I Transmigrated into a Book to Save the Dark Moonlight: The Princess and I Join Forces to Slay the Dragon

The rating just came out! [Two female leads + Transmigrate into a book + System + Disguised as a man + Redemption + One-on-one romance + Both devoted to each other] Xie Zhaoning had spent years surviving in the apocalypse. One day, an enemy ambushed her and killed her, and somehow she transmigrated into a book. Xie Zhaoning had only just opened her eyes... System: Ding! Host has been bound to the Corruption Redemption System. Xie Zhaoning: I’m corrupted myself, and you want me to save someone else? That’s hilarious--- System: Warning! Warning! Xiao Ruoheng’s corruption level is about to reach 100. If this world collapses, Host will vanish along with it. Current corruption level: 85, 86, 90, 95--mission failure imminent!!! So startled that she sprang up like a carp, Xie Zhaoning declared, “How could I be the sort to fear a challenge!” She immediately scampered off to find Xiao Ruoheng. There was no way she’d let Xiao Ruoheng turn evil. She had to make her purer than someone with vitiligo. Just as Xiao Ruoheng was being humiliated by others, her resentment swelling, and she was about to become the Big Bad and destroy the whole world, someone appeared... “I hear there are ghosts in the palace and the outskirts.” “Those aren’t ghosts. They’re the wronged spirit of Consort Jing, unable to rest in peace.” Rumors were running rampant in the capital. To put a stop to them, the emperor had no choice but to bring Xiao Ruoheng back into the palace. System: Congratulations, Host! You have successfully lowered the corruption level. You have been awarded points and unlocked your past-life ability to teleport. From then on, her strength skyrocketed. She killed anyone who stood in her way, be they god or Buddha. But life is full of surprises, and there seemed to be something a little off about Xiao Ruoheng. Xie Zhaoning: “Yamete, yamete! This isn’t right--” Xiao Ruoheng: “Xie Zhaoning, come here...” Xie Zhaoning: “Okay.”
