"Then why are they only donkeys and mules, and not cows and horses?"

The man from the coal mine pointed to the strange big iron pot in the distance, still curious.

"Why? Air leakage. Now those water-driven, foot-pedal knife beds, it's okay to drill the barrel of a musket and make something this big...... Can't get it. ”

"Let's put it this way, when our cannon can hit two miles of land and can hit a house for two miles with a single shot, I will be able to get cattle and horses, not this broken donkey. Sincerely, this is true. ”

This is not a lie, the principle is sometimes quite simple, especially with the existence of a person who has studied 2,000 years of human experience.

But the difficulty lies in the materials and precision.

After the improvement, the efficiency has been improved, and the steam engine can be used for large-scale use, due to the development of military science and technology, there is an urgent need for a boring machine that can boring cannons, and there is no boring machine that can boring cannons, so there is no way to process pistons and cylinders with an accuracy of about two millimeters, which leads to air leakage everywhere.

It's not that it can't be used, but there is no way to promote it on a large scale, and the cost and efficiency are too low.

The division of labor in Sishang is already using water-powered and foot-driven beds, but it is also a matter of sharpening a screw and passing through the barrel.

The principle of the steam engine is very simple, the small model can be made with a file and cast copper, but it can not be used when it is enlarged, because the piston does not fit the cylinder and causes air leakage.

If the cylinder can be dug out with a perfect cylindrical bore, then the cannon can basically be hit wherever it can be within the firing range.

The man in the coal mine didn't seem to understand, so he sighed and said, "I also look forward to seeing it sooner." There is really a shortage of people, there is a shortage of people everywhere, those who can use machinery, cattle and horses, wind and water, we can really use machinery without people, but it is still not enough. ”

"I'm pulling carts and draining water, and I have to prepare dozens of horses, thirty or forty people. If your machine could really be used, it would save dozens of horses and dozens of people. Extending it to coal mines, it can save hundreds or thousands of people, right? ”

The man from the machinery factory snorted and said a little embarrassedly: "This coal-burning mule also has to use people." Some switches have to be turned on by people. When to release water and when to turn on the air...... However, there are few people who use it, and women can do it. ”

"I can still improve it, said the giant, first go up, let the world know that steam and coal can really be used as mules. As for the rest of the improvements, take your time. ”

"People, it is one that can save one. Look at the people who run workshops now, to what extent are they jealous of people? Those who fled must first go one-third of the way through the official camp; The other third went to work in the reclamation, and the rest could be hired. ”

"Those people were looking forward to war a while ago, what should you be looking forward to? Hopefully. Looking at those people who couldn't move in the aristocratic fiefdoms, their eyes were red. Let me tell you, those nobles just occupy the pit and don't, and the same people are here with us, and they can produce three or five times as many things in their hands. ”

After a hard whining, the strange iron lump was also transported, this is the most primitive coal-using machinery, and a large stove pit needs to be erected underneath, and people are also needed to be responsible for switching on and off the cold water, and it may be possible to achieve an energy conversion rate of fifteen thousandths according to the efficiency they don't know.

But if the population is larger, this thing is really difficult to promote, but now there is a shortage of people everywhere, and it is the easiest time to promote.

The population explosion of later generations led to intensive farming, from cattle and horse farming to human farming; Almost inexhaustible manpower, stability has become a premise, and without strong organizational ability, it will always be reincarnated if there is no strong organizational ability to survive the severe pain of replacing people with machines.

Whether it is sheep eating people or machines replacing people, for a huge population, the pain will be a major event involving the life and death of tens of millions of people, and no one dares to move.

Now, there are few people, there is a shortage of people, and many of the pains that should be there do not need to be beared, and a strong organizational force can put people into the planned reclamation and development.

Technology is not science, and there are some things, technology tends to get ahead of science, especially something that is really not too difficult.

This era belongs to craftsmen who can do it.

And those who hide in the Xuan Xuan to study the "Heavenly Will" belong to the future.

If you don't understand the principles of mechanics, don't understand the mechanical principles, don't understand the decomposition of mechanics, you can still make water drains, windmills, connecting rods, and even knock out some things that should not belong to this era under inspiration and guidance.

Even in chemistry from scratch, as long as someone understands some principles, as long as they are not afraid of the dead, they can jump up with a limp.

But jumping up with a limp will always fall, and those who hide in the Xuan Xuan Gao Pavilion and other people who study the mystical heavenly chronicles are the ones who put wings on them.

It's easier said than done, and this is very applicable to Sishang, because there is a person who knows in Sishang.

But as for the work, many of them started from scratch, relying on prophets, piling up human lives and time.

Materials require thousands of attempts, and the people at the Machinery Factory know the key to this all too well.

There are some things, as soon as the principle is said, can be done now.

For example, alum acid, if you don't know how to make this thing, then it is impossible for Sishang to have the kind of expensive medicine for heartache that is sold to the princes and nobles.

Some things, as soon as the principle is said, may take ten or eight years to figure out the clue.

