Modern office worker Lin Qingyin transmigrates into a deposed concubine banished to the Cold Palace—and accidentally binds with a Lucky Koi System! Anyone who harms her gets cursed with misfortune; anyone who helps her gets blessed with luck! A eunuch who skimps on her rations instantly breaks his leg; the Imperial Punishment Bureau's palace search backfires repeatedly; even the Empress's poison attempt makes her collapse on the spot. With her heaven-defying lucky koi aura, Lin Qingyin tears down the Empress, humiliates Noble Consort De—and rises from discarded concubine to ultimate victor!
