"Lu Xianhou, are you sure you are burning charcoal?" As for what charcoal smells like, some family officials understand, after all, some family tenants have used charcoal and lost their lives, and these family officials have also smelled what charcoal burns like, so they directly began to question Lu Chen.

And with the questioning of this family official, Wang Qi and Wei Ting seemed to have found a breakthrough, and looked at Lu Chen directly, "Lu Xianhou, what we said is to remove and avoid carcoal toxins, but not to use substitutes!" You're breaking the rules, aren't you? Wei Ting sneered and looked at Lu Chen and said.

"If you don't understand, don't pretend to understand! You say that Ben Hou is not using coal? Lu Chen didn't answer Wei Ting's words, but directly pointed to the family official who spoke just now and said, when Lu Chen said this, the family official suddenly shrunk his neck, you must know that he is also just a small family, but their family has something to do with the Wang family, he was lucky to get a small official, just now he just said that he wanted to help Wang Jue, and let him face Lu Chen alone, he didn't have the courage.

However, this guy is also tough, and he directly stalked his neck and said: "Lu Xianhou, could it be that the official said that he had a sore spot, and he planned to suppress people with power?" ”

"What's your name?" Lu Chen was laughed at by this kid's fake tiger appearance, and asked directly at the official.

"Xiaguan Wei Zhi!" The official directly relied on the courage to report his name, "Could it be that the Marquis of Lu County plans to settle accounts after the autumn?" Wei Zhi looked at Lu Chen directly, ready to use words to trap Lu Chen.

"Put away your thoughts!" How could Lu Chen not understand the meaning of Wei Zhi's words, and glanced at Wei Zhi directly, "Don't think that you can use your words to deal with Ben Hou, Ben Hou has never believed in the gentleman's revenge for ten years, so he will take revenge on the spot!" Benhou wants to clean you up, can you still stand here? Lu Chen snorted coldly at Wei Zhi.

"Okay, don't stare at your two eyeballs, you are really worthy of your name, don't call Wei Zhi in the future, call it mentally retarded!" Lu Chen continued unforgivingly, "Fang Qi, you show him, whether you brought Shi Tan or not!" Let the adults present discern and discern! Don't say what kind of tricks Ben Hou plays! Lu Chen snorted coldly.

On the side, Fang Qi directly opened the burden that was resting on the ground, and saw that there were a few pieces of black honeycomb coal inside, and these officials had never seen honeycomb coal, they all craned their necks to look at Fang Qi's hands, and even Li Yuan craned his neck to look at it again.

In the eyes of these officials, the charcoal is either lumpy or faced, and they have never seen the shape of "honeycomb coal", so they can't help but be a little confused.

"It's true that the color is the same as that of a charcoal, but the shape is clearly artificial!" It was Wei Chigong who spoke, after all, Yu Chigong had been a blacksmith, so he naturally dealt with charcoal, after all, when forging iron, charcoal was much cheaper than coke.

"It's still General Wei Chi who has the eyesight!" Lu Chen recognized Yu Chigong at a glance, after all, Yu Chigong is too black, I am afraid that there are not many people in the Tang Dynasty who can be blacker than Yu Chigong, it is really easy to recognize, Lu Chen said directly to Yu Chigong with a smile.

And with Wei Chigong's affirmation, the civil and military officials present also knew that what Lu Chen took out was indeed charcoal, but it was processed charcoal, and Wei Zhi had already hidden his face and retreated into the crowd at this time.

"Lu Xianhou, why did you make this charcoal into such a shape?" Wei Chigong couldn't help but walk over, bent down and picked up a piece of "honeycomb coal" and looked at it directly, and even looked out through the hole in the honeycomb coal.

"Because it's refined coal!" Lu Chen smiled and explained to Wei Chi Gong.

"What does it mean to be clean?" Wei Chigong continued to ask.

"This coal is poisonous because it contains other components that can cause poisoning, and this component is very abundant in carboniferous, because pyrite is always associated next to the mining of carboniferous mines, and the coal also contains sulfur, if this part of the sulfur is washed out, or the content of this ingredient in the coal is reduced, do you say that the burning of this coal is still easy to poison people?" Lu Chen explained with a smile to Wei Chi Gong.

"Pyrite? Sulfur? What is this again? Wei Chigong continued to ask Lu Chen in the spirit of breaking the casserole and asking to the end, and Li Yuan, who was sitting on the dragon chair at this time, also listened to Lu Chen's explanation with relish.

"How do you explain that? Can I still give them a science about the periodic table? Lu Chen looked at Yu Chigong helplessly and pondered in his heart, "And this thing can't be explained clearly in a while!" ”

"Brimstone knows, right?" Lu Chen thought about it, and then thought of sulfur, after all, there is still sulfur in this era.

"Yes!" Wei Chigong replied very simply.

