The end of the Ming Dynasty swept the world

Chapter 673 Simple Steam Engine
Ding Yi looked around Xingang City for a while.

Behind this section of the city wall on the west side is a large amount of hoarded land, which was moved by a few cooked farmers such as Dadu Society. The hoarded area is about [-] mu, [-]% of which is rice and wheat, and [-]% is sweet potatoes, potatoes, and corn.

Then 1000 meters to the east is the second section of the main city wall. The height of the main city wall is getting higher and higher. At the beginning of the design, it was seven meters, then nine meters, and now it is 12 meters.

There is also a fort at 100 meters and a blockhouse at 30 meters. The forts here are all 6 pounds, 12 pounds, 24 pounds, Francois machines, etc.

Among them, the 24-pound gun was also purchased from the Macau Copper Factory, and the 6-pound and 12-pound guns were made by Ding Yi himself.

Now they bought the cannons from Macau recently, and made the small cannons themselves, so as to speed up the deployment of artillery here.

Because there are too many cannons here, Xingang City and Tainan City alone need hundreds of cannons, and Ding Yi can build them himself. I don’t know how long it will take.

After more than four years of construction, Xingang City is almost complete, and the facilities inside are very complete, even better than the city built by Ding Yi in Lushun.

There are also high-standard sewers and drainage designs. There are rivers dug out in the city, and dozens of wells are added to provide food and water.

Now [-] people have lived in it, and [-] soldiers and horses have been added. After the successor is complete, another [-] people will be moved to it.

The gun factories and gun factories in the city have been completed and put into operation, and can repair guns and guns.

With the addition of the craftsmen brought by Ding Yi at this time, in the future, we will start to manufacture Francophones, 6-pound guns, and Lumi blunderbuss, but not 12-pound guns and flintlock guns.

Starting next year or the year after, the 12-pound gun and flintlock gun will be rebuilt and gradually upgraded.

After watching Xingang City, Ding Yi is still quite satisfied. Xingang City is huge in scale. After a large number of newcomers and familiars live in it, they have gradually changed their living habits with various commodities, entertainment facilities, dramas, shops, etc. , let them integrate into the current life, and thus recognize the arrival of Mingren.

Because Ding Yi will pay the salary and hire the original residents to work, and he can use everything in Xingang City to recover all the money.

If the original residents are not allowed to spend money, Ding Yi's money will become less and less. We must find a way to let the money of the residents here flow, and finally return it to Ding Yi's hands.

For example, Zhao Dashan's wife, Mihaer, the daughter of a former headman, a brutal girl who only knows how to use animal skins, now wears beautiful and bright Ming Dynasty dresses.

And according to the dressing characteristics of the fans, Ding Yi also designed the miniskirts of later generations here. Mihaer also gradually stopped wearing animal bone necklaces and changed to jewelry necklaces. She is an idol in the eyes of many strangers. and learning objects.

As long as Michal wears and wears what, those raw and mature women who have money will also learn, accept and use Ming people's goods.

It happened to be the beginning of January when Ding Yi arrived, and he visited all the places in Dayuannan that day. The next day was January [-], the monthly payment day of Dongjiang Town. This time Ding Yi arrived, and Zhao Dashan suggested that he pay the salary himself. Yi readily agreed.

Due to the large number of Ming troops, they were divided into two batches, morning and afternoon. In the morning, we saw [-] Ming army infantry stationed here on the school grounds.

Afternoon hairdresser.

When the Ming soldiers saw Ding Yi, they didn't know who was taking the lead, so they suddenly shouted.

"Master Ding."

"Master Ding."

Then the voice became louder and louder, and finally a thousand people shouted in unison, and the voice was agitated.

"Long live Lord Ding." Someone among the soldiers shouted again.

"Long live."

"Long live."

"Long live Lord Ding."

"Long live." The voice was higher and higher, and Ding Yi smiled and watched them shouting in unison, of course he felt very strong in his heart.

The generals standing behind were also excited. Although Mr. Ding was not there often, no one could replace him.

Foreigners and Fanren, including Pilut, were a little surprised. They didn't expect Ding Yi's image in Zhanbing to be so lofty.

The food and salary of the garrison is slightly higher than that of Lushun, and it is rotated at a rate of [-] per year, which means that the soldiers stay here for a maximum of three years, so even if the soldiers are far away from home, they are still acceptable.

And since last year, the commercial street between the north and south ports here has built a blockade and a red building. Soldiers and officials are not allowed to enter the blockade, but they can go to the red building to relieve the distress of being far away from home and family.

