Since Yang Reform got the sailor, a matter in his heart has only been put down, however, more important things need to be prepared, now Songshan Fort can be fought hard, maybe it will be broken that day, this landing, you have to prepare immediately, you have to be ready to rescue at any time, so, it is even busier.

It is impossible for Yang Reform to go into battle in person, but even if Sun Chengzong is asked to supervise the division, Yang Reform is still not at ease, so he has made a lot of deductions from the General Staff.

"Two million silver coins......" Yang Reform bared his teeth, Yang Reform was going to the platform today, and asked Sun Chengzong and Qin Liangyu to study the combat plan, and took the time to correct the students' "homework", and saw the homework reported by a student, claiming that to build a seamless road from Beijing to Tongzhou, at least two million silver coins, which had to levy some conscription, otherwise, it would have to be more expensive, Yang Reform looked straight at it, and this silver was too worthless, so that Yang Reform's enthusiasm for building roads was instantly poured with a bucket of ice water.

"Your Majesty......" Wang Chengen asked with concern, looking at the emperor baring his teeth, Wang Chengen thought that the emperor was uncomfortable, or that he had a toothache.

"It's okay, it's okay...... Yang Reform hurriedly said, and while talking, he looked at the student's "homework", but it was handed in by Liu Mao, it stands to reason that this Liu Mao will not talk nonsense now, but why is this road so expensive?

According to this cost, Yang Reform did not dare to easily say that large-scale road repair, according to two million silver coins, forty miles, a mile of road actually cost 50,000 silver coins, according to a mile of road 500 meters, one meter to a hundred silver coins, if according to a meter of road six or seven square calculations, this square has to cost more than a dozen silver coins, of course, if to the slate, a square to five to six stone slabs, the price of a slate, is also two or three silver coins, really expensive, however, this slate, are quite thick slate, Guaranteed to be used for more than a hundred years, once paved, it can be used for many years, and the price can not be all calculated to the slate, this road is also three layers, the lower layer is the stone, the third layer is the triple soil, the third layer, is the stone slab, this is the highest level of the Ming Dynasty's road, if the ditches, bridges, trees on both sides of the road are also counted. Speaking of which, two million silver coins are not expensive, after all, this slate is mined from the mountain, and it has to be transported for dozens of miles, or even hundreds of miles to the place where the road is built.

Although this road is very expensive, Liu Mao also swore that it could be used for at least a hundred years, Yang Reform calculated, if this kind of stone road was laid in the city, forty miles, it would be possible to pave two roads six or seven meters wide in the north and south of Beijing, and the north and south of Beijing were ten kilometers......

Of course, if it is to repair the road from Beijing to Tongzhou today, it is much cheaper, tens of thousands of taels of silver, just pull a little mud to fill the pit, repair the bridge is to repair it, it doesn't take much money at all, if it is a road of Sanhe soil, it is slightly more expensive, you have to pave the stone on the basis of the road today, and then pave a layer of Sanhe soil on the stone, and calculate it, it will also cost three or four hundred thousand silver coins.

Yang reformed to understand, why the ancient times have been the levy as an important supplement to the tax, why the ancient project cost is so low, if all levy and issue levy levy, then the project cost is much lower, as long as you pay some money to support those who do the levy of the people, no slate, go to the mountains to pick, no carriage, build your own, no steel drill, send your own people to make iron, no lime, burn yourself, no tools, wood, you can do it yourself, cut it yourself, so that you can overwhelm the lowest cost of the project, Unless there is no need for less, they will buy it with silver, such as grain and salt, and in fact, even grain and salt can be mixed. Yang Reform saw the tears running, and summed up the Ming Dynasty's projects in one sentence, that is, "do it yourself, have enough food and clothing". …,

Now Yang Reform plans not to use forced labor, but to directly build roads according to commerce, which is simply to find guilt for himself, and the cost is very high.

The sad Yang Gai opened the homework of other students, and Sun Yuanhua mentioned that the work of burning stones was already a bit eyebrow-raising.

