"How do you study these things!"

Li Mu complained silently in his heart, just about to say it, but he swallowed it again when he reached his mouth.

He realized the problem, and it was not a problem that no one studied or not. Instead, the process of history should be like this, slowly and little by little.

From his perspective as a time traveler, he knows what these things will look like after they are formed. It is like a college student calculating addition, subtraction, multiplication and division. It will be difficult for him to understand why such simple questions can be done wrong. But for a seven or eight-year-old primary school student, this is the most difficult question he faces. He has to wait until he passes through elementary school, goes through middle school, and goes to college, and looks back, and then he will feel simple.

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

After reading from beginning to end, Li Mu summarized that if he continues according to the current situation, this Dongcheng Arsenal would probably not be able to produce anything useful in a short period of time.

Looking at the hard-working but unwilling eyes, Li Mu sighed and said, "Let's do this, let's put all the projects in your hands first - go home to celebrate the New Year. When the first month of the year comes, you will follow me to Luoyang. I will teach you if I have time."

After saying that, Li Mu turned around and left. He couldn't stand this place anymore and could not stay for too long.

Li Mu turned around and walked away, and the people behind him were already whispering. They were all the best craftsmen in the Tang Dynasty, from all over the world. Many of them were not from the Ministry of Works and did not understand Li Mu's ability. Seeing that Li Mu was so angry, some people were dissatisfied and muttered in a low voice, thinking that Li Mu was just a lucky minister who had gained his current status with His Majesty's favor and dared to speak vainly? Does he know how to forge? Do he know how to build weapons? As soon as he was halfway through his words, a craftsmen from the Ministry of Works stood up and scolded him sternly. Both sides started fighting and went home with blue and swollen faces.

The news soon reached the palace. After Li Shimin heard it, he just laughed. Eunuch Gao was confused and asked, "Why is Your Majesty laughing? The fight within the East Factory should be severely punished."

"Severe punishment?" Li Shimin waved his hand and said, "What I want to see is this situation. Both sides compete and make progress quickly. I thought Li Mu would lose his temper, but now it seems that he has grown up."

Eunuch Gao seemed to understand but he remembered the duty of the inner officials and did not ask too much.

Li Shimin carried his hands on his back, looked at the sunset outside the window and said to Eunuch Gao: "Let the Imperial Hospital send a few doctors to visit the condition. The people from the Dongchang are all very valuable talents, so don't really have anything to do. By the way, you can also whine a few words from them, don't say it too ruthlessly. Those who have opinions about Li Mu, and those who are trying hard to protect Li Mu, have all recorded their names and let the Dongchang men pay more attention to anything unusual and report to me."

"promise."

Eunuch Gao responded, and he became increasingly unable to guess Li Shimin’s thoughts.

...

When he returned home, Li Mu became worried. He now faced two choices, either, he opened his golden fingers, turned the skills in the system into secrets, and then taught them to these craftsmen. If he did this, the various industrial technology levels of the Tang Dynasty would grow leaps and bounds. But there were also disadvantages to doing this, that is, if he did this, he would likely release a demon. Li Shimin was not a monarch who guarded the city, and his ambition was extremely ambition. Li Mu could not imagine if he did this, would Li Shimin become a militaristic, and would he become like Qin Shihuang in the past, wanting to occupy the place where he looked.

If Li Mu was an angry young man, he would think that there was nothing wrong with this. However, after he came to the Tang Dynasty, he contacted the people of the Tang Dynasty and felt the living people around him. He could clearly feel that most of the people were just thinking about spending a few days of peace. They did not have such great ambitions and ambitions. Even if they were excited in front of Chengtian Gate that day, it was just the effect of deliberate incitement. Those fanatical people would not think about going to the battlefield and truly face the blood. They would not like the days when they were in the battlefield.

Li Mu didn't like it either, and he even felt that it was unnecessary to do so. Because the world, materials, resources, and population in the early Tang Dynasty were far from saturated. This world could easily raise the population of the whole world. In this case, the purpose of aggression was only invasion. For the ruler's own selfish desires, tens of thousands and hundreds of thousands of people sacrificed their lives. Li Mu did not decide this calculation.

Life is just a few decades, and what will happen in the future has been written in history books. That is a matter of hundreds of years later and has nothing to do with the present. Li Mu doesn't want to think about it. What he wants to do now is to vigorously develop the economy, vigorously do infrastructure, and truly change the hard days of the people. He has no intention of thinking about other things.

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

Before he finished speaking, Li Mu stopped. 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 came over from the side. Li Mu looked up and saw that it was Wei Yingluo. He showed doubts. Wei Yingluo explained: "It's almost the Spring Festival and I've been staying at home and haven't gone out. Today, when Pearl came home, he pulled me out. We walked around the East City and saw a few beautiful jewelry, which were not expensive, so I bought it for my sisters."

Listening to Wei Yingluo say this, Li Mu was overjoyed: "Have you met Qiaoqiao? What did she say?"

Wei Yingluo began to pretend to be stupid and said, "Mrs. said that the hairpin looks good, but she also told me not to spend money." She spread her hands and said to Li Mu, "I have spent all my monthly salary, and I have no money now."

"Oh." Li Mu reached 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 housekeeper? If you don't have money, you just need to withdraw it yourself."

Wei Yingluo shook her head and said, "After Zhien comes back, I will hand over all the accounts to her."

"Oh..." Li Mu suddenly realized that Wei Yingluo was handing over the power. Because when Li Zhien was there, she was the one who managed the account at home. It took Wei Yingluo more than half a year before Li Zhien went to Silla. Now that Li Zhien is back, she returns the account book, which is not only a way to show her attitude, but also considers Qiaoqiao's feelings. After all, among all wives, Qiaoqiao and Li Zhien are the closest.

