Xiang Li, a strategy lecturer at the National Defense University, woke up from a dream and became a closed disciple of Fan Zeng, a counselor under the Overlord of Western Chu. On the eve of the Hongmen Banquet, the wheels of history are rolling in. Xiang Li possesses modern military theory and game wisdom, and vows to change his fate against the will of heaven! He proposed the poisonous plan of "Ba Shu Mu" to divide the country, laid the psychological warfare trap of "Chen Cang False Information", used sand table deduction and Lanchester Equation to persuade the overlord, and tried to ensure that Han Xin would be the "halberd-bearing man" under his account. Refusing to forcibly reverse history, he promoted the "Chu River-Han Boundary" to become a strategic buffer zone, and even pioneered the "union of vertical and horizontal councils" among princes to leverage the system to shape war! Let's see how Xiang Li used his intelligence as a blade and the system as a shield to write an epic legend of a strategic deducer in the Shura field where Chu and Han were fighting for hegemony.
