"Found something! Is it tin or copper! Yang Zilu looked at Gong Ion and couldn't help but ask excitedly.

"The villain palace has seen the chief!" When Gong Ion saw Yang Zilu, he immediately got out of his crazy state and hurriedly said respectfully. There is no way, he is now a slave, or Yang Zilu's slave, which angered Yang Zilu, he decided that he couldn't eat and walked around, you didn't see it, the leather armor craftsman used to be miserable, and the matter of stabbing a sword in vain, Gong Ion didn't want to encounter it.

Yang Zilu didn't care so much, and snatched the ore in Gong Ion's hand with one hand. However, Yang Zilu couldn't see anything special about this stone, this stone was long and gray-white, no different from ordinary stones.

"What kind of ore is this?" Yang Zilu asked, it doesn't look like copper, although it doesn't look like tin, but if you want to say that it is tin ore or copper ore, Yang Zilu thinks that this should be tin ore, right? It is somewhat similar in color to tin ore.

"It's iron!" Gong Ion snatched the ore from Yang Zilu's hand and said excitedly.

"What did you say!" Yang Zilu grabbed Gong Ion's clothes.

was so frightened that Gong Ion's heart and liver almost jumped out of his throat, and he also said that Yang Zilu thought that he had fooled him, after all, Yang Zilu had asked Gong Ion to find copper ore and tin ore before, but he found an unknown ore and came back. At least as far as Gong Ion knows, there are not many people who know iron ore now, but not many, even some big nobles don't know what iron is, Gong Ion is now most afraid that Yang Zilu will misunderstand him for dinner, and he will take a stone back to fool him. He hurriedly explained: "Chief, although this iron is not as hard as bronze, it can be used to forge tools such as plows, hoes, and axes. ”

When Yang Zilu heard this, he was a little dumbfounded, when did iron not be as hard as bronze? However, Yang Zilu suddenly remembered one thing, the Qin State swept the Six Kingdoms, and it seemed that it was also using bronze PK Iron of the Six Kingdoms, and the result was needless to say. I can't say that in ancient times, this iron was really not as hard as bronze.

However, Yang Zilu really couldn't understand how to say that the density of iron was also above bronze, and it was the kind that was afraid that the bronze would be thrown far away. But fortunately, Yang Zilu knows that this era is different from his own era, as far as punishment is concerned. In this era, there is no such thing as people-oriented, once a crime is to cut off your hands and feet, cut off your nose and cut off the second child, and there is no fixed-term sentence at all, even if it is a life sentence, it is also a life sentence, and you are sold to the official family to be a slave. In addition, the people and horses here don't even ride, but only use them to pull carts. But Yang Zilu still spit out his own questions: "How is it possible?" Iron should be harder than bronze! ”

Hearing this, Gong Ion broke free of Yang Zilu's grasp, and said with a light in his eyes: "Chief, you think so too, and I think so too, but they all say I'm stupid!" After my research, this iron is not as hard as bronze, because there are bubbles in it, and there are a lot of impurities and bubbles. However, I learned the method of iron control from the state of Chu, and after constant beating, I can expel impurities and bubbles. ”

Gong Ion was thinking about how to think about Yang Zilu asking for tools and 'funds', and she was even more afraid that Yang Zilu would not know the role of this iron if she had 'eyes but no beads'. But when I met Yang Zilu, a fellow practitioner, his eyes were as if he had been abstinent for twenty or thirty years, and he had just been released, and he just happened to see the eyes of a **naked beauty who was splitting her thighs. Yang Zilu had some heart palpitations.

"What for!" Yang Zilu couldn't help but take a step back, he now thought that this palace ion wouldn't be someone who liked Lala, right? It is said that it was normal for Lala in ancient times, and great men such as Emperor Wu of the Han Dynasty and Alexander the Great were all representative figures of Lala, and they were not far from Yang Zilu's time. As the saying goes, if something is good at the top, it will be very bad at the bottom. At this time, the wind of lala has already risen, and it may not be said.

