Chu Lingyao transmigrates into a book, becoming the villain's beloved white moonlight in a novel she read before bed. In the original story, her character doesn't live past twenty-five. She's a supporting female character whose role is to motivate the villain to build his career.
Other people transmigrate into books with a System to help them turn their lives around and become the protagonist. But Chu Lingyao has no help after transmigrating. Well, at least she won't get System alerts telling her she's acting out of character.
The original story: A powerful cultivator in the cultivation world is reborn, but at the worst possible time. There are villains rising on one side, prodigies on another, Systems on the left, transmigrators on the right, Heaven above, and the Ghost Emperor below...
Rebirth protagonist Ling Feng: Hold on! So after I'm reborn, I still have to get bullied by all these big shots?
Villain protagonist Zhan Xiuji: Just don't cause trouble.
Prodigy Feng Yimu: Big Brother is right.
Sect Leader Ji Xuanqing, who has a sect-management System: Um... I just want to make the sect my father left me a little bigger. I don't want to cause trouble, so I hope all you big shots can get along...
Transmigrator Bai Li: Uh... I'm just an ordinary person. I only ended up in this cultivation world by chance...
Heaven (Di Hongyuan): Sigh... Little Brother Ling Feng, this isn't the cultivation world it used to be. These days, the place is full of people with cheat abilities.
Ghost Emperor (Ming Ze): You're lucky if you don't cross me!
