The Self-Help Guru of the Supernatural World

I'm the protagonist, so I can't get cocky. I'll keep my head down for now. No matter what, I need to drink the strongest liquor, set my sights on thousands of beautiful women, and make friends with rich, handsome guys. That's the blissful life a Sword Immortal ought to have. If rich, handsome guys aren't your type, don't worry. Just go find a self-made rich man instead. Live for eighty or a hundred years, and you'll be the rich, handsome elder yourself!
