"Ouch, Li Hui, you little rabbit cub, don't explain it in advance, my eyes won't be blind, right?" , Qiu Baoren's personality is relatively rough, and he has never been as polite to Li Hui as others, and after his eyes were spent, he was the first to scold him.

"Don't worry, rest assured, it's a seventy-five-millimeter sampan gun, and it won't blind your dog's eyes", Li Hui laughed gloating at this time, allowing the Beiyang generals to see another side of him for the first time

By the time everyone recovered from the temporary blindness, the target had almost completely cooled, but the large hole in the iron plate and the black bumps on the ground that condensed the molten iron still fully illustrated the huge explosive power of the cannonball and the terrible heat it generated

Liu Buyun, the head of the Dingyuan pipe, rubbed his eyes that were still crying, and said everyone's thoughts to Li Hui with a strange expression, "This, Dongyang, you said before that we have no chance of winning just to make us wake up, with such a powerful cannonball, how can we not win?" ”

Li Hui shook his head when he heard this, and reminded the Beiyang generals not to be careless, "Saying that there is no chance of winning naturally refers to the situation before I came, if this new explosive can be mass-produced, when the shells and fuses arrive, we can indeed fight with the Japanese Navy." But don't be blindly optimistic, after all, we are really losing in terms of the rate of fire of artillery."

"There is another problem, although this silver explosive is powerful, it is a three-base explosive after all, the same as black powder. As we all know, even if black powder is granulated, it will still have the phenomenon of component separation after a long time, which will affect the power. Mixed explosives have this problem, the more components the more serious, so the shelf life of this new type of explosives will not be too long", Li Hui said this, suddenly remembered something, his face showed surprise, and he didn't even have time to say hello, so he immediately hurriedly left the test site and went to the dock, planning to rush back to Tianjin overnight to verify his idea as soon as possible

Seeing this scene, even Lin Taizeng, who has always been an introverted leader of the Zhenyuan number, couldn't help but joke, his tone was full of joy and expectation, "This kid may have a new ghost idea, sometimes I really want to cut his head open to see if there are two brains in it."

As early as when asked about the price of KClO3, Li Hui had the idea of using sodium chlorate instead, because the latter is cheaper, and because the atomic weight of sodium is smaller than that of potassium, the density of sodium chlorate is also greater, and the power of explosives should be further increased after replacing KClO3 with sodium chlorate.

However, sodium chlorate has a weakness that is difficult to overcome, that is, it is very hygroscopic, and it is easy to deliquescent when placed in the air

But just now Li Hui realized that even with KClO3, silver explosives cannot have a long shelf life, in this case, the problem of sodium chlorate being easy to deliquescent may not be as serious as Li Hui originally thought, after all, the sealing of artillery shells is still relatively strong, and Vaseline can be waterproofed.

In addition, thanks to the strict requirements of the inorganic chemistry teacher in the university, Li Hui knows that several sodium salts with strong hygroscopicity can be stored in the reagent bottle for a long time as long as a small amount of sodium chloride contained in them is removed, so as long as it is purified a few more times, the defect that sodium chlorate is easy to deliquescent may not be so fatal. Admittedly, doing so will definitely add to the cost, but it's at least worth experimenting.

After starting the actual production, Li Hui was soon pleasantly surprised to find that the two advantages of sodium chlorate could have a greater impact than he originally thought, because sodium chlorate has a higher oxygen content and greater density, so the proportion of petroleum jelly in explosives will inevitably increase, especially the proportion of its volume, and in this way, even if more aluminum powder is added, there is no need to worry about difficulty in mixing evenly.

And there is more aluminum powder, this power is naturally further enhanced, and aluminum powder is the densest of the three components, and the density of the new version of silver explosives has also increased.

In the end, Li Hui determined the composition of the new version of silver explosives to be sodium chlorate 61% / petroleum jelly 8% / aluminum powder 31%, its explosive power is slightly stronger than the same weight of picric acid, and its density is also larger, which means that the explosive power of the same specification of cannonballs after replacing the new version of silver explosives will be much more than when using TNT, which immediately makes Li Hui happy.

However, if this new type of explosive wants to be really put into practical use, it depends on how much impact the defect of sodium chlorate is easy to deliquescent, so Li Hui threw a shell containing a new version of silver explosive directly into the water, and planned to wait for ten days before taking it out for testing, if by that time, the explosive inside can still be used, then the shelf life of this explosive is enough for wartime, as for peacetime, as long as training and production are well coordinated, there is no need to worry about waste.

After the new formula of the silver explosives was determined, Li Hui also trial-produced sodium chlorate petroleum jelly without aluminum powder, although the explosive power of this shrunken version was only less than two-thirds of the same weight of picric acid, but it was enough for army weapons that mainly relied on fragments to kill and injure enemy personnel, and its cost was much cheaper than that of silver explosives.

That night, Li Hui couldn't sleep because he was too excited, so he wanted to see how many products the system could produce now, and he made an unexpected discovery, "Huh." Why is there an extra item in the explosives column? Sodium chlorate petrolatum explosives? What's going on? Is it possible for the system to produce explosives as long as they appear in reality? No, there are no formulas for the two silver explosives, and the TNT that has been discovered long ago, and even the picric acid explosives are not right, and some specific system technology should be needed, but why is the KClO3 petroleum jelly explosive, which was invented not long ago, not in the menu? Sodium chlorate petrolatum that has not been tested is available, and KClO3 should not be without! ”

Li Hui, who was puzzled, looked at the menu of system products from top to bottom, and found that many early products in his memory had disappeared, and he immediately understood, "Could it be that as long as there are better alternatives, those outdated products will not appear in the product list?" This is a good setting, otherwise it would be a waste of time to find hundreds of products in each column on this menu in the future."
