Duke An suddenly remembered last year's rumors about railway use, "At this time last year, it was widely rumored in the capital the many benefits of using railways to transport materials. It seems that the first to use railways was the Qi family's construction industry, the same Qi family you are with, right?"
Ye Xinyan nodded hastily, "Yes, that's why His Highness Prince Yu found me to help him operate the railway carriage. That's also why I dared to agree."
These were also things Duke An had not quite understood, "But in just two short years, you've been able to learn so much? You've even mastered machinery and construction?"
"Mastered? Not at all," Ye Xinyan explained, pushing the hastily sketched diagram of the railway operation she had done earlier towards Duke An, "As you can see, I can only do these things. Those tasks requiring superb craftsmanship are all done by Grandfather Qi and Wong Qiao."
