Sword Nine Seeks the Flowers

Any Wuxia Novels with a Powerful Male Lead and a Princess as the Female Lead?

Strong Logic, a Sharp-Tongued, Emotionally Intelligent Protagonist, and No Predictable Plot

I'm looking for highly rated, long or completed novels with a humorous tone. I want to be able to switch my brain off while reading, but the author should keep theirs switched on. Either a male or female lead is fine. I want airtight logic, high emotional intelligence, and good banter. The plot shouldn't be easy to predict, and the prose shouldn't feel stiff.
