'Coal stove, coal stove, come and see the coal stove. Pen, fun, pavilion www. biquge。 info', an aunt was shouting hoarsely on the street, "If you want to have a warm winter, if you want to buy a coal stove, briquettes are cheap, and you can buy several catties of briquettes for a pound of firewood." ’

'Coal stoves burn briquettes, cheap and fast. Boil hot water in winter and cook vegetables in summer, and buy it to ensure that you don't suffer a loss. In the end, this aunt finally showed that she was not simply promoting coal stoves, "If you want to buy coal stoves, buy Jia Ji coal stoves, the ancestors of coal stoves, easy to use and strong for a hundred years, a hundred years, buy a one that your children and grandchildren will use." ’

Li Chen shook his head when he heard this, this aunt, you should call Jia Ji Coal Stove first, if people listen to the first half of you, don't hear the second half, and buy another one, won't you just shout for a long time?

A few days ago, the government pronounced Jia Xing not guilty, the correct use of coal stoves will not produce carbon gas, if the user has a problem, then naturally can not claim compensation from Jia Xing, coal stoves do not need to be banned.

Li Chen was also relieved to get such a result, this is the best. Although it is a pity that the real cause of death cannot be investigated, although the government has pronounced a sentence, the deceased died because of improper use. However, coal stoves are still remembered for their risk. More or less, there will be concerns when buying.

However, this is good, any product has risks, so that the government can pronounce a sentence, and the blacksmith does not need it, and it is good to be responsible for improper use.

Moreover, although some people will have doubts when they buy it, this matter is so big that it has more or less played a role in promoting it and has become a live advertisement. Therefore, since the day of the verdict, the sales of coal stoves have become more popular, and many people have waited directly near the workshop area in order to buy coal stoves.

Even those official handicraft workshops are not willing to be lonely, and coal stoves have been launched in the past few days, and they are ashamed to say that coal stoves are the invention of the government, and it is better to buy them or buy them. That's why Jia Xing sent the aunt next door to advertise.

In addition, there was a follow-up to the coal stove, and he solved the problem with a design experiment. made him a little disappointed, he, the number one detective in the Tang Dynasty, couldn't open again, this time he was already dead, he couldn't find out the cause of death and completely destroy that Shen Youyi's conspiracy, it's a pity. If this matter is exposed, he would like to see if Shen Youyi will be imprisoned.

In addition, he has made friends with this county order, and the county order is very curious about what is going on with this carbon gas. Why does a closed combustion produce carbon gas?

Seeing that the county order was curious, and his perception of this county order was also good, Li Chen simply continued the experiment. He took out the pre-prepared glass experiment cup, he had long wanted to do a science experiment to show the children, and initially suffered from the lack of transparent glass. Now that the production of glass has gone up, I thought of doing this.

He is not afraid of the covetousness of this county order, the official reputation of this county order is not bad, he is about forty years old, and he came out of the imperial examination. Because of this, the experience is relatively inadequate. This time, it was a matter of concern, and he was blinded by his subordinates due to his lack of experience. Still, he explained that he bought it at auction and that it was not expensive because the styling failed.

Then he asked for a basin of water and two candles. Light the candle and set it up in a small bowl, place the bowl in the center of the basin, and cover it with a glass upside down. The other stood on the table.

The so-called carbon gas is actually a hypothesis. Li Chen began to explain the experiment, "We can't see or touch the air, but can't really measure it?" ’

I heard from some Hu people that there was a place called Greece farther away than them, and the Hu people there thought that there was something in the air, and that people, animals, depended on this to survive. Li Chen pushed how he knew about the existence of oxygen to the ancient Greeks, otherwise he didn't know how to explain this matter, anyway, didn't the ancient Greeks think that the four elements, wind, fire, water and earth?

On closer inspection, this is the basis for the existence of this gas, and the two candles are lit at the same time, one inside, which keeps the air out and one outside. ’

'The water seems to be rising?' The county man on the side suddenly said, don't look at his age than the county order, but this observation is better.

It's not like, it's really rising. The county commander was surprised, "This is witchcraft?" Li Chen slipped, what is this.

It's not sorcery, it's a natural phenomenon, and the burning material in the air is burned out. Naturally, it went out. Li Chen hurriedly explained, he didn't want to be regarded as a demon, "Anyone who does his own experiments can prove it." If you don't have a transparent glass, you can use an ordinary bowl, wipe it dry beforehand, and touch the bowl afterwards to see if the water in the bowl has really risen. The water rises, and although you can't see it, it will naturally wet the inner bowl. ’

'Look, what's burning in the air is gone.' At this time, in the glass, the candle that had been burning for a while suddenly went out. And the candles outside are still burning.

'Who's going to try it, the smell of carbon?' Li Chen pressed the glass with his hand and asked everyone, and everyone retreated, joking, that thing would kill people.

'You say that if you burn in a confined space, it will become like this?' The county magistrate frowned and looked at it for a long time, and suddenly asked. Smart, Li Chen gave him a thumbs up, it seems that he has found a problem.

Why, then, is it that in the same room, some people will be in the middle and some will not? Sure enough, there is no stupid person who can pass the imperial examination, and he found out where the conquest is so quickly.

'How can someone be in the middle and someone not?' Li Chen said with a smile, carbon monoxide poisoning, I have never heard of the same room will not hit, only heard how many people in a room, and the whole family of the first middle school went on the road together.

Died of carbon gas, and only one old man died, how can it be reasonable, carbon monoxide poisoning, will there be a distinction between young and old? It's great to be shallow, found early, rescued after first aid, there is no way to have the kind of person who only dies the elderly, and then others are alive, and they can also complain and sue the official.

Looking at the county commander's expression, Li Chen felt that this was the biggest gain today, no matter how Luo Sihai colluded with the government, as long as he didn't really collude with this nominal supreme official, he still had a chance to maneuver.

Retracting his thoughts, Li Chen has arrived at his destination, he didn't come out to go shopping today, not just to shop. Because the Chinese New Year is coming, I have to take advantage of this last moment to make money and make a good year, so as to have a good year, Li Chen took out the means of Xufu last year, printed Spring Festival couplets, door gods, etc.

But this year, instead of sending the children out on the street to help sell, he hired someone to sell them on the street. It was freezing on this day, Li Chen left the child indoors and strengthened his learning. (To be continued.) )
