Mortal cultivation + an ordinary man’s rise to greatness (no harem, no brainless characters, not a wish-fulfillment story, no System, cultivation in another world without transmigration, no technology)
What could be more carefree than becoming an immortal? How can you become an immortal without going mad? What could be greater than eternal life? Power? You bring nothing into this world and take nothing with you when you die. Love? After a hundred years, even the most beautiful will be gone. The line between becoming an immortal and becoming a demon lies in a single thought.
