readx;?“ Ah Lang is talking about charcoal! There is one near Chang'an City. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Zhao Liu has lived in Chang'an City for decades, and he knows the situation around Chang'an City well, and there is basically nothing he doesn't know within a radius of fifty miles.

"Is there near Chang'an City? In what place? ”

Hearing this good news, Li An was naturally very excited, coal is an extremely important strategic resource, in the energy structure of later generations, has always occupied an important position, but Li An has lived in the Tang Dynasty for so many years, but it is rare to see the use of coal in the homes of ordinary people, especially in the homes of nobles, all of which are firewood, at most half-burned charcoal.

Of course, this is mainly because people in this era have not yet realized the great benefits of coal, they are just frightened by the side effects and appearance of coal, so they dare not try it easily, which is also the inherent thinking of people, everything new is always not easy to be recognized, and it takes a long time of practice and proof to be gradually recognized.

Most of the people of the Tang Dynasty did not dare to try to use coal easily, but the next dynasty, the Song Dynasty, began the history of large-scale use of coal.

Li An clearly remembered that in the history books of later generations, there was a record of the large-scale use of coal by the common people in Bianjing, the capital of the Northern Song Dynasty. ’

This shows that through the continuous exploration of a small number of ordinary people, by the time of the Northern Song Dynasty, the common people of China had fully realized the wonders of coal, and began to switch to coal on a large scale, thus greatly promoting the development of handicrafts and improving people's quality of life.

If it weren't for the Jin soldiers' southward march to break all this, the Great Song Dynasty would most likely have further developed the handicraft industry and invented the steam engine hundreds of years earlier than Europe, thus promoting the early arrival of the Industrial Revolution.

History cannot be assumed, but Ang Lee came to the Tang Dynasty inexplicably, and there is a lot of knowledge of later generations in his head, which can at least change history to a certain extent, at least in terms of science and technology, great progress will be made, and the use of coal is the first step.

"Ah Lang, after crossing the small river in front, fifteen miles to the south is the carboniferous mine, where some of the coal is exposed, and some need to dig several feet of ground, and it can be dug within a radius of dozens of miles."

Zhao Liu replied seriously, not only did he know about the carboniferous mine not far away, but he had also been there once, it should be said that he was passing by.

"Fifteen miles south across the river, so close? Who does this coal mine belong to? ”

After clearly knowing the location of the coal mine, Li Anxia was greatly surprised, he did not expect that the nearest coal mine was so close to Chang'an City, and it was even closer to his courtyard, only fifteen miles, which was very convenient for mining and transportation, in addition, he was very concerned about the ownership of this coal mine, because it meant that he could successfully exploit these resources.

"Ah Lang, these charcoal is poisonous, put it in the house to roast the fire, it will poison people, and the charcoal is very dirty, it will make the hands very black when you hold it in your hand, and when the wind blows, it will also blacken people's faces, so there will not be too many people to use it at all, in addition, where there is charcoal, crops and fruit trees cannot grow, it is a waste land, and naturally there will be no belonging, only the poor people, will dig some back to use."

Zhao Liu's face was suspicious, he had already seen that Li An was very interested in charcoal, but these charcoal were not good things, far less clean and safe than firewood.

Li An naturally understands Zhao Liu's thoughts, people in this era don't know enough about coal, and it's normal that they can't accept it, but the coal mine has no ownership, and it is regarded as a dispensable wasteland, this cola spoiled Li An, which is enough to show that this land is not valuable, as long as you spend a small price, you can buy this land.

"Zhao Liu, I want to buy all the carboniferous mines in the south, you can do this matter! In addition, to build a bridge over the creek ahead, it will be five steps wide. ”

Li An immediately made a decision and issued an order to buy the coal mine and build a bridge, after the coal mine was bought, he could mine boldly with confidence, and the construction of a wide bridge was to facilitate the transportation of the distant coal back for his own use.

"Yes, Aaron."

Zhao Liu knew that it was impossible to change what Li An decided, he had no choice but to agree, and through the understanding of these days, Zhao Liu had great trust in Li An, since Li An needed Shi Tan, there must be a reason for needing.

"Zhao Liu, let's go to the location of the coal mine first! Walk. ”

Li An felt that it was safer to investigate it in person, so under the leadership of Zhao Liu, he rode his horse through a small bridge five miles upstream and went straight to the carboniferous mine.

