Stamping is a fairly common processing method in later generations, and many products in daily life are inseparable from this simple and inexpensive production process. However, it was quite difficult to replicate this technology in the seventeenth century, because neither pneumatic, hydraulic nor mechanical power could be manufactured, and the only thing that could be borrowed was artificial power.

Song Yi took the design drawing and looked at it for a long time: "Sir, all the alloys you asked me to make before were for this moment, right?" ”

Jiang Tian didn't intend to hide it from him: "Yes, I thought that such a laborious project could be avoided by still using the casting method, but now it seems that we will also carry out the development of the stamping machine in advance for our own currency in the future." ”

"But ......" Song Yi frowned and looked at the design again: "If this kind of machine can be built, it can indeed save the time of minting coins." But our previous methods are not impossible, haven't they all minted coins for thousands of years? ”

"That's right! For thousands of years, we have used coinage, but there are too many people in the world who will mint it, just find a small workshop as long as there are materials who can mint private money, which is definitely a loophole for the national economy, and the reform we want to carry out in the future is to avoid this situation, at least for the time being, the people can not imitate the coins made by this process, and the proportion of the alloy is not in our detail, which is an indispensable condition for the upcoming financial reform. Jiang Tian yawned and then rubbed his neck, which was the consequence of not sleeping all night to draw drawings.

Ever since Jiang Tian said the word reform, Song Yi knew that he couldn't ask any more, and this was not something he should know. The drawings are accurate and marked with detailed figures, and there are more detailed exploded drawings of some key components, although the structure seems simple, but according to the text of some notes above, it is not easy to achieve. If these things are realized, maybe it will indeed be as Jiang Tian said, as long as the copper plate is provided, the coins will be produced like flowing water. And all of them seem to have been carved by the hands of master carvers, so this set of equipment is also within the category of secrecy.

Anyway, the specific development had to be handed over to Song Yi, and Jiang Tian rushed back to the city after adding a return to the cage. When he returned home, he finally cleaned up the sludge accumulated in the past two days, and Youlan, who wanted to take advantage of his bath to make a surprise attack, saw his bearded appearance, and forgot the original purpose, and instead helped him carefully groom up. After a qiē was cleaned up, Jiang Tian finally regained the image of the white-faced scholar he used to be.

"You're back, sir." Xinyue frowned and complained: "In the past few days since you left, those craftsmen who repair houses have been knocking and beating, and there is no time to be idle, I went to ask them, but I told my employer that I should hurry up and work while you are not at home, otherwise it will affect your rest when you come back." ”

Jiang Tian couldn't laugh when he heard it, the delay in the emotional construction period was caused by this reason, Song Yi was afraid that the civil engineering would disturb the quiet, so when he was at home, they did some odd jobs, and they began to demolish and renovate when I was not at home. This can be regarded as Song Yi's concern for himself.

"Okay, I'll go talk to them and let them hurry up and get the work done before the Chinese New Year. By the way, how are those two widows doing? ”

As soon as she mentioned this matter, Xi Yun, who was joining in the fun, shook her head: "Brother, you don't know, those two sisters were trembling at the beginning, and they didn't even dare to eat enough, but Sister Xinyue didn't starve them because they took care of them." When I saw everyone, they were all respectful, but their teeth were too dark, so they couldn't have any disease, right? ”

As soon as Jiang Tian heard this, he imagined in his mind the tranquility of a snow-white face revealing a row of big black teeth: "No, it seems that their aristocratic women are popular to dye their teeth black and use it as beauty, maybe they also learn to wear makeup like that." ”

"I see...... Xinyue nodded: "It's just that we can't communicate because of the language barrier, but I will do my best to teach Chinese." ”

"Then it's up to you, I may have to live in the workshop for a while in the next two days, and then you will have to take care of the family."

