"The foreign minister thanked Bai Gong for his love on behalf of the prime minister, and wanted to come to Bai Gong Kuang's heart to help the Han family, and the prime minister can also understand it, but whether the transaction can be carried out, the foreign minister does not dare to guarantee it." Sima Lang said.

Of course, Sima Lang estimated that Cao Cao would probably buy it in the future - after all, a saber of this quality was also very rare in Cao's army, and it was ...... Iron tools, or even well-made weapons, wouldn't it be difficult to get along with yourself if you didn't buy them?

It's just that you have to be deeper first, and then it's good to keep the price down.

When Zhang Zhao heard that he was going to sell, he was even more anxious.

Although Koto is rich in copper and iron, it is ...... Now in this stall, how can there be a reason to sell weapons?

He just didn't want to see that Jiangdong, which was getting better and better, used all his strength on ordnance, not to finance the enemy!

But just as he was about to speak, he saw that the old man Lu Kang was sitting firmly at this time, so he stopped talking - he believed that this kind of thing, the lord should have informed Lu Kang, and since the lord could persuade Lu Kang, he thought he had his own reasons.

And that's exactly what happened......

Talking about mineral reserves? Iron ore and copper ore are Jiangdong's strengths, even in later generations, Jiangdong is second only to the northeast in iron ore, and second only to Yunnan in copper ore - now these two places, one is Fuyu, the other is Nanzhong......

The latter barbarians are everywhere, even after Zhuge Liang captured Meng seven times, Nanzhong Barbarian did not stop for a few years, but the transaction was smooth a lot, and the former is still the Fuyu State - the lord of the country is now the son-in-law of Gongsun Du, which is a foreign state dependent on Gongsun Du.

How many people did the Eastern Han Dynasty have? Yangzhou's copper and iron are abundant!

The reason why copper and iron are also very precious in Yangzhou is because of insufficient excavation.

As long as the rock drill can be built, the black powder is ready-made, and the most simple and crude trick of "blowing up the mountain" is learned, which is enough for Jiangdong's minerals to increase several times compared with the current production that can only be excavated shallowly......

What's more, when exporting strategic materials, Baitu must also collect strategic materials - grain and grass from the Central Plains, ore from Liaodong, and horses from the north......

In this way, not only can the Ministry of Industry be able to maintain its expenses, but it also has an additional benefit...... If you directly connect with a certain family and recognize the other party as an "agent", then ...... Are the local princes in response, or in response?

As soon as Bai Tu thought of this, he looked at Sima Lang's eyes, and became a little kinder.

Sima Lang didn't know what he was thinking, but he instinctively shuddered!

"It's okay, I'm just saying casually, you don't have to be stressed, Boda...... Liu Yuanjun of Xuzhou should also be interested, the Gongsun clan of Liaodong and the Ma clan of Xiliang...... Now they are all protecting the people of the Han family and deterring Qianghu Xianbei, I believe they will also need these, and the Prime Minister's Mansion does not have to take it too seriously. Bai Tu raised his glass and said.

Sima Lang's face froze when he heard this-is this telling the Prime Minister's Mansion not to take it to heart?

Liaodong and Xiliang something, he didn't believe that Bai Tu could sell the sword, but Xuzhou ...... Not to mention, Jian Yong from Xuzhou is also at the banquet now!

Could it be that Bai Tu got this idea?

Bai Tu no longer paid attention to his appearance, and Pang Tong on the side also said in a timely manner: "Lord, the Ministry of Industry has recently designed and created a new battle armor, using a new concept and design style, and I hope to take this opportunity to dedicate it to the Lord's Tiger Ben!" ”

"Submit." Bai Tu said.

I saw a few big men again, and the two of them came up with armor one by one......

Heavy, all described as "seats" - two big men with big shoulders and round waists, and four pieces of armor on one pole.

At this time, the armor of the Eastern Han Dynasty, Ji Zao soldiers were mainly armor, and the generals were usually loaded with scale armor - it had to be some grades of generals, and the general army commander and even the chief did not have this treatment.

