In addition to mirrors, cotton cloth, private salt, and marine trade are all developments, especially marine trade. Japan's saltpeter has a very high sulfur, and there is also a lot of copper.

At present, the technology of steelmaking in the open furnace has not been developed. Don’t think about steel cannons. They can easily break if they have too high phosphorus content. Therefore, only cast iron and copper cannons can be made. Cast iron can also be easily broken, while bronze cannons are easily deformed. But in general, cannons cast in bronze can be better.

China is a place where copper is lacking. The copper coins in the late Ming Dynasty were already seriously insufficient. Not only was there a lack of copper, but many people also used copper coins to melt them into copperware because there was profit.

Because Japan was blocked by the Ming court for a long time, its products were not abundant and its industrial capacity was relatively low, many things were short of, which caused the crazy profits of trade in Japan.

This is also the reason why the Dutch and Zheng Zhilong competed for this fat piece. Zhao Yan also salivated at this fat piece, but there was no ship, let alone a navy.

Private salt has to be discussed, but this cotton cloth is easier.

Zhao Yan immediately summoned craftsmen and began to build mule machines and hydrolooms. As for the Jenny machine, the yarns spun out are fine but easy to break. Although the yarns spun out by the hydraulic spinning machine are strong, they are not fine enough.

The mule machine absorbs the advantages of these two spinning machines. When they are combined, the spinned yarn is delicate and strong. Therefore, it is called mule machine, which means hybridization.

The mule machine can push 300 to 400 spindles, and its speed is more than a hundred times higher than that of an ordinary spinning machine.

Hydraulic looms can increase the speed by 5 times.

Zhao Yan's craftsmen have established a team that specializes in creating these strange things. They can understand Zhao Yan's drawings and the data on it, which makes Zhao Yan much less worried.

It is estimated that it will take more than a month to build a hydraulic mule machine.

"If you encounter a problem you don't understand, send someone to find me, and I'll leave it to you here." Zhao Yan said to Zhou Tieming and the others.

"Yes, sir." Zhou Tieming and the others answered quickly, then looked at the details of the drawings. Generally speaking, this hydraulic mule machine uses hydraulic power to drive the spindles, and the structure of the machine is not too complicated.

Shandong is relatively cold, and the water vapor in the air is not as high as in the south, so if you want to vigorously develop the textile industry, you have to spray some water in the air to increase the water vapor, otherwise the yarn will be easily broken.

...

Zhao Yan successfully helped him, and there was no limit on external development, so the expansion of the village was already necessary. Zhao Yan took out the map and circled the plains from Huangxian to Laizhou.

This plain area can be reclaimed about 3 million mu of arable land, and this plain is the area that has been most ravaged by Kong Youde.

There is no danger to guard the plain. The main area where Kong Youde rebelled was Dengzhou City - Laizhou City. This plain is between Dengzhou City and Laizhou City, and has almost reached the point where nine out of ten rooms are empty.

There is a large amount of unowned land here, and the land is relatively fertile. As long as an effective water conservancy system is established, it can become a large granary.

According to the calculation of a young and strong man divided into 30 acres of land, this area can accommodate 100,000 young and strong man, plus women, children, and elderly people, it can accommodate 500,000 and 600,000 refugees.

"Before the spring of next year, we will need at least 100,000 households to fully resume production in this fast area. Zhonglin, you will take people to inspect tomorrow, and then take people to calculate how much grain, seeds, oxen, ploughing tools, and water conservancy repairs are needed, and how much silver is expected to be spent." Zhao Yan said to Tang Zhengze.

One hundred thousand households! Tang Zhengze couldn't help but be shocked. It took him a long time to react and quickly replied: "Yes, sir."

Then Zhao Yan asked Zhao Quan and asked: "How fast is the current extravagance of the business?"

"Now, there are Jimin Commercial Banks in Shandong provinces and counties. There are three stores in northern Zhili and five stores in Jiangnan, all in the prosperous city of Zhou." Zhao Quan said that during this period, many shopkeepers and literati were recruited. Most of the literati have undergone some simple training and then taken by experienced shopkeepers.

The management of a business is very important, and the most important thing is the issue of corruption. Just like a country, a company also has corruption and poaching the boss's back.

Jimin Commercial Bank does not use the currently popular "longmen account", but uses a duplex accounting method. The advantage of duplex accounting lies in the fact that you can understand the whole story in detail. Any problem in any link can be found quickly.

And based on the experience of later generations, many systems to strengthen management have been determined. Of course, corruption is possible in any company, and it is impossible to completely eliminate it. However, with strict management, even if it is corruption, it can only covertly write in procurement.

Zhao Yan touched his chin and thought for a while, then asked, "How much money do we have now?"

"There are already 1.32 million taels, but the mirrors on the hands of major merchants in Shandong have not yet been completely taken. It will take a month or two to make a large amount of money to be earned." Zhao Quan expected.

“Where is the food?”

"Eighteen thousand stones."

After Zhao Yan learned about his family, he immediately said: "Recruiting refugees in Shandong, and sending people to Northern Zhili, Henan and other places. In addition, before the autumn harvest, the shops were placed in the main cotton-producing areas and grain-producing areas in the south. We definitely have not enough grain. When the autumn harvest is over, we can buy enough grain when the grain price drops sharply. In addition, we have to purchase a large amount of cotton." Zhao Yan said.

"What are we buying cotton?" Zhao Quan asked strangely.

"I just asked the craftsmen to build a spinning machine and a weaving machine, both of which are made of water! This kind of spinning machine is faster than hundreds of people, and the loom is five times faster than ordinary weavers." Zhao Yan explained.

"Hundreds of times! Five times!" Zhao Quan took a breath, rubbed his hands and said happily: "Will we have another source of wealth?"

"Natural." Zhao Yan smiled.

Zhao Quan had no doubts at all, because Zhao Yan said that spinning machines and looms were made of hydraulic power. Gongzi was very good at hydraulic applications.

Zhao Quan often wondered why the young master suddenly knew so many things. However, Zhao Yan never explained, and he never asked. Both of them maintained a very high understanding.

The military farming boom last year has faded, and this year's military farming plan is about to begin.

That... the urge for updates is 12,000 yuan, but Xiaocai really doesn't have that speed! Everyone doesn't have to make things difficult for me.

I have been sitting until now since I woke up today, and I even ate it all in sloppy food, and I have only made these...