Jiang Tian knew very well in his heart that no matter how detailed his drawings were, he couldn't expect Song Yi to be able to make qualified things according to the drawings, so he would definitely have to go back to command after the matter in the capital was resolved. The main reason is that the time limit given by the predecessor emperor is too tight, and he did not leave a buffer time for himself at all, I don't know if those people who went to other provinces to find ore have good news back, and he found a problem when he beat it with a hammer in the workshop, that is, the current steel does not meet the standards of mold manufacturing at all, and it will be damaged after repeated use more than a dozen times, and the life is really a bit short for things that need to be used for a long time and a large number of times, but fortunately, they have replaced the copper alloy with ordinary binary brass, and the flexibility and plasticity have been improved a lot, that is, the wear-resistant process dù has dropped greatly, but he also has a solution to this, and when the time comes, he will imitate the recovery standards of the residual coins of later generations, and also set up a set of residual coin recovery mechanisms. Early the next morning, Jiang Tian rushed to the post house without even taking care of eating early, as the emperor's special envoy, Fujiwara was going back to Japan, this is the official timetable will not be postponed because of their agreement with Jiang Tian, he will also bring back two copies of the national letter that have been stamped with a jade seal, so that the emperor can sign and sign and send back another copy for keeping. So Jiang Tian had to come to the post house early with a batch of rushed pattern coins.

"This ...... Is this the coin that adults minted for us? Fujiwara's eyes were straight when he was holding the pattern, he never thought that the coin could be so exquisite: "The skilled craftsmen of the Celestial Empire are really extraordinary, and I am reluctant to spend such beautiful money." ”

Jiang Tian thought to himself, what have you seen, can you admire this like this? Of course, he didn't say that these were not minted, and besides, if the Japanese people were like you and collected their own currency instead, then my business would be very profitable: "Brother Fujiwara doesn't have to be like this, as long as you can bring copper in the future, you can have as much money as you want, but if I want to say that I want to mint money for you first, I have to say a lot of words." ”

Fujiwara, who heard the sound of the strings and knew the meaning of elegance, of course understood what the other party was saying: "Lord Jiang really kept his promise, and we Japanese will also keep our promises, seeing the copper money you brought this time, I can explain to His Majesty the Emperor when I return to China, and I will naturally thank you here." ”

As long as you can bring more copper and silver, to be honest, it doesn't matter if you thank me or not, Jiang Tian thought so mentally, but there was a very interesting expression on his face: "What did Brother Fujiwara say, you and I are friends with each other, this little favor is just a gesture!" ”

The two sides also talked nonsense about the long-standing friendship between China and Japan, unanimously denounced and condemned the historical issue of Toyotomi Hideyoshi's unscrupulous attempt to invade and occupy Korea, and conducted in-depth discussions on strengthening exchanges between the two countries. In short, there will be a bunch of nonsense and a bunch of useless things.

Seeing that the time was not early, Fujiwara brought the topic back: "Lord Jiang, I have been thinking about it for the past few days, when Toyotomi Guanbai sat in the well and watched the sky in a vain attempt to challenge the Celestial Empire, it was because our two countries have lacked contacts for many years, I have an idea, if we follow the old story of the Tang Dynasty and send students to China in the future, won't this kind of thing be avoided?" ”

Jiang Tian then understood why the other party was talking so much, feelings were in ambush here, although sending Tang envoys sounded good, Jiang Tian was worried that Japan would learn some unnecessary things, you must know that the little devil is thirsty for knowledge and can learn anything. But on second thought, Japanese people are bullying the weak and afraid of the hard. As long as your own strength is strong enough, he will never dare to have a bad heart. And he is not a vegetarian on his side, maybe after he learns the four dissimilarities of the Central Plains, he will also be infiltrated by our soft power, just like the United States instilled values in later generations, cultivating a group of self-righteous but only American minions! Thinking of this, he is relieved, some industrial secrets are not something you can learn if you want to learn in a small Japan, our Celestial Empire's cottage strength is so strong, some things are not a plausible understanding, the higher the industrial starting point in the future, without the machining and machinery manufacturing industry in the Central Plains, you will always be a role that provides raw materials and sweatshops.

