The production of artillery can not be achieved overnight, it requires continuous trial production and test firing to sum up the most reasonable production process, which Zhu Cijiong has no choice, after all, the production he participated in in the production of modern artillery in his previous life, and the material, structure and processing methods are not the same thing as ancient artillery at all. He could only explain the casting method and experimental method of the artillery to Xu Guangqi and Bi Maokang in detail, let them go to trial production, let them test fire, of course, the final finalization still had to be checked by himself.

The trial production of artillery has not yet come to fruition, but the "Treaty of Friendship and Mutual Assistance between the Ming Empire and the Portuguese Empire" has borne its first fruits. It turned out that Shi Weila did not return to Macao immediately after leaving Beijing, but stayed in Jinling for a few days, and went to visit Zheng Zhilong, the king of Zhennan.

Zheng Zhilong was originally a pirate, and he was the largest maritime merchant on the southeast coast, and when he first started doing business, he was doing business with the Portuguese, and the two naturally had a lot of common language. In particular, Zheng Zhilong also worked as a Portuguese translator, and the Portuguese is even more slippery than Shi Weila, and the chat with Shi Wei is called a pleasant one.

chatting and chatting about Schvila talked about the treaty, and now Zheng Zhilong couldn't sit still, the Western trading company is equivalent to him in charge, and now the business is not good. The Spanish merchants and the Portuguese merchants were afraid of the pirates instigated by the Dutch, and they did not dare to come here to buy goods, and the Dutch merchants did not want to deal with them, and there were no big customers in those trading points in Nanyang, and he could not sell the things produced by the four big factories of Jiangnan Weaving, Jiangnan Porcelain, Jiangnan Tea Industry, and Tianjin Weaving.

The output of the four large factories has decreased and decreased, and there is a lot of backlog of goods in Jinling City, and now Portugal has become an agent of the Ming Dynasty, so don't hurry up and sell it!

The backlog in Jinling City is some high-end porcelain, high-grade tea and silk, which ordinary people really can't afford, so they can't be sold. Unexpectedly, as soon as Svera heard about these things, the green light in his eyes came out, good things!

In Europe, bowls and plates are also used for eating, there is no melamine plastic at that time, no money is used wood, rich is used metal, the appearance is ugly, not to mention, it is not easy to clean, so porcelain is quite in demand in Europe, especially in aristocratic families, there are not a few cabinets of porcelain bowls and porcelain plates at home, you are embarrassed to say that you are a nobleman?

Tea is also, Europe and the United States are now popular to drink afternoon tea, at that time the commoners can not afford to drink, but the nobles have to drink, milk tea can not afford to drink you are embarrassed to say that you are a nobleman?

Not to mention silk, at that time the ball was popular in Europe, and the dress became an important prop for the comparison between the nobles, especially the lady's dress, you don't need silk to do it, you are embarrassed to say that you are a nobleman?

How much of a shunt are fine porcelain, fine tea, and silk in Europe? Let's put it this way, there are no sales at all in ordinary places, only in big cities, and most of them are auctions!

As soon as this thing is shipped to Europe, it is more than ten times the profit, Schvera opened his mouth and swept away all the backlog of goods, but in the last time he talked about money, he ......, not to hurt his feelings, but Schvera couldn't make up so much money for a while.

The market price of these things is about 10 million taels, but according to the treaty, it is more than 30 million taels, and he can only scrape together about 15 million taels in a short time, and most of them have to rely on his boss Kong Dede to make up. I want this batch of goods, but I can't get together so much money, and Schvera's tangled appearance is really pitiful.

Unexpectedly, Zheng Zhilong sold all the goods to him very generously, and promised to help him send them to the territory of the Indian Governor Conde, and the money could be paid fifteen million taels first, and the rest would be paid when the things were sold.

Schwila is naturally grateful, this time and again, excluding costs and various expenses, he can earn at least 30 million taels this time, what kind of concept is this, you must know that the accumulation of more than 200 years of his Quir Niño family does not add up to 30 million taels! Moreover, they also helped him deliver goods to India for free, which reduced the danger of transportation by more than half. Anthony (Zheng Zhilong's Catholic name), what a good man!

Is Zheng Zhilong a good person? Of course not, he's a big pirate, and he's afraid he won't get the rest of the money back? It's a big deal to give him Macau, tie up all the Portuguese, and let people use money to ransom them, this is called kidnapping, he used to do it often, and it's not bad to have a chance to review it.

That's it, Schvera hasn't brought the treaty back, Daming got the first benefit, fifteen million taels is not too much, but this is just the beginning, Schvera said when he left, let your factories work at full capacity, I want to do as many of these things as I want!

Jiangnan Weaving, Jiangnan Porcelain, Jiangnan Tea Industry, and Tianjin Weaving These four big factories must really work at full speed, and can produce at least five million taels of high-end goods a month, which is fifteen million taels at the price of the treaty, and the total cost of materials and labor is less than one million taels, that is to say, Zhu Cijiong has more than 10 million taels of income a month!

What do you do with more than 10 million taels, it is naturally recruitment, the military expenditure of a 100,000 army is less than 300,000 taels a month, of course, it is the use of cold weapons, if it is fully equipped with hot weapons, it is about 600,000 taels, a million army is only 6 million taels, and 2 million troops are only 12 million taels!

Zhu Cijiong told Shi Weila at that time that he wanted to recruit all the 2.7 million troops back, but he was just bragging, and even he didn't believe it, but he didn't expect it to become real and feasible in less than a month!

If you have money, then expand your recruitment, although the first transaction has not even been completed on Svera's side, but it is no problem to recruit more than 100,000 first, then expand the Beijing camp first, recruit 150,000 recruits, and make up 200,000 first!

