The appearance of the "Treaty of Friendship and Mutual Assistance of Friendly Countries" caused a great shock in Japan, and the emperor specifically acquiesced in the spread of the matter, which meant that the Japanese people could go abroad to work in the distant tropical regions of the South Seas, and for the shabby samurai had the opportunity to prove their martial prowess in a foreign land. Since the establishment of the Tokugawa shogunate, it has tightened its control over ocean trade and the major coastal vassal states, and the days when the poor couldn't stand it and could go to the Ming Dynasty to rob it, but also because of the appearance of Qi Jiguang and other cattle gradually became unfeasible, and later, let alone rob, it was a good thing that you were not robbed by Zheng Zhilong. Now that they had seen the light of day, the shogunate had not taken a position on the matter, so they could trade along the coast of China generously, although according to the treaty, other merchants and daimyo did not have import tax incentives from the imperial family and the shogunate, but it was not a big deal, it was better than guarding a bunch of decaying ships and doing nothing. To say that the happiest thing is to belong to the religious and cultural circles, they used to count on the Japanese to be able to snatch back a little of the Central Plains books and artworks, and now they can also come to the Middle Earth in a grand way, and after returning home, they can pretend to be in front of their peers.

It's not that the shogunate doesn't want to stand up and speak, but the general's young family elders quarrel over this matter, although Hoshina Masato has won the majority of the preferential share for the shogunate, and they can make a lot of money with this alone, but they don't know that this will weaken the influence of the shogunate, especially when they see the whole box of books brought back by Hoshina, these guys who can also read Chinese understand that even the collection of documents from all over Japan cannot be compared with these things, with Toyotomi Hideyoshi's previous experience, No one dares to be so arrogant as to think that treaties can be abrogated at will.

"Your Highness Baoke, what do you think of the armaments of Middle-earth during this trip to the Central Plains?" It was the elder Sakai Tadashi who spoke, and as the person who assisted the general, he was most concerned about whether this neighbor was strong and strong.

Bao Ke Zhengli thought for a while and said: "I didn't have a chance to get close to their barracks, but from the moment I went ashore, I could see that the port was guarded by soldiers, and along the way, whether it was Chengguan or the post house where we lived, there were also soldiers standing guard. ”

The Japanese called the musket an iron cannon, and there was a great development at the end of the Warring States period under the influence of the Dutch, but unlike the Japanese who later boasted, this kind of thing is not only limited in the number of equipment, but also unsatisfactory in power, compared with the shotguns of the Ming Dynasty, there are many inferiors, not to mention the muskets such as Lu Mi gun and Thunder gun. But this incident shocked a few people in the room, how much money is an army that uses muskets as its main equipment?

Baoke Zhengli seemed to remember something again and hurriedly added: "In addition to the iron cannons, they also have a lot of large barrels, and on the batteries in the port, I see from a distance that there are at least dozens of gun emplacements!" As for Beijing City, I heard that the officials of the post house said that they would not push out the big cylinder for maintenance, but there are at least dozens of giant cylinders in the head of Beijing! Then there is the fact that they are selling swords cheaply, in addition to the standard sabers of the official army, there are all kinds of other swords! ”

Saying that, Bao Ke Zhengli ordered someone to take a sword box, and after opening it, there was a common Longquan sword in the Central Plains: "This sword was originally worn by some warriors and scribes, although it is not as easy to use as our sword, but please take a look." ”

Baoke took out a piece of the sword and handed it to Sakai, who took it and just pulled it out slowly, and his eyes began to glow. The smooth and smooth sword does not have the pattern of a Japanese sword, but the mirror-like smoothness and slightly trembling sound indicate that this sword is a superior work.

"I heard that because the emperor of China used to smelt iron on a large scale, the swords of the Central Plains are no longer made of iron, and they are all made of steel, which is much lighter than our swords but very sharp. I saw their saber once, it was the standard knife that the officers were equipped with, the scabbard and the hand were rough, but the blade was also made of stainless steel, heavier than the one we used, not beautiful enough, but very practical, and it would be a great loss for both of us to chop. ”

Baoke Zhengli actually didn't know that although the officer's saber was also an official thing, it was mainly a decorative role, and the soldiers who really went into battle to kill the enemy used to imitate the military knives and bayonets of later generations, and the blade was short but powerful. As for the big barrel he said, it was actually the artillery we talked about, and it was also passed down by the Europeans back then, which is funny, but he guarded the country of invention of artillery, but went around half the world to get artillery technology. For the Japanese, it would be a great thing if anyone used artillery in a war, and if we compare it with the density of firearms in the Ming Dynasty, it is estimated that they are not even stragglers, compared with the Chinese Dynasty...... There is no all-firearms army in the world so far, so there is no comparison.

