In the current Ming Continent, Hunan, Hubei, Anhui, Jiangxi, and even further Shanxi, refugees are constantly fleeing from south to south every day, dragging their families and mouths.

Fortunately, they were able to stay alive, and the whole family escaped to Guangzhou without losing any of them, and found a place to build a shed in the mountains north of Guangzhou and settle down. No one counts them as illegal construction.

Men and women can go into the city and find work...... Most of them fled early, and resolutely and resolutely, without any nostalgia for the little land in their hometown...... They were really lucky.

However, there are also people, who are not lucky or unlucky, who have lost their loved ones on the road and watched their loved ones die on the road or be killed at the hands of thieves and bandits. Only individually or a few of them have come here, at least they themselves are still alive...... To be alive is to have hope, isn't it?

It's nice to be alive, but what is it like to live in the midst of constantly reminiscing about the passing of a loved one? Will it be torture?

But at least it's better than people whose whole family dies silently on the road, who live like ants and die like ants......

Most of the people who are alive have exhausted their silver taels and physical strength during the long flight, and they can only sell their relatives or themselves in the human market.

The city is also divided into two places, one in Nanguan and one in Dongguan. The people market in Nanguan is relatively formal, it is the earliest to be established, and the management is relatively comprehensive.

Not to mention the large number of traffickers and tooth merchants there, the governor of Guangzhou Prefecture has also set up an office here to handle the formalities of trading and trading, and of course, to take care of tax collection. The human trade here is regular, so of course the quality of the "goods" is relatively high.

So the first place to be rectified was here.

On this morning, Nanguan Renshi opened as before, with shopping, lounging, and business, and people coming and going, so it was not lively.

Suddenly, for some reason, two teams of people came and surrounded the entire market with great momentum.

Wu Wenmin, the deputy general of the water commander, straddled the horse, held the treasure knife at his waist, and shouted at his subordinates with a smile: "Don't hurt people, especially women...... The naval guns are all counting on them......"

The soldiers shouted, "Oh! ”

The soldiers rushed into the market, and all the "goods" they sold were gathered. Good fellows, there are more than 1,000 people in one heap!

Wu Wenmin, the deputy general of the water division of the water division, frowned, this woman only has a few hundred people, and only a hundred people who fully meet the standards are worth an 18-pounder gun......

Wu Wenmin, the deputy general of the water division, jumped off the horse and walked towards the pile of women, and the women lowered their heads in fright. Wu Wenmin, the deputy general of the water division, smiled and said, "General Ben wants to find a good place for you, a place with plenty of food and clothing, don't be afraid, raise your heads!" ”

The women were even more frightened, and some were crying. Wu Wenmin, the deputy general of the water division, was on fire in his heart, but he couldn't hear it in his words, he waved his horsewhip and said, "Drag out the appropriate place first......

A few healthy women behind him rushed up, or not that women look at women accurately, they didn't bother, and at a glance, they accurately dragged out the younger ones with better faces in the female crowd.

Seeing that the healthy woman's movements were a little big, Wu Wenmin, the deputy general of the water commander, hurriedly said: "Slow down, Hugh is going to hurt a ......."

Once counted, there were only 103.

At this time, the official in charge of this place finally squeezed over and arched his hand: "General Wu, this is all a legitimate businessman doing business, why is this so?" ”

Wu Wenmin, the deputy general of the water commander, said very politely: "The two governors of Guangzhou, Lord Du, and the governor of Guangzhou, Lord Sun, have ordered that this market will be taken over by us for the time being, and all the goods will be handled by us for the time being. ”

After speaking, he took out an official slip and handed it to the official, who bowed down and took it with both hands, and took a closer look, what he said was true, and the official seal of the Guangzhou Mansion was impressive!

Wu Wenmin, the deputy general of the water commander, said gently: "You can also go to Lord Du, the governor of Liangguang, to certify......

The official retreated and said in his heart: I am sick! I'm going to certify......

Seeing that things were not good, the tooth merchant hurriedly ran to see the staff of Wu Zhengguo, the chief judge of the Guangzhou Prefecture, and everyone knew who covered this market.

Wu Wenmin, the deputy general of the water division, didn't pay attention to anything else at all, he touched his chin and looked at the rest of the women, as if he was looking at a piece of artillery.

After a while, he had an idea, and he whispered a few words to a healthy woman, who immediately understood, so all the healthy women deliberated, and went into the crowd of women separately for a long time to persuade them, and all of them were done.

Wu Wenmin, the deputy general of the water division, slowly walked up to a woman in her thirties and asked, "How old is Fang?" ”

The woman trembled and said, "So that the general may know the way...... I'm 19! ”

"Why is your face so old?"

"I ......"

The healthy woman next to her was angry, slapped her on the back, and almost knocked her to the ground, saying: "The laborer, how can the face be tender if the wind and the sun are blowing!" ”

Wu Wenmin, the deputy general of the water commander, nodded approvingly: "I see, it makes sense......"

