After the two sides greeted each other, Xia Zhu said directly: "Minister Wei, a consensus has been reached between your majesty and our leader, and our main task today is to reach a framework for our cooperation under such a consensus, I think we should all agree on this, right?" ”

"What Minister Xia said is very true, and I also hope that we can reach a relevant agreement in the fastest time." Wei Zheng also smiled and nodded.

"In that case, then I won't say something insignificant, just say it directly, regarding the issue of armor, we have already made a general strategy, yes, about the issue of Mingguang armor, we can sell it to you, but it depends on the quantity of armor you order to determine its price." Xia Zhu said.

"Quantity determines price? If we want a lot of quantity, the price is too high, we probably can't afford it, Datang's military spending is limited, and it has suffered natural disasters in the past two years. Wei Zheng came up and began to cry poor.

"No, no, Minister Wei, you misunderstood, it's not that the more quantity, the higher the price, but the more quantity, the lower the price." Xia Zhu said with a smile.

Wei Zheng was stunned for a moment, the more the quantity, the lower the price, what is the reason...... Wei Zheng almost asked this sentence, and Wei Zheng can't be blamed, there is no assembly line in this era, although there is a concept of industrialization to reduce costs, but high-tech products such as Mingguang armor and steel are definitely not within this range.

At least no matter how much Mingguang armor Datang produces, almost the cost will not drop too much.

"Then Minister Xia, tell me, how much can this price be reduced?"

"If Datang only orders 100 sets, then the price is about 1,500 pairs." Xia Zhu said directly.

Hearing this number, Wei Zheng couldn't help but jump in his heart, it's not that this number is too high, but too low, the price of Datang to make a pair of Mingguang armor is close to 6,000 guan, this number sounds very exaggerated, but in fact this price is real.

Of course, is there a way to reduce costs? Yes, that is a sign of a large number of craftsmen, the problem is that if these craftsmen are a sign of large-scale, just feeding these craftsmen is not a small number, and the cost is reduced...... And not much.

To put it bluntly, it is because the production time of Datang's Mingguang armor is too long, steelmaking takes a lot of time, and it also takes a lot of time to make steelmaking into one or two thousand pieces of iron, and then it takes a lot of time to link these pieces of iron perfectly.

Combined, these things come at a huge cost.

"But I think it's definitely impossible for Datang to order only 100 sets." Xia Zhu smiled again.

"Of course, what if it's a thousand?" Wei Zheng immediately asked.

"One thousand sets, one set needs about 1,200 guan, if Datang orders 10,000 sets of Mingguang armor, we can reduce the price to 590 guan, on the basis of 10,000 sets, Datang adds 1,000 sets, the price is reduced by 20 guan, and the minimum we reduce to 400 guan." Xia Zhu directly said the reserve price.

Wei Zheng and several officials almost couldn't hold back a breath of cold air, they had already seen the advantages of the Mingguang armor, Huo Gang chased and killed the 40,000 elite cavalry of the Eastern Turks with 30,000 cavalry, and his own casualties were less than 1,000, and he completely annihilated the other party.

This huge casualty gap comes from the terrifying protective ability of the Mingguang armor, you know, the 20,000 cavalry broke directly into the Turkic camp at the beginning, and the armor does not know how many times it was cut by the Turkic sword.

From this, it can be known that the deterrence capability brought by 10,000 elite Mingguang armored cavalry has a significant supporting role in Datang's next military operations.

"10,000 sets...... That's a good thing, but for now...... I'm afraid it will be difficult for us to come up with 5.9 million yuan, and Datang's treasury this year is not rich. Wei Zheng pondered for a moment and said.

"No, no, no, Minister Wei misunderstood, although it is a trade between brothers between our Datang and Dahan, but the monetary system of Dahan uses paper money on the gold standard, so we can't collect copper coins from Datang, I believe Minister Wei should know this, so we only accept gold."

"If this price is calculated according to gold, 10,000 sets is only 2 tons of gold, which is about 33 stones of gold, which is not too much." Xia Zhu smiled and said.

Wei Zheng was a little speechless, 2 tons of gold, are you embarrassed to say much? Since Dahan and Datang started trading, Wei Zheng naturally knew about the relevant weights and measures of Dahan, so he also knew how much 2 tons were.

And it's not just the Han Dynasty, in fact, because they continue to buy things from the Han Dynasty, many merchants in the Tang Dynasty now use the weights and measures of the Han Dynasty.

For this, although Li Shimin and they have discussed, it seems a little bad to follow the other party's weights and measures, but after careful discussion, they found that the measurement of the Han Dynasty is very more reasonable, at least Datang also uses the measurement of the city jin, but there are some problems with the base system between the city jin and the stone.

