"Ahem, ahem, ahem!" Wang Rucheng pinched his nose and coughed constantly, he hurriedly followed Yang Wenli and walked away to a ventilated place before he spoke: "Great Commander, this smell is so bad!" ”

"This is the smell of sulfuric acid, which is more pungent, and when it no longer bubbles, the smell is not so strong, and we also get the concentrated sulfuric acid we want." Yang Wenli said to him again.

Due to the small amount, it was only used for experiments, and it didn't take long for the glass containing sulfuric acid to stop bubbling, Yang Wenli dared to move the alcohol lamp tightly, and said to Wang Rucheng: "Rucheng, this concentrated sulfuric acid is highly corrosive, don't splash it on the skin, otherwise it will corrode the skin, and it will always corrode and go straight to the bones." ”

"Commander, since we have made sulfuric acid, what are we going to do next?" Wang Rucheng asked curiously. He is now like a thirsty elementary school student, hungry for the magic of chemistry.

"Don't worry, the temperature of these concentrated sulfuric acid is still too high, and when it cools down, we have to add potassium nitrate to it, use a glass rod, and stir it gently, and we get the concentrated nitric acid we want, and potassium sulfate solids that are insoluble in nitric acid."

Because it is winter, and there is not much sulfuric acid, between his words, you can see that the sulfuric acid is gradually cooling down, the main feature is that there is no longer a thick fog, Yang Wenli felt the temperature outside the glass with his hand, and felt that it was almost, so he added potassium nitrate to the cup, and used a glass rod, stirred gently, and cooled it slightly.

I used another clean glass and poured the solution in the cup, and sure enough, some crystalline solids were left at the bottom of the cup.

Yang Wenli held the cup and said to Wang Rucheng: "This is potassium sulfate, and the other cup is relatively pure concentrated nitric acid."

This is a miracle substance, it is a strong solvent, and at the same time the basic raw material for high explosives, propellants, detonators, etc. ”

"Are there many kinds of explosives?" Wang Rucheng asked puzzledly.

"Yes, there are dozens of explosives alone, propellant is a flammable substance, and detonating charge is also a kind of explosive, but it is extremely sensitive, as long as there is a needle prick, sparks, impacts, etc. will explode, which is most suitable for detonating charges for safety explosives." Yang Wenli then went on to say.

Next, he used three glasses to evenly divide the cup of concentrated nitric acid, and said to Wang Rucheng seriously: "The next step is very dangerous." We had to make three substances, each of which was dangerous and had to be done with care, so we had to experiment separately. ”

While speaking, Yang Wenli took the other two cups of nitric acid far away, and after returning, he continued: "The first is nitrocellulose, which is a very flammable substance, that is, soak it in cotton, gently take it out and dry it, pay attention, this step should not be too fast, otherwise nitrocellulose will burn." ”

After Yang Wenli finished explaining, he just wanted to do it, Wang Rucheng hurriedly said: "Great Commander, I'll do it!" If only you told me what to pay attention to. ”

Wang Rucheng heard him say that it was very dangerous, so he stepped forward and was willing to be the guinea pig himself.

Wang Rucheng's actions made Yang Wenli very satisfied, and he said with a smile: "Okay! You do the experiment, and I'm watching from the side. At this step, it should be noted that the metal camera should not be used to enter the nitric acid, otherwise an explosive substance will be generated, because the metal will react with nitric acid, and clean chopsticks can be used. ”

According to what he said, Wang Rucheng slowly used chopsticks to carry the snow-white cotton and soaked it in nitric acid, and then gently took it out, put it aside to dry, and so on, and finally used up the nitric acid in the cup.

"Archon, what's next?" Wang Rucheng was very interested, and as soon as he finished his work, he asked again.

"The next step is very simple, but it is also very dangerous, put the animal fat into nitric acid to dissolve, gently stir with a glass rod, you get a high explosive "nitroglycerin", note that when the oil is dissolved, the temperature will be generated, the temperature is higher than 78 degrees, it will explode violently, so the grease can only be added slowly in a small amount, touch the cup with your hand to not burn your hands.

In the future, when making a large number of products, it is best to make them separately, a small amount at a time, and add more manual production, so as not to cause major explosion accidents. ”

Wang Rucheng cautiously complied with his words until the nitric acid in the cup turned into a soup-like substance, and Yang Wenli instructed him to add diatomaceous earth to passivate and reduce the sensitivity of nitroglycerin, which obtained a safe explosive.

This is an invention of the Swedish chemist Nobel after sacrificing three family members, and Yang Wenli easily used it, and even the patent fee was saved, which is the advantage of the reborn.

Nitroglycerin is too sensitive and explosive to be used as an explosive, but safety explosives also have disadvantages, that is, they are too stable, whether it is a collision, acupuncture or ignition, it will not explode, even if it is burned on a coal fire, it will not explode, only with an appropriate amount of lightning mercury detonated.

This forced Yang Wenli to develop thundermercury, so he took the most initiative and began the next step of the experiment.

"Ru Cheng, first use that distillation kettle to distill dansha, just like steaming rice, steaming through water.

Dansha is also called mercury sulfate, mercury content is more than 80%, we just need mercury, also called mercury, is a very special, liquid metal at room temperature, remember, when distilling, be sure to go away, because mercury is highly toxic, smelling a small amount may be fatal. ”

After Yang Wenli said this, he walked away from afar, and before long, Wang Rucheng also finished his work and walked over, there is no danger in this step, you can watch from afar.

Wang Rucheng was still very interested, and he couldn't wait to ask, "Great Commander, what's next?" ”

"Don't worry! Things have to be taken one step at a time. Ru Cheng, I can tell you! I'll only do one experiment, and then you'll organize a large number of people to make it, and I'll try to make grenades and bomb canisters, and I'm too busy to finish it.

I spend too much time on scientific research, and I don't have time to take care of the troops, so I'm putting the cart before the horse. Yang Wenli said with feelings.

"Great Commander, I think that these scientific research are very necessary, although our Black Armor Army has excellent combat strength, but the number is too small, so we must retreat to Changsheng Island to prevent the encirclement and suppression of the Jiannu army.

If we add advanced weapons and equipment, then we do not need to be afraid of Jiannu, and we can unify the Central Plains as soon as possible and create a glorious and prosperous era of our Huaxia. Wang Rucheng bowed deeply and suggested.

"No, the Ming Dynasty has not declined, at this time into the Central Plains, can not get the support of all the people in the world, belongs to the world, for me not to take, our army must also Taoguang obscure, choose a remote place, and strive to train the black armor army, so that it can fight, free gallop, no longer afraid of the Jiannu cavalry, and continue to increase the number of high-quality soldiers, expand the scale of the black armor army, to increase the size of the servant army, so that our army reaches the scale of 20,000 soldiers, when the time comes, we will return to Liaodong, first eliminate the Jiannu, and then unify the Mongolian tribes, and finally take advantage of the momentum, Arriving at the Central Plains is the best policy. Yang Wenli said what he thought in his heart.

"The Great Commander is far-sighted and has been taught!" Wang Rucheng was encouraged and sincerely admired when he heard this, and he bowed deeply and bowed in convincing.

"Hehehehehe!" ……

Yang Wenli's hearty laughter resounded in the workshop, which lasted for a long time.
