Apocalyptic Female Supporting Character: Boss, Please Step Aside

Ye Ranran transmigrated into a book! She transmigrated into a book where she skipped around but happened to see a vicious female supporting character who deliberately caused trouble for the female lead and was eventually wiped out by the female lead!

Ye Ranran: ...

She said she's not bad, please don't mistreat her!

In order to survive in the apocalypse, she worked hard to upgrade and stockpile resources, avoiding competition and fighting, remaining quiet and unassuming. But at some point, the plot started to go awry...

But the apocalyptic scenario she imagined wasn't so simple...

In short, the female lead works hard to level up and defeat monsters, and incidentally snags a powerful guy along the way.
