The Saint’s Magic Power is Omnipotent (Manga) Vol. 7

A SAINTLY SECRET RECIPE Summoned to another world at the end of a brutally long workday, Sei was shocked to find herself thrust into the role of savior. Yet there’s no denying the holy power of her magic, or that it has helped protect the realm from darkness. Now she’s been sent off to the Klausner Domain, a region known for its peerless accomplishments in alchemy and potion-making. There, a certain book falls into Sei’s hands, one which contains the formulas for secret potions known nowhere else. Yet it’s not what’s written in the book that shocks her most, but the identity of its creator…!
Series Overview: Living the workaholic life in her mid-20s, Sei never expected she’d be summoned to another world, let alone obtain the power of a living Saint. And she especially didn’t expect to be totally ignored by the locals! While the kingdom desperately needs a hero, it turns out Sei was just the backup option. Left alone, she explores her newfound powers at the royal Research Institute, unraveling the mysteries of magic potions. As she helps the sick and the dying, her talents reveal themselves. Might Sei be the Saint this world needs after all?
