For the two of them, Huo Gang naturally doesn't care, so much food in Dahan can't be consumed, of course, if there is more food, it is also useful, that is, the official grain and oil firm of Dahan will make strategic adjustments, such as planting different crops, these crops are used to extract oil, or to produce other foods, it is okay, such as beans.

In addition, in the Tarim River Basin, that is, some areas around the Tarim Basin, large-scale trial cotton planting has begun. The Xinjiang long-staple cotton in later generations is the world's top cotton, so it should be able to be cultivated here now, and the genetic optimization ability of Lingquan water is stronger.

For these crops and crops, the effect is naturally stronger, in addition to the Tarim Basin, as the largest desert in later generations, the current area of the Taklamakan Desert is actually not as large as in later generations, one of the main reasons is that the Tarim River almost surrounds the entire desert.

And because after becoming spiritual spring water, the expansion of these deserts has been curbed, although the area has shrunk almost equally, but after being contained, almost all of them have gradually become fertile fields within the scope of containment.

In particular, after the continuous improvement of alfalfa grass, it will be fertile land in a few years, and I am afraid that future generations will not be able to imagine that this place can become a huge grain production area, but if it really becomes a grain production area, the area here is ...... I'm afraid it's far more than many people think.

You must know that the area of the North China Plain in later generations was only about 310,000 square kilometers, the Northeast Plain was about 350,000 square kilometers, the middle and lower reaches of the Yangtze River Plain was 160,000 square kilometers, and the Guanzhong Plain was about 60,000 square kilometers, adding up to about 880,000 square kilometers.

According to the calculation that the domestic grain production in later generations was about 1.3 trillion catties, it is conceivable how much these lands can produce and plant.

And how much does the area of the Tarim River add up to the Huo Ci River and the Huo Ci Sea? The total basin area is approximately 1.4 million square kilometres, with a focus on these basins...... Most of them can almost be said to be plains, with the blessing of spiritual spring water, the fertility of these lands is comparable to the black soil of the northeast, and what is even more terrifying is that with the passivity of the spirit of Yumen, there are almost no natural disasters.

This means that 50% of the land in these places is cultivated land, and there are more than 700,000 square kilometers of terrifying area, not to mention that these 700,000 square kilometers are all comparable to black soil? In fact, far more than 50% of the watershed area in these places is actually used, but most of the remaining area has been converted into pasture for farming.

Because of the increase in precipitation in the entire Dahan region, the pastures in many places have gradually become abundant, although these places are not excellent pastures such as alfalfa grass, but there is no problem with free-range breeding, and the winter pasture grass can be mobilized from other places.

Don't forget, all this does not count the Ganges River field that newly joined the Han Dynasty, as the world's largest rice exporter in later generations, although India said that there are a lot of people who can't eat enough, but these are enough to prove how rich India's Ganges River Basin is, with the passivity of the spirit of Yumen, the grain output in these places is definitely not less than the Huoci River Basin, not to mention the Putuo River Basin.

In fact, there are too many places where Dahan can grow grain in the future, so there is no shortage of food in Dahan, not only food, but also all cash crops and so on, which are all foreseeable.

The only pity is that there are a lot of high-yield crops in Dahan now, such as corn, sweet potatoes, these crops, fortunately potatoes have been made out by Huo Gang, I have to say, potatoes are the real artifact, potatoes have become one of the indispensable foods in all the people of Dahan.

And some of the potatoes have begun to flow into Datang, it's not that Huo Gang doesn't want to control it, the main thing is that after too much, it is almost impossible to control it, so Huo Gang didn't control it, but directly began to export a large number of them.

How to say this thing, once the export is increased, the ordinary people of Datang are not willing to plant, and if they have a seed, the most they can do is to plant one or two points of land for their own family, and then eat it themselves, because there is no shortage of food now, and their land is more valuable to grow cash crops and can buy more grain, and potatoes are even less valuable.