Fortunately, the timing of Gong Ion's opening was fast enough, otherwise if she continued to watch like this, Yang Zilu said that she would cut Gong Ion and even sew the chrysanthemum, who knows if this girl will play backwards. "Chief, I want a hammer! A big tongs and a lot of charcoal! Pliers, you know? It's used to clip things! ”

Yang Zilu breathed a sigh of relief when she heard this, fortunately this girl was not Lala, otherwise she wouldn't know what to do with him. This is the only swordsmith in the Nine Kui Division, but I think of what Gong Ion wants. Yang Zilu was distressed again, thought for a while, and said helplessly: "There are a few hammers, but these are relatively small!" But when it comes to pliers, I do know, but there don't seem to be pliers in Yueguo! I have to find someone to build it, but now that the snow is covering the mountain, where do you ask me to find someone to build it for you? ”

Hearing this, Gong Ion's eyes widened, and he said, "Chief, don't you look down on me?" ”

When Yang Zilu heard this, he was stunned at first, and then couldn't help but laugh dumbly, and then he remembered that he didn't have a swordsmith here? I also need to find someone else to build it,

Gong Ion is still a anxious surname, he does what he says, and he is ready to directly snatch the sword on Yang Zilu's waist and melt it directly. Of course, Yang Zilu didn't let Gong Ion succeed, anyway, in the battle with the alliance of the two clans, Yang Zilu captured a lot of weapons, and there were many damages. If Yang Zilu hadn't rushed to find the copper and tin mines, he would have asked Gong Ion to reforge these weapons.

Yang Zilu found a passerby and asked him to take his token to the warehouse to get a weapon. Speaking of tokens, this was created by Yang Zilu himself, and I don't know how the passerby conveyed the news, many people came over and said that they wanted to see how to forge a sword.

Yang Zilu looked outside, there were more than 30 people densely packed, but Gong Ion deserved to have the demeanor of a master, and he was not affected by the outside world at all, so he did whatever he had to do. Yang Zilu took a look at it and found that the ancients were really smart, and they would use pottery to make molds, and pour liquefied bronze into them to wait for cooling.

Yang Zilu was also curious before how Gong Ion built weapons. It turns out that it is all cast now.

It was only in the evening that the pliers were made, and the pliers were held in place by a small copper rod cast from pure copper. Yang Zilu also wondered how Gong Ion fixed the two pliers with this small copper rod without screws. Gong Ion directly inserted the small copper rod into the small round hole deliberately left by the pliers, and then flattened the two ends, Yang Zilu couldn't help blinking after looking at it, and couldn't imagine that this could also be done.

Yang Zilu had to put away a bit of arrogance in his heart, and at this moment he also understood that modern people are definitely not much better than the ancients in wisdom in addition to knowledge. But now it's night, and the people who came to see the excitement have dispersed.

But Gong Ion was still in good spirits, and he was ready to make a handful of iron products overnight.

Yang Zilu immediately stopped Gong Ion, Gong Ion looked at Yang Zilu suspiciously, and asked, "Chief, is there any problem?" ”

Although he was asking, he was a little contemptuous, after all, this was his domain, and he had the right to despise others. Yang Zilu naturally didn't care about this small issue, and pointed to the house inside to Gong Ion and said, "Don't strike iron today!" Go inside, and I'll discuss something with you! ”

Gong Ion blinked suspiciously, but still nodded, where Gong Ion and the miner Jin Ping lived, Jin Ping saw Yang Zilu come in, his face changed slightly, and he hurriedly picked up the copper kettle on the fire on the side, and poured a cup of warm water for Yang Zilu.

Yang Zilu nodded to Jin Ping, expressed his gratitude slightly, and then looked at Gong Ion and said: "Gong Ion, you just said that there are impurities in the iron and you have to beat it, but I think there is another way to discharge more impurities!" ”

"Oh?" When Gong Ion heard this, although he didn't believe that Yang Zilu, a layman, had any good ideas, he still inevitably felt a little curiosity in his heart.

"Have you ever heard of steel?" Yang Zilu asked.

"Where did the steel come from?" When Gong Ion heard this, he was stunned, imitated Yang Zilu's accent, and asked suspiciously.

"Steel is a sublimation of iron, made by fusing pig iron and wrought iron in a certain proportion!" When Yang Zilu heard this, he really asked Gong Ion, and after thinking about it for a long time, he found this information in his mind.

"Iron is also raw and cooked?" Gong Ion didn't believe it a little, but he believed it a little.

"Well, I don't know how pig iron and wrought iron came from, but I know that pig iron is harder than wrought iron, but brittle. Wrought iron, on the other hand, is much more than wrought iron, but he is tough, not easy to break, and can be drawn into silk threads. Yang Zilu racked her brains to find these materials from memory. Now Yang Zilu regrets not studying hard in school, and he really hates books when they are used.

