After I Transmigrated into a Book, the Cold Palace Cannon Fodder Became a Lucky Treasure

Transmigrate into a book + System + Inner thoughts + Not a strong female lead. If you can't accept that, leave, leave, leave.

A father-daughter relationship. Whether the heroine will return to the real world in the end is undecided. Ji Mo exists only in the world of the book.

A diagnosis notice from the hospital lets Qin Yan see her boyfriend's true colors. Perhaps Heaven couldn't stand it anymore.

Just before she dies, she accidentally triggers a System to save the villains. The System tells her she can only succeed by stopping the villainous fathers from destroying the world of the book.

She must raise their affection levels to one hundred to truly succeed.

She needs to reach one thousand to return to the real world. The System's rewards include a healthy body and a mysterious grand prize. But gradually, Qin Yan no longer wants to go back. So what is it that has captured her heart???
