Take the warehouse back to the end of the Ming Dynasty

Zhao Wen looked at the brick kiln built by Wang Liuqi and others, and kept nodding.

Although the brick kiln in front of me is not as good as the brick kilns of later generations, it is much better than those built by Zhou Laoliu and others.

Zhou Laoliu's brick kiln is almost like an unfinished semi-finished product, extremely rough.

"Haha, ginger is still hot." Zhao Wen laughed loudly, patting the wall of the brick kiln in front of him.

Wang Liuqi smiled honestly, looked at Zhou Laoliu whose face was flushed red, and said, "It's just relying on this skill to make a living, how can it not be covered?"

"Okay, don't be modest. Let me ask you, how many bricks can your brick kiln burn at one time?"

"Returning to my lord, it is not a problem to burn 2000 million bricks at one time."

Zhao Wen pinched his beardless chin, pondered for a while, and asked again: "Then let me ask you, how many bricks do you think will be needed to rebuild the entire city wall of Longmen Fort?"

Before Wang Liuqi could speak, Zhou Laoliu hurriedly interjected, "My lord, I know that. My father has repaired this Longmen Castle before, so I know it well."

Zhou Laoliu completely ignored Wang Liuqi's man-eating eyes, and then said: "This Longmen Fort is 50 feet high, [-] feet wide, and has a circumference of about [-] miles. Each brick is two feet long. It is one foot wide and half a foot high. That is to say, the entire section of the city wall needs more than [-] bricks to build."

"I didn't expect this guy to be quite talented in mathematics!" Zhao Wen thought to himself as he looked at Zhou Laoliu, who was spitting all over the place.

"Okay, you guys hurry up and get me another [-] brick kilns first. Hurry up and burn out the bricks for me first. If you don't have enough manpower, go to Zhao Daniu and tell me that I said it. Let him assign some people to you." Zhao Wen paused, then looked at Wang Liuqi, "Come with me."

Zhao Wen walked under a dead tree next to him, and looked at Wang Liuqi who was standing in front of him, hunched over.

"Besides this brick kiln, what else will you build?"

"Back to the adults, the villain can also build the iron-making blast furnace. When I was young, the villain once went to Datong with my father to build the iron-making blast furnace."

Zhao Wen's eyes lit up, and he looked at Wang Liuqi like a baby, "Really? Don't you want to lie to me?"

Zhao Wen hurriedly said, "How dare a young man lie to an adult."

"Then besides these two kinds of stoves, will you build other stoves?" Zhao Wen looked at Wang Liuqi eagerly.

Wang Liuqi replied: "My lord, the young ones can only build these two kinds of stoves. The young ones have only learned how to build these two kinds of stoves. Others, they can't."

Zhao Wen looked at the straightforward and decisive Wang Liuqi, and suddenly had the urge to kick him to death.

You don't know how to cover other things, you were so arrogant just now.Do you see how angry you are with Zhou Laoliu?

"Then do you know how to read drawings?"

"will not!"

"Damn!" Zhao Wen cursed secretly, looking at Wang Liuqi helplessly.

It seems that you built this brick kiln based on experience. I thought you were a person with great ability.Unexpectedly, I was wrong.

"Okay, go and get Zhou Laoliu for me." Zhao Wen waved his hand helplessly.

Seeing Wang Liuqi's leaving back, Li Xiaoying asked, "What is Brother Zhao doing?"

"Oh, cement. I want to build a cement kiln, otherwise, I won't be able to rebuild this Longmen Fort after winter comes." Zhao Wenchang sighed.

After a few breaths, Zhou Laoliu bowed his body and stood in front of Zhao Wen.

"My lord, you are looking for me." Zhou Laoliu bowed his hands to Zhao Wengong with a flattering face.

Looking at Zhou Laoliu's appearance, Zhao Wen said bluntly, "Will you read the drawings?"

"My little one, I'm just not very proficient, but my father is proficient. Unfortunately, my father was killed by the Tartars." When Zhou Lao Liu mentioned his father, his face was full of sadness.

"Okay, don't make a sad face. I will avenge your father in the future. Since you can read the blueprints, I will ask you to build something called a cement kiln according to the blueprints. Can you build it?"

"Yes, as long as it's not too complicated, I can build it. It's just that there may be a little difference." Zhou Lao Liu scratched his head and said awkwardly.

Are you a little different?The brick kiln you built is like a kennel, how dare you say there is a little difference?

Having said that, Zhao Wen can only rely on Zhou Lao Liu now.

Because apart from him, it is estimated that none of these workers can understand the drawings.

"Well, tomorrow morning, I will give you a blueprint, and you must build it for me in the shortest possible time. If you build it well, you will be rewarded a lot." Zhao Wen slapped his thigh, his tone full of Tempted.

"As long as the adults can give me a blueprint, the little one will risk his life to build it for the adults." Zhou Laoliu narrowed his eyes, patted his chest, and shouted plausibly when he heard that he would be rewarded.

"Okay, what I want is your words. Now you go to help Wang Liuqi build a brick kiln. Tomorrow morning, you come to the Garrison Mansion to find me."

As soon as Zhao Wen finished speaking, he left with Li Xiaoying.

