Although Zhu Ao was a liberal arts student, he was also admitted to university, and he still learned some simple physical and chemical principles in middle school, such as the laws of mechanics and the like, so he personally compiled textbooks and taught them to teachers in vocational and technical schools, so that they could train more qualified craftsmen for themselves. In particular, the subject of geometric arithmetic is the top priority of the vocational and technical college, and arithmetic is the foundation of all disciplines.

The head of the Hu craftsman, who had presided over the construction of the large waterwheel for Zhu Ao, was fortunate to be appointed by Zhu Ao as the general office of the Suguo Arsenal, which was subordinate to the Ministry of Industry, but as usual, a eunuch was sent by the master of ceremonies to supervise it to ensure that the arsenal could serve the Suguo according to Zhu Ao's intentions.

This head craftsman can be said to be very grateful to Zhu Ao, who put them craftsmen in his eyes before, he is often calling and drinking, not only to complete the tasks of the public, but also often sent private work by officials of all sizes to build houses and gardens for them, etc., which is unspeakably miserable.

Now it's okay, the king not only let them start a new stove, become their own family, take care of their own profits and losses, and never have to be exploited by those officials, but also gave him the position of the first general office of the arsenal, although the king did not say that the general office is a few officials, but how big and small is also an official, I didn't expect that when our old Hu can still be an official in this life, he immediately kowtowed to Zhu Ao a few times, knelt on the ground and swore and promised: "Thank you for the king's grace, the villain will definitely run my arsenal in Suguo, Forge a lot of sophisticated weapons for the king to help my king conquer the Quartet! ”

Zhu Ao was happy, this product is really an official's material, the butt is not hot yet, but the kung fu of patting the sycophants is a set, and said with a smile: "Get up, over the years, you have built countless large waterwheels, hand presses and weapons for my Su Guojian, and you have made a lot of contributions, and it is still very relieved to hand over the arsenal to you." However, don't be in a hurry to be happy, the widow still has a few secret tasks to be handed over to you to do, these few things are related to the development of my country, you must do it well, and you are not allowed to leak a word to anyone, otherwise the door will be beheaded! ”

The head of the craftsman was taken aback by the last four words Zhu Ao, and the hairs all over his body became nervous, he really didn't know what kind of great responsibility the king was going to hand over to him, he raised his eyes and looked at Zhu Ao with a hint of fear, and asked cautiously: "Dare to ask the king what is the matter?" The villain will not hesitate to do even if he is smeared with liver and brain. ”

Zhu Ao's face turned cold, and he said very seriously: "You don't need to be stupid, as long as you work hard, you can handle this matter." After saying that, he told Hu Jiangtou about his intention to develop tin mines in the Hami area to make tinplate and then produce cans, as well as some basic knowledge of his own arquebus, hoping that he could get these things out. In addition, Zhu Ao knew that the cannons of later generations were all rear-loaded, and the cannons in the early years of the Ming Dynasty were all front-loaded, and the rate of fire and power of the front-loading guns were not as good as the rear-loading guns, so he also hoped that the head of the Hu craftsman could try to make the rear-loading guns with skilled craftsmen.

Making tinplate is actually a very simple thing, that is, after the tin is melted off, the iron sheet is put into it to plate a layer of tin, and the principle of producing canned food is also very simple, that is, the meat is put into the tinplate, and then put it in boiling water to sterilize it with steam, and then seal the mouth, so as to ensure that the meat in the tinplate does not deteriorate for a long time. These are the methods summed up by later people on the basis of countless experiments, and they are also based on the basic understanding that human beings are caused by bacteria in the decay of food.

