After all, large-scale processing of rifling is no longer a job that can be carried out in a handicraft workshop, if you want to buy machine tools, you can only go to the Academy of Sciences, and if you want to use special alloy cutter heads, you can only choose the Academy of Sciences, and this time Zhang Tao did not adopt the administrative orders under the wartime economic system, but instead delegated the procurement and upgrading work to the arsenal, The army only announced plans to upgrade its weapons and equipment, and as for which arsenal will get the largest share of production, this is their own competition, in other words, it is like the arms purchase in later generations, and the government only has to watch these arms dealers bid. It is precisely this new form of procurement that has made the Academy of Sciences the biggest winner in this change, whether it is the Central Arsenal in Beijing or the Jinling Arsenal in Nanjing, officials in these places revolve around the old man Song almost every day, just to be the first to get a full set of rifling processing equipment, so as to gain the initiative in the next bidding, but they soon found that the design patent of the Mini bullet has been registered by the Academy of Sciences, as the Academy of Sciences with a full set of intellectual property rights is not just charging equipment procurement fees, If you want to make qualified guns and ammunition, you have to spend more money later.

"In this way, the scientific research system can enter a virtuous circle of development, and it will not be long before these large manufacturers will inevitably develop new technologies on their own in order to reduce production costs, and the Academy of Sciences will be able to get rid of the current state of managing everything in a huge and meticulous way, as long as it focuses on basic science and frontier fields." At the last regular meeting of the firearms research team, Jiang Tian said his and Zhang Tao's plan: "Let science develop naturally in a commercial environment, although it is not as fast as our high-flying concentrated research, but it can drive the benign development of the entire industry and scientific research field, and in the future, you will also participate in the follow-up research and development as the backbone of the professional field, so I need everyone to bring the systematic and standardized research model I learned from me to other projects, so that we can ...... in interdisciplinary and cross-field research and development."

Jiang Tian's report has a sense of summarizing the work of later generations, if you change to a modern person sitting below, you will definitely yawn, but these elites who have been gathered by the Academy of Sciences will never dare to be so presumptuous, this is not only Jiang Tian's official rank, the background is hard, but also because of the rifle development work of Tong Guò this time, many people suddenly found that their original scientific knowledge worthy of boasting was useless in such a simple research and development work, Jiang Tian proposed a gun type scheme like a book from heaven to make people scratch their heads, Moreover, the research and development of a single bullet spanned the fields of metal precision machining, aerodynamics, chemical preparation, and dangerous goods storage management, and then the hand-built bullet began to be tested and finalized for a long time. Just after everyone thought that the work was over, the research and development of equipment for industrial production and the development of regulations for the management of ammunition storage and transportation began. Just a small paper-shell fixed-loading bomb makes these former elites unable to find the north, let alone the copper-shelled bullet. Without Jiang Tian's participation, the research and development work does not know how many years it will take, and even if they finally succeed, they may not be able to surpass the current technical level.

The scene changed, and Jiang Tian was sitting opposite Old Man Song and drinking tea at this time: "The main work of the Academy of Sciences next is to catch up with the advanced machining level in the field of chemistry!" With this research and development work, our metal smelting and manufacturing capacity does not need to be changed for the time being, and all that remains is to train a large number of qualified skilled workers for the arsenal. However, the development of the fire cap made me feel extremely depressed about our chemical production capacity, that is, the production of this half-hung red phosphorus fire @ cap has to take so much effort, if it is replaced by the original plan of thunder @ mercury @ fire @ cap, our sulfuric acid preparation capacity is completely incompetent for the needs of large-scale production. ”

Old man Song, who had made up a lot of chemical knowledge, nodded: "I also understand what you said, but the preparation of these three acids and two bases in the real room is not stable enough, how can such a dangerous thing be produced in large quantities?" ”

