Chapter 549: Choosing the Road

Since Yang Jing got the navy, he had let go of a matter in his mind. However, more important things need to be prepared. Now Songshan Fort is very fierce, and it may be possible to be broken that day. This landing requires preparation immediately and to be prepared for rescue at any time, so it is even busier.

Yang Jingwei could not have taken action personally, but even if Sun Chengzong was asked to supervise the army, Yang Jingwei was still worried and asked the General Staff to do a lot of deductions. Yang Jingwei would not say anything else, at least he would have to see the possibility of victory in deductions.

"Two million silver coins..." Yang Jing grinned. Today, Yang Jing was preparing to go to the platform and asked Sun Chengzong and Qin Liangyu to study the combat plan. He took the time to correct the students' "homework". When he saw the homework reported by a student, he claimed that he would build a road with seamless connection of stone slabs from Beijing to Tongzhou, which would cost at least two million silver coins. This would require some corvee service, otherwise it would have to be more expensive. Yang Jing grinned. This money was too worthless, and Yang Jing's enthusiasm for building roads was instantly poured into a bucket of ice water.

"Your Majesty..." Wang Chengen asked with concern. Looking at the emperor's teeth, Wang Chengen thought the emperor was feeling uncomfortable or had a toothache.

"It's okay, it's okay..." Yang Jing said quickly, while also looking through the student's "homework", but it was handed over by Liu Mao. Logically speaking, Liu Mao would not talk nonsense now, but why is this road so expensive?

According to this cost, Yang Jing did not dare to easily say that a large-scale road construction would be built. Just calculated based on 2 million silver coins. Forty miles, a mile would actually cost 50,000 silver coins. One mile would cost 50,000 silver coins. One mile would cost 100 silver coins. If one mile would cost six or seven square meters, this square would cost more than a dozen silver coins. Of course, if one slab reaches a stone slab, one square would cost five to six stone slabs. The price of one stone would be two or three silver coins. It would be really expensive. However, these stone slabs are quite thick, which would be guaranteed to be used for more than a hundred years. Once paved, it would be very durable.

Of course, the price cannot be counted on the stone slab. This road is also three layers. The lower layer is stone, the second layer is three-layer soil, and the third layer is stone slab. This is the most advanced road in the Ming Dynasty. If the ditches, bridges, trees and other sides of the road are also included. Speaking of which, two million silver coins are not expensive. After all, the stone slab was mined from the mountain and had to be transported dozens of miles or even hundreds of miles to reach the road construction site. There were no heavy machinery in ancient times, and it was all artificially dug and manual transportation. The project cost was so expensive, so Yang Jing could understand.

Yang Jing was so expensive that he saw that this top road was so expensive. Although this road was very expensive, Liu Mao also swore that it could be used for at least a hundred years. Yang Jing calculated that if he paved such a cost of stone road in the city, forty miles, he could pave two six or seven meters wide roads in the north and south of Beijing. Beijing was ten kilometers north and south. If he wanted to pave such stone roads in Beijing, and all the sewers...

Of course, if it is to repair the road from Beijing to Tongzhou, it will be much cheaper, tens of thousands of taels of silver, just pull some mud to fill the pit and repair the bridge, it won’t cost much. If it is a road from Sanhedi, it will be a little more expensive. You have to lay stones on the basis of the road today, and then lay another layer of Sanhedidi on the stone. In total, it will cost 300,000 to 400,000 silver coins.

Yang Jing understood why corvee labor was always regarded as an important supplement to taxes in ancient times, and why the cost of engineering in ancient times was so low. If all corve labor was levied, the cost of engineering was much lower. Just spend some money to support the civilians who did corvee labor. There were no stone slabs, I went to the mountains to pick them, no carriages, no steel drills, I sent people to craft iron, no lime, burn them, and I could make them all by myself and cut them. In this way, the cost of engineering can be minimized, unless it is necessary to buy them with silver, such as grain, salt, and in fact, even grain and salt can be mixed. Yang Jing burst into tears when he saw that, and summed up the project in one sentence in the Ming Dynasty, that is, "do it yourself and have enough food and clothing."

