Li Shimin and the Kingdom

Looking for Books with a Protagonist as Smart as Li Ziye, Preferably Not Mindless

I'd like books like "Misty Rain Tower".

Flower Angel: The Female Lead Is Xia An'an's Twin Sister

Please, I Want Strong Female Leads Like Manshu and Feng Qian: Cool, Powerful, and Beautiful

Looking for novels like Evil Emperor’s Favorite: The Useless Miss Rules the Nine Heavens and After Awakening the Four Spirits, I Made a Contract with the Entire Divine Beast Squad. No saintly heroines, no saintly heroines, and no dragging plots.
