"Qi Ye, I said, why are you leaving again? Let's build a house with bricks and tiles. He will grab it for 5 yuan a brick. Let's not buy his bricks. How about we burn them ourselves? Besides, there is Uncle Dazhu This expert is here, what are you afraid of?"

Li Feng was indeed taken aback by the price of this brick, and he didn't recover for a long time.You know, in that era, a brick cost about 3 cents.In these years, a brick costs 5 Wen, and a stone of grain is exchanged for twenty or so bricks.At this time, Li Feng also remembered that firing bricks is not complicated in the first place. If you don’t buy them, you can burn them yourself.

Although Li Feng didn't know how the blue brick was made, he still knew something about the red brick.It is not complicated to fire.

"Hey, I said you boy, why are you so stubborn. You think that burning bricks is as simple as burning lime. The charcoal consumed alone can be piled up into mountains. Moreover, it is necessary to burn the bricks used to build houses in the village. Yes, with so many bricks, I don’t know how long it will take to get them. Forget it, old man today, I’ll tell you how to get the bricks. In case you are still in a feverish way, thinking wildly.”

Hearing that Li Feng still didn't give up, Qi Ye could only sit down and talk to Li Feng about how the brick was fired.

However, after Li Feng listened to Qi Ye's words, he finally understood why this green brick was so expensive.The main reason is that this thing is fired with charcoal.

This thing is not like burnt lime, and the temperature requirement for burnt lime is not high.Therefore, it is done directly with a large fire of wood.Furthermore, this thing can't be like burning lime, everyone can use a small fire, it doesn't matter if it is cold or hot.That would crack the bricks.Therefore, in this era, charcoal is used to burn green bricks.

There is another one, the craft of burning blue bricks.It is much more complicated than burning red bricks.In the end, it was necessary to release water and rely on water vapor to cool.Instead of cooling naturally like red bricks.As a result, the output of blue bricks in each kiln is very low.

The cost is high and the process is complicated.The low production capacity makes the price of blue bricks so scary.

"Hehe, it's okay, Seventh Master, I have a solution. I have a method of firing bricks here, which can be fired in large quantities. Bricks with a very low cost. But, it's not blue bricks. It's red bricks."

The firing process of red bricks is much simpler than that of blue bricks.In the village, Zhao Dazhu is also an expert in this field.Therefore, Li Feng is [-]% confident that he can get the red brick out.

"Red bricks? I haven't heard of this one. Well, what did you say. Can you burn another kind of brick? Besides, the cost is much lower than that of blue bricks. I heard it right. By the way, can you tell me, this The so-called red bricks are as strong as the blue bricks, and how much does it cost to burn a red brick?"

Qiye was taken aback at first, with a look of disbelief on his face.If someone else said such a thing, the old man would definitely ignore it.However, when these words came out of Li Feng's mouth, it was different.For Li Feng, Qi Ye has a deep understanding of the endless new ideas and new gadgets.

Soon, Qi Ye's expression became even more excited.If it is possible to burn bricks that are almost as strong as blue bricks, and the cost is still very low, then this will be a big deal.As for the large batch that Li Feng mentioned, Master Qi ignored it.A small batch is enough for his old man to be happy.

"Well, well, we won't know until we get it out. But, I think, even if it's worse than the blue brick, it's definitely not much worse. As for the cost, it's definitely much lower than the blue brick. But , before that, we need to get something very important."

When Li Feng heard this, he was really hard to say, and he had never compared blue bricks with red bricks.Besides, although bricks can be fired, the quality of the fired bricks can also be different due to different soil properties, different proportions of raw materials, and temperature.Only after burning it out and experimenting can we know.

"Okay, okay, tell me quickly, if you need something, see me, old man, do you know?"

When Qi Ye heard that there was indeed a door, he was overjoyed immediately, and then began to urge Li Feng to see what he needed to find.

"Well, I don't know Qiye, have you heard of coal."

When Li Feng heard it, yes, this old man is well-informed, so he told Qi Ye what he was looking for.Isn't it silly to use charcoal to burn bricks?That's not burning bricks at all, it's burning money.If coal is found, it will be easy to handle.

Li Feng thought to himself, the location of Chang'an is Shaanxi, which is also a top-ranked coal-producing province in China, so it shouldn't be difficult to find some coal.Besides, if you go to Shaanxi, isn't that Shanxi?Believe it or not, there will be no coal.

