Bai Feifei is a girl from the outer city at the bottom of Shuguang City, with mediocre qualifications and nothing. Until one day, Xu Mo, the evil god from the past who claimed to be "senior", forcibly resided in her consciousness - and she became the vessel for him to come to the world. In exchange, Xu Mo helped her kill the aberrations, slap the rich in the face, and change her fate against the will of heaven. Bai Feifei fought her way from a criminal to the focus of the inner city, and even fabricated a shocking lie about the "Masked God Hidden Society" to suppress everyone. But Xu Mo never hides it - all gifts have a price, and the countdown to Dawn City's destruction has begun. Bai Feifei wants to save the world, but when the heart of the old evil god is beating inside her body - who is the one being controlled?
