Zuan looked around and found that there were huge wooden booms everywhere, similar to the cranes he had seen on construction sites in his previous life.
"These are all products developed by the academy. They can lift heavy objects from wells or low places, and they are very practical." Yu Yanluo introduced him as if she were introducing her own business, with a proud expression.
Zuan remarked with emotion, "The academy's research can be far more helpful to ordinary people than the cultivation practitioners themselves."
As he continued walking, he suddenly noticed two familiar objects with some handcarts on them, and he could vaguely see some ore inside the carts.
Yu Yanluo explained, "The Yu family's mines are not just for mining elemental stones; they also contain many common mineral deposits, such as iron ore and copper ore."
"No, you actually have railway tracks here?" Zuan was more interested in something else, pointing at the two tracks on the ground with great surprise.
"This was invented by a miner to help transport these mine carts. We found it very useful, so we promoted it extensively in the mining area," Yu Yanluo replied.
"Where is that miner now?" Zuan asked curiously, wondering if he was also a time traveler.
"It seems he was accidentally killed in a mining accident later on." Yu Yanluo said sadly, "No matter how many safety measures are taken, mining accidents still happen from time to time. So these ores are dug out by the blood and sweat of countless miners. It's just a pity that those big shots in the halls of power don't care about these things."
Zuan remained silent. In truth, it's not just this world; which world isn't like this?
It's a pity that the miner who invented the rails might have invented even more useful things if he hadn't died.
If he's a time traveler, he's really unlucky.
Continuing forward, the two stopped. Zu An stared at the enormous pit before him, speechless: "This is the Yu family's mine?"
This giant pit spans several thousand meters in circumference, with winding roads carved into its walls, demonstrating the immense scale of the engineering work that took place there.
The bottom of the giant pit was pitch black. Even with Zaun's current eyesight, he couldn't see what was inside. It looked like the mouth of a giant beast waiting for its prey to come to its door.
“That’s right. The mines are all underground, and the roads inside are interconnected. Don’t wander off. Every year, quite a few experienced miners get lost and disappear inside,” Yu Yanluo replied.
Zuan nodded: "Even if Xiao Yao catches up now, we don't need to worry."
"Come with me." Yu Yanluo lightly touched the ground with her toes and, instead of following the workers' paths along the cave wall, jumped directly down.
However, she would land on the mountainside every now and then to rest, and dared not jump straight into the dark hole below.
Zuan also jumped down. As they descended, the surrounding light grew dimmer and dimmer until it was almost pitch black.
At this moment, Yu Yanluo came to his side and whispered, "You can't have open flames in the mine, so don't use a tinderbox."
As she spoke, she took out a luminous pearl, its soft light shining on her body, making her skin appear even more delicate and beautiful.
Zuan smiled and said, "I know. There are definitely all kinds of flammable gases in the mine. They would explode if exposed to an open flame."
No sooner had he finished speaking than a chilling, inexplicable roar suddenly echoed from the depths of the mine, followed by a violent tremor throughout the entire mine.
