If it is said that what Liu Zhang reported is related to the weather, that is, the nights in some places in Jiuquan County have become very cold, and the cold and long winter in Liangzhou is coming. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Of course, the rotation of the four seasons is the law of nature, not to mention Liu Zhang and Hua Fei, it is a person, and he can't control it or dare not control it at all, right? Therefore, Liu Zhang's message is that Hutian will snow in August, and the people of Liangzhou will prepare for winter.

"He'll spend the winter on it, it's impossible for you not to let the family stay out of the winter, right?"

Hua Fei, who was teaching Bing Yuan, Zhang Lu, Ren An and other masters with He Man, Ah Oh Goose and Arabic numerals, frowned secretly after reading the first page of Liu Zhang's urgent report and scolded Liu Zhang for being nonsensical.

However, when he continued to look down, he instantly understood that he was wrong to blame Liu Zhang, who had always been honest and loyal, and what he reported was really a big deal.

Liu Zhang, as the deputy general of the realm, is in charge of protecting the ecological environment, and he is leading a large number of people to plant grass everywhere in Liangzhou, but the people of Liangzhou are cutting down trees everywhere in order to survive the winter.

When Liu Zhang saw this situation, he said at that time! Lao Tzu led people to plant grass and trees, but you cut down trees on the side, but how did Lao Tzu not get angry?

Liu Zhang felt that this matter was intolerable, so he sent a large number of people to dissuade him, and at first the people of Liangzhou also listened to it.

But then Liu Zhang and others slowly persuaded them not to stop, and the people were just hiding and cutting at first, but now it has almost developed into an armed conflict.

So Liu Zhang couldn't stand it, he was afraid that if there was a civil uprising, Hua Fei would pick up the skin, and their general, Zhang Song, had already gone to Xiqiang with Pang Tong and others, so he could only ask Hua Fei for help.

Hua Fei was very surprised when he saw this, so he raised his head and opened his mouth to Bing Yuan and the others and asked, "What do you say the people of Liangzhou are going to do when they cut down trees?" ”

"I know this!" He Man, who had been listening to the thunder from the ducks, raised his hands and opened his mouth and shouted, "When winter comes, they have to burn wood to make charcoal, and when it snows, they can keep warm, so that they can survive the winter." ”

After shouting, he raised his chin and glanced at everyone, and he felt proud in his heart, and said in his heart: What is it? When I can answer the lord's questions, don't always take me as a fool in the future.

It's a pity that none of the people in this room paid attention to him, after all, they all boasted that they were talented people, so how could they compete with this one? Isn't that self-surrendering? So it made He Man proud in vain.

"Burning charcoal?"

Hua Fei repeated He Man's words in his mouth, but he also understood in his heart, this Liangzhou is located in the northwest, and the winter is extremely cold, and it is reasonable for the people to burn charcoal for warmth.

Because you can't get someone to hold a sheep in your arms, can you? Whether it stinks or not is another matter, but this body of lice, fleas, parasites, etc., is enough to make people unbearable.

However, cutting down trees will destroy the ecological environment, and the desertification in Liangzhou is serious enough, so we can't continue to destroy it while it is being treated.

Thinking of this, he raised his head and asked Bing Yuan and the others: "In the territory under our rule, is it said that there is no coal produced?" ”

Cutting trees to make charcoal will not only damage the ecological environment, but also the charcoal is large and light, and it is easy to "crackle" when burned, and the sparks will also jump around, which is especially easy to cause fires.

Coal is a mineral formed by long-term precipitation, not only is it easy to cause fire if it does not have a burning head, but it will not damage the ecological environment if used in small amounts, so Huafei is ready to replace charcoal.

"Coal?"

Bing Yuan, Zhang Lu and the others glanced at each other when they heard this, but they all stared at Hua Fei for unknown reasons.

"Uh...... How do you say that? ”

Hua Fei suddenly remembered that people in this era may not call coal coal, but he didn't know what it was called, so he felt a headache and tapped his forehead with a slightly cool Buddha bead.