They grow their own losses, but for the people, even if these things are cheaper to buy, they will grow some of them and eat them daily, because it is not easy to buy vegetables and the like in modern rural areas in later generations, let alone this era, so they all have to grow some of their own food, but many people choose not to plant food.

Because there are many grain merchants who transport grain directly, and they all grasp the hearts of the people, basically in the spring, they can buy grain, and it is the kind that can be bought for a year.

The reason why these grain merchants chose this way is because they can hardly make money from the grain in the cities, and they can make some profits by selling grain in the countryside, mainly because they have to buy some of the cash crops planted by these people at the same time, and this is the key.

Profits are also meat in small sizes.

"Food is fine, armor is fine." Huo Gang thought about it and didn't refuse, the steel output is still not enough for Dahan, but for Dahan's current steel production, the steel used to make these armors no longer affects the overall situation.

"This armor...... What did you just say look like? Li Shimin next to him really couldn't hold back, this kid came as soon as he opened his mouth, he could provide it to his son, although Datang bought tens of thousands of sets of Mingguang armor, but there are many soldiers in Datang, and there are more armor, so they naturally don't care.

"That's right." Huo Gang thought about it, and simply ordered Chang Lin, and then asked him to go to Li Zhi and bring over a cavalry doll he gave to Li Zhi.

That's right, Huo Gang also gave Li Zhi some toys, and there were cavalry dolls similar to the figurines of later generations, which were quite realistic, and there were exactly what Huo Gang needed.

Chang Lin quickly took the order and left, his speed was also very fast, and he came back in less than twenty minutes, looking at the palm-sized cavalry model placed on the table, Huo Gang directly took down the cavalry above, pointed to the armor on the cavalry and said: "Actually, it is similar to this, I call it plate armor." ”

That's right, what Huo Gang took out was plate armor, because of the armor protection ability of Mingguang armor, although the protective area is very strong, especially with the steel technology that Dahan has now made, which is far beyond the armor of this era, the protective ability is far beyond the armor of this era.

But whether it is Mingguang armor, piercing armor, or scale armor, it is too cumbersome, those armor pieces and so on are very simple to make for the Han, and the plate armor in this era actually surpasses the Mingguang armor, whether it is to deal with arrows, or chopping, etc., the protection ability of plate armor made by direct forging and stamping is definitely much stronger than that of Mingguang armor in terms of protective arrows, chopping, stabbing and other aspects.

The only drawback may be that the protective area has decreased slightly, after all, Huo Gang is to make it fast and easy to make, and it is impossible to make any full-body plate armor, and the practicality of that thing is not high, so he makes half-body plate armor. The protection on the arm is also made up of a combination of curved steel sheets.

The legs and other places are also protective thighs and key areas above, and other places are basically in an unprotected state, but this is completely enough for the era of cold weapons, in fact, whether it is plate armor or Mingguang armor for this era, it is a bit over-protective, except for the big Han, other countries have almost no ability to fight against these armors.

It's just that the Mingguang armor is more comfortable and flexible, but in fact, except for the Mingguang armor of the Han Dynasty because it is made of special alloys, Huo Gang doesn't know what alloy it is, and the weight of the Mingguang armor sold to other countries is actually more than that of plate armor.

So the advantage of plate armor is still very big, of course, the biggest advantage is that the big man makes it fast! This thing is directly stamped and formed in one piece, with fast manufacturing speed, fast combination speed and simple maintenance.

"It's all made of steel?" Li Shimin's eyes widened.

"Yes, made of stainless steel." Huo Gang nodded.

"What about the price?" Li Shimin couldn't help but speak.

"The price is cheaper than Mingguang armor." Huo Gang thought about it, but still said, "And it's a lot cheaper." ”

"How much?" Li Shimin looked at Huo Gang and asked.

"Cost price, how about 200 guan?" Huo Gang said a number that made him "weak-hearted". The price profit that Dahan sold to the other party was too high, and it was sold according to a set of 490 guan, and the cost price was about 8 guan.

And the cost price of this plate armor ...... It's only about 4 times.

