Dreaming of the Starry River: the Adventures of the Palace Bride

I'm Begging for a Book About Palace Expedition. I Don't Want a Heroine Who Is Too Cheerful and Lively. Please.

I want to read a book similar to "[Yunzhiyu] Zhengzhiyuan". The heroine should not be a mind reader, she should be a brainless person, she should have some sense of perspective, and she should not have any superpowers or golden fingers. It's fine if she is the only one favored by the palace, but the heroine should not be brainless and don't make any mistakes. Thank you~
