He An, an evil cultivator from the left, walks in darkness and uses crooked magic to do righteous things. Although he kills countless people, he becomes a glimmer of light for the weak at the bottom. He takes orders for revenge, cracks evil formations, confronts Feng Shui masters, Daotuo Group and other forces, exposes the dirty power of the powerful and the darkness of the spiritual world, uses ruthless means to repay grievances, and interprets the way of survival that "the soft-hearted will be trampled on, and the cruel-hearted will be free and unrestrained".