The principle of the arquebus is to use a fire rope that can be ignited for a long time to ignite the gunpowder in the gun chamber, and then the projectile in the gun chamber is urged out, and the fire rope is clamped at one end of a rotating shaft, the other end of the rotating shaft is the trigger, and when the trigger is pulled when firing, the rotating shaft will press the burning fire rope into the gun chamber, ignite the gunpowder, and fire the projectile. The production method of the fire rope is also relatively simple, with a few strands of fine flax kneaded into a fuse, boiled in vinegar or soaked in potassium nitrate for a period of time. Potassium nitrate is the main raw material of saltpeter, and it is not difficult to get, although the purity of the Ming Dynasty's technology will not be very high, but it can be used. The arquebus is a revolution in the history of firearms, and it can be said that it is the prototype of the modern rifle. The advent of the arquebus changed the shortcomings of the previous firearm that had to be operated by two people and was difficult to aim, making the firearm much more powerful.

There are special explanations on the websites of these operations in later generations, and Zhu Ao has also read them, although he can't do it himself, but he can tell these basic originals to the craftsmen and let them ponder.

The technology that drives the development of the world is often a little inspiration after unremitting experimentation, and fortunately, Zhu Ao already knows what these inspirations are, so he can tell them to the craftsmen in a grand manner, and let them experiment in this direction, which is really a bit of a bully.

But there is no way to do this, after all, the future enemies Zhu Di and Timur are not fuel-efficient lamps, if you want to defeat them, you have to do your best, you can't care about what you don't win, and the arquebus will come out in Europe in another fifty years, and it is not a great plug-in to get it fifty years in advance, and it is not a great plug-in, and it is not a Gatling, a steam engine. Generally speaking, the arquebus is still an item belonging to this era, and even after the appearance of the arquebus, hot weapons have not completely replaced cold weapons in the next few hundred years. Whether it is the bird gun of the Ming Dynasty or the iron cannon of Japan, they all need the cooperation and cover of cold weapons, so even if Zhu Ao makes an arquebus now, he can only lead the world a little bit in military equipment, and it will definitely not form a crushing advantage.

Although the arquebus has taken a big step forward in power and rate of fire, it still has drawbacks, and the disadvantage is that it is difficult to reload. After each shot, it is necessary to open the gunpowder slot in the back hall of the gun, re-pour the gunpowder, and then load the lead bullet, and re-fire the next shot, the operation is still relatively complicated, so it also affects the rate of fire very much, and the well-trained shooter can only fire three shots in two minutes, if it really starts, the firepower is still not fierce enough.

There was no other solution to this problem, but to mass-produce arquebuses, which were then equipped to the troops to fight the opponent with three shots. In this way, a continuous and dense firepower can be formed.

As for the rear-mounted Franc cannon, so that it was a Hongyi cannon, Zhu Ao didn't know how to get it at all, and hated that he didn't pay attention to this information at the time, and now he has no way to get it, so he can only rely on the wisdom of the craftsmen.

For Zhu Ao's ideas, Hu Jiangtou heard it in a fog, I really don't know how many things we kings have in our heads, and our craftsmen who have worked all our lives have never heard of any canned food or any bird guns. But he was a knowledgeable man, and he already knew that these two things were not trivial just by listening to them. If the canned food is made out, after marching and fighting, there will be no need to worry about military rations. If that bird gun is made, it will be much more powerful than the current fire gun.

No wonder the king is so cautious and doesn't let us divulge a word. Hu Jiangtou immediately knew the seriousness of the matter, and every hair on his body became nervous, kowtowed heavily to Zhu Ao, looked at Zhu Ao with extremely resolute eyes, and said: "Please rest assured, from now on, the ministers will take a group of capable cronies to study the practice of cans and arquebuses, and the ministers will never go home until they are made." "This master carpenter has lost no time in proclaiming himself a minister to Zhu Ao, you must know that it is not easy to be a minister in ancient times, you must first be an official.