The so-called armor is a leather armor inlaid with large pieces of hard sheets, mainly to protect the two chests and two ribs, the inferior point is the hardwood piece, and the best one is to use iron or copper sheet.

Of course...... That is, the equipment of the Yangzhou army is neat, otherwise the third-rate army of the general princes is usually leather armor and cloth, and even the armor can only be equipped with the first and second line of troops.

As the name suggests, the scale armor is a fine scale armor iron sheet, which is embedded in layers on the inside, and the coverage rate is higher in comparison.

These are all old crafts that existed in the pre-Qin period, although they have been improved, but the general foundation has not changed.

In the history without the White Rabbit effect, the armor of the Three Kingdoms period has also improved a lot - like weapons, the most able to promote the transformation of armor is war!

Chain mail began to appear in the Three Kingdoms period, and the prototype of Mingguang armor appeared in the later period......

The former is a small iron ring linked together to form armor like an "iron net", while the latter is a large piece of copper and iron like a heart goggle to protect the chest, abdomen, and back, and is generally used in combination with chain mail or scale armor.

After the development of the Wei, Jin, Southern and Northern Dynasties, the chain mail and Mingguang armor in the Tang Dynasty were among the "thirteen armors", and at the same time, like the popular mountain armor in the late Tang Dynasty, it can also be regarded as an optimized variant of chain mail - each iron ring is no longer a ring, but presents a mountain shape, and is woven together with each other.

In the late Tang Dynasty, Mingguangjia gradually withdrew from the battlefield......

On the second major change in armor, it is the step armor that appeared in the Song Dynasty!

Although it was nailed to the "coward" of heavy literature and light force, the heavy infantry of the Song Dynasty was indeed brilliant......

The Song Dynasty, which lacked cavalry, was able to fight with the Liao and Houjin in the north, and it was precisely by relying on the powerful and fat heavy infantry!

The basic small unit of the Buren Armor is no longer a "ring", but a piece of armor leaf weaving, just like the armor of his old enemy, Houjin's Tiefutu, which is a bottom-up, layered structure.

Compared with chain mail, the anti-long-range ability of the infantry armor has been greatly improved, although it cannot resist the bow and arrow in the center, but at least in the face of stray arrows and projectile arrows, if it is not too unlucky, it will not be shot through.

And as an infantry armor, the designer of the infantry armor of the Song Dynasty was also working hard to "tired cows".

Another feature of the Infantry Armor is that it can be equipped with more armor to further improve the defense class, and at the same time, ...... Also heavier!

The heaviest is the armor of the spearmen, because the spearmen of the Song Dynasty had to bear the heavy responsibility of blocking the cavalry charge, so they ...... Really heavy.

Under normal conditions, the weight of the spearmen is sixty or seventy pounds of later generations, and in the fully armed state, it is more than one hundred pounds of armor - if you want to be a deserter, you have no chance!

The lightest crossbowmen are heavily armoured, and there are seventy percent of the spearmen......

Even if it is a "general state", it is already the pinnacle of ancient and modern, Chinese and foreign, cold weapons and armor.

When marching, you need to push the armor like a baggage, wear only the inner armor, wear full armor when on alert, and only bring the pylons when you go to war!

Therefore, the Song Dynasty was heavily armed, and there was no need to think about any rush and encounters, but only positional warfare, and there was no need to chase the enemy together, not to mention that it could not catch up, and if it ran a few more steps, it was afraid that it would be counter-killed......

If you lose, you don't have to think about running, the opposite side can catch up with you with one leg!

And under the command of Pang Tong, these carried up look like scale armor at first glance, but they are denser than scale armor, and the coverage rate is far more than that, if you look closely, you will find ...... It's made of pieces of nail leaves!

You don't need to experiment, look at these wrestlers snorting and tired, and you can feel a sense of security when you listen to this armor on the ground.

