As the title says, please recommend me a xianxia novel with a unique mc, so far the ones i liked were the main characters of :-

I Shall Seal The Heavens (freaking loved him)
Sovereign of the Three Realms (same, he has grown on me)
Ze tian Ji ( loved his noble aura, reminded me Rai from Noblesse)

If you know a light novel that isn't xianxia, i am ok with it as well.

Thanks in advance.

Heavenly Jewel Change (Novel) A shameless MC and plays around a lot. You can call him a rascal. It's pretty good though it starts off with the usual xianxia tropes
Warning:

There is a rape scene near the beginning of the story

True Martial World (Novel) What of my favs, up there with ISSTH, the MC isn't the usual ruthless person, great story telling. It can be a slightly slow at the beginning but worth it.
Yishi Xiejun (Novel) I somewhat get the same feeling of Sovereign of the Three Realms from this one.
I havn't read this but you might want to take a look at it
World of Cultivation (Novel)

Anything written by Fenglin tianxia, including otherworldly evil monarch, Transcending the 9heaven, realms in firmament.
