Crossing Wu Dalang starts from selling cakes

Chapter 617 Honeycomb Coal!
Especially the capital Kaifeng.

Although the whole country was mobilized to ensure the supply, firewood was too bulky to store and transport.

The problem is especially serious in winter when there is heavy rain and snow and the people are bitterly cold.

At that time, the Song Dynasty took great pains to solve the firewood shortage.

In addition to engaging in cheap firewood, a national firewood reserve system has also been established to prepare some fuel charcoal and sell it when the price is high to calm the market.

However, charcoal is bulky, too scattered, transported over a long distance, and far away from water is hard to quench thirst, and the most important thing is that there is a shortage of firewood in the whole country. How can Kaifeng survive alone?

It was not until the middle of the Northern Song Dynasty that this problem took a turn for the better.

A new fuel appeared in Kaifeng, its name is coal, which is today's coal.

In fact, coal was not a new discovery at that time. At the latest in the Han Dynasty, coal had begun to be used as fuel, and it was called coal at that time.

During the Three Kingdoms period, Cao Cao built the Tongque Tower and stored hundreds of thousands of catties of coal under the platform.

After the Tang Dynasty, smelting, brewing and other workshops have generally used coal as fuel.But for ordinary residents, very few people use coal.

Most importantly, if this kind of coal is used for heating at home, it is tantamount to courting death.Because it is poisonous.

After all, the ancient refining technology is still much worse, which is one of the reasons why coal has not been popularized.

But at present, we can only start with coal. Da Song already has a certain amount of mining resources. As long as large-scale mining and refining are needed, it can be supplied.

Refining is a technical job, and Wu Zhi has no shortage of skills. Thinking of this, he was ready in an instant.

Wu Zhi made a thought, and the Minister of the Ministry of Industry saw it. He didn't know whether Wu Zhi really had no way or didn't want to help him.

From Wang Juan's point of view, he thinks that Wu Zhi really has no other way.

He thought hard and couldn't think of a way to save the current predicament. This winter is not ordinary cold.This is disaster.

It is more serious than the previous heavy snow.

He hopes that Wu Zhi has a solution but he is unwilling to help him. As long as Wu Zhi has a solution, he can continue to ask for it. After all, there is hope.

Wu Xiangruo has nothing to do.

The performance of the Ministry of Industry this year is too poor.

They are responsible for these things. Winter is about timber and other things. Although the lack of supply is not his fault, but it can't solve the problem, it is incompetent.

Could it be that Wu Zhi wanted to take advantage of this incident and bring him down?
Wang Judgment felt that the possibility was unlikely.

Seeing that Wu Zhi was silent, Wang Juan sighed and cupped his hands: "Since Wu Xiang didn't think of a way, I won't bother you."

Wang Juan turned and left.

"There is a way!
Wu Xiangdao: "I have thought of a way to do this, but I need your cooperation!"

Wang Pan's body shook, and then he smiled happily. Wu Zhi's words are what he loves most at the moment.

"Wu Xiang said, let me do anything, the king will do everything, and I will go all out!"

"Okay." Wu Zhi nodded: "How many people from your Ministry of Industry work in the coal mine?"

Wang Juan was stunned: "The Ministry of Industry does not have many people in the coal mines, about 300 people. But there are tens of thousands of coal miners recruited from outside, but there are not many people working in the coal mines, so the output is not very good, and it is poisonous. , why... Prime Minister Wu wants to mine coal mines?"

"Not bad!"

"That won't work!"

Wang Judgment directly refuted it.He seemed to feel that he was being too arbitrary, so he quickly smiled and said, "Mr. Wu, what I mean is that although there are coal mines in Song Dynasty, there are some poisonous smoke in the coal mines. If coal mines are really used, safety is another big problem. Using coal mines to solve the cold season this time may backfire and kill more people.”

What Wang Juan said was not unreasonable.Because many people died in coal mines, they were poisoned to death carelessly.

The burning of coal mines releases a large amount of poisonous gas, many of which are chemical substances, which are unbearable to humans.

But there is no pure refining technology. Wu Zhi has it and knows how to do it. In this way, the toxicity is greatly reduced, so it is not a big deal.

"You don't have to worry about the coal mine problem. Do you really want to solve the problem?"

"What Prime Minister Wu said, the lower officials are looking for you to solve this year's natural disaster and the problem of charcoal materials."

"Then you listen to me, now order people to gather the coal mines in the Ministry of Industry, and I will teach you some methods to ensure that the coal mines can be used by the common people!"

"it is good!"

The method Wu Zhi thought of must be something he had never seen before. Although he doubted it at the moment, he left immediately.

After returning to the Ministry of Industry, he issued an order for the person in charge of a nearby coal mine to transport the coal to the Ministry of Industry.

Another meeting was held with the officials of the Ministry of Industry, and the matter was told, and Wang Pan's subordinates were a little surprised.

There was even laughter.

Coal mines cannot be popularized at all. People in the Ministry of Industry know this. Minister Wu said that coal mines should be refined for the common people. Isn't this nonsense.

It was Wu Xiang's idea, and they had to listen to Master Shang Shu's order, so they all went to prepare.

In a few days, truckloads of black coal mines were transported to the office of the Ministry of Industry.

The yard is very wide, even if there are mountains of coal mines here, there is still a lot of open space.

A group of officials from the Ministry of Industry surrounded the coal mine, whispering.

What they talked about was that the coal mine was too poisonous, and the people who used it to death for the common people were probably no worse than those who died of freezing.

If it backfired, it would be ridiculous.

Everyone gathered, and Wu Zhi came to the Ministry of Industry.

He is drawing drawings.

Wu Zhi did not follow Da Song's refining technique, but followed the best refining method he bought in the system.

First of all, the coal mines originally mined are toxic and contain very high levels of sulfur and oil.These two things must be removed, and then crushed and mixed with soil, it can be made into the briquette that Wu Zhi wants.

These two substances filtered out by refining methods are also valuable, and can be used to make kerosene and sulfur.

Cave dwellings have been established in this courtyard for the purpose of concentrating on imparting techniques.

Those present were all officials from the Ministry of Industry and senior management of coal mining.

Wu Zhi is not worried about rumors, and now it is not a matter of rumors or rumors. The coal mine must be brought out.

"You have to wash these coal mines first to remove the impurities in them, and then dry and grind them into powder and mix them with clay. Let's do this first!"

Although everyone didn't understand, and they laughed at it before, but they didn't have the guts to question the prime minister in front of him.

Wang Ping didn't ask any questions, just wait and see the result.

In case Wu Zhi, who asked the question, got annoyed, it would be bad if he ran away.

A group of people in the courtyard started to work.

The on-site coal mine is only used for making a model.

In a few days, the task assigned by Wu Zhi to the Ministry of Industry has basically been completed.

From these coal mine materials, [-] briquettes were made.

In addition to making briquettes, they also built more than [-] coal stoves according to Wu Zhi's requirements.

The ability of the Ministry of Industry is still very strong.

At this time, everyone will see how Wu Zhi operates.

Wu Zhi came over, put a piece of black briquette in the stove, lit the wood next to it and put it in the bottom of the stove.

After the first piece of briquette turned red, Wu Zhi added two more pieces of briquette to the coal stove.

As time passed, the three briquettes glowed red and glowed in the coal furnace.
