Lin Yiran accidentally binds to a supplies system and transmigrates into a book, becoming the fourth madam of the Defenders' State Duke Manor. Foreseeing that the Xiao family will be framed and the entire family exiled, she collects food, medical herbs, gold, silver, and equipment in advance with ample reserves. The journey of exile is perilous; she takes out supplies to care for the family, cleverly sets up mechanisms to avoid pursuers and beasts, plans together with her husband Xiao Yunzhan, treats refugees and villagers kindly along the way, supports and understands each other as a family, sticks to her original intentions in adversity, steps out of hardship bit by bit, and welcomes a stable new beginning.
