"How did you study these things?"

Li Mu complained silently in his heart, and just wanted to say it, but the words came to his mouth and swallowed again.

He realized the problem, and it wasn't a question of who didn't study it. Rather, the course of history should be like this, moving forward slowly, little by little.

From his perspective as a time-traveler, he knows what these things will look like when they are formed, and it's like a college student doing addition, subtraction, multiplication, and division, and it would be difficult for him to understand why such a simple problem could still be done wrong. But for a seven or eight-year-old elementary school student, this is the most difficult topic he faces, and he will not feel easy until he has gone through elementary school, passed middle school, and reached university, and when he looks back.

Thinking of this, Li Mu put away his anxiety and continued to watch.

After reading it from beginning to end, Li Mu concluded that if it continues according to the current situation, this Dongcheng Arsenal may not be able to make anything useful in a short period of time.

Looking at a pair of hard-working and unwilling eyes, Li Mu sighed and said: "In this way, you put aside the projects in your hands first-go home to have a good year, and when the first month comes, you go to Luoyang with me, and I will teach you when I have time." ”

After speaking, Li Mu turned around and left, he couldn't stand this place anymore, and he couldn't stay any longer.

Li Mu turned around and left, and the people behind him were already whispering. They are all the best craftsmen in the Tang Dynasty, from all over the world, many of them are not from the Ministry of Industry, do not understand Li Mu's ability, seeing Li Mu's tone is so big, some people are not convinced, muttering in a low voice, thinking that Li Mu is just a fortunate minister, relying on His Majesty's favor to get today's status, and dare to speak out about guidance? Does he know how to black? Do you know how to craft weapons? As soon as he said half of the words, a craftsman from the Ministry of Industry stood up and reprimanded him sharply, and the two sides actually fought, and one by one they went home with blue skin and swollen faces.

The news quickly spread to the palace, and after Li Shimin heard it, he just laughed. Gao Gonggong was puzzled in his heart, so he asked, "Why is Your Majesty laughing?" The fight in the East Factory should be severely punished. ”

"Severe punishment?" Li Shimin waved his hand and said, "What I want to see is such a situation. The two sides are more energetic, and the progress is fast. I thought that Li Mu would lose his temper, but now it seems that he has grown up in the end. ”

Gao Gonggong seemed to understand whether he understood or not, but he also remembered the duty of the eunuch and didn't ask much.

Li Shimin put his hands behind his back, looked at the sunset outside the window, and said to Gao Gong: "Let the Tai Hospital send a few doctors to visit the condition." These people in the East Factory are all very valuable talents, but don't really have anything wrong. By the way, you also beat them a few words, don't say too harshly. Those who had opinions about Li Mu, as well as those who tried their best to defend Li Mu, wrote down their names, so that the fans of Dongchang could pay more attention to them, and report any abnormalities to me. ”

"No."

Gao Gonggong responded, and he couldn't guess Li Shimin's thoughts more and more.

……

When he returned home, Li Mu became worried. He is now faced with two choices, either he will open his golden finger and make all the skills in the system into cheats, and then pass them on to these craftsmen. In this way, Datang's various industrial technology levels will grow by leaps and bounds. But there is a downside to this, that is, if you do this, you are likely to release a demon. Li Shimin is not a monarch who defends the city, his ambition is incomparable, Li Mu dare not imagine, if he does this, Li Shimin will not become reckless, will he become like Qin Shi Huang back then, he wants to occupy all the places he sees.

If Li Mu was an angry young man, he would feel that there was nothing wrong with this. However, after he came to Datang, he came into contact with the people of Datang and felt the living people around him, and he could clearly perceive that most of the people actually just wanted to live a peaceful life for a few days, and they did not have so much ambition and ambition. Even if it was like that day, in front of Chengtianmen, the crowd was excited, but it was just a deliberate incitement effect. Those fanatical people, they will not think about going to war, and they will not like the day when they really face blood.

Li Mu didn't like it either, and even he felt that it was unnecessary. Because the world in the early Tang Dynasty, materials, resources, and population, were far from saturated. The world can easily feed the world's population. Under such circumstances, the purpose of aggression is only aggression, for the ruler's selfish desires, tens of thousands, hundreds of thousands of people will sacrifice their lives, Li Mu does not decide that this account is cost-effective.

Life is just a few decades, and what the future will be like has been written in the history books. That was hundreds of years from now, and it has nothing to do with the present. Li Mu also didn't want to think about it, what he wanted to do now was to vigorously develop the economy, vigorously do a good job in infrastructure construction, and truly change the hard life of the people. He didn't have the heart to think about anything else.

Li Mu pondered for a long time and said, "Yingluo, you help me put the information that you asked you to sort out some time ago-"

Before he finished speaking, Li Mu stopped, and he suddenly realized that this was Xiaoyao Valley, not Luoyang. Wei Yingluo would not appear behind him at any time and bring him the documents he needed.

