    "Master Qi, why did you leave again? Let's build a brick house. He can grab it for 5 yuan a brick. We don't buy his, let's burn it ourselves, how about it? Besides, Uncle Dazhu is here  The experts are here, so what are you afraid of?"

    Li Feng was really shocked by the price of this brick, and he didn't come back to his senses for a long time.  You know, in that era, a brick cost about 30 cents.  Nowadays, one brick costs 5 yuan, and one stone of grain can be exchanged for about twenty bricks.  At this time, Li Feng also remembered that this brick-making process is not complicated. If you don't want to buy it, you can bake it yourself.

    Although Li Feng didn¡¯t know how the blue brick was made, he still knew something about the red brick.  Firing is not complicated.

    "Hey, kid, why are you so stubborn? Do you think that burning bricks is as easy as burning lime? The charcoal consumed alone can be piled up into mountains. Moreover, it is necessary to burn bricks to build houses in the village.  Yes, there are so many bricks, and I don¡¯t know if I¡¯ll get them until the end of the year. Forget it, old man, I¡¯ll tell you how to get these bricks today, so that you don¡¯t get too hot-headed and have random thoughts.¡±

    Hearing that Li Feng still refused to give up, Master Qi could only sit down and briefly talk to Li Feng about how this brick was fired.

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

    This thing is no better than burnt lime. The temperature requirements for burnt lime are not high. Therefore, just use wood to make a fire and it will be done.  Furthermore, this thing cannot be like burning lime, everyone can also use a small fire.  It doesn't matter if it's hot or cold.  That will cause the bricks to crack and break.  Therefore, in this era, charcoal was used to burn green bricks.

    Another thing is that the process of firing green bricks is much more complicated than firing red bricks.  In the end, we actually needed to put in water and rely on water vapor to cool it down.  Rather than cooling naturally like red bricks.  This way.  The output of green bricks in each kiln is very low.

    The cost is high, the process is complex, and the production capacity is low, which is why the price of green bricks is so scary.

    "Haha, it's okay. Master Qi, I have a way. I have a brick-burning method here, which can be used to bake large quantities of bricks into very cheap bricks. However, it is not blue bricks, but red bricks."

    The firing process of red bricks is much simpler than that of green bricks.  Inside the village.  Zhao Dazhu is also an expert in this field.  Therefore, Li Feng is 100% confident that he can get this red brick out.

    "Red brick? I've never heard of this. Hmm. What did you say, you can bake another kind of brick? And the cost is much lower than that of blue brick. Did I hear you right? By the way. Can you tell me, this  Are the so-called red bricks strong? Also, how much does it cost to bake a red brick?¡±

    Master Qi was stunned at first, with a look of disbelief on his face.  If someone else said such a thing, he would definitely not care.  However, when these words came out of Li Feng's mouth, it was different.  Master Qi is very aware of the endless new ideas and gadgets that come out of Li Feng.

    Soon, Master Qi¡¯s expression became even more excited.  If bricks that are almost as strong as blue bricks can be made at a very low cost, then this will be a great success.  As for the large quantities that Li Feng mentioned, Master Qi simply ignored them.  A small batch is enough to make his old man happy.

    "Well, how about this, I won't know until it's done. However, I think that even if it is worse than the blue brick, it will definitely not be much different. As for the cost, it must be much lower than the blue brick. But  , before that, we have to get something very important first.¡±

    When Li Feng heard this, it was hard for him to say this. He had never compared blue bricks with red bricks.  Besides, although bricks can be fired, the quality of the fired bricks may also be different due to different soil qualities, different proportions of raw materials, temperature and other reasons.  Only after it is burned out and tested can we know.

    "Okay, okay, tell me quickly, what do you need? Look at me, old man, if I know."

    When Master Qi heard that there was indeed a way, he was immediately overjoyed. Then he began to urge Li Feng to see what he needed to find.

    "Well, I don't know, Master Qi, if you have heard of coal."

    When Li Feng heard this, he thought, yes, this old man is very knowledgeable, so he told Master Qi what he was looking for.  Wouldn't it be silly to use charcoal to burn bricks?  That one is not burning bricks, it is burning money.  If we find coal, it will be easy.

    Li Feng thought to himself, Chang'an is located in Shaanxi, and Shaanxi is also the top coal-producing province in the country. It shouldn't be difficult to find some coal.  Besides, if Shaanxi goes up, wouldn¡¯t it be Shanxi?  I still don¡¯t believe it, there will be no coal.

