Chen Wei, a 28-year-old overworked office worker, is transported to the war-torn world of Qingyang and becomes a low-ranking border soldier. He unexpectedly binds himself to a mysterious system and awakens the ancient bloodline of the Qingyang Roar. Tempered under the guidance of veteran soldiers such as Wang Heng, he grows from a recruit who can barely hold a blade into a calm and decisive warrior. After surviving the bloody battle at Gubeikou, he slays powerful enemies with an ordinary human body and steadily rises through the ranks to become the Commander of the Youzhou Garrison. He also establishes an elite personal guard, the Qingyang Guards. Amid the iron hooves of barbarian armies and the turmoil of a chaotic age, he carves out his own path to becoming a military governor.
