That's right, Zheng Ning already knows the grain output of Dahan, in fact, Zheng Ning and they have been staring at it before the entire grain harvest, just kidding, last year, the surroundings of Yumen Pass were barren, and this year not only opened out more than 100,000 acres of fertile land, but more importantly, those alfalfa grasses are still spreading around.

As long as these alfalfa grasses have grown, they can naturally grow food.

This is a model of the living Gobi Desert turning into fertile land, so Zheng Ning and they have always been concerned about the grain harvest in Huo Gang's situation, because if their grain continues to harvest, they will not have much to sell!

It's so cruel to say, just half a year ago, when they just met, what was Huo Gang's territory at that time? It can be said that there is nothing, everything is lacking, but what about now? How long has it been?

Zheng Ning was a little helpless to find that their Longxi Li family actually had nothing to sell to each other!

To be precise, it's not the Li family in Longxi, it should be said that the entire Datang actually has nothing to sell to the other party! Of course, if you have to say it, that high-grade silk can also be sold, but Zheng Ning knows very well that Huo Gang, the leader, is a very pragmatic leader!

So far, Huo Gang's most glamorous set of clothes is actually his set of armor, can you believe it?! In addition, Huo Gang's other clothes are ordinary clothes made of silk and fine linen.

And these were all the cloths sent by their family master when he came to participate in the opening ceremony of Wanmin Road before, and they were made by the maids they gave to Huo Gang. Most of the time, Huo Gang was wearing these ordinary clothes, if you didn't know in advance, it would be hard for you to imagine that this was the leader of the entire Han Dynasty.

Not to mention Huo Gang's current status, it is that Turkic leaders like Ashye in the past all wore much better clothes than Huo Gang, and even the Yi male leaders of Xue Yantuo's department had clothes that were better than Huo Gang, but they didn't wear them.

Moreover, they originally gave Huo Gang twelve maids, but what are these maids doing now? Almost all of them have been sent by Huo Gang to various important positions, not to mention, and they are also teaching some children and adults to study.

Except for a maid left by his side, but so far, the maid Zheng Ning can see that Huo Gang has not touched her, which means that beauty cannot tempt Huo Gang, from these two points, it shows that Huo Gang is really terrible.

Money, beauty, these can't distract the other party, but what does the other party need?

What the other party needs is something that is useful for the entire territory, but now they don't have it, to be precise, if they want to sell it, they can still sell it, such as the eucommia that the other party keeps purchasing, they can provide it, and the price is also good.

Although they don't know what the other party wants Du Zhong to do, and other things such as chickens and ducks, these things are not difficult for them, but the problem is that these things are not long-term business.

The other party obviously lacks something, just buy what they want, but they can provide it for a long time, and there was food before, but there is no need to ask, after this year, the other party will not be very short of food next year.

This means that there are fewer and fewer transactions between their Longxi Li clan and each other, which is a very dangerous situation.

Zheng Ning has been in business for so many years, if they can only buy each other's products and can't sell them to each other, it will easily become the same as the trade between them and Da Shi, and the other party can price them as much as they want.

This is also one of the reasons why Zheng Ning came to see Huo Gang, mainly to test whether he can buy more goods from Huo Gang's hands, such as glass! Zheng Ning saw this thing when the other party opened the community.

In the past ten days, Zheng Ning has been observing, and almost all the communities on the other side use glass as windows, which means that the output of these glasses is very high. Since the production is high, there is a possibility of selling!

Zheng Ning went to Zhao Er's house as a guest, and this glass is really ...... Zheng Ning didn't know how to describe it, he never thought that there would be such a bright time in the house! Especially the large area of glass used by the other party, during the day, the whole room is extremely bright.

If it is transported to Chang'an, do you believe that those nobles in Chang'an are willing to change even if they change a window dozens of times? ! Speaking of this, what made Zheng Ning a little speechless was that the windows of Huo Gang's general's mansion had not been replaced with glass.

It's not that they don't change it for Huo Gang, but Zheng Ning heard that Huo Gang is said to want to build a new palace by himself, not this traditional form of palace, it is a brand new palace built with that kind of concrete, Zheng Ning doesn't know what it looks like, anyway, I heard Zhao Er boast, saying that the leader of Huo Gang said that it is definitely much more luxurious than their Taiji Palace!