In fact, very few soldiers go to the Red House, because the locals allow them to have sex with the original residents and Han girls. Many girls, both new and acquainted, want to associate with Ming people after a few years of integration into life, so this Many soldiers around are dating girls from the original residents.

Zhao Dashan also has strict rules here, communication is fine, don't cause conflicts between the two clans, and must be open and aboveboard, every couple who has a relationship must report it, the Governor's Mansion will collude with the leader of the girl clan, and get the approval of the elders of the other party first, if If you oppose it, you are not allowed to prevent the two races from conflicting because of this kind of thing.

The Ming people are careful here, respect the original residents in everything, and praise them no matter if they are new or familiar.

After the salary was paid, Ding Yi said again: "Brothers have suffered in Dazuo, and the Chinese New Year is coming soon. I will give everyone a New Year's greeting in advance, and each will give one or two more red envelopes."

The six thousand silver was sent out again, and the scene was full of jubilation, and the sound of long live was endless.

Turning back after the salary was paid, Ding Yi said again, the officials of the ministries below the Governor-General's Mansion also paid one or two more this month. The big furniture was overjoyed, and they all expressed their thanks to Mr. Ding.

Ding Yi also said that the money is a little less, but now we are still spending money, and we will make a lot of money in the future, so we will definitely not forget the brothers.

On the day when the salary was paid, Ding Yi couldn't help but find a senior craftsman to set up a trick.

In September of the [-]th year of Chongzhen, the senior officials set up a scientific five-member group to study steam engines.

At that time, the five people were Bohr, Mike, Mito, Ye Atu, and Fei Tier.

Now that more than two years have passed, Ding Yi was also taken aback when he came to a certain compound of the Craftsmanship Bureau.

I saw people everywhere in the courtyard, more than [-] people were busy inside, more than half of them were foreigners, and there were also a small number of foreigners.

It turned out that after Ding Yi left, in the past two years, so-called scientists came to join the senior staff. Zhao Dashan passed the assessment and screening, and selected ten people as assistants to Boer's team.

Some of these people are young students in Europe. Because Europe is now fighting everywhere, they are useless in their studies, and they don’t want to join the army. I heard that they are recruiting people here, so they go to the big officers, and there are also down-and-out physicists. After all, physics in this era Not yet fully defined, unpopular, and their research would not be possible without funding.

And the legendary Dongfang Dayuan is a beautiful place that attaches great importance to various academics.

In the past two years, many European experts and scholars, through pirates and businessmen traveling between the two places, got information from Dazui and came to Dazuu.

At this time, according to Zhao Dashan's introduction, the Mechanical Department of the Master Craftsmanship Bureau has five expert groups, ten members, and six assistants.

The assistants are all local Han Chinese and Fan people.

When Ding Yi came in this time, they were installing a new boiler.

At the same time, there is a very strange device not far from the side.

Introduced by Bohr, this thing is called 'Steam Wheel Ball'.

The steam ball is the earliest known machine that converts steam into power. It was invented by Hero of Alexandria in 100 AD.

The steam ball is mainly composed of a hollow ball and a closed pot filled with water connected together by two hollow pipes, and the water is heated at the bottom of the pot to boil, then turns into water vapor, and then enters the ball through the pipe , and finally water vapor will be ejected from both sides of the sphere and cause the sphere to rotate.

At that time, the steam ball was just a novel plaything without any practical application.

But after hearing the principle of the steam engine last time, Boer felt that it was similar to a steam ball, so he built a similar one and put it in the yard. Every expert who came in could have a look, so that he could intuitively understand that steam The principle of the drive.

After seeing it, Ding Yi also thought it was wonderful, this Boer is really very thoughtful.

It is difficult for you to explain the principle of steam with ordinary people in theory.

Now Bohr has made a steam ball, which is simple and understandable at a glance.

At this time, the people who followed Ding Yi were all staring at the steam ball strangely.

The pot below is burning, and the steam ball is spinning non-stop, which is very fun.

These people look at the steam ball every day, think about the principle of steam movement, and then study the steam engine.

In history, the French physicist Denis Papin invented the pressure cooker in 1679, and then Thomas Seville in 1698 and Thomas Newcomen in 1712 made the early industrial steam engine.

Then Newcomen and his assistant Carley invented the atmospheric steam engine in 1705, and then Watt invented the steam engine with a condenser separated from the cylinder wall in 1765, and finally Fulton in the United States in 1807. Made the first practical paddle wheel propulsion steam ship "Clermont".

From the pressure cooker to the steam engine to the ship, it has gone through more than [-] years and the efforts of several generations of scientists.

