At the same time, Shu Han combined these 800 soldiers together and organized them into a personal guard force, one is to have good contact with them, so that they can quickly integrate into the atmosphere of Joaquin City, and the other point is that they are wild and untamable, and it is relatively difficult to be with the troops of Joaquin City, and some physical conflicts often break out, which is not beneficial to training and the unity of the army.

Another point is that these people's bodies are really strong, general military training for them, there is no problem at all, their physical fitness is so strong, if they just crawl around in traditional training, it is really a waste, so Shu Han hopes that they can be reorganized, and then receive more rigorous training, in Shu Han's mind, these people are undoubtedly the future Skywalker reserve personnel and good seedlings of special forces.

Their physical fitness is very strong, far better than the people in these cities, and at the same time surviving in the forest, which makes them very flexible, and they are also good at surviving in no man's land, this kind of experience and physical fitness, for a soldier, has an absolute advantage, Shu Han naturally hopes to use this to make this army stronger.

Therefore, Shu Han gathered them together for special training, and then eliminated some unqualified people from them, and sent those people into the ordinary army, leaving a total of five hundred people, and then set up a special operations brigade, under the direct command of Yang Yi, as a Skywalker, since coming to Joaquin City, Yang Yi is engaged in the management of the family business, for the military, Shu Han did not let him touch, after all, as the eldest son and grandson of Yang Wang Di's family, Shu Han was not so able to trust him at the beginning, However, after such a long time together, everyone is not very old, although they are precocious, but they are far faster than ordinary people.

Through communication, Shu Han knew that Yang Yi was a good boy, although he was a little unruly on weekdays, his attitude towards things was also like and dislike, and his speech was also very upright, which was very unpleasant, after all, his thinking was too simple, and the discussion of the problem was also in a very shallow state, in this case, the view of things itself is relatively shallow, coupled with his personality is too straightforward, he will always feel that what he says and thinks is right, so he is relatively not easy to contact.

In addition, he was born in a famous family, and he has such a disrespectful attitude in his bones, and the same is true when he first started to communicate with Shu Han, thinking that Shu Han is just a slave, why should he care about his own affairs, this situation happens from time to time, but Yang Yi is undoubtedly a good child in nature, although he was a little disobedient at the beginning, but after seeing Shu Han's ability, he became very obedient, and after his father's death, his personality has also changed a little, and he is no longer as free as before, also began to know how to get along with people, but the personality is still very upright, which is why the two of them can become friends.

His ability is undoubtedly very powerful, after all, as the heir of the second family of Black Iron City, he must have basic skills, and he has received the most rigorous training since he was a child, and this has become his instinct for combat, and this special forces unit is handed over to him, Shu Han believes that he will be able to train it.

And Yang Yi has long been tired of those administrative things to operate, compared to sitting in the office and pointing fingers at things outside, he still prefers to lead the army to charge outside, and now Shu Han's order is obviously as he wishes, and he is happy to take over the army.

And his character, commanding this army is indeed the most suitable, these tribesmen and village people, they themselves have no scheming, they yearn for strong power, and ordinary people really can't control them, after all, they survive in the wild, relying on their own strength, so if you want to lead them, you must show much stronger strength than them, and Yang Yi obviously has such strength, and there are two Skywalkers in this team, who were born in the tribe.

These two Skywalkers applied to fight against Yang Yi when Yang Yi was transferred for the first time, obviously deep down they were dissatisfied with these managers of Black Iron City, in their opinion, the two of them were strong and should be the managers of this army, how could they suddenly parachute in a person to manage them?

And Yang Yi let the two of them go together, and in ten minutes, completely defeated these two people, these men undoubtedly believe in strength, when they saw two Skywalkers against Yang Yi, they lost in less than ten minutes, they were full of worship for Yang Yi, and they were obedient to his orders, and then Yang Yi summed up a set of training methods based on his own experience, under his training, this army was quickly reborn, and its strength was greatly improved, even these soldiers themselves could feel it, Under the leadership of Yang Yi, his own strength has been greatly improved, so he has more trust in Yang Yi, and in no more than a month, Yang Yi completely conquered this army.

This is Yang Yi's strength, and it also allows Shu Han to rest assured of him, and this force does make Shu Han very satisfied in terms of combat effectiveness, especially in the forest, in the subsequent forest search, this force through its own familiarity with the forest, as well as the prediction of danger, successfully let the troops avoid several dangers, and found so many tribes in the deep mountains, and found almost a thousand people, of which 200 were absorbed into the army by Shu Han, and 150 people entered Yang Yi's troops.

This special brigade has reached 650 people, and for this force, Shu Han undoubtedly attaches great importance to it, not only with three Skywalker leaders, but also with the most advanced weapons, after the machine tool was invented, the people of Black Iron City are obviously not satisfied with these weapons of the early industrial age, they are eager for more advanced weapons.

And those production drawings themselves are there, how can they not produce, of course, those big guys can't produce Black Iron City in a short time, but it is relatively easy to transform the guns, and now the weapons used by Black Iron City, the Holy Alliance and Guangyuan Kingdom are still similar to weapons such as lying guns, that is, the kind of gunpowder that is loaded with gunpowder, and then fired with a shot, and then reloaded again, a skilled musketeer, it takes about a minute or so to fire a bullet, and the speed is very slow, And the distance is also very close, almost no different from the archers.

