After Qin Shuai installed these small devices, he found that Qin Chuan was looking at these things, he felt that Qin Shuai was really hard, but he couldn't help, because these things were really complicated.

Complicated, he felt that none of them had participated in this kind of project, Captain Qin.

In fact, the aliens had already arranged a special formation in the sky that night, but they couldn't attack this protective layer, so they were in a state of immobility now, but they really hoped that Qin Shuai and them would leak out the flaws as soon as possible, because the Beetle-like equipment they placed in the village chief's house was actually something that should be combined.

The village chiefs are now working with their colleagues because of the money, and then sell the materials to the aliens. He only knew that there was a profit in selling these things, but he didn't know where they were really going.

The village chief doesn't know, he only knows that he will give him the money on time, improve the lives of the villagers, hire a good tutor for his son, and let his son live happily, and he really doesn't know the rest.

While the aliens hadn't broken through these protective devices yet, Qin Shuai selected elite soldiers tonight and told them some special things.

In fact, these equipment of his are also following some ancient military techniques, and he preached to them very seriously: "...... Armor protection in ancient military affairs, as early as the emergence of human civilization, some people used animal skins and plant materials to make protective clothing, wearing these protections to protect themselves, resist the attacks of prey and enemies, and reduce damage. …… These protective clothing can be called the earliest armor. ”

He added: "When humans could smelt metal, in order to protect themselves on the battlefield, some people used metal pieces and leather to make armor, relying on the protection of armor to gain an advantage in war. As a result, a professional armor design and production industry and standard armor equipment have gradually developed. ”

He likes to use some entertaining methods, not just to tell these soldiers boring theories, otherwise these people will not listen, they are relatively rude men, so in this factory building while making these small devices and small equipment, and at the same time telling them some important things.

It is said that well-designed and well-made armor can effectively resist the slashing attacks of contemporaneous sharp and cold weapons, protect the vital parts of the wearer, improve the survivability of armored warriors, and thus improve their combat efficiency. Therefore, many countries attach great importance to the production of armor and the development of armor technology.

In this magical factory, some bookcases were also found, as if they wanted to improve the daily knowledge of the workers, but few people looked at them, so these books were very new, and sometimes they were almost not opened, but Qin Shuai asked each of these soldiers to hold a copy in their hands, and probably read it, and then everyone exchanged readings.

The allied soldiers, only then did they realize that they had been talking about devices in this factory very early, and there were things inherited from ancient times, but they were not interested in these people who were here, so they didn't learn, and through this understanding, they knew that starting from the more primitive leather armor, the wise ancients developed different materials and types of armor protection such as metal scale armor and chain mail.

Qin Shuai told them again: "The armor protection in the era of cold weapons has been developed to plate armor, and the plate armor made of steel as a whole has amazing defensive power, but the relative plate armor is also very cumbersome, and most of them can only be equipped by heavy cavalry riding war horses. Heavy armor provides a strong defense for the wearer, but it also places a considerable burden on the wearer,...... Therefore, in ancient warfare, the maximum use of armor was still the heavily armored cavalry, relying on horsepower to carry the weight of armor and provide considerable mobility and terrifying impact. ”

Qin Shuai designed a special kind of cavalry, that is, robot cavalry, and the theories he adopted were inherited from some of the ancient times of the Alliance Army. Heavy armored cavalry is a super cavalry that has the ability to withstand a certain amount of attack, and creates a suppressive breakthrough through the speed and momentum generated by the charge.

He pointed to the models created in these factories and some pictures, which showed the soldiers that the thickness, toughness, strength, and coverage of the armor material had to reach a certain level to ensure that the knight could withstand ordinary slashing and bow killing. Sufficient thickness and area results in a huge amount of weight, which in turn sacrifices maneuverability and flexibility.

Qin Shuai's broad knowledge and his insights ushered in bursts of applause from everyone, which looked very interesting, and some of the little soldiers were eager to try. Qin Shuai arranged for them to make it, and if there was something that couldn't sleep, it could be developed and designed in this factory.

Eager to try, they began to draw with a pen and sketch, and drew what they thought. I didn't expect what I thought to appear on paper, Qin Shuai pointed out some shortcomings, and also praised some of their good points, saying that in the future, they will be gradually developed in this factory, but for the time being, they can't let the villagers in this village know.

Some soldiers were very strange and asked why they couldn't let them know, and Qin Shuai said that he should not be impatient, because this thing has not been completely and thoroughly produced. In fact, some of these soldiers have big mouths, as if they want the whole village to know their great achievements, this is where the weakness of some people lies, so the people used by Qin Shuai are not such people.

These people are like the first batch of people to use, they can only be ordinary soldiers, and like Qin Chuan, they should be senior soldiers in his barracks, because they are brave and resourceful and love the people, this kind of original starting point is right, and those who like to show off their great achievements may not necessarily get too much in the end.

After arranging these Qin Shuai actually said that he was very sleepy, he went back to sleep in his own room, and went to sleep on the floor, everyone didn't want to disturb him when they saw Qin Shuai sleeping in a sleeping bag, so they started to make their favorite models at these stations he arranged.

Qin Chuan took turns to look around, and felt that there was nothing special, so he went to rest. This factory actually has a special equipment, it is their walls, which are not made with the kind of thing that builds houses, but with special materials, so Qin Shuai couldn't wait to rent this place, the rent is not cheap, but it is useful.
