Ascendance Of A Bookworm , Part 4 Volume 4 by Miya Kazuki

A determined young bibliophile uses her modern knowledge to expand printing and medical practices in a conservative, class-bound society, juggling the challenges of running a fledgling publishing business, protecting and providing for her household, and forging uneasy alliances with clergy, artisans, and nobles; as she adapts inventive solutions to technical and social obstacles, her efforts spark both progress and conflict that reshape her relationships and the wider community.