At the same time, Qiaoqiao's acquiescent to this matter also showed Qiaoqiao's attitude. She should still hope to see the accounts in Li Zhien's house, so that she would feel more at ease. And Wei Yingluo's positioning may be a secretary?

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

It seems that they have already made arrangements, so don’t get involved with it.

"I remember before I came back from Luoyang, I asked you to collect a piece of information for me, which was about the cost of road construction. Did you bring it here?"

"Ah, I've brought it here." Wei Yingluo nodded and said, "In a box, I'll go to the warehouse to look for it." As he said that, he turned around and walked out. After a while, Li Mu heard the footsteps behind him, thinking that Wei Yingluo had returned, but when he listened carefully, he felt something was wrong. The footsteps were not like that. When he looked back, he saw that it was not. Li Zhien was holding a candied fruit in his mouth and looked at him with a smile.

"Thank you."

"Oh," Li Zhien was a little embarrassed, blushed and silenced his nose, leaned into Li Mu's ear and whispered: "Actually, they are selfish."

"What?"

Li Zhien leaned into Li Mu's ear and muttered a few words. Li Mu was amused and crying, and said, "What kind of goods am I? Is it still used for trading?"

"No matter!" Li Zhien grabbed a handkerchief from his sleeve, with words on it, raised her, and said, "No one can regret it if he signed the contract." After that, she stuck out her tongue and rushed Wei Yingluo to escape before coming back.

After a while, Wei Yingluo came back with what Li Mu wanted. Of course, Li Mu would not show any abnormality. He took the documents in Wei Yingluo's hand and started to look through them.

The information was sorted out by Wei Yingluo. Wei Yingluo naturally remembered that Li Mu looked through her and said: "The most common ground is made of solid rammed earth. This method is the lowest cost and only consumes manpower. But this kind of road is built like a road, and it will be bumpy when rain falls. However, it is the most widely used by the people. It is usually repaired before the rainy season, and repaired every year. A little better, there is a place backing the mountains or rivers, where there are gravels and gravels, and then tamp them on the road. The road built in this way is a little stronger than a road with only rammed earth, but it is not a long-term solution."

"Usually, government officials or local tribes use cooked soil to build roads. Cooked soil means frying the soil over fire, so that there will be no insects or grass, and the foundation will be more stable. Further, it is to use soil to burn blue bricks to pave the roads, which is relatively firm and has no heavy-loaded cars. There will be no problem in three to five years. Of course, the cost is the highest, and the best, and it is still the stone slab. It is just that mining is not easy and the output is low. Apart from building palaces, few people can afford blue slabs."

"At present, the best way to build a road is the 'three-mix soil' you invented. The price is lower than that of blue bricks, but the durability is greater than that of blue bricks. But even if it is built like this, it costs 3,000 guan per mile. It costs about 300,000 guan to build a road, which is a result of savings in all aspects."

“It’s too slow, it’s still too slow!”

After hearing Wei Yingluo say it, Li Mu finished reading it and murmured to himself. He said it was too slow, not because the road was built too slowly. In fact, hundreds of miles from Chang'an to Luoyang and completed within a few months, it is already a miracle. The reason he said it was too slow is that the road of Sanhedi is also inseparable from that old problem. When natural disasters such as rain and landslides occur, the road will still be damaged. It looks quite good now, but maybe it may take only one or two years to survive, and there will be problems in each section. By then, people have become accustomed to the convenience and speed of Chidao. Once a section of the road has a problem, Chidao cannot be used, and the losses caused will definitely be very large.

It has to come out like a way.

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

The first type is sand and gravel road. First dig the ground, then replace the pellets, that is, large pieces of stone, and then slowly reduce them. In the end, the road surface is covered with fine sand and 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 main roads still use this method. This method has certain feasibility, but it needs to be used in places with stones and places without stones. Needless to say, it will definitely not be implemented. How can we transport stones without trucks in this era? Where there is stone, it depends on what stones it is. No matter how much granite there is, it cannot be crushed in this era and cannot be used.

The second type is the asphalt road that is commonly used in national highways. However, in this era, there was no oil exploitation, and asphalt, as an appendage to oil, naturally did not have it. The natural asphalt has too few quantity and cannot form a scale.

The third type is cement road.

Li Mu has been thinking about cement for a long time. He has always wanted to make cement, but he has never had time. The main ingredients of cement are very simple, and he knows the ratio. For example, the most common silicate cement is made of limestone and clay, which are broken, mixed and ground into raw materials, and then fed them into a cement kiln to calcinate them into clinker, and then grind them into an appropriate amount of gypsum to grind them. Li Mu doesn't know where to get two important products, limestone and clay.

In his time, cement was something that could be bought anywhere. He did not study where cement was produced. Although the resources of the Tang Dynasty were not developed, the territory was too vast. He could not explain to people what limestone was and clay was. To find a large number of these two things, it was like looking for a needle in a haystack. But no matter what, cement must be produced. Since it is something that is everywhere in more than a thousand years later, it must not be difficult to find!

Li Mu searched through his baby studio and finally found a sample of limestone and clay for him. He handed the sample to Mrs. Lu and asked her to come forward on his behalf to find these two things. Of course, for the sake of confidentiality, he also added seven or eight other things to confuse the public. Li Mu gave a reward of 10,000 yuan. The five people who provided the exact information could share this ten thousand yuan after verification.

Li Mu's every move was under the attention of all forces. Li Mu was looking for these things, and the major families, including the court, were also looking for them together. Some of them had been found, but they did not come to receive Li Mu's rewards, but studied privately what the use of these things was. Li Mu released the news, but the news was delayed, which made him very uncomfortable.
