Yuan Fang said with a smile: "It's good to get used to it, now it looks dark, and after a while, the color will be lighter after the surface is covered with dust, well, it's probably dark gray." ”

Jiang Chengjia tilted his head and thought for a while: "Dark gray, well, it's okay." ”

Guan Xiaoyun ran back and forth a few times like a ghost finding a new toy, and finally panted and said, "Dean, this thing is so good, you don't have to worry about stepping on the pit and getting your feet in it." Guan Xiaoyun's eyes are not very good, and he often walks on his feet.

Da Mei asked: "Now it seems that there is no problem for people to walk on it, but I don't know what the effect of the carriage will be?" Especially some heavy-duty carriages, those wooden wheels are hard and narrow, and will not press out the ruts. ”

Sang Rou nodded and said, "Well, the rut thing is so annoying, sometimes it's easy to fall off if you accidentally step on it when riding a horse." ”

Guan Xiaoyun was eager to try and said, "Dean, why don't we try?" ”

Yuan Fang squatted down and touched the ground that was still a little warm, shook his head and said, "The asphalt has not completely solidified, if you want to try, it will be tomorrow." ”

Guan Xiaoyun sighed a little disappointed, and then went to the blacksmith furnace to have a chat with a few blacksmiths who were also novel and researched the ground, seeing Yuan Fang crying and laughing, he felt that this product was becoming more and more abnormal now, no matter who he was with, even if it was the first time they met, they could chat like old friends for a long time.

Yuzuki, who had been silent, frowned and said, "Brother-in-law, this asphalt road is really good, but I don't feel like it's suitable for horseback riding. ”

Everyone looked at the amazing Yueyue, and Sang Rou was puzzled and asked, "Why?" ”

Yuzuki found an iron band the length of two knuckles from the blacksmith's furnace and threw it on the ground, raised his foot and stepped on it, rubbed it vigorously, and said, "It's too slippery." Everyone fell into deep thought, and it took a while to understand the meaning of the moon.

Sang Rou stepped on the iron tendon and tried it and said: "It's a little slippery, but it's much stronger than the bluestone pavement, Yuyue, your worries are a little redundant." ”

Da Mei agreed: "Yes, this should be better than Qingshi Road." ”

Yuyue waved his hand and said: "I'm not saying that asphalt roads are bad, my brother-in-law said that all the pipeline roads in the empire should be paved with this kind of asphalt road, I think asphalt roads are only suitable for use in the city, and the pipes outside the city are not very suitable." ”

Xin Huilan was puzzled and asked, "Why?" ”

Yuzuki explained, "If you think about it, whether it is an army commander or a local messenger, they all deliver news as quickly as possible, and if you gallop on such a road, it is easy to have an accident. Oops, how to say it. Yuyue was so anxious that her face was red, and she didn't know how to phrase it to express her meaning clearly.

Yuan Fang, who has been silent, opened his mouth to relieve the siege and said: "Horseshoes are the easiest to wear, so it is generally necessary to add horseshoes to the horseshoe, and the horseshoe is very smooth, when walking on the ordinary road, relying on the horse's own weight can be pressed into the ground to increase friction and maintain stability, but it is obvious that the horse gallops on the asphalt road to lose this role, the friction is sharply reduced, and it is difficult for the horse to turn or slow down as before, and it is easy to slip and fall when encountering an emergency. ”

Yuzuki nodded vigorously and said, "Yes, that's what I meant." ”

Yuan Fang nodded slightly, touched his chin and said, "Well, this is indeed a problem. Yuan Fang's exposition explained the truth, and everyone suddenly understood.

Sang Rou was a little unwilling and said, "Such a good thing, do you want to give it up?" ”

Xin Huilan said: "It cannot be completely denied, although such a road surface is not suitable for solo riding, it is very suitable for horse-drawn carriage freight, if all roads are asphalt, the speed of cargo transportation can be at least doubled." ”

Jiang Chengjia added: "Traveling by horse-drawn carriage will not be as bumpy as before, and at that time, our human-powered tricycles can also expand the scope of operation, extending to the surrounding towns and villages, as well as bicycles, and there is no need to worry about the road is not easy to walk, in that case, people outside the city can also buy bicycles to travel, how convenient." ”

Yuan Fang pressed his hand and said: "What you said makes sense, I'll think about this matter again, and you can also help think about it, let's unite and definitely think of a solution." ”

Guan Xiaoyun saw that there was a gloomy cloud here, and came over to ask Sang Rou what happened, after listening to Sang Rou briefly explain what happened, Guan Xiaoyun smiled and said, "What's so difficult about this?" Wouldn't it be enough to separate? ”

Yuzuki was surprised and asked, "Separate?" How to separate? You're not trying to say another road, are you? ”

Guan Xiaoyun found a piece of charcoal, squatted on the ground and said while drawing: "The pipe is so wide, enough for eight carriages in parallel, we can vacate the places on both sides, and only pave the asphalt road in the middle, so that the carriage and the horses will go their own way and will not interfere with each other." ”

Yuan Fang's eyes lit up, and he said approvingly: "Well, this method is good, but the pipeline is also very narrow in some places, what should I do in that kind of place?" ”

Guan Xiaoyun drew a curve on the ground and said: "I have been to many places, most of what you said are some curves, just like Yuyue said, you can rebuild a dirt road for horses to pass, anyway, there are not many such places." ”

Sang Rou said: "Actually, there is no need to be so troublesome, even when riding a horse through these places, it will generally slow down, as long as it is not too fast, the asphalt road is not impossible to ride." ”

Yuyue thought for a while, nodded and said, "Well, Sang Rou is right, if that's the case, what about the rural road, the rural road is not as wide as the pipeline, and there won't be much left if you leave the horse road." ”

Yuan Fang said with a smile: "This is easy to do, when laying the rural road, it can be widened, the project is a little bigger, but it can be done once and for all." ”

Xin Huilan said: "Actually, there is no need to be so troublesome, the roads in the countryside are crisscrossed, and there is not only one road, just leave a few special horse roads when paving the road." ”

Yuan Fang slapped his thigh: "It's done, it's still a lot of people with great strength, and this matter is solved." Everyone had a happy smile on their faces, they didn't expect such a big matter to be solved so easily, and everyone had a sense of accomplishment, especially Guan Xiaoyun, who made important suggestions, was a little fluttery after being praised by Sang Rou and Yuyue for a few words.

Seeing the asphalt pavement, Xin Huilan and Jiang Chengjia took the first step and went back to rest, while Damei had been accompanying Yuan Fang and had to go back together after the completion of the project.

Also, there is no entertainment in this world, and there is nothing to do when you go home, either you are in a boring daze or chatting about repetitive topics, and it is also a good choice to stay here and watch the excitement.

Experience continues to accumulate, the workers perform their duties, the speed gradually increases, Yuan Fang and they are talking, the pavement of the alley outside the backyard of the Chamber of Commerce has been paved, and the street has begun to be paved.