It's just that...... The guards looked at Pang Tong one after another.

Although armor is also a guarantee of life, it ...... Who designed this to be tired?

Also design concept, design style...... This Ministry of Industry is very bad!

Pang Tong seemed to feel everyone's resentment, shook off some of the hair that was no longer flowing, smiled slightly, and asked the wrestlers to show it separately.

I saw that it was like a nesting doll, and the outermost layer of "click" several parts was disassembled, and I suddenly felt a little more streamlined, and then lifted it again - the outer layer of armor was lifted up together with the pylon, revealing the inner armor......

Pang Tong also introduced in detail the advantages and disadvantages of this "heavy armor".

When loaded into the battle armor, the original defects of the step armor actually have a great compensation - the principle of the battle armor, the white picture can not be explored, but it is certain that after loading the step armor, it is usually equivalent to the bulky step armor, and it has also received the "soldier talisman".

In terms of marching, there is no additional burden.

On the contrary, the battle armor has three forms, one is the ordinary marching form, the second is the battlefield form, and the third is the enemy form - the defense is increased in turn, but the restraint of flexibility and speed is becoming more and more obvious.

"Can you equip the whole army?" Bai Tu asked.

Hearing Bai Tu's words, Zhang Zhao almost bounced up from his chair......

Fortunately, Pang Tong shook his head and said: "Lord, this kind of armor is quite expensive, and if it is equipped with ordinary Ji soldiers, it will be very inconvenient, and it will be ...... at the tactical level It's not all about it. ”

Nonsense!

Was the Song Dynasty fat? More than a million troops, 800,000 forbidden troops alone!

But...... When the armament was at its most complete, counting the troops of Han Shizhong and Yue Fei, those who could be called fully armed were only in their early 100,000s.

As for the heavy cavalry Tiefutu of the Jin Kingdom, it was only 5,000 in its heyday.

"Well, let's equip it gradually! It was first popularized among the commanders and commanders, and then the number of heavy armor needed by each army was counted. Other than that...... Ordinary light leaf armor should also be equipped with the whole army three years ago. Bai Tu said generously.

Of course, this is what Bai Tu has known and decided for a long time, and the reason why he is saying it now is just to remind Sima Lang and Jian Yong that they - the armor and scale armor are also sold!

"Whoa." Pang Tong responded.

At this time, Bai Tu also praised Pang Tong again, and announced that all the officials of the Ministry of Industry had their performance upgraded by one level, and the officials involved in the Jian'an Four Sabres and Jian'an Four Leaves A project should be rewarded for their meritorious deeds!

However, Pang Tong didn't have anything to lose, he only felt that this was all the skills that Bai Tu taught him, but he was slow to learn, so there were so many "transition products".

In fact, Bai Tu and Pang Tong both know that there is another kind of armor that is more practical than the infantry armor, that is, the plate armor that can really "overcome the spear with a shield" - it is cast from a monolithic, two-millimeter-thick iron plate, and the weight is lighter than the heaviest infantry armor, and the defense is ...... For direct arrows fired head-on, you can guarantee a blocking rate of eight or ninety!

It's just that plate armor needs to cast iron - in which carbon exists in the form of flake graphite, which can only be cast and cannot be forged, and can cast large pieces of pig iron, also called "cast pig iron", which corresponds to "steelmaking pig iron" that can only be forged and not cast.

Theoretically, blast furnace ironmaking can be used to smelt cast pig iron, but now the process has to be gradually improved, and only "steelmaking pig iron" can be smelted at present, so the armor process still chooses this kind of spliced step armor.

At the same time, even if cast pig iron is smelted, to produce plate armor on a large scale, at least a hydraulic forging machine will be needed......

At this time, Pang Tong also took the initiative to mention: "Lord, the affairs of the Ministry of Industry are becoming more and more complicated, especially in terms of organ structure...... Increase the recruitment of talents in the selection test and the recruitment hall! ”
