Modern army staff officer Zhao Chen accidentally traveled to the late Eastern Han Dynasty during a border exercise, and his soul returned to the body of a dying military lord who served under Liu Biao, the shepherd in Jingzhou. Faced with the troubled times when the princes were divided and people's livelihood was in decline, he relied on modern military theory and strategic vision, starting from rectifying the defense of Xinye, and fought against all opinions to reform the military system, build water conservancy projects, and appease the refugees. Under Liu Biao, he deftly defused the factional strife between Cai and Kuai, defeated the vanguard of Cao's army at Bowangpo with the tactic of "camp step by step", and used the strategy of "joining vertical and horizontal lines" to unite Xiliang Ma Teng and stabilize Jiangdong Sun Quan. From the hinterland of Jingxiang to the dangerous passes of Bashu, from the Jianghuai battlefield to the Heluo plain, Zhao Chen used his golden-fingered modern wisdom to gradually build Liu Biao's camp into a strong army capable of conquering the world. He eventually assisted Liu in reviving the Han Dynasty, and wrote a "New Chapter of the Han Dynasty" where iron blood and power are intertwined at the crossroads of history.
