Transmigrated Into a Book as a Cannon-Fodder Girl: The System Wants Me to Rewrite the Ending

Billions in supplies + drought + no canon pairing + no contrived drama + some political intrigue

The heroine is just a young woman who grew up safe in modern society. The hero also spent five years out of the picture, and he's no inhuman genius.

Yuan Zhiqing, whose combat ability is maxed out, gets into a car accident during a mission. When she wakes up, she's transmigrated into a book set in a year of disaster. The System lets her choose how the story goes, so Yuan Zhiqing decides to turn a male-oriented story into a female-oriented one!

Natural and man-made disasters strike all at once, and the people suffer one calamity after another. She decides to have the former Crown Prince's younger brother overthrow the foolish emperor and return to court!

A genius imperial younger sister who lost her family at birth and is frail and sickly? She'll learn medicine and martial arts, every bit of it!

I'll decide how it ends anyway, so who cares what happens along the way?

I'm the one in charge of my world!

Go, go, go!!!
