Wu Mian, a white-haired man with immortality, lived for more than two thousand years. He saw Emperors of Qin and Han Dynasty, and also saw demons running rampant. He has a lazy personality and can lie down but never sit down. Until he was pulled into a mysterious agency called the "Poll Bureau", responsible for handling various supernatural events. Wu Mian said that he was not interested in saving the world. He just wanted to figure out why he would live forever and then end this boring life.
