North and South groceries

Although Chang'an City in February could already smell the breath of spring, the air was still chilly.

Two days ago, there was another snow scum. The fine snowflakes fell on the ground and were trampled by passing pedestrians, cattle and horses, and soon turned into mud. Get muddy.

Those who ride horses and ride cars are fine, but it is very inconvenient for ordinary people to go out. After going out for a walk, they often have muddy feet, their shoes are soaked in muddy water, and their feet are soaked in the cold muddy water. In the middle, the taste is very uncomfortable.

At this time, many craftsmen and servants were dispatched from Chang'an County to start building roads on several roads leading to the East and West Rooms, and this time the main material they used was cement.

When Luo Yong gave the recipe for burning cement to Tang Jian earlier, it was winter, and the roads in Chang'an City were also covered with snow and ice, which was not suitable for starting work, so His Majesty the Emperor ordered people to study this recipe carefully to see Is there anything that needs to be improved? According to Tang Jian, there seems to be other firing methods for this cement.

When Luo Yong gave this recipe to Tang Jian, he mentioned it a little bit, saying that it is not necessarily to use these few ingredients to cook, and there may be other recipes. He did not forget to mention this to His Majesty the Emperor, and the Emperor did not miss this message. He ordered people to start researching this method of burning cement that day, and his attitude was quite tough. In his opinion, since Luo Sanlang said so, then this method It can definitely be adjusted again. If those officials and craftsmen can't research it, it is their dereliction of duty. What will happen to their dereliction of duty?Lose my job.

So those people, under the pressure of losing their jobs, studied day and night for two months on the basis of Luo Yong's prescription.

After these two months of research, they not only thoroughly understood Luo Yong’s original recipe, but also gained a lot. They found that if the proportion of yellow mud is appropriately reduced and the amount of lime is increased, the fired cement will be stronger. If clay used for pottery is used instead of yellow mud, the color of the fired cement will be blue-gray, and the quality of this blue-gray cement is better than the original khaki-yellow cement.

In addition, they have made many different attempts. After all, high-quality pottery clay is not available everywhere, but loess is everywhere in Xipo Village. That prescription is slightly insufficient.

But in any case, the idea of ​​using clay instead of yellow mud and the fact that it is feasible has given these people great confidence. After that, they kept trying other materials, because they are used for paving roads, and the amount of materials used is huge. Naturally, the more common and cheaper the better, and the formula they finally presented to the emperor was already a very mature cement formula.

When offering the prescription, these people were very excited, but the emperor seemed to have expected it a long time ago, and did not appear too surprised.

After all, with Luo Sanlang's original recipe as the basis, and he reminded him to try other materials, if he still can't research it, then the group of people under his hands must be living for nothing.But in any case, the reward has to be rewarded.

In addition, before repairing the road on the side of the palace, the emperor ordered people to go to the east and west cities to repair the road, and the matter was handed over to the magistrate of Chang'an County.

So, a few days later, there was this scene of road construction in Chang'an City.

Although this is an age of information occlusion, relatively speaking, people in Chang'an are much more informed than other places.

Many people in Chang'an have heard that there is an unusually smooth concrete road between Lishi County and Xipo Village. The road surface is like a polished stone surface, and cars drive on it It was like walking on the clouds. While everyone was amazed, many people had a bit of disbelief in their hearts. They only thought that the world passed on Na Luo Sanlang more and more miraculously.

This time when the cement road was being built in Chang'an City, many people went to watch the excitement. They saw that the powdery things were poured on the ground, mixed with clear water and fine sand, mixed into mud, spread on the ground, and finely ground with tools. leveled...

The newly paved concrete road is still very soft, and a poke on it with your hand will make a hole. On the second and third day, the road surface is getting harder and harder, and soon pedestrians can walk on it, and then horses and horses will walk on it. And more and more.

In February of the tenth year of Zhenguan, people living in Chang'an City developed a rather unique entertainment, that is, to go shopping around the two cities if they have nothing to do. Yan'er is flying, and the one trip is not enough, so turn back and go again, the horseshoe and cow's hoof trampled on the road, making the residents on both sides of the road very distressed.

At that time, there were not many places in Chang'an City that had built this kind of cement road. Everyone was very happy and proud of having a cement road in front of their house, but they were gradually trampled on later. If there are too many, they feel that they are at a disadvantage. Those places where roads are built late must not be trampled so hard.

