The alchemy genius Yu Xiaoman and the sword cultivator's mortal enemy Jiang Linyuan were forced to live together and play each other due to the exchange of souls during a thunderstorm. From the betrayal of the natal sword to the CP addiction of the whole school, the two of them gradually discovered that the oath of "life and death" five years ago had already laid the foundation of their love through hilarious events such as the bombing of the alchemy furnace, the princess embracing the poisonous swamp, and the love charm. They eventually advanced from happy enemies to model Taoist couples in the world of cultivation.
