The leader has always been very busy, and he left after giving orders.

After Yang Jianping habitually finished watching, he began to walk around this long steel plate room.

As an honorable working class, if you want a better job, familiarizing yourself with the place of work is the first priority.

There are a lot of machines here, placed a few meters apart one by one, divided into two rows, neatly and neatly, and the machines have names on them, so to speak, the large-scale production equipment in the underground equipment warehouse is here.

In addition, there are some auxiliary small production tools, such as polishing machines, drilling machines, grinding machines, cutting machines, measuring instruments...... And so on, all of which are placed on a specially made wooden shelf, and they are neatly arranged.

It is easy to surmise that these young people in the production department have been working hard for a while before they came.

Yes, they are all young people, unlike Yang Jianping, who is in his fifties and looks old, most of the other busy young people in the house are in their twenties, most of them are men, and there are only two or three women, all of whom exude an enviable youthful atmosphere.

These young people are not doing their own thing, but they are gathered in groups of three or five, standing in front of a certain piece of equipment and busy, from time to time making all kinds of surprises, praises, ridicule, and questions, which sound full of vitality and full of young people's unique energy.

Of course, many of them cast curious glances at Yang Jianping, but for some reason, no one came up to say hello.

After walking around this "production factory", Yang Jianping walked in front of one of the larger crowds.

There were almost eight people in this group, seven young men, surrounded by a beautiful young woman with long hair, and in front of them was a [3D metal printer].

I saw that the long-haired young woman was holding a long sword that was more than half a human long, with a complex shape and a cold light, and was trying to lift it.

Next to her, the seven young men were discussing passionately:

"This frost sorrow is so real!"

"Look at this pattern, this line, it's formed in one piece, it's not too good."

"This machine is really easy to use, and it can cut such a thick metal ingot with a few brushes."

"It's still Atan's craftsmanship is good, and such complex details can be recalled, so I can't do it, I can only think of a framework in general."

"By the way, the runes on this sword are not going to be dyed, I remember it's blue."

"This paint is not good, how can it be said in the textbook...... It seems that it is necessary to consider the adhesion of metals......"

"Don't care if you dye it or not, let's make a few more handfuls and use them for the front-line team members, the boss of Tiangong has urged it several times."

……

What's the situation? Are they going to take such a handful of bells and whistles to fight monsters? This is nonsense!

Seeing that they were going to put another long piece of metal ingot into the machine, Yang Jianping didn't care about anything else, took two steps forward, and came to them: "Wait a minute! ”

"Huh? So that's it? "Someone turned back.

"Oh, you're the gunsmith that Brother Kaiwu paid a lot of money for, right?" Someone knows the goods.

"What's the matter with you? Do you want to use a machine? "Some people are puzzled.

"It's not!" Yang Jianping shook his head: "Let me ask, do you plan to give this weapon to other guild members?" ”

"yes, what's wrong?" Someone wondered, "What's wrong?" ”

"Of course not!" Yang Jianping was angry at his misfortune: "How can this kind of thing be used in battle? It's a burden! ”

"Why?" It was the only young woman who spoke: "This sword is still very sharp." ”

"Hey......" Yang Jianping sighed, lamenting it: "It's not a question of sharpness or not!" How much does such a big sword have to weigh? You have a hard time lifting it, even if you give it to a man, how many times can he swing it? ”

"And, what's going on with the shape of this sword? Why are there so many bells and whistles on it? And deliberately make a relief carving, does it make sense? Don't you know how to save materials? With such a large chunk of raw materials, if you build a long knife, you can fight at least three! ”

"Also, the luster of this sword is not quite right, what raw materials are you using?"

Shocked by his long list of criticisms, a group of people did not speak for a long time, and after a long while, they were humane: "Use iron, otherwise what to use?" ”

"Hey, okay." Although he was sighing, Yang Jianping's spirit was very good, as if he had returned to the time when he took his apprentices in the factory more than ten years ago.

He explained in detail: "Making metal utensils is different from making other things, metal utensils basically do not use a simple metal material, most of them are alloys!" What you want to build now is a sword-like melee weapon, which requires a certain hardness and toughness guarantee, and if you use pure iron, it will be very brittle and very easy to break during actual use! ”

"So what should I use?" Someone raised his hand to ask questions.

"High manganese steel, of course!" Yang Jianping began to impart experience: "I've seen the gangster movies in Hong Kong and Taiwan, the gangsters in it cut people with knives, which are the kind of long watermelon knives, they are made of high manganese steel, sharp and tough, and very easy to use." ”

"Then how to match this high manganese steel?" Someone is diligent and inquisitive.

"This is simple, the so-called high manganese steel, that is, the manganese metal content is more than 10%, less than 15% of the steel, of course, its carbon content is also very high, around 1%." Yang Jianping continued to teach: "Do you have elemental manganese metal here? ”

"Oh, yes, yes." Immediately someone shouted, and then ran out like the wind.

After a while, he brought a small piece of boxy metal with the word "manganese" printed on it.

"Hmm." Yang Jianping nodded, and said like an apprentice more than ten years ago: "Bring a few more iron ingots and follow me." ”

After a while, the group came to the [Alloy Decomposition and Reconstruction Machine] that Yang Jianping was familiar with before and had read the manual, and put the metal ingots given by everyone into the machine.

Clicked the switch, and under the urging of the plasma battery, a small touch LCD screen on the machine lit up.

Set various parameters on the LCD screen, click OK, and with a "hum", the machine will be running.

In less than a minute, the roar in the machine stopped, the hatch opened, and a large piece of one-meter-long alloy ingots fell into the machine's discharge bin.

Picking up the metal ingot, a group of people returned to the [3D metal printer].

Yang Jianping continued to teach: "To make melee weapons, in fact, it is better to make a sword than a knife, and the use of a knife is far better than a sword...... Well, there's a friend, he's ...... Forget it, forget it, in short, the knife is easy to use, but the weapon is not suitable for being too heavy, at most at most, three catties is almost ......"

Just as Yang Jianping was teaching with his apprentices, the leader who had left before, Batian Tiangong, walked in:

"Everyone, be quiet! The first batch of team members who went out to explore came back, and they also brought back a batch of prey, and now they urgently need a batch of kitchen knives, which are the kind they usually use at home. 2k reading network