Zhao Wen took Li Xiaoying around Longmen Fort a few times, checked the situation on the construction site, and then returned to the garrison mansion.

Zhao Wen sat on the chair, took a sip of the tea Li Xiaoying made for him, leaned on the backrest, closed his eyes and got up.

"Now the brick kiln and cement kiln are done. As long as there is enough time, Longmen Fort can be rebuilt."

Zhao Wen's eyes were slightly closed, and he kept mumbling, with a hint of worry in his tone.

"Is this not good? Brother Zhao, what are you worried about?" Li Xiaoying stood beside Zhao Wen, looking at Zhao Wen with doubts.

Zhao Wen smiled wryly, opened his eyes, and said helplessly, "After the Dragon Gate Fort is built, there must be someone to guard it. Now including you, there are only a few people."

"Brother Zhao can recruit from these workers, I think someone will agree." Li Xiaoying comforted.

Zhao Wen stood up, looked out the door, and said slowly: "There are only a few people, and most of them are old and weak. Apart from these people, I guess there are only two hundred left. What can such a small number of people do? What’s more, there must be people who don’t want to be soldiers.”

"Oh, forget it, what am I thinking about. The castle hasn't been rebuilt yet, so what am I thinking about. Let's take a step at that time."

……

Early the next morning, Zhou Laoliu stood outside the gate of the defense mansion and waited early.

Zhao Wen took the blueprint drawn with charcoal and was about to go to Zhou Laoliu after fighting all night last night, but ran into him as soon as he went out.

It's also fortunate that Zhao Wen didn't return what he had learned to the teacher, otherwise, Zhao Wen would be enough to just have a cement kiln now.

Zhao Wen looked at Zhou Laoliu with surprise, and said, "Why are you here so early?"

"The little one didn't dare to let the adults wait, so he came early." Zhou Laoliu looked at Zhao Wen anxiously, for fear of causing Zhao Wen's dissatisfaction.

"Since you're all here, I'll save my time. This blueprint is what I want you to build. This thing is called a cement kiln, and it needs to be built with refractory bricks. You first use ordinary bricks to build a kiln." Come out, let me take a look first. If it works, use refractory bricks to cover it." Zhao Wen handed the blueprint in his hand to Zhou Laoliu, and said earnestly.

Zhou Laoliu took the blueprint, squinted his eyes and looked at it carefully.

This drawing Zhao Wen has tried his best to make it simpler. On it, there are many details that later generations of engineers can understand at a glance. Zhao Wen also listed it alone, and drew a more clear and clear big picture.

So, Zhou Lao Liu didn't have much trouble looking at the blueprints.

After a long while, Zhou Lao Liu raised his head and said excitedly, "Sir, I will definitely be able to build this thing called a cement kiln. Just wait for my good news."

Zhou Laoliu patted his chest, spit flying, and assured Zhao Wen.

"Okay, then go quickly. Oh, by the way, bring me Wang Liuqi at the same time, I have something to do with him."

Zhao Wen went to Wang Liuqi for nothing but the refractory bricks.

Although this Wang Liuqi felt a bit half-hearted, but after all, this person had burned bricks for half his life. It is estimated that it should be much easier to find him for the matter of refractory bricks.

Although this cement is good, it is not easy to fire.First of all, the firing of cement requires a temperature of at least [-].And the blue bricks of this era simply cannot withstand such a high temperature.

If there is no refractory brick, then everything is in vain.

Chapter 48 Firing Refractory Bricks

Zhao Wen was wandering around the courtyard of the Garrison Mansion when he suddenly saw Wang Liuqi rushing in.

"My lord, are you looking for me?" Wang Liuqi bowed respectfully to Zhao Wen, and looked at Zhao Wen anxiously.

After Zhou Lao Liu was called away by the adults yesterday, his face was full of arrogance, and he put on a face in front of him all day long, so arrogant that he didn't even know his last name.

Today, the lord came to me, it seems that he has something to do with me, if I can do what the lord ordered well today, I will be appreciated by the lord.When the time comes, I'll see if that boy Zhou Laoliu dares to show his face in front of me.

Zhao Wen looked at Wang Liuqi and said in a deep voice, "Do you know about refractory bricks?"

"Firebricks? Bricks that can withstand fire?"

"Yeah, I just don't know if you can fire it?" Zhao Wen asked in a low voice.

Wang Liuqi thought for a while, and then said, "I used to burn bricks for ironmaking blast furnaces, but I don't know if the bricks for ironmaking blast furnaces can work?"

"Bricks on the iron furnace? Hey, I'm afraid this won't work." Zhao Wen shook his head.

The maximum temperature that the ancient ironmaking blast furnace could reach was only over 100 degrees, which is far from the 400 degrees required for firing cement.

"I was thinking, since you have been burning bricks for most of your life, then I was thinking, see if you can make refractory bricks." Zhao Wen said in a deep voice with his hands behind his back.

Wang Liuqi stroked the beard on his chin and said, "But the villain doesn't know what this refractory brick is, so he can't burn it at all."

Zhao Wen looked at Wang Liuqi's anxious face, and said with a smile, "What are you afraid of? If I let you make refractory bricks, then I must have the formula and firing method."

