Content warnings: not a wish-fulfillment novel, not fast-paced, the female lead kills without mercy, and the male lead is undecided (whoever the female lead falls in love with becomes the male lead).
Chu Jing, the top-ranked killer on the bounty list, feels guilty for killing the wrong person. To make amends, she disguises herself as Chu Yiyi, a frail, sickly woman, and stays by Xue Xiaoci's side for ten years, all the while treating him as a stand-in.
To carry out her plan, Chu Yiyi stages her own death and reclaims her true identity.
Her goal is to kill every corrupt official in the land.
What?
There are too many to kill?
Then she'll bring down this filthy dynasty and ascend the throne herself!
Good-looking, very, very good-looking
