For a modern person, it is not difficult to make money in ancient times, but it is difficult to protect their achievements.

The villagers placed an order, and Liu Feiyun went to the Guo family's blacksmith shop in the city to place an order that day, this is a big order, and Boss Guo bent his waist, so he knelt down to thank him.

The two sides discussed their wishes, saying that they would send twenty sets to Liu Feiyun's house every day, and they didn't need him to come, and the store would serve them home.

And what Liu Feiyun has to do is to mix mud at home, and then fill and dry, or burn a fire to roast, which is faster.

After getting it done, let Li Geng distribute it according to the registration, after all, sometimes, people's hearts are really unpredictable.

Coal stoves were divided one by one, and stoves were quickly replaced, because they were more economical.

The north wind blew bleakly, and the winter snow came suddenly, just like that, the first snow in another world was colder and more urgent, suddenly like a night of spring breeze, and thousands of trees and pear blossoms bloomed.

There are fewer people walking outside, and winter is the most idle time for the villagers, from spring to autumn, harvesting materials for the winter, and a hurried year is nothing more than that.

In previous years, people may often come out to breathe, because the brazier is not used, and it is easy to be poisoned if you stay in the house all the time.

But now it's good, because of the coal stove provided by Liu Feiyun, whether it is firewood or charcoal, it is safer and more economical.

Liu Feiyun didn't say anything about honeycomb coal, not because he didn't want to help everyone, but because this thing was too tiring to make, and the most important thing was that there were many people, even if it was these most simple villagers, but who could determine people's hearts.

Having experienced the torture of the previous life, he understands the temptation of profit best.

The snow outside has blocked almost all the roads, but fortunately, everyone has prepared enough food, as long as the snow melts on some days, and then replenish it, this winter will not be difficult.

"Numb, why is it still so cold." The coal stove is lit in the house, and the best honeycomb coal is used, which has stable heating and sufficient combustion.

But in this cold, Liu Feiyun still felt very cold, even if it was close to the coal stove.

"Have you degraded?" The body is not the original body, but the soul is too mysterious, and now he looks like a modern person who lives in a greenhouse for a long time, and this cooling makes him shiver.

Rubbing his hands, Liu Feiyun drank hot water and shook his feet, and the whole person felt warm. There is no wool wool, no autumn clothes and pants, and no down jackets.

It is impossible for a living person to suffocate to urine, and as a modern person, it should not be a problem to think of a feasible solution.

"Huh?" Liu Feiyun thought about it, and had a lot of ideas in his heart, and he was going to find the simplest one among them.

The solution he came up with was to make something similar to underfloor heating, but it was not that complicated, it was to connect it with some bamboo, and then boil water through it.

But now he can only shake first, the snow is still falling outside, where can he go to find bamboo.

It's boring, he didn't have entertainment in his previous life, but he has something to do in the laboratory, and now he can only stare at the coal stove in a daze, there is too little entertainment in this world.

I finally survived the snow, it was sunny outside, but the temperature was still not high, so I immediately contacted Li San to help cut down the suitable bamboo, and then found a sealing glue. Don't underestimate the wisdom of the ancients, these more practical things can still be found, and they are not difficult to find.

"Feiyun, what are you doing with bamboo?" Li San asked curiously while looking for the bamboo cut of the specifications that Liu Feiyun said.

Liu Feiyun didn't hide it: "Uncle Li, it's a little cold at home, I'll transform it." ”

Regarding Liu Feiyun's statement, Li San shook his head after hearing it, and thought to himself: "The scholar is delicate. However, the movements of the hands did not relax, and soon the two of them moved back to the same amount of bamboo.

After Li San had something to do, he left, and he was also black-eyed when he stayed, and he didn't know how to get it.

The materials are complete, Liu Feiyun's hands-on ability is still good, and soon the bamboo is connected and surrounded around the house, especially by the bed, a few more circles.

After the modification, the combustion fumes will still be discharged, and the special kettle can also boil water on it, and the heat will slowly heat the water inside along the pipes surrounded by bamboo, so that there is a heat source for the whole house. As long as the water is boiling, the constant heat will make the house warmer.

"Yes, yes, very good." Liu Feiyun felt the fruits of his labor, and after closing the doors and windows, the temperature inside was preserved as much as possible, and soon he took off the thick clothes on his body, and now it felt like spring inside.

The cold winter is finally not cold, everyone occasionally comes out to bask in the sun and chat, and when it comes to the coal stove, all of them say that it is good, and everyone praises Liu Feiyun, which even rises to the height of saving lives.

It does have a life-saving effect, and when I used to burn a brazier, I was careless but would kill someone, or that kind of silence. Now you just need to pay a little attention to it, and you won't have a problem.

How to repay the grace of saving lives, these simple people will give him something from time to time, ask him if he is missing, as long as they have, they will try their best to satisfy Liu Feiyun.

Life in the mountain village has quietly passed for half a month, Liu Feiyun has stayed at home most of the time except for teaching the children to study, it is too cold, and the clothes on his body can't stop the cold wind from destroying him.

