Can you recommend some of the works of the black-bellied evil male protagonists in ancient novels?

Requirements:
1. The male lead must be black-bellied and devilish
2. The Female Lead Must Be Very Smart
3 It's best to have a battle of wits and courage between the male and female leads
4 The author's writing style must be good, and he definitely didn't want the kind that was like Xiao Bai's!
5 If the ending is good, you can abuse her a little, but not too much.

Are there any other books? The more black-bellied the male and female protagonists are, the better
