Yun Shu is a transmigrator and a struggling writer who gains the ability to see readers' true thoughts. Using this power, he perfects the kill methods for ghosts in the Ghost Gate game. He has cleared five trials alone at record speed, each completed in about a day. He is ruthless and efficient against ghosts but can be humorous and social with people. Though initially reluctant to join any guild, he eventually cooperates with the authorities and Qingshui Guild to deal with the emerging Ghost King. His full identity remains mysterious to other players.
