Although the breath of spring can already be smelled in Chang'an City in February, there is still a chill in the air. a There was another snowstorm two days ago.
The fine snowflakes fell on the ground.
They were trampled by pedestrians and horses, and soon turned into mud.
The road that had been dry for just a few days became mud again.
Get muddy.
Those riding horses and riding cars are not bad, but it is very inconvenient for ordinary people to travel.
After going out for a walk, they often have muddy feet, their shoes are soaked by the muddy water, and their feet are soaked in the cold muddy water. , the feeling is very unpleasant.
At this time, Chang'an County sent many craftsmen and servants 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 this recipe for burning cement to Tang Jian, it was winter, and the roads in Chang'an City were covered with snow and ice, making it unsuitable for construction.
Therefore, His Majesty the Emperor ordered someone to study this recipe carefully and see.
Is there anything that needs improvement?
According to Tang Jian, there seems to be other ways to burn this cement.
When Luo Yong gave this recipe to Tang Jian, he mentioned it a little bit, saying that it was not necessary to use these ingredients to cook it, and there might be other recipes.
After Tang Jian returned, he I did not forget to mention this to His Majesty the Emperor, and the Emperor did not miss this piece of information.
Ribian ordered people to start studying this cement-burning method, and his attitude was quite tough.
In his opinion, since Luo Sanlang said so, then this recipe can definitely be adjusted.
If those officials and craftsmen cannot study it, then It's their dereliction of duty.
How will they lose their jobs if they fail to do their duty?
So those people, under the pressure of losing their jobs, studied day and night for two months based on Luo Yong's prescription.
After two months of research, they not only 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 burned 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.
The quality of this blue-gray cement is better than the original earth-yellow cement.
In addition, they also made many different attempts.
After all, high-quality clay is not available everywhere, and in Xipo Village, loess is everywhere.
From this perspective, their recipe is better than Luo Yong’s original one.
That recipe is slightly lacking.
But in any case, the thought of using clay instead of yellow clay and proving its feasibility gave these people great confidence.
After that, they continued to try other materials, because they were used for paving roads and the amount of materials used was huge.
Naturally, the more common and cheaper the better, and the recipe they finally presented to the emperor was already a fairly mature cement formula.
When the party was presented, these people were very excited, but the emperor seemed to have expected it and did not show too much surprise.
After all, with Luo Sanlang's original recipe as the basis, and being reminded by him that he could try other materials, if he still couldn't figure it out, then the group of people under him would probably be freeloaders.
But no matter what, you should be rewarded.
In addition, before repairing the roads around the palace, the emperor ordered people to build roads in the east and west cities first, and the magistrate of Chang'an was responsible for this matter.
So, a few days later, there was this scene of road construction in Chang'an City.
Although this is an era of limited information, relatively speaking, people in Chang'an are still much better informed than other places.
Many people in Chang'an have heard before that there is an extremely smooth cement road leading to Xipo Village in Lishi County.
The road surface is like a smooth polished stone surface, and cars can drive on it.
It was like walking on the clouds.
While everyone was surprised, many people had a bit of disbelief in their hearts.
They just thought that the world spread the word about Narosaburo becoming more and more miraculous.
This time when a cement road was being built in Chang'an City, many people came to watch the excitement.
They watched the powdery stuff being poured on the ground, mixed with clear water and fine sand, mixed into mud, spread on the ground, and finely ground with tools.
The ground has been leveled The newly paved cement road was still very soft.
If you poked it with your hand, you would see a hole.

On the second and third days, the road surface became harder and harder, and soon pedestrians could walk on it, and then cars and horses could walk on it.
More and more.
In February of the tenth year of Zhenguan, people living in Chang'an City developed a rather unique entertainment, which was to go shopping around the east and west cities.
Some rode horse-drawn carriages, some rode ox-carts, and some rode horses.
The swallows are flying, and if one trip is not enough, then turn back and walk again.
The horses and cows' hooves trample on the road, which makes the residents on both sides of the road feel very distressed.
At this time, there were not many places in Chang'an City that had built this kind of cement road.
