Speaking of the city wall, we have to talk about the location of the Yumen Pass, the ancients also have a scientific basis for the location of these gates, in fact, as long as you know some geographical structures, you will know that most of the Gobi Desert was originally similar to the terrain of stones, and then gradually weathered and finally became the Gobi Desert.

The soil layer on the Gobi Desert is not too thick, of course, the soil layer in most parts of the entire earth is not very thick, and here in Yumen Pass, in fact, the city wall is ready to dig a three-meter-deep foundation, but in many places the rock has been dug without digging three meters at all.

The entire castle is covered with rock formations, so there is no need to worry about the foundation of the castle wall.

In Yumen Pass, it is getting closer and closer to perfection, and the news of the official opening of Yumen Pass has caused a great sensation around, not only in Datang, but also in the surrounding Yanqi, Gaochang and other countries, but the reason why it has caused a sensation in these countries is that there are many merchants from Dashi here.

That is, the merchants of the Sassanid Dynasty, you must know that the merchants who were active on the Silk Road, these merchants from the West such as Dashi were more numerous than the merchants of the Tang Dynasty, and the same more wealth was transported by them.

And this kind of news not only made everyone in the entire Yumen Pass excited, but even the entire Datang Dunhuang County, Suoyang City, Guazhou City, Yumen Pass and other cities close to the Han Dynasty also began to become excited.

Especially Dunhuang City, Dunhuang City has Longxi Li's Dunhuang House and other gate valve families, the same number of other merchants is also a lot, if it was before, although Dunhuang is also very prosperous, but it is not so prosperous now, because all the inns in Dunhuang have been full.

Everyone is waiting for the day when Yumen Pass is officially opened to the public, although Yumen Pass has never said that outsiders are not allowed to come, but in the past, only the caravan of the Li family in Longxi could go to Yumen Pass, and the number of caravans of other gate valve families was very small.

Li Yi actually knew the situation at Yumen Pass, but since Li Shimin's accident, the Li family's caravan in Longxi has also suspended trade to Yumen Pass, and the previous goods have been stored, so it is nothing to say that trade will be temporarily suspended.

They didn't quite know what Yumen Pass was like now, and since the other party had already passed on the information, saying that after the envoys of the Tang Dynasty arrived here, Yumen Pass would be officially opened, so they simply waited for that point in time.

Wei Zheng looked at the scenery of Dunhuang County, his spirit was somewhat trance-like, and the other Wei Zheng didn't know, but along the way, Wei Zheng saw the prosperity of the entire official road, and there were many deserted places before, but now there are many houses on both sides of the official road.

Wei Zheng has already sent someone to ask, these places are not built by others, but some displaced people, landless people rely on the official road here to barely survive, they can only provide some hot water for the merchants who come and go, and after slowly earning a little money, they can buy grain to provide some food and hot water for these merchants on the official road.

Just like the family that Wei Zheng asked, their family also suffered a disaster, and then fled all the way, they were also a coincidence, in order to build a shed next to the official road for safety, just a few caravans came over during the day, asked them to ask for water to drink, plus their men have a little hunting skills, and two hares were also exchanged for grain by the caravan.

So they survived there, at first relying on the prey they brought and providing these caravans with tea, food, etc., and in half a year, they hired someone to build a courtyard next to the official road, and now even lodging can be provided for the caravan.

Later, a few more families seemed to see this, and built houses next to them, and slowly, now there were more than a dozen families in their place, and they had become a place where caravans could pass and rest.

Including Wei Zheng, they all chose to rest there when they were resting, you must know that in the past, there were no people in a radius of dozens of miles.

And there are many examples like this, although others may not be like this family is homeless, but they even encountered a small village on the way, and the whole village was relocated to both sides of the official road, and the caravans of these official roads were fed, etc., and the whole village was getting better and better.

According to them, they used to be very poor.

This road is close to 3,000 miles, and this official road feeds more than a few villages? Even many cities in the middle of the official road began to become prosperous, Wei Zheng specially asked the county officials who passed by some county seats, and from the mouths of these county officials, Wei Zheng knew that with the caravan increasing several times compared to before, it can be said that the income of all the people in the entire county has increased a lot at once.

Even some wealthy people took the initiative to repair some roads in order to do better business.

