The wind howled.

It blows from the north to the south, carrying a sharp breath, sweeping across the land of China. Just like Fei Qian's every move, it has changed many features of China.

The Han Dynasty lasted for three to four hundred years, but in fact, the research on armor in the Han Dynasty did not make much progress, at least compared to the Spring and Autumn Period and the Warring States Period. It was like the models of fruit machines with S and without S in later generations. No details. You can't see any significant changes at all.

Because from the Spring and Autumn Period to the Warring States, and all the way to the Han Dynasty, China was actually technologically ahead of the surrounding nomadic peoples, as well as the surrounding foreign states. Therefore, even though the Han Dynasty fought several rounds with the Xiongnu, Xianbei, Xiqiang and Baiyue, there was no improvement in armor. The demand is not big.

Technology has been suppressed, and naturally it lacks some driving force. It is like a monopoly that will refuse updates to new technologies in the end and try to fool them by changing their shells.

The person who blew a fresh and biting cold wind into the development of Han Dynasty technology, especially weapons and armor technology, was the "prodigal son" Fei Qian.

The Han Dynasty was the first dynasty to prove the existence of complete iron armor. Note that it is a complete iron armor, and it has a physical object. Although later generations also excavated iron helmets from the Warring States period, or called iron helmets, but the complete supporting equipment was not discovered at the same time. Iron body armor. Of course, this does not mean that no body armor has been excavated during the Warring States Period, but those were either made of leather or copper. The earliest complete sets of iron armor were from the Han Dynasty.

Thanks to the tradition of a large number of burials in the Han Dynasty, there are many armors that have been handed down. Later generations probably unearthed seven or eight complete pieces, such as Liu Sheng's set...

Is seven or eight pieces considered too much?

Sorry, this number is really a lot. After all, the Chinese dynasties changed, but except for the braided dynasty that left some at the end, there are really not many 78 finished products that can be found from other dynasties.

The original armors of the Han Dynasty were actually very similar. Structurally speaking, these armors included body armor and shoulder armor. The covering part of the body armor included the chest, abdomen and crotch. Some body armors were also equipped with basin collars to protect the neck. The covering part of the shoulder armor is the entire upper arm. There are two types of shoulder armor. One is the shoulder type and the other is the half-sleeve type.

Regardless of body armor or shoulder armor, they are all made up of forged iron armor pieces. One is a small oval armor piece? The other is a rectangular large armor piece? Whether it is a small armor piece Small pieces or large armor pieces are all connected with ropes to form an armor.

And here we are, the final version of the Han Dynasty armor.

At most, in order to distinguish one's identity, the armor will be inlaid with gold or silver, or some patterns will be struck to create a gap between it and diaosi products...

Then, suddenly there was an extremely death-phobic, uh, technology-focused Fei Qian, who began to make a huge push for Han Dynasty armor from the inside out? So much so that the armor technology made a sudden leap forward, almost approaching that of the Tang Dynasty. generation.

Of course, there is still a certain gap between the real popularity of Mingguang armor on a large scale in the Tang Dynasty.

Because Fei Qian is so generous with armor, some problems inevitably arise.

For example, fraud.

On the whole, Fei Qian's attitude towards craftsmen is relatively generous. He can even allocate certain resources for tilting. For example, if Ma Jun needs to make a wheel ship, Fei Qian will satisfy the required materials and manpower to the greatest extent possible.

, however, such treatment made a small number of people start to have some bad thoughts.

After all, it is difficult to truly innovate, but it seems that it is not so difficult to fake...

Fei Qian never thought that in the Han Dynasty, we would encounter something similar to that of later generations, where "technology is based on changing shells."

At this stage, the most troublesome problem for Fei Qian's large number of equipped Zhajia is the problem of rust prevention.

Yes, it's not a matter of defense, but of rust prevention.