Sakai sighed and put the sword back into the scabbard of the shark skin: "So the current Central Plains is no longer the kind of court of the Ming Kingdom, and they really can't be provoked!" ”

In this way, the shogunate had no choice but to hold its nose and recognize the treaty, and declared that Sakai Port would become a trading port with China again, and that any merchant ship that wanted to trade with Japan would have to unload its cargo and pay customs duties at Sakai Port. Other daimyos, especially the Shimazu family in Kyushu, were very dissatisfied with this, which was tantamount to seeking the near and far. But they are not without workarounds, these guys in the Ming Dynasty actually occupied the Ryukyus, on the surface the king of the Ryukyus is still canonized by the Central Plains court, but there is still a group of Japanese on his head, the Satsuma clan invaded the Ryukyus in addition to opening up the territory, the main purpose is to find an agent for trade with China, which is why they occupy the string of small islands but do not claim sovereignty. In the past, the Ming Dynasty was too busy to take care of this bit of affairs in overseas countries, but the Chinese Dynasty opened up trade, and Ryukyu was also canonized by the new dynasty, so it means that it is much easier to trade from Ryukyu than to Sakai Port. This may have been unexpected by the shogunate.

According to the original historical development, since the death of Tokugawa Iemitsu, the Tokugawa shogunate began to decline, and the effect of the closure of the country will continue to push Japan into isolation, but this process is very slow, and if it is not for the bombardment of Edo by the Americans, the shogunate may not have fallen so quickly. In this time and space, due to the gradual failure of the retreat policy, the Tokugawa shogunate actually went to a small glory, but after the mineral deposits were basically exhausted, Japan's raw material economy gradually collapsed, and the cheap foreign grain severely affected the local agriculture, hastening the death of the shogunate, making the era of the return of the daisei a few decades earlier than another time and space. Later, it was simply transformed into an economic form that is good at tourism and service industry, and as for how famous their service industry is, this is a later story.

Just when the Japanese were preparing to recreate the scene of sending Tang envoys, Jiang Tian had a terrible headache. Although a lot of measuring tools were made on the fly, the craftsmen and the researchers were still used to using their own experience to make things, and even if you gave them a ruler, it would take a lot of effort to get these people to put aside the "just about it" mentality. That's not all, that kind of novel design also gave him a lot of trouble, these people don't understand the scale at all, they just think that the big parts drawn on the drawing are as big as they are, even if the size is marked on the top, but they can still get it wrong, the reason is that he doesn't know what the mm and cm written after the numbers mean. Not to mention allowing craftsmen to understand the decimal point.

Jiang Tian, who was anxious, sat in the room scratching his scalp, he hadn't taken a bath for several days, although the weather was very cold, but the house was very hot, plus he was in a hurry these days and those guys broke and crushed and explained, in fact, this oil sludge can grow food, he thought about it for a long time, and felt that it was not a way to go on like this, and he couldn't do anything he wanted to do so much, right? Besides, as long as the equipment is a little more complicated, they don't know how to read the drawings, and they come to ask this and that every day, and you just draw in detail, no matter how detailed it is, it's useless.

"Dexin, are we thinking of a different way?"

Song Yi also knew about these situations, but he didn't think it was a big problem, in fact, if it wasn't for Jiang Tian's too many requests, they wouldn't have had so much trouble making something before. But he also knows that there is a reason for Jiang Tian's strict requirements, everything that Jiang Tian presides over and manufactures can be said to be the most advanced in the world, and many whimsical ideas have opened the eyes of this young man who loves science, such as the brass hot rolling mill that is being done now, as long as the hot copper bar enters this machine, the final copper plate must be thin and uniform! He has figured out the design of the machine, in fact, the reason is very simple, just like the flatbread at home, use a steel roll to flatten the copper bar, and the finished product comes out after multiple rolling processes. And what is more advanced is that Jiang Tian took into account that manpower can no longer complete such a job at the beginning of the design, so he designed a power standard interface, whether it is a waterwheel, a windmill or animal power, as long as a set of transmission equipment is designed according to this interface, it can be used in various environments, of course, Song Yi does not know that this standard interface is actually for the preparation of steam power in the future. The problem is that because it is too advanced, Song Yi can imagine that this design can be used in many places, not to mention that as long as the spacing of the rolls is adjusted, the copper can be made. But such a delicate and extremely demanding material has exceeded the wildest imagination for his group of craftsmen, not to mention anything else, the gears of different sizes and shapes alone can make the most experienced old craftsmen complain, so Jiang Tian had to reopen the class to explain the principle of leverage to those researchers alone. This is not counting those rolls that are the most difficult to process, an iron rod made of steel requires the same thickness from beginning to end and the surface is absolutely smooth, every time Jiang Tian will take this special large caliper and measure it carefully, and the error must be less than 0.1 millimeter!

