If you have the charcoal, you can get the coal stove tomorrow, and as long as you modify it a little, you don't have to worry about the cold in the winter of this world.

However, that night, Li Geng came again, in addition to having a big meal, he also said in a somewhat blaming tone: "Feiyun, how can you buy so much charcoal, so many trees on the mountain, you need to warm up and talk to us, we will help you cut it, why waste so much money!" ”

"Grandpa Li, I have some ideas, I have useful for these coals." Liu Feiyun said, facts speak louder than words, and when the coal furnace arrives tomorrow, I believe they will not have such a statement again.

But this level is not easy in front of him, and Li Geng obviously came to educate him.

"Feiyun, although you are a scholar and your body is a little weak, you must know that for us, food is the most important thing, what's wrong with the cold spots, just add more cloth."

"Also, Feiyun, the reader must have the determination to hang his head and stab the strand, you can't be content with enjoyment."

It's another chatter, Liu Feiyun can only listen humbly, the old man can't be angry with him, in case something bad happens, it will be a big sin.

Finally, the old man said that he was tired and left, and when he left, he didn't forget to say: "Feiyun, I'll come back tomorrow, it's time to change these dishes every day." ”

Liu Feiyun's face was black, you are shameless, it would be good to be able to eat, and there are so many requirements, I myself am not as good as you, and most of the hard-working meals have entered your stomach.

muttering a few words, Liu Feiyun directly lay down and rested. It's dark, because there is no entertainment, and he has also developed the habit of going to bed early these days.

In the morning, Liu Feiyun gave lessons to the little ones, and during this time, this group of children had made great progress, and they could already recite the Three Character Sutra, and Liu Feiyun had taught them most of the words on it.

This enlightenment reading is not available in this world, and Liu Feiyun took out the original one, so he didn't remember it all.

At the beginning of 'At the beginning of people, the nature is good, the sex is similar, and the habits are far away', this Liu Feiyun still remembers, and there are others in the back, such as 'If you don't teach, your father's fault.'" If the teaching is not strict, the teacher is lazy'.

As for the rest, well, he has long been out of impressions.

But isn't it just three words and one sentence, if you can't remember it, we'll make it up ourselves, starting from loyalty, filial piety, benevolence, righteousness, reason, and faith, supplemented by diligence, bravery, and progress.

"Work hard, don't be casual. No matter how much suffering there is, don't flinch...... "Anyway, as long as he doesn't deviate from the main line, this article can still be read, and he is very satisfied when he looks at it himself."

As a result, Liu Feiyun's version of "The Three Character Classic" is not as large as the original and does not have the original refinement, but it is catchy and a good enlightenment masterpiece.

"Okay, let's get here today, after class." Liu Feiyun announced the end of today's course.

"Stand up, goodbye, teacher."

These are some memories of the school that moved from the modern era, so I guess I can give myself some intimacy.

After finishing the morning class and having lunch, he set off for the county seat. Seriously, along the way, he is alone, and it is false to say in his heart that he is not panicking. But there was no danger and he entered the county seat safely.

When he came to the Guo family's blacksmith shop, Liu Feiyun shouted loudly: "Boss, is the boss here?" ”

"In, in." The boss who entertained Liu Feiyun yesterday walked out of it, and when he saw that it was yesterday's customer, he immediately said enthusiastically: "Guest officer, it turned out to be you, the things you want are ready, wait a minute, I'll get it for you." ”

Soon Liu Feiyun saw what he wanted, which was not much different from his impression, and seeing that the thickness of the iron sheet was not small, he was satisfied: "Boss is affordable, this is the last one, you order it." ”

"Yes, yes." The boss took Liu Feiyun and gave him some money, and ordered it in front of him, seeing that there was no mistake, and then seemed to think of something, and said, "This guest officer, do you need the store to arrange delivery for you?" ”

"Oh, are you in charge of the delivery?" Liu Feiyun was still worried about how to take such a heavy thing back, although it was only a few laps of iron, but it was not iron.

The owner of the blacksmith shop seemed to see Liu Feiyun's thoughts, and said, "I'll let the guy send it to you, you don't need to add extra money, as long as you take care of our business more in the future." ”

"Okay, no problem."

In fact, the main reason is that the boss feels that he is not kind, and he is afraid that Liu Feiyun will trouble him afterwards, which will be convenient and we will see each other in the future.

When he came, he walked, and when he went back, he took a carriage, and after arriving at the ground, Liu Feiyun gave the groom a few copper plates, which was regarded as a tip for his hard work all the way, which caused the groom to thank him again and again.

When you're all set, it's time to make a big splash.

The assembly of the coal stove is very simple, as long as it is filled with soil, it is a complete coal furnace when it is dry. The chimney on the top also fits well, as long as you buckle it up, it is a perfect whole.

Not to mention the craftsmanship of the ancients, it is not weak without relying on machines and hands.

The coal stove has been assembled, and the chimney is extended to the outside of the house, so that the smoke poison is well guaranteed to be discharged. All that remains is the burning coal.

Honeycomb coal is troublesome after all, and he plans to get a coal block directly to try the effect.

It is not easy to burn the coal directly, you have to burn it on the outside before putting it in, if you burn it directly inside, it will not burn for a while and a half.

