Wang Defa's family is a science and engineering man, and he returned to his house with a question mark in his head.

In fact, after a sleep, he will completely forget all those theories and truths.

The current situation is still good, and it will be good if the battle can be fought like this.

At the moment, the strength of the Tatar bandit group is quite large, and they are only tens of thousands of horses in the guard?

Just hold them back!

The two of them optimistically estimated that in another five years, the Tatar bandits would be dragged to death, but the strength of Liuqiu Island would take a leap!

The next five years are a key, so they need a stable Great Song Dynasty too much, and they can't blame Wang Defa's family for worrying that the Great Song Dynasty will have civil strife.

Wang Defa's family mainly managed the industrial development of Liuqiu Island, and of course, their so-called industry cannot be judged by the standards of later generations.

In the smelting industry, although Liuqiu Island has coke from the Shandong and Huainan regions, and they have long organized captives from all walks of life to mine iron ore from major rivers------ which can contain almost 70% iron, and can be used almost directly to make steel.

However, due to the production volume, they also had to import pig iron from Da Song.

They have the largest steel mill in this time and space, but the total output is still less than one-third of that of the Great Song Dynasty.

In the smelting of non-ferrous metals, in addition to the copper output is far less than that of the Great Song Dynasty, silver and gold have almost reached the level of the Great Song Dynasty.

This is how the rumor that there is a silver mountain and a gold mountain on Liuqiu Island came about.

The reason why the banknotes issued by Liuqiu Island can be used in the territory of the Great Song Dynasty, and the money stores of Liuqiu can also be opened in major cities, are all related to the fact that Liuqiu tickets can be directly bought in Liuqiu, and can even be directly exchanged for gold and silver.

In fact, the silver of the island comes from Japan; The gold came from Zhaoyuan in Shandong and the northwest of the island------ and the owners of Zhang Island had no idea of storing precious metals at all, as long as they could exchange them for the raw materials needed for the development of Liuqiu Island, they did not care about the arbitrary circulation of precious metals, which indirectly supported the issuance of their banknotes.

Gold and silver are never real wealth, the real wealth is all kinds of industrial raw materials and labor!

The sea salt production of Liuqiu Island was completely defeated by the Great Song Dynasty, and it was far behind------ the salt drying technology was too simple, as long as there was cement, the Great Song Dynasty only needed to learn from it.

They will also find a place to go to Hainan Island to build a salt factory.

There is only one refined salt, and the Great Song Dynasty can't learn it for a while, and their department in charge of the salt industry is embarrassed to ask for the secret recipe------ and the owner of Zhang Island prevaricates it in a few words, anyway, the Great Song Dynasty government has not yet developed to the era of robbing other people's industries.

Liuqiu Island began to officially import cement from the Great Song Dynasty------ originally the Great Song City Bosi still wanted to get a monopoly or something, but this industry was too simple, Zhang Island really did not spread the technology to the Great Song Dynasty, and some big households among the people began to do it themselves.

In just one Fujian area, hundreds of large and small cement factories have been launched in a few years!

They will also use black powder to blow up the mountain------ Zhang Island Lord once thought hatefully, if they didn't follow the example, how much more labor could the entire Liuqiu Island summon!

With the reduction of cement prices, the private demand for cement is also huge------ Zhang Island owner has to pinch his nose to buy the cement produced by the Great Song Dynasty, and the label is almost there.

In fact, these are not nothing------ the most hateful thing is that some folk workshops in the Great Song Dynasty also learned their iron-wood structure of water-powered spinning machines and looms!

They had stolen Jenny's spinning machine and hosiery loom early on, which were nothing, after all, they were extremely simple equipment, and they could almost be seen at a glance.

Hydrospinning machines and looms are much more complicated------- they are definitely industrial spies!

Zhang Island Master once viciously said to Wang Defa's family: "There was no incident where they had a textile worker smashing a water-powered spinning machine?!" ”

There is a reason for this, and that was in the mid-18th century, when British goods were increasingly being sold overseas, and the production technology of the artisanal workshops was insufficient.

In the cotton textile sector, someone invented a weaving tool called the shuttle, which greatly accelerated the speed of weaving and also stimulated the demand for cotton yarn.

