Looking for Murim / Wuxia novels with a dark ruthless MC

I’m looking for Murim / wuxia web novels where the MC is dark, ruthless, and feared — not a typical righteous hero.

I really enjoy stories where the MC is like a Heavenly Demon type, cold and willing to kill if necessary.

Some novels I really liked:

•	Reaper of the Drifting Moon — assassin-type MC with a very cold personality.  

•	Murim Psychopath

•	Lord of the Truth

What I’m looking for:

•	Ruthless / psychopath / demonic MC

•	Murim or wuxia setting

•	 survival story

•	Smart or manipulative protagonist

•	MC who doesn’t hesitate to kill enemies
