"By the way, Da Xia, why did you come here? And still haven't come to me? Geng Jingzhong asked strangely.

Xu Xingxia just smiled slightly, he couldn't say that he had gone to look for you, but he was stopped by the guards at the door and couldn't get in! So he spoke. "You're so busy, I don't dare bother you!"

Geng Jingzhong saw his expression, and he also knew a rough idea: "I understand, it must be the guard at the door who is blocking you!" Hey, don't complain, the main reason is that there are too many relatives from my hometown, and my father can't recuperate with peace of mind, so I ordered that no more visitors from my hometown should be allowed to enter. By the way, you haven't explained in detail how this diamond came from? ”

"I didn't care about it at first, but that time I went to Wafangdian to play with friends, and I happened to pass by a small hill that had collapsed. It was so bright that I was dazzled by one of the guises and almost didn't fall off my horse. So he ran to him and took it out, and found a lot of it around. I looked good, so I took it with me. In the beginning, I thought of it as crystal, but it was brighter and better looking than crystal, and then someone recognized it as a diamond. Earlier, I took this thing to the capital to find the second and third sons, and got acquainted with some princes and disciples in the capital, and no one in the capital liked these, and then I came to Fujian! ”

"Oh, I see!" Geng Jingzhong couldn't help nodding slowly, and then continued to say to Xu Xingxia with a smile on his face: "Da Xia, you have come thousands of miles to join me, but you haven't even seen my face. Now, brother, I'll give you a chance to make a fortune as compensation. ”

Xu Xingxia still wanted to speak. said he didn't think so. But Geng Jingzhong raised his hand and stopped him from speaking, but continued to himself: "You don't have to say it, listen to me." I know you're doing well now, so you can keep the shares of the road administration company here, but you need to go back to your hometown. It's not that I'm going to drive you away, it's that I need you to mine this thing for me! He said. Picking up a small diamond, she said to him.

"Brother Zhong also likes this diamond, no, yes, diamond?" Xu Xingxia was very puzzled, this thing was worth a few dollars, and it was just a novelty for him to take it out. In the past, he sold a little, and he only made a few hundred taels of silver. This box alone is worth thirty or fifty taels of silver. "Brother Zhong, this thing is not valuable. There should be quite a few of them in Wafangdian, if you want. I'll send someone back to help you dig some! I don't have to go back, I'm in a mess! ”

"Hahaha, you're wrong, I'm talking about big money, I'm talking about this diamond. This thing is not worth much on our side, but it is worth the old money when it is sent to Western countries! Just such a small piece can be exchanged for ten taels of gold, do you believe it or not? Geng Jingzhong laughed after listening to it, this is the difference between the aesthetic concepts of the East and the West, in China, there is no diamond in the definition of jewelry, the best is beautiful jade, including jadeite and nephrite, in short, jade, warm as water, representing a humble gentleman, this is a valuable thing. Then there are pearls, agate, red coral, and so on, but there is no diamond.

On the contrary, the West is different, and it recognizes this thing there, and gold is not as valuable as it. Of course, gold can be circulated directly as currency, while diamonds are not known to everyone. The most ordinary people will only recognize gold, and nothing else.

"This, this, such a small one is ten taels of gold?" Xu Xingxia's surprised eyes protruded, he had previously disposed of four or five hundred at such a low price, that was not a loss of four thousand taels of gold, that was more than forty thousand taels of silver! Oh my God, I'm the biggest fool in the world!

"Yes, but this thing is not worth much in our country, and almost no one wants it. It just so happens that in a month and a half, one of my caravans will be heading to the Tessie Kingdoms, and when the time comes, I will bring some of this thing with me, and I hope it will be of great use! I haven't been back to my hometown for more than ten years, you are familiar with the place, just hurry up and go back, help me mine some, I can be useful. When the time comes, how about you get 30% of the profits? Geng Jingzhong also didn't want to treat his own hair small, Sancheng was already a lot of profits, after all, he had to spend energy to send this thing to the West.

Xu Xingxia has been in business for seven or eight years now, of course, he knows that the profit of thirty percent is already very high, not to mention that he goes back to mining, almost no cost, and digging it out is money. However, he has no sales channels at all, and he relies on the fleet of the royal palace, and he is already overjoyed to be able to share 30% of the harvest! "Brother Xie Zhong, I'll pack up my things and go back to my hometown immediately, recruit more people to start work, and it only takes half a month to find a thousand pieces!"

