Zhao Chongyu thought that he was going to run to the Seoul earthen fort resolutely, staged a business trip, suddenly arrived to find out the slackness of the garrison soldiers, and then burned three fires or something. This kind of routine is not uncommon, so there is not much sense of expectation. With a cold sideline attitude, he watched from the side how the new town guard envoy performed.

As soon as Li Siye went out, he stopped, turned his head and instructed Yan Xiaosi behind him: "Go and nail the stake." ”

Yan Xiaosi turned over and dismounted, and together with two personal soldiers, he took out the sharp wooden stake behind him, and nailed it into the soil along the northeast corner of the city wall.

Soon a carriage came out of the city gate, the carriage was covered with a black curtain, the coachman pulled the carriage to the position of the wooden stake, jumped out of the carriage and got into the carriage to tinker for a while, and then jumped back on the carriage, and said to Li Siye: "General, it is ready." ”

Li Siye nodded, raised his horsewhip and pointed ahead: "Let's go!" ”

Zhao Chongxuan was very depressed in his heart, but it was inconvenient to have a seizure, so many people waited for a long time, it was actually to wait for a coachman?

Every mile, drums would sound on the veiled car, and they would slow down a little to see if there was any special feature nearby. The drum cart traveled out of Bali, found the riverbed of the Ji River, followed by Li Siye's ugly pawn Feng Changqing, who was carrying the silk cloth on his back, untied the silk cloth from his back, turned over and dismounted and spread it on the ground, and pressed the four corners with stones. He took out the pencil case and inkstone from his arms, took out the tiniest and held them in his hand, looked up and asked Li Siye: "General, how should the riverbed of the Ji River be represented." ”

Li Siye groaned slightly, raised his head and said, "Draw a dotted line." ”

The mileage of the drum car is used for reference, not the actual number, the carriage in the process of walking in a straight line as much as possible, it will inevitably encounter terrain obstacles, and it needs to be folded, which needs to calculate the mileage of the folding, and the distance is a straight line after deduction.

At this time, the drum cart made a crisp cymbal sound, and Feng Changqing jumped off the horse again, spread the map on the ground, and began to draw in the square of inches.

At this time, why didn't Zhao Chongjun understand what the carriage was? It turned out to be a drum car! This thing only came in handy when the imperial court was building city walls and drawing a map of the whole country. Unexpectedly, Li Siye just drew the defense map of Shule Town, Anxi, and used such a precise thing, which is simply ...... Where did this drum cart come from? How could he have this thing, and he didn't see him have this car when he brought his family into the city a few days ago?

Basically, the border town draws a map, all of which are used in the simplest visual method, as simple as what mountains, what ridges, what rivers, or what roads will be drawn in the area, and the error is not called an error of two to three miles, and the arming map will not record what a natural village is called, only the approximate location of the post station, the guard, and the beacon, and there is no scale concept, most of the things that will appear on the map to look at the two places close to each other, but in fact, they have to run far away.

Maps of the Tang Dynasty were already very popular, and there were maps in all counties, states, and provinces, most of which were rough and simple. Really fine maps are only available in the imperial court, and they are only atlases of important areas, such as Guanzhong, Chang'an, and Luoyang. Pei Xiu's Yugong map of the Western Jin Dynasty has long been lost, and the finely measured map of the whole country is the "Hainai Huayi Map" drawn by Jia Tan in the first year of Dezong Zhen, which not only marks the ancient names and current names of the prefectures and counties in the country with two colors, but also draws more than 100 countries around China.

Li Siye wanted to draw a Shule defense map, and he was not surprised, but the use of the car to write the cloth defense map could be regarded as an eye-opener for him, so that he had a preliminary understanding of the rigor of this town envoy. This kind of surprise is probably about the same as the construction of a building in a prefecture-level city, and the Chinese Academy of Sciences was invited to come and measure it. This made him even more suspicious of Li Siye's identity, this is not just a general.

Could it be that he is also one of the Longyou Li clans, is he from the Gu Zang room or the servant room?