By the 60s of the 18th century, the weaver James? Hargreaves invented the "Jenny Machine" hand spinning machine.

This "Jenny machine" could spin many cotton threads at a time, which greatly increased productivity, but caused the anger of other spinning mill workers, who thought that the equipment was robbing them of their jobs, so someone took the lead in smashing it.

Wang Defa's family smiled at the time and said: "Where is the demand for cotton cloth in that era as high as the demand for the current Great Song Dynasty?!" The people of the Great Song Dynasty are not worried about the equipment robbing the workers of their work------ anyone can process the equipment in the same way, and how much cotton cloth can be sold! ”

Yes------ Da Song is actually far from being as glamorous as it seems, and there are still people who wear paper clothes in this era!

In the real Song Dynasty, cotton cloth was not produced much due to poor cotton quality and little production. There are also linen cloths, but due to the limited processing capacity, the price is not low.

As for those silk fabrics made of silk, due to the unstable production of silk, its price is increasing day by day, so the average poor person often uses paper to make clothes.

Wang Yu's poem "Taoist Clothing": "Brown soap scarf of crown cloth." "Fortunately, there is quinoa to cook porridge, why shame the paper as a shirt."

It was the main raw material for papermaking at that time, so it was called the crown.

In addition, the poor people also use paper tents, paper quilts, paper clothes, etc., ------ quality of these things can be imagined.

As long as production increases and prices fall, the demand for cotton cloth is almost endless------ and this is not counting the huge demand elsewhere.

The exchange of cotton cloth for silver ore and labor in Japan made the Japanese daimyo happy.

Wang Defa said optimistically: "It's okay------ we have already started the pot camel engine power, waiting for the big flywheel diesel engine power, they won't be able to learn it for a while!" ”

Island Master Zhang had to nod in agreement, but immediately thought of another question.

"We have taken a close look at the hand-cranked sewing machine technology, don't let them steal it again!"

"Don't worry, they can't process it without machine tool technology!"

In fact, the two of them underestimated the hand-forging ability of the blacksmith in the Great Song Dynasty------ and soon, there were hand-cranked sewing machines sold in the Great Song market, and the price was not low!

If you knock it with a hammer, you can knock it out?!

Director Hu Zhenbei said disapprerovingly: "What's so difficult about this? Even if I don't use a machine tool, I can still do it by hand-------"

Zhang ignored his bragging, and immediately wrote a letter to Jia Yidao, solemnly criticizing the infringement of the patented technology of Liuqiu Island by the people of the Great Song Dynasty, demanding that Jia Pingzhang carry out fair and strict management, and demand a certain amount of economic compensation with the copyright law that the Great Song Dynasty already has!

Jia Pingzhang Jia seemed to be calm at this time, in a very good mood, and was starting his whole person movement, when he suddenly received a letter from Liuqiu Island, he was quite happy, thinking that Zhang Island Master could give him any good ideas.

It is a good way to use the affairs of the northern border to divert domestic contradictions.

As a result, he took the letter handed by Ambassador Hou Dongfang and saw that it was such a trivial matter!

He smiled and said, "Books, they are written by literati with painstaking efforts, and any pirate is a person who is unscrupulous and vicious------ even if he is a pirate, he is not a good person."

The so-called machine and that machine are really made by the owner of Zhang Island, and after my Song Dynasty craftsmen imitate it, it will benefit the people.

Plucking a hair and benefiting the world, why should the owner of Zhang Island be too careful? ! ”

Ambassador Hou Dongfang was just about to speak, Jia Rudao waved his hand and said: "Needless to say, under the persuasion of the old man, there are big families who want to buy Liuqiu paddy fields, millions of acres of transactions, how can they not compare with this machine and that machine?"

By the way, the old man also brought twenty young ladies from his hometown, and let the owner of your family arrange a marriage, I heard that his houseboys are almost at the age of considering marriage. ”

After speaking, he looked at Ambassador Hou Dongfang with a smile, and said, "It's better for you to choose one first." ”

Ambassador Hou Dongfang was speechless for a moment, and his face was a little red. 8)