Jiang Tian also understands that this is the consequence of the lack of overall industrial strength, and can only gradually get rid of this embarrassing situation by carrying out industrial upgrading little by little: "Alas...... After the Beijing camp is finished, I think His Majesty will definitely find an opportunity to go on the Northern Expedition immediately, otherwise the acquisition of this trona will be restricted by others! ”

Jiang Tian's estimate is good, even if there is no Manchu remnants active in the grassland, even if it is to obtain a stable supply of raw materials, Zhang Tao has a reason to launch a large-scale war, which is the same as the Han Dynasty in order to obtain good horses and destroy the Dawan Kingdom, although now you can still rely on tea, salt, iron and grain trade, in exchange for urgently needed raw materials, but everyone knows that for long-term peace and stability, directly grasp the origin of these resources is the safest way. And Zhang Tao does this is what he conceived, and at the same time he has another layer of consideration, a country's army can not gradually wear off its sharpness in peace, they need blood and military exploits to maintain a strong fighting spirit, then the easiest thing to start around China is the Mongolian steppe, there is a suitable reason to fight here, and there are also enough interests to drive, I want the Han Dynasty to expel the Xiongnu with iron hooves, the Tang Dynasty used the method of division and disintegration to destroy the Turks, and the Ming Dynasty simply guarded the Great Wall as a shrinking turtle, None of these methods can completely solve the troubles that have plagued China for thousands of years, and in Zhang Tao and Jiang Tian's view, the best way to get these endless nomads to completely remove the threat to the Central Plains is to put them under their own territory, implement a policy of complete assimilation and disintegration, and make them emotionally identify with the fact that they are Chinese, and then there will be no more......

After the research and development work was over, Jiang Tian returned to his life of teaching and educating people, but now the number of senior classes that require him to attend classes in person is gradually decreasing, and the original students are either poached by the Academy of Sciences, or they are just messing around and can no longer keep up with the progress of learning, and those international students sent by Japan are still floating on the sea. Therefore, Jiang Tian's life as a teacher is much easier than before, but what he didn't expect was that Liu Baokai, who didn't learn and didn't know how to do it, could actually complete the promotion exam.

"Yijian, you're not going to cheat again, are you?" Jiang Tian looked at the barely passing exam papers, and sincerely did not believe that Liu Baokai had the ability to answer the questions by himself.

The pervert @ wolf was not happy when he heard it, but he didn't dare to directly confront Jiang Tian, so he had to squeeze out a little smile and said: "Look at what Mr. said, no matter how stupid I am, I have been ignited by your Wenqu star, and this time I saw you and Dexin make a musket together, and when I looked at it, I felt that there were many things in it that were similar to the knowledge in the book, and what I couldn't understand before was also a little clear." ”

Song Yi knew that his friend was indeed not cheating, so he hurriedly helped to say good things: "Yi Jian is right, I used to read Mr.'s textbooks, there are many obscure and difficult to understand, even if I can be ordered by your ear, it is nothing more than swallowing dates and not knowing why, but this time I saw you make a gun, I suddenly felt that a small rifle is so complicated, and those unclear places are compared with the content in the textbook, and I understand Mr.'s good intentions when compiling the textbook." ”

This sycophant is said to be numb enough, Jiang Tian listened to it but didn't feel anything, you must know that the rifle is not a high-tech weapon in the later generations, and anyone with middle school knowledge can explain how it works. But how many middle school students find the knowledge they have learned useful? For example, Jiang Tian himself felt that learning geometry and algebra was a complete waste of time. However, even higher mathematics, which he saw as completely useless, played a decisive role in this research and development, because there were some calculations that no one could help except himself.

As a representative of outstanding students, Zhang Huan no longer doubts the role of mathematics, but he still finds learning mathematics not as interesting as other subjects: "Sir, if a person like me who can't learn mathematics well, it would be great if he could stop getting entangled in those formulas and diagrams!" ”

Zhang Huan was originally just a sigh, but it reminded Jiang Tian of a key problem, this time he just made a small rifle, and he almost vomited blood, if he built a cannon or something else in the future, he would be able to use it alone, the key is that the students in these advanced classes are not available in a short time, this is not counting Liu Baokai, Zhang Huan and other gentlemen are unlikely to give up their family business to become scientists, so the popularization of computers is a top priority. Of course, this kind of computer is not a computer, but a hand-cranked computer that has appeared in history, or various simplified versions of the slide rule.

