Disaster in the Wilderness: Find a Husband to Survive

On a desert island with nothing, men and women mainly make their own tools, build houses, collect, make food, and fight monsters. (It's like going back to the Stone Age) The male and female protagonists have modern knowledge and systematic help, and their lives are pretty good. When teaching survival skills, the main thing is to describe food [laughs]

When I read Chapter 60, the heroine was not curious about where this desert island is? Why don't you ask the system if it's possible to get out? Furthermore, who is the heroine, what kind of job does she have, what is her family background, and why does she fly? Who does the male protagonist do and what is his family background? Aren't two people curious about these when chatting with the female protagonist? The plot and rhythm of the book are pretty good, but I just can't get into it.
