Su Shixiao transmigrates into a cliched historical romance novel as a minor villainess whose sole purpose is to highlight the male lead's ruthlessness. However, she decides to take a different path. Instead of vying for the male leads' attention, she aims to overthrow their kingdoms and become the empress herself. With a system that encourages her to be the "white moonlight" in the hearts of the male characters, Su Shixiao chooses to focus on infrastructure and development, believing that wealth comes from building roads, planting trees, and reducing population growth.
