After I Transmigrated Into a Book, I Purified Nuclear Wastewater by Breaking Up Toxic Couples

Just after Si Yin had received a promotion and raise, the whole world entered the apocalypse after a certain country released nuclear wastewater. Si Yin died horribly in the claws of a mutated king crab, then transmigrated into a book as the heroine, the youngest junior sister of the Heavenly Dao Sect. She’d planned to take it easy, but when she learned that completing her mission could purify the nuclear wastewater, she sprang into action! Due to a System malfunction, the cultivation world spawned multiple scenarios. Bound to the Bad Romance Breakup System, Si Yin set off on a journey to break up doomed couples and return home to purify the nuclear wastewater. Her eldest senior sister was in a tragic romance scenario, where the male lead would torment her once, then twice, then three or four times? Break them up! Her second senior sister was in a chase-your-wife-to-the-crematorium scenario, where the male lead would cut out her heart, remove her kidneys, and dig out her spiritual roots? Break them up! Her third senior sister was in a scenario where a yandere fell in love with her, and the male lead would imprison her in the name of love until she died? Break them up! Her fourth senior sister was in a favored-by-all heroine scenario, where the heroine would kill her for stealing the male lead? Break them up! Her fifth senior sister was in a redemption scenario, where the male lead would coax her home with a single piece of candy? Break them up! Her beautiful master was in a powerful heroine ascension scenario, where she would cleave through the nine provinces with a single sword? Break them up... Just kidding! And her own story was that she’d meet the male lead, fall in love, and defect from the sect? I want to go home. Please hurry up and find someone else!