Just when he was sad, suddenly, a hand stretched out next to him, Li Mu looked up, and it turned out to be Wei Yingluo. He looked puzzled, and Wei Yingluo explained: "It's almost the Yuan Festival, and I have been staying at home and not going out to wrap up." When Pearl came home today, she dragged me out. We walked around the East Market and saw a few beautiful pieces of jewelry, which were not expensive, so I bought them for my sisters. ”

Hearing Wei Yingluo say this, Li Mu's heart was full of joy: "Have you met Qiaoqiao?" What did she say? ”

Wei Yingluo began to pretend to be stupid, and said: "Madame said that the hairpin is good-looking, but she also told me not to break the bank." She spread out her little hand and said to Li Mu: "My monthly money has been spent, and now I have no money." ”

"Oops." Li Mu put his hand into his sleeve, exchanged a few gold bars from the system, put them in Wei Yingluo's hand, and said, "When did our family lack money?" Besides, aren't you a steward? If you don't have any money, you can just withdraw it yourself. ”

Wei Yingluo shook her head and said, "After Zhi'en comes back, I will hand over all the account books to her." ”

"Oh......" Li Mu suddenly realized that Wei Yingluo was handing over power. Because when Li Zhien was there, she was in charge of the family's accounts, and Li Zhien went to Silla for more than half a year, Wei Yingluo took her place, and now that Li Zhien is back, she returned the account book, which is not only to show her attitude, but also to take into account Qiaoqiao's feelings. After all, among all the wives, Qiaoqiao and Li Zhien have the closest relationship.

At the same time, Qiaoqiao's acquiescence to this matter also shows Qiaoqiao's attitude, she should still want to see Li Zhien take care of the family's accounts, so that she will be more at ease. And Wei Yingluo's positioning, maybe a secretary?

Li Mu looked at Wei Yingluo and did not continue to talk about it, but directly skipped it.

It seems that they have already arranged it, so don't follow it.

"I remember that before I came back from Luoyang, I asked you to help me collect a piece of information about the cost of road repair, did you bring it here?"

"Ah, bring it here." Wei Yingluo nodded and said, "In a box, I'll go to the warehouse to look for it." After saying that, he turned around and walked out, and after a while, Li Mu heard the footsteps behind him, thinking that Wei Yingluo was back, but after listening carefully, he felt that something was not right, the footsteps were not like it, and when he looked back, it was really not, Li Zhien had a candied fruit in his mouth, and looked at him with a smile.

"Thank you."

"Ouch," Li Zhien was still a little embarrassed, blushing and silencing his nose, leaning into Li Mu's ear and whispering: "Actually, people are also selfish." ”

"What?"

Li Zhien leaned into Li Mu's ear and muttered two words, Li Mu couldn't cry or laugh, and said, "What kind of goods am I?" Still traded and traded? ”

"No matter!" Li Zhien grabbed a handkerchief from his sleeve, with words on it, raised it, and said, "If you sign the contract, no one can go back." After saying that, she stuck out her tongue and ran away before Wei Yingluo came back.

After a while, Wei Yingluo came back with what Li Mu wanted. Of course, Li Mu would not show the slightest abnormality, he took the document in Wei Yingluo's hand and flipped through it.

The information was sorted out by Wei Yingluo, Wei Yingluo naturally remembered, Li Mu looked through it, she said: "The most ordinary ground is made of rammed earth, which has the lowest cost and consumes only manpower." But when this kind of road is built, it will be like a rain, and it will be potholes. However, it is the most widely used by the people, and it is usually repaired before the rainy season, and it is repaired every year. It is better to have gravel and gravel in the place near the mountain or river, and then tamp it on the road, so that the road built in this way is a little stronger than the road that is only compacted with soil, but it is not a long-term solution. ”

"Usually the government or local clans build roads, using cooked soil, cooked soil is to fry the soil with fire, so that there will be no insects or grass, and the foundation will be more stable. The further is to use soil to burn green bricks to pave the road, which is relatively firm, and there is no heavy-duty car, and there is no problem for three or five years. Of course, the highest cost and the best are still slates. It's just that mining is not easy, and the yield is low, except for building palaces, few people can afford to use bluestone slabs. ”

"At present, the best way to build a road is the 'Sanhe soil' you invented, the price is lower than that of green bricks, but the degree of durability is more than that of green bricks. But even if it is repaired like this, it will cost 3,000 yuan for one mile of land. It cost about 300,000 yuan to build the road, which is already the result of saving in all aspects. ”

"Too slow, still too slow!"

After Li Mu heard Wei Yingluo finish speaking, he also finished reading it and muttered to himself. He said it too slowly, not because the road was built too slowly, in fact, hundreds of miles from Chang'an to Luoyang, and it was built within a few months, which is already a miracle. He said that the reason why it was too slow was that the road of Sanhetu was also inseparable from the old problem, and when natural disasters such as rain and landslides occurred, the road would still be damaged. It's good now, but maybe it won't last a year or two, and there will be problems in each section. At that time, people have been accustomed to the convenience and speed of the road, once there is a problem in which section of the road, the road can not be used, and the loss will be very large.

Gotta come out like a way.

In the era in which Li Mu lived, there were three main forms of road construction.

The first is a gravel road. The ground is dug up first, then the pellets, i.e. large stones, are replaced, and then slowly reduced, and eventually the road surface is covered with fine gravel. The advantage of this is that the entire road surface is compacted and crushed, and it is not a problem to use it for five or six years without heavy loads. Many rural arterial roads still use this method. This method has a certain feasibility, but it has to be in a place where there are stones, needless to say where there are no stones, it will definitely not be implemented, how can you transport stones without trucks in this era? Where there are stones, it depends on what kind of stones, no matter how much granite there is, it can't be shattered in this era, and it can't be used.

The second type is asphalt roads, which are commonly used on national highways. But oil was not exploited in this era, and asphalt, as an appendage of oil, naturally did not. Natural asphalt is too small in quantity to form a scale.

The third type is the cement road.

Cement, Li Mu has been thinking about it for a long time. He had always wanted to get the cement out, but he never had time. The main composition of cement is very simple, and the ratio is also clear. The biggest problem is that he does not know the origin of the raw materials. The first is a gravel road.