You know, even in modern times, when you're wearing a fall jacket and a down jacket, sometimes it's not completely warm, especially now that there's nothing.

"Feiyun, you kid wait for me."

On the way back from Liu Feiyun's good class, someone called him behind him, it turned out to be Li Geng, this old man hasn't been to his place for a long time, it is because of the weather, and it has snowed at both ends in three days.

"It's Grandpa Li, what's the matter?" Liu Feiyun asked.

Liu Feiyun's words obviously made him unhappy, and he said with a straight face: "I can't look for you if it's okay, let's go, go and sit with you." It doesn't matter whether Liu Feiyun agrees or not, just pull him away.

Liu Feiyun's home is always lit with a coal stove, even during the day, unless the weather outside is warm.

"Feiyun, you are really a waste, lighting the coal stove in broad daylight, it's all money." Feeling the different temperature in Liu Feiyun's house, the old man began to count him down again.

It's not good to say, but this body is honestly enjoying.

Liu Feiyun has long been surprised by this, this old man is thick-skinned, and he doesn't know how to write shameful words when he is old. Then Liu Feiyun pouted and said: "Feiyun, I haven't eaten your food for a long time, I just happened to be hungry, and the old man will eat at your place at noon, more neat." ”

Look at how shy this is, not even polite.

Full of wine and food, Li Geng patted his ass and left, and left a message before leaving: "The taste is still so good, next time the old man comes again, Feiyun can't hide it, you have to entertain it with good things." ”

He didn't bother to listen to this, he didn't want to come, but you still ate more than me every time.

Life has no waves, the tranquility of the mountain village, especially the snow day is even quieter, if it is not for the occasional smoke rising, who can know, it turns out that there are still people here.

But who would have thought that a huge storm was brewing under the calm.

In Pingyang County, in a luxurious mansion, there are many people sitting in a room, both old and young, the first one is a middle-aged man, not angry and arrogant.

Everyone didn't speak, their eyes were fixed on a bucket-like thing on the ground, steaming, this thing turned out to be a coal stove made by Liu Feiyun, and it appeared here for some reason.

The charcoal in the coal furnace is not treated, and it is burned in one piece, but even so, everyone can see that this coal furnace is extraordinary.

Before the middle-aged man at the top could speak, someone below couldn't wait to say: "Patriarch, this thing must find a way to get the technology in hand, and with the iron ore and carboniferous ore in the family, it will definitely bring us countless wealth." ”

"Yes, Patriarch, it shouldn't be difficult to copy this thing, but this thing can't be known to others, and those who know it now must dispose of it all, so that we can use our own chamber of commerce to sell this thing for a good price."

"Patriarch, I think the person who made this thing can be controlled, maybe he has other ideas."

The people below scrambled to express their opinions, as if they could do what they said.

And the patriarch listened to everyone's words, looked at the coal stove that was still heating again, and said to the next person: "Jiang Cheng, tell me, what is the news?" ”

The patriarch spoke, and Jiang Cheng naturally told him that this coal stove was brought by this person, and he also got it by chance. As a member of the family, how could he not understand the goodness of this coal stove, he must have investigated it carefully.

Jiang Chengdao: "Patriarch, and the elders, this thing is called a coal stove, it comes from a mountain village in Qi County, and the person who made this thing is called Liu Feiyun, the age is unknown, and the origin is not very clear at present, it seems that he is a down-and-out scholar, currently teaching in a mountain village." ”

"The coal stove is a thing he invented to keep warm, regardless of burning wood to cook rice, it can greatly save fuel, and it is better to burn with charcoal and charcoal. Now every household in that village has one, and it is Liu Feiyun who makes the iron sheets from the Guo family's blacksmith shop in the county seat of Tuoqi County, and he adds soil himself to make a coal stove. There is also a matching pipe to vent the smoke toxins outdoors......"

After the introduction, Jiang Cheng continued: "The production cost of this thing is not high, he needs 100 wen to buy iron sheets from a blacksmith shop, and he sells them for 200 wen after he is done, but in fact, a coal stove does not cost much. ”

"So ......"

Everyone knows the power of this thing, and there is an unceremonious saying that even if this thing is not one in every house, but slowly, it will definitely be equipped in every house, because it has such a prospect.

"It turns out that this thing has such ability, and it also appears in our family's territory, it seems that God has made our family last forever." The patriarch smiled, although this thing is simple and cheap, but the value is absolutely huge. What's more, he is not ready to sell this thing cheaply, such a sharp weapon, no matter how you say it, you must be consistent.

After agreeing, the patriarch began to give orders, things must be in hand, but reputation must also be obtained, this is where they can rely on it for a long time.

"Jiang Cheng, you continue to inquire and see how many people are already using this coal stove, record it, and then take it back all outside the village."

"Jiang Shang, you take some money to find Qiyun Cottage, let them get rid of the people in that mountain village, and then you bring Liu Feiyun back secretly, remember, this thing can only be done by those bandits, and it has nothing to do with us."

"There are other people who are going all out to make this coal stove, and when they solve it, they will sell it with all their might, and there will be a long time before winter."

"Yes, I'll understand."

Fixed, so people immediately began to arrange.
