Burdened with a monstrous injustice against the Prince of Mobei's household, Xiao Chen awakens his System, along with memories of his previous life as a special forces soldier, and raises the banner of purging the court of evil ministers. His generals follow him through life and death as they break through the court's schemes, foil the crown prince and treacherous ministers' plot to seize power, and clear his family of a decades-old stain.
Once the court's internal strife has settled, Xiao Chen takes up the Dragon-Subduing Whip and the Son of Heaven's Sword, then leads Mobei's iron cavalry across the land. He crushes the assassin organization known as the Dark Pavilion, launches a campaign against the neighboring mountain kingdom of Zhaoyang, and develops the grasslands and builds industries, all while his trusted companions remain at his side. He secures the borders, opens trade routes, and devotes himself heart and soul to restoring the foundations of Great Xia. When peace finally comes to the four corners of the realm, he swears brotherhood with the new emperor and is enfeoffed as the Prince Who Stands Shoulder to Shoulder with the Emperor. Kingdoms from every direction stream to court to pay homage.