Thinking of these, Song Yi also had a headache: "Sir, should we put down such a strict thing first, anyway, there is no big problem with the copper plate being cast, first make the stamping machine you said, don't miss the major events of the imperial court." ”

Jiang Tian knew that this was a kind reminder, he didn't know that if it was just to make coins and do so much trouble, Song Yi would not understand the driving effect of this kind of national research and development project, if this hot rolling mill is really formed, then China's metal processing technology will produce a qualitative leap, and when those who are looking for ore come back, if they smelt qualified special alloy steel, they will be able to push the entire processing system to a new height. This time it was just a hot rolling mill developed from the origin of money, in fact, he still wanted to get on the lathe and boring machine, but because he found that the material was really not up to par and there was no suitable tool, I really don't know how some people who crossed the barrel can casually use a soil boring machine to cold-draw rifling?

"In this way, you first gather everyone together, let's focus on training for a period of time, the structure of the human press is much simpler, but the requirements for the material are not low, we strive to make the press before the New Year, as for the appropriate mold only to wait for the test of alloy steel."

"Alas......" Song Yi sighed: "It's only like this, I didn't expect that we couldn't do such a simple thing." ”

Jiang Tian was happy when he heard it: "You remember, the pursuit of industrial design is to simplify the complex, the fewer parts of two machines with the same function, the higher the technical requirements, such as our hot rolling mill, the whole equipment can not fit in a yard, if we have better power and materials, at least three rolling procedures can be reduced, how much material and cost can be saved?" ”

Song Yi nodded thoughtfully, he knew that what Jiang Tian said must be reasonable, although this equipment has not yet been successfully developed, but he has also seen the huge potential, as long as the machine can be started and operated, how many coppersmiths can be liberated from the heavy manufacturing process, as long as they buy the right thickness of copper skin, they can do whatever they want, and at the same time, how many craftsmen who make a career lose their jobs? If it were possible to reduce the number of parts of the equipment, wouldn't it crush the small-scale workshops that did not have an advantage, and everyone but the skilled masters would be unemployed. He didn't know that he had inadvertently glimpsed the power of industrialization, which was to make the handicraft industry almost die. If there is a steam engine in the future, Jiang Tian actually wants to build a cold rolling mill, combined with a steam-powered stamping machine, which is the last straw that crushes the traditional processing industry.

So, all the craftsmen and researchers were summoned to Jiang Tian's studio, saying that the studio was actually the hall of a landlord's house in the past, and the Academy of Sciences was afraid of freezing this detached expert, so he did not hesitate to add a layer of fire wall to the wall, and the principle was to move the fire kang to the wall, which played the role of soil heating under the premise of not affecting the appearance, and the disadvantage was that it cost coal, but fortunately, there were many small coal mines in the suburbs of Beijing, and the Academy of Sciences was naturally not bad for this money.

"There are no rules, you can't make a circle, today I once again emphasize the control of quality, you have to abandon the previous concept, the things made by the Academy of Sciences must be the best in the world......" Jiang Tian didn't have much nonsense, he had already been familiar with these people these days, he knew that it was useless to say how many big truths you said, these people may not be able to understand, but as long as the word royal in front of the Academy of Sciences is emphasized, and it is emphasized that it must be the best to make things for the royal family, it is more useful than how much theoretical knowledge is useful, as for how to improve the business quality of these people, That can only be successfully developed, with the actual effect to shock these elm pimples.

If those craftsmen who work for Jiang Tian are a kind of common people who are in awe of officials, especially if the other party is still a big man wearing a bullfighting suit. Then these researchers are a kind of admiration from the heart, some of these people are not young, they may have traveled all over the country with the emperor when they were in the palace, and some of them even Song Yi saw it and had to salute according to the generations of his sons and nephews, but when Jiang Tian criticized them mercilessly, the vast majority of people did not dare to refute at all, not only because Jiang Tian was the emperor's junior brother, but also because in front of this little generation, the craftsmanship they were once proud of was so worthless. Let's talk about the principle of leverage explained a few days ago, although the emperor has said similar things before, but it is definitely not as detailed as what this young man said, especially when applied to gears, so that they can see what it means to live and learn.