It's not how lucky Sun Yuanhua is, but Yang Reform has already explained, in the steelmaking meeting, Yang Reform asked Sun Yuanhua to take the stones that can be refined in the world to take a look, therefore, Sun Yuanhua has a clear understanding of the types of stones in the world, what kind of stone has the basic use, what is the thing burned, Sun Yuanhua has a rough eyebrow, and now the emperor asked him to burn lime from those stones, and it is comparable to granite, he has a lot of experience, and only then has a general direction, therefore, Yang Reform asked Sun Yuanhua to burn cement, but Sun Yuanhua quickly touched the edge of the cement.

"Natural cement?" Yang Reform looked at the things described in Sun Yuanhua's operation, and it was basically certain that Sun Yuanhua burned natural cement, this kind of "cement" that only needs one kind of ore to burn, Yang Reform remembers, there are only a few, from the description of the ore and the excavation ground, it is natural cement.

This kind of cement, it is impossible to pave the road, that is, it is okay to make adhesives, especially to pave sewers or something, what is that, that is, the mark is too low, and it will be crushed in a few days when it is used to repair the road.

Yang reformed for a while, for how to produce cement on a large scale, it is a headache, in the era of no steam engine, can only rely on water conservancy, animal power, manpower, to produce cement on a large scale, that is really a luxury.

"What I want to say to the Qing family is the summary and refining of experience, and I have repeatedly instructed the Qing family to record the refining process, that is, for this ,...... I don't know if the Qing family knows the "Compendium of Materia Medica", Li Shizhen will be the world's medicinal herbs, classified according to the program, respectively recorded the use of various medicinal materials, medicinal properties, color, how to obtain, how to concoct, and even with pictures, I think this is good, for the world's medicinal materials, there is a sense of clarity, more convenient for future generations to understand and learn, there is an immortal merit, Sun Qingjia may wish to learn from Li Shizhen, the world's ores are also classified, sub-outlined, arranged into a book, respectively, recorded their characteristics, functions, colors, The shape, where it is obtained, what can be fired, all kinds of changes at various temperatures, so that the world's ores will be clear at a glance, and future generations will have to learn, and it will be easier to ......" Yang Reform put aside some distractions and began to write his own criticism, although the matter of road construction is not eyebrow-raising, but the basic work of these scientific research must be guided by Yang Reform.

“…… Regarding the kind of stone that the Qing family said, I think it's not bad, so how to burn it on a large scale, and how should the Qing family do it? I plan to build a large number of civil works, once started, the demand for this kind of thing must be huge, a little production, it will definitely not work......" Yang Reform set a tone for the development of the mining industry, or began to sell cement.

“…… Shi Kefa also needs a large number of this kind of stone to build Shanghai New City in Shanghai, which is used as a binder, how to reduce the cost of firing, and the Qing family must work hard to ...... "Yang Reform wrote another paragraph, the cement is out, but it is used to pave the road, that is not expected, but it may be okay to use it as a binder, and it is much stronger to repair a house than to use lime as a binder, Yang Reform wants to promote cement in the new city of Shanghai, and is ready to build a real "new Shanghai". With cement, at least several floors of buildings can be repaired, Yang Reform has seen a lot of buildings built with bricks and wood, using cement adhesives, floors are made of wood, even in the 21st century, this kind of buildings are not uncommon, once cement is applied on a large scale in the field of construction, even the early 20th century buildings can be embodied, once Shanghai uses cement, a new Shanghai with the architectural characteristics of the early 20th century, can be embodied in the Ming Dynasty, for the course of history, will be a great promotion. …,

“…… A few days ago, I asked about the cost of paving the stone road, it is really expensive, and I am also sighing, so I may build the road with Sanhe soil, which is much cheaper, but the road of Sanhe soil is not condensed enough, afraid of water, and not ideal,...... I thought, if the road of Sanhe soil can be condensed better, it would be good, maybe it can be unsatisfactory, barely usable, the Qing family might as well try to take the Sanhe soil to burn to see if there can be any changes, I think, other soil mixed together is still mud, but Sanhe soil mixed together, but obviously changed a lot, maybe, there will be any surprises I can't say...... "Yang Reform is not afraid of trouble, write a long paragraph, now Sun Yuanhua there is the process of burning cement, is still exhausting a single ore, To wait until two or three kinds of substances are mixed to exhaustively, I don't know how to go to the Year of the Monkey, Yang Reform is in a hurry, and directly named and burned Sanhe soil, which is actually the raw material for burning cement, and Yang Reform is ready to open the golden finger.