Jiang Tian, who pretended to ponder for a while, nodded: "What Brother Fujiwara said is extremely true, but this matter can only be decided after I tell His Majesty, fortunately, in the future, there is no hurry to open a port and trade between you and me, and you also happen to report to the emperor, and the two sides will discuss it." ”

Fujiwara, who received this answer, was overjoyed, and now his status in the court will be raised to a new level, and now there are still many people in the country who have never forgotten the old things of the Tang envoys in the past. It seems that Jiang Tian's line can't be broken, and it will work if he kowtows to the emperor more than me.

Fujiwara stood up, and then respectfully bowed to Jiang Tian in accordance with the customs of the Central Plains: "If this matter can be accomplished, Brother Jiang will make great contributions, and my country will be grateful." ”

Sent away Rory's fujiwara, this guy has to go to Tianjin Wei to settle down on the return trip and then rush to Dagukou to take a boat back to China, but it is different from the quiet appearance when he came, this time it is a beautiful gong umbrella cover to enjoy the standard of foreign guests. Bao Ke Zhengli, who was on his front and back feet, did not have this treatment, but King Ji also gave back some gifts in his personal name, which was regarded as giving them a little face. In the Central Plains, except for the Song Dynasty, the rest of the dynasties actually did not recognize the title of the Japanese emperor, and usually used words such as Wawang or Japanese king instead, and China has not accepted the other party as a junior brother so far, so it is necessary to compare the standard of the same level, and a prince will come forward to give the other party a gift to the general, which is also the diplomatic reciprocity emphasized by Jiang Tian some time ago. If the king of Joseon comes, he will be on an equal footing with the king of Ji at most, and he will be a vassal when he sees the emperor.

Maybe the task was completed too smoothly, or the other party didn't care at all. When Jiang Tian designed the coin, in addition to leaving the small characters of "Made in China", at the same time, he did not write the name of the emperor anywhere, so he simply could not find the royal imprint. Anyway, little Japan also uses the same set of calendars, and the other party doesn't care. And because the emperor has been an ornament for a long time, it may have lowered the vigilance of the shogunate. However, Jiang Tian's actions are very meaningful, first of all, it weakens Japan's national characteristics, and the use of Chinese as inscriptions also makes the boundary between the coins of the two countries very blurred, coupled with the use of unified raw materials and processing technology, it is really difficult to say what is the difference in their ability to pay. In fact, these two coins were used for a long time, until paper money became the mainstream instead of metal money, and Japan even planned to settle settlements entirely in Chinese currency. It was only for various reasons that it was not implemented in the end.

Jiang Tian didn't take a car on the way home, but walked back slowly, thinking about how to transform those international students into staunch Chinese believers, in addition to making them feel the huge gap between Japan and the Central Plains, it is best to let them marry a Chinese wife, anyway, those who can come to China are not idle people, they should be either nobles or the children of officials, and it is not too painful to marry. After decades of intermarriage, the Chinese in Japan themselves can't figure out how to calculate the blood, to see if he can turn the sky around. That is, those women who are used for intermarriage must be carefully selected, preferably under 1.6 meters tall, so as not to cause genetic modification to cause a significant increase in the height of the Japanese. Jiang Tian's idea is dirty and don't care about it, his concern is not unreasonable, and then it caused the height of the Japanese aristocracy to be generally higher than the nationals, and the natural sense of superiority is getting stronger and stronger, which once triggered a quite fierce peasant uprising two hundred years later, even if it was suppressed in the end, but the aristocratic power was also dealt a huge blow, plus many Japanese ethnic groups in China supported the domestic revolution, and finally led to the demise of the feudal system and became a complete constitutional monarchy. It was also at that moment that Japan could be considered to have entered the ranks of modern nations.

