"Dashuai, somehow laughing!"

Chen Kefu laughed, everyone who laughed was confused, and the cavalry captain Luo Lin couldn't help but ask.

smiled mysteriously at everyone, and didn't explain any more, Chen Kefu, who was in a good mood, directly said to everyone, "Li Changshi, in the past, the logistics in the army were all managed by you, do you know that there are sulfur and saltpeter in the army?" ”

Black powder is simple to make, and there are only three kinds of materials required: sulfur, saltpeter, and charcoal. The material is simple, the key is still the ratio of the three things, as long as the best ratio is found, then these three things are mixed, it becomes a necessary item to kill people and goods.

Among the three materials, charcoal is easy to get, just cut some trees and burn charcoal. The key is still sulfur and saltpeter, these two things are not ordinary things when they hear the name, and they mainly belong to the practice materials often used by those Shinto practitioners.

Now living in Liaodong, Chen Kefu is not sure that there will be these two things in the city.

Li Jie has always been the logistics chief of the army in the past, and he is also very familiar with all kinds of materials and materials, hearing Chen Kefu suddenly ask this, he thought about it carefully and said, "Sulfur is a flammable thing, and rockets and other materials in the army need this material, and now there are many in the military warehouse, but I remember that there are some saltpeter in the medicinal material warehouse, but there are not many of them." ”

Sulfur is a must-have item when making rockets and engaging in fire attacks, so there is a large amount of sulfur in Liaodong City at this time. However, there are not many saltpeter things, and the only thing that exists in the medicinal material warehouse is also as a medicinal material.

Chen Kefu couldn't help but shake his righteousness after hearing this, it's really nonsense. No matter how you look at this saltpeter, it is a chemical product, and it has nothing to do with the medicinal materials that cure diseases and save people. However, not only did those Taoist priests use these things to refine the so-called elixir, but even those doctors actually used them to treat diseases and save people, and they really didn't know whether they were saving people or killing people with such prescriptions.

There are sufficient quantities of charcoal and sulfur, and now there is also a small part of saltpeter, which can also allow Chen Kefu to conduct an experiment immediately. After all, although he knew the formula of this black powder, limited to the purity of the material and other reasons, he could only make a gunpowder formula with the best effect through continuous trial and adjustment.

"Li Changshi, you will immediately send all the saltpeter to my handsome tent in the north of the city, and in addition, you will also get a hundred catties of sulfur, and also, get some grass ash and charcoal."

It was sulfur, saltpeter, plant ash and charcoal, which made the generals feel very curious. How do these materials sound like the alchemy materials of those Taoist priests, could it be that the handsome man actually wants to alchemy?

"Dashuai, do you still know how to do alchemy?" Shen Guang asked curiously.

Chen Kefu smiled mysteriously, "That's right, Ben Shuai is planning to refine a pill, and this pill will be thundered all the time.

However, this elixir is not used to eat, but to attack the Liao people, and then you will just wait to see a good show. Let's disband all the governors, go back and hurry up to train their soldiers and horses. ”

The largest tent in the military camp north of the city that can accommodate 100 people is Chen Kefu's handsome tent.

At this time, a hundred steps away from Chen Kefu's tent, more than 200 people had already been surrounded. At a distance of one hundred and fifty paces, there were two whole groups of 100-strong military police officers in black clothes. A hundred paces closer to the Great Tent stood two whole groups of a hundred men of the Marshal Guard Battalion. Everyone was facing a great enemy, spear in hand, and their eyes were wide open, staring closely ahead.

The commander has an order, and without his warrant, no one is allowed to come within a hundred paces of his tent.

In the big tent, there are still dozens of people, including craftsmen, doctors from the medical camp, and Chen Kefu's guards, and Chen Kefu is also standing in the big tent at this time.

The handsome tent, which was originally majestic and neat, was now filled with smoke, and a foul smell filled the tent. Chen Kefu was wearing armor on his body, and even his face was covered with a large piece of white silk, and the whole person was indescribably weird.

In the handsome tent that was originally covered with blankets, an earthen stove was erected. There is a large pot on the earthen stove, and on the side of the stove are several large vats with wooden sticks, on which are placed a large huā basket made of wicker, and two or three layers of fine woven mats are placed on the bottom of the basket.

At this time, several soldiers were using the water in a large tank on the side to pour the nitrate in the huā basket huā and drench it, and then slowly watered it, the nitrate in the huā basket was soaked, and the water slowly seeped down, and the dripping nitrate seeped down, and the nitrate water was brown and yellow, and it leaked almost from time to time, and then the water was drenched, and the nitrate seeped dripping again. This basket of soil is almost filtered, and then a basket of nitrate is loaded, and then the nitrate water is poured through and leaks down. ,

The basket is full of nitrate, not saltpeter, originally Chen Kefu thought that Li Jie said that there are a lot of saltpeter in the army. After the results were delivered, it was found that many of his saltpeters turned out to be only a few small

bag, that is, one or two pounds. That little saltpeter has been tossed up by Chen Kefu in two or three experiments. As a last resort, Chen Kefu suddenly thought of another trick, that is, scraping nitrate soil on the earthen walls of those horse pens and thatched houses in the city.

