After becoming proficient, Warlock Cao Fengxing could make nitroglycerin much faster than Cheng Jinzhou himself.

In particular, his hands are very steady and his operation is flawless, which makes people feel reassured. The most famous thing about nitroglycerin is not its huge explosive power. The thing that has the deepest impact on people is always the tipping point super. It explodes when heated, pressurized, or even shaken. At that time, Europe even completely stopped the production of nitroglycerin in order to reduce accidents. Americans wanted money at the expense of their lives, so naturally they had to be a different matter.

When I was in the laboratory, there was another interesting way to play with nitroglycerine. Put a drop of it on the flat ground, and then hit it hard with a larger long-handled hammer, and it would make an explosion equivalent to the size of two kicks. If If the risk is not considered, it is much cheaper to use nitroglycerin as firecrackers. Nitroglycerine produced in the laboratory only costs thirty or forty cents per gram, and one drop does not even cost one-fifth of a gram. If the factory uses the Schmid method, the Byaz method, etc., the cost can be reduced to An outrageous level.

To test the effects of nitroglycerin, a weight hammer is also a good choice.

Cheng Jinzhou did not avoid the two star warlocks. He put down as little as possible in the open space in the middle of the yard. Then he turned around, picked up a bench and handed it to Lu Xu, saying, If you drop the liquid, be careful, it will explode.

How violent? Lu Xu asked seriously. There was no guarantee that the things made by the star warlocks would be very powerful. There were also things he didn't pay attention to during the whole process.

I guess there will be some wind. Cheng Jinzhou shrugged. The principle of explosives is actually to expand instantly and then generate huge pressure, thereby destroying buildings and impacting the human body. Theoretically, nitroglycerin will expand about 10,000 times, but if it is less than 1g, it will not cause harm to the human body.

Lu Xu snorted, picked up the bench and smashed it down.

Boom sound.

The crisp sound made by the stone stool was completely covered up, and the sound was as low as No in a nightclub.

Cao Feng shrank his shoulders suddenly, turned around and looked at the basin of nitroglycerin he made, and hesitated: This is a murder weapon.

There is no industrial sulfuric acid production. If others use this thing, it is really better to kill with a sword. Cheng Jinzhou said indifferently, and then added: There are many other uses for this thing. I will explain it to you later.

As he spoke, Cheng Jinzhou took out a small bottle of nitroglycerin, leaving the rest in the basin and said, Is there any way you two can transport this thing without shaking at all?

Just wrap it up with the star array. Lu Xu said and started to move his hands.

Cheng Jinzhou was frightened. Fortunately, Lu Xu also saw the power and did not act recklessly. He first put the nitroglycerin into the jar that originally contained sulfuric acid, and then moved the star array to make it tightly sealed. There was no problem at all.

Cao Feng, who was a researcher at heart, first asked: Have you written a results report? I'm afraid many people would be interested in this kind of thing. But it's also a bit dangerous.

Let's talk about it later. Cheng Jinzhou shook his head indifferently. The emergence of explosives is not so much the result of a certain gentleman's madness as it is the necessity of industrial development. During the experiment, chemists will obviously constantly test various properties of new and old products, just like junior high school students pouring all the reagents on the table together to see what happens.

Nitrogen explosives such as nitroglycerin were born from the extremely large supply of concentrated nitric acid and concentrated sulfuric acid. By the 19th century, the manufacturing cost of the two dropped significantly, and research became more and more thorough, and chemists seemed to A cornucopia was found - this was an era when explosive scientists were rejoicing. As long as concentrated nitric acid and concentrated sulfuric acid were mixed together, and then an organic matter was added, an explosive could be created.

The reaction between fuming nitric acid and dimethylaniline resulted in tetryl, which was used by the German Krupp Gun Factory in 1906 to make artillery shells. Pentaerythritol and concentrated nitric acid give Taian. In the early days of World War II, Taian was the main raw material for making bombs and artillery shells. RDX is also a nitrate explosive. Its full name is trimethylenetrinitramine. It is made of concentrated nitric acid and rotopine and has been used until the 21st century. Because it is more suitable for mixing other explosives, RDX is used every day. Mixed together by different laboratories, it supports a large number of researchers. The ones that have been used until the 21st century are Oktokin, anti-tank armor-piercing shells after World War II, the former Soviet Union's Katyusha, and many missiles like to use it as a charge. The principle is the same simple.

Just like the computer scientists in the early Internet era, achieving this kind of thing often requires some luck. When fortune comes, third-rate scholars complete first-rate research; under fortune, first-rate scholars do third-rate trivial work.

No matter it was the Great Xia Dynasty or the so-called Far West Zone, no country could enter the era of large-scale industrial production. Cheng Jinzhou was not worried at all because he had produced nitroglycerin. The Star Warlocks themselves were more powerful in combat. Much more. As for worrying about the country's efforts to develop and manufacture large amounts of sulfuric acid and concentrated nitric acid for this purpose, that should be a matter of luck.

