A graduate student in the Department of Modern History traveled through time and possessed Han Xin, a down-and-out soldier in the late Qin Dynasty. He activated the golden finger of the "Proficiency Panel" and rose from the humiliation of "crotch humiliation" by improving his proficiency in military strategy and tactics. He used his familiarity with the history of Chu and Han to avoid the original ending of "the rabbit dies and the dog cooks". He first surrendered to Xiang Liang and then attached himself to Liu Bang, but secretly accumulated power; The campaign integrated the princes, and designed to divide the alliance between Liu Bang and Xiang Yu. Finally, after the Battle of Gaixia, he refused to allow Liu Bang to cut down the feudal vassal, and united with Yingbu and Peng Yue to form a three-part world structure of "Han, Chu, and Qi", rewriting the tragedy of Han Xin's "birds are gone, bows are hidden".
