From talking about cooperation to signing the contract, it only took half a day, but from top to bottom, no one felt that this was a behind-the-scenes deal.

The Ministry of Industry and the Iron Smelting Division, this is more professional, perhaps in the late Northern Song Dynasty and the Southern Song Dynasty, there will be corruption, in the late Northern Song Dynasty, the 800,000 forbidden army is a showcase, the so-called step people's armor, almost like paper paste.

But in the early Northern Song Dynasty, it was different, every weapon, every piece of armor, was signed with the name of the craftsman, in this case, the armament of the forbidden army was quite elite.

As far as the several major battles of the Renzong Dynasty are concerned, not to mention the south, it was crushing, the great war in the northwest, and the three famous battles of the founding of the Western Xia Dynasty, all of which seemed to be the fiasco of the Northern Song Dynasty, but the central forbidden army, the core main force, did not suffer much.

As Han Qi's eternal pain in the battle of Shuichuan, the Central Forbidden Army lost more than 10,000 people, but it was under the encirclement and suppression of 100,000 cavalry, and it did not retreat, and was finally annihilated.

Under the Western Xia cavalry, where everyone was a soldier, the forbidden army dominated by infantry had a 1 to 10 disadvantage, and it was a field battle, and the other side did not achieve a beautiful annihilation battle, which can also show the strength of the forbidden army.

It is precisely because of the rigor that everyone recognizes the quality of this iron material, and for the first time, it did not follow the previous agreement, the quantity of 1.5 million catties per month.

In the first month, the Daimyo's government had sufficient funds, plus the need to replace and repair weapons, and the amount of iron needed was large, and in the first month, the blacksmith workshop supplied 3 million catties at one time, as well as 5,000 catties of steel.

This was also decided in consultation with Cao Di, and Zhao Xin mentioned that the price of refined iron has also been reduced to a level that is no different from the previous iron price.

Refined iron is better than iron, this is known to everyone, and Cao Di also knows that this fine iron is definitely not the kind of divine weapon, it is unattainable, but as long as it reaches the level of fine iron, it is worth it.

In addition, this fine iron is only 100 Wen a catty, and after getting the real thing, it has passed the test of the blacksmiths, and on top of the general fine iron, even Cao Di is tempted.

Although the Daimyo's capital is tight, there is no shortage of such 500 runs, maybe it should be a good choice to use these 500 knots to build 1,000 sets of fine iron step armor.

The Northern Song Dynasty Forbidden Army, the infantry armor is almost popular, but among these infantry armor troops, there are some trump cards, their infantry armor is as high as 45 catties, which is nearly twice that of ordinary infantry armor, greater weight, but also brings greater protection, plus some fine iron to build knives, they are elite, is used on the battlefield to break the situation and chisel through the existence.

However, fine iron and iron, these are two completely different concepts, even the most elite troops, can be used to build a long knife, a long knife is only seven or eight catties, and it can be bearable.

According to the previous standard, the cheapest fine iron, 400 Wen per catty, plus the fine iron is far more difficult to process than iron, the whole cost, it turned over, got 800 Wen per catty, a set of the same as the ordinary step armor, on the fine iron, to be heavier, a set of ordinary foot armor may be as high as 35 pounds, and the comprehensive protection is as high as about 60 pounds.

Fifty or sixty is really not much, but with the support of 1,000 people, two thousand, or even more people, it is a bit much, not to mention a piece of equipment, step armor is only a part, as well as weapons, helmets, and other auxiliary equipment, it is possible to equip a forbidden army, and the total investment may exceed 150 yuan.

This is completely unacceptable, 150,000 people and 1,000 people, I don't dare to take it after thinking about it.

However, the fine iron provided by the blacksmith's workshop is 100 wen a catty, and the price is only a quarter of the previous one, because it is relatively light.

It cannot be said that the previous refined iron is not good, in the absence of a reasonable manufacturing method, in order to increase the final strength and effect, a certain alloy may be added, such as heavier, the general standard refined iron, will be between 20% and 30% heavier than iron.

But in fact, steel is just an alloy of iron and carbon, carbon is much lighter than the specific gravity of iron, and the weight of a truly qualified steel should be between eighty-five and ninety-five of iron, and its weight is lighter.

The standard fine iron supplied by the blacksmith's workshop is the simplest, most common steel, and the carbon content is not accurate to a certain extent, that is, it is almost 1% lighter than ordinary iron.

That is to say, the weight of about 30 catties of Buren armor is about 27 catties, and the most important thing is that the iron provided by fine iron is also the appearance of the iron sheet of Burenjia, and it has been drilled.

After knowing the difficulty of drilling in the Ministry of Industry Bureau, the blacksmith workshop also took the initiative to undertake this, because the amount of iron was too large, there was no way, and iron was easier to process, so it was not done, and fine iron was done by the way.

