Shen Zhaoning, the Duchess Protecting the Country with illustrious military achievements, returns to the capital by imperial decree, only to find that the estate has long since changed hands—the adopted daughter Shen Zhaorou has usurped the nest for years, while the true daughter Shen Qingqing has suffered hardship in the country estate. Believing that returning to the capital would just be another backyard farce, who would have thought this eldest sister, who carved her way out of the battlefield, would turn the abacus upside down with a cold face. The wild girl sent back is no longer someone to be trifled with; with the two sisters—one holding military power and the other entering the imperial court—everything once owed to them will be reclaimed in full with interest.
