On the day he was offered as a sacrifice to the ancient beast, Ling Shuang thought he was dead. Unexpectedly, the blood of that ferocious beast would become the key to her unique talent. Overnight, the good-for-nothing disciple who could be bullied by everyone became the chosen devil who possesses the supreme sword and specializes in sucking evil spirits. Being chased by the Immortal Sect? Then she would trample the fairy gate under her feet. Scorned by the world? Then she will make everyone in the world shut up. Ling Shuang held a three-foot green sword in her hand and smiled boldly: "Don't say it's a devil. I'm going to poke a hole in the sky today. Who dares to stop me?" There was a sanctimonious hypocrite senior brother in front of him who was eyeing him, and behind him an old enemy who loved to play Bai Lian was stalking him. Ling Shuang expressed that he was a little annoyed. It doesn't matter, if one sword doesn't work, then use another sword. There will always be one sword that can shut them all up. This is a hilarious and heart-warming story about going from a sacrifice to a demon king, killing blood all the way, and gaining a loyal dog(?) Senior brother at the same time.
