I Became the Worst Sister-in-Law in a Period Novel

The universally adored Lin Shuixian transmigrated into a book.

In every story set in a bygone era, there has to be a sister-in-law like this: crude and shrewish, fond of good food and lazy, spending every day bullying the heroine and making things difficult for her to stir up family conflicts, or taking advantage of her husband's absence while he serves in the army to squander his savings and flirt around.

In the end, she always gets face-slapping from the heroine, is despised by her family, and gets divorced by her husband, living out the rest of her life in misery.

Lin Shuixian transmigrated into the book as that very sister-in-law.

Theme: Build a fortune and work toward a moderately prosperous life, making each day better than the last.
