He asked Dong Ce for a long hemp rope, tied a knot buckle at the end of the end, and then picked it on his hand, and after finding the feeling, his hand shook, and the long rope flew out, and it was just caught in the corner of a buttress on the pier. d-m

Qiu Ping tested the strength of the rope, and then climbed up along the rope.

The four walls of this pier are almost straight up and down, even if there is a foothold, it is only the kind that is only a finger's width, and it is impossible to stand at all. And Qiu Ping climbed the rope, but his seemingly fat body was extremely agile, like a fat cat, and he climbed up in three or five clicks.

He came down from the pier platform and said with a smile: "Su Rili often goes to some big houses, and now they are building the courtyard walls higher and higher, three or four feet, if you don't have this rope buckle, you really can't climb up." ”

Dong Ce smiled and praised: "Very good, very good!" ”

Qiu Ping showed his hand, and Liu Facheng did not show weakness, he would imitate the sounds of various animals.

Roosters, dogs, donkeys, horses, cows and sheep, they know everything, and they learn very similarly.

"This is the so-called chicken and dog thief!" Dong Ce said secretly in his heart.

Both of them are trying their best, and Dong Ce also knows that they must not have taken out their real skills, but now it seems that these two people are usable.

Dong Ce called them to a room and discussed secretly for more than an hour, and after the two said goodbye, they quietly went out of Anxiangdun.

= 1 = Ben = Read = Novel

Neither of them knew how to ride a horse, so Dong Ce didn't give them horses, they just carried the fifty taels of silver in their arms.

Even if these two people ran away, Dong Ce only lost fifty taels of silver.

And if they can maintain their loyalty, then Dong Ce will get two outstanding intelligence officers.

……

"Grass your grandma, Lao Tzu finally tossed you out!"

Du Jianhe touched the sweat on his forehead with his sleeve, let out a long breath, and couldn't help but let out a strange cry excitedly.

At this time, it is already November, and it will be December on the solar calendar in the future. The land of northern Jin has long been a cold and frozen, withered grass is decaying, and when you get up in the morning, you can see that a layer of hoarfrost has formed on the ground. It's already cold outside, the temperature is already below zero, the cold wind is howling, and there is an indescribable chill on the body.

Lead clouds were piling up in the sky, and there was no telling when a heavy snow would come.

The workshop at Rock Fort was in full swing. The flames in the dozen or so large iron furnaces drove away the cold, but the heat wave was overwhelming.

The tinkling sound of the tinkling sound is even more lively. Everyone was busy with their own business, either building knives and guns by the fireside, or striking something with a little hammer on an anvil.

It is lively here, and the carpenter area next to it is not deserted, with people coming and going, and shouting and shouting from time to time. Now there is work everywhere, some are building city walls, some are digging ditches, some are building bridges, and the amount of wear and tear of various tools is very large. These simple tools can be built by the carpenters of Rock Castle, and they are one order after another in business.

Their enthusiasm for work is also very high, Dong Ce's implementation of the craftsman classification system has included the two groups of blacksmiths and carpenters, Dong Ce has already spoken, whoever builds more tools, the better, who can be promoted to a first-class craftsman.

The status of a first-class craftsman and the monthly money of one or two pieces of silver that increases every month are a great temptation for craftsmen, who would not be self-motivated? Besides, the two first-class craftsmen in the blacksmiths, Zhao Tiean and Du Jianhe, are now the little leaders, which also makes others have some strange thoughts.

No matter how big an official is, it's always an official, isn't it?

On such a cold day, Du Jianhe was only wearing a dirty short coat that he couldn't see what color it was, but bursts of hot sweat were still rolling down, the clothes behind him were already soaked, but his chest was still roasted dry. His face was covered with ash, and he looked like a black man, except for the whites of his eyes. With such a touch of sweat, his forehead was black again.

But he couldn't take care of it anymore, and the guy was laughing with what he was holding in his hand. It's finally built! It didn't take twenty days, it only took seventeen days, and I completed the task assigned by the adults ahead of schedule!

It is a person who is self-motivated, not to mention that Du Jianhe's utilitarian mind is stronger than others, and it is not a bad thing to have a strong utilitarian heart, on the contrary, if Shangguan is properly deployed, it will become a good thing. For example, Dong Ce is Du Jianhe's direct superior, if he likes to flatter and don't do things, then a utilitarian person like Du Jianhe will naturally do what he likes and slip around all day long. But Dong Ce is a person who pays attention to doing practical things, everything depends on the work in hand, and it all depends on your efficiency and ability, so Du Jianhe can become harder than anyone else.

Gaina dreamed of becoming a human being.

What he was holding in his hand now was a barrel, a double-layered barrel that had been completely built and had been built into a dense gun.

The shape and structure of the whole Lumi gun is composed of a gun tube, a gun bed, a curved buttstock, a dragon head and a trigger, a fire gate, a rail, a front mouth, a rear door, and an aiming device called Zhaomen and Zhaoxing.

