In any case, Wei Renshi's family has four more households.

Although there is no land to rent to them for cultivation at the moment, they can only stay in Wei Renshi's house like a long-term worker. But Mr. Wei is optimistic about the prospects.

There will be land, and those wastelands that no one wants can be bought without much effort.

At that time, it will be useful for both farming and breeding.

Even if it is not used as a land for cultivation, it has a place to play.

For example, when Wei Renshi watched Liu Shishi come back with something like black stones, he immediately thought of other uses that those wastelands could be used if they still couldn't grow crops after improvement.

"Brother Shi, you ...... Where did you get the things, and what are you going to do? Wei Renshi stopped Liu Shi and asked.

Liu Shishi replied to Wei Renshi very respectfully: "I want to teach Wei Langjun to know that this is the charcoal picked up on the edge of Pingshan." Although this thing is difficult to burn, it is durable after burning with great effort, and it can be extinguished in the fire pit overnight. ”

"Are there a lot of such coals over there?" Wei Renshi leaned over and took a look, hey, the condition is not bad.

"There should be a lot, and many people will look for it in winter, and some of them can be recovered." Liu Shishi replied: "During the winter, throw a few pieces of this into the stove fire after dark, and there is no need to regenerate the fire when it is dawn." It's not easy to burn it, so you have to put it in while the fire is in full swing. ”

Wei Renshi thought for a while, and then asked, "Is there anyone buying or selling this thing?" ”

Liu Shishi shook his head and said, "I haven't seen that." However, some large blacksmith shops will occasionally accept some. But the harvest is not diligent. ”

"That's okay, Brother Shi'er, let's go!" Wei Renshi nodded, said goodbye to Liu Shishi, and walked in the direction of Fuchang County, but his mind was active, and he ran to Pingshan in Liu Shishi's mouth.

There are so many uses for coal.

In this day and age, although many people have used coal to make fires, the way they use it is too extensive.

And other corresponding technologies can't get up, and there is no place to use coal.

It's just about burning fires.

But even if it's just a fire, the way it is used is too rough.

Moreover, after summer, autumn and winter are coming in the blink of an eye. In later generations, Wei Renshi was most afraid of winter, and he wished that he could hold the little sun 24 hours a day in winter - there was no air conditioning in rural schools, let alone heating, and a little sun was bought from the school with his own money.

This is even more unlikely in this era.

And the charcoal pot is too dangerous and easy to poison people.

Just to feel better for yourself in the winter, this coal has to be made!

If you want to talk about this coal stove, it is also possible to burn coal blocks directly. But in terms of combustion efficiency, it is certainly not as good as honeycomb coal.

In later generations, coal stoves that burned coal blocks became popular again because honeycomb coal was too expensive. In the past, the heat source needed to boil water for cooking has been replaced by gas and electricity, and the coal stove only has a heating function, so the coal stove for heating mixed with firewood and coal blocks has become popular again - it does not need to assume the function of a stove, so the requirements for coal combustion and temperature are not so high.

But if you want to achieve the function of both stove fire and heating, it is better to use honeycomb coal. Honeycomb coal burns fully and continuously, burning more vigorously and at a higher temperature. It is also highly efficient, more coal-saving, and easy to adjust the temperature.

To achieve this purpose, a coal stove is needed, a ventilation exhaust pipe is needed, an internal stove is burned, coal is dug and coal soil is blended, and a manual coal beater is needed.

Wei Ren was thinking about what he needed in order to be able to survive the coming winter without being so painful.

Speaking of which, in the later generations, I am afraid that no one has ever seen a handmade coal hammer by himself in the young friends who traveled through that time!

Wei Ren thought in his heart that the structure of that thing was very simple, and it should not be difficult to find a blacksmith to make it.

Below is a mold of honeycomb coal, the upper end is connected to a hollow rod in the shape of a "ten", the crossbar is the handle, there is a fader inside the vertical rod, and the lower part of the fader is a circular plane, which is connected to the top of the mold.

After the coal soil is prepared, press down on the coal soil with a coal hammer to fill the mold with the coal soil. Then push down the fader that is held up by the coal soil, and the honeycomb coal in the mold will break away. After that, it is dried to make the honeycomb coal.

Wei Renshi grew up in his grandmother's house when he was a child, and there was a coal yard in the village. "One coal and ten water are mixed into paste, and two shovels of coal paste and one spade of soil" have been heard countless times.

And the soil has to be sieved finely, preferably in silt.

It is said that honeycomb coal is the best blended in this way. It is not only flammable and vigorous, but also resistant to burning for a long time, and the cinder is not easy to break after burning.

So what that sentence is going to be - anyway, thanks for the experience. All your experiences will become your capital and help you at some inadvertent or specific moment.

It's not a difficult thing to crush the soil, and the water mill has been there for a long time.

After sifting, it is better to say that the cheapest thing in these years may be manpower.

Wei Ren thought about it for a long time, and when he looked up, he had already arrived at the destination of this trip.

After entering Jiao's Mansion and seeing Jiao Haiqing, Wei Renshi was taken aback and said, "Brother Jiao has lost a lot of weight!" ”

"Really?"

Jiao Haiqing laughed happily, and was about to speak, but Wei Renshi asked again: "Brother Jiao, are you a little relieved, is it too much?" ”

Jiao Haiqing's originally happy smile froze on his face with a smug smile, and he was stunned for a moment: "What? Brother Renshi, what did you say? ”

"Seeing that Brother Jiao suddenly lost so much weight, I'm a little worried." Wei Renshi said: "Brother Jiao has been doing more and more small relief all day and night recently, no matter how much water he drinks, he still feels thirsty, and he always feels tired and tired, and he is always hungry? ”

Jiao Haiqing shook his head and said, "No...... On the contrary, I feel that my body has a lot of strength. I didn't feel much thirsty, and I didn't think much about eating for a day. That one...... There's not much foam on that......"

"That's good." Wei Renshi nodded: "It seems that it is because you drink that gynostemma and Luo Buma, plus the effect of insisting on walking and exercising." If there are those situations that I just mentioned, I am afraid that it is to quench my thirst, and I must seek medical treatment as soon as possible. ”

"I made a note of it." Jiao Haiqing nodded, and asked again: "Seeing that it is noon, Brother Renshi will stay for dinner." ”

Wei Renshi nodded and said, "I'll invite you to dinner, I taught Wang Laohan and his daughter some food some time ago, and I went to taste how they did at noon." And, there's a new business that I want to see if you're involved. ”

Jiao Haiqing's eyes lit up, and he immediately said, "That's good!" Let's get over it! I don't know what kind of business Brother Renshi is talking about......"
