After I Transmigrated Into a Book, I Used the System to Save My Mortal Enemy

[Strong Female Lead] [Fantasy Cultivation] [Ensemble Cast] [Villainess Makes a Comeback] [No Romance]

After transmigrating into a book, Ye Qingyue repeatedly switches sides within the villain faction. She becomes the love rival and undercover agent of the heroine, the beacon of the righteous path, and even comes with a System golden finger.

She acts as the male lead's lackey while constantly snatching away his resources.

Just as the original heroine is about to be deceived into giving her body and heart to the male lead, who plans to refine her Dao fruit, Ye Qingyue immediately steps in and saves her, then turns around and informs the male lead of her whereabouts.

The heroine's younger brother grabs her by the collar and roars, "Why do you keep switching sides? Don't tell me you're secretly in love with my sister!"

She coolly denies it on the outside, while internally screaming: Silly boy, your sister is the key to saving the world!

The villainous male lead sneers from the shadows. "My dear undercover agent, you're so committed to your act. Do you really think I can't see through you?"

The System's warning flashes frantically: "Warning! Countdown to the male lead merging with a foreign soul..."

Ye Qingyue whips out the plane bomb she's been hiding. "Then let's flip the table together and see who goes down first!"
