Chen Xian then conducted a continuous shooting test, in which he asked a soldier to use an arquebus and a soldier to use a three-eyed gun, and let the two of them shoot continuously for half an hour.

Finally, a soldier with an arquebus fired almost three times as many bullets as a soldier with a three-eyed gun.

In the long shooting competition, another disadvantage of the three-eyed gun compared to the arquebus was also exposed, that is, the poor aiming performance.

100 meters distance, shooting humanoid targets, even if the arquebus test shot apprentice marksmanship is not good, there is almost half of the hit rate, with a three-eyed gun, the bullet floats very strongly, ten shots, it is difficult to have a shot, it all depends on luck.

Thirty-meter target, the three-eyed gun can hit one out of three shots, but this distance arquebus can almost do 100 shots.

After this series of experiments, the apprentices were finally convinced and no longer asked for the Three-Eyed Gun.

Of course, you can't do without gunpowder if you have a gun, otherwise the musket is a burning stick, so the development of gunpowder is carried out simultaneously with the development of the arquebus.

When the trial production of the arquebus was successful, Chen Xian already had his own black powder production workshop.

Black powder is a mixture of nitrate, sulfur, and carbon.

The recipe for black powder, the production of nitrate, sulfur, and carbon is almost essential for most time-travel novels, and it is also in the database of the Internet writer.

Nitrate has been widely produced and applied in the Song Dynasty, and this kind of thing is very important in alchemy, and it is one of the main gunpowder.

Nitrate is also used in traditional Chinese medicine, and it is also used in leather making.

But the amount of this thing is relatively small, during the honeymoon period of the relationship with the Yang family, Chen Xian asked the Yang family caravan to help go to Laiwu County to purchase, but he soon found that the purchased things were either very expensive or wrong.

For example, the nitrate purchased from the Chinese medicine shop is miscanthus nitrate most of the time, and the nitrate in the leather goods store is not even miscanthus nitrate.

There is no way, Chen Xian can only use the soil method to boil nitrate.

The so-called boiling nitrate is to extract fire nitrate from nitrate.

The source of nitrate, the boiling method of fire nitrate, and the mobile phone of the online writer all have detailed information, and Chen Xian only needs to read the book according to the script.

Nitrate is generally produced in latrines, pig and cattle pens, corners of old houses, cliffs, caves and other places.

On the one hand, Chen Xian collected nitrate from Dongzhuangzi through his apprentices, and on the other hand, he sent people into the mountains to collect nitrate from cliffs, caves, and other places where there was humus but would not be washed by rainwater.

This is because the process of decay of organic matter under the action of nitric acid bacteria will produce nitrate, so humus is often rich in nitrate, but nitrate is relatively soluble in water, so rainwater will carry away the nitrate in the humus.

He also tried to stack a compost heap for a long time to see if he could produce his own nitrate.

The principle of nitrate production is that after the organic matter in the soil is corrupted, nitric acid is generated through the action of nitrite bacteria and nitric acid bacteria, and then combined with potassium and sodium ions in the soil to form nitrate.

The process of composting, in fact, is also a process in which nitrite bacteria and nitric bacteria work, as long as the composting time is long enough, a large amount of nitrate will be produced.

The so-called nitrate boiling is to mix nitrate and plant ash in a certain proportion, heat water and stir to dissolve, and filter out insoluble substances.

The filtered solution is boiled, and during the boiling process, the different solubility of impurities such as potassium nitrate and sodium nitrate at different temperatures is used to remove the magazine at different temperatures and precipitate relatively pure potassium nitrate.

Using this principle, after multiple dissolution and analysis, relatively pure potassium nitrate can be obtained.

Compared with the difficult procurement of fire and nitrate, the procurement of sulfur is much easier.

Sulfur is widely used in traditional Chinese medicine, and it is the most important drug for the treatment of skin diseases in this era, so as long as it is a pharmacy, there is this thing, and sulfur is also an auxiliary product for refining gold and silver, and the amount is not small.

The most important thing is that Laiwu itself is a source of sulfur.

There are two sources of sulfur, one is natural sulfur purification, and the other is extraction from pyrite.

The method of extracting sulfur from pyrite was recorded in the Tiangong Kaiwu written by Song Yingxing of the Ming Dynasty, and this method was actually used as early as the Song Dynasty.

Laiwu is rich in coal and iron, and also produces pyrite, and there are workshops for making sulfur in the county.

With nitrate and sulfur, there is no need to talk about charcoal.

When Chen Xian completed the mass production of muskets and gunpowder, it was already the midsummer of the seventh year of Taihe.

……

During this half year, there was also a small episode.

The eight hunters who were rescued and released by Chen Xian came to Chenjiazhuang again more than a month later, and they brought a lot of furs and bacon as gifts to thank Chen Xian for saving his life.

One of the hunters was the younger brother of one of the hunters who attacked Chen Xian last time, and he brought the hunter's thanks and kindness.

Chen Xian was naturally happy to have one less enemy, he met with this group of hunters, accepted their gifts, and gave them a batch of high-quality machetes in return.

This kind of machete is Chen Xian's imitation of the shape of the dog-legged knife produced by cold steel in his hand, the front end of the blade is wide and thick, the back end is narrow, the back of the knife is a recurved arc, the blade is S-shaped, and the tip of the knife is facing forward, which is not only extremely powerful to chop, but also very easy to stab.

When imitating, Chen Xian enlarged the volume of the knife, which was originally more than a foot long, to more than two feet long, and then equipped each soldier with one as a secondary weapon.

This kind of knife Chen Xian also adopted the steel-clad method of 100 steel and wrought iron forging, with soil quenching, the quality is not inferior to the katana, and the practicality is even better.

The hunters were even a little terrified when they got the sword, they felt that the bacon fur they brought was not worth one percent of the sword.

Chen Xian struck while the iron was hot, and proposed to the other party to use this machete to exchange for nitrate.

After listening to what Chen Xian introduced about the nitrate, the hunters almost felt that Chen Xian was crazy, and they actually exchanged this treasure knife for soil!

Although they thought it was incredible, of course the hunters would not refuse this good thing, and immediately agreed.

Chen Xian made an appointment with the other party to inspect the nitrate, and said that only the nitrate that passed the inspection could be replaced.

The hunter originally felt that this thing was picked up for nothing, so naturally he would not refuse anything.

After talking about business, Chen Xian entertained the hunters for a drink.

After drinking some wine, a hunter tentatively asked Chen Xian if he would accept their Orion's children as apprentices.

It turned out that the hunter had an elder brother who was injured and died during a hunt, leaving his three sons helpless.

Chen Xian immediately said without hesitation, "Collect, why don't you accept it, there are only two in my shop, the first is not to accept the children of the landlord Haoqiang, the second is not to accept scholars, and the others are all accepted." ”

Chen Xian felt that at his level, he brainwashed some illiterate teenagers to make a living, and the scholars were forgotten, while the children of the landlords were difficult to control on the one hand, and there were few such people who were illiterate.

Chen Xianzheng was worried that he could not recruit apprentices, and even if he publicized his favorable conditions for recruiting apprentices, many hunters were greatly tempted.
