"Marquis Lu, are you sure what you are burning is coal?" Some officials from aristocratic families know what the smell of coal is. After all, some tenants from aristocratic families have lost their lives after using coal. These officials have also smelled what burning coal is. Taste, so he immediately started to question Lu Chen.
Following the question from this family official, Wang Gui and Wei Ting seemed to have found a breakthrough, and they looked directly at Lu Chen, "Marquis Lu, what we promised was to remove and avoid carbolic toxins, not to use substitutes! Are you violating the rules?" Wei Ting looked at Lu Chen with a sneer and said.
"Don't pretend to understand if you don't understand! You said that I am not using charcoal?" Lu Chen did not answer Wei Ting's words, but pointed directly at the official from the aristocratic family who just spoke. When Lu Chen said this, the official from the aristocratic family immediately Shrinking his neck, you must know that he is only from a small aristocratic family, but his family has some relationship with the Wang family. He was lucky enough to get a small official. What he just said was to help Wang Gui and let him face it alone. Lu Chen, he doesn't have the courage.
However, this guy was quite stubborn. He straightened his neck and said, "Marquis Lu, is it possible that I have touched a sore point with you, and am you planning to use your power to overwhelm others?"
"What's your name?" Lu Chen laughed angrily at the boy's fake and intimidating appearance, and pointed directly at the official and asked.
"Your Majesty, Wei Zhi!" The official boldly reported his name, "Is it possible that the Marquis of Lu County is planning to settle accounts in the future?" Wei Zhi looked directly at Lu Chen, preparing to trap Lu Chen with words.
"Stop your petty thoughts!" How could Lu Chen not understand the meaning of Wei Zhi's words? He glanced at Wei Zhi directly and said, "Don't think you can use your words to judge me. I never believe in my words when I take action." It is never too late for a gentleman to take revenge after ten years, so he took revenge on the spot! I want to deal with you, but you can still stand here?" Lu Chen blushed and Wei Zhi snorted coldly.
"Okay, stop staring at those two eyes of yours. You really deserve your name. Don't call me Wei Zhi from now on. Forget it, call it mentally retarded!" Lu Chen continued unforgivingly, " Fang Qi, show him whether what you brought is actually pebbles! Let the adults present identify it! Don’t tell me that I’m playing some trick!” Lu Chen snorted coldly.
Fang Qi, who was on the side, opened the baggage lying on the ground and saw several pieces of black briquettes placed inside. These officials, who had never seen briquettes before, stretched their necks and looked at Fang Qi's hand. Even Li Yuan stretched his neck to look again.
In the eyes of these officials, charcoal is either lumpy or doughy. They have never seen anything in the shape of "briquettes", and they can't help but be a little confused.
"Look, the color is indeed the same as that of pebbles, but the shape is obviously man-made!" It was Yu Chigong who spoke. After all, Yu Chigong had been a blacksmith, so he had naturally dealt with pebbles. After all, pebbles are comparable to coke when forging iron. Much cheaper.
"General Yuchi is still discerning!" Lu Chen recognized Yuchi Gong at a glance. After all, Yuchi Gong's black color is so distinctive. There are probably not many people in the entire Tang Dynasty who can be blacker than Yuchi Gong. It is really easy to identify. , Lu Chen said directly to Yu Chigong with a smile.
With Yu Chigong's confirmation, all the civil and military officials present also knew that what Lu Chen took out was indeed coal, but processed coal, while Wei Zhi had already covered his face and retreated into the crowd.
"Marquis Lu Xian, why do you want to make this charcoal into such a shape?" Yu Chigong couldn't help but walked over, bent down and picked up a piece of "briquettes" and looked at it directly, and even looked out through the holes in the briquettes. .
"Because this is clean coal!" Lu Chen explained to Yuchi Gong with a smile.
"What does clean coal mean?" Yu Chigong continued to ask.
"This coal is poisonous because it contains other ingredients that can cause poisoning. This ingredient is very abundant in coal, because pyrite is always found next to coal mining areas, and coal also contains sulfur. If this part of sulfur is washed out, or the content of this component in the coal is reduced, do you think the burning of this coal will still cause poisoning?" Lu Chen explained to Yu Chigong with a smile.
"Pyrite? Sulfur? What is this?" Yu Chigong continued to ask Lu Chen in the spirit of breaking the casserole and asking the truth. At this time, Li Yuan, who was sitting high on the dragon chair, was also listening to Lu Chen's explanation with great interest.
"How do you explain this? Can I still teach them about the periodic table of elements?" Lu Chen looked at Yu Chigong helplessly and pondered in his mind, "And this thing cannot be explained clearly in a short time!"
"Do you know about sulfur?" Lu Chen thought for a while and then thought of sulfur. After all, there is still sulfur in this era.
"I know!" Yuchi Gong replied simply.
