After the imperial court retreated from the court, everyone looked at Du Ruhui and was also pointing fingers, thinking that Du Ruhui was too ugly this time, and actually arranged his younger brother to serve in Menxia Province, which was too much. Pen ~ fun ~ pavilion www.biquge.info but Du Ruhui is also a dead pig is not afraid of boiling water, because he knows that he was used by the extraordinary this time, but what is even more cheating is how he was used, what is the purpose of Shi Bufan, so he doesn't know very much, this is the tragedy.

So since Du Ruhui knows that it doesn't matter how he explains, then no one else will believe it, so he simply won't explain, anyway, this time the benefits are in hand, and he has eaten the pies in the sky, so he is the biggest benefit. No matter what Shi Bufan wants, his old Du family has gained the greatest benefit, that is, to eat it quickly. If pie falls from the sky, then eat it quickly, don't be stupid and don't eat it, then it will be unlucky.

As for Shi Bufan, he chatted with Yan Liben, who had just been a businessman.

"Chief Shi Cao, what are you going to do this time?" Yan Liben asked.

Shi Bufan didn't explain, and said directly: "I plan to do some business with the Yan family in the future, and I can talk to Miss Qin from the Qin family's money house when the time comes." ”

"Miss Qin, oh!" Yan Liben understood.

Who in the entire Chang'an City doesn't know that Qin Jiarui is Shi Bufan's political white glove, who is responsible for dealing with some economic and other inconvenient things to come forward with, so it is Shi Bufan's political white glove, and she even gave birth to a son to Shi Bufan!

"Brother Yan, in the collection of materials for civil engineering, what do you say is the most difficult thing to collect?" Shi Bufan asked.

Yan Liben thought for a moment and said, "That should be a stone!" Yo Qiu is that the big boulder is too difficult to get, the big boulder is not only too heavy, but also a lot of difficult to mine, very labor-intensive. In many cases, it is because of the lack of large stones, so many projects cannot be repaired. ”

As an engineering family, Yan Liben still understands this aspect very well. For the civil work during the Tang Dynasty, there were two most difficult links. One is the quality of the workers, because those peasants who are sent everywhere to serve in forced labor come to work, and they have not been doing the work for a long time, and they often leave after ten or twenty days, and they are let go before they can be skilled workers in a distance. Even the time delayed in the middle is much more than the time of official service. This is very detrimental to agriculture.

Shi Bufan's cooperative model has made many farmers begin to move to the road of full-time civil engineering. At present, many civil construction workers are not only very skilled, but also can live up to the efficiency of a dozen or even dozens of workers in the past, and will not destroy agricultural production too much, so that the problem of workers has been solved.

As for the other difficulty, that is, in the collection of materials, there is another material that is the most difficult to collect, that is, large stones. Perhaps later generations thought that big rocks were nothing and that they were almost easy to get. However, it was not easy to collect large stones in the Tang Dynasty. Stones are very hard, and it is difficult for ordinary people to destroy them even by various means. If you want to destroy these big stones, you can only use artificial opening of a small hole, then put some fuel in it to burn, and then quickly cool it, and crack it through this principle of thermal expansion and contraction.

This method is not only time-consuming, but also very labor-intensive, so the price of many large stones remains high. The high price of such large stones will definitely affect many large-scale projects, and large stones are often things that cannot be lacking in large-scale projects. In particular, there was no corresponding bonding technology in ancient times, and the bonding technology in ancient times was too poor to bond small pieces of stone into large pieces of stone.

As for cement, cement cannot completely replace the role of large stones. Especially in some really special processes related to safety, it is not possible to use cement, and the hardness of cement and the hardness of some granite cannot be compared. The vast majority of cement, even after more than a thousand years, cannot be compared with real stones. Cement cannot completely replace large stones, and even in many dam sluices that are really related to safety, they must be molded in one piece, and large stones without any bonding processing must be used as sluice gates, which is absolutely unavoidable.