The effect is not bad, the coal burns happily in the coal furnace, and the size of the fire is controlled by adjusting the valve below. Because the whole coal is burned directly, the combustion is not very sufficient, and there is a lot of black smoke, but most of it is led to the outside along the smoke pipe, and some of the things left are because of the airtight problem itself.

The basic requirements have been met, as long as you get the honeycomb coal out again, the combination of the two will be more perfect

However, honeycomb coal is not easy to get, he needs to make coal into powder, other things such as desulfurization and so on, he plans to cooperate with the plasticity of the soil. Then I have to make a tool to press out the honeycomb, and the project is quite huge.

But don't worry, he still has a lot of time, and the weather is not too cold now.

In the evening, the old man Li Geng was more punctual than the alarm clock, and appeared at Liu Feiyun's house again, and saw that Liu Feiyun was tinkering with things he didn't know, and since there was no dinner prepared on the table, Li Geng taught him a lesson: "Feiyun boy, what are you doing, how are you making strange things, you don't eat any food!" ”

However, Li Geng immediately noticed the difference, and directly pulled Liu Feiyun aside and observed it carefully.

"Good stuff, really good stuff." The experience made Li Geng discover the beauty of it, and looked at the smoke outside, isn't this smoke poison.

looked at Liu Feiyun with burning eyes and said: "Feiyun, yes, very good, the brains of readers are different." Come, take care of it, and let the old man see what else is different. ”

The sense of superiority came like this, Liu Feiyun raised his head and spread his hands: "I'll talk to you about it." ”

"You see inside, this is the place where the coal is placed, and this valve is what controls the fire, as long as it is lit, this valve is not closed, it can burn steadily inside. The resulting smoke is discharged down the pipe to the outside so that it is not smoked in winter and poisoning can be avoided as much as possible. ”

"And the burning is more concentrated, and it is faster to boil water and cook rice."

Liu Feiyun showed Li Geng some of the advantages of this stove, a pot of water, boiling on it faster than usual, and then at this time he happened to be preparing dinner.

"Good, good." I don't know if this 'good' is talking about this dinner or this coal stove, but he just stares at the coal stove.

The meal was very fragrant, and the two of them ate one bite at a time, and Liu Feiyun clearly felt that Li Geng's eyes drifted to the coal stove from time to time.

"What is this old man going to do?" Liu Feiyun was vigilant in his heart, something was wrong with this old man.

Dinner was over, this time Li Geng didn't leave immediately, he wanted to stop talking, Liu Feiyun couldn't help but ask, "Grandpa Li, is there something wrong?" ”

Li Geng suddenly played the emotional card and said, "Feiyun, how does Grandpa Li usually treat you?" ”

"Okay, Grandpa Li is very good to me." Liu Feiyun said with a clear conscience, you eat and drink every day, I feel distressed when I say this.

"Well, Feiyun just remembers." Then he asked, "Do you still have this stove?" ”

"That's it for now." He hadn't had time to fill the rest yet, but it should have been quick.

Originally, he was going to tell Li Geng, but before he could react, Li Geng suddenly got up, then picked up his coal stove and ran.

"Won't it be hot, you want me to give you one, it won't be like this!"

Liu Feiyun watched Li Geng hold the coal stove in his arms, and felt panicked, although he had already extinguished the fire before, but it was only a long meal.

Liu Feiyun stretched out his hand, but the words came to his lips without saying anything, because the old man's extraordinary speed had long since disappeared.

"Bandits, hooligans, how can they do such a thing when they are so old."

Liu Feiyun was disdainful in his heart, and you actually want to take it, and you have to take the whole set, this matching cigarette holder is also very important, okay.

The next day, Liu Feiyun got a new one for himself. And Li Geng completely acted as if what happened last night had not happened, he should have come or come, his mouth was full of oil, and when he left, he took away the pipe that he didn't take yesterday, and there was a lot of charcoal.

Fortunately, this pipe is one of the other supporting facilities, Liu Feiyun put them together with coal, and was discovered by Li Geng when he took coal to cook, so that his house could avoid the possibility of being demolished.

It is difficult to hide good things, especially if there is already a person who is outside, in just two days, the whole village knows about it, and they have come to the door, and Liu Feiyun's house is crowded with people.

And Li Geng, the culprit, as everyone's representative, smiled at Liu Feiyun and said, "Feiyun, what do you think of this? ”

It's all like this, what else can I do, Liu Feiyun had to agree, but the problem of this money still has to be said, and he is not ready to pit these villagers, Liu Feiyun said: "I will let people do it, but it takes a hundred yuan to make a stove, and then I will modify it, you see?" ”

Everyone doesn't have any opinion on this, not to mention Liu Feiyun's current status, this thing is supposed to cost money. However, how much is needed, Li Geng opened his mouth, probably because of the short hand, he said: "Just 200 Wen apiece, this thing is good, I have already tried it, cooking rice and boiling water can save a lot of firewood money." ”

Seeing this, everyone thinks that there is no problem, there are more than 100 households in the village, and each family has set one, and this calculation can earn more than ten times.

Thinking about it like this, Liu Feiyun felt that this old man was quite cute.
