Chapter 142 0139 [Firearms]

Flipping through the pages, I saw the chapter on firearms in Volume [-] of the previous episode.

Han Zhen's eyes were fixed, and he looked carefully.

There are many types of firearms recorded in the book, such as turkeys, bamboo fire harriers, iron mouth fire harriers, gunpowder whip arrows, muskets, smoke blankets, poison smoke blankets, thunderbolt fire blankets, artillery, etc., and each of them is accompanied by pictures, and Notes explaining the power and effects of each firearm.

Seeing this, Han Zhen couldn't hold back anymore and laughed out loud.

Zeng Gongliang is an idiot, but he was ordered to compile this book, and the Song Renzong Zhao Zhen who was printed all over the world is not clean.

The firearm hits by surprise, and catches it unprepared. You write down the power and the effects of various firearms, what a fart!

Looking further down, there are even more outrageous things.

It turned out to be the formula for gunpowder...

[Gunpowder Method Jinzhou sulfur 14 taels, nest yellow seven taels, flame nitrate two and a half catties, ephedra one tael, dried lacquer one tael, arsenic yellow one tael, fixed powder one tael, bamboo rutabaga one tael, yellow dan one tael, Half liang of yellow wax, one part of clear oil, half liang of tung oil, 14 liang of turpentine, and one part of thick oil. 】

Han Zhen frowned slightly, and muttered to himself: "Does gunpowder need so many materials?"

Isn't there only sulfur, saltpeter and charcoal?
Great In order to prevent the explosion caused by too much dust during manufacturing, it seems that there is no need for anything other than adding some egg whites.

This is dry lacquer and turpentine... I'm afraid it's not alchemy.

Give it a try first.

Han Zhen took out the pen and paper and copied the formula materials, then called a soldier and asked him to go to the county to purchase.

"County magistrate, I don't know so many words."

The soldier took the paper with a perplexed expression on his face.

Although he has been taking night classes during this period of time, he has only mastered less than a hundred words, and they are all everyday words.

Right now on this piece of paper, most of them don’t know each other.

Han Zhen said: "If you don't recognize it, you can ask the subordinate officials of the county government for help, and say that I ordered it."

"I see."

The soldier nodded and rode out of the barracks on a horse.

Not long after, the soldier came back with a bag of materials.

Han Zhen took the materials and thought about it, but he didn't dare to make it in Baihutang.

After all, it is gunpowder. If something happens, it will be troublesome if the Baihutang is burned down.

Bringing tools, he walked all the way to the open space deep in the barracks.

This open space is located on the edge of the foot of the mountain, next to the forest, 200 meters away from the nearest building to the barracks, so you can toss about it casually.

Taking out the materials one by one, Han Zhen dug out the "Wu Jing Zong Yao" and followed the steps recorded in the book.

[Right: Jinzhou Sulfur, Wohuang, and Flame Salt are pounded together, Luopihuang, Dingfen, and Huangdan are grinded together, dry lacquer is pounded into powder, Zhuru and Maru are slightly fried into powder, yellow wax, turpentine, clear oil, and tung oil and thick oil are boiled together to make a paste.Boil together to make a paste.Before entering, the medicine powder is swirled and mixed evenly, wrapped with paper five times, bound with hemp, not to mention melted turpentine.Using cannon fire, there is also the method of releasing poison and smoke balls, and attacking the goal with fire. 】

After working hard for nearly half an hour, Han Zhen finally made the firearm.

The shape resembles an enlarged and bold firecracker. In order to make the paper fix the gunpowder more tightly, hemp rope was tightly wrapped around the outside several times.

The reason why it took so much effort to make it was to see how powerful Song Jun's firearms were.

The ancients were a little bad. When describing numbers and some scenes, they tended to exaggerate.

For example, Zeng Gongliang recorded in "Wu Jing Zongyao" that the sound of gunpowder explosion was like thunder, and all internal organs were ripped apart... According to the records, the power is almost as powerful as the high-explosive grenades of later generations. .

At this time, Nie Dong's voice rang in his ears: "Is the county magistrate doing alchemy?"

"Make gunpowder."

