"Boy, the design of your kang is extremely ingenious, so that the house can still be as warm as March in winter, and there is no smoke and dust and other filth, which is really a good idea.

But does your kang need to be burned in the kitchen all night? In the small courtyard of the dean's office, Li Er and Bai Fan sat down separately, and Li Er asked.

Bai Fan said with a smile, "Where is there so much trouble, the fire kang burns charcoal, as long as it is designed, add enough charcoal to burn overnight under the stove, then there is no need for someone to guard the fire all night!" ”

Carboniferous? Is it the black stone that can burn fire? Aren't you afraid of charcoal poisoning?

What the hell is charcoal poison? Then Bai Fan reacted, you should be talking about carbon monoxide poisoning! No, not at all, safe, effective and pollution-free!

Li Er seemed to think of something, slapped his thigh, and laughed, "Boy, you have made a great contribution, do you know?" ”

Bai Fan was puzzled, where did he start?

Then Li Er began to explain, the Tang Dynasty is not strong, there are many poor people and few rich people! In the winter, the rich burn charcoal stoves indoors to keep warm, and good charcoal is so expensive that the poor can't afford it.

In the past, some people found that charcoal can be used to heat the fire, but every year many people die because of charcoal poisoning, but if you don't use this thing for heating, you will freeze to death, so it's like drinking a donkey to quench your thirst!

Bai Fan thought for a moment and said, "That's not right! Even if you burn good charcoal, there will be charcoal poison, don't you say that the rich and noble people did not get charcoal poison because they burned charcoal? It shouldn't be! ”

Li Er shook his head, "Good charcoal is not easy to be poisoned by charcoal, and the rich and noble families arrange special people to take care of it every night, and there is generally no poisoning, and it is a problem for the poor to eat and dress themselves, where can they afford to hire maids and servants?"

Plus it's more dangerous to use coal, so ......"

Understood, the focus is not on raw materials, but on people!

In this way, if the design of your own kang is popularized in Datang, then there are many people in the pankang in winter, and there are many people who can avoid the danger of freezing to death? However, coal as a fuel must be cheap!

"Your Majesty, although the fire kang can solve the problem of charcoal poisoning, but as a fuel, it still takes money to buy charcoal, right?"

The kind of thing that is in the mountains, there are many, many things, and they are not rare in Datang, they are all things used by the poor, and they can buy a big basket for a penny!

But that was before! If the kang is popularized, charcoal will become a necessity that the whole Tang Dynasty needs, and the price will definitely rise, and the rich will still be able to afford it, and the poor will not be able to use it!

Li Er nodded, what Bai Fan said was right, but there was a way to deal with it?

Bai Fan thought for a moment and said with a smile, "Your Majesty often says that officials don't compete with the people for profit!" Today is the time to use these words, all the mining rights of coal in the world will be nationalized, and private mining of coal will be punished and imprisoned if it is sold for profit! ”

That's not right! Aren't you competing with the people for profit?

No, no, Bai Fan shook his head and said, "The so-called merchants are here for profit, but we are not the imperial court, we control the coal, and then we can use that group of foreign captives to mine, after all, this is a dangerous job, the open-pit coal mine is fine, some of them are underground!"

Prisoners are used for mining and transportation, which is equivalent to the imperial court getting charcoal without spending money, and then we sell it to the people at the lowest price at the current low price, presumably a penny can be used for several days!

In this way, we are not competing with the people for profit, but the state controls prices and protects people's livelihood!

If there are those who are even poorer and can't even afford the coal money for heating in winter, like some old and powerless lonely old people and the like, send local officials to verify, and then the imperial court will distribute a batch of life-saving coal for free, so as not to freeze to death in large numbers every year! ”

Yes, good idea, you kid really has ideas, and he is born with a good heart, and he can take care of the weakness of powerlessness, very good! Li Er praised!

Ay! Without him, everyone was in this group of people in the first place! Pick up a life! Bai Fan said with a sigh.

Li Er saw Bai Fan thinking about the past, and didn't want him to be too sad, so he quickly changed the topic!

"Since you can solve charcoal poisoning, do you know anything about it?"

"Charcoal poison is actually a kind of colorless and tasteless light smoke that is not fully burned such as charcoal or charcoal, and it is okay to be inhaled in a small amount, but after inhaling it for a long time, it will be dizzy and vomiting, and it will be life-threatening!

In fact, charcoal poison is only found in unventilated rooms, if the house is open, the doors and windows are open, basically it will not be poisoned, but in winter, everyone wants to close the door to keep warm, so there are so many tragedies! ”

So that's the case, then according to what you say, you put the charcoal in the kitchen, that is, the charcoal poison was left there, and you just passed the fire of the charcoal burning over to keep warm, and it was a good idea!

"Fan also designed a stove with a chimney, which burns charcoal, which can be boiled for cooking, and then uses the chimney to lead the charcoal poison and black smoke discharged from the charcoal to the window, so that it will not be poisoned, and then I will take the drawings and finished products to Your Majesty, since it is to benefit the people's livelihood, then simply make this thing, there is a thing for heating and cooking in winter, and the people can also be better!"

Okay, good, I remember you for a great job!

Subsequently, Bai Fan remembered something and hurriedly said, "Your Majesty, the benefits of coal are too great, even if we have a basket of money, it will be a great benefit, and coal can be used to make steel, so I think that before we have a perfect development and utilization plan, Your Majesty should be cautious, if a bad court can't control it, the people will not get the benefits, not to mention, they may be harmed!" ”

Boy, just say what the hell you want, don't beat around the bend!

Your Majesty is wise, Bai Fan said with a smile!

"Coal is available all over the country, but the output is different, and when the time comes, Your Majesty needs to sell charcoal to the people in various places, can this business be handed over to the beggars? It also gives the beggar disciples in each place one more way to live, and they don't have to worry about them taking advantage of this to prey on the people, the price and goods will obey the arrangements of the imperial court, and they will never dare to make trouble with selfish intentions! ”

You kid is really unprofitable, you can't afford to be early, I can think about this, and I'll give you the answer after the matter is decided!

Bai Fan said anxiously, "Your Majesty has another advantage in handing over this matter to the beggar gang, the beginning of the Tang Dynasty, you can say without hesitation, the officials in various places are still uneven, many places have been occupied by the family all year round, they are like the emperor of the soil in the place, and the people are miserable."

If it is because of the matter of the coal, we give them an excuse to cause these disasters to be the place of disaster, it will be our fault, but if it is handed over to the beggar gang, where dare there be such unscrupulous officials, the beggar gang will have a record, and then His Majesty can start to purge the officials, even if those people are deep-rooted, they will not dare to openly arouse the public anger of the local people! ”

Having said this, His Majesty Li Er nodded, it was a good idea, neither of them broke it, they both knew what Bai Fan said!

The so-called, a century-old dynasty, a thousand-year-old family! Seventy percent of the officials in the Tang Dynasty are controlled by the family, or they are entangled with the family, Li Er wants to replace these people with his own people, but there is no chance, now, maybe it is an opportunity!
