Completed(No space system, no system, no CP. Everyone says that if you transmigrate into these chaotic times, you won't survive three episodes. Read this book and you'll survive ten!)
Jiang Zhi transmigrated into a book, becoming the villainous aunt-in-law who abused the protagonist in a male-oriented novel. She is about to be killed. Instead of trying to curry favor with the male lead, Jiang Zhi abandons him completely. Relying on her extensive knowledge of herbs, she survives the chaos of war and turmoil.
She reclaims wasteland, farms, and raises a wild boar as a pet. Gathering herbs and manufacturing medicine leads to wealth naturally. Living in seclusion in the city, this is a different kind of pastoral life and a different kind of farming novel!
