Modern youth Xiao Jing accidentally time-travels to become the Third Prince of Great Dayan. After being plotted against by the Prince of Qi, he is banished from the capital of Jingzhao and assigned to the barren and chaotic Qinzhou. In his moment of peril, he awakens the Emperor Summoning System, summoning historical famous ministers and fierce generals such as Huo Qubing and Meng Tian, clearing out corrupt officials, pacifying mountain bandits, and reorganizing military and government, causing Qinzhou to rapidly rise. Afterwards, Xiao Jing pacifies the southwestern tribes, establishes Fanzhou, and defeats the imperial court's grand army to seize Helzhou. Facing the invasion of the Alei Kingdom, he leads a million-strong army to counterattack, conquering cities and territories all the way, pressing straight towards the royal capital. The once-waste prince who was at the mercy of others has now grown into a powerful overlord feared by both the imperial court and various nations.