For example, alum acid, the largest alum acid workshop in Sishang now uses a lead room, but the lead is too soft. The lead chamber is inefficient if it is small, and it is easy to deform when it is large, so what should I do? The exterior is surrounded by a wooden frame, pasted with grass and mud, and a wooden frame is made on top to hang the lead roof......

Another example is the simple-sounding leaf spring, the principle is too simple, elastic accumulation, firing flint, but it has taken ten years to make a leaf spring that is elastic enough.

…………

The man who installed the primitive coal-burning machine called "next door" was buzzing at this time.

A few men carefully fished out a curved leaf spring from the melted lead water with pliers, as if it were a fragile piece of porcelain, and seven or eight people stared at the tiny, perhaps finger-long, thing.

As the man who complained next to the coal mine said, ten years have passed since the establishment of the leaf spring.

The reward of 100 gold is to beat the rabbit with grass to the outside, hoping that some craftsman will inadvertently make it suitable for use.

Internally, they are divided into small groups and try in different ways.

As the man said, all the quenching methods that could be used were used.

It wasn't until I tried to use "lead", which has a higher melting point than oil boiling, but is much lower than bronze, that I melted the lead and tried to quench it, and finally made a breakthrough.

The previous few days seemed to work, but this time it was a repeat experiment.

Carburized steel is first forged with wrought iron, then quickly quenched with water, and after quenching, lead is turned into a crucible.

Then put the leaf spring quenched in water into the lead water, wait for the lead water to solidify, then melt the lead, pinch it out with pliers, and cool it naturally.

The specific principle, they do not understand.

As for the means, it took the No. 100 people ten years to try the means of quenching with a lower melting point than the ironmaking temperature.

Expensive castor oil, sesame oil, I don't know how much it costs.

I don't know how many strange things have been added to the quenching water.

Just a few days ago, a leaf spring that seemed to be qualified was finally tested.

The people who are in charge of this today, who have changed from young men to middle-aged people, are gathered here, waiting for the results for a while.

In front of the cooled leaf spring, silk threads were tied, and the experimenting craftsmen carefully added weights underneath.

When the weight of ten catties was pressed up, the leaf spring that carried the hard work of more than 100 people for ten years was still persistent, and the crowd had already shouted excitedly.

"Fifteen pounds! Fifteen pounds is enough! As long as you can use fifteen catties of force, you can rub the flint, so that the fire rate is about seventy percent. ”

"Hold on!"

The craftsmen, who had been struggling with this for ten years, shouted in unison, as if the leaf spring could hear their call.

The craftsman in charge of adding weights had sweat on his forehead, and he put another pound of weights on it, then cut short silk threads and bounced straight with a swish.

Tie the silk thread again, repeating the original action, and many people's hearts seem to jump to their throats.

Twelve pounds.

Thirteen pounds.

Fifteen pounds.

Eighteen pounds......

When the last weight was put up, the moment the thread was cut and straightened again, there was a roar in the room.

"It's done!"

"It's done!"

"Fuck the arquebus! Never again! ”

A gray-haired craftsman suddenly fell to his knees and began to cry.

His son, while in the service, died of the burning of gunpowder caused by the firestring, which was a very common incident, and it was normal for this kind of thing to come seven or eight times a year.

And the young man who had been in charge of making leaf springs since he had learned something systematically from the following, stretched out his hand to stroke this small leaf spring.

He was sure that his children had not been touched so carefully when they were born.

More than 100 people, ten years of hard work, is such a small leaf spring.

He bent the leaf spring hard and aimed it at his leg, and suddenly let go, and the huge elastic force whipped his leg with a sharp pain, but he laughed.

No one thought he was stupid, and no one thought there was anything wrong with laughing and crying.

For nearly ten years, all of these people's lives revolved around this little leaf spring, and it took them ten months to give birth.

In their eyes, this small leaf spring is the military merit medal on the chest of the soldiers, the truth in the books written by Mr. Xu, the Mo family built by Zi Mozi, and the world divided by Zhou Gong......

That was something that people will still remember many years later, and that is the greatest pride and the greatest achievement of their lives so far.

The child who used to study is now middle-aged, and now, he can be regarded as relieved.

The gift that Mr. gave him back then, he spent ten years of youth and finally paid it off.

After the person in charge laughed, he didn't talk about the significance of this thing for the benefit of the world, because there was no need to talk about it.

He held the leaf spring up, but said something very lifelike.

"Go buy a firecracker! Celebrate. ”

"Go directly to the branch and receive the 100 gold!"

"Rest for a month!"

"Send someone, hurry up, go to the city to buy tickets for the theater, go to the best wine shop, get drunk tonight, and watch the play the night after! The number of votes was bought according to the wife and son. At tonight's wine banquet, I also brought my wife and children! Go directly to the account, and then make up the money after receiving it. ”

Rumble......

The crowd immediately erupted in spontaneous applause, and when even two people hurried outside, the roar of firecrackers resounded throughout the workshop.