Just when Jiang Tian and the students were exchanging scientific insights, there was a group of people who were obviously not as relaxed as him, and the envoys from all walks of life who were invited to visit the military parade, except for some soy sauce countries, were the most nervous in the Netherlands, Japan, and North Korea. As soon as he heard that he could watch the parade, the Dutch East India Company sent a clerk of sufficient weight to serve as a temporary ambassador, and this man had fought in Europe and was familiar with the situation of the army, and he studied it with the missionaries. Not to mention anything else, just the quantity and quality of firearms are beyond the reach of European countries, the Beijing camp and the forbidden army have a total of more than 100,000 people, even if these troops are the main force of the main force, the penetration rate of firearms has reached an astonishing 70 percent, this is still because the baggage and artillery have lowered the percentage, and the army on the front line is a pure firearms force! In Europe, even the Dutch, who have a rich waist and a small population, do not dare to play like this, and the envoy is also keenly aware that most of the firearms used by these troops participating in the parade have a certain degree of wear and tear, which shows that the muskets they carry are not fakes used to fill the appearance, and they have trained more times in peacetime, and in the face of such a well-equipped and well-trained standing army, the strength of the Europeans in East Asia alone is not enough to stuff people's teeth, but fortunately, the navy of this country has not developed. As long as you don't go to the land to provoke him, it's not a big deal.

The Japanese are also thinking about this, Heizo as a businessman naturally can't understand complex things, but he can understand that the spirit of these soldiers is completely different from the ashigaru under the Japanese daimyo, not only is he tall and strong, but even the long musket is much stronger than the bird gun or Tanegashima iron cannon he has seen before, not to mention that those tall horses can overwhelm these dwarfs in terms of momentum. However, he was not worried about Japan, for a long time the sea protected Japan from being annexed by the dynasty in the Central Plains, and China would not be interested in barren Japan in the future, and besides, he was now focused on staying in China and settling down, if it were not for the difficulty of naturalization, he should now cheer for his "motherland" to be so strong.

As for the already preoccupied North Korean envoy Kim Yong-tae, after the military parade, he immediately sent a letter back to China, which described in detail what he had seen and heard about the Central Plains army, he was not a military expert, and his vision of firearms was not even as good as that of Pingsan, but he knew that the combat capability of this army was beyond doubt, especially recently I heard that the powerful musket was about to be eliminated, and the Central Plains seemed to have more powerful firearms, and it was not surprising that this new weapon was also from Jiang Tian's hands, Although it is impossible to inquire about the power of this new musket, judging from the excitement of many Central Plains officials discussing the Northern Expedition, it is estimated that it is of decisive significance. As for how to keep Jeju Island, he also analyzed the pros and cons in detail in the letter, and compared with offending the Central Plains, sometimes the only way to let go is to let go...... His letter caused an uproar in Korea, and those ministers who had secret industries on the island were naturally strongly opposed, but the big guys understood that they could not stop the Central Plains army, not to mention that after hearing that the money for the purchase of the island was directly allocated to the Joseon royal family, those ministers who had no interests in Jeju Island and the forces that firmly supported the royal family had the upper hand, and all those who opposed the sale of the island were labeled as disloyal and unsubordinate, so no one dared to speak out against it. Next, the king of North Korea authorized Kim Yong-tae to be directly responsible for the negotiations, and the content of the negotiations also changed from how to protect the territory to how to make a little more money.

