What's wrong with mines? Many people think that a sea mine is a very simple weapon. You just make an iron shell and fill it with explosives, then fix the trigger device, and finally throw it into the sea and you're done.

Compared with other projects in naval battles, this is so simple that anyone can do it to put it bluntly.

However, not everyone can use mines well. For example, the simplest iron case, the countries that can’t handle this thing will catch a lot of them, not to mention the suitable trigger device at the back. Terrible, there are even more countries that cannot be created.

Even if you can make qualified sea mines, you may not be able to use them well. The simplest laying is not just throwing mines into the sea. It involves a series of factors such as tides and water depth. If any of them are not taken into account, the mines you have worked so hard to lay may be in vain.

Li Xiao is undoubtedly lucky. If he had been born half a century earlier, mines would probably be impossible to deal with. The reason is that there is no suitable trigger device. Thunder mercury was only discovered in the early 19th century, and without this trigger device, it really cannot be done. . You can't get a long fuse to light a fire at sea (laughs).

Of course, even with a trigger device, the performance of the mine is still restricted by the explosives. In this era, the typical explosive is still black powder, and the explosive power of black powder is really average. Fortunately, sea mines are generally relatively large, so it doesn't matter if you have tens or hundreds of kilograms of explosives.

It's just that the efficiency is too low, and the damage effect is too poor. But for Li Xiao, this is unacceptable, because he wants the power of the mines to be strong enough. After all, the mines needed for laying mines are at least tens of thousands. If each mine needs hundreds of kilograms of black powder, that amount It's really scary, but if it can be replaced with other more powerful explosives, it will naturally be more economical and perfect.

It's just that explosives with greater explosive power are not so easy to get. The Nobel family died a few lives before they came up with nitroglycerin, and the power and safety of this thing are really only mediocre, at least Can't meet Li Xiao's needs.

Fortunately, Li Xiao had a long-term plan for this issue. Since 1849, Wallachia has cooperated with the Russian Academy of Sciences to invest in the development of new safe explosives.

Of course, this new type and safety need to be quoted, because the research direction given by Li Xiao focuses on picric acid and dynamite. The latter is familiar to everyone, the well-known explosive with two Ts. As for the former, most people are unfamiliar with it.

Picric acid was discovered very early in 1771, but it was only used as a yellow dye at first. Later, an accidental explosion made the French realize its power, so they switched to explosives.

However, there is one thing to say, that the power of picric acid is ideal, and it can even release toxic smoke when it explodes and burns violently. But this thing is an acidic substance, which can easily react with metals to form extremely sensitive picrates.

This kind of picrate has a very high mechanical sensitivity, and it can almost be said that it will explode when touched. If you think about it, the most critical performance of an explosive is safety. If it cannot be produced, stored and transported safely, then it is meaningless no matter how powerful it is.

It is a pity that picric acid is such an overly sensitive explosive that it is not completely qualified to be used in the military field. Therefore, although Li Xiao gave such a research direction, he also suggested researching yellow explosives at the same time.

Compared with picric acid, yellow explosive is much safer, otherwise it would not be called Laoniu explosive by later generations. Of course, the key point is that the raw materials of dynamite are cheap, and if there are sufficient oil resources, it will be relatively cheap to manufacture.

It is a pity that although Russia is rich in oil resources, later generations have been ridiculed as a gas station pretending to be a superpower, but at present, Russia's oil resources are relatively extensive in terms of mining and smelting, and cannot produce enough toluene. The difficulty of Dynamite is a bit higher.

Therefore, Li Xiao still suggested that the focus of research and development should be on picric acid. After all, the mechanical sensitivity of this thing is high enough, and if it is placed in an iron shell mine, it might blow up without a detonator. For this detonator, the fuze is relatively effective Low times can be considered as a supplement.

Of course, the arson effect of picric acid is enough for Li Xiao to value it more. After all, in the pre-ironclad ship era, most ships and even warships were made of wood, at most covered with a layer of copper skin. As far as explosives can be melted, it is simply a magic weapon, okay?

"Picric acid?" Kornilov frowned and asked, "Can this stuff really be used as explosives?"

Yes, as naval elites Kornicalov and Nasimov both received the best education, modern scientific knowledge is still not lacking, he knows what picric acid is, but he has never heard that this dye can be used as an explosive handle.

Li Xiao explained: "Yes, the effect is still very good, but it is a bit too sensitive. If used as explosives, the power is probably more than a hundred times that of the best black powder!"

The figure of one hundred times really stunned Kornilov and Nasimov, because this figure is really unimaginable, because they think that black powder is very powerful, and explosives that are one hundred times more powerful than black powder, this Does it really exist?

"The Academy of Sciences has done a comparative experiment, and this number is well-founded," Li Xiao patiently explained, "The only problem is that picric acid is very troublesome to store and transport, and it's too easy to explode!"

Neither Kornilov nor Nasimov took this to heart. After all, they are not experts in chemistry, and they are not at all sensitive to the mechanical sensitivity of explosives. If the one hundred times more powerful than black powder is true, then it has enough value.

"Then what are you waiting for!" they said impatiently, "immediately try to produce a batch of mines filled with picric acid, let us see the power!"

In fact, they didn't need to say that Li Xiao was ready, the urgently prepared hundreds of kilograms of picric acid had already arrived in Sevastopol, waiting for their consent to experiment.

Kornilov waved his hand and said, "No problem, I will prepare a target ship right away! But if the effect is not good, you will have to pay for it!"

"The effect will definitely satisfy you," Li Xiao said confidently, "The question now is, if you are satisfied, how can we produce picric acid on a large scale? After all, tens of thousands of mines are needed to block the Black Sea. Large quantities of explosives are required, and considering that war may be imminent, we must start production ahead of schedule!"