Zhu Ao just likes his determination not to break Loulan's oath and never return it, engaging in scientific research is to need this stubbornness and drilling, can not be afraid of failure, Edison invented a light bulb failed more than a thousand times, not to mention making a big killer to hang the opponent, nodded with great satisfaction, and smiled slightly: "Okay." The widows will set up a secret military factory for you in Hami, and you will find tin ore in Hami in the name of digging iron ore, and then secretly develop cans and arquebuses. The tin mine should be in the Mingshan area, you should look for it. ”

Hu Jiangtou raised his head slightly, looked at Zhu Ao suspiciously, and really didn't know how Zhu Ao knew about the tin mines in Mingshan, but he didn't dare to question it, and immediately kowtowed, and said: "The minister remembers, the minister must do his best." ”

Zhu Ao nodded slightly, thought for a while, and said, "You can retreat first, give you a month to prepare, and after the New Year, you will take your people to Hami to develop these two things for the widow." As for the handling of vocational and technical colleges, you can leave it to someone else. ”

"Obey." The head of the craftsman Hu kowtowed heavily to Zhu Ao again, then stood up, and retreated respectfully, and began to think in his heart that his team must be honest and reliable and have very exquisite skills.

After the head of the craftsman Hu left, Zhu Ao began to ponder with a melancholy face, although Lao Zhu abolished the Jinyi Guard, but with his character, he would definitely not be willing to be blind from now on, he would definitely use other ways to monitor every grass and tree in the country. Therefore, the development of canned food and arquebuses must be kept secret, otherwise if Lao Zhu knew that he had made such two big killing weapons, he would definitely use various means to force himself to hand them over, and he would not have the strength to compete with him now.

How can I hide it from Lao Zhu's ears and eyes, Zhu Ao took great pains, and suddenly felt like a leader in the period when the founding of the People's Republic of China had just been founded, and he had worked hard to get atomic bombs and other weapons in order to hide from hostile forces.

The most ruthless emperor's family, the son guards against Lao Tzu, Lao Tzu guards against his son, the nephew guards against his uncle, and the uncle guards against his nephew, which is really nerve-wracking.

The arsenal and vocational and technical school were set up under the vigorous promotion of Zhu Ao, and the school site and the site of the arsenal have also begun to break ground. Military and civilian households are also looking forward to the completion of the factory, so this means that they will have better weapons in the future, and they will also get more credit on the battlefield and pay fewer casualties.

Zhu Ao, the general office of the arsenal, handed over to the head of the Hu craftsman, but temporarily in order to hide his eyes and ears so that he could make arquebuses and cans with peace of mind, he was assigned another errand - to go to Hami to find iron ore to solve the problem of iron shortage in Suguo. For the time being, the affairs of the arsenal will be handled by other people.

And the former principal of the military academy, Zhu Ao, appointed a commander who was good at training recruits to make Chu Yucheng responsible, many people knew that Lao Jiang started by relying on the Whampoa Military Academy, and they were very puzzled why Zhu Ao did not concurrently serve as the principal of the military academy, but gave it to others. You must know that all the officers who came out of this military academy are the future officers of the Su Kingdom, if they all become the children of this person, wouldn't it be a great threat to the royal power?

If Lao Chiang was just the principal of a military academy, he would never be able to squeeze out Wang Jingwei, because Wang Jingwei was the chairman of Guangdong Province at that time, and the Kuomintang at this time occupied the province of Guangdong, which means that Wang Jingwei was actually equivalent to the president of the state. A little principal confronts the president of the country, who do you think the students will stand on? No matter how good the relationship with you is, after all, everyone is going to military school for the future. The principal is only responsible for training students, and his greatest power is nothing more than giving you the title of an outstanding graduate, while the president of the country is responsible for the use of officers, and can determine your official position and future.

In fact, when Lao Chiang fell out with Wang Jingwei, he had already been promoted to the minister of military affairs and the commander of the Guangdong garrison by virtue of his outstanding work ability, especially the commander of the Guangdong garrison, which was even more incredible.

