Xiao Mianmian, the ancient auspicious beast Pixiu, was reincarnated as the newborn daughter of King Duan Wang Xiao Heng, the Great Demon King of Kyoto. When she was born, she used the power of the auspicious beast to save the father and daughter who were supposed to be executed. She even accidentally let Emperor Xiaowu hear her voice. With her quirky spirit and auspicious qualities, Emperor Xiaowu favored him, and Emperor Xiaowu gradually paid attention to Prince Duan because of her. At the birthday banquet, the prince and Pingyuan Hou set up a trap to kill the father and daughter, coaxing Xiao Heng to send Xiao Mianmian to the beast. Xiao Heng did so to save his wife, but as soon as Xiao Mianmian was put down, the majestic white tiger suddenly pounced on her.
