Chapter 172: Village Chief, are you going to start the process?
After a night's rest, Yun Fu's energy was mostly restored.
After a simple meal, I was preparing to start reorganizing the mining area.
Something happened.
"Early this morning, Tieniu led a team of people down a newly dug mine, intending to mine more black gold stone. Unexpectedly, a large amount of water suddenly flooded into the mine, and none of the people down there were able to get out."
Yunfu knows that mining involves many security issues.
Only by avoiding these problems as much as possible can we reduce the occurrence of mining accidents.
This is also what she will focus on when she reorganizes the mining area.
However, she didn't expect that the accident had already happened before she could say anything.
When mining coal, digging through the cave wall, connecting to groundwater or abandoned mine tunnels with accumulated water may cause mine water seepage accidents.
Water sources mainly include surface water, aquifer water, fault water, old empty water, etc.
Yun Fu immediately rushed to the scene.
Through the descriptions of people around me, I have a more detailed understanding of the current situation.
Judging from the water level in the mine at this time, the quarry workers must have dug through the aquifer when digging the cave wall, causing water to seep into the mine.
Now the water level has stabilized and is not rising any further.
In addition, there is another very important point, that is, the trapped people are all good at swimming, and there should be a mine near where they are, and the terrain of that mine is higher.
If they had been able to retreat safely into the mine, given the current water level, they might still be alive.
"Alive, but only temporarily. The mine is a dead end. They can't get out, and we can't get in. They can only wait to die in there."
This is probably not the first time something like this has happened in this mining area.
Yun Fu wanted to know how they had dealt with it before and whether there was any solution.
Yun Fu had many ways to solve the problem of water seepage in the mine in her mind, but the problem was that these methods were difficult to work in this ghost place.
For example, using diving equipment, we can go down and rescue people one by one.
For example, use high-power pumps to drain the accumulated water in the mine.
But the answer she got was that there was no solution.
In the past, when people encountered such things, they could only wait for death.
It’s not that they don’t want to save people, but the water is so deep and it’s pitch black under the water. No matter how good a person is at swimming, they wouldn’t dare to take the risk.
In Yunfu's dictionary, there is no word "waiting to die".
Now that she is not sure if they are dead, she will treat them as if they are still alive. Seventeen or eighteen lives are under her nose, so she must find a way to save them.
She walked around the mine and found that there was an even deeper abandoned mine not far away.
Yun Fu followed the rope down the mine and found that there was a mine tunnel that was heading towards the mine next door where the accident occurred.
She measured the distance with her steps and then asked a quarry worker who was familiar with the terrain to confirm the height of the mine tunnel.
Finally, a conclusion was drawn.
If, this mine tunnel is blown up from this side.
Then, the water from the mine next door can be drained here.
Yun Fu was afraid that they didn't understand what she meant, so she used a broken clay pot filled with water to demonstrate it to them.
"Now, this clay pot is the mine. We just need to smash a hole in its bottom, and the water inside will flow out."
After she explained it this way, everyone understood.
So here comes the question.
"There's a distance between the two mines, and they're separated by a very hard stone wall. It's impossible to dig!"
"If you can't dig it out, think of other ways."
Yunfu thought that manual digging was too slow.
Once the excavation is completed, the water will rush in suddenly under the pressure, and the digging workers will be in danger.
"How did you trap us in that mine before?"
"It's a mechanism. The stones were originally piled together and supported by a mechanism. Once the mechanism is triggered, the stones fall down."
After hearing their answers, Yun Fu was a little disappointed. She thought they had already been able to make black powder.
There was no other way, Yun Fu could only do it herself.
There was a grenade in her space. Although it was very powerful, it was not suitable for blasting.
The best way now is to get some black powder and use it for targeted blasting.
The key is that this thing is easy to make.
Only three things are needed: sulfur, saltpeter, and charcoal.
She had burned a lot of charcoal before, so she just needed to ask someone to go back and get some.
As for sulfur, she remembered seeing it in the dog emperor's treasury. In the Five Kingdoms, sulfur was also called stone sulfur and was used to treat diseases and make elixirs.
As the Dog Emperor's health deteriorated, he began to seek ways to achieve immortality and became obsessed with alchemy.
The remaining material - saltpeter - is commonly found in the soil in the corners of old houses, especially in the kitchen, because of frequent cooking and a lot of saltpeter precipitation.
Yun Fu went over the idea in her mind, confirmed the feasibility of this matter, and immediately arranged for someone to do it.
The two of them took her letter and went to the ninth district to get charcoal.
Another group of people were arranged to go to several nearby villages to collect soil from the kitchens and corners of old houses.
To be honest, everyone was forced to obey her orders and do this out of fear of her powerful strength.
In fact, no one believed that she could really rescue those people.
"What do you think our new village chief needs so much dirt for? Could he be doing something for a ritual?"
"Let's do it! I hope Tieniu and the others can have a good life in their next life."
"Let's go dig!"
…
The only person who believed in Yun Fu was Qi Hanzhou. Although he couldn't figure out the connection between the mud in the corner and saving people, he knew that his little girl would not joke about matters involving human lives.
Wait until those people bring back baskets of soil.
Yun Fu asked someone to prepare several large iron pots, put the soil directly into the pots, and kept adding water, stirring and boiling. This step lasted for a day and a night. When a layer of white crystals formed on the edge of the iron pots, those white objects were the saltpeter she wanted.
Rescue is about racing against time.
Yun Fu didn't dare to close her eyes. She found an opportunity, entered the space, and took out a few pieces of sulfur from the dog emperor's treasury.
Grind into powder with tools.
Wait for those who go to the ninth area to bring back the charcoal.
She locked herself in the room and prepared the three ingredients in a certain proportion.
To ensure that everything was foolproof, she took the prepared gunpowder to an open space outside and conducted a series of experiments.
"Chief, are you going to start the ritual?"