After a while, he muttered and said slowly: "This thing is black all over its body, and when you touch it, it is full of ink, it can be burned and it is dry, and it is usually buried underground, by the way, it should be much special in the area of Bingzhou." ”

Hua Fei can't say the name, so he can only start by looking for characteristics, plus the state is similar to Shanxi in later generations, what is the most famous in Shanxi? Although Hua Fei is a little lonely and unheard, the boss of Shanxi Coal is only afraid that he has also been famous in the epicenter, right?

"The color is black and easy to fade, it can be burned and stored on the ground, and there are many special states?"

When Bing Yuan and the others were stroking their long beards and repeating Hua Fei's words to use their brains, they suddenly heard He Man, who looked similar to Yaksha, raise his hand again and shouted: "I know!" ”

"I rub! You know? ”

Bing Yuan and the others almost twisted off their beards, and stared at He Man with round eyes one by one.

This cargo is Hua Fei's personal bodyguard, so he often comes to teach with Hua Fei, but because his brain is not very bright, as long as Hua Fei asks a question, he sits like a good baby and sits without saying a word.

Today is good, Hua Fei finally asked two questions outside the classroom, but he asked this famous stupid big man in the whole army to answer it, but this is called Bing Yuan, who boasts of being rich in five cars, how can he be embarrassed?

So all the old masters stepped forward with angry eyes, and they all stretched out their fingers and pointed at He Man and roared: "Say! ”

He Man was taken aback by them at that time, and said in his heart: What do you old guys want to do? How did it look like I was going to be eaten alive?

He didn't know that it might be impossible for Bing Yuan and others, who had lost face, to eat him alive, but if he didn't say it right or couldn't say why, then a ruthless verbal punishment was absolutely indispensable.

Although He Man couldn't figure out the situation, Bing Yuan and the others were all people who were highly respected and valued by Hua Fei, and they didn't dare to slack off when they saw that they were angry, so they hurriedly opened their mouths and said, "I think what the lord said may be graphite." ”

"Graphite?"

Bing Yuan and the others repeated in unison, and their eyes lit up for a moment, and Hua Fei saw this posture, and immediately felt that He Man might have guessed correctly.

Sure enough, Bing Yuan immediately clapped his hands in agreement in the sound of "pop": "Yes, yes, this graphite was also called Shihuang or Shini in the pre-Qin period.

The shape and characteristics of this object are the same as the description of the lord, and according to the records of ancient books, there are records of iron smelting in the Western Han Dynasty. ”

"Dig the grass! It turns out that coal has been used by people before my Great Heavenly Empire, and my Great Heavenly Dynasty is really extraordinary! ”

Hua Fei secretly admired in his heart when he heard this, but then opened his mouth and said loudly to He Man: "Hurry up and ask people to invite Pu Yuan or Ma Jun, I have something to tell them to do." ”

"Whoa!"

In He Man's reply, Hua Fei turned to Bing Yuan and asked, "Since I have been using graphite for a long time, why haven't I seen anyone using it now?" ”

To be honest, he doesn't care too much about when the Han Dynasty started using coal, what he cares about is why this thing has been used and why it should be abandoned.

But I heard Bing Yuan say: "My subordinates don't know the specific reason, but I heard that burning this kind of thing will poison people to death, and this thing itself is black and easy to fade.

What's more, this season is a time of chaos, and it's too late for the big guys to earn their lives in a hurry, and how can anyone have the time to learn rats to dig holes to collect this thing? ”

"Tyrannical creatures!"

Hua Fei sighed secretly when he heard this, you must know that coal was the most important mineral before other energy sources were developed in later generations, and even cinders were very useful.

Thinking of this, he no longer paid attention to the pen of the crowd and wrote and drew on the paper, fortunately he had seen people printing coal and burning fires in later generations, and he still had some impressions of the items that seemed to be called "honeycomb coal".

So when Ma Jun and Pu Yuan both arrived, they saw several shaped drawings, including hand-made coal printers, coal stoves, tongs, and chimneys and skylights for ventilation.

After introducing the uses and precautions of each tool to the two of them, Hua Fei taught them to collect graphite and grind it into powder, mix it with loess, add water and form a thin mud, and then use a coal printer to make the shape of honeycomb coal......

After teaching these two capable people, Hua Fei left the matter to the two of them to handle, but then in the eyes of Bing Yuan and others full of admiration, they looked at the northeast and started a new idea. (To be continued.) )