In fact, these are all left over from history, but Dahan has done a lot better here, and the other party has officially launched standard scales in various places, and these scales can make the people of Dahan weigh and measure without too many problems.

So after the discussion, Li Shimin and they thought about it, and they didn't force it, just let the people choose for themselves, the main thing is that they imported more things from the Han Dynasty, so naturally they used more weights and measures from the other party, which was also no way.

These are all side matters, and anyway, only a small part of the businessmen are using them, and they do not affect the overall situation.

However, Wei Zheng knew that what Xia Zhu said was true, if Datang took out 5.9 million copper coins, Datang would definitely not be able to take it out, but if Datang was asked to take 2 tons of gold, then Datang really had a way.

Because gold is not circulating in Datang, there are still a lot of gold in Datang's treasury, Li Shimin's inner treasury and folk gold, and the gold that is not in circulation is naturally gradually concentrated in the hands of the royal family and various gate valve families.

If Datang is willing to exchange money or other resources for gold, these gate valve families will naturally not refuse.

"Plus, we also accept barter." Xia Zhu smiled slightly and said, "We can ask for tea, silk, spices, medicinal materials, including high-end silk, but the price cannot be calculated according to the price of Datang's export to the Western Regions, it can only be calculated according to the market price within Datang, and even slightly discounted." ”

For the two points of tea and silk, in fact, Xia Zhu also has considerations, because after getting these things, you can also make money! The price of tea and silk sold directly by Datang to merchants such as Dashi is called a huge profit, but now Dahan is in the middle, although Datang's caravan can still go, but it is better to sell things directly to Dahan.

Then the Han Dynasty traded directly with the Persians in Central Asia, and could still exchange it for a large amount of gold.

At present, there is no development of high-grade silk in Dahan, mainly because high-grade silk embroidery and so on actually need manpower to complete, and industrialization cannot complete such a fine work, and the current machines of Dahan cannot achieve such precision.

The main products produced by the Han were low-grade fabrics and silks, and this part of the cloth and silk could also be used a lot of money because of the huge number of audiences, at least for the Han Dynasty, the cost of these cloths was very low.

"If that's the case, no problem." Wei Zheng's spirit was shocked, the price of high-grade silk was very high, although there was no way to compare with Mingguang armor, but the difficulty of making the same was much lower.

Xia Zhu also smiled, in fact, things such as high-grade silk and tea will gradually be in demand here in the Han people, in fact, the income of the Han people is very high relative to the price, so many people have savings at home.

As the people have savings at home, the people naturally have higher needs, and clothing, food, housing and transportation will never be left behind, so Dahan also needs to import some more advanced things from Datang.

Of course, because these high-end things are not necessary, the Han still has a trade advantage.

"Then I don't know how much Mingguang armor Datang needs to order?" Xia Zhu asked with a smile.

"At least 10,000 sets!" Wei Zheng took a deep breath and said decisively.

"Since Minister Wei is so happy, then I am also in charge, if Datang orders 20,000 sets, we Dahan can put the repayment time to three years, and allow you to pay it off in three years, and we can give a spearhead for each set of armor."

"Spearhead?" Wei Zheng was a little puzzled.

"Bring something." Xia Zhu turned his head directly and said.

One of Xia Zhu's assistants in the back immediately turned around and went out, and soon they took out a spearhead from the outside box and sent it in.

When this thing was placed on the table, Wei Zheng was stunned for a moment, this thing actually he recognized, it was the head of the gun, just like history is different from romance, Cheng Biting Jin in history used a horse lance, and in romance used an axe.

In fact, most of the generals use horse lance, horse lance is a bit similar to a spear, but there is still a big difference, the main difficulty of making a horse lance is the lance, and it takes nearly three years to make an excellent lance.

But the spear is different, the barrel of the spear is actually a little better wood and tight wood, and the requirements are not so high, so most of the long-range weapons used by the army are almost all spears.

And the one Xia Zhu took out is actually the head of the standard spear of the Tang Army, and you only need to install a wooden pole underneath.

When Wei Zheng picked up this thing, he found that this spear head was different from most of the spear heads in Datang, which were made of stainless steel.

"All steel?" Wei Zheng was stunned for a moment.

"Yes, it's all made of steel, and a pair of armor gives a spear head." Xia Zhu smiled and nodded.

"Deal! Fifteen thousand sets! Wei Zhengyi was excited, and directly agreed, anyway, Li Shimin told him that Mingguang armor could buy as much as he could.

Xia Zhu also smiled, fifteen thousand spear heads, for Datang...... This is a huge amount of steel, but for the big man...... If the cost is strictly calculated, Datang can forge these fifteen thousand spear heads with the money of buying two sets of Mingguang armor.

And Datang bought another 4,998 sets!
