Daisy Rivers, an office worker, accidentally transmigrates into a cultivation novel and becomes the tool of Madeline Hayes, the original heroine—a treasure-hunting mouse. Just after arriving, Madeline Hayes brings people to hunt her down. At the critical moment, Moonflow Sect Leader Edward Rivers saves her and takes her as his youngest closed-door disciple. The sect looks like a villain’s den, but everyone is actually a great demon—Eldest Brother Jack Brooks is a direct descendant of the Phoenix Royal Fenley, Second Brother Stephen Wells is calm and strategic, Third Sister Aurora Brooks is a sword-cultivation genius, and all of them dote on her madly. Madeline Hayes seems gentle but is actually greedy; with the Upper Realm’s Dark Immortal Soul Warden, she keeps snatching opportunities and framing Moonflow Sect. Using her treasure-seeking gift, Daisy Rivers helps the sect survive crisis after crisis. In the fortune illusion, she awakens the residual spirits killed by Madeline Hayes to testify, exposing the truth of her “false destiny.” In the end, Daisy Rivers breaks into the core of Heaven’s Way, uses her auspicious bloodline to cut the false destiny line, and joins forces with her sect to defeat the Dark Immortal Soul Warden. Moonflow Sect reestablishes its mountain gate, and Daisy Rivers transforms from a cowardly little mouse into a junior sister who dares to risk her life for her sect.
