- Description from Novelupdates

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

Nanzhi only thought she had traveled into a novel about raising a child. Relying on her many years of “Wilderness Survival” watching experience, she hunts rabbits up the mountain for grilling every day, gropes for fish in the river to make soup, and diligently raises the child. Just when she thought her life was finally looking up and she could have her “second spring”, the “husband” who was rumored to have died hundreds of times suddenly appeared. Wait a second!She seems to have ended up in a novel where the male lead is the main character!Nanzhi? Isn't that the cannon fodder and deposed wife?PS: Not a web novel about farming, the female lead doesn't have a golden finger space system. Just turned eighteen and got into university, not a novel about a powerful female protagonist.