I took out harder metals and alloys and made a drill machine like that, which was simple enough to process these steel sheets, and I don't know how much faster it was than that of the Daimyo.

Because of this, almost 7 percent of the manpower was saved, and then, the steel sheet was compiled into a step man's armor, which was just a kung fu, so down, the price of each catty of step people's armor was reduced to about 150 Wen, if you added the amount of reduction, a set of fine iron made of people's nails, the price was actually similar to the previous purchase of people's nails, about 25 pounds, and the total price did not exceed 4 times.

Hearing this estimate, Cao Di almost didn't have an order to change the previous contract and replace the iron with fine iron.

But in the end, he still endured it, replaced a small part, and even supplemented the maintenance, and invested fifty or sixty thousand yuan per month, which is no problem, but it is replaced with steel, which is doubled, and there is no problem of replacement, fine iron and iron, these are completely two concepts, with fine iron, who still uses iron.

Then the number of replacement of the Daimyo Mansion is an astronomical number, and the Daimyo Mansion has about 200,000 sets of infantry armor, all of which are replaced, which is 800,000 Guan, plus many other weapons and weapons, the overall cost may exceed 3 million Guan.

This money is not something that the Daimyo Mansion can afford, so make it simple, popularize a few thousand sets first, and then create two elite armies.

Because of the sample, I am looking forward to this cooperation, and I also hope that the blacksmith workshop will deliver it earlier.

3 million catties of iron, which sounds very huge, is an astronomical amount for any blacksmith shop, and it can never be reached, but for a blacksmith workshop, it is only three or four days' output.

However, now in the blacksmith's workshop, there is not much pure iron, most of the finished products have been produced before, and there is not much iron accumulated, but under the premise of transferring the production capacity, it only took 5 days to complete the production, and the speed shocked everyone.

Cao Di already knew the output of the blacksmith's workshop, because with an output of 300,000 catties per day, it would be at least 300,000 catties per day.

He is more concerned about the performance of this iron material, sure enough, the following investigation, rave reviews, because most of these iron materials are used to make step armor, one third of which is the form of iron sheet directly step person armor, there is no hole, but a lot of effort is saved, it seems that a set of step armor is far higher than the cost, it is this kung fu.

Starting from the creation of each piece of iron, the most laborious thing is the process of the iron piece and the subsequent chiseling, and now the most laborious work has been completed, which is equivalent to saving almost half of the effort, which is also a great benefit for the blacksmiths.

The blacksmiths of the Ministry of Industry are not like blacksmith workshops, they get a fixed monthly salary, and now they work the same, but the amount is much less, and everyone likes it, which means that they spend less time to do a day's work, and the rest can be married or rested or do something else.

Not only is it convenient for processing, but also some problems about quality are fed back, and the overall quality is quite good.

Cao Di does not doubt that the workshop that can make magic weapons and make good quality iron is certain, in his intuitive consciousness, the better the quality of the iron, the higher the cost, there is no reason for better quality, but the price is only less than half of the previous one.

If Zhao Xin lied to him and took a few hundred catties of samples out, but falsified the number of 3 million, in this case, he may only swallow this dumb loss.

However, this is within the controllable range, 100,000 guan, which is not too small a number, is bought with iron, no matter how bad it is, it is worth a little money, and it is a big deal to waste some effort and re-cast, that is, a loss of one or two thousand guan.

It is precisely because of this confidence that Cao Di waved his hand and set this deal, about 100,000 yuan, not too high, not too low, if Zhao Xin does it from the middle, then there is only such a once.

Only the daimyo who stayed in such a position would dare to do so, but after receiving it, after sending senior craftsmen and investigating most of the iron materials, all the subordinate officials in charge were stunned, and all the iron materials were neat and consistent, and they were exactly the same as the previous samples, without any problems.

Their brains can't figure it out, similar shortages of catties and two, maybe not in large transactions, the color is a little worse, and there are more impurities, this is the most normal thing, 3 million catties, of which half of them are mixed with one grade, or two grades, this is no problem, such a cheap price, they will also pinch their noses and admit it.

But it's all like this, how these good irons are refined, and why are they only about half of the previous price.

Of course they won't believe that Dinghai Hou lost money and made a lot of money, and he lost 100,000 yuan at once, not to mention an ordinary family, even if it was the center of the court, it was enough to take out an official of more than three grades.

I don't understand, I don't understand, the thing is good, it's still the appearance of the step people's armor, it saves a lot of time, iron ingots and the like, it's also very good, easy to refine and use, in short, this blacksmith workshop is very professional, as long as it maintains such quality, it doesn't matter if it is handed over to him in the future.
