Book Transmigration: The Cannon Fodder Grows Crops, Sells Medicine, and Supports the General in the Stars

After accidentally transmigrating into a book, the doomed side character must save herself and others. Yao Wenqian glances at the cold-faced man beside her, then at the plant leaf in her hand. For a better life, she can grow a medicinal garden, overcome a few genetic defects, do the public some good while making a little extra on the side, and even end up with a husband who fits her tastes. She's in. A softhearted, playful snarker versus a rational, sharp-tongued, jealous straight-laced man.
