Yan Lü, a senior auditor from the Heavenly Dao Audit Bureau, descends upon a cultivation world plagued by illegal cheat systems. Specializing in investigating and eliminating all kinds of unauthorized systems, he rescues Su Banxia, a low-level rogue cultivator, and hires her as a temporary assistant auditor. Together, they dismantle various cheat-system operations, including tycoon and daily-login systems, while confronting the forces of the Tianji Sect. From cleaning up chaos in the mortal realm to fighting their way into the Main God Space, they uncover zero-day vulnerabilities, battle the Main God itself, and thwart a conspiracy to plunder the fate and fortune of countless worlds, completing a high-risk cross-dimensional law enforcement mission.