"Coal? What kind of charcoal is this? Just tell me, this kind of charcoal is made from something."

When Qi Ye heard about coal, he had never heard of such charcoal.So, he opened his mouth and asked Li Feng, as long as he knew what was used to burn it, it would be fine.

"This kind of charcoal is made of... look at me, I'm dizzy, coal doesn't need to be fired"

Li Feng was thinking about a question, when he suddenly heard Qi Ye ask, what is the coal used to burn, he thought of answering reflexively.But, thinking about it, this is not right.This coal is dug directly from the ground and is used for burning, but it is not burned with anything.

"Then it doesn't need to be fired, so why is it called charcoal?"

When Qi Ye heard this, he became even more anxious, how could there be such charcoal.Charcoal is made from trees, so why is the coal not burned with other things? Can it still be called charcoal?

"Why charcoal must be... Forget it, Qi Ye, let's not care what it is called now. Let me tell you this, this kind of thing is black, which looks similar to charcoal in color, but it is It was dug out from the ground. Another feature is that this thing can also be ignited like charcoal."

Only then did Li Feng come to his senses, this coal is called in modern times, who knows what it was called in ancient times.He and Qi Ye have been entangled in this name all day long, isn't he just looking for boredom?So, he began to describe it to Master Qi in detail.

"I said you child, you just say, you can find graphite. Is it, when it burns, it still has a very unpleasant smell, the kind that is very choking."

"Yes, that's right, Qiye, do you know where this thing is available nearby? Or where it is sold, is it expensive?"

When Li Feng heard it, the seventh master really knew about the coal, so he immediately asked excitedly.However, what makes Li Feng feel strange is that this coal is called graphite.Isn't graphite a different thing.However, now, Li Feng doesn't care about these, all he wants to know is the price of this coal, or where to find it nearby.

"What's the use of this thing? It's used to make a fire for cooking, and the fire is no better than wood. It's very choking, unbearable, and it's not as good as charcoal. People in the city basically don't know how to use it. And In the countryside, who would use that? There is no good firewood at all. Therefore, if you want to buy it, it is really hard to find. As for the old man, I don’t know if there is one nearby. Who cares about such useless things ah."

"I said little lunatic, you don't mean that you want to buy this coal?"

When Qi Ye heard this, he thought to himself, who would use this thing.However, soon, he came back to his senses.Li Feng just asked where to sell this thing.

"It's not sold, it's not easy to handle. However, since people seldom use this thing at this time, it must be a bad and cheap thing. No, I have to find a coal mine. Without it, I want to burn If you want to build a house with bricks, isn’t that a fool’s dream. But how to find it and where to find it. Moreover, it can’t be too far away, otherwise, if you use a horse-drawn cart these days, the shipping cost will be scary.”

"Hehe, yes, I'm going to look for the second child. I can't find it. Could it be that he can't find it? Yes, that's the way to do it."

The news Qiye provided to Li Feng both made Li Feng happy and depressed him at the same time.This thing must be found, but the traffic restrictions these days have restricted many things to death.Just like the last time, when he asked others to help him bring rice seeds back from Champa, the price soared hundreds of times.Among them, of course it is because the amount he wants is relatively small.However, the most important thing is that it is difficult for others to transport.

However, Li Feng himself can't help it, but Li Shimin can't help it.

"Qi Ye, you have to wait and go back slowly. I'll take a step first and go to Chang'an City."

Thinking of this, Li Feng immediately turned around and ran, speaking loudly to Master Qi while running.

"Hey, I said you bastard, what are you doing in Chang'an City when you have nothing to do? You haven't explained the matter here clearly, how should you deal with it. Hehe... This little bastard also said that I am an old man, and I am in a hurry , I am not the same, running faster than a rabbit. However, that graphite, oh no, is that coal really that easy to use? But it is not right, I have seen that thing with my own eyes... ..”

Qi Ye saw that Li Feng had run away, so he immediately shouted loudly behind him.It's a pity that Li Feng had already gone far away, and after a few strokes, he couldn't even see his back.Immediately, Qi Ye was really depressed, but what made him even more curious was this Shi Mo.

Running home like the wind, Li Feng first explained to Rou Niang and the others, and then he was ready to go out.

Because there was only one person, and because he was in a hurry, Li Feng did not use a carriage, but directly rode on a horse, and left the village in the direction of Chang'an City.
