Gu Siyu, a disciple of the Xiaoyao Sect, is proficient in fortune-telling, medicine, and Feng Shui. Quirky and empathetic, she faces a deadly 'Birthday Calamity' at the age of 24. The only way to survive this heavenly trial is to find and marry a man with a specific 'pure-body' constitution, or else she will perish. On her master's orders, she descends from the mountains to search for her fated man.
