Only when the villagers spend their money can the circulation of money be promoted and the economy gradually improved.

What's more, they didn't spend money recklessly, and the things they bought were all daily necessities.

Although it is not food, in the winter when water turns into ice, even if there is food, without anything to keep warm, you can still survive for a short period of time. But if it is like this for several months in a row, not to mention the elderly and children, even young and middle-aged people will find it difficult to persist.

She prepared to make honeycomb coal in advance. Her ultimate goal was not for the villagers of the seven villages, but for the entire Wuning County or Qingshan Prefecture.

According to the data obtained by a full set of geological monitoring instruments, there is a super-large coal mine on the small hill. Even with advanced equipment of the later era, it will take at least 40 to 50 years to mine the entire coal mine. You can imagine how big this coal mine is.

Therefore, Mengyue was not worried about the lack of coal blocks at all. As long as she could recruit enough manpower, mine the coal as soon as possible, and then make honeycomb coal.

If you want to make honeycomb coal, you don't just need coal blocks. You also need quicklime, yellow mud, sawdust and other things. Mix them together in proportion to make coal mud. Then use tools to make honeycomb coal and dry it in the sun.

Although this slows down the process, there are reasons why it must be done.

After all, gases such as sulfur dioxide, hydrogen sulfide, nitric oxide and carbon dioxide produced by coal combustion are harmful to the human body.

As long as the doors and windows are closed during the burning of coal to make the room more heat-insulated, people will feel dizzy and their brains will swell up in a short time, and in severe cases, they may lose their lives.

However, if it is made into honeycomb briquettes, it will not have that pungent smell and can also reduce the harm to a certain extent.

When it is closed, it does not mean that you will not be poisoned, but the risk will be greatly reduced. As long as you pay attention to ensuring indoor ventilation and don't get too close, there will be no problem.

Judging from the current situation, before the arrival of the extreme cold Little Ice Age, a sufficient amount of honeycomb coal must be made to allow people to survive the cold winter.

After discussing the coal matter with the seven village chiefs, the village chief also agreed to select fifty people, and Mengyue was ready to go home.

She plans to make some honeycomb coal first so that everyone can have a direct understanding.

Because she knew that even if she told the seven village chiefs about the coal blocks and the place where they could make honeycomb coal, they would not believe it too much.

But Mengyue knew that the village heads could not be blamed. It was really because what she said about coal blocks and honeycomb coal was beyond their understanding.

It can be said that before she brought it up, not only the village chief, but even the higher-ups didn't know about coal blocks and didn't understand their importance.

Not to mention anything else, Xie Ruiyuan was the third prince, a god of war general who was feared by the world, and the only prince to be conferred the title of prince. When she mentioned the word "coal", Xie Ruiyuan was surprised and didn't recognize it, let alone ordinary people.

In other words, no one in this era had discovered the uses of coal, and coal mines were still unknown to the entire Zhou Dynasty.

Mengyue was well aware of the extremely cold Little Ice Age sweeping across the northern part of the Great Zhou. In order to save more people from dying in the severe cold, the only way was to mine coal and produce enough honeycomb coal.

There is a coal mine on the hill that needs to be mined as soon as possible, and fifty people are far from enough, and I'm afraid a thousand people won't be enough either.

The reason she asked the village chief for fifty people was mainly because the refugees were not being utilized.

Once the refugees come in, we won’t have to worry about lack of manpower.

So after Mengyue finished talking about the coal mine business with the seven village heads, they got up and went home.