"I wonder if General Yuchi has noticed that when the coal is burning, it often smells of sulfur? Or is it the smell of rotten eggs?" Lu Chen suddenly had a flash in his mind, remembering what the burning coal that had not gone through the cleaning process smells like. what.
"Indeed!" Yu Chigong nodded. After all, he had worked as a blacksmith and knew the smell of burning coal when forging iron with coal.
"What about the smell of burning sulfur?" Lu Chen continued to guide Yu Chigong.
After Yuchi Gong thought about it for a moment, he understood what Lu Chen meant and smiled directly: "What Lu Xianhou means is that as long as the sulfur is washed out of the coal, the coal can be used normally, right?"
"You can say that!" Lu Chen nodded, "But even after cleaning, you still need to pay attention to ventilation when using charcoal. After all, this thing still contains smoke. When the air circulation is not smooth, it will be difficult to hold it in. People are suffocated to death!”
"Yes! Yes! Lu County Marquis is right!" Just as Lu Chen finished speaking, Cheng Yaojin directly echoed, "I, Old Cheng, have heard that those who died of charcoal poisoning were in such a state of death that They’re all suffocated!”
"That is to say, Lu Aiqing has found a way to remove this sulfur from the coal, right?" After Cheng Yaojing finished speaking, Li Yuan, who was sitting on the dragon chair, asked directly. As soon as Li Yuan spoke, there was still some noise. The Taiji Hall suddenly became much quieter. After all, when Lu Chen was explaining charcoal just now, many people were whispering. Now that His Majesty has spoken, these people have naturally become quiet.
"Your Majesty, I have indeed found a way to remove the impurities in the coal, otherwise I would not dare to let the farmers in Lujiazhuang use it!" Lu Chen saluted Li Yuan directly.
"Moreover, don't you feel that it is much warmer in the Tai Chi Hall?" Lu Chen reminded these officials again with a smile.
"It's indeed much warmer than before!" An official who was close to the iron stove responded directly to Lu Chen.
It is winter at this time, and when going to court, several charcoal pots will be placed around the Tai Chi Hall. After all, this huge Tai Chi Hall does not have the geothermal heat of later generations. Standing inside without moving, the temperature is absolutely touching, but Even if a charcoal basin is placed, it is better than nothing. The main reason is that the area of the Tai Chi Hall is too large, so how much temperature can the charcoal basin thing have.
The officials who were closest to the iron stove had already taken out their hands from their armholes. After all, it was very close to the gate of Tai Chi Hall. These officials were all standing in the back row. They were closest to the gate and were the first to feel the wind. They were the ones who arrived, so when they went to court this winter, they were accustomed to keeping their hands in their armholes, but now because of the iron stove, they could already take their hands out of their armholes.
"Really? Let me feel it!" Li Yuan said and stood up from the dragon chair. With the help of Chang Bao, he walked directly to the iron stove. At this time, the carbon fire in the iron stove was already strong. Li Yuan was When I was still a dozen steps away from the iron stove, I felt waves of warmth.
"Huh?" Li Yuan raised his eyebrows when he felt the warmth. If the warmth can be felt at this distance, it means that this iron stove can make this kind of temperature spread over an area of more than ten steps. As Li Yuan got closer to the stove, the warmth on his body became stronger.
"It's really a divine thing!" When he came two or three steps in front of the iron stove, Li Yuan couldn't help but exclaimed, because at this distance he could already feel the feeling of baking, and the temperature became a bit hot further away. .
At the same time, Wang Gui and Wei Ting's expressions had changed, because they knew that they had lost again in this round, and this time there was written evidence, in black and white! Lu Chen just made something like an iron knot and took away fifteen thousand acres of fertile land from them. Now the two of them were simply heartbroken, staring at Lu Chen.
"Why add this thing?" Li Yuan pointed to the chimney on the iron stove and asked curiously.
"This thing is called a chimney. As I said just now, even if this charcoal has been cleaned, it will produce smoke when burned. If it is used indoors, the smoke cannot be discharged, and people's lives will still be in danger. With this It can discharge the charcoal smoke outside the house, and people inside can use it safely!" Lu Chen explained to Li Yuan with a smile beside Li Yuan.
"Okay! Okay! Okay!" Li Yuan said three good words in a row, "In this way, the user can be prevented from inhaling smoke and dying! Moreover, charcoal is cheap. With this iron stove, people can keep warm in the winter. It's settled! Marquis Lu, this is another great achievement!" Li Yuan said with relief, stroking his beard.
"But, having said that, Lu Aiqing is hiding something secret!" Li Yuan seemed to think of something again, turned to look at Lu Chen and said with a smile, "If someone hadn't impeached you today, when would you have given this iron stove to Shall I take a look?"
"Your Majesty, I have been shutting up at home recently to think about my mistakes. How can I come to see Your Majesty?" Lu Chen looked at Li Yuan with a smile, and immediately hit him!
