After Zhang Guoan signed contracts with other businessmen who came here one by one, he felt really comfortable. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

He is obsessed with the barrel of a gun, however, he only uses it to uphold the laws and contracts he has set out, not to violate them.

The Extinguishing Gun has finally completed the final few steps.

They relied on precision casting and final manual processing to complete the mold task.

They hurried to inform Zhang Guoan.

When he came, the shiny lead bullet was still warm, and he asked for a micrometer and measured it, and it was good, within the scope of application.

At this time, he not only had to look up at these craftsmen with thick hands and feet, but they always had red silk in their eyes, they just lacked the driving force and suitable raw materials, so with the help of these simple knives, they could do it so well.

If you make up the basics, it will be against the sky.

They went to the training ground of the Liuqiu Guards together and began to test the gun, which made everyone look forward to it, and those members who had just been transferred were even more excited, this is a kind of gun to kill you!

Zhang Guoan was very calm at this time, he first filled one gram of propellant, then pulled out the gun strip, pushed the lead bullet into place with a little force, and then inserted the gun strip back, put on the fire cap he brought, and gently pulled up the hammer.

He felt the V-spring stuck on the trigger, so he raised his gun and aimed at the target a hundred meters away, which was the original row of wooden walls, which was used to train the team members to understand ballistics.

After aiming at a position, he pulled the trigger.

Those blacksmiths and carpenters, as well as those team members, only heard the crisp sound of gunshots, and did not see the green smoke coming out, but they saw that a fist-sized hole suddenly opened in the wooden wall more than sixty paces away!

Zhang Guoan endured the pain. He didn't touch his shoulder, blaming himself for not sticking to the handle of the gun, and, when the fire cap sounded just now, he unconsciously closed his eyes, and the place where he shot was a certain distance from the target he wanted to hit.

But others are ignorant. They were frightened by what they saw.

Hu Zhenbei's blacksmith's tongue was spit out, looking at the power of the lead bullet, it would not be a problem a hundred zhang away!

Ah, I'm glad I didn't say anything.

Captain Bao Wei was the first to jump over, his face full of excitement, and said, "Master Zhang, can you let me try the gun?!" ”

After Zhang Guoan instructed him to load, he let him shoot in a horizontal position, and he obediently lay down. Then he was given another fire cap, and when he saw that his shoulders were tightly pressed against the handle of the gun, he made a gesture that he could shoot.

Seriously, he's not as well suited to fiddling with such a weapon as his teammates.

Captain Bowie fired steadily, also with a fist-sized hole!

The eight and a half sons fired shots in turn, and in the end, the blacksmith Hu Zhenbei seized the opportunity and fired a shot.

At this time, Zhang Guoan observed the chamber of the gun. There was now a thin layer of lead hanging in the rifling, and barely enough to shoot a round or two.

Zhang Guoan knows. If you don't want to hang too much lead, you can add some tin to the lead, but it is too hard and hurts the rifling------ it is better to hit more than a dozen rounds and then brush it with a copper brush.

Zhang Guoan did the math. A gun plus the equipped bullet mold takes about ten days for two craftsmen to process.

Recruiting craftsmen again is the right way, and these dozen are not enough.

The gun was handed over to Captain Powey, and by the way, it was accompanied by a batch of leather goods sent by the leather workshop in advance.

Zhang Guoan put Captain Bao Wei on first, and really improved his momentum. But it was not as good as he thought, he did not have thin tweed in his hands, nor did he have cotton and linen blended clothing, so he could not make that kind of structured effect.

Captain Bowie felt very good, he kept touching the leather goods on his body, patting the leather bags on both sides, and he was a little proud.

Zhang Guoan immediately found that the military hats were not good-looking, they were all wearing bamboo hats------ a bit like the Vietnamese militia in the world, it was really not good-looking.

He remembered the corn stalks and straw hats of the world, and if they were paired with a hat belt, it would be better than this.

Captain Bowie held a gun and became everyone's demonstrator, allowing them to touch and watch.

Regarding the construction of the guard, in addition to trying to recruit another blacksmith, Zhang Guoan was ready to pause for a while and wait for the second batch of transactions with the Great Song Dynasty to be completed.

He also had to get the nitrified dry oil out, otherwise it would be too much trouble to mine with black fire/medicine.

When Liuqiu sent back a 10 percent fee from the various mine owners and factories in the northern estuary area, they also said that they had found a small coal mine with too narrow an entrance, otherwise more could be excavated.

Zhang Guoan has the latitude and longitude coordinates of the large coal mine in time and space, but with his current ability, he can't reach it at all.

He only knew that there was a small coal mine like that, but he didn't know where it was.

At this time, only gelatinous dana explosives/charges made of nitrated dry oil and nitrocellulose can be used.

The problem of glycerin is easy to deal with.

All glycerin is recovered from the by-product of whale oil soap making.

In the quiet breeding and seedling breeding base, the soap handicraft industry has now begun, and as long as soda ash and salt are available, soap is not a problem.

The related products will be launched in the third batch when they are traded with Da Song.

In the saponification reaction of whale oil, the reaction products are divided into two layers: the upper layer is mainly soap and a small amount of glycerin, and the lower layer is waste lye, which generally contains 9-16% glycerol.

Zhang Guoan can only cook it repeatedly, but fortunately he does not need any catalyst.

In the eyes of the Great Song people, he was shrouded in smoke again.

Finally, he strained it with fine charcoal powder to get a relatively pure, colorless and odorless glycerin.

Quiet and unhappy, he said: "The nitrified dry oil explodes at one hundred and seventy degrees, you really don't want to die!" Do you have a way to get hold of the temperature now? ”

Zhang Guoan hurriedly told her about the process of thermostating the method he designed, saying: "I have ice cubes, which can be made into water at a lower temperature, and more importantly, we also use nitrocellulose to adsorb, so we don't have to think about how to preserve it, which is very safe." ”

Quietly said: "If you insist on making it, then you will let me do it with you, this is a simple chemical experiment------ or I won't let you go, I will keep the glycerin for wiping my face and making cured meat!" ”

Zhang Guoan had to agree, and at this time, he reduced the amount of production by one share.

The two of them placed all kinds of equipment directly in the ice-making cave, and ordered that no one should enter.

In this way, they processed the gummy dana explosives in small portions, one at a time, and after about twenty days, they got ten kilograms of product.

Quiet stopped at this time and said, "These are enough for you to open a mine, right?" I don't know how big the mine is. ”

Zhang Guoan's attempt to use it for military purposes failed.

He had to mix some nitric acid/potassium with wood flour, which is used here as an oxidizing agent, and wood flour can act as an accelerant and loosening effect.

At this time, it can be detonated directly with the fuse. (To be continued.) )
