Mo Lan remained silent for a moment, allowing her mind to calm down. She reached out and pinched the black charcoal ball on the ground, confirming once again that she hadn't misread it.
This is a somewhat weathered lump of coal!
The only thing that puzzled her was that coal is buried deep underground, so how could something like this appear on the surface?
Mo Lan stood in the valley, looking at the surrounding terrain. When she first stood there, she thought the valley was like a basin. Now, looking around, all she could see were towering peaks and tall, dense trees, which made the terrain here look even more like a courtyard.
Could it be that changes in the Earth's crust here have brought the coal, which was originally buried deep underground, to the surface?
While pondering, Mo Lan carefully explored the surrounding area, picking up some chunks of coal as she went. She became increasingly convinced of her guess that the earth's crust must have changed in this mountain valley in the past few years.
However, for Mo Lan, there was only surprise; she just didn't know how thick the coal seams were or how vast the area was.
He then arranged for people to come and mine coal, and before winter arrived, he made sure the village had enough firewood for heating.
Thinking of this, Mo Lan was once again grateful that she had come to a time of war and chaos, where the land had no fixed rulers and belonged to whoever had the strongest fist and the greatest ability.
She discovered this place, and the initiative is in her own hands. Developing coal resources to benefit future generations... oh no, it's definitely possible to benefit the elderly, weak, women, and children of Qinglong Village.
After deciding on her plan, Mo Lan took out a shovel from the mandala and dug around in a random spot. At a depth of one meter, she could see the black coal. The deeper she dug, the better the color and the higher the quality of the coal.
After filling some containers with datura, Mo Lan wiped her hands and sat down on a nearby rock to rest for a while.
"Tomb Spirit, do I have an excavator among my collection of Sinotruk trucks?"
"...Yes, there are several large Jiefang trucks, eight-wheelers." The tomb spirit paused, then couldn't help but remind him, "But boss, although you have some stuff, it burns gas."
Mo Lan: "..."
I almost forgot, these are all oil-drinking creatures.
There isn't enough storage space.
"Boss, you could build a slide, using the principle of a roller coaster, to transport the coal out. That way, you can solve the problem by burning coal."
Using locally sourced materials and the machinery stored within the mandala, the experiment wasn't too difficult.
What's more, the eldest sister is not only a science major, but also an expert in mechanical manufacturing.
If it weren't for the unexpected journey to Somalia, it might have been recorded in the history of Chinese civilization.
roller coaster?
Does it utilize the principles of steam locomotives?
Mo Lan stroked the pointer in her hand, the principle of a power train flashing through her mind.
The engine of a steam locomotive is actually a coal-fired steam boiler. The combustion of coal turns water into high-pressure, high-temperature steam, which is then sprayed into the engine cylinder to push the piston. The piston then drives other mechanical components to propel the wheels forward.
With a slight modification to this principle, the wheel power is changed to upper pulley power, imitating the old-fashioned tram, which is more suitable for uneven mountainous terrain.
With a goal in mind, Mo Lan stopped dawdling and returned the way she came. She quickly washed herself by the stream before heading towards the campsite.
As soon as they reached the cave entrance, they heard intermittent wails coming from inside.
"Captain, are you sure you don't want to kill us?"
"I don't even do this much labor in a year. Now, every part of my body aches."
