Changle of the Han Dynasty: I Changed My Destiny for Han Xin.

At the end of the Chu-Han War, the "Fateful Echo" system was introduced. The protagonist travels back in time to Han Xin, and knows the established ending of "the rabbit dies and the dog cooks". The core goal is no longer to assist Liu Bang to unify the world, but to use the prediction of the historical trend to break the original dependence relationship between monarch and ministers and build a new three-legged structure of "Chu, Han and Qi".
