In the middle of chatting with Feng Gui, a group of buildings appeared in the distance ahead.

"Look, that's what I told you about." Feng Gui pointed to a circle of buildings in the distance and said.

Li Ji immediately looked there, there was still some distance away from them, but he could see that there were at least dozens of felt tents there, and they were next to the side of the road, and there was a small forest around the felt tents, about a dozen trees.

However, it seems to be fenced off with something on the perimeter.

"What's that fenced off?"

"It's a fence made of wood and weeds to prevent wind and sand, Feng Yuan said, when the road is repaired, a better brick wall will be built here, and I don't know about this." Feng Gui shook his head.

In this way, the post station in the distance is getting closer and closer, and when it gets closer, Li Ji sees that this post station is connected to the road, but on the right side of the road, a large piece of land has been leveled, and at the entrance of the post station, there is also a wooden sign with a few words written on it: Shahe Post Station.

"Is this Sand River the name of the place?" Li Ji was a little curious.

"Yes, the Shahe River is about three miles away from here, it is a small river, and it is also the main source of water here." Feng Gui nodded, and as he said, he had already jumped out of the carriage, and then drove the carriage towards a felt tent.

The area of this post station is not small, and Li Ji saw that the felt tent planning here is also extremely regular, divided into six or seven areas, and there are neat horse piles standing in the entire post station, and the carriages are neatly tied to these horse piles.

Their convoy also quickly arrived in front of several felt tents, and from a long distance, Feng Gui had already shouted out laughing: "Big brother." ”

"Ah, brother, you're here." Inside the felt tent, a Turkic man with gray hair who looked much older than Feng Gui, but who looked quite sturdy, also laughed a few times, and spoke in a somewhat accented, but very proficient Chinese.

Feng Gui hugged the Turkic man named Feng Yuan directly, "Brother, each person has a bowl of milk tea, there are a total of eighteen of us, and some jerky." ”

"Haha, okay, I'll invite you this time." Feng Yuan laughed directly and said.

"That's not good, brother, you stay here for a year, just earn such a little hard-earned money, brother, I still earn more than you." Feng Gui said quickly.

"Okay, I won't fight with you, then I'll bring some tea next time."

"Hehe, I'll bring it to you this time." Feng Gui walked directly to the side of the carriage, and then took out a large bag of tea leaves and handed it to Feng Yuan, it was not a good tea, it was just the end of some black tea, but it was already good to be able to drink tea in this Western Regions, let alone milk tea.

Li Ji and the others were all sitting here, and there was a Turkic woman laughing and busy, just two Turks, they quickly used a big iron kettle to pour a bowl of milk tea on the table in front of them, and Li Ji naturally poured a bowl in front of him.

This milk tea is to put the black tea powder into the iron kettle and boil it with the milk mixed with water, there is a milk fragrance, this milk is goat's milk, but there is not much to put in, but in this Gobi Desert, drinking hot water is a luxury, and it is good to have milk tea to drink.

Li Ji took a sip of milk tea, it tasted very good, he noticed that the guys of these caravans had taken out the dry food, and started to eat it directly with the milk tea, Li Ji also took out the dry food he prepared, he didn't prepare any special dry food, just dry pancakes, just dry flour in the pot.

If you eat such a cake dry, it will naturally be difficult to swallow, but if there is milk tea at the moment, it is not bad.

"Come on, come on, my brother will introduce you to someone, this is a brother I met on the road, named Li Wu, the fifth in the family, you just call him Wulang." Soon, Feng Gui pulled Feng Yuan over to give Li Ji an introduction.

"Thank you, big brother, for your hospitality." Li Ji immediately clenched his fists and said.

"Oh, Gorou is polite, you all paid for it, paid for it." Feng Yuan smiled honestly and waved his hand and said.

"Big brother, what are you talking about, we used to be on this road, but there is nowhere to buy it with money." Feng Gui said directly.

"It's all the credit of the leader, if it weren't for the leader, we wouldn't be able to live such a good life." Feng Yuan immediately laughed.

That's right. But brother, when I came, I saw that the road had been repaired to the Yumen Pass, will it be repaired to our Datang Yumen Pass in the future? Feng Gui sat down at the table and asked with a smile.

"That's unlikely, hasn't the leader already built the road outside Dunhuang County? After this road has been to Dunhuang County, it is said that the road from our Yumen Pass to our Yangguan side is about to open to traffic, and when the cement road is repaired to this Yiwu City, this road will be better. Feng Yuan said with a smile.

