Li Ke traveled by train this time.

First arrived at Chencang by train, and then went to Longzhou Huating, Weizhou (Pingliang), Yuanzhou (Guyuan), Xihui County (Huining), Jincheng (Lanzhou) through Chencang, and this is the basic road.

And cities such as Weizhou and Yuanzhou, according to Li Ke's latest administrative level, he changed the names back to Pingliang and Guyuan.

In fact, the names of Pingliang Guyuan also existed during the Sui Dynasty, but they were changed during the Tang Dynasty, and then Li Ke changed them back.

Highlight a change of day.

This road is the main road from Chang'an to Qinghai, and if you go to Longyou Road, you will go to the direction of Zhongwei.

After arriving in Chencang, Li Ke and the others were also very low-key, although there were five thousand guards, but the guards were not fully armed, at least two-thirds of them were in civilian clothes, as the force of secret guards, and there were only 1,000 guards disguised as caravans.

All the guards did not drive the caravan and so on, but pulled back and forth in a very low-key manner to ensure safety, of course, the most important thing is that this is what Li Ke requested.

After leaving Chen Cang, Li Ke looked at the carriage on the road and felt a little emotional.

Because now the horse-drawn carriages on the road already have iron-wheeled versions of the carriages from the machine-building factory, and there are also steel plate shock absorbers, or leaf springs.

These bonuses have greatly improved the passability of the carriage, and the degree of damage will become very slow, but there are still some problems with the manufacture of tires, and the quality cannot keep up.

Of course, the main thing is compared with the tires of later generations, for this era, the life of these tires is also good, anyway, they have never seen what high-end tires look like.

Tires made entirely of Eucommia, dealing with the problem of technology, the quality is simply not able to keep up, if it is rubber, it will be slightly better, Eucommia is still different from rubber, and the processing technology is slightly more difficult than rubber.

It's nothing for the modern industrial system, but for the industrial system of Datang, the difficulty is not low.

However, the rubber is also fast, according to the news from the origin of the rubber currently planted, the rubber can basically be harvested next year, although the amount of harvest next year is very small, but the amount of rubber used by Datang is not much.

In another two or three years, Datang's rubber will begin to enter the high-yield period, and then tires will gradually become popular.

But aside from these carriages, the official road here is obviously much better than when Li Ke left before, and it has also widened a lot.

At noon, it happened that a service area in front of him appeared in Li Ke's line of sight.

The difference between this service area and later generations is still very big, all the service areas are built on the basis of the nearby post station, right next to the post station.

There is a post station every thirty miles in Datang, and if there are some dangerous official roads, the distance between these post stations will be a little farther. In the Tang Dynasty, the post station only received officials and important court reports, and ordinary caravans were not allowed to enter the post station.

But it is also possible to stay near the post station, especially in some remote places, in fact, most of the post stations will turn a blind eye, and even some places are allowed to enter the post station to rest if you give some money.

Of course, even if you enter the post station, these post stations will be divided into an area in advance and isolated separately.

And this kind of post station is often a relatively remote area, and the imperial court basically turns a blind eye, because most of these places belong to bitter cold places, and the post guards of these post stations are also very hard, and there are some sources of income that can also allow them to support for a longer time.

After the establishment of the service area, it is different, mainly because the service area is also a semi-official version, almost all of the nearby meritorious government soldiers are presided over here, whether it is food and housing, but the living conditions are poor, and the houses in these service areas are built by themselves except for the tents at the beginning.

The Tang Dynasty court gave them monthly money, so for the people in these service areas, this is more like a special village.

Some of them are like the gathering points formed by the establishment of national and provincial highways in many sparsely populated provinces in the northwest in later generations, and some people used to build some houses to provide accommodation and meals for truck drivers.

The current service area is basically like this, within the scope of the official demarcation, in addition to those people designated by Li Ke at the beginning, there are some spontaneous arrivals, so the scale of these service areas has expanded.

But it didn't expand too much, after all, for most of the people, they all had land, and they didn't get to the point where they couldn't live, and they couldn't support so many people here.

Li Ke does not live in a service area, but a post station, which is not a remote place with better conditions.

After staying at the post station, Li Ke changed into ordinary clothes and walked out, and many of Li Ke's personal guards were actually in the service area for a long time.

After all, the service area not far from the post station was full of people, and the guards responsible for covert protection had already stopped here in the form of a caravan.

And when Li Ke came over, he was only accompanied by a dozen or so guards in civilian clothes.

For people like Li Ke, there are often people in this service area, and some gate valve families or wealthy people will always bring some guards when they go out.

After entering a restaurant, Li Ke sat down directly and asked for a pot of tea, and now it was past dinner time, Li Ke asked directly with a smile: "This old brother, I have a few questions I want to consult." ”

The boss was a man in his forties and fifties, with three fingers missing from his right hand and some lameness in his legs.

"Don't you dare to call Lang Jun that, what questions does this Lang Jun have?" The boss said with a smile, as for the guards brought by Li Ke, the boss didn't see it.

"It's just that I came all the way, and I was quite emotional, the official road from Chen Cang to here seems to be a lot wider than when I came here a few years ago, and it seems to have been repaired a lot, do you know who is doing this?" Li Ke asked with a smile.

In the absence of the organization of the official roads in this place, Li Ke really didn't know who was building the roads.

In fact, each county has its own fundraising every year to build roads.

"Haha, Lang Jun, you asked the right person, this is thanks to the kindness of His Royal Highness King Qin of the Tang Dynasty." The boss arched his hand in the direction of Chang'an, and continued happily: "There are people from all directions who contribute to this road, and it can be regarded as the collective contribution of various nearby counties and counties. ”

"Oh? I would like to hear about it. Li Ke said with an interested expression.
