In early summer, the weather is gradually getting hotter, Li Zhang originally thought that sitting in the carriage was too stuffy, and it was cooler to ride a horse, but he immediately gave up after riding for a while, and then got into the carriage and didn't come out, because there were too many insects in early summer, and he couldn't open his eyes when riding on a horse, and the road was full of floating soil, and there was a yellow veil everywhere when people and horses walked by, which could make people feel extremely uncomfortable after a while.

"When will it be done?" Li Zhang looked at the rolling dust outside the window and couldn't help but say helplessly, and immediately closed the window after speaking, rushing in the summer is simply looking for guilt, not only is the carriage extremely hot, but also the window can not be opened, otherwise the dust outside will come in, and after a while, people's faces can be covered with a layer of loess mask.

The reason why there is so much dust on the road, in addition to the recent dry weather, there has been no rain for many days, the most fundamental reason is the road, because the roads of the Great Song Dynasty are almost all dirt roads, and this kind of dirt roads are all floating soil when the weather is dry, although the rain will be better, but after the rain will make the road muddy, sometimes even impassable, seriously affecting the traffic, and the only way to solve the above problems is only road hardening.

There are many ways to harden the road, such as paving the brick road, stone road, etc., in addition, you can also use cement and asphalt to pave the road, which can harden the surface of the road, so that whether it is drought or rain or snow, you can pass normally, and the traffic is to maintain the relationship of national rule, which has an important impact on politics, economy, and military.

However, although the road hardening is very good, but now the Great Song Dynasty can't do it, because the cost is too high, not to mention the bricks and stone slabs, these materials are at most paved in some people's homes, or small alleys and the like, if the official roads of the Great Song Dynasty are paved with these, I am afraid that the Great Song Dynasty will immediately go bankrupt.

In addition, cement can be considered, Li Zhang knows the method of firing, but this thing needs to consume limestone, gypsum and other materials, in addition to coal as fuel, the cost is still not low, as for asphalt, don't think about it, unless the Great Song Dynasty has a way to exploit oil on a large scale, of course, there is some oil in the northwest that can flow out by itself, and the fire oil bombs in the army are made of this thing, but the quantity is too small.

"Speaking of which, productivity is still too backward!" Li Zhang finally sighed, it is too difficult to improve the productivity of an era, even if he exhausts his life, he doesn't know how far he can go?

"Big brother, you can see Tokyo City ten miles ahead!" At this moment, I only heard the wild dogs outside knock on the car window and report to Li Zhangyu.

When Li Zhang heard this, he opened the window, and immediately saw a wild dog covering his face with a face towel, even a wild dog couldn't stand the dust on the road, and he had to cover his mouth and nose with a face towel when riding a horse, otherwise he would only eat soil along the way.

"Let's hurry up, return to the capital tonight, and I invite everyone to Huiwei Zhai for a big meal!" Li Zhang turned his head to look ahead, and then opened his mouth and ordered, this time he returned to the capital is not only him and the wild dogs, but also the guards sent by Cao Wei, these soldiers have also worked very hard along the way, so Li Zhang wanted to reward everyone after the capital.

The wild dog immediately passed Li Zhang's words out loud, and as a result, the soldiers who were a little listless by the cool sun and dust heard it, and they were all immediately shocked, although they didn't know what place Huiwei Zhai was, but they all knew that Li Zhang was generous, and he was also very considerate to them, and the place where he could treat him was definitely not ordinary.

Under Li Zhang's encouragement, the speed of the team also accelerated a lot, after all, they didn't want to bask in the sun on the road, and the earlier they arrived in the capital, they could rest earlier, and at the same time, Li Zhang invited guests to dinner, so everyone was full of energy to rush forward.

The distance of ten miles passed in a flash, and when I went forward, the towering city wall of Tokyo City also appeared in front of everyone, many of these soldiers from the northwest came to the capital for the first time, and when they saw the tall city wall of Tokyo, they immediately made an exclamation sound, saying that although Gyeongju is also a strong city, it is simply too bad compared with Tokyo City.

Li Zhang also didn't care about the dust here, stretched out his head from the window and looked out, when he saw the familiar city wall of Tokyo, he couldn't help but feel a little emotional, remembering that he left the capital last autumn, he thought he would be able to come back before the year, but he didn't expect that this would be more than half a year, during which Zhao Zhen, Tanuki, Douzi and others also occasionally sent letters, but after all, the distance is far away, and the content of the letters is limited, so Li Zhang is not very clear about the situation in the capital.

The capital is in front of you, Li Zhang's team sped up again, but the so-called Wangshan ran a dead horse, and Tokyo City looked right in front of them, but they didn't come to the gate of the capital until the sun afternoon, and then the group entered the city, and the soldiers who came to the capital for the first time were also curious along the way, and seemed to feel very fresh about everything in the capital.

Li Zhang was not in a hurry to go home, but took this group of people to the official post to settle them down, and after everyone freshened up, he took them to Huiwei Zhai to fulfill the previous promise, this time he brought not many guards, and the total was only fifty people, after all, walking in the territory of the Great Song Dynasty, fifty people were enough to protect Li Zhang's safety.

"Big brother!" As soon as Li Zhang entered the door of Huiwei Zhai, he screamed excitedly when he saw Huozi, and then pounced on him and hugged him tightly, and at this time, the ugly lady in the store also came out of the back kitchen when he heard the sound, and when he saw Li Zhang, he also shouted with joy, and the other brothers in the store also stepped forward at this time, surrounding Li Zhang and asking non-stop.

Li Zhang also smiled and chatted with Huozi and them, and then asked Huozi to arrange for these guards he brought to eat, and he asked about the situation at home during this time, and the result reassured him that nothing happened at home, Tanuki They read at home every day, Ugly Niang and Huozi take care of the family's business, Lu Wu and Li Yong and they also have their own things to do, everything seems very calm.

It's not early now, Li Zhang estimates that it's a little late to enter the palace now, and there must be a curfew when he comes out, so after chatting with the ugly girl for a while, he decided to go home first to see the raccoon dog, according to the ugly girl just now, the raccoon dog wants to kill him during this time, and he has to mention him every day I don't know how many times, and Li Zhang misses this only sister very much, so after he said goodbye to the ugly girl, he immediately took the wild dog home.

However, when Li Zhang hurriedly returned to his house, he suddenly saw an inner attendant guarding his door, and when he saw him, he immediately stepped forward and said: "Li Ban has worked hard, the Queen Mother has a will, announce that you will enter the palace immediately!" ”
