In fact, Qin Shuai deliberately arranged it this way, just so that these soldiers could look through some books in the bookcases in the factory building when they couldn't sleep, which was actually very useful for them in increasing their knowledge.

These soldiers were reluctant to learn because they were pampered before, but once they were quiet, after being devastated and tortured before, after they had peace and freedom, they still liked to learn things, and when they had time, they looked through these books.

Among them is a story about the heavily armored cavalry of Western Europe, which attracted the attention of several soldiers. …… The heavily armored cavalry of the Middle Ages, with strong armor, was clearly not conducive to hand-to-hand combat, and was largely confined to the front. This mode of manufacture reflects the way heavily armored cavalry is used on the battlefield – charge, turn around, and charge again. …… Knights dressed in chain mail or plate chain composite armor rely on sophisticated equipment and high martial arts to crisscross the battlefield, sweeping away the infantry in a crushing posture. When you see the heavily armored knights running towards you like a landslide with their guards, the weak-willed soldiers will immediately abandon their armor and flee in all directions.

Over time, advances in science and technology led to rapid advances in armor technology, and the heavy plate armor of the time could withstand even the early musket fire. With the discovery of hot weapons, the defensive ability of metal armor was gradually insufficient to resist the firepower of hot weapons, so it gradually withdrew from the stage of history.

Several people liked the book so much that they took turns looking at each other, and then turned to a book about the ancient times before the Union Army. One of them is the heavy cavalry of the ancient times before the Confederate Army...... Not only are men armoured, but even war horses are fully draped, and a cavalry is like a tall statue of the god of war, and when they advance, it is like a steel wall pressing against them...... When the ancient army besieged a fortified fortress, it had to collect wood on the spot to build various siege equipment, and use the various functions of the equipment to resist the fortification and city defense advantages of the fire defender.

However, wooden equipment is very easy to be the target of the defender's fire. Therefore, the craftsmen of the army covered the sun-dried raw cowhide on the equipment, which was tough and fire-resistant, and could effectively defend against the enemy's arrows and fires, improving the survivability of siege equipment, which was also the main role of armor protection.

A little soldier suddenly remembered something, and said: "I remember that Sergeant Qin made some special devices for us, not only did he use them on robots, I remember that he used to play some devices on the electronic display screen, but I don't know where he put them, I really want him to find out, but now that he has gone to sleep, I really can't bear to disturb him." ”

Qin Chuan listened to the whispers here, after all, he was born as a young master, and he couldn't sleep well here, so he got up and participated in their discussion.

Listen to these soldiers talk about armor in modern military affairs. "With the rapid development of productivity, the output of the metal smelting and forging industry has also soared, so the armor protection has also developed rapidly...... In order to resist the rapid development of hot weapons, metal armor sacrifices protection area in exchange for better protection against vital ......"

But a few older soldiers sighed and said that some good armor and equipment are actually prepared for those non-commissioned officers who have made outstanding achievements, and it is already good for them to get ordinary weapons, at most they can only protect themselves, if they want to attack the enemy to a greater extent, they have to ask the above, so I don't know what will happen when Qin Shuai leads the troops to fight, although Qin Shuai has escaped the alien attack with them these times, but they have not launched a large-scale attack, so they are still observing.

Qin Chuan asked them to make persistent efforts, not to be discouraged because of these things, because he believed that Qin Shuai would definitely lead them to make good progress, since he had dodged the attacks of the aliens again and again, the key was that he had a certain strength, he was very smart, and he would definitely have the power to attack, but he hadn't arranged the layout yet, and he didn't want to cause everyone's casualties, so he would think about it more. When these soldiers heard Qin Chuan say this, they became more steady.

They each discussed these stories about the armored soldiers before for a while, and then they went back to sleep, Qin Chuan couldn't sleep tonight anyway, he didn't know what he ate tonight, thinking about the food he ate tonight, it seemed that he drank a cup similar to coffee today, but it was a drink, and it wasn't the taste of coffee, but the color was very similar to coffee.

Qin Chuan remembered that it was handed to him by a small soldier, this little soldier was a very loyal and reliable person in the alliance army, so he drank it without hesitation, but the others also drank it, but they drank less, Qin Chuan liked this taste very much, so he drank a few more glasses than others.

He couldn't sleep, so he simply read all these books, and went to the workstation to see the model made by Qin Shuai, and made one himself, but he became more and more excited, and then walked to the window and looked at the stars outside, and after a while, suddenly a person patted him on the shoulder, and when he looked back, it turned out to be Qin Shuai.

Qin Chuan asked, "Did I wake you up by walking back and forth in this room just now?" ”

Qin Shuai said: "I just woke up, I just saw the model you made at the workstation, is it modeled after me?" But there are some materials in it that you haven't put in yet, although these materials are as thin as cicada wings, the effect of putting them in is completely different, and after amplification, these thin materials like cicada wings will become very strong and durable, so I will help you put them on. ”

Qin Chuan said: "Don't use it first, I'm just curious why you have developed and designed so many ingenious things, why those old designers of our alliance army can't do it, they don't even have this concept, but you can think about things in a few decades, or even a hundred years, and the layout is quite reasonable, I don't just want to learn from you, to a large extent, it's a curiosity, I feel as if you have something hidden in the dark." ”

Qin Shuai let out a hearty laugh, saying that Qin Chuan must have been too worried, he called Jiang Linda when he woke up just now, but no one answered there, so he reacted, it was not yet morning time, it was still night.

Now the two of them can just have a few drinks, because tea instead of wine is also a good choice. He was holding a tea caddy, which had been given to him by the village chief.