The most difficult thing to build, which is equivalent to a technical difficulty as later generations, is the gun. Its barrel is cylindrical, rolled with refined steel sheets, and fitted by two large and small tubes, "four feet five or six inches long, about four or five catties in weight, the longer the better, the back of the door, the front of the star, the fire door on the side, under two or three iron buttons, so that the next nail, when put without vibration."

The iron required for the barrel is the finest fine iron, which is actually equivalent to steel.

And now the best iron that Dong Ce can provide is only the wrought iron sent by Bai Tianfu, this kind of steel needs to use ten catties of wrought iron to smelt one catty, in fact, it is cold forging, the impurities in it are beaten out, and carburizing and other processes are carried out to forge the iron into steel. This is more labor-intensive and time-consuming, and only a gun pipe made of such stainless steel will not explode when fired. The life of the shot can also be maintained for a longer time.

After forging the material, it is even more difficult to cast, and the manufacturing method of this art is extremely complicated, and the Lumi gun is a double-layer barrel, which is described in detail in the Wubei Zhi and the artifact spectrum, and is illustrated. But that illustration only made the Chinese craftsmen see in the clouds, and just the shelf with the inner barrel into the outer barrel involved a lot of geometric techniques, and the shape was very Western.

First, two large and small iron rods are made, each rolled into a long iron sheet and beaten into an iron pipe (made of stainless steel), and then the thin pipe is put into a thick pipe.

The description is a simple mess, but the actual operation is a man's mess, and each step can only be done by professionals, and ordinary blacksmiths don't know that the technology can't be imitated at all. There are many small details that if you don't notice it, you will immediately lose the whole game.

Especially the last casing, which was almost forcibly drilled, and the grinding and manufacturing of the two pipes before was simply not something that could not be done by twenty years of apprenticeship. The mere fabrication of two long iron pipes that could fit tightly together would make all the blacksmiths in the world despair, unless there was a master who could make them.

And there's a lot of tricks in it. The barrel must start from the root and reach a thickness of one foot two or three inches to be generally uniform, so as to be appropriate. Guy is angry from here, and he is fixed here, and he naturally goes straight forward, without the danger of exploding. If it is unstable here, then the consequences are difficult to say.

When drilling the barrel, the drill bit is also particular. The drill bit should be five inches long, the top one inch is slightly sharp, and the middle four inches must be evenly rounded and the size is average, and the barrel is straight after drilling. If the drill bit is the same as the jujube core, it will bend down with the bend when drilling, and the inside of the barrel must be crooked and slanted, and it will not be even and upright. The elements that determine the hit rate of the Lumi gun, although the most intuitive manifestation is the role of the door and the star, but if the inside of the gun barrel is not straight, then the fire rope is lit, and after the lead bullet is issued, you are aiming again, and the lead bullet is also rushing left and right, and the hit rate is needless to say. Even a veteran soldier can't guarantee a hit.

The best cylinder is cold forging, if you have to skillfully blacksmith to beat the barrel, such as the chamber content of three money lead, will be two money five points to take advantage of the red to pass, the eight edges are extremely straight, and then with a hammer densely forged, boiling water test no leakage, with a round diamond slightly swept, the chamber is clean, the outside is not rusty. If the barrel is used for a long time, the eye of the fire door will be sprayed with medicinal gas. The big one is not only discouraged, but also kills the forward firepower, but also fears that it will explode from the eye, and it is necessary to immediately remove the root seven or eight inches, and reconnect a section.

The material of the barrel is made, and Du Jianhe can hand it over to others to do, but the next series of technical work such as rolling steel sheets, rolling pipes, and drilling pipes, no one in the entire blacksmith workshop will do it except him.

He can only do it himself.

Normally, the official craftsman can drill about an inch a day, but now Du Jianhe is working for his own future, and this enthusiasm is naturally different. He lived almost exclusively in the workshop, and he brought lunch to him, and every day he only went back to sleep at night when it was fast, and slept for two hours, and the next day he got up and took a few mouthfuls of food, and then hurried to the workshop to continue his work.

In the past ten days, he has been boiled to the point that his eyes are red, like an old rabbit. My body was messy and dirty, I don't know how long I hadn't taken a shower and washed my face, and the new clothes I had issued after coming to Rock Fort had become tattered again, and I don't know how many small holes I had been burned by Mars.

The three major hardships in life, supporting the boat to grind iron and grinding tofu, this iron beating is naturally a physical work. Du Jianhe, who was already thin, now looks even thinner, and there doesn't seem to be two taels of meat on his body. He laughed twice, and suddenly his eyes were a little black, and his body couldn't help shaking, and the barrel he was holding in his hand almost didn't fall. A blacksmith in his twenties next to him hurriedly dropped the hammer in his hand and helped him: "Brother Du, are you okay?" ”
