Che Jianyi didn't know what coal Duan Wenjun was talking about.
However, according to Duan Wenjun's description, he thought of something.
One of his distant relatives lives in Yunzhou, the northernmost part of Dashun.
Behind his relative's house is a mountain.
Most people know that the mountains in the north are mostly jagged with rocks, overgrown with weeds, and without any big trees.
However, the mountain behind his relatives was full of large trees and very lush, which was considered a peculiar existence in the area.
It is also because of this that many locals think it is a geomantic treasure land.
About twenty years ago, a wealthy local family bribed the government, surrounded the hilltop, took it for their own use, and moved their ancestral graves there.
At that time, when a wealthy family was making graves, they even asked his relatives to help.
It is said that when the foundation was dug to build the tomb, the soil below the mountain was discovered to be black after digging less than a few feet deep.
Not only the soil, but also the stones are black.
The local people spread the news even more miraculously.
I just didn't expect that on the second day after the wealthy family moved their ancestral graves into the mountains, something big happened.
The next morning, the weather changed.
The sun was shining brightly, but suddenly it became dark, with dark clouds and lightning and thunder.
A bolt of lightning struck a big tree on the mountain, causing a mountain fire.
The wealthy family wanted to organize people to put out the fire, but unexpectedly the mountain fire did not last long before it was extinguished.
Because, a heavy rain came down and extinguished all the open fires.
They thought the matter was over, but unexpectedly, strange things happened next.
When the rain stopped, the entire mountaintop was wrapped in a thick mist, and the heat wave was so intense that people couldn't get close at all.
And, that's not the scariest thing.
The most terrifying thing is that after a heavy rain, the mountain fire that was originally extinguished actually started burning again.
Moreover, this time it was not a small area that was on fire, but black smoke and flames began to rise across the entire mountain.
Che Jianyi's relative lived at the foot of the mountain, so he saw the whole process very clearly.
It was also because of the fire that they had to move.
In the end, he took his whole family to join Che Jianyi's father.
Because, after the fire, the mountain suddenly became bare.
Moreover, many places on the mountain suddenly turned gray.
Later, whenever there is a heavy rain, the soil will be washed down from the mountain with the rain, which is very dangerous.
The ancestral grave of that wealthy family, the coffins and bones inside were naturally reduced to ashes.
This incident caused quite a stir locally.
Many people said that the wealthy family was unkind and angered God, so they were punished like this.
Some people also say that they moved their ancestral graves into the mountains and destroyed the original feng shui of the mountains, which is why they suffered this disaster.
Back then, Che Jianyi was not very old, so he just listened to it as a ghost story.
His father often used this incident to educate him and let him be kind to others.
After so many years, this matter almost slowly faded out of Che Jianyi's mind.
Hearing Duan Wenjun mention coal at this moment, he suddenly understood.
Perhaps those black soil and stones are the coal Duan Wenjun mentioned.
Moreover, since Duan Wenjun said that using coal as fuel would result in a higher concentration of temperature, it can easily explain the resurgence of dense fog and trees on the mountain at that time.
If the mountain is full of coal, even if it rains heavily, it will only reach the surface of the mountain and cannot extinguish the coal burning below.
Once the rain passes and the fire ignites again, it will be normal.
Che Jianyi's analysis immediately impressed Duan Wenjun.
It's rare that he can have such a sharp mind.
However, when he heard from Che Jianyi that Yunzhou, where his relatives lived, was thousands of miles away from Wangjiang County, he couldn't help but give up the idea of mining coal there.
Even if what Che Jianyi said was really coal, the day lilies were already cold when they were transported from Yunzhou.
Although the coal could not be used for the time being, Duan Wenjun asked him about the whereabouts of this relative.
After all, his relative had seen what coal looked like with his own eyes. Duan Wenjun wanted Che Jianyi to write a letter asking for his help to see if he could find coal in the south.
Of course, the costs involved are naturally not a problem and will all be borne by Duan Wenjun.
Che Jianyi immediately patted his chest and assured that there would be no problem, saying that if Duan Wenjun needed it, he could ask his younger brother to go over and invite the relative over.
Duan Wenjun was overjoyed when he heard this, and immediately gave Che Jianyi five taels of silver to help his brother and relatives on the road, so that his brother could welcome them back as soon as possible.
While Duan Wenjun and Che Jianyi were talking, Zhao Xiaoliu was already busy with everyone, and the process of molten iron mold casting was basically completed.
"Young Master, there is something I don't understand." At this moment, Ma Xinyuan, who had been silent, suddenly spoke, "Since we have used this new furnace built by Master Che, we can better remove impurities from the iron ore. By making the molten iron purer, the iron we smelt should be better. But why do we need to add these carbon powders to it?"
This problem has been in Ma Xinyuan's mind since Duan Wenjun gave everyone a rough explanation of the carburizing method for forging.
However, although he had some doubts about Duan Wenjun's method, he did not say it out loud.
After all, in his heart, Duan Wenjun's words existed like an imperial edict, and he did not dare to refute them.
Hearing Ma Xinyuan's question, Duan Wenjun suddenly showed a bright smile on his face, "Old Ma, I've been waiting for your question for a long time."
After saying that, he reached out and patted Ma Xinyuan's shoulder, "Old Ma, I feel that since we came back from the mountains this time, you and I have become unfamiliar. I remember the first few days when you came to Duanjiabao, but you said nothing. I will never be secretive or hesitant."
"I know that now that you are a father, you have a lot of worries in your heart." Duan Wenjun sighed softly. "So, you are a little unable to let go, you are even a little worried about gains and losses, and you are a little afraid of losing your current life. This is also normal. .”
"But, I still say the same thing. I, Duan Wenjun, like you, Lao Ma, and naturally I also like your character of saying whatever you want. So, you really don't have to worry about him. We will work hard together. I am I won’t treat you badly.”
"The blacksmith shop on the mountain has a completely different role than the blacksmith shop down the mountain. We need to research and create something new, so the discussion between us will become more important."
"Maybe I can tell you some new technologies that you have never been exposed to before, but I can only know some general directions and cannot provide too many details."
"Whether it's smelting or forging, I'm not as professional as you. The people here are all masters. I can tell you the methods and principles, but how to make what I say come true requires your support. "
"So, whether it is you, Xiao Liuzi or other masters, if you have doubts in your heart, you must speak up as soon as possible. Only in this way can we all play the maximum role with the same thinking and achieve the goal. Best research results."
When Ma Xinyuan heard this, his face suddenly became extremely solemn, "Young master, Ma Xinyuan knows that he is wrong!"
Not only Ma Xinyuan, but also Che Jianyi next to him was also moved.