In terms of defensive power, Fei Qian has gone through many studies. In terms of Chinese armor style, due to the mixture of complex terrain and various wars, the Western European model of full-body plate armor looks powerful and has poor defensive power.

Powerful, but not suitable for Chinese Legion operations.

When it comes to the top equipment to defend against arrows, it is naturally chain armor. To defend against being stabbed by swords and spears, it is naturally plate armor. As for heavy weapons that contain powerful power, to be honest, in the face of pure power, it is difficult to rely on armor for everything.

Defensive.

Zha armor is almost the most perfect armor at the moment. It has a certain degree of defense against bows, arrows, swords and guns. The cost is relatively cheap, and the production process is mature. The most important thing is that it is relatively simple for soldiers to maintain, and they don’t even need to arrange special craftsmen.

, the soldiers themselves can handle it.

However, rust removal is still a very tedious task, especially at the turn of spring and summer, and during the rainy season, what soldiers often do is to remove the armor pieces, then polish them, paint them, dry them in the shade, put them back, and then rub them off easily in two days.

The areas where the paint comes into contact with the outside air begin to rust again...

It is precisely because of this that Fei Qian issued a long-term task to the iron-making craftsmen, which is to study alloys, especially stainless steel series alloys. Of course, Fei Qian also knew that he wanted to make stainless steel or something similar to stainless steel in the Han Dynasty.

The material is impossible, but just because it is impossible in the Han Dynasty, it does not mean that we should not study it. At least, the various experiences and formulas left during the research process can provide more metallurgical experience for later dynasties.

Perhaps in later generations, China took several steps forward and took the lead in the world because of Fei Qian's advanced alloy research? So in fact, Fei Qian did not hold much hope that someone could complete this task in the Han Dynasty, but it contained

Including the bad taste of some time-travelers...

So, when someone among his craftsmen reported that he had discovered and successfully made a metal that would not rust, Fei Qian felt that something was wrong.

"Is this stainless gold?" Fei Qian looked at the bright piece of armor that had been connected with leather hooks, and then looked at the craftsman in front of him, and asked with a half-smile.

This is very interesting.

The armor shows a bright color, and the surface is very smooth and bright. It sparkles under the sunlight, and indeed there is no trace of rust at all.

The craftsman fell to the ground and replied: "Yes, exactly..."

Fei Qian looked at it carefully for a moment, then smiled and said, "Where did this thing come from?"

The craftsman replied: "Little man, little man... you melted silver into molten iron and merged to get this thing... It looks like silver but is actually like iron. Even if you don't use paint, it won't rust easily..."

As we all know, oxidation of silver is common, and blackening is also common, but its resistance to corrosion is still very strong, so if it is really a silver-iron alloy, it does have a certain degree of corrosion resistance, although the strength is not as good as that of silver.

It's stainless steel, but it's also a very good alloy material.

But the problem is...

Fei Qian laughed twice, and then said in a deep voice: "Is it really obtained by melting silver? Is it not forged and overturned?"

Beads of sweat gradually formed on the craftsman's head and dripped on the ground. "Small, small... it really is like that..."

Fei Qian hummed, and then gestured to Huang Xu, "Tear out a few pieces of this armor and cut it off!"

Huang Xu immediately stepped forward, pulled out his knife, and then cut off the leather cords connecting the armor plates. He took out a few shiny pieces of armor, placed them on the stone, and chopped them off with a sharp knife!

Silver itself is relatively soft, so this so-called "silver-iron alloy" can be easily cut.

Fei Qian took the piece of armor that was broken into two pieces, then took a look at it, sneered, and threw it in front of the craftsman. "Is this a fusion of silver and iron?"

The half piece of armor clinked on the ground, bounced slightly and then lay on the ground. The difference between the outer layer and the inner tube could be clearly seen at the break...

The craftsman collapsed to the ground and could not speak a word.

"Drag them out!" Fei Qian waved his hand, "Relevant persons will be dealt with according to the law!"

Several soldiers rushed up and dragged the craftsman out like a dead dog.