They are all standing on the shoulders of their predecessors, based on the experience of their predecessors, constantly summing up, making progress, and finally succeeding.

Denis Papin has not yet been born, he was born in 1647, and there are still a few years to go.

But the birth of Bohr affected history in advance.

We can imagine that if Bohr had not been caught by the officials, he would spend the rest of his life in the restaurant. After his death, his pressure cooker would also disappear in history, and Dennis Papin's pressure cooker was used in the royal family. He worked at the Academy and cooked a meal for Charles II, making his pressure cooker famous and becoming the super master of the world's industrial development.

The fate of life is like this, some people may be unrecognized for their talents and spend their lives in obscurity, while some people will soar into the sky when the opportunity comes.

If Liu Bei only had two visits to Maolu, Zhu Houliang might have been silent in the countryside for a lifetime.

Jiang Taigong only went down the mountain to fish when he was 80 or [-] years old. If he didn't go down the mountain, he would die of old age and no one would know.

Now that Bohr has come to Dayuan, it is estimated that there will be nothing to do with Dennis Papin in the future.

And their research will definitely be more directional than those scientists in history.

Because Ding Yi drew a rough pattern for them, boiler, cylinder, piston, flywheel, a few simple structures, everyone had a very intuitive impression.

In the past, when these scientists studied steam wheels, they also had to consider what components were composed of them and what structures were needed.

Now Ding Yi draws more than half of them directly. Although it is not completely correct, it saves a lot of time.

Ding Yi himself draws casually. After all, he knows the approximate parts of the steam engine he learned in his previous life, but it is impossible to say how accurate the drawing is, unless he knows that he will time travel and remembers it in advance.

But for these expert groups now, it has provided a good research direction.

After more than two years of research, Bohr has gained some insight.

He happily came to Ding Yi and told Ding Yi that the picture you drew last time, General Ding, may not be complete.

We study and study, and there are still few things.

He brought new blueprints.

Ding Yi looked intently, and sure enough, the painting was more comprehensive than his.

"This one alone is a steam boiler, let's not talk about it."

"This is an air cylinder. General Ding named it an air cylinder. I think it is very vivid, but this thing is very difficult to make. We have tried many times, and the effect is still not satisfactory."

"This is the base, this is the piston, this is the flywheel, this is the crank connecting rod, we count this as a valve (sliding valve steam distribution structure), this is for speed regulation (speed regulating mechanism), I think of so much for the time being, but the integration It’s not easy getting up.”

The structure of Bohr's drawings is completely close to the steam engine structure of later generations, but the names of some components are not professional.

Of course, his drawing is not professional now, and he even showed Ding Yi a wooden cylinder model.

It is also the simplest single-acting cylinder.

The cylinder is the core of the steam engine. It is closed at one end and a movable piston at the other end.

Of course Ding Yi doesn't understand, what Bohr is doing now, one end is a piston, and the other end is not completely closed.

But Ding Yi didn't have any suggestions at the moment, he could only say: "There seems to be another theory about this thing, single door, multiple doors, single effect and double effect, I don't know the details, you should do more research yourself."

He has done the limit of what he can do, after all, he is not an expert in this field.

Afterwards, they can only rely on themselves.

Fortunately, Bohr's deputy Mike is a physicist, and many components are not working well, so he came to improve them.

They quickly showed Ding Yi a simple steam engine they newly built.

This steam engine is very rough, the piston runs once, and every time it is delayed for several seconds, there is still steam leaking around, and the piston is weak. It is obvious that there are problems in all aspects and needs to be improved.

"Not bad, good job, a bit immature, come on, hahaha." Naturally, Ding Yi would not pour cold water on him, so he praised him first.

Everyone was very happy, but they also knew that this thing was useless, and they all expressed that they would study and improve it.

After Ding Yi finished watching, he announced on the spot that each person would be rewarded with 500 taels of silver first.

Everyone expressed their gratitude to General Ding.

After spending two days looking at everything about the senior officials, Ding Yi had to listen to the report as usual.

He remembered that when Chongzhen left for ten years last time, he lost more than 70 yuan a year and spent nearly 100 million yuan. If he comes back this time, what will happen?
Zhao Dashan first reported to the military department, and there was no change in the personnel. The large infantry division had 5000 soldiers in the first battalion of the Ming army, 4000 soldiers in the second battalion of Fanjun and Dutchmen, and [-] soldiers in the third battalion of the former Mongolian Jurchen army, totaling [-]. people.

There are also [-] garrison battalions of senior officers.

The navy is four thousand five, of which the Dutch are about three hundred.
