The Concubine's Daughter Came from the Apocalypse

Jiang An is an illegitimate daughter of a marquis's household who has suffered constant bullying. Her father doesn't care for her, her stepmother doesn't love her, and her concubine mother is weak. Her siblings treat her like a punching bag, and even stray dogs bark at her as they pass. One day, she was pushed into a lake. After coming down with a high fever, she soon died. When she woke again, the body had been taken over by a warrior of the same name, the strongest fighter of the post-apocalyptic world. Jiang An, after receiving the memories: ... In this feudal dynasty, where people are obsessed with the distinction between legitimate and illegitimate children, she knows neither how to read the room and flatter those above her nor how to handle the schemes and intrigues of the inner household. She doesn't have a peerlessly beautiful face either, so she can't attract fine young men from powerful families to brave fire and sword for her. But it doesn't matter. Her supernatural powers from the post-apocalyptic world came with her. Anyone who dares to impose rules on her had better ask the sword in her hand first. Tips: 1. An invincible, steamrolling heroine. Her combat strength is on a completely different level. Just enjoy the ride. 2. The heroine comes from the post-apocalyptic world and has almost no moral bottom line. Social conventions don't apply to her. Readers with high moral expectations of protagonists are advised not to read. 3. There will be other transmigrated supporting characters. Core theme: Only strength of one's own can change one's fate.
