True Mastery
The inclusion of the Labyrinth missions means that the labyrinth itself is something that will have to be explored in the future. And to make sure that happens, a farmer has to keep it running while keeping the farm afloat. Despite being excited, Elaina is also worried about this one.

"So I am going to fulfill that job that was now handed to me after inheriting the farm after I gave birth? I didn't know that was a requirement," Elaina scratches her head.
"[At first, this was indeed not a requirement but an optional thing. Even now, it is still optional and you can choose to ignore it and you won't be forced to do it. But you will be most rewarded if you decide to accept and do it. But you will not be punished from not doing it, aside from missing those rewards entirely.]"
