From a Stone to Unrivaled Under Heaven

A Rogue Cultivator Who Finds an Inheritance, Has No Backing, Competes for Resources to Cultivate, and Joins No Faction

The protagonist inherits a legacy, has no background, and joins no faction. They steal resources, including from powerful sects, then run after every fight and every robbery. Once they're stronger, they come back to steal more. Basically, they go it alone and have very few friends. Something along those lines.
