Chuanxing Shijie Zhi Hua

Xinwen was just a history major student until she’s caught in a fire at the library. Before she passes out, she sees a vision of a woman and then wakes up in a different world. Now she must live as Princess Wenxin Li, the only imperial magic user of the Flower Nation, sent to The United Realms for a political marriage. Treated as an outsider and challenged to use magic that she doesn’t know, she must fend off rivals seeking to bring about her downfall… while also figuring out why the former queen speaks to her in her dreams.