The power to decide the fate of the other party and the deep teacher-student affection prompted the generals from the Whampoa Military Academy to stand on Lao Jiang's side in the battle between Lao Jiang and Wang Jingwei, prompting him to reach the pinnacle of power.

Therefore, there is no need for Zhu Ao to surrender his identity as the principal of any military school, he is the king of Suguo, and the power of life and death of all officers in Suguo is in his hands, and if he wants to inherit his father's position, he must also get Zhu Ao's approval, the document signed by Bing Cao, a principal is only responsible for training, at most he has a little incense with the students, if he dares to rebel, which student will stand on his side if his brain is convulsed?

Therefore, it will not threaten Zhu Hao's royal power at all.

After these two things are settled, the next thing is how to set up a secret military factory to quietly study cans and arquebuses, about this matter, Zhu Ao has no eyebrows, and this matter is too confidential to be taken to the court to discuss, which really makes him hurt his brain.

That night, Zhu stayed in Di Linazha's dormitory. Di Linaza saw that Zhu Ao frowned, and her heart was heavy, and she didn't know what troubles he encountered. She is a very thoughtful person, and she will not ask Zhu Ao about her heart in front of the palace maid and eunuch, because she knows that Zhu Ao is very cautious, and she will not confide in her heart when outsiders are present.

Di Lina ordered someone to prepare a table of delicious side dishes, and after scalding a pot of daughter red, she waved her hand and sent all the palace maids and eunuchs in the house outside. There were only the two of them left in the huge palace, Di Linaza stood up, picked up the wine jug with a pair of plain hands and poured a glass of wine for Zhu Ao, and then gently brought it to him, and said with a smile: "The concubine doesn't know what Your Majesty is worried about, I hope this glass of wine can relieve Your Majesty's little sorrow for the concubine." ”

Zhu Ao smiled knowingly, turned his head to look at this beauty who offered wine with both hands, and secretly said that he was really stupid, he didn't need to guard the beauty of this confidant, what was the use of sighing alone, he took the wine glass with one hand, turned it around in front of his eyes, and then put it to his mouth, raised his head and drank it all, and said: "Aifei, do you remember what you said to persuade the widow to stand on his own?" ”

Di Lina was overjoyed, it seems that the prince listened to what she said, which not only proves her IQ, but also shows that the prince attaches great importance to her, there is nothing in this world that makes her happier than this, Ying Ying smiled and said: "Of course remember, is Your Majesty finally willing to listen to the words of the concubine?" After speaking, he picked up the wine jug again and filled Zhu Ao's empty wine glass with wine.

Zhu Ao raised her head and drank another glass, turned her head to look at the peerless Concubine Duan, and asked with a smile in a tone that tested her: "Then do you remember your method of persuading widows to stand on their own?" ”

Di Linaza used chopsticks to take a bite of food for Zhu Ao, held it to Zhu Ao's mouth with her other hand, and after feeding him to eat, she said with a smile: "Your Majesty, why do you bother to ask your concubines again, presumably Your Majesty has already made a decision in his chest." Although the Ming Dynasty is great, as long as His Majesty subdues the Warat in the north and the Uighurs in the west, then whoever becomes the emperor in the future will not dare to touch you easily. In this way, His Majesty will be able to avoid the fate of the vassal kings who have been cut down in history. ”

"yes." Zhu Ao raised his head and looked ahead, and said thoughtfully: "The widow is now in the land of the four wars, and the country is still very small, the national strength is not sufficient, if you wait to occupy the resources of Warat and the Uighurs, then the widow will become a strong country not much worse than the Ming Dynasty, and the emperor of the Ming Dynasty will not dare to move the widows, otherwise he will face the situation of his own hemorrhage." ”

"Your Majesty is clear, and according to the concubines, with Your Majesty's wisdom and martial arts, it is not difficult to subdue these two countries, as long as Your Majesty is still alive in the past few years, the whole army is strong, and the two powerful countries are conquered, then you can be invincible, and future generations will enjoy thousands of miles of rivers and mountains forever." Di Lina stood up with a smile, walked behind Zhu Ao, put her hands on his shoulders and squeezed them gently, she knew that the pressure on her man was too great, and as his woman, she had the obligation to use all means to make him happy and relaxed. As a woman, there is no way to stand on her own like Wu Zetian, she can only rely on her own man to live, and if the man is good, she will be good.

