The story takes the end of the Five Dynasties and Ten Kingdoms, during the reign of Chai Rong and Xiande of Emperor Shizong of the Later Zhou Dynasty (it is assumed to be six years after Xiande, assuming that Chai Rong did not die of illness) as the starting point. It tells the story of Li Yan, a prisoner possessed by a modern soul, who takes advantage of the "collapse of Youzhou city wall". "Tian Zhao" changed his destiny against the will of heaven, gradually took power, assisted (or even influenced) the hero Chai Rong, not only regained the sixteen states of Yanyun, but also wiped out the countries, reformed the system, and finally realized the majestic epic of unifying the world and reshaping China.
