In early summer, the weather gradually became hotter. Li Zhang originally thought that sitting in the carriage was too stuffy and riding a horse was cooler, but after riding for a while, he immediately gave up and got into the carriage and stopped coming out. Because there were too many bugs in early summer, he couldn't open his eyes when riding on the horse. In addition, the road was filled with floating soil, and the people were swinging everywhere when they walked by, which made people feel extremely uncomfortable in a short while.

"The road is hardened, when will it be done?" Li Zhang couldn't help but say helplessly as he looked at the dust rolling outside the window. After saying that, he immediately closed the car window. Xia Tian was simply looking for trouble when he was rushing. Not only was the carriage extremely stuffy, but the window could not be opened. Otherwise, the dust outside would sway in, and a layer of loess mask would be covered on his face soon.

The reason why there is so much dust on the road is that in addition to the recent drought and the rain has not been raining for many days, the most fundamental reason is the roads, because the roads in the Song Dynasty are almost all dirt roads, and these dirt roads are all floating soil when they are drought. Although it will be better when it rains, it will make the roads muddy after the rain, and sometimes even cannot pass, seriously affecting traffic. The only way to solve the above problems is road hardening.

There are many ways to harden the road, such as paving brick roads, stone roads, etc. In addition, cement and asphalt can be used to harden the surface of the road, so that it can pass normally whether it is drought or rain or snow. Transportation maintains the relationship between national rule and has an important impact on politics, economy, military, etc.

However, although the hardening of the road is very good, the Song Dynasty cannot do it now. Because the cost is too high, I won’t talk about bricks and stone slabs. At most, these materials are paved in the homes of some people, or in small alleys. If all the official roads of the Song Dynasty are paved, the Song Dynasty will probably go bankrupt immediately.

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

"After all, productivity is still too backward!" Li Zhang sighed at last. It is too difficult to improve productivity in an era. Even if he spends his whole life, he doesn't know how much he can do?

"Brother, you can see Tokyo City ten miles ahead!" At this moment, the wild dog outside knocked on the car window and reported to Li Zhang.

When Li Zhang heard this, he opened the window and immediately saw a wild dog covering his face with a facial scarf. Even the wild dog could not stand the dust on the road. He had to use a facial scarf to cover his mouth and nose when riding a horse, otherwise he would have to eat dirt along the way.

"Let everyone speed up the journey. I will go back to the capital tonight. I will invite everyone to Huiweizhai for a big meal!" Li Zhang turned his head and looked ahead, and then ordered that this time he returned to the capital, he was not the only one who was the one who was sent by wild dogs, but also the guards sent by Cao Wei. These soldiers also worked very hard along the way, so Li Zhang thought of rewarding everyone after he arrived in the capital.

The wild dog immediately spread Li Zhang's words loudly, but the soldiers who were originally a little listless by Kuri and Dust were immediately shocked when they heard this. Although they didn't know where Huiweizhai was, they all knew that Li Zhang was generous and was very polite to them. The place where he could treat him was definitely not ordinary.

With Li Zhang's motivation, the team's speed also accelerated a lot. After all, they didn't want to bask in the sun on the road. They could rest earlier when they arrived in the capital earlier. At the same time, Li Zhang was also treating guests to dinner, so everyone was determined to move forward.

A distance of ten miles passed by, and when we moved forward, the towering walls of Tokyo City appeared in front of everyone. Many of these soldiers from the northwest came to the capital for the first time. When they saw the tall walls of Tokyo, they immediately made a marvelous voice. Speaking of which, although Gyeongju is also a strong city, it is much worse than Tokyo City.

Li Zhang didn't care about the dust here, and stretched out his head from the window to look out. When he saw the familiar city wall of Tokyo, he couldn't help but sigh. He remembered that he left the capital last autumn and thought he would be able to come back before the New Year, but he didn't expect that it would take more than half a year to go there. During this period, although Zhao Zhen, Li'er, Douzi and others occasionally sent letters, the journey was long and the contents of the letters were limited, so Li Zhang was not very clear about the situation in the capital.

The capital was right in front of me, and Li Zhang's team accelerated the speed again. However, as the saying goes, the horses ran to the mountain and died. The Tokyo City was right in front of me, but they walked until the afternoon of the sun to the city gate. Then the group entered the city. The soldiers who came to the capital for the first time were also curiously looking around, as if they felt very fresh about everything in the capital.

Li Zhang did not rush home, but took these people to the official post to settle them. After everyone washed them, he brought them to Huiweizhai to fulfill his previous promise. This time he brought not many guards, and there were only fifty people in total. After all, walking in the territory of the Song Dynasty, fifty people were enough to protect Li Zhang's safety.

"Brother!" As soon as Li Zhang entered the gate of Huiweizhai, Huozi screamed excitedly, then rushed up and hugged him tightly. At this time, the ugly lady in the store also heard the sound and walked out of the kitchen. When she saw Li Zhang, she screamed with joy, and the other brothers in the store also stepped forward one after another and surrounded Li Zhang and asked nonstop.

Li Zhang also smiled and chatted with Huozi and the others for a few words, and then asked Huozi to arrange the guards he brought to have for dinner. He asked about Chou Niang's situation at home during this period. What made him feel relieved was that nothing happened at home. Li Er and the others studied at home every day. Chou Niang and Huozi were managing the family business. Lu Wu, Li Yong and they also had their own things to do, and everything seemed very calm.

It's getting late now. Li Zhang probably entered the palace a little late now, and he must have had a curfew when he came out. So after chatting with Chou Niang for a while, he decided to go home to see Li Er and the others first. According to Chou Niang just now, Li Er almost wanted to die during this period and mentioned him countless times every day. Li Zhang missed this only sister very much, so after saying goodbye to Chou Niang, he immediately took the wild dog home.