"Then according to what you said, Chief, everything I have seen and built before should be pig iron. So how did wrought iron come from? Isn't it like a crop, buried in the ground after a year? Gong Ion asked suspiciously.

When Yang Zilu heard this, he was sweating profusely on his forehead, no wonder many people said that scientists have quirks. It's not that they have quirks, it's that they're too open-minded. Although Yang Zilu didn't know where wrought iron came from, he was sure that according to the method of Gong Ion, what he got after a year was nothing more than a pile of rust. So Yang Zilu shook his head affirmatively and said: "Although I know, it's definitely not this way, let's think about the wrought iron thing later!" ”

Gong Ion nodded, and then thought of the topic that he had diverted away, and now he believed Yang Zilu's words a little. He asked, "Chief, what did you just say about improving the quality of iron?" ”

"Iron-making furnace! And fuel! Yang Zilu said seriously.

"Iron-making furnace? It's a stove, right? Isn't the stove bad now? I feel okay. However, this fuel is really not very good, this black charcoal is really weak, and there is a lot of smoke, it is better to use white charcoal, burn it for a longer time, and there is no smoke! Gong Yi nodded seriously and said.

Yang Zilu was full of black lines when he heard this. Because he knows what white charcoal is, and he also knows how expensive it is. White charcoal is made from elm, birch and other woods, but these woods are still important raw materials for making weapons. Whether it is to make spears, long ge, bow arms, and arrow shafts are all excellent materials. And these woods are still very hard and tough, especially elm, as the saying goes, 'elm lumps do not open', in fact, it is a metaphor for the density of elm, a strong man with a brand new bronze axe to cut down two trees, it will take half an hour, and you have to use a grinding stone to sharpen the axe. Birch is a little better, but it's not much better.

Yang Zilu said that it is impossible to let Gong Ion waste this wood so much, you said that it is enough to burn one or two weapons, and in the future, all white charcoal will be used, and it will not be enough for everyone in the Jiukui Department to go to cut wood.

Yang Zilu ignored Gong Ion's proposal, dipped his fingers in the warm water that was already cold in the teacup, and drew a bonfire on the wooden table. glanced at Gong Ion and said, "This fire is going up, and the hottest is above the fire!" All the time, a wave of hot air is released. You say that if we build an iron-making furnace like this, can we make the hot gas not diffuse, and the temperature will be even higher? ”

Yang Zilu drew the shape of the iron furnace in the strategy game "Fortress" in his memory, and then said: "Is this iron easier to melt?" Wouldn't it become steel if you exercise a few more times? ”

Gong Ion nodded and said, "Chief, you drew this picture well, but I want to ask how this iron is sent in?" Don't send it in to make iron? And how is this molten iron delivered? ”

When he was playing "Fortress", he saw those workers pulling up a few baskets of ore and pouring them down to the top of the iron-making furnace, after a short time, of course, this refers to the game time. The molten iron flowed down from the bottom of the furnace and solidified into a square piece of iron. But how the molten iron flows out, as well as the principle facilities inside, where does Yang Zilu know.

Yang Zilu smiled helplessly at Gong Ion and said with an embarrassed smile: "I knew it was like this, this iron fell to the top, and there was a small opening below, and the molten iron flowed out from here." ”

Gong Ion glanced at Yang Zilu with a puzzled face, and asked, "Chief, is this what you think?" How is this possible? The voice was full of suspicion, obviously secretly accusing Yang Zilu of not knowing how to pretend to understand.

Although Yang Zilu knows that the game is virtual, he knows that "Fortress" is made in imitation of the medieval era, and the processes in it are real, but who knows all the processes.

Yang Zilu said angrily: "There must be nothing wrong with this, but the fuel should be burned with coal, and this iron-making furnace should be divided into two parts!" There is fire underneath this furnace, and above it is an iron pot or something, and when it melts, the molten iron flows out, and impurities remain in it! ”

Speaking of this principle, Yang Zilu also guessed it, and I don't know if it's true.

But he didn't want Gong Ion to hear this, his eyes lit up, and he said, "Wonderful! ”

But immediately, his eyes dimmed, and he shook his head and said, "Impossible! This iron-making furnace could theoretically be built, but what materials did he use to build it? Bronze is definitely not good, it can't stand burning. But I'm afraid I won't be able to use iron a few times, and I'll melt it myself. ”

Jin Ping, who had not spoken on the side, suddenly drew a pattern on the ground and asked Yang Zilu and Gong Ion, "Chief, Gong Ion, what do you think of my iron-making furnace?" ”
