Chen Zian, the moderator of the Modern Military Forum, traveled through time and became Chen Xiaoan, a cannon fodder at the bottom of the frontier army of the Qin Dynasty. Not only was he bullied wantonly by Commander Zhou Dabiao and his life was on the line, he was also burdened with the blood feud of the original owner's father, son and brother who were unjustly killed. No one had ever imagined that this frail body contained a strong heart that could stir up troubles on the border.
With his modern military accumulation and the essence of "Sun Tzu's Art of War", Chen Zian saw through the plot of the Xiongnu scouts when they were crossing the border. He amazed the audience with his accurate judgment and was appreciated by the army commander. He volunteered to go deep into dangerous areas to serve as a scout, saw through the Xiongnu's conspiracy to cut off food routes in a desperate situation, and brought back key information on his own, and showed his early talents in the First World War.
Since then, Chen Zian has embarked on a thrilling counterattack: the weak defeated the strong in the martial arts competition, causing Zhou Dabiao to lose all face; in the military camp, he repeatedly used ingenious strategies and troops to defeat the enemy, and was quickly promoted from an unknown soldier to a corps commander and a hundred generals. He retaliates maliciously, digs out the truth, and uncovers the collaborators. Surrounded by the undercurrent of the military camp and the eyeing Huns, he works step by step with wisdom and courage. He not only clears the grievances of the original owner, but also creates a legend from cannon fodder to a good border general.