Geng Jingzhong looked at the diamond in his hand, if it is a thousand pieces, it should be a lot, if this is used as a unit, there are thousands of carats! Could it be that diamonds in this era are so abundant and so easy to mine? Geng Jingzhong really couldn't figure it out. In fact, it is not too surprising that Wafangdian, as the location of China's largest diamond mine, contains a lot of total amount, and no one has ever mined this thing before, so Xu Xingxia took the lead in digging the most superficial and easiest to mine.

Geng Jingzhong was disturbed by this matter, and he didn't have the heart to check the distance below. I don't dare to make any trouble in the process of road construction, after all, their own intelligence agencies are not dry food, and even after the road is repaired, they still have to accept random inspections by their people. In case it is found to be unqualified, then the person responsible for repairing the road will be unlucky!

Drive straight all the way, no longer stop, and go straight to the starting point town. It's been a long time since I've been to the starting point, and it's still so bustling. In the end, there are still too many mountains in Fujian, and it is impossible to build a straight road from Longyan to Fuzhou. It was the second time he had come this way, at least the first half of the journey was the same, this time the road went around a little, passed through Quanzhou, and then connected to Zhangzhou Mansion, and finally converged on the road east of the starting point town.

The further you go in, the less damage you have suffered some time ago, just by looking at the bias of the trees. Most of the trees in Fuzhou, Quanzhou, and Zhangzhou are slanted, and it is fortunate that the typhoon did not knock down all the trees. It's normal for trees to be crooked. The further in. The smaller the angle, the more inclined this angle is. Two months have passed since the disaster, and production has already resumed in various places, and the road is full of pedestrians and vehicles. The convoys came and went one after another, the small ones were a single car, and the large ones were nearly 100 large cars that stretched for hundreds of meters. The team planted a flag to represent their respective business names, and also made a publicity by the way.

Watching the carriages move forward in turn like ants, Geng Jingzhong began to frown again. Now the speed of development is already very good. But I still don't feel satisfied. What is the flaw?

Railway, by the way, railroad! If there is a railway, it will be even better. Now all caravans rely on horse-drawn carts to transport goods, but the cost of raising horses is very high. In addition to the horses, there are also a lot of people needed along the way, and this person eats horses and chews a lot of silver a day.

However, if there is a train. That's a different story. There is no doubt about the capacity of the train. The volume of traffic transported by a train. It is equivalent to the transportation volume of thousands or even tens of thousands of horse-drawn carriages. As long as you run lightly, you can transport a large amount of goods. In later generations, if there was no railway, then that area would be absolutely poor and backward, and the railway was also called the lifeline and wealth line. The development of every city is the development of its railway transportation.

One of the most vivid sayings heard by later generations is that wherever the railroad goes, the sphere of influence expands. From a military strategic point of view, the role of a railway line cannot be overstated. The rapid and massive transportation capacity and strong radiation capacity all make the railway line an important means of future expansion of the Mawei Army. It must be known that when the war began in the future, the biggest trouble faced by the Mawei Army was logistics and transportation. The use of mules and horses for transportation, outdated. Besides, Fujian is very short of horses, or Fujian is not a place to produce horses at all, and there is no place to buy them. Therefore, if there is a railway to transport it, then he can now raise his army.

As long as he thought about it a little, Geng Jingzhong felt extremely excited! The Mawei Army fought in front, and the railroad stretched all the way forward in the rear. Trains were loaded with soldiers and supplies. No matter how stubborn the opponent is, in front of such a steel monster, there is only a share of surrender. Of course, it is okay not to surrender, and the artillery and muskets of the Mawei Army will tell them what the truth is.

For Geng Jingzhong, if the railway can be repaired, the railway lines will be like ropes, which can tie up the enemy and make them unable to move at all. But Geng Jingzhong also knows that now this is just a matter of thinking, and the highway has not been repaired before it has begun to think about the railway, which is a bit of a fool's dream. But if you don't want to think about it, then you will never make progress.

There is no need to think about whether it can be done, at this stage, airplanes, cars, ships, etc., it must be difficult, the technology has not yet developed, and the gap is too far. However, trains are not impossible. Now there is a rudimentary steam engine in the West, although I have sent people to Europe twice and have not found this talent, but it does not mean that I will not be able to recruit this next time.

Although the history of Stephenson, it was in the early nineteenth century that the first train was developed. Subsequently, the world's railway construction entered an era of rapid development. But now that he has a time-traveler with advanced vision, he can use his own strength to accelerate the development of technology in this area. To be honest, the early steam locomotives didn't have much technical content. As long as the horsepower of the steam engine is large enough, it can be used as a locomotive.

