Song Yao transmigrates into a book as the vicious female supporting character. To complete her villain missions, she spends five years courting death and offending the entire sect before choosing to fake her death and flee, hoping only to live a peaceful life. Unexpectedly, she returns to her own body by chance and is accidentally captured and brought back to the Nine Saints Hall, where she assumes the alias Lin Mu and becomes a disciple again. Focused on saving money to repay her debts and leaving the sect as soon as possible, she inadvertently reveals her god-tier spiritual root and extraordinary swordsmanship talent. The junior brothers and senior sisters she bullied in her previous life both hate her and remain concerned about her, while the original novel's male lead regards her as a formidable rival. As she repeatedly teeters on the verge of having her true identity exposed, she begins a frustrating yet hilarious daily struggle to survive within the sect.
