Concubine: the Spy in the Palace

She is the third one on the killer list, with a stunning appearance, but she was framed to death by her good sister... Once she traveled to this otherworldly continent, since God wanted her to be reborn, she would completely subvert all the rules and sink... She has never believed in love, but she fell in love with a man who will never love her. He always puts his own interests first, never talks about any feelings, and even sells everything for his own interests... After she was heartbroken by him, she resolutely let go, but he was tightly imprisoned by her side, waiting in the palace he gave her every day, enduring the infinite pain he gave her... Since both sides have to choose to use harm to make each other remember, then let her completely overturn the dynasty, let herself ascend to the highest position, and have a bird's eye view of the entire sky!