When Wei Zhenghui and Gao Shilian rushed to this Dunhuang County, Wei Zheng's whole heart could be said to have suffered a great impact, what is Liangzhou? Although there was a Silk Road in the past, according to the reports of officials at all levels in Liangzhou, Liangzhou is not a rich place, this Western Regions is a bitter cold land, and the people everywhere often have droughts, locust plagues, and famines almost every year.

Although Wei Zheng is a minister, he is also in charge, and he knows that Liangzhou Guazhou needs some food support from Guannai every year, but the amount of food supported is not much.

But what about now? Along the way, this official road has affected at least hundreds of thousands of people!

You know, the more people are supported by the official road, the fewer people will need the surrounding land.

Wei Zheng's investigation was very clear, the caravans on the road were very prosperous, but these caravans were not completely trade with the Han caravans, according to his conversations with some caravans, some caravans were actually transporting salt, grain and other materials from the customs to Guazhou, Liangzhou and other small cities.

Because the people in these cities made money because of the official road, they could buy grain, salt, and some iron tools, and these things were originally lacking in these places in Liangzhou, so many people transported them from the customs to sell!

In this way, this business path becomes more prosperous!

It's as if the transaction between the Li clan in Longxi, as well as the various gate valve families and the Han Dynasty, was a leader, and then completely drove the land of the two continents and made them start to prosper, is this the role of commerce?

It seems that what His Majesty talked about with Huo Gang about increasing commercial taxes is indeed correct! It seems that since ancient times, the matter of business taxes has indeed been underestimated by these people, Wei Zheng suddenly understood what Du Ruhui scolded him.

Yes, they should take a look, look at the lives of these people at the bottom, see what they need.

Is Li Shimin competing with the people for profit, or is he making decisions for the people? is like Du Ruhui's words, these rich people, gate valve families, they are fart people? They are all of the noble class, and they are considered the aristocratic class of this country.

"Brother Shilian, this time the affairs of the envoy group still depend on you." Wei Zheng said in a serious tone to Gao Shilian next to him.

Gao Shilian looked at Wei Zheng, his expression was somewhat weird, to be honest, Gao Shilian didn't expect Wei Zheng to come at all, and after Wei Zheng came, the attitude along the way was completely different from the Wei Zheng he knew.

Gao Shilian is older than Wei Zheng, so Wei Zheng's brother, Gao Shilian can also afford it.

"Xuan Cheng is polite, this is what you and I should do, and Your Majesty also makes you and me responsible." Gao Shilian smiled and spoke.

"To be honest, I'm really curious about Huo Gang now, I can't imagine what kind of person is who can change so many people around me in such a short period of time!" Wei Zheng looked at the distance with some emotion and said.

"Haha, we'll find out in two days. It is said that many of the buildings in Yumen Pass have been completed, and to be honest, I also want to see it, knowing that the previous Yumen Pass is still in ruins. I inquired with people, and at the beginning of this year, the entire Yumen Pass was covered with yellow sand, almost half of the city walls had collapsed, and there was nothing left of the buildings in the city. Gao Shilian laughed twice and said.

It is definitely impossible for him and Li Shimin to go to Yumen Pass and see Huo Gang, so he is also a person who has "not" been to Yumen Pass.

However, although he has actually been to Yumen Pass, Gao Shilian is actually still very curious about Yumen Pass, he was in a hurry last time, and he didn't have time to observe many things at all, but this time it was different, they were envoys this time, and they could observe Yumen Pass openly.

"Well, and their cement, I don't know how amazing it is, it is said that the road they paved is the same as that paved with bluestone slabs." Wei Zheng nodded with some curiosity.

"I can testify to this, tomorrow Xuancheng you can see it, from the west gate of Dunhuang County all the way to the cement road of Yumen Pass, speaking of which, if Xuancheng wants to go to see, you can do it now." Gao Shilian said.

"No, we're not going to be in the ...... they say tomorrow Is that service area closed? Tomorrow we have time to see. "Wei Zheng is not in a hurry.

Gao Shilian smiled, he knew why Wei Zheng didn't go, because Wei Zheng was an envoy, so he still had to pay attention to some of his own image, because they now represented the Tang Dynasty. Although it is said that the Tang Dynasty and the Han Dynasty have become good friends of the Qin and Jin Dynasties, they are still two countries.

Dunhuang County is not very far from Yumen Pass, but they brought a lot of gifts and so on, so it will take at least two days to walk to Yumen Pass.
