Xiao Jin, a modern special forces commander, transmigrates into the body of a “good-for-nothing” heir to the Jing'an Marquis's household in the Great Yan Dynasty. His predecessor was poisoned by his stepmother, had his meridians damaged, and was mocked throughout the capital as a failure in both letters and arms. When he wakes, he is already trapped in a deadly predicament.
Armed with modern military theory and combat techniques, he breaks the poisoning plot, repairs his meridians, and shocks the capital by defeating stronger foes. When the border is under threat, he seizes the chance to enlist after the Crown Prince frames him. He crushes the Xiongnu with lightning-fast tactics and establishes his authority through improved training methods, rising from “Colonel Who Breaks the Barbarians” to “General Who Guards the North” and earning the title “God of War.”
But when he uncovers a treasonous conspiracy within the Ministry of War, he is stunned to discover that the Crown Prince is behind it. As he pursues the truth, the assassin leader switches sides, and the truth behind his father's “illness and death” comes to light. The once-useless heir has long since transformed. With the spear in his hand, he stirs up the court; with his strategic brilliance, he protects his homeland. From a young lord cornered by death, he rises to become the pillar of the realm, holding the fate of the nation in his hands!