Technology always saves more people than it kills.

A similar understanding is that if any country enters the era of industrial mass production, the invention of nitroglycerine will only be a matter of time - if a gentleman prepares nitroglycerin for the first time, the total amount should not be too large, and there is no thought of it. Chance was killed on the spot.

Cao Feng was always concerned about mathematics and physics, but he said with great interest: Mr. Cheng is also interested in alchemy? I suggest publishing an article, and you can also exchange contribution points from the association.

Initial contribution points?

of course not.

Cheng Jinzhou showed a lack of interest. Since he didn't need money now, his desire for contribution points immediately dropped to a lower level.

Cao Feng's work is related to chemical physics. According to the view of this era, it can be regarded as a kind of marginal alchemy. He persevered in going out with Cheng Jinzhou, naturally so that he could spend more time together and get more help in mathematics. It is naturally the best way to draw Cheng Jinzhou's interest directly into his own field.

Seeing that Cheng Jinzhou had finished what he was doing, he asked again: I wonder if the method you are using now can be used in lenses?

Wind, horse and cow are irrelevant. Cheng Jinzhou patted his forehead, shook his head lazily and said, Let's put this thing somewhere first, and then we can chat slowly.

That's fine. Cao Feng said and jumped into the air.

Cheng Jinzhou was held in Lu Xuti's hands again, and he was frightened and transported by the flying creature together with the nitroglycerine box.

…

Louqingfang is located in the southeast corner of the Second City. It is an interesting place that everyone in the capital knows well.

Logically speaking, the place for fireworks should not be within the second gate, so in the planning, Louqingfang was placed on the other side of a Qinghe River.

The smart gentlemen started a vigorous bridge-building activity decades ago. Coupled with the comings and goings of various boats, and volunteers paving roads for free, the area was completely developed and connected to the two cities.

Starting from the continuous hotels and restaurants a mile away, the place that is not Lou Qingfang has become Lou Qingfang. When you go deeper, there is even more music and singing, and you can see a leisurely atmosphere.

A street of shops, a street of singing and dancing, a street of eating, drinking and entertainment, plus a street of gambling houses and brothels, the entire Louqingfang has formed a standard entertainment city. Even if it comes from later generations, watching The street market was still very lively in the afternoon, and Cheng Jinzhou had to admit that any era has business geniuses suitable for it - the gentlemen on Wall Street are 30 years ahead of China's local businessmen, but if they want to make ups and downs in the Chinese market, they must at least It will take another 30 years. Every city and era has its own specialness and pride, and it cannot be done just by talking.

Cao Feng was familiar with the capital and found Zhao Quanfu's favorite art museum. Before Cheng Jinzhou could say anything, Lu Xu wanted to throw the jar out.

Cheng Jinzhou quickly stopped him and said, You can't just throw it in?

Lu Xu wiped his forehead excitedly and said nonchalantly: Who doesn't know that you want to blow up Zhao Quanhui? Seeing that you have made something interesting, I will do you another favor.

Star warlocks who had been on the battlefield didn't care about blood at all, or Lu Xu himself didn't care.

It's better that you just use the star formation. Cheng Jinzhou was helplessly carried by Lu Xu, and he said to a bridge below: Let's go there, and I will teach you to do things that an ordinary star warlock can't do.

What is it?

Detonate from a distance.

Viewed from the air, the stone bridge in front of the Jueyi Museum is the only way to pass. The bridge is about three meters higher than the ground, with a span of more than ten meters. The river below is probably freezing cold at this time. Of course, Cheng Jinzhou did not think that Mr. Zhao Quanhua would still have a chance to enjoy the cold river water for a while.

About seven or eight kilograms of nitroglycerin, if placed carefully indoors, will have no problem destroying a township government office building - if it exceeds the standard, it will be discounted, and if it exceeds the standard and cuts corners, it will be discounted - but in an open place, bombs The power will always be weakened a lot. Throwing it into the building is actually the most scientific choice, but it is the least willing choice.

Cheng Jinzhou stuffed the box into the bridge arch without being picky, and said to Lu Xu: I will detonate it later, and you can help heat this thing up. It doesn't count as violating Warlock Liu Kuangxing's order.

What does it have to do with him? Lu Xu felt a little embarrassed in front of Cao Feng and became careless again.

Cheng Jinzhou smiled and said to Cao Feng, Let's find a restaurant nearby where we can see the stone bridge.

Cao Feng could understand Cheng Jinzhou's thoughts, but compared with the grandson of a court prince, he cared more about mathematical research. Ordinary Star Warlocks sometimes actually live more comfortably. If it were Star Warlock Liu Kuang, he might have to think carefully about it.
