First of all, the molten iron was steel, Yang Wenli arranged for eight slave soldiers to carry the molten iron ladle, pour it into the mold, and when the molten iron turned from liquid to solid, he ordered loudly: "Turntable"

The twelve slave soldiers on the squeezing table, shouting the trumpet, worked hard together, pushed the lever, and spun like a grinder.

At first, it was very easy, when the punch at the top of the screw was covered on the red-hot barrel, it was immediately blocked, and everyone exerted their strength in unison...... Three, one, two...... Three ......"

I saw the punch sink little by little, and under the action of huge force, the hot extrusion table made a creaking sound.

It wasn't until everyone couldn't push anymore that Yang Wenli said loudly: "Back to the plate"

With a crisp metallic sound, the punch lifted, revealing the jet-black color of the barrel, and the burrs that had been squeezed out by the force because it was not precise enough, and the hot steel was squeezed by the force, like mud, emerging from the gap between the punch and the barrel mold.

The screw of "taking the inner mold" was returned to the top, and Yang Wenli ordered loudly again.

Because of the huge squeezing force, the inner mold is solid, the barrel of the 60 mortar is 80 centimeters long, the inner mold must be longer, one meter long, and it is a round steel column with a diameter of 60 millimeters, which has hundreds of catties.

"One-two...... Three, one, two...... Three ......"

Due to the reason of heat expansion and cold contraction, the barrel shrinkage and clamped the inner mold, and several people still used the lever principle to pry and take out the inner mold little by little.

When the inner mold was taken out, Yang Wenli ordered the slave soldiers who had already prepared it: "Pour water"

This water is not ordinary water, but the best white plaster mud rare earth solution experimented some time ago, which can not only accelerate the cooling rate of the inner wall of the barrel and make the barrel more compact, but also dope the inner wall of the barrel to form a layer of heat-resistant and oxidation-resistant alloy.

"It's okay, it will take a while for the barrel to cool down, let's clean it up, and then cast the screw, firing pin, and base." Yang Wenli made the next arrangement.

The casting is very hot, everyone is shirtless and sweating, everyone doesn't care about 3721 first, pour it two catties of water, this point, even Yang Wenli and Wang Rucheng are no exception.

"Great Commander, this hot extrusion process does have miraculous effects, it is much denser than the blacksmith knocking with a hammer, and the self-tightening process of the gun body you said, the doping of the gun chamber, is not simple, far from what today's craftsmen can imagine." At the moment of leisure, Wang Rucheng sighed with emotion.

"The principle is very simple to say, the difficulty lies in the scientific researchers, can they think that without the experience of their predecessors, according to the world today, Europe, the fastest development of science and technology, it will take at least a few hundred years to cast this simple mortar.

O Ru Cheng! Science and technology are endless, which requires us to constantly use our brains, to study the latest science and technology, but also to cultivate reserve scientific research talents, this is the greatest cause, worthy of our lifelong struggle, which is much more beneficial than learning from Confucius. ”

Yang Wenli digressed from topic, and ruthlessly criticized Master Confucius.

Wang Rucheng has long been accustomed to Yang Wenli's character, and he doesn't bother to refute it now, just listen.

Casting screws and firing pins, firstly, are small in quantity and neither is large in size, and secondly, both are only extruded with a small mechanical extruder, so it is not long before both are cast.

"Ru Cheng, the next thing is to polish and tap, you have done all these things, you go and tell them how to do it, and I will control it on the side.

We will have more and more scientific research tasks in the future, and you will slowly learn to control the overall situation, and I must find time to develop other weapons and equipment. Yang Wenli wants to slowly cultivate Wang Rucheng's overall ability, like the chief engineer and software architect of later generations, he can liberate himself from the bottom.

"Whoa! Rest assured, Commander, I can do these simple things. Wang Rucheng patted his head and reassured.

A busy and boring day has passed, and this has become Yang Wenli's daily routine.

Working in the foundry workshop in the workshop, it is very hot, I don't know how much sweat I have to sweat a day, and the workshop is hot and there is a large pool, no need to boil water, everyone takes off their clothes and takes a bath by the pool.

Only Wang Rucheng didn't dare to wash with everyone, not that he was a woman or anything, but that he was relatively thin, and he washed with a tall and strong man like Yang Wenli, and he was more inferior.

The production of nitroglycerin requires a lot of oil, and there is no pancreas to buy on Changsheng Island, Yang Wenli simply uses a small amount of soda ash for making glass to make caustic soda, and then adds sulfur to react with the grease to make sulfur soap, so that the bath can be washed clean.

He took a few bars of soap home, and also got a few fragrant kisses from Xiaoyan'er, which was an unexpected joy.

Due to the small amount of soda ash, only senior officers are currently allocated, with the exception of the workshop, and the slave soldiers and Liao civilians can enjoy this preferential treatment, which also makes the workers pay more attention to personal hygiene, even female workers.

It should be particularly mentioned that in addition to Yang Wenli's slave soldiers and Wang Rucheng's several traitor assistants, there were only civilians and no slaves in the workshop.

The reason is that there is a salary for working in the workshop, and civilians are given priority, and the second is that there is an explosives workshop in the workshop, which is very dangerous, and it is also necessary to prevent those Tartar slaves from holding grudges and repaying their submission, so slaves are forbidden to enter the workshop.

Since the conquest of Jinfu Erzhou and Yongning, there are now thousands of civilians on Changsheng Island, including Han maidservants who are married to women, who can work in explosives workshops, and those Liao civilians who go to the foundry workshop to do some heavy physical work.

Yang Wenli has been taken in as a leader, then Yang Wenli is obliged to find a way for them to survive, these civilians working in the factory are already pure workers, they have no land, and they need to use the income from their work to support themselves and their families.

They are different from the dozens of shipowner families who came to Liaodong with the Black Armor Army, the shipowners have land, this is Yang Wenli's reward for their merits, and it will be difficult for civilians in the future to have land, unless they have made outstanding contributions to the Black Armor Army.

This is the result of Yang Wenli's policy of stipulating that only soldiers own land, so what about these civilians? They can only be converted into workers, merchants, craftsmen, hawkers, etc.

This is also a huge task for Yang Wenli, for which he and several chief officers of the logistics department have held several temporary meetings to discuss countermeasures.

Yang Wenli has a general premise, that is, no matter who he is, he must ensure that the people under his rule can eat enough, which is a very difficult task in the troubled times of the late Ming Dynasty, and it is almost as difficult as the goal of requiring the people to be well-off in later generations.

What is the significance of his general premise? That is, no matter who does the work or not, he can go to the logistics department to pay food on credit, if the logistics department does not arrange work for him for a long time, then he can continue to owe on credit, such as some people who have lost labor, then he is equivalent to receiving relief food.

Yang Wenli left the task to the logistics department and left it alone, and asked several chief officers of the logistics department to find a way to solve it.

From here, there was a significant difference between Yang Wenli and other regimes, for example, the Ming Dynasty only asked the people to collect taxes, regardless of the life and death of the people, so the tragic phenomenon of cannibalism appeared at the end of the Ming Dynasty.