Now Yang Jing plans to not use corvee labor and do it directly according to commercial road construction, which is simply a cause for his own suffering, and the cost is extremely high.

The sad Yang Jie looked at the homework of other students again. Sun Yuanhua mentioned that the work of burning stones was already a little clear-headed.

It’s not how lucky Sun Yuanhua was, but Yang Jing had already explained that when the steelmaking time, Yang Jing asked Sun Yuanhua to refine all the stones that can be refined in the world to see. Therefore, Sun Yuanhua had a clear understanding of the types of stones in the world. What kind of stones have the basic uses and what they burned out? Sun Yuanhua already had a general idea. Now the emperor asked him to burn lime from those stones, which was comparable to matsushi. He had a lot of experience, and only when burned, he had a general direction. Therefore, Yang Jing asked Sun Yuanhua to boil cement, and Sun Yuanhua quickly touched the edge of the cement.

"Natural cement?" Yang Jing looked at what Sun Yuanhua described in his work and was basically sure that what Sun Yuanhua burned was natural cement, which only requires one ore to burn. Yang Jing remembered that there were only a few types. Judging from the description and excavation of ore, it was natural cement.

This kind of cement cannot be paved, that is, it is okay to be used as adhesives, especially for laying sewers or something. What is it? The mark is too low and it will be crushed if it is used to build a road for a few days.

Yang Jing looked at it for a while and was even more troublesome about how to produce cement on a large scale. In the era without steam engines, it was really a luxury to rely on water conservancy, animal power and manpower to produce cement on a large scale.

"What I want to say to the Qing family is the summary and refinement of experience. I have repeatedly told the Qing family to record the refining process, which is for this... I don't know if the Qing family knows or not. Li Shizhen classified the herbs in the world, classified them according to the outline and the title, and recorded the uses, medicinal properties, colors, how to obtain, how to prepare them, and even included pictures. I think this is good. It has a clear sense of the world's medicinal materials, which is easier for future generations to understand and learn. It has a great achievement. Sun Qing family might as well learn from Li Shizhen and classify the world's ore, divided into outlines, and arranged them.

The book is made to record their characteristics, functions, colors, shapes, and what they can be burned, and various changes under various temperatures. In this way, the world's ore will be clear at a glance, and it will be easier for future generations to learn... In addition, the text should be as plain as possible so that they can understand..." Yang Jing put aside some distractions and began to write his own comments. Although there is no idea about building roads with cement, these basic scientific research work must be guided by Yang Jing. Yang Jing once again mentioned the importance of summarizing experience and refining experience, and is preparing to further expand the experience summary and purification work of the metallurgy industry.

"...I think the stones mentioned by the Qing family are not bad. So, how to burn them on a large scale, what should the Qing family do? I plan to build a large-scale construction. Once it starts, the demand for such things will definitely be huge, and some output will definitely not work..." Yang Jing still started to organize cement.

"...Shi Kefa also needs a lot of this kind of stone to be used as adhesives to build a new city in Shanghai. How to reduce the cost of firing? The Qing family needs to work hard..." Yang Jing wrote another paragraph. Cement has come out, but it is no longer expected to be used to pave the road. It may be okay to use it as an adhesive. Building a house is much stronger than using lime as an adhesive. Yang Jing wants to promote cement in the new city in Shanghai, preparing to create a real "new Shanghai".

With cement, at least several floors of buildings can be built. Yang Jing has seen many buildings built with bricks and wood, using cement adhesives, and floor slabs are made of wooden boards. Even in the 21st century, such buildings are not uncommon. Once cement is applied on a large scale in the field of architecture, even buildings in the early 20th century can be realized. Once Shanghai uses cement, a new Shanghai with the characteristics of the early 20th century can be realized in the Ming Dynasty, which will be a great improvement for the historical process.

"...I asked about the cost of paving stone roads a few days ago. It was really expensive. I sighed. Therefore, I might use Sanhedi soil to build roads, which is much cheaper. However, the Sanhedi soil roads are not condensed enough, and I am afraid of water and not ideal enough... I thought, if the Sanhedi soil roads can be condensed better, that would be great. Maybe it can be unsatisfactory and can be used barely. Your family might as well try to use Sanhedi soil to burn it to see if there is any change. I think other soils are mixed together.