In particular, the ancient bonding technology is not up to par, and the dependence on large stones is even greater. Yan Liben, as an engineer for several generations, is very clear about this matter. Especially for the construction of the Grand Canal, many places relied heavily on large stone blocks. However, large pieces of stone are a difficult problem, even if there is no way to really solve it at present. There is no special means for this large stone to be mined in the mountains by water mills. This is determined by the physical properties of the stone itself, the hardness is too high, and it is difficult to shake it by manpower alone.

"Brother Yan, I think we can get something, once it suddenly explodes, then such a large stone will also fall. It is even possible to blow up the mountains at once, so that places where we could not build roads in the past do not have to take detours from the countryside. Even the bluestone slabs that we needed directly when we built the roads could be made directly from those mountains. As long as the large stone is taken down, only yo ah after some post-processing, then we can easily make it. ”

"Do you have a way to get a big piece of stone?" Yan Liben asked happily.

If you can get a large piece of stone, it will be of great benefit to the construction of various projects. The collection of stone is the most difficult, especially the pressure of various stone collections. Only when these stones are done well, the speed of various civil engineering construction can be further accelerated.

"It's very simple, just use gunpowder. As long as we can increase the power of gunpowder, then our large amount of stone can be exploded directly, and when the time comes, a large number of stones will fall down from the mountain, and we only need to properly screen it. Shi Bufan said.

"Gunpowder? The kind of blast rod? Will that kind of thing work? Yan Liben asked.

"Yes, I think the potential of gunpowder is far more than that, as long as we can test more concentrated formulas, streamline the formulas and make better proportions, then we can quickly test the corresponding most powerful formulas. When the time comes, it will not be difficult to blow up the mountain and blow up the rocks. Shi Bufan replied.

Gunpowder has a lot of uses in many ways, from military use to later blasting rocks, and many materials can be obtained. In terms of various mineral smelting, gunpowder can also be used to blast up many mines and directly collect the ore inside. For those ores buried in the mountains, they can also be blasted and mined. As for whether the smelting technology can pass the test, then this is another matter, and the ore will be mined first.

All mineral mining is to mine those that are easy to mine first, and when the technology of later generations is advanced, it can be used to mine those that are difficult to mine. This is the norm, and technological progress will turn ores that are not valuable to mine into valuable ores. This gunpowder is far from being only for military use, but also for civilian use.

"Shi Caochang, what do you mean?" Yan Liben said.

Shi Bufan replied: "It's very simple, in fact, I plan to cooperate with the Yan family to start a company specializing in contracting various large-scale civil engineering sieges for the imperial court and the people." I asked Miss Qin to fund and cooperate with you, and then your Yan family will come up with technology and work together to build various civil projects. ”

"Recently, isn't Young Craftsman Yan Lide preparing to propose to the imperial court to transform the functions of the general as a supervisor, from the direct construction of civil engineering and siege cities in the past, to a subcontracted department? In the future, all civil engineering projects in the Tang Dynasty will gradually be subcontracted to businessmen by the supervisors, so that not only will the imperial court save money and improve efficiency, but also ensure higher quality and avoid more corruption. ”

"And we might as well cooperate and form a company responsible for contracting the imperial court and various large-scale civil projects, so that we can make money together."

"Although we don't have a deep friendship with the court, the court belongs to the court, and business belongs to business. Although there was no friendship in the court, the patella would hinder communication in business. And the technology of the Yan family is famous for our entire Datang and is trustworthy. ”

"When the time comes, we will work together, not only to contract the civil engineering works of the imperial court, but also to use new gunpowder to open mountains and blow up stones, what do you think?"

Yan Liben felt quite interested, as an engineering family of several generations, of course he knew that if he did what to do according to the times, then there would be a lot of profits here. Shi Bufan proposed to make this gunpowder, coupled with the use of a new type of professional civil construction workers separated from agricultural production, then if this new type of gunpowder can be quarried in large quantities, then the profit of contracting various civil engineering projects is absolutely high.

