Ambassador Hou Dongfang had to truthfully report the negotiations with Jia Yidao and Jia Pingzhang------ the transaction of millions of acres of paddy fields was really huge, and he also sent the twenty young ladies back to Liuqiu Island.

Ambassador Hou Dongfang knew that his quiet master would definitely educate them well.

After receiving the reply, Zhang couldn't cry or laugh, this old guy probably thought he was a miser.

Maybe it's because you're ahead of your time?

The Great Song Dynasty government can protect copyrights, but not patents------ strictly speaking, maybe they still pay more attention to literature than reason.

But it's quite humane------ his houseboys are really going to get married.

Forget it, I don't know the same as the Great Song Dynasty, but fortunately, there are still a lot of profiteering products on the Great Song Dynasty on Liuqiu Island, and I am not afraid that the Great Song Dynasty will infringe on its own patents, nor will I be afraid of spending all its hard currency.

The bone china produced on Liuqiu Island is a commodity that Liuqiu Island can compete with the official kiln products of the Great Song Dynasty in porcelain, and if it were not for its low production, it would definitely make a lot of money in the Great Song Dynasty market like glass products.

The Great Song Dynasty is now in a period of stability, and the large market of more than 100 million people is enough to ensure the rapid development of Liuqiu Island.

Zhang Daozhu paid close attention to the secrecy work, and the relevant technology would never be stolen by the Great Song people again.

There is also a mechanical product that can be sold in the Dasong market------ large and small grandfather clocks produced on Liuqiu Island.

In order to make it convenient for the Song Dynasty people to use, Zhang Daozhu designed the table clock to be 24-hour type, corresponding to 12 hours at the same time.

In order to simplify the structure, the second hand was also removed, and only the hour and minute hands were used------ the Great Song people of this era could act in minutes, which was considered to be extremely fast.

Wang Defa's main family has specially manufactured a variety of small machine tools and processing tools for the grandfather clock processing industry.

In fact, for the craftsmen they trained, parts that are too big or too small are not easy to machine------ but small are just right.

Therefore, the standing table clock they produced looks too large, and the specifications are 1.5 meters high and 30 centimeters wide!

In the eyes of Zhang Island Master himself, the table clock looks like a twelve-inch black-and-white TV!

It's too big-------

Hu Zhenbei, the director of the factory, does not allow others to have opinions on the products he manages.

"What's the big deal? The more so, the more magnificent! ”

Director Hu worked the hardwood appearance of the table clock------ not carved with various patterns to inlay gold and jade.

Zhang often checks their products, and the problems are different for each batch, either a few minutes faster a day or a few minutes slower.

Director Hu also defended that where do they have Yin Di'an's technology, they will not delay anything for a few minutes!

Zhang can only ask him to write clearly in the manual, and let the family adjust it themselves when the time comes.

Director Hu readily agreed, and said that he would place repair hours in Lin'an City and other big cities, and when the time comes, you can go to the door to adjust!

Liuqiu table clocks are selling well in major cities in the Great Song Dynasty, and the basic goods are empty------ and the scheduled goods are enough for them to work for another two years now.

Recruit young and clever apprentices!

The huge profits allowed Director Hu to summon young workers on the whole ship------- and even the wages offered by Director Hu could allow the young people in the inland cities of the Great Song Dynasty to come to the island by themselves!

In the coastal cities of the Great Song Dynasty, even the ordinary county towns have ships to go to Liuqiu Island------ the previous huge investment is getting more and more huge returns.

Zhang Daozhu and Wang Defa were happy to see it, and wherever their "Liuqiu Times" was published, their recruitment was widely advertised, except for the children of rich families, almost all literate young people would be tempted to read it.

In less than two years, as long as they learn the technology, their wages will be comparable to that of a magistrate!

Money touches people's hearts.

There are also early mirrors, dyes and flavors, soaps and other products, which still make huge profits from the Great Song Dynasty.

However, this profit did not stagnate, and was put into the treasury, but immediately invested in the Great Song Dynasty, buying raw materials, recruiting personnel------ or investing in various urban construction on Liuqiu Island.

The city of Eight Rivers is now expanding like a balloon that has been blown up.

The Eight Rivers became a major artery connecting the entire city.

Zhang was annoyed by the cars and boats running back and forth on the Badao River, and each boat on the river was busy transporting passengers and goods, which usually took up ten to twenty oarsmen, which was a serious waste of labor------- even those people who went to the river to fish for iron ore were better than using it like this.

After being shocked by Zhang Daoist last time, the factory director was completely fascinated by the design of the pot camel engine steamship------ of course he couldn't imagine the correct marine power output of the propeller type, and finally produced two ship models.

One is the rocking type, the other is the car and boat type------ that is, it carries two paddle wheels.

This is already the extreme of imagination that an experienced shipbuilding craftsman of the Great Song Dynasty can reach.

Zhang Island Master didn't joke this time, he directly picked up the rocking boat model and said, "Give me this------ it doesn't apply, the power is extremely low."

That paddle wheel is OK, it can be used in the river and sea, and it can be used as a passenger and cargo ship on both sides of the strait.

Do you have the hydrological data of West Lake? ”

Director Zhang Laoshi immediately said: "Yes, yes, even the Grand Canal!" ”

"Well, the paddlewheel has a shallow draft, you can ------- up the canal"

Zhang Laoshi's eyes sparkled and said: "If you step on it with people, you can't go to sea without 300 people." ”

"I know------ we use a pot camel machine, we don't pursue speed for the time being, fifty horsepower is enough!"

As mentioned above, the pot camel machine is a general term for a kind of power machinery with a boiler and steam engine.

It is characterized by simple structure, easy operation and maintenance, and has the advantages of light weight and small size, which can be moved and transported and fixed installation.

Generally speaking, the excess horsepower of the pot camel machine is relatively generous, and it can be used for a short time by more than 20%, and there is not much harm to the machine itself.

Zhang Daozhu: Before they crossed, they had studied the pot camel machine very sufficiently------ because their processing capacity was just right.

Now on Liuqiu Island, there are hundreds of five- to twenty-horsepower pot camel machines!

Industrially, they are mostly used as a mechanical power source; Agriculturally, they are more useful, leveling the land, pumping water, threshing and milling, and so on.

This is the first time for marine power ------, and the output power requirement reaches 50 horsepower, which is a challenge for Wang Defa's family, in fact, it is also a challenge for the processing capacity of the convection island.

Wang Defa's family said to Zhang Daozhu: "It's not a thing------ the best cost-effective power of the pot camel machine is within 120 horsepower, and we still have a lot of room to rise." ”

Zhang said happily: "Then the power output of the propeller type is not difficult?!" ”

"It's not difficult, you can cast pig iron, you can also hand forge bronze------- if you use a vertical shaft installation, the output end is higher than the water line, then there is no leakage problem, but the structure is more complicated!

If the flat shaft is installed, the brass sleeve is installed to be waterproof, how much water can leak, and ------ arrange a special person to drain the water regularly.

It's not that you don't know that in the era of sailboats, how can there be a ship that does not leak?? ”

"Let's get on the two boats together! Save time!! ”

"Okay, I'm just going to concentrate on manpower to process the marine horizontal pot camel machine, and when I take out the rough specifications, you let Zhang Laoshi start work!"

At this time, the two bird-type seafarers returning from Baimadu on the Yellow River had just docked, and their time was outrageous, and their time was mostly wasted waiting for the wind------- whether it was a paddlewheel or a propeller sailboat, they would change the era.

Later, much later, the owner of Zhang Island identified the launching of the two sailing boats as the maritime culture of Liuqiu Island.
