In the Zhou Dynasty, gods were not objects of worship, but ghouls that parasitized human destiny. The heroine Gu Qingyue, as the only female executioner in the capital, does not have any system or portable space. Her only reliance is the Gu family's ancestral "Jie Niu Dao Technique" - a mortal martial arts that can accurately see through all the points where spiritual power flows.
When the imperial court asked Gu Qingyue to execute a human hero in order to please the so-called "immortal envoy from the upper world", she cut off the immortal envoy's dharma image in public with a sword. She discovered that the so-called immortals were just high-level monks who practiced evil arts. As long as the sword was fast enough and the heart was ruthless enough, even iron could kill gods. The main plot revolves around how Gu Qingyue used the execution platform, a special "place of cause and effect", to use mortal wisdom and extreme anatomical skills to dismantle and hunt down one by one those "immortals and Buddhas" who regard mortals as nothing without spiritual roots, and finally return power to humans and rebuild the order of the world.
