Hearing Zhang Yi's voice, the third uncle woke up, and the son and daughter-in-law of the third uncle next to him also stepped forward to salute Zhang Yi. Pen, fun, pavilion www. biquge。 info

"Uncle, what's wrong with being so late?" After seeing the ceremony, the third uncle asked the family to go to the back room and let the hall out so that the three of them could discuss business.

In his opinion, the uncle is a person who does not go to the Three Treasures Hall for everything, and there must be something very important.

Of course, these things are generally confidential in Zhuangzi, and keeping family members out of it is actually a disguised protection.

Zhang Yi naturally couldn't think of this, so he threw a boiled pea into his mouth, chewed it, and returned to sweetness, the taste was very good, and then he asked the third uncle: "Third uncle, do you know that there is charcoal near our Zhuangzi?" ”

"Coal?" The third uncle was a little surprised, why did he ask about this thing in a good manner? But he still replied, "Uncle, you don't want that thing to make a fire, do you?" “

"Yes! This thing is resistant to burning, and the reserves are very large, do you have it in our Zhuangzi? Zhang Yi nodded and said solemnly: "I seem to have seen it somewhere in Zhuangzi, but I can't remember it, you know?" ”

Speaking of Shi Tan, the third uncle's face was a little ugly, and then he persuaded: "Uncle, Shi Tan is not a good thing, it hurts people!" You might as well use firewood! I know you're trying to save some dry firewood, but you can't use it! ”

As he spoke, the third uncle's face became a little complicated, and his lips began to tremble slightly, and he was silent for a while before he said with difficulty: "Don't hide it from you, uncle, the old man's youngest son died on this coal!" I still remember that winter was very cold, and the mattress at home was thin, and people couldn't stand the cold.....

So I got some charcoal on the ridge of the back mountain and came back to make a fire to keep warm, and it was a very warm night, and the family slept very sweetly. But the next morning, when I came together, I found that the house was full of the smell of coal, so I hurried to their brother and brother to get them up. The eldest and second are unconscious, and the third is ..... Just ......"

Don't think about it, Zhang Yi knows very well in his heart that this is gas poisoning!

In fact, it is no wonder that the ancients almost did not have any knowledge of chemistry, and even if there were, it was discovered by Taoist priests such as Daomen in the process of alchemy. However, after discovering it, they did not announce it to the public, on the contrary, they would package some seemingly magical things in it, saying that they were supernatural powers that had achieved cultivation, thus giving people the illusion of boundless mana.

It is this kind of complacency, since the Western Jin Dynasty, these methods have been firmly controlled by this small group of people within a certain range, and outsiders want to know about it, which is almost equivalent to this person's dream.

And such a thing as gas poisoning is obviously much more profound, and it is obvious that this subject has not been studied in the complacent Taoist learning, so the mining and use of coal will become so unpopular, and even old people like the third uncle blindly believe that the coal itself contains toxins that can kill people.

Thinking of this, Zhang Yi felt that he needed to popularize the use of charcoal and the problem of gas poisoning to his third uncle.

At that moment, Zhang Yi spoke: "Third uncle, in fact, this charcoal itself is not poisonous!" ”

"Not poisonous?" The third uncle and Lao Zhong both spoke out in unison, looking at Zhang Yi in disbelief.

"Of course it's not poisonous!" Zhang Yi affirmed again, and then explained: "Just like you can't use willow chopsticks to eat dog meat, dog meat itself does not have any toxins, on the contrary, it is still a great supplement." But once it comes into contact with willow wood, it becomes a poison that can kill people!

The reason why charcoal can make people die unknowingly is that it emits a large amount of carbon monoxide inside during combustion, of course, you don't understand this thing, you just need to know that this thing is harmful to people, and the culprit is it!

So as long as we control this carbon oxide emissions, we can safely use it for cooking and even ironmaking! “

"Really?" The third uncle still didn't believe it.

"Nature is true! In fact, the use of this charcoal is very simple, we only need to slightly correct the structure of the house! Zhang Yi pointed to the thatch above his head and said: "Let's treat this room as a kitchen, since it is a kitchen, we naturally have to have a stove!" ”

As he spoke, Zhang Yi placed the low table used to hold wine and food in front of him as a kitchen, and gestured and said: "Third uncle, old Zhong, you see, this table is like a stove, and below it is the stove where firewood is added.

But think about it, if you use this method to make a fire, whether it is a piece of firewood or grasswood, the smoke is very strong when it burns, and if there is a certain amount of moisture in it, then this meal can be made to death! ”

Regarding Zhang Yi's statement, both the third uncle and Lao Zhong agreed very much.

As Zhang Yi said, in fact, whether it is a dignitary or a small household, cooking in the kitchen is almost the same. Not to mention cooking, just making a fire is very old, and for this reason there is even a special profession - fire girl!

Don't look at the bad reputation of this fire girl, in fact, it is definitely not easy to become a fire girl.

Because they can make fires very quickly, and can skillfully control the size of the fire, such as simmering, martial fire, and even other different names, different firewood fires are proficient in everything.

The most important thing is that they have less smoke from the fire, which few people are able to do.

Usually the fire girls who have this craft are generally working in high-ranking families, or they are specially trained talents by these families.

"Could it be that young master, you want to find a fire girl?" Lao Zhong couldn't help but say: "But in that case, we won't be able to find someone for a while!" ”

"And the money for the fire girl is not cheap..... the third uncle also interjected.

In their minds, since the charcoal is useful, they only need to pay attention to the charcoal that is burned, so it is very appropriate to ask for a fire girl. The third uncle said that he didn't know that Zhang Yi was cooking for the new food group that was about to be built, but Lao Zhong knew, and he felt that if this charcoal could really be used, even if he invited one or two fire girls, he could save a lot.

"Forget about the fire girl, but what if we added a chimney here specifically for smoke?" Zhang Yi said, put a chopstick erected on the low table, and said: "This smoke is like bamboo, round, but the middle has to be empty, directly from the inside of the house to make a hole in the roof to the outside, so that the smoke will be discharged with this chimney to the outside, and the people inside will naturally no longer have to suffer from the problem of smoke and fog!" ”

"Ahh ....”

The two of them were dumbfounded for a moment, what they didn't expect was that the original fire could still be like this?
