Lu Yun, the chief disciple of the Guiyuan Sect, descends the mountain carrying a marriage contract, only to face an enormous debt and an even greater conspiracy. Refusing to rely on his fiancée to turn his fortunes around, he puts aside his supernatural powers, dives into city life to work and earn money, and honestly repays the debt. Everything changes when the Blood Fiend Sect appears. To protect those around him from harm and uncover the secrets connecting the Blood Fiend Sect and the Guiyuan Sect, Lu Yun works tirelessly to make a living by day and guards his loved ones by night. He exposes scams, upholds justice, and navigates one dangerous turning point after another. As the Blood Fiend Sect closes in, he stages a comeback and unravels one scheme after another, ultimately turning the tide and restoring his sect to glory.
