Abu had been involved in target shooting before at school and after work, after all, even as a medical security worker, this kind of practice was essential. But at that time, it was someone else who set up the field in advance and pressed all the bullets into the *.

When you arrive at the shooting area, put on *, and when you hear the order to shoot, you just need to load and aim.

But now, all the implementation plans and all the guidance and demonstrations need to be done by themselves, which involves details such as targeting, targeting, vigilance, setting up a gun carriage, etc., the coordination of each link, the risk assessment and solutions of each step, all need to be studied in depth.

And Abu himself does not know much about these, can only improve and perfect step by step according to the impression in his memory, as the saying goes, slow work makes meticulous work, as long as you ponder the past little by little, it will always produce better results.

In the development of muskets, he adopted a plan of leapfrogging development, directly using a rifled structure, overcoming the problem of low accuracy of smoothbore guns, and at the same time adopting the method of rear loading to improve the firing speed.

At the same time, to lay the foundation for the next step of the improvement of semi-automatic and automatic rifles, he directly imitated the classic "Hanyang made" in later generations, which is commonly known as the "old sleeve".

This directly avoided a lot of detours, after all, the history of the development of muskets in later generations gave him great help and route guidance, the advantages and disadvantages of guns largely lie in the quality of the barrel, as long as the quality of the barrel is guaranteed, there will be no great danger.

At present, this musket is still the simplest non-automatic rifle, after a shot, it must be manually unshelled, and then reloaded, the advantage is that the structure is simple enough, mainly to verify the quality of the barrel and bullet.

The manufacture of bullets was more troublesome, because the demand for copper was relatively large, so Abu asked Liu Yuanlu to collect copper coins, melt them and purify them to make copper. In the manufacturing process, Liu Yuanlu shouted vigorously, what is this thing you are studying, this is a living money-burning! After all, the coins of this era were made directly from copper.

But when he saw the enormous power of Abu's first test shot of the musket, he stopped talking about it, and concentrated on how to get more copper.

If they can produce more bullets, then their force value and self-protection ability will develop rapidly, and Liu Yuanlu also understands this very well.

In fact, before they studied the musket, the development of * had made great progress, and with the most basic raw materials such as nitrocellulose, alcohol, and glycerin, all that remained was the configuration ratio of various raw materials.

Abu has a lot of successful experience and bloody lessons of later generations to guide him, and directly avoided many detours and forks in the road. In addition, he is meticulous and considers the risks before each experiment and test, and at the same time formulates specific preventive measures. This makes the development of this epoch-making product have been carried out calmly and smoothly.

After they have * and need to be tested, they usually leave the valley and do it directly on the narrow mountain road into the valley, which can both test the * and pave the way for access and exit.

The road leading to the outside of the valley was rugged and difficult to navigate, and it was a natural barrier for the people in the valley.

However, with the expansion of foreign trade and the increase of resources, this mountain road has become a bottleneck restricting the communication between the valley and the outside world, and many materials can only be piled up behind the Abu Hotel in mountains and cannot be transported back in time.

Therefore, taking the opportunity of the power of the experiment, just open up this road, what needs to be paid attention to is the problem of *dose, in case of carelessness, blow up the mountains on both sides of the road, it will be worth the loss.

Abu has been made a backer by the saint, which means that the entire Queergeda Mountain is his, and he can deal with it as he wants, and the Tianshan Mountain behind the Barren Mountain is also a borderless land, so even if he is all encircled, it is estimated that no one will care about him.

His purpose was to minimize the risk of outsiders discovering the valley before he had enough self-protection ability, so he tried to pay tribute and obtain the ownership of the barren mountain.

At the same time, he set up several rounds of secret sentinels at the mouth of the valley to be responsible for guarding. Although in this place where birds don't poop, the chances of someone breaking into the valley are slim, be careful.

Although he did not have the help of the stone crusher of later generations, Abu still had the stones and clay crushed as much as possible, and transported some of the large piles of asphalt, melted it and poured on it, which became the first asphalt road today. The big guys were really excited about this solid and smooth road for a while, and then they spontaneously leveled the road surface in and around the residential area and poured asphalt, which greatly improved the living environment.

Now that the development of the musket has been basically successful, all that remains is to increase production and automatic shell extraction.

If the automatic shell removal and bullet automatic loading device are realized, it will have a qualitative leap in the lethality of the musket.

In the next few days, Abu gathered the young people together and explained the principles and development of firearms, and by the way, he told everyone about the future prospects. Hearing this, the young men's eyes lit up green, staring at Abu like wolves, and they all asked when they would be able to use such firearms.

Abu could only smile bitterly, this is an era that requires patience. These young people are waiting for weapons, and the development of weapons is waiting for the mood of a certain person; And once these young people are equipped with these weapons, they also have the strength to threaten this person, which is really ironic when you think about it.

In the future training, in addition to the daily physical fitness and cultural classes, shooting training was also added every now and then. Although there were only a few guns, as the production of bullets gradually increased, the number of bullets that everyone could shoot when shooting also increased. Empty bullet casings are carefully picked up and remanufactured.

What Abu has to wait now for is whether the free chairs and super cars dedicated to Chang'an City can make new contributions, and if all goes well, the construction of branches and the mining of manganese ore can be accelerated across the country.

On this day, at Lao Yangtou's house, Abu looked at the thin piece of paper in his hand over and over again, admiring.

The old Yang Tou next to him looked at Mr. Abu's expression, and poured a big sip of wine.

He lived up to his expectations and successfully completed the task assigned by him, using cotton and a kind of vine fiber born from rock climbing in the valley, and adding some silk silk, he successfully made this super tough paper.

After the heavy object is pressed, the paper is ultra-thin, but the toughness is excellent, it is difficult to tear, put it into the water and then take it out, as long as you shake it, it will dry immediately, which fully reflects the characteristics of not soaking in water.

Abu bowed to Old Yang's head and said with a smile: "Thank you, Uncle Yang, you have made a great contribution to our valley again." ”

Old Yang Tou didn't expect Abu to say this, and he would have such a high opinion of the paper he made, so he hurriedly said, "Sir, this is unacceptable." ”

"Make, make, I can print money right away, haha." He came out of Lao Yangtou's place, and walked directly to the direction of the classroom to find Fang Huanting.

Just in time for the end of class, the students were happily playing and resting, and when they saw Abu coming, they stopped to salute and say hello, and Abu smiled and returned the salute.

Fang Huanting was chatting with Meng Lu, with the graduation of the older generation of students, most of these new generations were assigned out to go their separate ways, mainly in charge of work in hotel branches in various places, and some were directly called into the special selection team to ensure the safety and vigilance of the valley. In order to take care of her elderly mother, she chose to stay in school and became a teacher, and now she has a marriage contract with Zhang Caier's brother Zhang Liang, and it is expected that the two families will discuss marriage matters at the end of the year.

Seeing them, Abu greeted the two women with a smile, and Meng Lu saw that Abu might have something to talk about when she looked for Huanting, so she said goodbye to the two after returning the salute.

Although Fang Huanting has been a wife for a long time, and is already the mother of two children, a boy and a girl, her straightforward temperament has not changed, and when she saw Abu looking for him, she asked with a smile: "Mr. Abu, what is the big thing that you need to arrange in person?" ”
