"Hello, everyone, ahead is Yanshi Mountain."
The pretty tour guide transmitted her sweet voice to each tourist through a wireless connection.
"Why is it called Yanshi Mountain? It's because the ruins of a Mechanical Civilization were discovered here. Yanshi is the first documented mechanical master in ancient times who created robots..."
The tour guide gestured toward Yanshi Mountain outside the car window, introducing energetically, "Yanshi Mountain is three thousand meters high, not a blade of grass grows on it, making it look like an iron mountain from afar. Thus, it is also known as Iron Mountain. The ancient Mechanical Civilization ruins are inside Yanshi Mountain, with a complex architecture resembling a maze."