Near this thatched house, on the land where soldiers love to pee everywhere on weekdays, when the sun is shining, there will be patches of white huāhuā alkali, and from a distance, there is still a crystal light, these things are not noticed at all on weekdays. As a result, Chen Kefu, who had no nitrate, hit the idea here, and he asked the soldiers to scrape off the nitrate and bring it back to boil.

In this way, it was leached and filtered basket by basket. When the nitrate in the vat was full, Chen Kefu hurriedly beckoned his soldiers to make a fire and boil the nitrate. The process of boiling soil nitrate, that is, the process of drying part of the water in the nitrate water by heating, and finally pouring the soil nitrate crystallization into the tile pot. In order to make full use of the fire, it is generally built with two eye stoves, and the nitrate can not be too vigorous, most of them are holding the firewood and fire, and the nitrate water is dried by continuous heating.

When it is heated to about 50 degrees, the crystals have all turned into gross nitrate, Chen Kefu is busy asking those soldiers who are smoked like the prince of the stove to add fire to boil, and when the water is reduced, he is busy taking it out and pouring it into the pot, and finally pouring the boiled marinade into the tank for crystallization, at this time it is water nitrate. The water nitrate is heated again to make the water continue to evaporate, and finally poured into the pot and cooled to crystallize into soil nitrate.

"It's done, it's done." Chen Kefu looked at the saltpeter that finally came out of the soil method after a few days of busy work, and said with a smile.

In the big tent, dozens of people stretched their necks, looking at this thing that took a lot of effort to come up, and said with some suspicion, "Dashuai, this is good?" Didn't you say that once Dan practiced well, he could be able to shake the sky and thunder 1 and still be used to kill and injure the Liao people? Why doesn't this thing look special? ”

Chen Kefu smiled, "You just wait to watch a good show, and I will definitely be able to shock you then." Quick, get some of the sulphur and charcoal over there. The charcoal and sulfur had already been ground into powder, and Chen Kefu took some freshly boiled soil nitrate from the pot and crushed him into powder. After the three materials were ready, he took out a small medicine scale used by the military doctors, and arranged it according to the ratio of nitrate, sulfur 1O, and charcoal 15.

In order to pursue efficiency, Chen Kefu directly put the freshly boiled nitrate into it, but fortunately, in the past few days, the people in the city have rushed out and scraped all the corners of the walls and corners of the city, which really made a lot of nitrate. It took a few days to boil out thousands of catties of nitrate. After mixing it with sulfur and charcoal in proportion, he suddenly had more than 1,000 catties of black powder.

Looking at the black powder that was ready, several doctors who were called over to participate were more sure that Dashuai was indeed alchemy. It's just that such a black medicinal powder can really be as mysterious as he said, but everyone doesn't believe it.

"Quick, pour all this black powder with water, remember not to get too much water, just get wet. When they are all wet, they are dried in a large pot in fine granular form. Dozens of soldiers were busy and began to operate according to Chen Kefu's steps again, and a doctor was not small

Heart, waiting for the wet black powder in his hand, withdrew a little to the stove fire. In the midst of the fire, there was a burst of thought, and sparks splashed everywhere. The group of people in the tent were taken aback, and even Chen Kefu was taken aback, the doctor had a box full of black powder in his hand, if it was all poured into the fire, then it was very likely that the entire big tent would burn at once.

With so much gunpowder in their tents, they might really have to sacrifice their lives for the cause of science.

Chen Kefu, who was in a cold sweat, hurriedly asked everyone to move all the gunpowder out of the tent and take a little bit of it in to bake it at a time.

After the first batch of black powder particles was finally grilled dry, Chen Kefu hurriedly took it to another tent a few hundred steps away. In fact, after the black powder is prepared, it does not need to be wet to make particles to dry, but after it is made into granules, it burns more fully and violently than powdered black powder, because the fire will spread on the surface of the granular gunpowder, which will greatly enhance the burning speed of the sharp powder and obtain greater power by reducing the reaction time.

Carefully put the black powder into a clay pot, although the black powder is also gunpowder, but the power is not very strong. In order to make up for this shortcoming, Chen Kefu made ten catties of gunpowder for the first finished product. Next, he made five or six more, and plugged in a fuse made of twine wrapped in black powder.

"Marshal, a herald has been sent to inform all the generals above the general level in the army, and a site has been cleared twenty miles outside the north gate, and there are soldiers from our guard battalion guarding it, so you don't have to worry about being known."

"Okay, I'll let you have a good look at the power of the earth-shaking thunder, remember to cover your ears then, don't be scared stupid." Chen Kefu smiled and asked a few guards to take the clay pots and go to the test explosion site ten miles north of the city.