As for laying railroad tracks or something, it's even simpler. With Fujian's current steelmaking and ironmaking technology, it can fully meet the needs. There is no problem with cement, and now there are cement kilns everywhere in Fujian, and after the road is built, there is no problem at all to provide for the construction of railways. It seems that the amount of cement needed to build a railway is not as much as that needed to build a road.

Of course, Geng Jingzhong did not understand the specific technical details. Perhaps, in some aspects that he didn't know, there would be a little difficulty. However, he has enough reason to believe that as long as the locomotive is done, other technical details will not be a problem. It was so challenging to get the train to appear 150 years earlier, and it seemed that the project had to start working now.

"It seems to be getting more and more prosperous here!" Geng Jingzhong looked at the busy starting point town and said with emotion.

"Yes, Shizi, you built this place!" Yang Jian also sighed slightly. But it was a sycophant. "That's right. Shizi. Where do we go first? Do you want to go to town or check out a few workshops first? In fact, he himself really wanted to go to the artillery workshop first, in addition to the workshop on the Mawei side, the workshop here in the starting point town is larger, and half of the cannon casting masters here are Westerners, and half are old Han craftsmen invited from all over the world.

Now the artillery workshop and the musket workshop are more and more detailed, research and development of fire. Medicines are specially developed for fire. Medicine, those who cast artillery are specialized in casting artillery, and those who make muskets are also in charge of muskets. The categories are clearly divided. In the workshop, anyone who makes a little progress is rewarded heavily, and for this reason, the passion of these developers is greatly stimulated, and they rack their brains to improve the existing products. Here, in addition to the temptation of heavy rewards, there is also the temptation of official positions, which may not be very tempting for Westerners, but for other Han craftsmen. That's bigger than the temptation of money.

The workshop here, especially the fire. Pharmacy workshop. I have long received some theoretical research methods in chemistry written by Geng Jingzhong. Geng Jingzhong also tried his best to write in an easy-to-understand manner, but that's it, there are still a lot of old craftsmen who don't understand, but those Western craftsmen who have been invited back with a lot of money are much better. It's not that Geng Jingzhong is dissatisfied with his craftsmen, the main difference between the two is that China has always despised artisans since ancient times, and the vast majority of artisans are illiterate and don't understand much, so they basically don't understand what Geng Jingzhong writes.

These master craftsmen invited back from the West are much better, they basically know a lot of knowledge, and Western learning is what they have been exposed to since childhood, after getting the information written by Geng Jingzhong, they took a cursory look at it, and they basically determined that this is feasible. Then they were shocked one by one, and they all revered Geng Jingzhong as their gods. Geng Jingzhong's chemistry major in the past four years is not for nothing, although after graduation, he transferred to the teacher qualification certificate and became a teacher, and forgot a lot of professional knowledge learned in school, but some basic ones are still remembered.

However, it has been two years since these Western masters were invited back, and it has been more than half a year since the newcomers arrived, so why is this thing still unsuccessful? Geng Jingzhong is also a little depressed, this Fujian is now building roads and digging rocks, which requires a lot of fire. Medicine, if you can get the stable dìng you want sooner. Anyway, it will be worry-free, and your own muskets and artillery will also be greatly powerful.

The research results of Mr. Nobel's life, summarized in the book are only a few pages of content, and Geng Jingzhong has moved them all out at once and used them in advance, and there will be no more Nobel prizes in the future, and I don't know if after 150 or 60 years, the Nobel Prize at that time will not be popular. Yao Lei. What kind of person will you become?

For the Nobel Prize, Geng Jingzhong is very respectful, the Nobel Prize is the dream of every scientific researcher, it is recognized as the highest achievement in the scientific community, but it is a pity that China has not won a Nobel Prize in science, until Geng Jingzhong crossed the time has not, what a pity!

For Ray. Regard, Geng Jingzhong is looking forward to it, he used to send a letter every few days to ask about the progress, but then there was no result, Geng Jingzhong didn't ask, when the research came out, it was arbitrary, as long as it could be researched, it was Geng Jingzhong's last expectation. But now it's been two years in a row, and there is no news at all, and I really want to go and see it again.

Speaking of history Ray. The invention of the tube is really full of twists and turns, and Mr. Nobel has paid too much for it, so his name can go down in history.

At the beginning, in 1847, the Italian chemist Sobrero reported his research results and said that glycerin was treated with nitric acid and sulfuric acid to obtain a yellow, oily, transparent liquid, that is, nitrate. Change. Sweet. oil, "this liquid can burst by vibration. Fried, what can be used in the future, only the real yàn in the future can tell us. ”

Mr. Nobel's teacher, Professor Xinin, did hammering in St. Petersburg. Change. Sweet. The oil exploded. Fried the real yàn to Nobel and said that if you can come up with a practical way to make it explode. bomb, it will be of great military usefulness. This aroused the great interest of the young Nobel. Since then, Nobel has never forgotten this and is even more determined to complete this invention.

