This is an industrial park, and the machinery in it is very complete from ordinary drilling machines to millions of five-axis machining centers.

Of course, although Zhang Zhen is a universal worker, he is only a universal worker who manually operates machinery, in addition to turning, milling, grinding, inserting and pulling drills, he will be able to do simple CNC programming, but he is not proficient, the programming of this machining center is more troublesome, and he must learn from scratch, which is very much needed to be made up.

The women studied seriously and made fast progress, and Zhang Zhen began to familiarize them with all kinds of machinery.

In this machinery industry alone, compared with men, women are at an absolute disadvantage, whether it is the number of people or salary, the proportion of employees is afraid that it is less than ten to one, but in some aspects, the talent of girls themselves, but men can not compare.

For example, argon arc welding, women's delicate minds and more uniform breath, if it is a gentle girl with a personality like water to do this, it is easy to become a master of argon arc welding, just the ratio of less than ten to one, the gender ratio of the most powerful argon arc welder is five or five, this is not comparable at all, not convinced.

And the instrument lathe, it must be a female worker.

The small bed Zhang Zhen can hook a finger of the tool holder supporting plate flew back, this instrument lathe, Zhang Zhen has been working for so many years and has worked a total of two days, don't look at the small workpiece of the machine tool, but Zhang Zhen is tired enough, and when the female lathe comes back, Zhang Zhen feels free from the sea of suffering.

Zhang Zhen is the same hand-in-hand professor, the girls are familiar with all kinds of machinery one after another, and look at their performance, note who is suitable for which, and carry out simple assembly line operations in the future, after all, the fine division of labor of the assembly line is the best way to ensure quality.

The industrial park is as warm as spring, like a huge constant temperature workshop, and the outside world is cold and life-threatening.

It is a famine for many years, and for the victims, it is best to survive the spring and autumn days, and it is easy to find food on the way to escape the famine.

The summer with severe drought became even hotter, unable to walk at all, and prone to disease and plague, and a considerable number of the victims died in the middle of summer.

And the hardest part, that's winter.

Everything withers, ice and snow cover the earth, even the grass roots are difficult to dig, and one by one is not clothed, the hungry body can't bear the cold at all, many people are either starving to death or freezing to death, and they can't survive the New Year.

It was three days after Zhang Zhen measured the temperature outside, two consecutive nights of heavy snow, the sky and the earth were white, and on the field, many people who were faltering, and some dragged their families, once they fell, they could no longer get up.

Zhang Zhen commanded, Xia Zhongyong and his wife quickly found more than ten women, brushed the cauldron in the courtyard and poured underwater rice, Xia Zhongyong and Zhang Huanghe went to build a shed outside the village, ready to give porridge to help the people.

According to Yang Hanlin, this porridge is too thin and too thick, it is not good, it is too thin because of its own bad reputation, it is too thick and easy for the victims to stay, and it will gather more and more, and the owner of the family business can also eat the poor.

To put it simply, if they don't starve, they can be sent away.

Although Zhang Zhen's kindness was overflowing at this time, he also wanted to send the passing victims away as soon as possible, if nothing else, he was afraid that after the victims stopped, they would harm the wheat seedlings covered in the snow.

That's a hybrid wheat from later generations, the only excellent variety in the world, and I don't know how many years it will take to breed it.

Human life is not as good as crops, it sounds very cruel, this saving a few people for a while and saving the world for a lifetime, just like killing a person or a few people in the future, there are many times, we need to carry moral beliefs or something, whether we are kidnapped by morality or not, we have to make trade-offs.

In the end, Zhang Zhen still chose Yang Hanlin's proposal, but the rice porridge was slightly thicker, and in addition, each person was given one or two pieces of steamed buns, after all, these are all human lives, and they can't get over it on their conscience.

A bowl of porridge, a small piece of steamed buns, these must not be enough, even if it is a child.

The victims also cried and begged for more, but Zhang Zhen returned to the compound, Xia Zhongyong and Zhang Huanghe were firmly carrying out the orders of the lord, and they didn't give more, which was called an iron-faced selflessness.

The tenants had the silver given by Zhang Zhen, and the coarse grain had already been prepared at home, ready for the winter, and when they saw the continuous flow of victims, they immediately panicked, and they were even more nervous about their harvest.

More than 80 men gathered together, and in total, they were worried every day for fear that the wheat seedlings would be eaten, which was not a thing, and it was more reassuring to take turns guarding the fields.

After discussing, he took the initiative to find Zhang Zhen to borrow a workshop by the lake to live temporarily, anyway, there were not a few craftsmen, and he was idle after it was built, and now the research and development are in the industrial park, Zhang Zhen borrowed it very happily, and rented a partial house in the first family in the village, so that they could watch it at both ends, and prepared two gongs to facilitate communication to ensure that nothing goes wrong.

Other than that, there was nothing major outside, and Zhang Zhen spent the winter training apprentices in the industrial park, researching firearms, and incidentally equipping a forklift and a forklift with armor.

Speaking of this firearm alone, a modern rifle and pistol is impossible in the short term, a single metal cartridge case can give Zhang Zhen a headache, it is easy to make, but it is difficult to mass-produce.

The arquebus didn't even have to think about it, and was directly eliminated by him.

Then there are flintlock pistols and firing pistols, which are more realistic than flintlock pistols.

In fact, the starting gun is already a modern firearm, as a later generation, Zhang Zhen is more than 300 years ahead of the knowledge, it is not how to improve how to improve, as long as you think it is useful, add it.

The first is the bayonet, equipped with this thing, there is also the power to fight back in close combat, otherwise a musket without ammunition, in the face of a broadsword and spear, I am afraid that it is not as good as an ordinary burning stick.

The second is the front sight, the Ming bird system is limited by the processing technology, after firing is just the right direction, I don't know where to hit, I use the machine tool to fine boring the barrel, not to say where to hit, that is also 8 nine is not far from ten, how to do without a crosshair?

The third is also very important, that is, the cone-shaped buckshot, the spherical egg-shaped one is blunt, how can it be more penetrating than the cone-shaped pointed one?

For Zhang Zhen, the most important thing is to reload.

The Ming Dynasty's bird system, it would be good to be able to load twice a minute, or to reload in front, first enter the fire rope, and then pour in the gunpowder, and then stuff the lead bullet in, and then use the whole strip to compact, this series of actions down, not to mention the trouble, but also must stand and load, this is a live target on the battlefield!

This ammunition is also improved in two aspects, one of which is definitely a fixed paper shell bullet, which cannot be made into a metal shell, and the paper shell is still relatively easy, and it is only necessary to put the primer gunpowder warhead into the paper shell in turn and wrap it.

The second is the firing pin rear loading, compared with the front loading, the biggest drawback of the rear loading is the sealing, the simple mechanical seal, subject to cold and heat changes and wear or something, once the gap is large, that is to watch the fireworks up close, waiting to spray a face of gunpowder.

At this time, there was no rubber, but fortunately, many of the machines produced by several machinery factories in the industrial park needed to be sealed, and some of the sealing rings were in stock, enough for Zhang Zhen to assemble tens of thousands of guns.

After two months of continuous experimentation and improvement, Zhang Zhen finally completed the production of the first self-designed firing pin gun according to the memory of later generations.
