In fact, Lin Shan asked Ma An to drive around Wushiling in the north of the county seat, mainly to avoid the deans of the two academies and the enthusiastic students who might come to see him off. Lin Shan's request to Dean Lizheng was indeed a little difficult to say directly. And if a group of students came to see off the academy, he would be tired of spreading the lie of leaving several more times.

Once the rhetoric of storytelling is mass-produced, it is not as easy as telling the truth.

However, named after the color of the land, Wushiling is a series of mountains that have the characteristics of continuous and vast terrain, but there are no great peaks among the mountains. After rounding half of the mountain, the carriage turned into a sandwich road that crossed the mountains, and then drove into the official road leading from the county seat to the neighboring county. And the time delay caused by this detour is not much wasted time for the entire trip to Beijing.

After passing through the official road that connects the counties, entering Yang-gun, which is located northeast of the county seat, and then heading from Yang-gun to Kyoto, there are many more routes to choose from than the prefecture behind you.

When the presidents of the two courts met in the official road of the county seat, Lin Shan took a carriage to avoid that section of the road, and it was already out of the geographical scope of the county seat. At noon, the carriage had entered the city of Yangjun, replenished some water and food, and after a short rest, the carriage traveled on the official road connecting Yangjun to the east of the capital.

Yedu was once the imperial capital of the former Zhou Dynasty, and Zhou Tianzi stayed in this city for nearly 300 years, and it was not until more than 40 years ago that Zhou Tianzi moved the capital to Huyang. Later, Zhou overbuilt Zhaojian, and the new emperor did not move the capital back to this old capital. But in fact, the building facilities built by Yedu under the accumulation of imperial power for hundreds of years are far more sophisticated and perfect than the new royal capital Huyang.

Just saying that the official road leading to the four surrounding counties can be called a model of official road in the country. The founding monarch of the former Zhou Dynasty was well aware of the importance of the smooth passage of the road to the country, so he consolidated the capital city tower while heavy industry. For the construction of the four official roads in the four neighboring counties of the city, the workers sent were all separated from the team that repaired the city tower.

These four official roads use the method of pouring and casting roads, including the military industry, and civilian use of their tables. After the road surface is solidified, ordinary laborers dig more than a dozen times with chisel axes, and only a small hole will be exposed on the road surface. This wide official road allowed five horse-drawn carriages to run in parallel. The whole country is not stingy in peacetime for the use of the people. In wartime, it was used to transport military quarters and march brigades.

Therefore, when Ma An drove up this trump card official road, he almost took out the speed of a rapid march, and the skills he had practiced in his past military career were completely released at this moment. And the bloodline comes from the great hurricane of the nobility among the military horses. When the iron hooves hit the surface of this wide road, the feeling of the shock back seemed to touch its temper that had been suppressed for many years, with the whip of Ma An. Then he let go of the four hooves.

Mo Ye, who was sitting in the car, felt the body of the car shake, she lifted the curtain and looked out, and couldn't help but feel slightly surprised in her heart. She had never seen Ma An drive so frantically she was a little worried. If you run like this, will the wheels fly out later?

She was obviously a little worried about this idea, and the carriage had been moving at this speed for nearly half an hour, and there was nothing unusual about the wheels. It's just that the horse lives for a year, which is about three years old, so the horse has entered the end of middle age and is really old. In addition, I have not had the opportunity to run like this for many years, and my endurance and footwork have regressed. After running so suddenly for about an hour, it finally slowed down.

Of course, Ma An knew the bottom line of the horses he tended, so after he was happy, he saw that the horse's pace slowed down, and he didn't rush to whip it anymore, so he let it go so slowly. However, this natural slowing down was only relative to the rapid march just now, and if the usual speed was taken as a reference, the carriage was still moving much faster than usual.

When the former Zhou monarch presided over the construction of these official roads issued by the imperial capital, these four words were hidden in the main theme. In detail, it is how to make the fastest march speed to enhance the mobility of the army, and how to get the maximum amount of military supplies at the same time and on the same route, and how the former Zhou monarch asked his subordinate sappers to build roads.

And the road built with this theme inadvertently sought the greatest benefit for business travel when the country was in peace.

After the previous Zhou moved the capital to Huyang more than 40 years ago, the commercial nature of the old imperial capital became more and more obvious. After the change of dynasty, the new monarch of Zhao did not exclude the merchant travel, an integral part of the people, but took great care of it. Huyang, the new imperial capital next to the East China Sea, is almost on the verge of becoming the largest import and export metropolis in Zhaoguo, which is the most obvious proof of this.

As the largest metropolis in the country's inland business travel, although it is no longer home to Kyoto, the emperor still takes great care of its establishment. The official roads in the neighborhood are still free for the people to cross, and for business travelers, a certain amount of money is charged according to the number of cars and horses.

In fact, when a merchant is doing business, sometimes he has something in common with the war march, that is, he pays attention to speed in order to earn the difference in price from place to place. These official roads have the quality to ensure the rapid driving of vehicles, coupled with the addition of guards at intervals in Shokoku because of its special status, so that this road also has a high level of safety protection, most of the business travelers who go to Kyoto from other places are willing to use the industry as a transit point, and the toll is nothing at all.

