Madam Leisi

(Transmigrate into a book + farming + an old woman + no romance + a small pocket dimension)

It turns out that saving someone's life really does bring good fortune. She transmigrates into a book and becomes an old woman with children, grandchildren, and four generations living under one roof.

The good news: her husband is gone, and her son is a marquis.

The bad news: just as she arrives, her son is stripped of his title.

The good news: they aren't exiled.

The bad news: the whole family is driven back to their hometown.

The good news: there is farmland back home, and they can bring some gold, silver, and valuables with them.

The bad news: in the book, her family meets a tragic end.

To change their fate of dying horribly, she leads her family of old, young, sick, and weak in the hard work of farming, improving the soil, and cultivating better food crops, hoping to stay alive through the next coup.

Unexpectedly, she becomes an expert farmer, earns an imperial title for her virtue, and leads her family back into the circle of the powerful and elite.

(This story is slow to warm up, slow to warm up, slow to warm up! It's not a wish-fulfillment novel. It has frustrating and potentially upsetting elements. The heroine isn't all-powerful, and she doesn't have an impressive golden finger. The pocket dimension plays a very, very small role.)
