As for whether China's iron smelting industry was ahead of the West or lagging behind the West before modern times, the Chinese metallurgical historians before Zheng Kezang's rebirth had this opposite and diametrically opposed cognition. (If you like this book, please collect it biquge.info) But even the "Ting" faction has to admit that at least in terms of metal wire drawing technology, China is far behind the West. Therefore, Zheng Kezhang decided to put the so-called "second fire" on the improvement and absorption of this technology.

"When I go back to the prison country, I haven't heard of any silk drawing." The officials of the Zheng Ministry of Industry and the craftsmen of the iron-smelting workshop are all southerners, and most of them are from Fujian and Zhejiang, so it is understandable not to know that the Ming Dynasty Internal Affairs Office specialized in the production of metal wire drawing. "But there are still craftsmen in the Ministry of Industry who can make zuò."

"Let's bother, Lord Liu arranged for the craftsman to demonstrate for Yu."

Zheng Kezhang demanded this, and after a while, he saw a human wire drawing machine composed of a wooden bench, a drilled iron mold and pliers placed in front of him, a craftsman with a big waist and a round waist drilled through the iron mold that was polished into a conical shape through the iron mold flat on the wooden bench, and then used pliers to clamp the sharp end and pull it vigorously, and then a metal bar that was much thinner than the previous iron bar was pulled out, and then a thinner drill hole was used to pull out a thinner iron bar until it was drawn into an iron wire of the size required by Zheng Kezang.

"How much wire can such a craftsman produce in a day?" Zheng Kezang: This is not a question but an obvious reproach, and he is obviously very dissatisfied with such production efficiency. "That's it, that's it, there's a sketch here, Lord Liu can try to make a one." Zheng Kezang's method is to use the method of pulley block to winch, in the case of the same initial steps, with animal power or water power, with a constant force to pull multiple strands of iron wire together together into shape. "Waiting to see the results??"

With these wires and rings, an ordinary armor craftsman, in the case of poor weaving level, can produce a chain mail with the top of the head and neck protection every two months, and wait for the future to be skilled, and can produce two collars or even more in a month.

Because all the weight of the chain mail is borne by the shoulders and brain, it can effectively protect the chopping of the sword and the piercing of the spear, and can also protect the shooting of the bow and crossbow at a certain distance, so although it cannot be compared with the Gothic or ultra-Gothic full-body knight armor that has been eliminated in Europe, its protective power is enough for the Zheng army to face the green battalion without armor, and compared with the double-layer cotton armor of the Eight Banners, although it is not as cheap and easy to produce, it is suitable for Taiwan, an area with a large shortage of cotton and cotton products.

"I saw the results of the trial production, and Lord Liu still has a few masters who have worked hard." The words of the superior will keep the people below busy for several months, but Zheng Kezhang is still very satisfied with the expected results. "Lord Liu knows how many catties of iron wire can be produced in a month by such a machine."

"If you go back to the prison country, if the supply of iron bars is insufficient, one wire drawing machine can produce 1,500 catties of iron wire a month." Seeing Zheng Kezang's eyes flickering, he thought that he had a member of the Ministry of Labor who was dissatisfied with the production quantity, Liu Tong, hurriedly explained. "The iron used for wire drawing needs to be tempered, and it cannot be drawn to the required size at one time, so "

"Fifteen hundred pounds?" Zheng Kezhang calculated that a collar of chain mail needs about twenty-five catties of wire, so that the production of iron wire for one machine per month can ensure the manufacture of at least sixty collar chain mail, which should be sufficient for the time being, and there is no more pig iron that can be used exclusively for wire drawing machines. "Then build two more, one of which is in reserve." Zheng Kezhang decided so. "The wire produced is fully supplied for the production of chain mail."

"No!" This time, Liu Tong's response was much more powerful than the one before he was asked to try to make a wire drawing machine.

But chain mail is only part of Zheng Kezang's improvement of the production of the iron-smelting workshop, and the next thing to do is the real focus.

"Alas! Donald Laosi, why don't you work hard in the porcelain kiln, why did you come to us? "In the Kasuga Workshop, which is one of the iron-smelting workshops of the Ministry of Industry, several grizzled smelting craftsmen couldn't help but laugh at the newcomers who were building on the side. Could it be that you didn't open a gang and came to us to cheat and eat. ”

"Li Wu, you Lao Tzu knows that his mouth is full of feces," although the chickens and dogs are busy over there, they have the spare energy to put their mouths on the cannon here. "Your Tang Ye is not empty of food and has nothing to do, but there is an order from the ministry to let us help you build a few hydraulic forging hammers, you just want to invite me to come, and I won't come to your place."

"Jian Guo, this hydraulic forging hammer, the minister also saw it back then, but the strong ones are slow, and the fast ones are light, and they are not suitable for building objects." Speaking of which, whether it is wire drawing or forging, it is actually not the task of the iron-smelting workshop, but Zheng Kezhang is inconvenient to always meddle in the arsenal of the Ministry of War, so he set up a small workshop in the name of trial in the iron-smelting workshop under the Ministry of Industry Yu Hengqing Officials. "Isn't it a bit of a waste to make such a big splash?"