Liquid silver and iron will not fuse with each other at all! Therefore, whether it is injecting silver into molten iron or adding molten iron to molten silver, they will not combine with each other to form an alloy. Silver-iron alloys are

It can only be produced under specific conditions, and the Han Dynasty did not have such conditions at all.

Fei Qian didn't even need to ask about the motive. It was probably the craftsmen who used this name to spend a lot of silver, and then made such a so-called "silver-iron alloy" that would not rust to make up for the so-called "loss", and then his officials

I don’t know the secret, and I report it as performance without even checking it in detail...

Fei Qian frowned slightly. This is a problem of mismatched majors. Nowadays, most officials come from scripture families and do not know anything about industrial technology.

It is easy for this kind of problem to arise. If Fei Qian had not had some knowledge of later generations, he would not have believed that this was a real "silver-iron alloy".

so……

Just take the exam.

Business exam.

However, this will have to wait a little longer, at least until the issue of "amnesty" is finalized...

……┐(?～?)┌……

On Cao Cao's side, the soldiers naturally also need to wear armor, so there is also the issue of armor.

After Cao Cao endured several times of bullying from Fei Qian, he also felt that he could no longer endure such inhuman pain, nor could he go to Fei Qian's caravan all day long to obtain those obviously inferior armors.

So the word "autonomy" awakened in Cao Cao's mind.

It’s not that we don’t have blacksmiths, we also have iron mines, so what’s the problem?

Start independent research and development!

When Cao Cao was financially strained and even had to tighten his belt sometimes, he allocated nearly 3 million yuan to Xu County Workshop to develop or imitate Qiusi Feiqian's armor series.

From soldiers to generals, from sleeve armor to Mingguang armor, especially the set worn by Fei Qian and those senior generals, it is said that it looks heavy but feels light when worn...

Now, in the workshop of Xu County, the official in charge of armor research is covered with sweat, his eyes almost bulging out, gritting his teeth, and the flesh on his face is beating constantly, staring at the other people who are kneeling in front of him.

A small boss of the workshop said, "What did you say? It... broke again? Ah?!"

It’s great when you get research funds, and it’s great when you spend research funds, but when it comes to producing research results...

If you want to be happy all the time, you have to get some things out, especially the high-end armors from the Hussars. From the Cao family to the Xiahou family, the school has been thinking about it more or less. Now if it means that the research will not produce any results, then the result is certain

It won't be any fun anymore.

The official who was in charge of armor research even began to feel a chill on the back of his neck, as if a beheading knife was being held behind his head. He couldn't help but reach out and touch the back of his neck, feeling the cold sweat on his hand.

"Do you know? If you can't make the armor, you and I will be punished by death!" The official grabbed the little boss and pulled him in front of him. "I don't have much money to give you. How did you get that yard in the east of Xu County?"

Ah? Now you tell me that the support is broken again?! How do you want me to explain it?!"

Most of the weight of Han Dynasty armor is on the shoulders. It can be imagined as an iron sack with the head exposed. In other words, almost everyone wearing armor is equivalent to carrying a burden to fight with others. For shoulders

The pressure is very high, so in the Han Dynasty, generals were described as having "extraordinary arm strength", "both arms have the strength of a thousand catties" and so on. After all, this is the requirement. Those with smaller arm strength, let alone brandishing weapons, wear armor.

You may not even be able to straighten your back.

However, the armor of Fei Qian's senior generals has a layer of steel support structure added inside the armor. It can be roughly regarded as the reinforced concrete frame of a building, and those armor pieces, brick walls, etc. added later have a heavy weight.

It can be shared by this structure, and then the burden on the shoulders can be released, and most of the pressure can be transferred to the waist.

Obviously, after such changes, the flexibility of the shoulders is greatly improved. At the same time, due to the lowered center of gravity, although the overall weight is heavier than the original armor without internal structure, after wearing it, it will feel
To be continued...
