The core appeal: she doesn't overwhelm her foes with spiritual power; she makes them answer for their karma. White lotuses, unscrupulous relatives, fake masters, ruthless tycoons, and scumbag men can't hide an ounce of their darkness from her.

The heroine makes money, takes on disciples, exposes scams, and fosters good karma, thriving wherever she goes.