After a long period of thinking and practice, Nobel realized that it is necessary to make nitrate. Change. Sweet. Oil blast. To fry, it must be heated to burst. The explosion point is between 170 and 180 degrees, or gravity impact, and the search for a safe detonating device is the subject that Nobel has set for himself. In 1862, with a loud noise, the ditch splashed and the ground shook, and Mr. Nobel discovered the detonation of nitrate for the first time. Change. Sweet. The principle of oil. Use a small amount of general fire. Medicine. Change. Sweet. The oil exploded violently. Bombing is the "detonator" invented by Nobel. For this reason, two years later he obtained nitrate for the first time in Sweden. Change. Sweet. Oil detonating device - Ray. Tube of patents, completed his first heavy dà invention. So far, Nobel has made nitrate for the first time. Change. Sweet. The oil becomes a frying that can be used in industry. Medicine.

At that time, nitrate was produced in large quantities. Change. Sweet. Oil is fraught with risks. Nobel set out to improve the production process and strive to achieve safe production. It's too dangerous to study this thing, and it's exploded many times. Many people died in the bombing accident, including Nobel's youngest brother, Lu Dewei, whose father was also seriously injured. Yet Nobel still forged ahead and never flinched. He invented the use of cold water pipes to dissipate heat to produce nitrate. Change. Sweet. The cooling method of oil, and the corresponding machine qì was designed, which initially removed the obstacles to mass production.

The new "frying oil" can save a lot of manpower in blasting engineering, and it will soon be widely used. In addition, in order to promote his invention, Nobel personally went to various places to carry out the practice, so that his reputation spread far and wide, and more and more places asked for supplies. But because at that time people were interested in fried. The danger of medicine is very ignorant, and in long-distance transportation, strict liquid nitrate has occurred in various places. Change. Sweet. Oil blast. Bombing accidents, letters to the police poured to Nobel.

A few years later, he used porous diatomaceous earth with nitrate. Change. Sweet. The oil is mixed to make two solid fries. Medicine, this safe high explosive. The drug soon obtained patents in Britain, France and Germany, and was used in mining, road construction, tunnel excavation and other construction. But this kind of fried. The explosion of the drug. The explosive power is just nitrate. Change. Sweet. Three-quarters of the oil. Diatomaceous earth exploded. After the advent of the drug, it exploded. The barriers to the application of medicine in industry have been removed. Almost at the same time, Nobel also saw its shortcomings, that is, not only exploded. The explosive power is not as good as nitrate. Change. Sweet. oil, and it is violently fried. When the medicine is damp or pressurized, nitrate. Change. Sweet. There is still a danger that the oil will come out of the way.

So Nobel began to experiment with the development of a method that also had nitrate. Change. Sweet. Explosion of oil. Explosive power, and fierce explosion. A new variety of drug safety performance. The hard work paid off, and after countless failures, in 1875, the solid cavity was fried. Medicinal and soft plasticity excellent gelatinous frying. Medicines came out one after another. It's bursting. The frying effect is high, and the price is relatively cheap. It is more pure than nitrate. Change. Sweet. The oil has a bigger burst. explosive power, but also has greater stability, ignition will not explode. Fried, soaked in water will not get damp. Gelatinous fried. The medicine was soon widely used in blasting projects in Switzerland, France, and Italy.

When Geng Jingzhong was studying, he paid a lot of attention to the content of this section, and remembered the theoretical knowledge very firmly. But knowing that theoretical knowledge and practical production are two different things, there is still a big gap between the science and technology of this era and two hundred years later, at that time, Nobel could not stop the accident, and now let Geng Jingzhong get it, he does not dare. The craftsmen did not understand these theories, so they delayed at first. Until I invited a Western master, some basic Western fire. If the pharmacist can understand it, he can start to develop it with the existing conditions.

As for whether there is any danger in the real yàn, it is definitely there, so do these experts dare to develop it? A large amount of money is put in front of them, and the possible danger is no longer a danger! It's been two years, and I think it's time to have results here, and with so much money invested in it, it's impossible not to have a little effect.

"Let's go to a few workshops first. You kid is anxious about your Marine Division's artillery, I said a long time ago, don't rush, the workshop has its own rules and regulations, and after ensuring the artillery of the new naval fleet, your part will definitely be fine. (To be continued......)
