The heroine was born with a "Nine Yin Ji Evil" constitution (a top-notch furnace). Once her breath is revealed, she will be eaten by monks all over the world. In order to survive, she mutilated her voice and pretended to be mute. Through calculation, she became the knife-sharpening slave of the executioner of the "God-Slaying Division" who specializes in killing monks and is full of evil spirits. The heroine doesn't have a golden finger, so she relies entirely on observing people's emotions, using the residual evil energy from the hero's killing of the demon queen to cover up her physical condition, and secretly memorizing the broken martial arts fragments while the hero is cleaning up the stolen goods.
The two were together in the God-Slaying Platform full of blood and killing, and developed a morbid attachment. The male protagonist is cold on the outside and hot on the inside. He regards the female protagonist as the only pure land, but he does not know that the female protagonist is always ready to escape. In the middle period, the identity of the heroine is exposed, which leads to the pursuit of the entire cultivator world. The male protagonist has to become the enemy of the heroine in order to protect the right path. In fact, he is secretly guarding the heroine, causing the two to hurt each other. In the later period, the heroine understood the evil method of "using one's body to evil" in a desperate situation. She no longer made a furnace, but instead devoured all things. Finally, she confronted the male protagonist who had already been possessed by the devil on the God-killing Platform, completing the reversal from prey to hunter. This sword cut off the past and reshaped the order of the immortal world.