In this way, more than 400 women are complete. But that's far from the ideal number. They are said to have more than 100 Hongyi cannons, and they don't get all of them into their hands.

What was the cannon of this period? It's power, it's money! Everything in everything!

However, there are still preparations for the future, and he is not too urgent now.

The men can't let it go.

That night, Zhou Fu casually said that there was a shortage of professionals there. Then, under the "training" of Wu Wenmin, the deputy general of the water control division, these men will probably soon become all-rounders, and they can do whatever they want. How can you top a number when the time comes?

Outside the old city of Guangzhou, the Dongguan people market in the new city is spontaneous, and refugees who have fled the famine have sold themselves or their families by planting a straw mark here. In less than a year, a market was formed here.

If there is a market, managers will emerge, and dozens of ruffians will take care of it, and they will be responsible for managing it. Of course, it can also be said to be contracting, and they have to pay a certain fee to someone in the government. Because the grade here is too low, the big guy can't look down on it, so of course it's left to his subordinates.

When Zhang Yue, the deputy general of the army army, rectified here, it was easy, and he didn't even give an explanation, just one sentence: "Take it all away!" ”

There was also a rotten boy leader who came over slowly, with a smile on his face, and wanted to ask what was going on, but a soldier swept over with a gun, and the rotten boy leader lost all his teeth, and ran away with a snort.

Zhang Yue, the deputy general of the army army, snorted with satisfaction after hearing the shout. Good soldier, I know my old Zhang's intentions. After a while, Zhilu will promote him after his name and surname.

No matter what era it is, it is easy for the scumbag army to clean up the underworld. Of course, if this underworld is run by the bigwigs of the DPRK and China, it will be different.

It won't be until another bigwig brings down this bigwig, and the masses who don't know the truth will know, oh, this is an underworld!

After Zhang Yue, the deputy general of the army army, collected the goods, and after taking a glance, he was suddenly furious in his heart, what the hell is this! Are there any trees under the age of 30? Can a woman look like this?!

No matter what, leave it to Angkor to deal with...... Zhang Yue, the deputy general of the army army, thought of this, and his heart settled down again.

Next, Guangzhou began a vigorous anti-pornography campaign, those who were not more than 30 years old, did not have a fixed place of business, or the place did not meet fire safety - the reason is that your place is too small, all the warblers among them were taken away, and the tools of those illegal operators were confiscated for artillery. Of course, they didn't touch the high-end places, and there were big guys covering them, and they had already said hello.

After looking for a medical examination—those who were outsiders actually knew that a woman could still have fir disease—there were as many as a thousand people who were qualified. That should be enough.

A thirty-six-pounder cannon costs two hundred women, while a four-pounder cannon costs four.

There is a reason why Manager Meregg set the price like this, and he also sincerely asked Director Li Ziqiang.

This is mainly due to the level of machining in this era. Although in the past, every time Director Li Ziqiang chatted with him, he asked him to write on paper first, but when the network signal covered from the city of Relanza to the Red Star Industrial Zone, there were more and more questions between them.

Director Li Ziqiang thinks it's okay, and at least he has time to react when talking to Manager Mei Lezhi.

As mentioned above, even in Europe, "those who can get two or three usable can be called masters if they cast ten guns."

In other words, the scrap rate of heavy artillery is as high as 70~80%. In this way, the cost of heavy artillery will naturally not be reduced.

The most important and fundamental reason for such a high rate of artillery casting scrap at this time is the difference in cooling rate between the inside and outside of the barrel. Due to this difference in cooling speed, many barrels made of poor material and not uniform enough will cause cracks in the barrel due to thermal expansion and contraction during cooling. And the barrel with a crack in the barrel is naturally a scrap.

Not only that, some of the cracks are not visible on the outside, but inside the metal of the pipe wall. Therefore, at that time, all the well-made artillery guns needed to be tested for the first time. That is, the barrel is filled with gunpowder but not loaded with shells, and it is released once, and the one with no crack in the pipe wall is qualified.

If there is an internal injury to the pipe wall, this release will crack open and can be eliminated immediately.

Of course, the ancients did not have ultrasonic flaw detectors and could not test them beforehand.

But it is precisely because of this thing that the traversers have become less courageous, and after measuring the pipe wall, they have no intention of even trying to fire the cannon. There is no brave adventurous spirit at all-

In addition, when casting super-large caliber guns, especially fortress heavy guns of several tons, the larger the caliber, the greater the difference in the cooling rate between the inside and outside. Thus, in the era of natural cooling, the higher the scrap rate of cannon casting, and the weight and price soared dramatically – not proportionally, almost exponentially.

At a certain point, it is almost 100% of the failure rate. Therefore, at that time, it was rare to see iron super-large caliber guns, the largest was only 8 inches, that is, about 45 pounds, and it was difficult to make even larger guns.

If only one of the 100 large-caliber guns can be used, it does not mean that the cost is only the material price of the successful cannon alone, but it should be calculated according to a hundred!