Zhu Ao patted the plain hand she placed on his shoulder to show his gratitude for her carefulness, and said with a sad face: "The Uighurs in the west are still crippled, but they have been crippled by the widows, and with the encroachment of the Timurid Empire, they will not be able to recover in a short time. When the widows have arranged all the matters related to the construction of the country, and after the military strength is restored, they can send troops to destroy it. However, the Warat in the north is not easy to deal with, not so much how strong they are, but they are all cavalry, living in pursuit of water and grass, fighting if they can fight, and running if they can't fight, it is really difficult to eliminate, and it is difficult to transport grain and grass when marching in the desert, which is the most headache for the widows. ”

Dilinaza is a Mongol, naturally knows the habits of Warat, this Warat is not a descendant of Genghis Khan, but a regime that has a generational intermarriage relationship with the Temujin family, previously under the leadership of the Northern Yuan, after the Northern Yuan was destroyed by Lanyu, began to fly solo, in recent years in the steppe gradually developed and expanded, has gradually become a threat to the Ming Dynasty.

However, since she has married Zhu Ao, she naturally takes her husband as the key link in everything, and does not care about the national righteousness, but still gently massages Zhu Ao, while explaining slowly and logically: "Your Majesty is right, Warat and other northern nomads live in pursuit of water and grass, but this does not mean that they can go anywhere. Because the northern desert is not everywhere the water and grass are abundant, generally speaking, the water and grass in the south of the desert are more abundant, and the north is much worse due to the cold climate. According to the concubines' knowledge, the main force of Warat has always been entrenched near the Zabkhan River, which is about 1,200 miles away from Hami. As soon as His Majesty crossed the Altai Mountains and attacked the lair of Warat, they had to fight or move to a more barren place, and their power was greatly lost. ”

Zhu Ao couldn't help but be overjoyed, raised his head and looked up at his beautiful and resourceful concubine, the queen is good at dealing with all kinds of interpersonal relationships, the concubine is as careful as a hair and will be comfortable to serve the widow, the virtuous concubine is good at settling accounts, and takes care of the various money and grain accounts of the country in an orderly manner, so as not to let the widow worry, but this concubine is good at military strategy, she is simply a female Zhuge , God bless the widow, and send so many virtuous internal helpers to the widow.

On a whim, Zhu Ao ignored Di Linazha's identity as a harem, and talked to her about state affairs, and said with a smile: "What Concubine Ai said is very true, but it is not easy to transport grain for thousands of miles, let alone in the distant desert. What if Warat hides from us, runs away when the army passes, and then returns after we have withdrawn? Aren't we going to make an empty trip and waste a lot of national strength in vain? ”

Di Linaza frowned, this is also the problem she is most worried about, and she has been thinking about this problem during this time, according to her estimates, if you want to go on an expedition to Warat, it will take at least 80,000 to 100,000 troops to achieve your strategic goals, so many troops consume an astronomical amount of food every day, if you lie down and run empty, you don't need Warat to fight back, you can drag yourself to death, I haven't thought about it for a long time and haven't come up with a perfect way, so I can only frown, with a hint of apology to Zhu Ao said: "Return to Your Majesty." When Emperor Wu of the Han Dynasty counterattacked the Xiongnu, he used five people to supply a cavalry, and all the national strength of the prosperous Han Dynasty was hollowed out, and the problem of border troubles in the north was not completely solved. It's just that the concubines are stupid, and they haven't thought of a way to share His Majesty's worries until now, so they are really ashamed. ”
