A few days later

"Liu Gongzi, it's all three poles in the morning, you should get up too."

Qian Youcai came to the door of Liu Jin's room, and when he saw that Liu Jin hadn't gotten up yet, he said helplessly.

The ancients generally went to bed very early and got up very early, Liu Jin was crossed over by later generations, and he still retains the living habits of later generations, and he will never get up before seven or eight o'clock.

What's more, now that the weather is cold and the cold wind is howling outside, Liu Jin is even more accustomed to lying in bed, if there is nothing to do, Liu Jin can sleep until noon.

Regarding this point, Qian Youcai also shook his head more than once or twice, in his opinion, Liu Jin is good at everything, very talented, humble, whether it is for himself or the villagers of Xishan Village, he has always been kind and very polite, and everyone likes him very much.

But this problem of sleeping lazily has never been changed, which makes Qian Youcai, who is eager to bring honeycomb coal to the market as soon as possible, also shakes his head.

"Okay~ Okay, I'll get up right away."

Liu Jin's lazy voice came from the room.

Qian Youcai didn't wait long, a few minutes later, Liu Jin had already dressed and walked out, as soon as the cold wind blew, Liu Jin couldn't help but shrink his body and said: "Old Qian, can you not wake up early in the morning in the future, this kind of weather, don't sleep a few times, it's really a waste of this rare good weather." ”

"My son Liu, it's already the hour, and you haven't married a daughter-in-law, what are you doing in bed, you get up early and go to bed early, and your health is good."

Qian Youcai looked at Liu Jin and shook his head again.

"I also know that it's good to go to bed early and wake up early, but I can't change it."

"Don't talk about this, why did you wake me up earlier, what's the matter?"

Liu Jin yawned, looking like he hadn't slept enough.

"Our first batch of honeycomb coal has been dried, and you should teach me how to use it now."

"I've learned it here, so that people can take it to the capital and sell it as soon as possible, this white silver is spent every day, you don't know this feeling."

Qian Youcai also said while taking Liu Jin to the honeycomb coal production workshop.

How to use this honeycomb coal, Qian Youcai has been thinking about it for a long time, but I always feel that it is wrong, especially when combined with the honeycomb coal stove, it feels that how to use it is wrong.

"It's easy~ I thought you should be able to figure it out yourself."

Liu Jin was slightly stunned, he didn't expect it to be this.

Soon, the two of them came to the honeycomb coal production workshop, and many of Qian Youcai's men were already waiting at this time, and some people were constantly thinking carefully about how to use honeycomb coal.

"Liu Gongzi is here, you all have to watch and study carefully, have you heard?"

Qian Youcai looked at these guys under his hands, and also said sharply.

When the guys heard this, they all immediately cheered up and said, "I heard it~"

Liu Jin looked at the crowd, took two honeycomb coal stoves and began to teach.

"Let's take a look, there are two kinds of honeycomb coal stoves, this kind of one we call it a single-core coal furnace, that is, only one honeycomb coal can be put into it at a time."

"This kind of honeycomb coal can be put into three honeycomb coals at the same time, we call it a three-core coal furnace, and the two coal furnaces have the same structure except for the difference in the amount of honeycomb coal that can be loaded at one time."

"Because this single-core coal furnace can only hold a stack of honeycomb coal, the heat generated when it burns is limited, and this furnace is not large, so it is generally more suitable for boiling water and heating."

"This three-core coal stove, which can triple stack honeycomb coal at the same time, produces high heat, and the stove is also large, which can be used for cooking, boiling water, heating and so on."

Liu Jin took two honeycomb coal stoves and began to explain to these guys.

"So when we promote honeycomb coal, we need to be flexible, carefully ask about the needs of customers, and then recommend suitable coal stoves."

"There is a small opening under this coal stove, this opening can be covered and opened, when we need to use fire, we open this small opening, and when we don't need to use fire, we can cover it, which can save coal."

"When the honeycomb coal is just used, it is necessary to first burn a piece of honeycomb coal, and then put the honeycomb coal at the bottom of the coal furnace, and then add other honeycomb coal to the top."

Liu Jin also started to operate as he spoke, and these guys with money and wealth had already prepared all the tools in order to study how to use honeycomb coal, and there was charcoal that had been burned on the side.

Liu Jin put a few pieces of honeycomb coal into the charcoal to slowly burn red, and then put the honeycomb coal at the bottom of the coal furnace, and then added honeycomb coal on top of it.

"If we feel that the fire is burning too slowly, or not big enough, we can also use a fan to fan the air here and there, so that we can speed up its burning and make it completely burn quickly."

With Liu Jin's operation, the honeycomb coal in the coal furnace quickly burned red and began to emit billowing heat, which made the eyes of all the people around him light up.

"I see, it's so simple, we thought about it for a long time, but we didn't even come up with it."

Someone suddenly said.

"I haven't been able to understand the role of this small opening, it turns out that it is similar to the function of a blower, which can be used to blow air and increase firepower."

"Tsk, this is full of firepower, the heat wave is scorching, and this size is just right, just about the same size as a pot, it can be used for cooking, and it can also be used to boil water, it's really convenient."

"No, if we really use this, it will be much more convenient for us to cook and boil water in the future."

Everyone quickly realized the benefits of this honeycomb coal stove, which is very convenient to use, and the key is that it is durable enough and high in calories, which is much better than burning firewood.

"When this honeycomb coal is used up, that is, the coal in it is burned, I can take out the honeycomb coal burned at the bottom, and put it back layer by layer, and add new honeycomb coal at the top."

"Of course, I'm just demonstrating here, this piece of honeycomb coal can't be burned so easily, only when its color turns white, it's really all burned."

"In addition, if we don't need to use it, we can cover this small opening, and after covering this small opening, the honeycomb coal inside will burn very slowly, very slowly, and will not waste honeycomb coal."

Liu Jin looked at everyone, smiled and continued to demonstrate in person.

As Liu Jin covered the small opening of the honeycomb coal stove, the originally red-burning coal stove was slowly extinguished, and only a very small amount of honeycomb coal at the bottom was still burning very slowly.

If it is the people of later generations, they must know that it is because of the lack of oxygen, so it cannot be burned, as for the ancient people, they only need to tell them to do this, as for the truth, there is naturally no need to explain.

"If we need to use it, we open the lid of the small opening, fan the wind from here, and soon it will be burning again."