      "Coal? What kind of charcoal is this? Just tell me what this kind of charcoal is made of."

    When Master Qi heard about coal, he had never heard of such charcoal.  So, he asked Li Feng, as long as he knew what it was made of, that would be fine.

    "This kind of charcoal is made of look at me, I'm dizzy. Coal doesn't need anything to make it."

    Li Fenglai was just thinking about the question when he suddenly heard Master Qi ask what the coal was made of, so he thought of an answer reflexively.  But, when I think about it, this isn¡¯t right.  This coal is dug directly from the ground and is used for burning. It is not burned with anything.

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

    When Master Qi heard this, he became even more anxious. How could there be such trouble?  Charcoal is made from trees. How can this coal not be made with anything? Can it still be called charcoal?

    "Why does charcoal have toforget it, Master Qi, let's not care what it is called now. Let me tell you this, this kind of thing is black and looks similar to the color of charcoal, but it comes from  It's dug out of the ground. Another feature is that it can be ignited like charcoal."

    Li Feng finally came to his senses. This is the modern name for coal. Who knows what it was called in ancient times.  He and Qi Ye have been struggling with this name all day long, aren't they asking for trouble?  So, he began to describe it in detail to Master Qi.

    "I'm talking about you kid, just say you are looking for graphite. Isn't it? When it burns, there is a very unpleasant smell, very choking."

    "Yes, that's right, Master Qi, do you know this thing? Is it available somewhere nearby? Or is it sold somewhere? Is it expensive?"

    When Li Feng heard this, he realized that Master Qi really knew about this coal, so he immediately asked excitedly.  However, what makes Li Feng feel strange is why this coal is called graphite.  Isn't graphite something else?  However, Li Feng doesn't care about this now. All he wants to know is the price of the coal or where to find it nearby.

    "What's the use of this thing? When used to make a fire for cooking, the fire is no better than wood. When used to make a fire, it is very choking and unbearable, but it is no better than charcoal. Basically, people in the city don't know how to use it. And.  Who would use that in the countryside? There is no firewood at all. Therefore, if you want to buy it, it is really hard to find it. As for whether it is available nearby, I don¡¯t know who would care about this useless thing.  ah."

    "You little lunatic, you're not saying you want to buy this coal, are you?"

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

    "It's not for sale. This would be difficult. However, since people rarely use this thing at this time, it must be a cheap and cheap thing. No, we have to find a coal mine. Without it, I want to burn  Brick, if you want to build a house, isn¡¯t it just a dream? But how and where to find it? And it can¡¯t be too far away, otherwise, the freight would be terrible in this day and age.¡±

    "Haha, yes, I'm going to find the second child. I can't find him, so why can't he still be found? Yes, that's it."

    The news that Master Qi provided to Li Feng made Li Feng happy and depressed at the same time.  You can definitely find this thing, but the traffic restrictions these days restrict many things.  Just like last time, he asked someone to bring rice seeds back from Champa, and the price soared hundreds of times.  Of course, this is because the amount he wants is relatively small.  But the most important thing is that transportation is difficult.

    ¡°However, Li Feng himself can¡¯t do anything, but can Li Shimin still be helpless?

    "Master Qi, please go back slowly later. I'm leaving first. I want to go to Chang'an City."

    Thinking of this, Li Feng immediately turned around and ran away. While running, he said loudly to Master Qi.

    "Hey, I said you bastard, why are you running to Chang'an City when you have nothing to do? You haven't explained the things here clearly yet, how to do it. Haha This little bastard, he also said that I am an old man who is in a hurry.  I'm not the same, I can run faster than a rabbit. But, that graphite, oh, no, that coal, is it really that useful? I've seen that thing with my own eyes"

    When Master Qi saw that Li Feng had run away, he immediately shouted loudly behind him.  Unfortunately, Li Feng had already run far away, and after a few moments, he couldn't even see his back.  Master Qi was immediately depressed, but what made him even more curious was this graphite.

    Running home like the wind, Li Feng first informed Rou Niang and the others, and then prepared to walk out.

    Because onlyThere was a man, and in order to rush for time, Li Feng did not use the carriage, but directly rode on the horse, left the village, and left in the direction of Chang'an City.