As for this negotiation, Jiang Tian does not need to participate, if he can't even do this thing, those officials of the Ministry of Foreign Affairs will be able to remove him from his post and investigate it. But no matter what the other party says, he is also a special envoy of a country, even if he is your little brother, he must have basic etiquette. Therefore, as the foreign minister, Hu Jingyi "reluctantly" made the next move that will go down in history, and finally signed the "China-North Korea Jeju Island Lend-Lease Agreement". The agreement stipulates that China will lease Jeju Island for 99 years at a rent of 100,000 won per year, that China will be responsible for the civil affairs and national defense of the island, that the former DPRK nationals can choose their nationality again, that the original land owners on the island can enjoy a policy of redemption at a high price on the basis of the land deed, and that after the lease expires, China will automatically own sovereignty over the island and its affiliated waters. At the same time, the treaty also came with additional provisions, first of all, the Central Plains Dynasty helped to build a new army loyal to the Joseon king, the military equipment was provided free of charge by China, and Koreans were allowed to study in the Central Plains, and the most important thing was that Jiang Tian's private school must exempt Korean aristocratic students from entrance examinations.

This lease is regarded by international historians as the first unequal treaty directed by Jiang Tian, which is different from the love and willingness with Japan, everyone knows that it was the military parade that scared off the small abacus of the Korean monarchs, but legally speaking, it is impeccable, and the Joseon Dynasty, which seems to have taken a big advantage, found itself too stupid in a few years, 100,000 silver dollars a year seems to be a lot, in fact, it is not worth mentioning on an island of this size of Jeju Island, and according to the later development situation, not only has it become a supply base for the Chinese Navy, The island's agriculture and animal husbandry have also become the logistical pillars of the Chinese army, and the annual output value of the silver dollar has exceeded 100,000, let alone twenty or thirty years, the purchasing power of the silver dollar began to decline. Not to mention that after the loss of Jeju Island, and then in the subsequent division of the sea frontier, North Korea suffered a loss until it vomited blood. It was not until 200 years later, under the tide of historical reversal, that some Koreans put forward another interpretation of this treaty, that is, Jeju Island was exchanged for a ticket to enter the world's first-class scientific and technological universities, which played an immeasurable role in the development of North Korea's science and technology. It's just that the current North Koreans don't know this, their biggest headache at the moment is which nationality to join, in addition to those sinners who are in charge of the army, the island is mainly some local fishermen and craftsmen, here because of the development of animal husbandry, so it was once the main production area and raw material base for the manufacture of bows and arrows, and their main customers are also those ethnic minorities in the northeast, but since the new army in the Central Plains played the musket superbly, the sales of bows and arrows have been sluggish, and North Korea's export industry has also shrunk sharply, Now that the Chinese are coming, they will certainly not be able to use the primitive weapon of bows and arrows, so those craftsmen will have no use, some of these people want to return to the peninsula for development with their craftsmanship, and some people dream of becoming the subjects of the Heavenly Dynasty, so for a period of time all kinds of controversies caused by just going to stay are full of streets and alleys, and the only ones who are indifferent to this are those exiled prisoners and their families, for whom they are inferior no matter where they stay, Maybe the new master is better at talking than the original officials. As for whether slavery can be abolished after becoming Chinese, these people don't even dare to think about it.

Correspondingly, a similar problem arose in Jiang Tian's family, as this guy's official position increased, and at the same time, his fame in the court and among the people became bigger and bigger, and the people who stayed in the house became more and more consciously regarded themselves as servants and slaves, and no one felt that they were free, or they took the initiative to give up their identity as civilians, and returned to their original tracks.

"How many times have I said that I will be paid for your work, but I have no right to decide whether you live or die!"

There is a team of musicians in Jiang's mansion, and not all the little girls are dreaming of becoming the woman who gives him Lord Jiang, so a girl who is just in love hooks up with the little girl in the mansion and becomes an adulterer, plus Jiang Tian has never had time to ask about the management of the mansion, so finally one day, this girl's endless pregnancy reaction attracted the attention of others, which can be regarded as a hornet's nest.