During this period of time, the topics of Chang'an people basically revolved around the concrete road.

It was at this time that Chen Mian, a doctor of Taixue, found Qiao Junlin. After some conversations, it was decided that Qiao Junlin would be a student of Taixue. Within a few days, he became a student of Taixue.

In mid-February, Chen Weng took several disciples on a study tour, including Qiao Junlin.After all, this Taixue is no better than those schools that study calligraphy, mathematics, and mathematics. There are very few students in Taixue, and each master has fewer disciples. Most of the people who can come here to study are from good families, and the school has always adhered to the principle of elites. Regarding the education policy, the school had no objection to this study tour, nor did the parents. The students were all very happy, so they set off happily.

Because Qiao Junlin didn't have a carriage, Chen Weng let him ride in the same carriage with him. Naturally, he did not miss his homework on the way.

I heard that this young man has not been in school for a long time, but his foundation is quite stable. Presumably he must have put in a lot of hard work. Considering his young age, it is really rare, so he has taught him a lot along the way.

Regarding Qiao Junlin's background, Chen Weng didn't have any opinion. After all, his own background was not very good, and because he had to deal with these gentry children all the year round, he often got angry a lot. , he actually likes it in his heart.

At the end of February, under the leadership of their husbands, several Taixue students came all the way to Lishi County. When several carriages entered the city, they were also stopped by the guards and asked a few words. Only after that was he willing to let go.

If it were in the past, people like them would not be stopped for interrogation. After all, one only needs to look at the carriages to know that this group of people is either rich or expensive, and their place is not a military important place. It's pretty good to have guards guarding the city gates, how could they all ask so carefully.

It’s just that from a while ago, for some reason, Governor Hao became very concerned about their job of guarding the gate, which made them dare not slack off. Anyone who wants to enter the city, except for some familiar faces, is an individual and they all know it. Gotta ask.

When a group of people came to Decheng, they first went to eat at the restaurant owned by the Wang family. At that time, Dr. Chen asked Qiao Junlin if he wanted to go home and have a look.

"It's okay, it's getting late, let's go to Xipo Village after dinner." Qiao Junlin replied at that time.

In the end, Qiao Junlin's father heard the news from somewhere, and brought his youngest son to find him.

Qiao Junlin's father was also educated, and he usually felt that he was not on the same level as those who could not read a few big characters. At this time, when he saw these doctoral students from Chang'an City, he felt that he was meeting someone of the same kind. They are very enthusiastic.

"Since Da Lang is back, he should go home and have a look." After exchanging pleasantries with Dr. Chen and others, Father Qiao asked Qiao Junlin.

There was no shortage of words and there was a bit of reprimand, which probably meant that he didn't know that he had to go home to have a look after he came back. If he could lure these people to his home, it would definitely be more interesting than him running over by himself now. face.

"It's getting late today. I originally planned to lead my husband to Xipo Village first, and then come to visit Yeniang tomorrow." Qiao Junlin replied.

"Since that's the case, I'll ask your aunt to cook more of your favorite meals tomorrow." At this time, Father Lin also served him with the appearance of a loving father, a loving father and a filial son. This is the common pursuit of many people, even if it is not the case inside, You should always put on a show on the surface.

"Please trouble Ye Niang." Qiao Junlin only replied lightly.

Father Lin didn't care, he said a few more words earnestly, and then left with his youngest son.

After dinner, they set off again. In a carriage behind them, two young men started talking about Qiao Junlin and his father.

"Then why is Qiao Junlin so indifferent to his own father?"

"Who knows."

"Could it be that just now you have a bit of a human appearance, so you can't even look down on your newborn father?"

"His father's behavior is really embarrassing."

"On the contrary, they are not very acquainted with people, and they are too warm."

"Anyway, that's his father, too."

"I think his younger brother is well-behaved. It doesn't seem like he keeps a straight face all day long, but rather like someone who owes him money and doesn't pay him back."

"Boring and utilitarian, it's really not pleasant."

The car Qiao Junlin was riding in was at the front of the line, so he naturally didn't know what the people behind were talking about him. Even if he knew, he probably wouldn't show any expression to these two people.
