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.