It is not clear whether there is a luxury in Taiji Palace Zheng Ning, because he has never been to Taiji Palace, and he has never even seen what it looks like inside, but Huo Gang is here, he believes that one day he will have the opportunity to see it.

When Zheng Ning was thinking nonsense, Huo Zheng's voice over there had already come: "Shopkeeper Zheng, the leader is invited." ”

"Thank you, General Huo." Zheng Ning arched his hand at Huo Zheng.

Entering the living room, Zheng Ning immediately saluted Huo Gang respectfully: "I've seen the leader." ”

"You're welcome, shopkeeper Zheng, please take a seat." Huo Gang pointed to the position next to him and said.

Zheng Ning was not polite, he simply sat down directly, he knew that Huo Gang was different from other leaders, and on a daily basis, he had never seen a leader more approachable than Huo Gang.

After sitting down, Zheng Ning also praised this chair in his heart, this chair was also invented by Huo Gang, after Huo Gang invented it, since his own head of the family sat back in Dunhuang, this chair instantly spread throughout Guazhou and Liangzhou, it is said that Chang'an City has already begun to make chairs.

This is indeed much more comfortable to sit on than the previous stool, and it is also more convenient than the previous couch, and it is more comfortable than kneeling there.

"Chief, Zheng doesn't dare to bother the leader too much, I'll have something to say, chief, I don't know if we can have the opportunity to sell glass to the territory of Datang." Zheng Ning was also polite, and asked directly.

Regarding Zheng Ning's inquiry, Huo Gang was not surprised, because after the appearance of such a thing as glass, the people of the Li clan in Longxi who entered and exited Yumen Pass every day could not see that there was a ghost, and they would have to come over to inquire sooner or later.

In fact, Huo Gang is not prepared to hide this thing from the outside world, even if the finished product of this thing is sold, if you don't know the process, you still can't make it, so Huo Gang is not afraid, the probability of leaking its production formula is even lower than that of cement.

Of course, it is also difficult to reverse the cement in this era, because if they do not have a systematic chemical industry, they want to analyze what is in it, at least not in a short time.

After waiting for a few years or more than ten years, at that time, Huo Gang may not be able to sell cement openly, of course, it is estimated that it is unlikely to be sold openly, because for a long time, cement is not enough for Huo Gang, just to build roads, I don't know how much cement is needed, not to mention various construction tasks.

On the other hand, glass can be sold to Datang after the first wave of sales, and the important thing is that it can be exchanged for a large amount of money back.

"Yes, but not this year, the production of glass this year can't keep up." Huo Gang shook his head very dryly and said. Now the output of glass has been very large, mainly because the speed of glass firing is actually faster than that of steel, and the technology of glass blowing is actually not difficult.

As long as you have a mold on the outside, anyone can blow out a nice piece of glass.

Therefore, the production speed of glass is not slow at all, of course, it is much slower than cement, but the demand for glass is not so big for the time being, and the main role of glass is windows.

After winter, Huo Gang may let them start to study convex lenses and concave lenses, whether it is a magnifying glass, a telescope, or a more advanced microscope, they can actually be produced.

Microscopes, in particular, are very important for the study of chemistry and physics, and you can't just describe them, there are some things that you have to let them see.

"Thank you, Chief, and Chief, our head of the family asked me to ask, what is the carriage...... Can't you really sell it? Zheng Ning asked a second question.

The carriage in Zheng Ningzui's mouth is naturally made by the Industrial City, using steel wheels, steel axles and steel plate shock absorbers.

If this kind of carriage is replaced, the better official road means that their pack horses can walk 50 kilometers a day without any problems.

This speed is not a star and a half higher than before, especially since the previous carriage was often damaged on the road.

"I guess not for the time being." Huo Gang thought about it, but still refused. "To be precise, I sold it to you, and the price is too high for you to afford, but if the price is too low, you will divert the steel on it for other purposes."

Huo Gang also said very bluntly, "However, I have a compromise solution." ”

"What's the solution?" Zheng Ning was immediately shocked.

"We're going to set up our first shipping company soon, and they'll be responsible for all kinds of delivery tasks, and you can hire them to deliver your goods for you, and the freight will definitely satisfy you." Huo Gang gave a new way.

"Shipping? This...... What should I do in Datang? Zheng Ning hesitated.

"Our people can send it over, too." Huo Gang said with a smile.