"Waste?" Zheng Kezhang looked at Liu Tong and smiled. "Does Lord Liu know what Qingtang Qizi Jia is?" In fact, the Qizi armor did not come from the Qingtang region, but was a product of the Western Xia party members, known as the strongest armor of that era. "This kind of armor does not need to be heated at all when forging, and all of it is made with a hard hammer by manpower, do you think that the craftsmen of this domain have so much time and energy to forge this kind of armor?" Zheng Kezhang fingers the hydraulic forging hammer under construction. "But they can!"

Zheng Kezhang said in his mouth, but he was helpless in his heart, to be honest, to make armor, the 500-pound forging hammer is enough, but if you want to make a steel cannon with an overwhelming advantage in range, this forging hammer needs at least 10 tons or 20 tons. But it is by no means a simple matter to make a 200,000 jin fine iron forging hammer, not to mention that Dongning only has more than 100,000 jin of pig iron a month to be baked, there is simply not enough iron material to squander him, even if there is so much iron material and a steam hammer is made, but Zheng Kezhang does not have enough power to drive it - at that time, the hydraulic machine is no longer enough, and how to make a steam power engine is only to check the information on Du Niang to do paste and copy the hurdle that he can't cross.

Of course, Zheng Kezang's helplessness is only temporary, although he can't surpass the current level of science and technology, but even so, the application of cold forging armor and chain mail is enough to deal with all types of bows and arrows currently equipped by the Qing army, not to mention that he is also ready to hire craftsmen from Venice to teach Taiwan how to produce Zheng Jun iron armor (European plate armor) with a hardness of more than HV500 and toughness of more than 100J/cm2 and the use of an arc-shaped hard-shell structure, so as to resist the unsophisticated bird guns in the hands of the Qing army.

"Your Highness, with all due respect, the plate armor that was popular in the age of knights has lost its due role in front of the musket." Hearing Zheng Kezang's request, Stevenson, the new director of the Yingguili Commercial Hotel, made a very Westernized shrug. "Of course, there is a considerable part of the ancestral artisans in Venice who went bankrupt because plate armor was no longer in fashion"

"Master Shi," Zheng Kezhang cut off the other party's unfinished words, and only asked directly. "The owner of the museum only needs to tell Sù if Yu can invite him, if you can't do it, Yu Zi will ask for help from Macao, Luzon and even Japan, and they should be happy to see it."

Zheng Kezang's tone made Stevenson can't help but narrow his blue eyes, but Stevenson understands that the monarchs of the East have always been strong, and if they can't oppress the other party with stronger force, they can only do what the other party wants, and Britain is just a latecomer in East Asia, and he can't be tough at this point.

"Since His Highness insists, we will naturally not have money and not make money, but it will take time, at least a year and a half."

"Yes, it's still a year and a half to wait." Zheng Kezhang ordered someone to put a plate of silver ingots. "Here is a deposit of two hundred taels, and the owner has collected it." Stevenson counted it, and without asking anyone to weigh it, he set the silver aside. "That's it," Zheng Kezhang continued, looking at Stevenson, who had put on his usual smile again. "Wait a minute, let Lord Liu sign it for you, and Yu won't interfere. By the way, when will the black slave Yu set before arrive. ”

"Your Highness, it takes three months to get from Umbai to Mumbai, and it takes another month to get from Mumbai to East Africa." Stevenson explained. "Although the Muslim regime in East Africa originally had a market for the slave trade, and there was no need for our people to go deep into the mainland to arrest slaves, it would take ** months to come and go, so Your Highness is a little too anxious."

"The last one to depart during the sugar period," Zheng Kezhang calculated. "So, it's going to be the New Year?" Stevenson nodded. "Well, let's talk about it then." This matter was put aside, but Zheng Kezhang did not go to North Shanwei Island for just two things. "You still need a hundred sail-makers, can you help solve it?"

"It seems a little difficult." Stevenson smirked. "Unless we go to Europe to recruit them, we may not be able to gather as many as a hundred sail workers from all the European settlements along the route to India."

"I'm afraid the owner is exaggerating, right?" There was something in Zheng Kezang's gaze that made Stevenson feel uneasy. "How many European ships are there along the coast from Daming to Tianzhu? Isn't there a craftsman in every boat who prepares sails and sews? Will there be less than a hundred people in this? ”

"Your Highness, I'm afraid it's confused." Stevenson hurriedly explained. "Sewing and sail-making are not the same thing at all, making a European soft sail requires special skills, usually only available in European ports, and the only thing that can be done by those who accompany the ship is to mend the edges of the holes."

"Really? Yu had to go back and ask those Yichuan teachings. "Zheng Kezhang didn't fully believe the British." In addition, the domain also needs 10 craftsmen who can make zuò chiming bells and 10 craftsmen who can make zuò glass, can you help you find them one by one? ”

"This?" Striking bells and glass products were the stepping stones for Europeans to open up the Asian market, and how could the British give up this resource? "I'm afraid it's a little difficult."

"In that case, that's it." Zheng Kezhang understood that if he couldn't get it from the British, it would not be able to get it from the Portuguese, Spaniards, and Dutch, who were more entrenched in East Asia, so he put this thought away. "Then come for the rest of the stallions who sell twenty Andalusian horses, don't say that this can't be done."

"Please rest assured, Your Highness, the contempt side will do everything in its power."

"Well, I need ten more riders who can make four-wheeled carriages, and I also need"
