Borrowed World, Returned Soul

A morbid dynasty where imperial power has fallen and the empress is a figurehead. On the surface, it's prosperous, but in reality, aristocratic families monopolize the court and maintain private armies. In this world, female power is seen as ominous or a plaything, unless one possesses extreme cunning or martial prowess. In her past life, she was a special operations commander codenamed 'Shura', skilled in close combat, cold weapon assassination, and tactical planning. She transmigrates into the body of a mute slave girl of the same name, whose vocal cords were damaged by long-term abuse, rendering her unable to speak—but this becomes her best disguise.
