For Frieren, this is also a two-way learning process.
After all, her world and the modern world are so different that she doesn't recognize a lot of things. Liliath and Mary need to teach her slowly, but as a Great Demon Mage, Frieren has a very sharp mind. Without spending much effort, she quickly figured out the uses of many things.
For example, a TV is a device for watching things happening from afar, a mobile phone is a device for contacting others anytime and anywhere, etc...
But for Frieren, this obviously wasn't enough, so next she had more questions.
"Since the people of this world don't have magic, how did they create these things?"
"Well..."
Faced with Frieren's very natural inquiry, Liliath, Naruse Mio, and Mary were dumbfounded. They only knew how to use these things, but as for the principles... they didn't understand either!
So Frieren went to find Duanmu Huai, and as expected, Duanmu Huai didn't understand either.