As Ang Lee expected, the quality of the carboniferous ore here is very good, there are a lot of carbons exposed directly in the air, which looks black, and most of the location is covered by a layer of not too thick soil, and the soil is covered by very vigorous weeds, of course, there are also dotted shrubs, which look relatively desolate.

Li An picked up a piece of coal casually, broke it into two parts, and at the moment of breaking, some coal dust splashed on Li An's face, making Li An's face a lot darker, and then looking at the palm, it was even blacker.

"Good coal, really good coal, good, good."

Li An ignored the smudges on his palms and face, and happily handed the coal mine to Zhao Liu.

"Ah Lang, these charcoal blocks are black, and the faces of the people standing next to them are black when the wind blows, what do you want to do in such a mine, our house can afford to burn firewood."

Zhao Liu reluctantly took the two pieces of carboniferous ore, looked at the black palm, and asked curiously.

"Coal is a good thing! It burns much longer than firewood, it saves space, and it burns without sound, quieter than firewood, in short, the good thing is that as for the poisonous gas you mentioned, I have my own way of dealing with it. ”

Li An explained lightly that the benefits of coal are naturally far greater than firewood, and as for the poisoning of people, it is caused by improper use, as long as you know the scientific principle of coal poisoning, you can naturally deal with it.

Riding a horse and galloping on this wasteland, Li An's mood is getting better and better, such a huge coal mine, if it is used with existing scientific and technological means, it will not be mined for hundreds of years, so Li An will no longer have to worry about fuel.

"Zhao Liu, this piece of land must be taken as soon as possible, and the bridge must be built as soon as possible, and it must be a strong stone arch bridge."

Li An excitedly gave the order.

"Yes, Ah Lang, I will do it as soon as possible."

After Li An explained some details, he took a large bag of charcoal he picked up, and rode back to Chang'an City, he wanted to use it first to see what the quality of these charcoal was, and how much higher the combustion efficiency was than firewood, so as to judge its quality.

When he rode back to the mansion, it was already dark, and after handing over the horses to the servants, Ang Lee couldn't wait to take a large bag of charcoal to the bathroom and prepare it for use in the bathroom fireplace.

"Ahh Pander to...... Ah Lang, Cao'er has seen Ah Lang. ”

Looking at Li An, who was black, Cao'er screamed in fright, and only after seeing Li An's face clearly, Cao'er sighed with relief.

"Cao'er, what are you screaming nonsense, is Ah Lang so terrible?"

Li An joked with a smile, put a large bag of charcoal in his hand on the ground, and dusted off his dirty hands.

Cao'er pinched her pink little mouth, looked at Li An curiously, and said with concern: "Ah Lang, what's wrong with your face, why is it black like this, I was really scared to death Cao'er just now, Cao'er thought it was a bold Kunlun slave who broke into the main house?" ”

"Kunlun slave? Is my face so dark? Don't you lie to me? ”

Ang Lee just picked up a large bag of charcoal, as for what his face was dyed, he didn't know very well, but it shouldn't be as exaggerated as the black of Africans!

"Husband, you ...... Your face ......"

Yan Ruyu was reading a book in the room, and when she heard the sound of Li An and Cao'er talking, she hurriedly put down the book and walked to the courtyard, but suddenly found that Li An's handsome face had turned black charcoal, and she was immediately shocked and suspicious.

"Ma'am, is my face really dark?"

Li An suddenly felt that Cao'er might not really be lying, after all, Yan Ruyu's reaction was there.

Yan Ruyu was stunned for a moment, looked at Cao'er, and said softly: "Cao'er, go and get a basin of water." ”

As he spoke, he walked to Ang Lee's side and wiped Ang Lee's face with the silk handkerchief in his hand.

"Alang, ma'am, the water is coming."

Cao'er set up the basin and handed over a towel.

Li An looked at the water in the basin, and immediately became happy, his face was really black, dark and dark, not much better than the few Kunlun slaves he bought.

"Hahaha! I really didn't expect that I picked up a bag of charcoal and smeared my face so black, madam, kiss. ”

"Husband, don't make trouble."

