silver jewelry in gold and silver shops can people cherish the finished product and not waste their craft value in vain.

With the large copper coins that are made of die-cast coins, another advantage is that it is easier for the court and the people to accept gold and silver coins in the future, and other precious metals can also be used instead of directly weighing them.

There was still a little gold stock in the late Han Dynasty, and there was very little silver, but it didn't matter. Maybe you could mine Japanese silver in advance in this life. You can count on Mi Zhu. If you can't count on this, you will do it yourself if the world is peaceful in the future.

When Li Su thought of this, he thought to himself in a concluding remark: "The king will definitely agree with this matter, but now is not the time. After all, the emperor has the final say in the court, and the emperor is still there, so we can't hurry. Make some technical reserves first. At present, these fast stamping hammers are only used to make Shanwenjia.

As for the reason for both hole money and non-hole money, it is easy to start with Qin Shihuang’s decision on half a liang of coins. The reason why round copper coins need square holes is one is that they are easy to pierce, and the other is the misunderstanding of etiquette and law when the sky is round and the earth is the round and place.

If people's senses are abolished today, and Xu Shu said that Aliang proved in the debate of the sky in front of the emperor that "the sky is round and the earth moves around the sun". What other square holes are needed? The earth is not square anymore. This reason will definitely be passed after saying it. The new money is called "Huantian Money". Only the sky is round and there is no place."

Li Su quickly figured out a set of fallacies, which were logically very strict and self-consistent, and even he was complacent.

That night, when he returned to the inn on Yedao, Li Su wrote down his new imagination in detail and improved the philosophical theory behind it.