"Cheaper, I know you're still profitable." Looking at Huo Gang's expression, Li Shimin couldn't help but subconsciously speak.

"That's ...... That 150 runs. Huo Gang immediately added. If you run a set of 150, then the profit is about, about 40 times?

Hearing that Huo Gang cut the price so simply, Li Shimin immediately guessed that Huo Gang's profit here was definitely not low, "If it drops a little more, you also know that although Datang is rich, it is not so rich." ”

Huo Gang began to ponder, to be honest, 40 times the profit, put it in the future...... There are hardly many legitimate businesses with such high profits, but in this era, Huo Gang can do it, but if it is at this price, the number that Datang buys will not be too much.

He was wondering, is it necessary to reduce the price appropriately to arm the Datang people, if the price is lowered to arm the Datang people, although it seems that Huo Gang's profits are low, but in fact, the armed Datang people will quickly take over the surrounding small countries, which means expanding the market of the Dahan!

And it will also bring a large number of follow-up markets, it is foreseeable that the land laid by Datang is the market of Dahan! And besides weapons, something else...... That's really high profits, for example...... Glass.

Thinking of this, Huo Gang made a decision, he directly raised his head and looked at Li Shimin and Li Tai and said: "In this way, I won't negotiate the price one by one, just like the transaction between us and Datang before, if Datang buys 20,000 sets, I can give you a minimum of 120 sets at this price, if Datang buys 50,000 sets, I can reduce this price to 100 sets, if I buy 100,000 sets, I can lower the price to 80 sets." ”

Huo Gang directly lowered the price to a certain point, although this price still has a profit of nearly 20 times for Dahan...... But he can't cut the price too ruthlessly, because the price reduction is too ruthless, Datang, who has just paid off the arrears of the Han, only bought 20,000 sets for 4.9 million yuan before.

Now 8 million guan can buy 100,000 sets! If the price is reduced again, it will make the other party unbalanced.

Of course, this is also because of the technological progress of Dahan, and Huo Gang believes that they are understandable.

"Really?!" Li Shimin almost stood up from his position excitedly, 100,000 sets, only 8 million? If it was the first year of Zhenguan, don't say 8 million, even if it was 800,000, he would hesitate, but who made Datang stand up now, Datang's treasury is full, and Li Shimin doesn't care about 8 million guan.

"Seriously." Huo Gang said very simply.

"Send matching weapons, the ones you gave when you bought them last time." Li Shimin took a deep breath, looked at Huo Gang and said, "I'll ask for 100,000 sets." ”

"Okay, send!" Huo Gang pondered for a while and agreed, the long knife and the spear head are actually nothing more than a casting problem, for the big han, these two things don't use much steel, and the big man sells these things now, in fact, the construction cost is almost nothing, it's just the price of the steel itself.

"Deal, 100,000 sets, I want it from Datang, how long can you deliver." Li Shimin said decisively.

"Deliveries will be completed by the end of this year." Huo Gang simply gave a number.

"Okay, I'll ask Ambassador Liu to come over later, so that people can officially sign the purchase contract with Dahan." Li Shimin took a deep breath, "But if the money is according to the previous payment method, will it work?" Is it paid for the goods, or is it paid over three years? ”

"Yes, it will be paid in three years with interest." Huo Gang can't always take out interest-free loans.

"8.8 million." Li Shimin directly gave 10% interest.

"Okay." Huo Gang simply agreed, "Since this is said, then let's talk about other things, by the way." Since he talked about this, Huo Gang thought about it, and simply talked about the cement matter.

The cement was opened to Datang, Huo Gang had already thought it through, because cement was no threat to Dahan, and no matter how strong the city wall was, it was in vain in the face of artillery, so it was natural to provide it to Datang, and once cement was opened to Datang, it meant that there were more goods to sell to Datang.

Next, steel products can also be sold to Datang, building reinforced concrete, they always have to import steel, the price of these steel is not as good as weapons, and the profits are not so high, but the profits are also not low, this is an incomparably huge market.