Han Zhentou replied without answering.

Nie Dong was taken aback for a moment, then suddenly said: "Oh, the county magistrate makes firearms!"

Hearing this, Han Zhen asked curiously, "Have you used it?"

Nie Dong looked disgusted and said: "Of course I used it, this thing is not very powerful, and it may hurt myself if I don't do it."

"Since you've used it, you can order this."

As Han Zhen said, he handed over the large "firecracker" in his hand.

He really didn't know what to do with this firearm he made by himself.

"Order!"

Nie Dong took over the firecracker, picked up the torch hanging on his waist, and directly lit the fuse.

Seeing that the fuse was ignited, but Nie Dong was still holding the firecracker, Han Zhen hurriedly reminded: "Throw it away!"

"You don't need to throw it away, the last general said, this thing is not very powerful."

Nie Dong waved his hand indifferently, with a relaxed expression on his face.

Han Zhen raised his eyebrows and retreated a few steps calmly.

According to the dosage of gunpowder in later generations, such a big one would be enough to kill them both.

Finally, the lead burnt to the end.

puff!
Like a loud fart.

Immediately afterwards, puffs of thick black smoke rose and soon filled the air.

"Cough cough."

Han Zhen coughed twice, in disbelief: "The firearms in your Western Army are also like this?"

Is this fucking explosives or a smoke bomb?
The sound of the explosion is not as loud as a fart.

Then throwing away the firecracker in his hand, Nie Dong replied: "It's almost the same, but some are more powerful, can blow up earthen jars, and shoot out the caltrops buried in the earthen jars."

Han Zhen asked: "May the barbed caltrops shot out hurt people?"

Nie Dong laughed and said, "Everyone on the battlefield wears armor, not to mention iron armor, even leather armor can't be shot through, how can it hurt people."

Outrageous!

Han Zhen now understands why Zeng Gongliang published the gunpowder formula in the book. Emotions are useless at all.

Gunpowder in the Northern Song Dynasty was unreliable. It seems that we still have to make black gunpowder ourselves.

"Go to the warehouse and get some charcoal, saltpeter, and sulfur."

Hearing Han Zhen's order, Nie Dong turned and left without saying a word.

Soon, he came back carrying three sacks.

Seeing that Han Zhen didn't seem to give up, Nie Dong couldn't help persuading him: "County magistrate, firearms are heretics, and training soldiers is the right way. Our Qingzhou army is full of food and pay, as long as we practice properly, our combat power will be unparalleled!"

"I see, you go ahead."

Han Zhen waved his hand.

Knowing that he didn't listen, Nie Dong turned and left helplessly.

The proportion of black powder, Han Zhen remembers, is 74.64% of potassium nitrate, 11.85% of sulfur, and 13.51% of charcoal.

The first step is to boil the nitrate.

Whether it is saltpeter or sulfur, the higher its purity, the greater the power of the explosion after it is made into black powder.

It is very simple to boil saltpeter. First, grind saltpeter into small pieces and put them in a pot to boil.

The ratio of water to saltpeter is about 1:0.7.

Wait until the water is heated to about [-] degrees, skim off the froth, filter it again, and wait for the saltpeter to crystallize.

By repeating this three times, saltpeter with higher purity can be obtained.

This big pot of saltpeter needs to be boiled for at least a while.

Taking advantage of this time, Han Zhen picked up the copper still and prepared to start purifying the sulfur.

This set of stills was specially ordered by a craftsman in a government-run workshop some time ago, and it is used to distill high-grade liquor.

With high-concentration liquor and allicin, the death rate of soldiers will drop sharply in the future.

In addition, Han Zhen also ordered large quantities of wound medicines from the two medical clinics in the county, and at the same time invited doctors to the army every now and then to teach simple trauma treatment.

Light the stove, put the still on the fire, and add sulfur.

Han Zhen forgot whether it was three hundred degrees or four hundred degrees, the sulfur would liquefy and boil, continuously producing a large amount of sulfur gas.

After the gas is condensed and dried, it is the purified sulfur.

These two steps are very critical. The purity of saltpeter and sulfur is directly proportional to the explosive power.
