After I Transmigrated into a Book, I Won Over the Black-Hearted Beauty by Transforming

[Fake transmigration into a book + genuine rebirth + heroine with a transformation bug + secret identities + rebellious, innocent-on-the-outside-scheming-on-the-inside nonhuman male lead + a groveling pursuit of his wife] To save the collapsing world inside a book, Zhang Baishui was summoned into the world by the book spirit and transmigrated into the body of a cat. The cat’s owner was none other than the peerlessly wicked black lotus who had caused the world to collapse: Bai Chen. She could stop the disaster only by finding the ultimate reason Bai Chen turned evil. Zhang Baishui: (barely alive.jpg) Great. My heart, which was hanging in suspense, has finally stopped! Winning him over, in progress: Bai Chen (playing along on the surface), inner thoughts: Keep it up and I’ll kill you. Zhang Baishui, who sees right through everything, trembles and throws herself at his leg. Success! Bai Chen (whining and clinging like a pitiful little puppy): Senior Sister, please be gentle with me... Zhang Baishui (breaking down): Get away from me! Keep kissing me and I really will bite you!