"Anyway, brother, you've said this cement road several times, and now this road is already very good, much better than many official roads in Datang, how good can this cement road be?!" Feng Gui asked curiously.

Li Ji immediately pricked up his ears, this thing is all important information.

"You know what! Hahaha, this cement road was brought down from the sky by Leader Huo, after it is built, the road surface will be as hard as a stone, and now this road surface will be damaged to some extent, but that road, your carriage will not be crushed at all! And even if it rains or snows, the road surface will be clean in no time! Your carriage is much faster! Feng Yuan immediately said with a smug smile, as if the road was taken out by him.

"That's amazing." Feng Gui said with some surprise, "How can this be turned into stone, it's really unimaginable. ”

"You'll know when the time comes, and I'd love to see the roads in front of me get better." Feng Yuan said with a smile, "In this way, this thing will be transported faster." ”

And Li Ji was instantly vigilant, this cement, if it really has such an effect, then since it can be used to build roads, it means that the quantity produced by the other party is huge, so if you can build roads, you can build city walls!

Of course, although Li Ji didn't know what this cement was, it was obviously something they needed to pay attention to.

Li Ji remembered this name directly in his heart, but Li Ji did not dwell on this question, but continued to ask curiously: "Big brother, I see that pits have been dug more than ten meters away from both sides of the road, I don't know what is particular about these pits?" ”

"Hey, those pits, they will be used to plant trees in the future, the general said, if trees are planted on both sides of the road, they can be used to prevent wind and sand!" Feng Yuan waved his hand.

Planting trees? Li Ji was stunned, he thought of all kinds of answers, but he just didn't expect that there would be an answer to planting trees.

This...... No one in this era will realize the role of planting trees, even in the Central Plains, no one has planted trees, let alone in the Gobi Desert in the Western Regions, and Li Ji is incredible.

Because in this Gobi Desert, I want to plant trees alive, which ...... How much does it cost? Could it be that this Huo Gang has a lot of money and has no place to spend it? Planting trees in these places?

But Li Ji naturally wouldn't say this.

Of course, what Li Ji didn't know was that Huo Gang had such an artifact as spiritual spring water, whether he planted trees or raised seedlings, soaked these in spiritual spring water for a day or two in advance, and then watered spiritual spring water, these saplings could almost be said to be 100% alive.

And when these forests form a forest belt on the Gobi Desert, it is of great help to block the enemy's sight, and it can also become a marker on the grassland, just like Ao Bao.

In fact, the prototype of Ao Bao has appeared in this period, and the Ao Bao of this era does not seem to have the meaning of sacrifice in later generations, and Ao Bao is used as a signpost on the grassland in this period.

Because of the vast grassland, it is easy to get lost in many places without road signs, and when these forest belts are built, it will naturally be easy to recognize the road.

And there is another point, under these forest belts, Huo Gang will level a new dirt road and grass, these grass and dirt roads will be checked, this road is different from the cement road is used for cavalry transfer.

Because if the war horse with a horseshoe runs wild on the cement road, it will cause great damage to the horse's legs and hooves.

As for the pack horses that pull heavy loads, it doesn't matter, as long as they don't run wildly, plus the cement pavement Huo Gang will not be so smooth, because the paws of the horses pulling the cart are easy to slip, so these cement pavements will go through some simple treatment.

In fact, there is nothing to deal with, that is, the concrete is directly dried and maintained, unlike some cement pavement, and the top is smoothed with a layer of plain cement.

Feng Gui and the others didn't sit for too long, and after eating lunch and resting for a while, the caravan was on the road again, but when they left, Li Ji paid the money for milk tea at noon, two bowls of milk tea for a penny, and bought a little jerky and dry food.

Feng Gui didn't fight with Li Ji, he also knew that he had paid Li Ji the toll before, and Li Ji reciprocated Li Ji and regarded Li Ji as a friend, so Feng Gui accepted it with a smile. Leaving the post station, Li Ji did not say goodbye to Feng Gui immediately, but followed Feng Gui's caravan to the evening.

When they came to the evening, Li Ji found that another post station appeared in front of them, this post station was called Baishan Post Station, named because there was a mountain with many white stones nearby.

And Li Ji also discovered the law of these post stations, Huo Gang's people obviously calculated that there would be a post station about every half a day! Just enough time for these caravans to rest. Sure enough, as soon as Li Ji asked Feng Gui, he was sure of this matter, and it was indeed the case, every half a day, there happened to be a post station for these caravans to rest.
