Suning Ning, the scroll king of the Immortal Sect, was ridiculed for his useless physique. No one knows that he has been practicing hard every day for thirty years, but he actually has a hidden golden finger - he has been cultivating his skills automatically for twenty years. Accidentally rescued the seriously injured demon king Mo Yuan, but was kidnapped and imprisoned in a cave. The two found that their lives were connected, their cultivations attracted each other, and they opened a taboo bond. She slapped the genius in the face, swept the competition, and climbed all the way to the top; he risked his life to protect her, and proudly asked for marriage, just to share the three realms with her. When the fairy rules forbade love, she smashed the old rules with one sword: "Who said that fairies and devils can't get married?" The two powerful forces joined forces to change fate, save each other, and reset the world.