Shanghai has already started construction, is a large-scale brick burning, a large number of buildings are about to rise from the ground, but to build the new Shanghai into a classical Chinese new city, or to build Shanghai into a new city with the characteristics of the 20th century architecture, Yang Reform very clearly chose to build Shanghai into a new city with the characteristics of the 20th century, therefore, cement is necessary, and directly out of the "Portland" cement, this epoch-making cement, not natural cement.

After writing the comments to Sun Yuanhua, Yang Reform turned over the "homework" from Yan'an Mansion again, the cement road is hopeless, but the asphalt road is good news, that is, Yan'an Mansion is too far away from here, and it is too far from the economic center.

“…… I heard the Qing family talk about the benefits of the oil residue road, very surprised, that is, not afraid of water, and not afraid of grinding, walking on it, there is a soft feeling, I thought, this kind of road, may be the road I want, the Qing family might as well send some oil residue over, I want to see for myself what this oil residue pavement, what is it...... "Yang Reform gave up the stone road, but also denied the cement road, for the time being, can only still use Sanhe soil to build the road, or directly repair the mud road, the current road repair. Instead, the asphalt road is regarded as a difficult project.

“…… I inquired about the price of oil, the Jingshi lard cost sixty or seventy wen a catty, and the clear oil also cost more than thirty wen, and the lamp oil of the Qing family should be as low as possible, or twenty wen, or fifteen wen, and strive to reduce the price of lamp oil to about half of the clear oil, and 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 as much as possible. Don't waste it, except for what I said before to pave the road to Yan'an Mansion, I am ready to pave the road to Beijing, you can take the waterway in the south, try it through the Yellow River, although it is not satisfactory, it is also a road...... "Yang Reform wrote a comment to Li Yanyi of Yan'an Mansion.

Since the cement road is not expected, the stone road is not even more expected, and the road of Sanhetu is not satisfied, then there is only the asphalt road, the asphalt road, the oil production must be raised, Yang Reform is ready to further subsidize the oil industry, and the oil industry must be raised if it loses money, according to the cost of the stone road, it will cost 2 million silver coins for 40 miles, if you use these 2 million silver coins to subsidize the oil industry, a pound of oil will be subsidized for 5 or 10 yuan, and 2 million silver coins can subsidize 300 million catties of lamp oil, and the oil output can reach 100,000 tons at once.

The annual output of 100,000 tons is a behemoth in the Ming Dynasty, in addition to the obvious role of the local driving force, that is, the promotion of the oil industry is particularly obvious, the by-products of oil, will gradually appear in people's field of vision, such as the ink extracted from the oil, such as lubricating oil, such as asphalt, etc., the oil industry will develop rapidly.

Yang Reform corrected a breath, felt that his arms were a little sore, shook his arms, carefully took stock of his own decision, his own correction of the "homework", can be regarded as the Ming Dynasty for many years to set the tone for the development of the Ming Dynasty in the future, thinking of Shanghai in the twentieth century appeared in the Ming Dynasty, thinking of the asphalt road paved to the door of his house, all kinds of carriages galloping on it, Yang Reform can't help but be proud.

"Your Majesty, it's time to go to the platform?" Wang Chengen smiled when he saw that the emperor was there alone to approve things, and after a while, he didn't mean to leave, and hurriedly 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.

"Oh......, I know, let's go ......" Yang reform's dream was broken, returned to reality from infinite reverie, hurriedly closed the notebook, put it away, locked it tightly, and prepared to go out ......,