Zhu Cijiong is not worried about the spending power of the European aristocracy at all, now is the peak of the Great Voyage, all the European powers are outbursts, there is a lot of money, fever! During this period, high-end porcelain and high-grade tea were fried by them, which was almost equivalent to gold, and silk and spices were even more valuable than gold. At this time, the European aristocracy is really rich, and if you don't make money, you won't make it for nothing!

A few days after the recruitment began, there was good news:

The 5-inch mortar cannon was successfully developed, with a barrel caliber of 5 inches, a barrel length of 2 feet 5, a firing range of 200 to 300 paces, and a combined weight of more than 600 pounds of the barrel and gun wagon, which could be pulled and run by four horses.

Zhu Cijiong ordered: first make 20 sets, each set with 10 artillerymen, and send them to help Lu Xiangsheng and Sun Chuanting defeat Linfen City in Pingyang Mansion after the drill is mature.

A few days later, another piece of good news came:

The 3-inch howitzer has been successfully developed, with a barrel caliber of 3 inches, a barrel length of 5 feet, a firing range of 300 to 400 paces, and a combined weight of 600 pounds of the barrel and gun wagon, which can be pulled by four horses.

Zhu Cijiong ordered: Make ten sets first, and use them for Beijing camp exercises.

A few days later, another piece of good news came:

The 4-inch howitzer has been successfully developed, with a barrel caliber of 4 inches, a barrel length of 7 feet, a firing range of 400 to 500 paces, and a combined weight of more than 1,000 catties for the barrel and gun wagon.

Zhu Cijiong ordered: Make ten sets first, and use them for Beijing camp exercises.

The recruits are almost finished, and there is another good news:

The 5-inch howitzer was successfully developed, with a barrel caliber of 5 inches, a barrel length of 9 feet, a firing range of 500 to 600 paces, and a combined weight of 1,700 pounds for the barrel and gun carriage, which could be pulled by 16 horses.

Zhu Cijiong ordered: Make ten sets first, and use them for Beijing camp exercises.

Wait, why does this cannon sound so awkward, how did it call it in the previous life? Zhu Cijiong recalled it, and immediately remembered that the guns in the previous life all had models, such as AK47, May Fourth style, M311, etc., it was much more convenient to call them like that.

As a result, Zhu Cijiong formulated a simple model naming method:

Like the new flintlock pistol, the caliber is 2 points, and the barrel length is 4 feet, so it is called a 24-type flintlock pistol;

Like a 5-inch mortar gun, the caliber is 5 inches, and the ratio of caliber to length is 1:5, then it is called a 55-type mortar gun;

Like a 3-inch howitzer, the caliber is 3 inches, and the ratio of caliber to length is 1:17, then it is called a 317 howitzer;

The artillery has been developed here, even if it comes to an end, it's not that the howitzer can't be made no matter how big it is, the main thing is that the output of iron ore can't keep up, how much steel was used for a gun before, and now the cannon is hundreds of thousands of catties at every turn, and it's normal to use tens of thousands of catties a day, and now where can the output of iron ore keep up!

It seems that he is going to find Portugal to buy iron ore, not that there is no iron ore in the Ming Dynasty, there is a word called strategic reserves, iron ore is a scarce material in the era of maritime hegemony, and now it is just to make artillery, and when the ironclad battleship comes out, that guy, a battleship is tens of thousands of catties or even hundreds of thousands of catties of steel, who will think that there is more iron ore!

The artillery came to an end, and Xu Guangqi came to report the good news again.

He was originally an astronomy enthusiast, and once combined the Western star catalog with the traditional Chinese star catalog to draw the first all-day star map. This sparked his interest in observing celestial bodies, and he had long wanted to build an astronomical telescope himself, but Daming had no glass industry, so he had to give up.

Now that the glass factory has been built, he is naturally excited, and he even opened his mouth for the first time to apply for funds from Zhu Cijiong to make an astronomical telescope. As a result, Zhu Cijiong poured a basin of cold water on him: What Da Ming needs at this time is a military telescope instead of an astronomical telescope, okay, hurry up and study the military telescope for me!

Xu Guangqi did not reject the study of military telescopes, and soon he made a large-aperture triple-focal length military telescope according to Zhu Cijiong's request.

Zhu Cijiong asked him to make this kind of telescope mainly to measure the shooting yuan of artillery, and the artillery is not a flintlock gun, and it can be aimed at three points and one line. The positioning of the artillery should consider the ruler, height, direction, etc., especially the mortar and howitzer, the trajectory is an arc, if you do not consider the shooting element, you will not be able to hit the target at all.

Hit the cavalry with artillery, if the first shot misses, it is estimated that there will be no chance to fire the second shot. Now the firing range of the artillery is only two miles at most, and the speed of the cavalry is only three or four minutes for two miles.

With a military telescope, it is different, a military telescope with a triple focal length can accurately calculate the shooting elements of about one mile, and the error will not exceed one meter, and the military telescope with a six-fold focal length can accurately calculate the shooting elements of about one mile, and the error will not exceed two meters.

Zhu Cijiong carefully observed the objects about a mile with a telescope, and was very satisfied with this triple-length military telescope, and he couldn't help but praise Xu Guangqi a lot, and asked him to hurry up and make a batch of military telescopes with triple and six-fold focal lengths to cooperate with the artillery drill.

Now, the economy and military of the Ming Dynasty are thriving, and the national strength is getting stronger and stronger, Zhu Cijiong is thinking, maybe it's time to talk to Sun Chengzong about the problem of Liaodong.
