Shen Weixi, a top assassin trained by an enemy country, disguised herself as a weak princess and a close relative of Beirong. Her mission was to assassinate the "Mad King" Murong Lie, but after witnessing the decay of her motherland, she developed greater ambitions - instead of becoming an abandoned son after completing the mission, she would rather directly become the queen of Beirong and control both countries. Murong Lie had already seen through that she had a purpose for breaking up with her husband. He regarded her as the most interesting prey and planned to play a game of usurping the throne and conquering with her.
