Qin Feng, a former armed police special forces soldier, unexpectedly transmigrates into the chaos of the late Sui Dynasty and takes over the body of Dou Tieniu, a condemned prisoner in Zhangnan County. The body's original owner is none other than the future Xia King, Dou Jiande, who will shake Hebei and rule as a power in his own right. From the start, Qin Feng is trapped on the execution ground, a fearsome executioner's blade at his neck, after being framed for murder by a local magnate and made a scapegoat. At the last moment, a conscription order for the second campaign against Goguryeo saves his life, only to throw him into the even more brutal vanguard camp, where half of every ten soldiers die, turning them into cannon fodder for a chaotic age.
Armed with the special forces skills and historical knowledge from his past life, Dou Tieniu, now Qin Feng, keeps a low profile and moves carefully through the law-of-the-jungle military camp. As he adapts to his new body and regains his strength, he secretly lays his plans, vowing revenge on Qian San, the man who framed him. He wins over fierce comrades and befriends a mysterious powerhouse. With his exceptional cunning and ruthless methods, he survives by the skin of his teeth on the Liaodong battlefield and begins to stand out from the cannon fodder.
Adrift in a chaotic age, only the strong can find a place to stand. Taking advantage of the late Sui upheavals, he recruits soldiers and horses, gives refuge to displaced people, and puts down rebellions. Step by step, he escapes his fate as cannon fodder, carves out a domain across Hebei, and vies for supremacy with warlords from every corner. At last, he sheds his humble origins and ascends as the Xia King