Because there is no lathe, so the development of the roll Jiang Tian adopted a stupid method, that is, on the beaten steel rod first to repair the general outline, and then on the human grinding wheel fixed grinding, this practice is not only inefficient, at the same time the precision control zhì is also quite difficult to grasp, Jiang Tian can only start from the improvement of the grinding wheel, try to use precision devices and mechanical fixation, abandon the traditional grinding method in the feeling of relying on the craftsman's fingers. Just like the development of the telescope last time, this is equivalent to rebuilding a set of industrial systems, and also allowing all those involved to initially understand the difficulty and standards of industrialization. Those who don't think much about the operator's craftsmanship, just look at whether you work according to the standard process, so that those workers who rely on their hands to eat feel the crisis, with the current set of equipment of the Academy of Sciences, even if it is only a short-term training apprentice, can produce basically qualified parts, the only difference between the old craftsman and those who usually work as slaves is what is the probability of scrap.

Song Yi, who also felt this way, couldn't help but ask: "Sir, do you mean that the industrialization you call is the ability to produce things in large quantities casually?" ”

Looking at this guy who realized it later, Jiang Tian had a feeling of hating iron and steel: "If not, what kind of industry are we still engaged in, you remember that in the future, the value of industry will exceed that of agriculture, and it will be the standard to measure whether a country is strong or not, although we have a lot of land and resources, with small workshops and small kilns that bloom everywhere, it seems that we can also obtain huge output, but in terms of fuel consumption and cost, it can't be compared with industry at all, and it seems that we can still maintain an advantage over the surrounding enemies for the time being, but think about it, Suppose Japan, the island country, has a few sets of equipment that we are developing now, then it can reach our current production capacity with less manpower and material resources, and then the huge country is not as good as those dwarves, but it is really embarrassing! ”

Is industrialization really that powerful? The answer is yes, otherwise Britain would not have become an empire on which the sun never sets, Germany would not have been able to start two world wars without many overseas colonies, little Japan would not have been able to create an economic miracle after the war, and China would not have been able to transform itself from a purely agricultural country into a world factory in 50 years. This truth is well known in the 21st century, but it is a fantasy in this era. Every technological advance is inseparable from the huge investment in basic science, and it took Europe more than 200 years to turn loose folk research into a state act, followed by a conquest of the world. As a traverser, whether it is Jiang Tian or Zhang Tao, they all know that there is a way to get closer, that is, the national linkage mechanism after the founding of New China, for a national project, the entire scientific research system and the factory must be unified and coordinated, which can make the original long research work into the fast lane, and the results can be seen in a very short time, but the shortcomings are also obvious, for a project, maybe other things that others are studying have to give way, or just because the project fails, This would make the gains made under this system go to waste. However, at that time, China's main goal was to catch up with and surpass the world, and many projects were formulated with a purpose and reference, and such loopholes could not be seen in a short period of time.

When it comes to this time and space, things are simple, no matter what Jiang Tian takes out, it can be regarded as leading the world. However, China's long-term lack of systematic cultivation and self-evolution of scientific knowledge is not something that can be solved by the next decree of the emperor. In a folk study that is limited to some unknown secret recipe, no matter how amazing the level you have achieved, such as the bronze sword of Goujian, the king of Yue, whose surface is treated with chromium-silver oxidation, if that technology can be popularized on a large scale, it will definitely rewrite the history of the development of human metal artifacts, but like many unknown exclusive secret recipes, it can only be used as an isolated case to prove that China's metallurgical level was once 2,000 years ahead of the world......

Jiang Tian and Zhang Tao discussed this problem, if the Academy of Sciences wants to develop benignly, it must have an independent education system, Zhang Tao has not made any attempts, but the level of the Imperial Academy is indeed not flattering, which is also the reason why he promised Jiang Tian to start a new stove, and the other is to transfer the research and development results of the Academy of Sciences to the people for a fee, so that new technologies and new systems can be promoted, businessmen are profit-seeking, they will distinguish between good and bad, and they are willing to accept new things. At the same time, it will let some people who have special technology see that open secrets can also make money, and the state also supports and encourages this kind of scientific research and invention, otherwise how could Zhang Tao agree that Jiang Tian will register the printing technology patent three times and twice, but it is just a sample to show the world. The only thing to be aware of is the pollution and unemployment of large-scale industrialization, but the door of industry has not yet been touched, and this is not something to be considered immediately.

Jiang Tian looked at the manpower stamping machine that was rushed out and announced with regret: "Okay, the development has come to an end, and the New Year is coming soon, and everyone also needs to rest, and strive to be able to deliver good news directly to the front of the emperor when the spring flowers bloom next year." ”
