Kerry has changed from the original village chief to the manager of the mine, and many people are surprised how quickly he adapts to this new identity, and in just two months, the production and transportation have been tightly organized under his arrangement. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Susan didn't make it to Tuk City, and after several in-depth discussions with her, Renault decided to rebuild the school in Blackiron Town.

As the name suggests, the top performers in all schools in Tuk will be sent here to study.

The teaching materials and curriculum were personally selected by Renaud and Susan.

Involving literature, mathematics, physical fitness and other aspects, the advanced class will also receive education in the knowledge of demons, the basics of physics, chemistry, mechanics, financial accounting, management concepts, basic combat, etc.

The Black Iron Town School was also officially renamed the "Black Iron Town Higher Education School", which was the first professional school in the entire Auro Continent, and the rich curriculum offered made the royal family amazed.

As time goes on, it's about to be winter again.

The sky has been overcast for several days, and the first snowflakes of the year have finally fallen.

Compared with last year, this year's snow came earlier and more hurriedly than last year, and the Black Iron Town under the sky has changed from last year's deserted appearance, and it looks extremely lively and busy.

The workshops did not stop production because of the snow, and the merchants in a hurry also seized the time to transfer a large number of goods out before the river froze.

Renault came to the machining workshop, the original small workshop of several hundred square meters, has now expanded to tens of thousands of square meters, all kinds of processing machinery and semi-finished products piled up.

In particular, where steam locomotives and carriages are made, there are samples of locomotives that Renault made with mobile phones that have been disassembled little by little, and "knock-off versions" of pipes and parts installed on them with current productivity.

Bypassing the busy work area, Renault, accompanied by Ferré, went underground from the "management room" in the corner of the workshop.

After descending the stairs, there is a long passageway, and a dozen guards in two rows strictly guard the entrance.

This is the "military workshop" of Black Iron Town, in addition to the production of various types of artillery shells, the research and preliminary experiments of new weapons are also in this vast underground space.

Charlotte is dressed in a white lab coat, and her petite stature is especially noticeable in a group of "scientific researchers" who also wear white coats.

She was clutching a handful of bullet casings made of copper in her hand and threw them into the basin on the table with a clatter.

"The quality is passable, but it's too slow. In the face of outsiders, she always has such a one-dimensional feeling, "Find a way to achieve mass production, at least more than 1,000 pieces a day." ”

The people around were silent, they were a group of people selected by Ferry from the workshop, with flexible minds and relatively pioneering power, and they contributed to the transformation of the howitzer.

But against Charlotte, they can't do anything at all.

This little girl, who may be only half their average age, is not the slightest polite because of their age.

It's good not to make mistakes, but if she finds out that she didn't do what she asked, it's not easy to bluff over. Her sense of intelligence and cunning does not need to be superfluous now, and it can naturally be revealed from her every move and from her demeanor and temperament. Charlotte seems to have a sense of foresight, always knowing the limits of what they can do, so every time they ask for it, they can always complete it without danger.

But it is really difficult for some strong people to make a thousand of these shells a day.

The dozens of bullet shells in the basin are the total amount that five people have to polish by hand for more than ten days. Even if the proficiency increases later, each person can do a maximum of three per day, and only a hundred workers can do three hundred.

Is it just for such a small thing to support more than 300 workers?

This is obviously impossible, and no matter how rich Lord Renault is, he is not so bad.

Renault watched from a distance for a while, and saw that the group of people had no good ideas, so he walked up.

"Lord Renault!"

A group of people were about to salute when Renault waved to stop them.

He dislikes red tape the most, and in general, he never asks people to salute.

"How's it going?"

Everyone looked at each other, and finally their eyes fell on Charlotte.

"The kind of gunpowder you mentioned has been made after experiments, but the production of this shell is really not good to increase. ”

Renault picked up a few shells, this copper material with a slight purple-red luster, slightly heavier than the steel one, very smooth to the touch, even the inner wall has been carefully polished.

It's just that this process is really redundant and wasteful for bullets.

Renault also once checked the manufacturing process of bullets through a thousand-degree search, he didn't expect that a small bullet would require so many processes, and those sophisticated automation equipment made him sigh with admiration.

So some time ago, he gave Charlotte the idea and drawings of trying to make a bullet and did not expect to be able to produce it on a large scale soon.

"It's okay, take your time. ”

It is not realistic to make your own rifle in a short period of time, and Renault's plan is the same as when he built a steam engine, just build a barely usable one, and then wait for the app in the phone to automatically upgrade.

He came to the workshop today to see a new ****** -- nitrocellulose made from cotton and nitric acid.

Charlotte opened a sealed box containing a yellowish white crystalline powder, which was the finished nitrocellulose.

"Experimental data. ”

"As you say, there is almost no smoke and residue, but when used on shells, it seems that the pushing force is not as good as black powder. ”

Renault frowned, this is not scientific.

In the history of the previous world, it was this smokeless gunpowder that drove the rapid development of small-caliber guns.

"Show me if there are any finished shells. ”

Charlotte had a grenade with nitrocellulose as a pusher and carefully removed the warhead.

Renault poked his finger at the nitrocellulose that was crushed inside, and immediately knew what the problem was.

The pressure of the medicine is too tight, there is not enough oxygen reaction in it, and the push medicine is not completely burned, and the effect is of course not good.

Do you still need air for gunpowder to burn?

Charlotte heard this theory for the first time, and she couldn't help but be curious.

"Oxygen is needed exactly," Renault said casually, "don't ask me what oxygen is, you don't understand it now." ”

Charlotte couldn't help but be angry.

After becoming Renault's affairs officer, she spent all day in the laboratory, looking at all kinds of books day and night in addition to work.

She had seen enough to be a scholar of erudition, but what made her angry was that no matter how hard she tried, she was always like a child who knew nothing in front of Renault.

Why is that?

She wanted to ask Renault many times, but she had read almost all of Renault's books.

But it's clear that neither the brewing of spirits nor the making of paper, or these techniques of gunpowder, has never been mentioned in a book, so where did Renault come from? )
