Transmigrating as the Younger Sister of a Bigshot with Multiple Identities - Chapter 17

A prestigious senior mechanical engineer in the industry, Xu Yi was sent to a world dominated by magic.

In a world with an almost non-existent industrial system, how can Xu Yi display his value?

When magic collides with modern technology, when magic merges with machinery, that is the beginning of this story.

Urano, a bookworm who had finally found a job as a librarian at a university, was sadly killed shortly after graduating from college. She was reborn as the daughter of a soldier in a world where the literacy rate is low and books were scarce. No matter how much she wanted to read, there were no books around. What is a bookworm to do without any books? Make them, of course. Her goal is to become a librarian! So that she may once again live surrounded by books, she must start by making them herself.

Okay, so I know I applied to become a caretaker, but I didn't sign up for having to experience all these crazy things! I'm just a simple guy!

I was reborn into a chaebol family.Into a time with no cryptocurrency, no internet, and nothing else.
