The pattern drawn by Jin Ping is very simple, like a U-shape, Jin Ping added a line obliquely in the U-shape, Jin Ping opened his mouth and introduced: "Chief, you see, this oblique line is carbon at the bottom, iron ore at the top, and there is an opening under this, the bellows are placed here, and this gas blows here, is this iron melting a lot?" This outside can be piled up with some fire-resistant stones, and if it burns out, it's a big deal to change it to a stone! ”

Yang Zilu's eyes lit up when he heard this, although this was different from what he thought, it was much better than Gong Ion's pure artificial. "How did you come up with that? It's amazing! ”

Jin Ping smiled awkwardly and said, "I just heard the chief say that this fire goes up, and there is an iron-making furnace, I think of the summer dinner." You also know that the weather is already hot, and the rice has just been cooked. And we slaves have a very short time to eat, and we have to go to the mine if we can't finish eating. At that time, we used chopsticks to dig a small hole in the front and back of the rice bowl, and blew it inside, and the heat in the rice was blown away from the small hole on the other side, and the rice naturally became cold. And according to what you said, the chief, this is not blowing hot gas on the ore, is it possible to melt faster, this is what I thought. ”

Hearing this, Gong Ion's eyes lit up and said, "Wonderful, there should be an opening in this other place to let the molten iron flow out of here." Chief, let the furnace be built now! ”

Although Yang Zilu was also excited, he was much calmer than Gong Ion, shook his head and said: "It's useless to build it now, you only have that piece of ore on hand." But Gong Ion, now that it's freezing cold, where are you going to find this ore? Besides, although it is not white outside, it is not easy to mine ore! ”

Hearing this, Gong Ion smiled and said, "Luck! It was snowing outside again at noon today, so I found a cave with Brother Jinping to avoid the snow. I just wanted to find some stones to build a stove, and I found these iron ores! Ha! Ha! Ha! God really helps! ”

When Yang Zilu heard this, he hurriedly asked, "Is this iron ore big?" ”

Gong Ion shook his head blankly and said, "I don't know, you can ask Brother Jinping!" He should know something! ”

Jin Ping didn't wait for Yang Zilu to ask, and hurriedly said: "I think this should be a small iron mine, at most it produces about five or six hundred catties of iron ore. ”

Hearing this, Yang Zilu nodded, then turned his head to look at Gong Ion and asked, "Gong Ion, how much pig iron can be smelted out of these six hundred catties of iron ore?" ”

Gong Ion frowned, thought for a while and said: "The quality of this ore is not bad, six hundred catties, about three hundred catties, but I am afraid that there are a lot of impurities here, and if you beat it again, it can be about two hundred catties!" But all this is unknown, and a little more, maybe a little less, it's hard to say. ”

Jin Ping saw that Yang Zilu was not very happy, and comforted: "Chief, the output of this iron mine has just been excavated, but this is mainly due to the lack of tools, and the hole is not dug deep enough, so there will be no problem in digging deep in the future." ”

Although listening to Jinping's comfort, Yang Zilu's eyelids couldn't help jumping, the weight of the Spring and Autumn Period was different from that of modern times, and it was about two catties to have the weight of one catty in modern times. That is, it is said to produce 100 catties of iron. It's only 3,000 catties a month, and 36,500 catties a year, this output makes Yang Zilu depressed, and it is estimated that a small iron factory can despise Yang Zilu in modern times.

If Zhao Ying knew that Yang Zilu was depressed, I am afraid that he would be even more depressed, when the Jin Kingdom cast the criminal tripod and collected the national folk ironware, he collected 480 catties of iron and came to cast the criminal tripod. You must know that although the Jin Kingdom is in decline, it is still a well-deserved hegemon-level power, and you can have more than 36,000 a year, which is less?

However, Yang Zilu thought of a new question, charcoal is easy to say, but where does coal come from? The only major coal producer Yang Zilu knows of is Shanxi. There is no way, there are countless people who die in Shanxi every year because of coal mine disasters, and you can't pay attention to it. But now Shanxi is the territory of the Jin Kingdom, not to mention that far water can't quench the thirst of the near, even if Yang Zilu relies on the Jin Kingdom, he doesn't dare to fight his idea. The hair plucked out by the Jin Kingdom is thicker than Yang Zilu's waistline.

Yang Zilu sighed helplessly and said, "This iron-making furnace matter, let's do it tomorrow!" Get a good rest, all of you! ”

Yang Zilu didn't wait for Gong Ion to speak to Jin Ping, and left. Leaving the two of them looking at each other, I don't know what happened to Yang Zilu. When I got home, the little fox was already asleep, Yang Zilu didn't want to wake up the little fox, so she went to bed lightly, but she didn't sleep, but leaned on the head of the bed and thought that there was a coal mine in Zhejiang.

Don't really say it, there is nothing difficult in the world, but I am afraid of people with hearts. After a night of hard thinking, I really thought of a way for Yang Zilu, of course, I didn't think of a coal mine in Zhejiang, Yang Zilu didn't know that there was a coal mine in Zhejiang with such a pitiful knowledge. However, Yang Zilu knew that it was useless to think about anything, so it was better to ask others and mobilize the power of the masses.

Early the next morning, everyone noticed a strange thing, that is, the chief asked people everywhere, and there was no black dirt, but this soil could not grow anything, and it could be burned. At the end, I added that it doesn't matter if you can't burn it.

Not to mention, there are really people who know about this, and this coal mine that Yang Zilu thinks about at night is actually on Jiukui Mountain, and it is still an open-pit coal mine, but the exposed area is not very large, and the quality is not very good. Yang Zilu asked people to dig up the snow and took a few pieces of coal to sit on the sample, and found that the coal burned a lot of smoke. However, in terms of temperature, it is a little higher than charcoal. It's a pity that Yang Zilu doesn't know how to refine coke, otherwise it can make the temperature of coal even higher.

At the same time, due to heavy snowfall, the mine had to be delayed until spring. But the iron ore has been mined, and Yang Zilu arranged for Jinping to be in charge of this matter, six slaves are responsible for digging, and ten slaves are responsible for transportation, which is not a small occupation. However, it was only 400 catties of excavation every day, which was much smaller than Jinping expected.

Now Yang Zilu can only hope that Gong Ion will not let himself be short of two pounds or two.
