Things are right, and the quality is so good, this can't mean that it will always be like this, but a one-time 3 million catties are like this, which also represents the strength and ability of this blacksmith workshop, not to mention speed, even if it is the quality of these goods, it is enough for them to choose this product.

Because this is the first cooperation, Cao Di also attaches great importance to it, from beginning to end, he has sent subordinate officials to supervise, and he knows how smart the people below are, and he immediately attaches great importance to it, not only to come up with an overall assessment of quality, but also to come up with an evaluation of savings.

This assessment can basically be roughly estimated, but there is no such horror in the calculation, after reporting layer by layer and coming up with an assessment of the overall wave of orders, even the subordinate officials can't sit still.

The reason is very simple, it was just an estimate before, and sometimes, when people dream, they also estimate that they can get a lot of money, and it is estimated that it is different from the actual thing.

Now, when the first wave of 3 million catties of iron is in place and put into the actual production process, everyone does not dare to say anything, and the chief officer of the Ministry of Industry can quickly calculate the amount of savings in a year, which is a terrible and suffocating number.

According to this contract, if it is performed in a year, it will be about 600,000 pieces of iron, but it has done what was not done before, or even 1.5 million times, and the one-time savings may exceed 500,000 yuan.

The Daimyo's Mansion is considered to be a smooth business and trade, a place with a high annual income, and a lot of appropriations from the imperial court, but five or six hundred thousand guan, or even close to one million guan, even the three envoys have to be moved, not to mention Cao Di, a Hebei pacification envoy, and the daimyo guarded.

When the final report was made layer by layer, and when it was reported to Cao Di, Cao Di was also surprised, and after knowing this, he sighed and stopped talking for a long time.

Sure enough, it is not leaking, and I still want to use this thing to repay the favor, who knows, not only did not pay it back, but owed a greater favor, in the next year or two, the Daimyo Mansion is full of ideas, there are several large projects, and they are about to face the danger of stoppage, and now it seems that there are 600,000 yuan to supplement, it seems, there is no need to stop.

Looking at the folds in his hand, he wanted to write a few words lightly, and it seemed that he had to focus on writing, a daimyo's mansion would be reduced by 600,000 per year, and it would be extended to the entire forbidden army, and even the entire army of the Northern Song Dynasty, how much would it be reduced, even if the number of changes every year was not much, but 3 million to 5 million, this is certain, when the time comes, no matter what the center is, Ye Qingchen will definitely pounce.

Cao Di and Ye Qingchen have a good relationship, and he is also very aware of Ye Qingchen's character, in fact, Ye Qingchen is not as suitable as being a third envoy, the reason is very simple, his cautious character, coupled with his talent in business and taxation, what is he doing if he doesn't do this.

Chief, Ye Qingchen really doesn't have this ability, in terms of controlling the court, in determining the major policies, Ye Qingchen can't do it.

But he also knows that these days, what kind of life Ye Qingchen is living, you must know that the Northern Song Dynasty is now in a thousand troubles, and the military expenditure is getting more and more prosperous, and the reason why there are more and more people who agree to negotiate peace with Western Xia is because of this.

What kind of place is Xixia, it is a place of rebellion, a few decades ago, Xixia still belonged to the territory of the Northern Song Dynasty, but Yuan Hao's father and son have been here for a long time, have strength, and gradually rebelled, coupled with Yuan Hao's ability and ethnic minority reasons, in the end, he became the climate.

But unlike the Liao State, before the establishment of the Northern Song Dynasty, the Liao State was a powerful country in the north, and it was no problem to negotiate peace with them, even if they were called brothers, there was no problem, but in the Western Xia, it was a little difficult.

Reality, so that the Northern Song Dynasty had to bow their heads, the Western Xia non-stop Koubian, the increasingly severe border situation, plus more and more expenses, these are the fundamental reasons for the Northern Song Dynasty to bow their heads, if you can use the cost of 300,000, 400,000 in exchange for peace in the northwest, then what you save is millions, or even tens of millions of investment.

Every military general of the Northern Song Dynasty wanted to bulldoze the Western Xia and extinguish the rebellion, but there was no way, the Western Xia was like a small strong man who could not be killed, the stronger it became, the bigger it was, the more uncomfortable it became.

Now, the price of this iron material has been reduced, although it cannot completely solve the problem of Western Xia, but it can solve the financial problem, as long as the military can have a balance of more than 3 million guan per year, the imperial court will also take a breath, and the military can even accumulate enough funds, with tens of millions of guan, it is enough to start a big war.