It was mud, but the three-mix soil mixed together had obviously changed a lot. Perhaps, there would be no surprises..." Yang Jing was not afraid of trouble and wrote a long paragraph. Now the process of burning cement in Sun Yuanhua was still exhausting the single ore. He had to wait until two or three substances were mixed and exhausted. He didn't know that it would burn until the year of the monkey and horse month. Yang Jing was anxious and directly called the burning of Sanhe soil. This three-mix soil was actually the raw material for burning cement. Yang Jing was ready to open the golden finger.

Construction has started in Shanghai, and bricks are being burned on a large scale. A large number of buildings are about to rise up. Instead, we will build the new Shanghai into a new city in classical China or a new city with the characteristics of 20th century architecture. Yang Jing knew very well that he wanted to build Shanghai into a new city with the characteristics of 20th century. Therefore, cement must be produced, and epoch-making cement such as "Portland" cement should be produced directly, rather than natural cement.

After writing the comments to Sun Yuanhua, Yang Jie turned on the "work" from Yan'an Prefecture. There was no hope for cement roads, but the asphalt road was good news. Yan'an Prefecture is too far from here and too far from the economic center. The determination and perseverance that needs to be made with asphalt is definitely not something that ordinary people can think of.

"...I was very surprised when I heard the benefits of oil residue building roads in Qing's family. I was not afraid of water or crushing. When I walked on it, I felt soft. I thought that this kind of road might be the way I wanted. Qing's family might as well send some oil residue over. I want to see what the oil residue paving is like in person..." Yang Jing gave up the stone road and denied the cement road. For the time being, he could only use Sanhedi soil to build the road, or directly repair the mud road, and repair the current roads. Instead, he regarded asphalt roads as a key project.

"...I asked about the price of oil. The price of lard in the capital requires sixty or seventy cents per pound, and the cleaning oil costs more than thirty cents. The lamp oil of the Qing family should be as low as possible, either twenty cents or fifteen cents. We should try to reduce the price of lamp oil to about half of the clean oil, strive to occupy the market of lamp oil as quickly as possible, and strive to expand the market at the fastest speed, and increase the sales of lamp oil with the greatest possibility. As for the loss, it is okay. I will make up for the carriages needed by the Qing family. I will instruct the carriages to replenish as soon as possible, and do not waste the oil residues obtained. In addition to the paving road to Yan'an Prefecture, I will prepare to pave the road to the capital. You can take the waterway in the south and try it through the Yellow River. Although it is not satisfactory, it is also a road..." Yang Jing wrote a comment to Li Yanyi of Yan'an Prefecture.

Since cement roads are not expected, stone roads are not expected, and Sanhedi soil roads are not satisfied, then there is only one way to give birth to asphalt roads and give birth to asphalt roads, and oil production must be increased. Yang Jing is preparing to further subsidize the oil industry, and even if you lose money, you have to build the oil industry. According to the cost of stone roads, two million silver coins will cost for 40 miles. If you use these two million silver coins to subsidize the oil industry, one pound of oil will be subsidized by five cents or ten cents, and two million silver coins can subsidize 300 million jin of lamp oil, and the oil production can reach 100,000 tons at once.

Annual output of 100,000 tons was considered a huge monster in the Ming Dynasty. In addition to its obvious driving effect on the local area, it was particularly obvious to promote the oil industry. The by-products of oil will gradually appear in people's sight, such as ink extracted from oil, lubricating oil, asphalt, etc. The oil industry will develop rapidly.

Yang Jie was so angry that his arms were sore. He shook his arms and carefully took stock of the decisions he had made. The "homework" he corrected this time set the tone for the development of the Ming Dynasty in the future. When he thought that Shanghai appeared in the Ming Dynasty in the 20th century, and when the asphalt road was paved to his doorstep, various carriages were flying on it, Yang Jie couldn't help but feel proud.

"Your Majesty, it's time to go to the platform?" Wang Chengen laughed when he saw the emperor criticizing things alone there. After a while, he had not set off, so he quickly reminded the emperor that it was time to go to the platform. Sun Ge Lao and Qin Liangyu had been waiting for a long time.
