Chapter 410 Are you sure you want to take this job?

The process of making charcoal is not complicated.

But it requires a group of manpower.

Wei Lin was guarding outside the door. When he heard that she needed help, he stepped forward and offered his services: "Princess, do you think we can do it?"

Yun Fu originally planned to ask Cheng Qingyan to go to the mining area to select a group of quarry workers to do this.

After all, making charcoal is a physical job.

Unexpectedly, Wei Lin came to her and brought up this matter first.

"Although burning charcoal is simple, it is a physically demanding job. Are you sure you want to take it?" Yun Fu looked at him and confirmed again.

Wei Lin nodded firmly: "I want to take everyone to try and find a way to make a living here."

They are a group of grown men with families to support, and they can't all rely on the general for support all the time.

"Okay, then you guys give it a try. If it works, the charcoal will be enough for you guys to survive in the seventh-level area."

In fact, these soldiers of the Qi Family Army may not be inferior to the quarry workers in the mining area, because these people have been trained in the Qi Family Army and have strong execution ability. Their character and other aspects do not need to be tested again, and there is no need to worry about them being dishonest or cutting corners.

Yun Fu asked him to call over everyone who could work, and then told them the detailed steps of making charcoal.

"First of all, the charcoal made this time is a little different from the previous ones. We need to select wood with higher calorific value."

Wei Lin and the others listened attentively: "What is wood with high heat?"

Yun Fu explained, "There are many different types of trees in this forest, but the temperature of each type of tree is actually different when it is ignited. Some are high, some are low. High temperatures are required to smelt iron into steel, so the selection of wood for burning charcoal requires some care."

Yunfu listed some woods that generate high heat when burned.

For example, hickory, beech, yellow birch, locust, elm, and oak.

After selecting the wood, we start cutting it.

After felling the wood, split it into small pieces to facilitate full use when burning charcoal and subsequent use.

Wei Lin and the exiled soldiers of the Qi family army were mocked by the escorting officers on the way to exile as good-for-nothings who would never be able to turn things around.

After entering the sixth-level area, they were bullied by the people from Naihe Hall. They said that they were a group of disabled people and if they were unwilling to be dogs of Naihe Hall, they would not be able to survive in the Ghost Prison.

Therefore, they are now trying their best to seize this hard-earned opportunity.

Everyone is full of energy.

After splitting the wood into sections, place it in the sun to make it drier and easier to burn.

The next step is to bury the wood in a pit dug in the earth pile in advance. After it is ignited, the pit mouth is sealed and the wood is allowed to smolder in an environment lacking oxygen. After the fire in the pit is extinguished, the seal is opened and the burnt charcoal is pulled out.

It usually takes a few days.

The first pit of charcoal was completed. In addition to Wei Lin and other exiled members of the Qi family army, the pit was also crowded with people watching the fun.

"I heard they're making charcoal in this pit. You know, after all these days, the wood must have burned out. If we dig it out, it'll just be slag, right?"

"Yeah, it's definitely useless. It's better to just chop it up and use it as firewood."

"All that wood is wasted."

…

Yun Fu had heard this kind of sound when she first burned charcoal in the ninth district. It didn't matter. These people would be slapped in the face later.

"Let's dig a hole."

At a command, Wei Lin led his men to open the pit and dig out the burnt black wood blocks from it. He wondered in his heart, can this thing really be used to smelt iron?

When Princess Yunfu was in Shengjing, she lived a life of luxury, but she probably couldn't even make a fire. Is the wood she burned using this method really useful?

Soon, the answer was revealed.

With crackling sounds, the charcoal gradually burned and continuously emitted heat energy.

It made everyone who was watching feel warm.

"It's really quick to start a fire with this charcoal!"

"I didn't expect this thing to be so useful. I need firewood to keep warm in the winter. Can I order some charcoal from you? I'll trade it for food."

Some people have seen the benefits of charcoal and want to reserve some for the winter.

Wei Lin did not agree, but turned to look at Yun Fu, waiting for her reply.

"It's your business how you want to use the charcoal you made yourself." Yun Fu said indifferently.

"Thank you, Princess." Wei Lin expressed his gratitude sincerely, and the soldiers of the Qi family army behind him also showed gratitude on their faces.

Because they knew that the princess was helping them gain a foothold and survive in the seventh-class district.

Instead of living like a waste.

"Don't thank me, this is the result of your own hard work."

Yunfu was also very satisfied with their work attitude.

——

From now on, the work of making charcoal will be handed over to the soldiers of the Qi family army.

Yunfu is about to start tinkering with the blower.

The blower, which should be called a bellows in the Five Countries, is a very important tool in the smelting and casting process.

However, the bellows currently used by the five countries are all operated manually.

A slightly more advanced form of power is animal power, such as horses, donkeys, and mules.

But these are not suitable for use in blast furnaces.

Whether it is human or animal power, it is time-consuming, labor-intensive and inefficient.

Yunfu searched through the information in the space for a long time. In the absence of electricity, he could only consider wind blowers and water blowers, but wind blowers were picky about the environment and climate and were generally suitable for coastal areas and plateau areas.

So, Yunfu finally decided to make a hydraulic blower.

Hydraulic blower, also known as water blower.

Its operating principle is very simple, which is to convert the water drop into mechanical movement, and then transmit the water power through gears to make the blower work.

Since water power is needed, the ironworks must be built in a place with flowing water, such as a river or waterfall.

The faster the water flows, the greater the power it generates.

The continuous impact of water flow is used to provide power to the blower.

With the previous experience of building a waterwheel, building a blower that also uses water power was not that difficult.

Yunfu drew a detailed blueprint and took the craftsmen selected from the seventh-class district to choose a site first.

Finally, the address was decided in a valley a little distance away from the seventh-class area. The environment in the valley was quiet, and most importantly, there was a turbulent river running through the valley.

This Ghostly Prison doesn't have much else to offer except for its vast territory.

In order to tinker with the hydraulic blower faster, Yun Fu and the craftsmen set up camp directly in the valley.

Cheng Qingyan is in the seventh-class area.

——

Although the seventh-class district is not large, there are many things happening here, big and small.

Originally, Xuanji Zhang was there to share the work with Cheng Qingyan, but now, that guy has taken the job and led people to look for quartz, the raw material for making refractory bricks.