Refractory bricks are referred to as firebricks.Refractory materials made of refractory clay or other refractory raw materials.It is mainly pale yellow or brownish in color.It is mainly used for building smelting furnaces, porcelain kilns and glass kilns, etc.

In fact, in ancient times, there were also refractory bricks, but the production method of this kind of refractory bricks is a secret that few outsiders know.

Moreover, this high-quality refractory brick is basically only available in the south.After all, there are more ironmaking furnaces and porcelain kilns there.In the north, basically few people can burn high-quality refractory bricks.

The refractory bricks used in ironmaking furnaces in the north are far less than those in the south.This is why at the end of the Ming Dynasty, the quality of Sugang was the best at that time.

At the same time, although this high-quality refractory brick is a very good thing compared to this era, it is far from meeting Zhao Wen's requirements.These refractory bricks can basically only withstand a high temperature of more than 100 degrees, which is far from the more than 400 degrees required for cement kilns.

The refractory bricks fired by Zhao Wenrang and Wang Liuqi are a kind of refractory bricks called refractory clay bricks, which can withstand high temperatures of 1580°C-1770°C.

Among various refractory bricks, only refractory clay bricks are the most convenient to fire, and the required materials are also the simplest.

The main material of refractory clay bricks is refractory clay, and this refractory clay is what people often call kaolin, that is, Guanyin clay.

Kaolin is the most common material needed to make ceramics, but it is not an uncommon material.

According to the ability of this era, only refractory clay bricks can be fired.

Refractory clay bricks are easy to fire, and ordinary brick kilns can also be fired, and the materials are also very convenient, so Zhao Wen planned to ask Wang Liuqi to fire refractory clay bricks from the beginning.

"Do you know kaolin?" Zhao Wen looked at Wang Liuqi with a smile on his face.

Wang Liuqi answered, "I know, it's something made of ceramics. But does it have anything to do with this refractory brick?"

"What does it matter? Hehe, there is a lot to do here. Let me tell you, this refractory brick..."

Zhao Wen picked up a branch and squatted on the ground to write and draw. Wang Liuqi stood aside, looking at the strange characters on the ground with a blank face.

Zhao Wen wrote and painted on the ground, and even Li Xiaoying, a scholarly lady like Li Xiaoying, didn't know him.What's more, what about Wang Liuqi who doesn't know a single word?

Zhao Wen looked at the bewildered Wang Liuqi, sighed helplessly, and then introduced to Wang Liuqi in detail the firing method of refractory bricks in a simpler way.

An hour later, Zhao Wen swallowed a mouthful of saliva, moistened his extremely dry throat, then looked at Wang Liuqi, and asked in a hoarse voice, "Do you understand now?"

Wang Liuqi scratched his head, half understanding, and said: "Listen to what your lord said, the firing method of this refractory brick is similar to that of ordinary bricks, except that the soil used is different."

Zhao Wen slapped his thigh, coughed twice, cleared his throat, and said with a happy face: "It's not wasted effort, you're right. In general, the firing method is similar, only a few details and necessary The soil is different."

"Well, you go to build the brick kiln first, and I will go back and draw the detailed method of firing refractory bricks. At that time, you just need to follow the order I drew, and you will be right." Zhao Wen clapped his hands, Brushing off the dust from his hands, he waved at Wang Liuqi.

"Retire, little one!" Wang Liuqi cupped his hands at Zhao Wengong respectfully, then stepped back and left.

Zhao Wen returned to the hall of the Garrison Mansion, picked up the teacup on the table, and drank it down in one gulp.

"Oh, this is exhausting me. It's so hard to tell these people something."

Zhao Wen sat on a chair with a look of lovelessness on his face.

Li Xiaoying stood beside Zhao Wen, and said softly: "What's wrong with Brother Zhao? What's wrong with you?"

"Oh, don't mention it. These people can't read a single word. Telling them something is like playing the piano to the cow. It's just too uncomfortable. I think, from now on, we must find someone who can count as a writer, otherwise, we must I can't be exhausted."

……

Early the next morning, Zhao Wen handed over the drawn drawings to Wang Liuqi, and took Li Xiaoying around the city by himself.

"Come on, one or two. Help me, one or two..."

Zhao Daniu was shirtless, standing on a broken wall, directing the migrant workers to lift a big stone on the ground.

"Daniu, how are you doing?" Zhao Wen saw Zhao Daniu's arm reflecting the light in the sun from afar.

Seeing Zhao Wen coming slowly, Zhao Daniu hurriedly jumped off the broken wall, and said to Zhao Wen with a happy face: "My lord, I am responsible for cleaning up the south side of the fort. The cleaning is about to be completed now, and it will take another two days. , we will be able to clean up this Fort South completely.”

"Haha, not bad, not bad, it seems that your speed is quite fast. How is Song Hu's cleaning up?" Zhao Wen patted Zhao Daniu's shoulder and praised with a happy face.

"They're almost done cleaning it up, and it's only been a few days." Zhao Daniu didn't look happy because of Zhao Wen's praise, but frowned and looked at Zhao Wen.