Yan Ruyu stretched out her hand to block Li An, and asked curiously: "Husband, you are good, why did you run to pick up charcoal, there is no shortage of firewood in our house, and those things are people who can't afford firewood, so they will run to dig some and use them back." ”

"Madame's words are wrong, charcoal is much stronger than firewood, and today we will use charcoal for heating."

Li An explained with a smile, of course, until he fully realized the magic of charcoal, Yan Ruyu would definitely not recognize such a dirty thing as charcoal.

"Husband, you made your face like this today, and your hair is dirty, go to the bathroom and wash it at night!"

Yan Ruyu touched Li An's hair, saw that his hands were black, and opened his mouth to suggest.

"Madam, I'm tired today, so I won't wash it."

"No, the husband must wash."

Yan Ruyu insisted.

"Yo, what if the husband doesn't wash it?"

Yan Ruyu was stunned and said boldly: "If the husband refuses to take a bath, then don't go to my bed at night." ”

"Madam is so bold, aren't you afraid to bow hard for your husband and overlord?"

Li An opened his mouth and threatened.

"You...... Don't you dare? ”

Yan Ruyu puffed up her strength, but such a threatening tone, when it came out of her mouth, seemed soft, and there was no deterrent at all, but it made Li An feel very comfortable.

"Haha! Madame has an order, how dare the husband disobey, but the lady has to accompany the husband to wash together, and at night, the husband has to ......"

"Husband, is the grass still here? Talking nonsense again. ”

Yan Ruyu scolded gently, but the words were soft and sound, which made Li An very comfortable.

Ang Lee smiled, carrying a large bag of coal, and walked to the fireplace in the bathroom, where he wanted to light the charcoal himself to verify the staying power of the coal.

Coal is more difficult to ignite than firewood, and it is necessary to light the grass first, then a small amount of firewood, and finally put the charcoal on it, so that it takes a long time to tinker.

Although Yan Ruyu didn't help directly, she kept following Ang Lee, with a beautiful woman by her side, so it felt naturally needless to say.

After the charcoal burned, Li An looked at Yan Ruyu with a smile and said, "Madam, see it!" This charcoal is much quieter than firewood, the fire head is more stable, and the most important thing is that it is more resistant to burning and does not need to be replaced often. ”

"Husband, but I heard that charcoal is poisonous, and many people have died because of burning charcoal, so let's use firewood!"

Yan Ruyu said worriedly, she had long heard that someone had died because of the use of charcoal, so she was very worried about Li An's use of charcoal.

"Madame, don't worry, if you have a husband, the charcoal will not be poisonous."

"Why?"

Yan Ruyu looked curious, and seemed to want to understand the reason.

It is scientific common knowledge that insufficient combustion will produce carbon monoxide, a toxic gas, but if Li An explains it like this, Yan Ruyu will definitely not be able to accept it, so he can only use the reason that Yan Ruyu can accept.

"Madame, do you know why burning charcoal poisons people?"

"I don't know, why is that?"

Yan Ruyu shook her head gently.

"That's because, when the charcoal is burning, if the ventilation in the house is insufficient, it will produce a poisonous gas, which will be killed if it is inhaled into the mouth, and this poisonous gas likes to go up, and the charcoal burning in the fireplace will also produce poisonous gas, but all these poisonous gases will go up and be discharged to the outside through the chimney, and we will not be poisoned in the house, let alone killed."

Li An explained with a pretended expression, and asked Yan Ruyu with his eyes if she understood.

"Is that really the case? The chimney of the fireplace can get the poisonous gases out so that it is not poisoned? ”

Yan Ruyu doesn't understand the specific principle of this at all, she can only believe what Li An says, who made Li An her husband?

"Cao'er, let the back kitchen bring the prepared meals, and let the front yard start boiling hot water, and after eating, take a shower for half an hour."

Ang Lee gave two orders in a row.

Zhao Liu stayed outside the city and didn't come back, although Cao'er was young, he was also a little housekeeper who listened to him, who made him Yan Ruyu's dowry maid? In the future, it is inevitable that she will become Ang Lee's house-filling, and who dares to offend her easily?

After dinner, Li An accompanied Yan Ruyu and took a comfortable bath in the bathroom, and after washing, he did not rush back to the bedroom, but outside the bathroom, while resting on the rocking chair, while observing the burning coals in the fireplace, to determine how long the coals could burn.
