After waking up after a sleep, the two of them drove the ox cart home. They passed by a pond and smashed the ice surface to wash their faces. They were completely energetic. The two of them drove the ox cart. When they passed by the market, they bought some rice and noodles for food. When they returned to the village, it was just the time to make lunch.

The old Song family is a family of five. In addition to the couple, there are two girls and one boy. The eldest girl is about to go out of the box and embroider the quilt for herself and prepares a dowry. Her little daughter is still young and is holding it in her arms. The only male, half-baby, is with him every day. First, he is able to do some work, and also afraid that she will become a lazy man at home and will not be able to bear the door in the future.

As soon as he entered the door, the youngest daughter saw it and immediately ran over happily.

"Dad, brother!" She waved her hand excitedly.

"Hey! Good daughter!" Old Song saw his little daughter, forgot all the fatigue. He left his son to carry things by himself, and hugged his daughter and entered the house. He was worried that his daughter would suffer from a cold. In this era, ordinary people said that if he had a cold, it would be no different from losing his life. Old Song secretly took out a piece of candied fruit from his arms and stuffed it into his little daughter's hand. The little daughter touched the candied fruit and hid it like a thief. This is the secret between father and daughter, and no one else knows it.

In fact, how could Lao Song be more favorable to the other side? He also prepared for his eldest daughter. The eldest daughter is about to get married and will meet less in the future. Although this candied fruit is not valuable, it is also the taste of the family. If a father can afford it, he will naturally not be stingy.

Xiao Song muttered and moved by himself with his fate. Although he was the only one who passed on his own, he never had such treatment.

"Damn your mother, how happy it's going to die!" Li Hua laughed and cursed, and threw a tile of knife-and-mud idea to reward those sluts.

Four kilograms of rice, two taels of oil, and one piece of "vinegar cloth".

This is today's harvest. For ordinary families, this is already too much. There is still a little extra money to save and get a dowry for their daughter.

There is a calf at home. Lao Song was planning to make some wood and build a calf cart. If they could have two calf carts, their income would double. If the calf didn't pull much goods, they could still get more than 30% or 40%. If the calf had accumulated a lot, it would not be a loss.

"I'm back, let's wash and eat." Old Song's wife Wang, seeing her husband and son coming back, felt relieved and greeted her father and father for dinner.

"Well, you have worked hard, too." Li Hua reached out and touched his wife's face.

Under the reflection of the fire in the pond, her face was blushing.

In fact, ordinary people do not have high requirements.

When they are not full, they are thinking about food and clothing. When they are full, they are thinking about eating better and dress better. The ordinary people of the Tang Dynasty have limited their needs.

Not only the Tang Dynasty, but also the past dynasties, including the era in which Li Mu traveled through time, were all the same. This is the idea of ​​most ordinary people, but if you break out of the scope of "people" and enter another level, the situation will be different.

Different vision, knowledge, insight, class, etc. will bring people more desires. In order to fill these desires, things that will cause deception and the strong will gradually happen.

The country finally ended from the previous cycle of reincarnation. What Li Mu thought about was how to make the next cycle come later and how to make the people live a better life.

Lantian County is its starting point.

...

It is impossible to achieve success in one go. There will always be many problems in the process. For example, what Li Mu is now working on solving is a problem that only when he is actually doing things can he encounter and cannot solve by theory.

At first, he found that Lantian County had coal, limestone, and kaolin. After meeting the conditions for cement production, he designated Lantian County as the location of the first cement factory. Everything was done according to the plan, but suddenly, the problem arose.

The coal in Lantian County has a shallow layer of several meters, and the quality of the coal in Taiyuan is comparable to that in Taiyuan, and there is no problem with it. However, after passing the surface layer, the quality of the coal below has dropped sharply. The sulfur content is large and there is a odor when burned. Two workers have fainted because of this. After Li Mu knew the situation, he ordered that only shallow layer of coal be dug for the time being. When using it, if you smell the odor, the fire will be extinguished immediately.

After the on-site investigation, the situation is very unoptimistic. If it is just coal from one place, the coal mine can be discarded. However, the result of the investigation is that about 80% of the coal mines here are in this situation. In a short period of time, due to the small output, it can be dealt with. However, if it is formed, it cannot be avoided no matter how long it is.

Therefore, this problem must be solved.

Li Mu habitually looked for solutions in the system, but he failed this time.

There was no applicable solution in the system. He searched several times and pulled the snake spirit out as an auxiliary, but he did not find a solution to the problem from the vast code.

This is the first time, and the system can't help at all.

Helplessly, Li Mu had to find a way himself.

After sifting through the memories of two lifetimes, Li Mu finally found a possible solution.

