Shen Wei E Yi Nü Pei De Wo Yang Cheng Bingjiao Nüzhu Hen Zhengchang Ba?!

Jiang Yang is a game artist out gathering material for the game she was working on when she fell off a cliff and transmigrated into a world of immortal cultivation. She diligently cultivated her way to immortality, and she was about to ascend and return to her own world when a mysterious glitch caused her to transmigrate again, this time into a world of magic (like the start of an otome game). She met the main heroine, who was being bullied by the villainess at the Magic Academy, and that was when Jiang Yang realized that this is the world of the game she was working on? Now her fate is tied to Xin Lu, the heroine of the game. Jiang Yang thought that if she just beat the game, she can finally return home. But as the story progressed, she remembered all the over-the-top plotlines made up by the lousy writers, and she can't stand seeing Xin Lu suffer through it anymore. So she steps in and helps Xin Lu reject the playboy prince, teaches her cultivation techniques to fight off the bullies, and even seduces Xin Lu herself! As they become more intimate with each other, Jiang Yang starts to realize that her fate might intertwine with Xin Lu more than she realized…