When he was walking, he accidentally heard a burst of music, this music also made him feel quite familiar, because this is the music he copied from the later generations, and then look up, there are two alleys almost home, surrounded by some wind and moon places, then this music is naturally someone is practicing, stop and listen for a while, although the technique is already very skillful, but the artistic conception of the music is not thoroughly understood, belongs to the kind of mechanical repetition. At this time, he remembered the past when he first accepted Zhao Zhi as an apprentice, in fact, it was only half a year later, but at least this kid was already able to support his mother by his own labor. In addition to working for Boss Zhao to earn a little money, he can also get some rewards when he talks about cross talk, plus eating at his master's house, there are not many places to spend money, maybe in a few years, this master will also consider finding a family for this kid, after all, if you are not married at the age of twenty in this era, you will belong to an older youth.

Thinking of this question, Jiang Tian couldn't help but think of himself, it is said that he is now a very popular minister, and there should be an endless stream of people who come to ask for relatives, but until now, no one has told him about this problem, it is not that he doesn't want to directly accept those girls who lean on the Red Mansion, but according to the situation of this era, even if the court doesn't care about his father in the countryside, he will not tolerate his son to find a kiln sister as a fate. As for the emperor, it can only be regarded as an exception, due to the lack of heirs of His Majesty all the year round, only one prince is still born to the mother of the current country, this mother is expensive and the emperor doesn't care, so that a Qinglou woman can become the queen, but when it comes to his son, if he wants to do it again, he will definitely be opposed by the ministers. Some things don't change right away if you want to. As for who his future wife is, he doesn't bother to think about it anymore, as long as he can tolerate these hard-working women like Xinyue, you will be a saltless reincarnation and I will endure it.

I didn't know that I had just walked into the house, but I saw Song Yi sitting in the living room waiting for him: "Sir, you are back, we tried to make according to your drawings, but we found that we couldn't understand the sizes you wrote on it!" ”

Jiang Tian then remembered that he was used to marking metric units, and there was indeed no similar size in this era, and some places required precision to the millimeter level, which made it even more difficult for Song Yi.

"This is indeed a problem, it seems that we still have a long way to go......" Jiang Tian sighed, he almost forgot the processing level of this era, such an accurate manufacturing technology is too difficult, and there are not even more accurate measuring tools, the national unit of measurement is still using the system of the Ming Dynasty, and I don't know what the emperor who crossed over is doing every day? Books are on the same track as the Wenche, which is the characteristic of the Great Unification Dynasty, but this predecessor has always been too concerned, anyway, the system of the Ming Dynasty can make do with it for a while. This led to a problem in the current research. For a long time, contrary to the habits of Indians, we have a rather insufficient understanding of the microcosm, which is reflected in the size of the smallest unit of measurement in weights and measures. However, when it comes to precision manufacturing, it is difficult for traditional units to adapt to future use.

"Actually......" Jiang Tian was about to make up a lie: "I was negligent, originally for the sake of secrecy, I planned to use a new set of weights and measures, so that even if an outsider got the drawing, he didn't know what was written on it, but he forgot to explain it to you." ”

"New Weights and Measures!" Song Yi grew his mouth in surprise, and then looked around before asking in a low voice: "Your Majesty doesn't want to deny the old system of the previous dynasty, right?" ”

Jiang Tian didn't dare to falsely pass on the holy decree: "This ...... I don't know, but in the future, in our development, we must indeed use a new size measurement, otherwise the shape will be inconsistent, which will cause great trouble. ”

Next, he gave a careful explanation to Song Yi about the new weights and measures, that is, the metric units of later generations, but fortunately, Jiang Tian still remembered that the construction ruler of the Ming Dynasty was exactly thirty-two centimeters, so he explained that he added three feet a little more to count as one meter, and one cubic meter of pure water was considered to weigh one ton and so on. And so, in the midst of a bunch of lies, the metric unit that would later become the standard was born.
