I walked out of the shelter and took a piece of saltpeter and returned to the shelter. As a result, I just saw the black spot touching the mineral resource detector!

[Detecting the depth of minerals is in progress …]
[completed]
【 The burial depth of saltpeter mine is 3m-71m 】
[The buried depth of gypsum mine is 2m-71m]
[The buried depth of the gold mine is 4m-11m]
Lin Yue? ? ?
And this function?
No, how to press this function for black spots? Meng?
Lin Yue looked at the screen for a while with doubts and then suddenly rushed outward.
He went all the way to a robot dog in the square mine and reprogrammed it.
"Set to dig to the meter and then …"
Soon after he finished setting, the robot dog was restarted and his foot was chiseled at this saltpeter.
After Lin Yue set three heads in a row, these three heads followed to dig.
He then found two transport robot dogs and specially set up a program for them to meet these four robot dogs. After that, he quietly watched the little guys dig constantly.
After more than ten minutes, a whole stone with a little golden light was dug up and taken to the surface by the handling robot dog, and one stone after another was piled up continuously!
There is!
Boy, it’s no wonder that I’ve never seen anything except saltpeter and gypsum stones before. It turned out to be a matter of burial depth!
"But this is not a gold nugget but an ore." Lin Yue carefully observed a piece of gold ore and finally calmly saw the problem after the excitement passed.
This is not pure gold, but contains "gold" ore.
If it is not smelt, it will eventually be as profitable as it is now.
"There seems to be something that must be opened quickly."
Lin Yue thought of the melting furnace, a large-scale machinery that has been occupying the place but failed to emit light and heat in the shelter!
The failure of the smelting furnace to be transported is also due to the lack of fuel for transportation.
Coal is no good, let alone wood.
We must use better fuel.
He remembered that the best fuel for the smelting furnace was either "diesel oil" or "heavy oil"
Although it is not clear whether the original earth melting furnace is like this, what he has now is actually diesel and heavy oil.
He did have some diesel oil, which was exchanged from Xing Lingfeng, but the quantity was not much. But there was no place to find "heavy oil".
And now it’s different.
The oil river base is just right, and it will produce a lot of resources such as gasoline and diesel every day!
Ore has a melting furnace, fuel and so on.
"It seems that the next thing to do seems very simple?"
Lin Yue feels.
This time it seems that he has finally taken the right first step in ore smelting!
And then …
He thought of ilmenite stone that kept falling ash.
