Back on the Day of the Bride Swap, the Marquis's Fake Daughter Goes on a Rampage

[Swapped marriages + real and fake heiresses + legitimate daughter + revenge + general] In her previous life, the Crown Prince carried on an affair with her younger brother's wife and plotted to kill her. Mu Jiug'e spent three years laying her plans. She ruined the Yan family, ensured Xiao Changxuan would have no heirs, and schemed with Prince Chen Xiao Changyan, Yan Shuyi's former husband, to bear the one and only imperial son. In the end, she became a wicked consort, reviled by everyone, and died pierced by ten thousand arrows. She could not accept it. She had given everything she had, only to end up living like a mad dog. She returned to the day she and Yan Shuyi were both to be married. This time, she no longer tried to stop the Crown Prince and Yan Shuyi from plotting to swap brides. She went along with it and married Xiao Changyan instead. If she couldn't escape the Xiao clan, then she would tear the sky above them apart, throw their dynasty into chaos, and become a wicked consort once more. Xiao Changyan dreamed of that drunken Mid-Autumn night from his past life. He saw Mu Jiug'e, once a radiant and dazzling woman general, now like a stray dog trapped in a swamp. Covered in scars yet untamed, her eyes wary of everyone, as if she might be caught and forced to bite at any moment. In this life, he would grant her every wish. He would make sure no one under heaven ever dared betray her again!