He vaguely remembered that when he first arrived at the orphanage, due to insufficient funds, the orphanage did not have a warmer. In order to prevent the children from being frozen, the old dean used a manpower truck to buy honeycomb coal. Then he mobilized the children to pick up branches together for heating.

In China in the 1990s, buildings were still rare. Most people lived in bungalows, burning stoves to keep warm. Honeycomb coal was the best-selling thing in winter, no doubt. Because the orphanage had no money, it could not buy much. So when it was not enough, the old dean would take them to pick up coal cores that others had not burned completely. The actual memory of coal in memory was limited to this.

Li Mu vaguely remembered that the old dean said about honeycomb coal. His original words were that honeycomb coal would be the best. Coal basins were difficult to use, but they could be used after they were made into honeycomb coal. And in his memory, honeycomb coal did not have too high odor.

Local honeycomb coal cannot contain sulfides. So it must have been treated to achieve this effect.

Considering that the economic situation was not very good at that time, honeycomb coal was popularized because it was cost-effective and affordable for ordinary people. Then, no matter how it was handled, the cost would not be very high, otherwise it would not be promoted.

Furthermore, since the technology of honeycomb coal can be expanded nationwide, the technical difficulties must be not high, at least there are no regional restrictions.

Combining these premises, Li Mu made a judgment that this thing can be made and not that difficult.

Li Mu remembered the shape of honeycomb coal. So the first step was to create a mold. He was a high-level blacksmith himself, so it was not difficult for him to create a mold.

If the mold has it, it is the material.

First of all, coal is certain. Some of the crushed coal balls are found. Then he found a way to glue the coal together. In Li Mu's memory, when the honeycomb coal was burned, even if the yellow mud was colored, there was no other thing, so he asked someone to dig the yellow mud, thaw it, and mix it with the coal balls, and then put it in the mold to press it into honeycomb coal.

No experiment was successful in one go, and Li Mu never thought that it might be successful in one go. However, this thing was that simple, it would be successful in one go. However, the burned residue was a bit large, and Li Mu adjusted the proportion again, increased the proportion of coal, reduced the proportion of yellow mud, and changed it to seven to three. The later residues broke as soon as they touched, and the effect was outstanding.

A very difficult problem in Li Mu's impression was solved so easily, giving him a feeling of hitting cotton with one punch. At the same time, he also understood why there is no honeycomb coal in the system. This thing is too simple. Anyone who is a little older can understand its composition. The most important thing is that after Li Mu graduated from university, the honeycomb coal has basically disappeared. It is rarely known to young people in the game. It is just a game, so there is no need to go to archaeology.

The problem was solved, but Li Mu was not satisfied with it.

Although the honeycomb coal he made was burned, it was similar to what he had seen in his previous life, but it was a bit difficult to ignite the honeycomb coal and was not so easy to burn. The honeycomb coal he remembered wanted to ignite with a cigarette butt, but there was very little smoke and dust. This shows that there must be things in the honeycomb coal that suppressed dust, and there were also substances specifically used to cause fire.

There is no reference for this. After Li Mu left the orphanage to go to school, he never saw honeycomb coal again.

So, another round of experiments.

Li Mu found all the relevant recipes in the system, copied them on paper, and asked someone to take them back to the Ministry of Works, the Ministry of Works, the Ministry of Internal Affairs and the Ministry of Foreign Affairs to prepare the materials according to the things listed on the list, and delivered them to Lantian County one by one.

Li Mu's list spread across the country within two days. Although no one knew what these things could be useful, as long as they were used by Li Mu, it would definitely be useful as long as they were branded.

Just grab something useful.

In less than three days, the markets in Chang'an City, Luoyang City, and the things on Li Mu's orders all rose by about three times. The only thing that remains unchanged is coal, because coal, a civilian resource, is sold at a price in winter, and without the clear text of the court, it is not allowed to raise prices at will.

...

After Sun Fujia returned to Chang'an, he spread all the news about the cement factory. There was nothing to hide, and he also received Li Mu's permission.

Coupled with the publicity of the Tang Daily, public opinion was immediately ignited.

"Do you know why the Marquis can build the factory so quickly?"

"Who doesn't know, it's just cement?"

"Cement!" the speaker sighed and said, "What's it like? I really want to see it with my own eyes."

In the past half a month, the topic of cement has spread throughout the streets and alleys, which has aroused the curiosity of the people.

First of all, coal is certain. Some of the crushed coal balls are found. Then he found a way to glue the coal together. In Li Mu's memory, when the honeycomb coal was burned, even if the yellow mud was colored, there was no other thing, so he asked someone to dig the yellow mud, thaw it, and mix it with the coal balls, and then put it in the mold to press it into honeycomb coal.
