My Cultivation Art Has Turned Dark

The Protagonist Creates His Own Cultivation Techniques, Works Behind the Scenes, and Raises the World to a Higher Dimension Without Ascending

Looking for Urban Supernatural Novels Where the Protagonist Is the Only One with Supernatural Powers, No Martial Arts or Special Abilities

Are there any stories where someone cultivates immortality and shows off their powers in front of others, or where a deity reveals their power to the public? I want the only supernatural being in the modern world to be the protagonist. Everyone else should be ordinary, with no ancient martial arts or people with special abilities.

Looking for Cultivation Techniques

Something fairly popular.