The Yan family not only mastered the civil construction department of the imperial court, but also changed its functions from direct construction in the past to subcontracting to businessmen, so that the Yan family directly grasped the subcontracting power and could obtain a lot of siege construction business.

Coupled with the gunpowder blasting technology, mining large stones in this way is not only not difficult, but very easy. In this way, many sieges that ordinary people could not do, and their Yan family's company could also do it. Through the civil construction technology of the Yan family, the entire Datang will be trusted, and everyone can rest assured of the quality of the project.

The profits in this are enough to make Yan Liben red-eyed, even if he mainly develops in officialdom, but in politics, money is not omnipotent, but no money is absolutely impossible. The economic foundation determines the superstructure, and if officials do not have money, they will not be able to effectively fulfill their governing needs.

In fact, the meaning of the existence of the government is to protect property and interests, and the control of the government is to control production, and production is for economic interests, so in fact, the government also exists for economic interests.

"Okay, this business is good, but can you guarantee that you can research this kind of gunpowder that will open the mountain and blow up the rocks?" Yan Liben asked.

"Yes, it's not difficult!" Shi Bufan replied.

Shi Bufan already knew that this gunpowder was nothing more than one nitrate, two sulfur and three charcoal, as long as some blending was carried out according to the ratio of the three, it would definitely be possible for others to test it a few more times.

This gunpowder can not only be used for military purposes, but also for civilian use, and Shi Bufan intends to use it as a civilian means, which will also be of great help to the development of all walks of life in the future.

As for whether it will be taken away by the emperor and kept secret, this is actually just a matter of unfounded worry. Many people traveled to the Tang Dynasty and invented gunpowder, making it seem that Emperor Li Shimin was nervous, and he had to strictly control and keep it secret, afraid of flowing out and even all kinds of nervous behavior.

In fact, this is just a matter of worrying about the sky, even the Ming Dynasty, which held the most prosperous firearms in China, and the Ming Dynasty did not restrict gunpowder so strictly. Gunpowder is really just a consumable after all, and if you have consumables and don't use props, it's actually useless at all.

If you want to exert the true power of gunpowder, you still have to rely on bombs, artillery, guns and other weapons, if you only have gunpowder, it is difficult to really exert its true power. The Ming Dynasty restricted artillery firearms, not any gunpowder. Gunpowder is not very powerful in nature, and if you don't borrow firearms, cannons and various tools to exert its power, then gunpowder is actually not very powerful, and it can't really be used for military purposes.

Gunpowder is nothing more than a consumable, and it should be the tools that use it, not the consumable, that is restricted. Therefore, the Ming Dynasty restricted artillery to gunpowder, not gunpowder. Nervous restriction gunpowder, that is actually not the point.

Gunpowder doesn't need to be too tightly restricted, it only needs to be purchased after a certain amount of review, so you don't need to get nervous. As for saying that it is used for blasting, I am worried that some people with ulterior motives will use it to destroy, this is actually not much. In a peaceful and harmonious world, who would have brains to blast everywhere? As long as it is properly audited, this explosion can be avoided to the greatest extent.

In the stable environment of the current situation, in order to prevent the explosion of the possibility of the emergency, the nerves will also be nervous to lock up the gunpowder and not release it, which will delay the economic development on the other side, and how much the development of the country will be delayed! Therefore, it should be the firearms and artillery that use gunpowder, the tools of war, that should be restricted, not the gunpowder itself.

To limit the gunpowder itself, that is completely missing the point. Although the gunpowder restriction may be a little bit, it is definitely not as nervous as many Tang Dynasty travelers. The ancients were not completely stupid, and of course they knew that gunpowder would not be able to be used for the most military purposes without such tools as guns and cannons. Rather than to prevent the explosion in the event of an explosion, the economic development loss caused by the restriction of gunpowder over the years is definitely many times greater than the loss of the explosion in those eventual cases. So the ancients would not have been so stupid to impose large-scale restrictions, severe restrictions, for the sake of a threat that is not too big gunpowder.