Everyone was still very happy and proud to have a cement road in front of their home, but later it was gradually stepped on by others.
If there are too many, they feel a bit disadvantaged.
Those places where roads were built late must not be trampled so hard.
During this period, the topics of Chang'an people basically revolved around cement roads.
It was at this time that Chen Mian, a doctor of Taixue, found Qiao Junlin.
After some dialogue, it was decided that Qiao Junlin would supplement 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 the Four Schools of Learning and Calculation.
There are very few students in Taixue, and each teacher is responsible for fewer disciples.
Most of those who can come here to study are from very good families, and the school has always upheld the elite Regarding the education policy, the school had no objection to this study tour, and neither did the parents.
The students were very happy, so they set off happily.
Since Qiao Junlin didn't have a carriage, Chen Weng asked him to ride in the same carriage with him.
Naturally, he also tested his homework along the way.
I heard that this young man has not been in school for a long time, but his foundation is quite solid.
He must have worked hard.
Considering his young age, it is really rare, so he has been taught a lot along the way.
Regarding Qiao Junlin's background, Chen Weng didn't have much 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.
For this exceptionally hard-working young man from a poor family, , he actually liked it in his heart.
At the end of February, several Taixue students, led by their husbands, came all the way to Lishi County.
When several carriages entered the city, they were also stopped by the guards guarding the city and asked a few questions.
They saw their road signs.
Only then will they be released.
In the past, a group of people like them would not have been stopped and questioned.
After all, just by looking at those carriages, you can know that this group of people is either rich or noble, and their place is not a military center.
It's already good to have officers guarding the city gates, but how can we ask everyone so carefully.
But starting some time ago, Governor Hao somehow became particularly concerned about their job of guarding the gates, which made them dare not slack off.
Anyone who wanted to enter the city, except for some familiar faces, was everyone.
Gotta ask.
When a group of people entered the city, they first went to a restaurant owned by the Wang family to have dinner.
At that time, Dr.
Chen asked Qiao Junlin if he wanted to go home and have a look.
"It doesn't matter, it's getting late.
Let's go to Xipo Village first after dinner."
Qiao Junlin replied at that time.
As a result, Qiao Junlin's father heard the news from somewhere and came over with his young son.
Qiao Junlin's father was also educated, and he usually felt that he was not on the same level as those who didn't know a few Chinese characters.

When he saw these doctoral students from Chang'an City, he felt that he was meeting people of the same mind.
They are very enthusiastic.
"Since Dalang is back, it's time to go home and have a look."
After greeting Dr.
Chen and others, Qiao's father asked Qiao Junlin.
There was a hint of reprimand in his words.
It probably meant that even though he was back, he didn't know that he had to go back home first.
If he could lure these people to his home, he would definitely look more powerful than him running here by himself. face.
"It's getting late today.
I originally planned to take my husband to Xipo Village first and then come over to visit Ye Niang tomorrow."
Qiao Junlin replied.
"In that case, I will ask your mother-in-law to cook more of your favorite meals tomorrow."
Father Lin acted like a loving father at this time.
A father is kind and his son is filial.
This is a common pursuit of many people, even if it is not the case inside.
You should always put on a show on your face.
"Sorry for bothering you, mother."
Qiao Junlin only replied lightly.
Father Lin didn't care.
He spoke a few more words with seriousness and sincerity, and then left with his little son.
After dinner, they set out again.
In a carriage behind them, two young men started talking about Qiao Junlin and his father.
"Then why is Qiao Junlin so cold to his own father?"
"Who knows."
"Is it possible that I just looked a little like a human being and now I can't even look down on my newborn father?"
"His father's behavior is really embarrassing."
"On the contrary, he is not a very familiar person, so he is a little too warm."
"After all, that's his father."
"I think his younger brother is quite well-behaved.
He doesn't look like he has a straight face all day long, but he looks like someone owes him money and refuses to pay him back."
"Boring and utilitarian, it's really unpleasant."
The car Qiao Junlin was riding in was at the front of the queue.
Naturally, he didn't know what the people behind him were talking about.
Even if he knew, he probably wouldn't give these two people any expression. gd1806102:
