Possessing a Crow After Death, I Became an Unrivaled Paranormal Immortal

I Only Like Cultivation Stories with Decisive Killing, No Meddling in Others' Affairs, and Few Female Supporting Characters

Looking for something like "Mortal Cultivator Turns to Demonic Cultivation: I'll Climb to the Top One Step at a Time". Ideally, the protagonist is selfish and ruthless, not just toward enemies. If there's something to gain, anyone's fair game. He shouldn't lose his head over women. Keep those cliché plotlines away.