"I don't know if General Wei Chi has noticed that when those coals are burning, they often smell of sulfur? Or is it rotten egg smell? Lu Chen's mind suddenly flashed, and he remembered what the smell of burning coal that had not gone through the cleaning process was like.

"Indeed!" Wei Chigong nodded, after all, he had worked as a blacksmith, and he knew the smell of burning charcoal when he used charcoal to forge iron.

"What about the smell of burning brimstone?" Lu Chen continued to guide Wei Chigong and said.

After thinking about it for a while, Wei Chigong understood what Lu Chen meant, and said with a smile: "Lu Xianhou means that as long as this sulfur is cleaned out of the coal, the coal can be used normally, right?" ”

"So to speak!" Lu Chen nodded, "But even if it's cleaned, you still have to pay attention to ventilation when using charcoal, after all, this thing still has smoke, and when the air circulation is not smooth, it will suffocate people to death!" ”

"That's right! Right! Lu Xianhou is right! Just when Lu Chen's voice fell, he saw Cheng Biting Jin directly echoing and said, "I heard that the old Cheng Ke heard that those who were poisoned to death by charcoal, and the death was suffocated!" ”

"In other words, Lu Aiqing has found a way to remove this sulfur from the coal, right?" After Cheng Biting King Kong finished speaking, Li Yuan, who was sitting on the dragon chair, asked directly, as soon as Li Yuan spoke, the Taiji Hall, which was still a little noisy, suddenly quieted down a lot, after all, when Lu Chen was explaining Shi Tan just now, many people were whispering, and now that His Majesty has spoken, these people will naturally be quiet.

"Your Majesty, the minister has indeed found a way to remove the impurities in these coals, otherwise the minister would not dare to let the farmers of Lujiazhuang use it!" Lu Chen said directly at Li Yuan.

"Moreover, don't you feel that this Tai Chi Hall is much warmer?" Lu Chen smiled and reminded these officials again.

"It's a lot warmer than just now!" There were officials close to the iron stove who responded directly to Lu Chen.

At this time, it is winter, when the dynasty is on, there will be a few charcoal basins around the Taiji Palace, after all, this huge Taiji Palace, and there is no geothermal heat of later generations, standing in it, inactive, the temperature is absolutely touching, but even if it is placed on the charcoal basin, it is just better than nothing, the main Taiji Hall is too large, and the temperature of the charcoal basin can be much.

The officials close to the iron stove have already put their hands out of the sleeve cage at this time, after all, this is very close to the gate of the Taiji Palace, these officials belong to the back row, the closest to the gate, there is a wind blowing, the first thing to feel is them, so when they go to court this winter, they are used to putting their hands in the sleeve cage, and at this time, because of the iron stove, they can already take their hands out of the sleeve cage.

"Really? Let's feel it! Li Yuan stood up from the dragon chair as he spoke, and walked directly to the iron stove with the support of Chang Bao, at this time the carbon fire in the iron furnace was already strong, and Li Yuan felt a burst of warmth when he was still more than ten steps away from the iron stove.

"Huh?" Li Yuan, who felt the warmth, suddenly raised two eyebrows, if you can feel the warmth at this distance, it means that this iron stove can make an area within a radius of more than ten steps have this temperature, and the closer Li Yuan gets to the stove, the more warmth on his body becomes.

"It's really a god!" When he came to the iron furnace two or three steps away, Li Yuan couldn't help but sigh in admiration, because he had already felt the feeling of baking at this distance, and the temperature was a little hot before that.

At the same time, Wang Qi and Wei Ting's faces have changed, because they know that in this game, they lost again, and this time there is a written note, black and white! Lu Chen got such an iron lump, and directly circled the two of them 15,000 acres of fertile land, and the two of them were now like knives, staring at Lu Chen.

"Why add this?" Li Yuan pointed to the chimney on the iron stove and asked curiously.

"This thing is called a chimney, just now the minister also said, even if the charcoal has been cleaned, there will be smoke when burning, if it is used indoors, the smoke can not be discharged, and it will still make people's lives dangerous at that time, with this thing, you can discharge the smoke of the charcoal to the outside of the house, and the people in the house can use it safely!" Lu Chen smiled beside Li Yuan and explained to Li Yuan.

"Good! Good! Good! Li Yuan said three good words in a row, "In this way, users can avoid killing by inhaling smoke!" And the price of charcoal is low, with this iron stove, the people will have a place to heat themselves in winter! Lu Xianhou, this is another great achievement! Li Yuan stroked his beard and said with a look of relief.

"However, then again, Lu Aiqing is a bit secretive!" Li Yuan then seemed to remember something again, turned his head to look at Lu Chen and said with a smile, "If someone hadn't impeached you today, when would you give this iron stove to me?" ”

"Your Majesty, the minister has been thinking about it behind closed doors at home recently, how to come to see Your Majesty?" Lu Chen looked at Li Yuan with a smile, and directly came to a rake!
