Conquest of the Perfect Heroine

Chu Nanle had just won the lottery, but before she could enjoy it, she transmigrated into a novel she had once rescued from the trash to use as a wobbly table leg. The resentful book spirit made her the most idiotic heroine in the story:

Obsessed with the male lead, she gets her parents killed, brings about the complete destruction of Kunlun, and leaves the cultivation world's strongest master gravely injured, giving the demons an opening to invade the continent and kill millions of people???

Chu Nanle doesn't understand. “If I've already done every awful thing there is, why bring me here?”

The book spirit says, “You're the reason the heroine in my book went so badly off the rails!”

Chu Nanle looks at her protagonist's halo, which is about to go out. “...You didn't have to offer me up to the sword the moment I got here!”