After arriving at the 10-mile mark, the cart nailed a wooden stake to the spot and began to turn southward, covering half of the 10-square-kilometer area, and they finally arrived at Seoul in the afternoon according to this method of entering and folding.

Seoul is a simple military fortress, belonging to the category of forts, which is smaller than the garrison and larger than the fortress. The length and width are about 300 paces, and a team of troops is stationed.

Feng Changqing stood under the city wall and drew the measured location of Hancheng on the map, although it occupies a small area, but according to the measured size, he still used a fine pen to draw small squares at the size of the map square, and marked the Han castle next to it with a red pen.

Li Siye and Zhao Chongyu entered the fort, this city wall made of rammed earth is quite thick, the bottom is more than five zhang wide, the top is also four zhang, the top female wall is also made of rammed earth, and the soldiers' houses are directly dug out of the castle wall. On the left side of the wall are stables, on the right side are barns, and on the north side are forts, making the central site seem very small, barely a school for fifty people.

The team stationed here is also called the captain of the fort, and he followed Li Siye behind them to enter the fort building, which has two floors, and the ground floor is where the team is staying and working, and it is necessary to climb the wooden ladder to go up to the top.

There was a beacon tower on the top of the fort, and there were four movable ballistae, from the top of the fort tower through the steps to the city wall. The fortifications of the four walls are comprehensive, and the spiked spur wood is drawn by reels and hemp ropes, which can be used repeatedly.

The soldiers changed their guards in four shifts, from the fort tower to the four corners of the city wall. Li Siye is very satisfied, this should be a model template for the Tang army to garrison the border in Shule Town.

But when he came down from the city wall, he saw a fire digging a hole in the wall, and he set up a bucket on the stove to burn firewood, and stirred it in the pot with a copper spoon, and bubbles were rattling on the surface of the water.

Li Siye looked over and saw that it was a mushy thing, and it should be porridge cooked with barley grains, millet grains, and a small amount of brown rice, not to mention the smell, it was difficult to swallow just by looking at it.

The gang leader waved the bronze spoon and tapped it on the edge of the bucket, "It's time to eat!" It's time to eat! ”

The soldiers who were resting in the cave ran out in twos and threes and began to line up by the stove. There was a general watching from the side, and the fire chief in charge of the spoon looked very nervous, and even the cooking was a standard two spoons, and everyone was divided fairly and evenly.

Among the soldiers, only two of them lined up with coarse porcelain bowls, and the others held the dough in their arms, and after two spoonfuls of it, they squatted in the corner with the doutou and poured the porridge into their stomachs.

Li Siye was a little sad and disgusting at this scene, the helmet and the rice bowl were mixed, aren't you afraid of eating the head oil in your stomach? No, there will be no head oil, where does the head oil come from without a little bit of oil, but there must be lice, not to mention microorganisms and bacteria, which is too unhygienic.

Li Siye only frowned slightly, but he didn't say anything, he and Zhao Chongxuan walked to the stable again, there were two cows used to drive, more than a dozen thin horses with leprosy, they looked sick, the horses' hooves were very worn, and there were no shoes on them.

He pointed to the horses and turned back to the team and asked, "Is this a stallion or a private horse?" ”

The team was bowing down and said in a low voice: "It's a private horse, we garrisons, there is no stallion available." ”

"Why don't you take good care of your own horses?"

"General Qiyu, it's not that I haven't taken good care of it, but I can't do it, these horses are infected, and it costs a lot of money to bring them to Shule for veterinary treatment, and no one wants to sell them, these years the horses in the Western Regions have become cheaper and cheaper, and the military horses are cheaper, we don't have extra money to treat them, so we can only leave them like this. Fortunately, these two cows usually pull the cart when picking up the grain and grass. Oh, these two cows belong to the public, and we take care of them better than people, and if the cows die, my team will be dismissed on the spot. ”

The team was following behind Li Siye to tell about the difficulties, and Li Siye listened to them one by one and remembered them in his heart.

They walked out of the Han Castle, and the team was leading a few soldiers to bow down and cross their hands: "Congratulations to the general!" ”
