Lin Xiaotian, a low-level female anchor with an ugly appearance who was ridiculed by the entire Internet, accidentally traveled through time and became the reincarnation of the ancient female Yama. During the day, she was still the ugly girl who was laughed at, but once the spell was cast, she transformed into a peerless beauty, possessing the supreme ability to connect yin and yang and end life and death. After twelve o'clock at midnight, her live broadcast room became the only channel connecting the Yin and Yang worlds, and Black and White Wuchang became her errand boy, allowing her to tell fortunes in the Yang world, catch ghosts in the underworld, and kill decisively. However, her abilities attracted the attention of the mysterious organization "Yin Yang Bureau". Director Mo Li launched a hunt for her. At the same time, she discovered that she was inextricably linked to the reincarnation of ancient Yama, the modern wealthy businessman Su Mo. As Lin Xiaotian gradually gained a foothold in the Yin and Yang worlds, a bigger conspiracy surfaced: someone was trying to break the balance of Yin and Yang and merge the two worlds. Lin Xiaotian must deal with disputes in the Yang world during the day and deal with crises in the underworld at night. At the same time, he must face Su Mo's indifferent attitude and Mo Li's pressing step by step, and finally uncover the truth about his own journey and protect the balance between Yin and Yang.