And some of the more top can use some gunpowder and warhead integrated bullets, which is very similar to modern bullets, so that only one bullet needs to be loaded at a time, and the loading speed will be greatly improved, but this kind of bullet, in the original background of the times, is really very difficult, a skilled worker to make such a bullet, it takes more than an hour, and there is a danger of explosion, so the production volume of Black Iron City is only four or five hundred rounds per month, Only the most elite guards, or nobles, can be equipped, and it is absolutely impossible for ordinary people.

And with the advent of machine tools has been a variety of steel raw materials discovered, which makes the possibility of manufacturing bullets has been greatly improved, before the Black Iron City has organized all kinds of industrial experts to discuss, and finally designed a new industrial line, can really incorporate the production of bullets into the scope of the industrial system, today's Black Iron City, the production of copper shell bullets has reached the extent that there can be 70,000 per month, although compared with modern times are still a lot behind, but this is already a huge progress, and this number is still expanding every year.

Because when four or five hundred rounds were produced every month, the number of workers was more than 100, of which there were about 30 real craftsmen, and about 70 apprentices, but now, only 60 people are needed on a production line to complete the task of 70,000 rounds of ammunition a month, which makes Black Iron City's desire for investment much greater, and in the next two years, Black Iron City intends to make the production of copper shell bullets reach about 300,000 rounds per month, so that it can really deal with the war, At the same time, it also allows all armies in the entire Black Iron City to use this type of weapon.

And with the manufacture of copper-shelled bullets, the transformation of firearms has become a key, the previous rifle, are from the front of the barrel into the gunpowder and bullets and then fired, this speed and efficiency is obviously very poor, in modern times most of the bullets have been placed in a magazine for shooting, there is a spring installed inside, can automatically replenish ammunition, now automatic filling this is obviously not possible, but equipped with a magazine, and then use the telescopic device, the bullet is pushed into the trajectory, It's not hard to do.

In this way, it can be done, and the bolt can be fired at the point where it can be fired, which is a bit like a weapon in an anti-Japanese TV series, this kind of weapon is relatively speaking, and the combat efficiency will be much greater, and this is also a project that Shu Han mainly supports now, and these guns, the first batch of troops equipped with them are special forces and Shu Han's own personal guards.

Of course, if he could, Shu Han certainly hoped that this kind of firearm could equip the entire army, but obviously it was impossible in the short term, and the production of bullets could not withstand such bullet consumption, in addition, the parts of this type of firearm would be more complex than others, and it would be more difficult to manufacture, and it would take a while for him to be able to industrialize and manufacture, and he would only be able to equip some elite troops at first.

As long as this kind of firearm is successfully developed, its change to the battlefield will be huge, think about others still need more than a minute to fill gunpowder and bullets, and you only need to pull the bolt to directly fill the bullet, it does not take three seconds, this progress, it means that others fire a bullet time, you can fire thirty bullets in a row, its destructive power is naturally self-evident.

In addition, Shu Han is also developing machine guns, this weapon in the First World War, but completely changed the pattern of war, can be called a peak combat ability in the era of chemical weapons, as long as there is a machine gun on a road, it is difficult for thousands of troops to want to pass, this kind of combat weapon, if really developed, will completely change the balance on the battlefield today, so that Black Iron City undoubtedly won the victory of the war.

But again, it is very difficult to develop such a weapon, the most important of which is that the requirements for steel are very high, and the gunpowder in the bullet will burst out with great power during the firing of the bullet, which is not only with great force, but also with huge heat.

Like the steel used in ordinary rifles, it can fully withstand the heat generated by this force and gunpowder, because the frequency of his fire is quite low, often only a few seconds to fire, a rifle can withstand it, but extremely strong is not.

In modern times, a machine gun can often fire more than 2,000 rounds of bullets in a minute, or even more, like a type of automatic machine gun installed on a warship, often can pour tens of thousands of bullets in a minute, ordinary steel is simply not supported, it only takes a few seconds, it will cause the barrel to explode because of the excessive heat, and it is impossible to use at all, which is also the biggest problem of today's machine guns.

It is not difficult to make machine guns, the drawings are right in front of you, but the key is that if the steel is not up to par, then these machine guns are manufactured, and the scope of their use will be very large, basically they will crack in less than a few days of use, so it is a very important problem to invent better steel.

In the library of the Black Iron City, there are actually a lot of steel formulas, but the raw materials in these formulas, the Black Iron City can not be used locally, because the surrounding area is not at all, the only way is to invent new formulas, to create in the original era, relatively rare steel, only in this way, can you make machine guns, or go to other places to find, but in this case, the unknown possibility is too great, after all, the north can no longer continue, it is difficult to go west, the east is the sea, only the south can go, But that's already a big mountain.

In addition, the consumption rate of machine guns for bullets is amazing, ordinary rifles have 100 rounds of ammunition a day, at most 200 rounds of ammunition, but a machine gun, if you want to work for a day, at least 20,000 rounds of ammunition are needed, with the production and manufacturing speed of Black Iron City today, it is obviously far from enough, so the manufacture of machine guns is undoubtedly difficult, but Shu Han did not give up, after all, in this time without oil, machine guns will be the most critical part of the battle, who can develop machine guns, Whoever can influence the situation of the war in advance, such an important weapon, how could Shu Han give up.