Therefore, when the speed of the carriage gradually slowed down, Mo Ye looked out of the window and saw that the caravan that had been quickly thrown behind just now slowly caught up. With Ma An's speed, it was already a lot faster than usual, and it was a bit terrifying that the huge caravan convoy was able to catch up with this speed and have the posture of slowly moving ahead.

The sound of horses' hooves and the sound of wheels rolling on the ground approached like thunder, and Lin Shan, who was leaning on the pile of books, had also hurriedly glanced at it when his carriage had overtaken, so now he knew in his heart that it was the caravan that had caught up. But instead of asking Ma An to speed up and overtake, he asked Ma An to move the carriage closer to the side of the road and slow down a little more.

In this way, the caravan can overtake faster.

But despite this, when the whole team of wagons completely overtook the front, it took two tea shots. And looking at the dust outside the curtain of the carriage raised by the wind, and the dust stirred up by the caravan carriage and horses, Mo Ye also instantly understood the reason why Lin Shan gave way. If you were on the same page as it just now, I don't know how much ash you would have to eat. Mo Ye couldn't help but sigh in his heart. Sometimes it's good for everyone to back down at the right time.

Mo Ye thought of this, and when Ma An saw the cloud of ash in front of him that had not yet dispersed, he was only one step too late. But he just thought of the appearance of the same thing as Mo Ye, but in this part of his understanding, it was completely different from Mo Ye.

Therefore, after slowing down the speed of the car for a few minutes, Ma An turned back to Lin Shan in the car and complained: "We should have overtaken the front just now." Why follow someone else's convoy like you do now? ”

Lin Shan shifted and approached the carriage door. Leaning on the side of the door and opening the curtain halfway up, he looked at the distant convoy in front of him, and said to Ma An with a smile: "There were many clouds last night, I think there may be rain today." The weather was fine at noon. It's really gloomy at this point, so let's let someone else's caravan go first! Judging by the speed of their sports car, the cargo on the car should not be too heavy. Then it's probably not a bargain. ”

"Having said that, if we hurry up, it won't affect their itinerary!" Ma An did not agree with Lin Shan's kind words. After thinking about it, he analyzed: "You also said that you are in a hurry, and such a concession is not a way." You let this caravan pass, and you didn't think that there might be another caravan later? Are you going to let it go then? ”

Lin Shan only shook his head slightly at Ma An's concern, and then said slowly: "Maybe you don't know, His Majesty the Emperor has been more meticulous in managing business travel in recent years. Merchants who reached a certain scale were subject to the merchant's emblem issued by the imperial court. It's a protective measure, but it's also a balancing. Large business travelers with unique emblems can get some preferential treatment when they travel through the counties and counties of Guò. But it can also be shackled. ”

Lin Shan paused when he said this, and after a deep groan, he said, "For example." If the number of carriages and horses reaches more than 30 times, the convoy with the emblem of the merchant must arrive at the city gate at the time of Shen, and the latest is not more than the unitary hour.

Hearing this, Ma An suddenly said: "So, I'm afraid this caravan is the last column on the official road today?" ”

Lin Shan nodded and said, "This kind of large caravan entering and leaving the city will be recorded. As the largest commercial capital in the interior, most of the merchants who often pass through here are not ordinary people, and they have formed a kind of consciousness from shrewdness, if they want to ship goods in large quantities, they will prepare the date in advance. Therefore, even if the caravan just now is not the last rank, it is estimated that it will not exceed two columns. ”

Lin Shan's explanation made Ma An speechless for a while. He was not aware of the changes made by these imperial courts, but he had reason to believe in the truth of what Lin Shan said, which alone was very convincing.

Mo Ye, who had been listening in silence, saw that Ma An stopped talking, but she said a trace of doubt in her heart.

"Master, why did the gates of the capital of Yedu ban trading houses so early? If in the summer, the sun is still dazzling in Shenshi, and Shenshi is a long time away from the time when the city gate is really closed! Mo Ye hesitated for a moment before adding: "Isn't this regulation too harsh?" ”

"Yedu used to be the imperial capital, the weight of the country, and its city tower system is more capable of holding on than ordinary city towers. Later, although Kyoto moved to Huyang, the garrison of the capital was still not relaxed, because the capital has become the largest commercial capital, and nearly forty percent of the people in the city are outsiders, even if there is no external turmoil, the security in the city is extremely heavy. ”

Lin Shan took a deep breath and said slowly: "So when a large caravan enters the Yedu, the inspection procedures are naturally more complicated and time-consuming, and this is just to prevent accidents. Now there are three gates in each of the four directions of the castle tower, and the 'Tianzheng Gate', which is usually not open to the common people and is actually preset in wartime, has now been pardoned by His Majesty the Emperor as a place for large business travelers, which is already a big concession. So you can't say, let the gates of this heavy city remain open after dark! ”

Casting road, you can understand that the square groove-shaped roadbed is dug out of the road surface first, the bottom is compacted, and then the stone is mixed with soil and other stains, and then poured into the road groove, waiting for it to solidify into a whole.

There was no concrete in ancient times, but many ancient city walls in our country still stand up after wind and rain, which can prove that the solidification of the ancient city tower is not worse than concrete, and the biggest difference may be that the traditional curing is much slower than the curing speed of modern concrete! and that "ancient concrete" cannot be used immediately, and requires temporary processing to produce a finished product.

It's all empty text, and I can make up a little bit more on unproven technology.
