In order to earn tuition, Jiang Xiao, a doctoral student in the Department of History, participated in a live broadcast of unpopular quizzes. However, he was accidentally bound to the "Wanjie Live Broadcast System" and connected with emperors and generals of past dynasties in parallel time and space. The question involves the future, the punishment is social death experience, and the reward is advanced knowledge. From then on, Ying Zheng began to study gunpowder chemistry, Li Shimin made plans in advance to prevent the Anshi Rebellion, and Zhu Yuanzhang worried about his descendants... History went completely violent. And Jiang Xiao discovered that as the civilizations of various dynasties went crazy "cheating", rifts in time and space quietly appeared. She was forced to upgrade from a "historical anchor" to a "time and space gatekeeper" who maintains the balance of civilization in the center of the butterfly storm.