If you don't solve the Western Xia, it will always be a problem, unlike the Liao State, although the Western Xia was founded, but in their bones, they are a nomadic people, their habits make them not abide by the agreement, once they encounter a disaster, or when they can't survive, they will definitely do it, and they will fight.

The problem of the contract is just to stabilize them in a short time, in fact, only two or three years later, Xixia once again Koubian, that time, when Yuan Hao died, and then, small-scale conflicts continued, and this contract also became a fixed benefit of Xixia, and even some Koubian was also used as a threat.

Cao Di thought a little far, but if he really wanted to succeed, this money would be saved in the end, which would be the best thing for the entire Northern Song Dynasty.

I carefully wrote a good note, it seems that it can't be used, and it must be changed before it can be sent.

The Daimyo's Mansion and Bianliang are in close contact, 400 miles away, whether it is 800 miles expedited, or other contact methods, you can quickly facilitate the contact between the two times.

After Zhao Xin came, took out the sample, and finalized the first stage of cooperation, this letter was written, but now there is a new situation, and Cao Di spent another day revising it, mainly highlighting the quality and price of iron.

In these two aspects, iron is different from other items, likes and dislikes determine everything, you say that this three runs a tael of rouge is good, I prefer another 500 wen one or two rouge, this thing, is a subjective feeling.

Sometimes, the scent, and the feeling of applying it to the body, is a key, and a little subjective sense is enough to decide whether to use the product or not.

But iron is different, a pound of iron, the price is low, it is an advantage, good or bad is not based on feeling, there are certain performance indicators, this index, can even be experimented, through use, testing, this is a rigid standard.

The iron in the blacksmith's workshop is not a little better, it is much better, and in front of any blacksmith, even if it does not have to be a senior, some apprentices can see the good or bad between the two.

In fact, it is exactly like this, iron follow-up, it is still different. The same is iron, but the impurities are different, plus some quenching and building methods, but they can produce a certain improvement, this improvement compared with steel, there is a large gap, but the difference between pure iron itself, is a huge.

For Zhao Xin, seeing the steel smelting in the future, he actually doesn't think that steel is much more expensive than iron, some high-grade iron, his cost, will not be much worse than steel, or even more, not afraid of shocking the world, Zhao Xin will directly take out the steel, but to accept, and large-scale replacement, that requires huge investment, but also a lot of courage.

If you want to replace hundreds of thousands of sets of equipment, million-level weapons, and other engineering equipment, and iron vehicles, this requires steel is not a small amount, even if Zhao Xin takes out the price of the cost and the price of loss, this total amount is also a terrible, it may exceed 10 million figures, this number will scare the center of the Northern Song Dynasty to death.

But iron is not the same, it is still iron, even if the performance is a little higher than the general iron, the relationship between the price, for replacement use, there are still not many problems, there is no large-scale replacement problem, just in the adjustment and conventional replacement, focus, this is like boiling a frog in warm water, take your time, the same effect, when the total amount reaches a certain level, you can solve the steel in a timely manner.

The iron-smelting process of the Northern Song Dynasty is quite developed, and the cold forging method has changed the military system of the Great Song Dynasty.

In other words, in terms of strength, the strength of cold forging iron is about 4.1, and the strength of the iron provided here is about 4.3.

It seems that it is only an increase of 0.2, but the span of this hardness is huge, to more than 6, every 0.1 is a huge difference, maybe in one or two intersections, it can not be seen, but there is a huge improvement in the overall indicators such as sustainability and hardness.

Even if it is the Northern Song Dynasty, which is not very scientific, the difference between this can be seen for experienced blacksmith masters.

This time, Cao Di did not use the eight hundred miles of expedited, from his acceptance this time, simply said, can not solve the problem, must get the real thing, fortunately, there are a lot of craftsmen in the Daimyo's Mansion, under the premise of concentrating most of the manpower and material resources, 5 sets of iron step armor plus 5 sets of fine iron step armor have been completed, Cao Di did not leave a piece, all sent vehicles and ships, transported to the capital.

The speed of the vehicle and ship can reach thousands of miles a day, and the vehicle and ship in the military system is faster, because there is no need to consider the room for manpower, half an hour, or an hour to change it, so under the relay, the speed is faster.

The distance from the Daimyo's Mansion to Bianliang, Tokyo, is more than 400 miles, and the waterway is a little longer, but it only takes a little more than 4 hours to arrive in Tokyo.

For the sake of convenience, I hurried overnight, and set off after dark, which may have been a little more dangerous, but there were fewer ships traveling at night, and finally, I arrived at dawn.