So the price of a 36-pounder gun can even be equal to the sum of the prices of dozens of 4-6-pounder field guns! Of course, dozens of 4-6-pounder guns can only leave some shallow pits on the city wall when attacking the city with dozens of salvos, and the city wall is not greatly damaged, but a 36-pounder cannon and dozens of shells can completely destroy a section of the city wall, and this is especially important in naval battles against rough-skinned battleships, and it is precisely for this reason that Wu Wenmin, the deputy general of the naval division, is extremely eager.

On land, the power of a heavy artillery piece is far from being comparable to that of dozens of small artillery pieces when attacking a city, and of course, against infantry groups, heavy artillery is not as powerful as small field artillery.

Therefore, there is a reason why Zhang Yue, the deputy general of the unified army army, is so busy and dizzy.

And those firecrackers are also very important! Zhang Yue saw three hundred Portuguese mercenaries with his own eyes, and he shot more than a thousand Qing soldiers in one impact! Zhang Yue, who was watching the battle in the city, suddenly understood the power of the arquebus. The thought that he might also be able to form this team of 300 people made him happy!

If that's the case, he's scared! What is this official and that bandit......

I'm here, I still need some water, I'm not afraid of scolding.

The cost problem of this heavy artillery was not solved until the nineteenth century when Rodman invented the water-cooling technology of the inner mold, which can ensure that the cooling speed of the inner and outer tubes is the same within the conceptual range, or after repeated experiments and adjustments, the speed difference is controlled within a safe range, so that the body tube will not cause internal injuries.

This immediately reduced the scrap rate to a single-digit percentage, or even to zero, resulting in a significant reduction in the price of a cannon. And the cannon itself is also relatively strong and has no dark wounds, so the average life span is increased by five times.

This kind of technique cannot actually improve the combat performance of the artillery such as the firing range and power, which is a problem in the science of metal materials, but just looking at the fact that it can greatly reduce the cost of cannon manufacturing, it is a very valuable technique.

When this technique spread in the European Common Market due to the frequent interaction of white people, they invariably set up technical barriers to civilizations outside Europe.

The descendants of the Ming people are sad again-

Some people will say that in the 19th century, we also had iron mold casting technology! Yes, my liberal arts classmates, that just solved the problem of the speed of casting guns, and of course saved the cost of molds...... But in terms of caliber did not help, and in my opinion, progress was limited.

If the two means can be combined, it will be a qualitative leap...... Hey, there's some perfect philosophical meaning.

Again, I have to say that.

Therefore, at the end of the Ming Dynasty, the Hongyi cannons in Europe crossed the ocean to the Ming continent, not only the material price and processing cost of a single artillery, but also the problem of the scrap rate of artillery processing.

The Hongyi cannons sold by European merchants to the Zheng family sailors were also several thousand taels and one doors, and this was not only a matter of freight, but also of the scrap rate - all for a reason.

Manager Merges set a "reasonable" price of four to twelve pounds for ten women, eighteen pounds for a hundred women, and thirty-six pounds for two hundred women, without going into any further detail—even knowing that people might think of themselves as fools and whores!

But, thinking of the Ming people who can be easily saved, a fool is a fool - may my Chinese children suffer a little less - may the sun always shine on my Chinese children -

As for the firecracker gun, five women in one gun, it's really cheap, and the traversers are really stupid.

On the Internet, none of the time-travelers objected to this exchange, and some even offered to give it to the Akito in vain with tears in their eyes, so that they could have more resistance in next year's massacre.

This person is Fan Weiye, at that time, he was still posting with his small hands quickly, could it be that in the face of major rights and wrongs, can we still care about how many women we can exchange for? I don't think that's right, the Manchus are slaughtering our Ming people, but we are still developing unhurriedly, exploding soldiers, exploding guns and cannons to slaughter them in turn!

At that time, there was silence on the forum, but he soon had a reply, which was Jiang Xue's.

Jiang Xue said kindly, shut up! Listen to the uncles!

The foolish behavior of the traversers has aroused the desire to consume in the military department of the Akito, and the women are still not enough!

One afternoon, more than 1,000 soldiers suddenly appeared in the mountains north of Guangzhou. This is a dragnet-style clean-up and rectification, and the female refugees will not be able to escape this time, and they will all be retracted.

What made Zhang Yue, the deputy general of the unified army soldiers, look down on him, and many big men actually cried. Facing the scene of chickens flying and dogs jumping, he laughed loudly, kept comforting the BMW under him who seemed to be frightened, and shouted loudly: "Wait and cry!" When people come from Taiwan, you will cry loudly again-"

Zhou Fu once said that these fools can't see the Ming people suffering, although they are good at kicking the Ming people's buttocks, they can eat the same food, which is embarrassing - even when the Hongmao people work for them, they actually eat the same food, which is ridiculous-

If this comment is heard by the people in the cafeteria, they will definitely shout aggrieved, your sister, we have the spare time to cook two meals!
