Unlike ordinary people's coal, which always emits a lot of black smoke when burned, Di Xin was a prince, and even though he was far away from the border, the emperor sent people to deliver anthracite coal as a royal tribute.
Anthracite cannot be completely smokeless, but the slightly rising white smoke can no longer affect the normal air in the house, but will add a warm mood to the cold weather.
However, the amount of anthracite delivered is not large. If there is no restraint, it may be used up in less than half a month.
This is not because the old emperor was stingy, but in this era, the production process of anthracite was complicated and the high cost resulted in low annual output. Except for the emperor, even the queens and concubines in the harem had a limited quota every year.
.
It would be better to say that Emperor Xin was able to deliver anthracite coal at a border far away from the capital, which was enough to show the old emperor's intentions towards him.
Because there were not many of them, basically no one except the emperor would have the luxury to directly use anthracite for heating.
The most common method is to add a small part of anthracite to ordinary bituminous coal. This will not only last longer, but also reduce the black smoke produced when the charcoal pot burns.
There is no limit to the specific amount of anthracite. The more anthracite is put, the less black smoke will be produced.
Of course, servants and maids are not treated like this. Even the eunuchs and maids in the palace can only use ordinary bituminous coal.
With the amount of anthracite given to Emperor Xin, after giving some to Zeng Hongshen and Ouyang Xuan, if he, Wang Ruoqing and Xizi use the rest, the black smoke produced can be reduced by about one-third.
Of course, even ordinary bituminous coal has grades of 3, 6 or 9. The one used by General Mansion is naturally the highest grade, so compared to ordinary people, the black smoke produced is actually less than half.
As for those families who are so embarrassed that they can only use firewood for heating, it is naturally incomparable.
But despite this, Di Xin was a little uncomfortable with it.
As soon as he opened the study door, the soot that poured out together with the warm air in the room choked him and made him cough repeatedly.
"Ahem..."
Laifu, who was waiting beside him, handed over a folded silk scarf very discerningly.
Di Xin glanced at Laifu appreciatively, took the silk scarf and gently covered his nose, feeling better.
This was his mistake.
In the previous life of Blue Star, heating had already become widespread. Although Di Xin was just an ordinary person at that time, he had never used coal for heating. But when he traveled to the prehistoric world, he became the Human Emperor again.
The prehistoric world was a high-demon world. Although the development of civilization at the beginning was not as good as the ancient moon world today, the high-demon world had its own pollution-free constant-temperature magic weapon. Although it was more precious, it was not worth it to a generation of human emperors.
Nothing.
At that time, the brazier candles in the Dashang Palace were mostly used for decoration.
And later on, not to mention the rapid development of the ancient world, Di Xin's increasingly advanced cultivation had already made him not afraid of the cold and heat.
Now is his first time in a mortal body to experience a heating method similar to that of Blue Star's ancient mortals.
However, this was the most luxurious heating method with the least soot except for the emperor in this era. If it were used in an ordinary household, Di Xin might be choked to death on the spot if he took a puff of black smoke.
However, people in this world have become accustomed to it. Zeng Hongshen is an innate great master, and Laifu is just an ordinary person, and he is a bit older. But standing in the study room that is gradually filled with smoke, there is no trace of it at all.
Showing a hint of discomfort.
Di Xin coughed because he was not used to the smoke of coal, but Laifu was too weak after his foundation was destroyed and could not bear the stimulation. He quickly went over to open the window to ventilate the room so that the smoke in the room could be dispersed.
go out.
At the same time, the wind and snow outside the house were also blown into the study.
Laifu bowed and said, "Your Highness, I'm going to get you some clothes to keep out the cold."
"No."
Di Xin waved his hand casually and refused Laifu. When he got up early in the morning, Wang Ruoqing was worried that he was too weak, so she wore two extra linings to serve him, which was already a little uncomfortable. If more were added, it would really affect his movements.
Moreover, his weakness was just an act. His peak martial arts cultivation the day after tomorrow had made his body's energy and blood smooth and smooth, and he didn't even care about a little bit of wind and cold.
However, the black smoke produced by coal soot combustion is mainly due to incomplete combustion, which will produce a large amount of carbon monoxide that is harmful to the human body. People can adapt to the irritation of the nasal cavity caused by black smoke, but they cannot avoid the harm of carbon monoxide to the body.
Chronic corrosion is also another factor. In order to keep warm in winter, many people will close their doors and windows while sleeping even if they burn coal. When the concentration of carbon monoxide in the air is too high, if they cannot wake up in time, they will often wake up in their sleep.
If you defecate, you will suffocate and die.
The great road that Emperor Xin's deity combines is the way of humanity, and the foundation of humanity is the human race.
And this human race is the entire human race in the Void Sea, not just a single realm. Therefore, for Di Xin, improving the living conditions of the human race and improving the quality of life of the human race is not only his own wish, but also the most humane behavior.
"Laifu, go find some blacksmiths and come back."
After sending Laifu away, Di Xin walked behind the desk and began to sharpen his ink. At the same time, he said: "Mr. Zeng, I'm afraid I don't have time to communicate with you about martial arts today. Please forgive me."
"It doesn't matter, I'm not in a hurry for this moment."
Zeng Hongshen watched Emperor Xin grinding ink and asked curiously: "Your Highness, why did you ask Laifu to go to the blacksmith? Are you trying to build some kind of weapon?"
"It's not a weapon."
Di Xin gave up here and chuckled: "As for what to build, let me keep it secret for the time being. Mr. Zeng will know about it soon."
As he spoke, he spread out a piece of paper, picked up the brush, dipped it in the freshly ground ink, and started drawing on it.
Di Xin did not shy away from Zeng Hongshen, but after looking at it for a long time, he could not see what Di Xin was painting, nor could he guess what the purpose of the strange-looking guy with two long pipes was.
But since His Highness said it would be kept secret for the time being, he suppressed his curiosity and waited quietly.
About half an hour later, Laifu returned to the study, and this time there were five more people behind him.
Laifu bowed and cupped his hands and said: "Your Highness, these are the blacksmiths recognized as the most skilled in Yanque Pass. The old slave has brought them all here."
Then he scolded a few people behind him softly: "When you see His Highness King Yu, why don't you kneel down and kowtow as soon as possible."
When the five blacksmiths heard that the person behind the desk was His Highness King Yu, they immediately knelt on their knees and shouted in unison: "I pay my respects to His Highness King Yu."
Their slightly trembling bodies could not conceal their excitement that they were lucky enough to see His Royal Highness Prince Yu.
