Cheng Ye, a doctor of modern game theory, was transformed into the orphan of a counselor whose country was destroyed at the end of the Warring States Period. He has no systematic golden fingers, only modern game thinking engraved in his bones. In an era when everyone plays zero-sum games and pays attention to life and death, he plays Nash equilibrium and repeated games. Starting from a black coal mine owner in the suburbs of Xianyang, he used original KPIs to solve the problem of miners' slack work, and was favored by the incognito Li Si. He wanted to help Qin unify the world, but not by massacre and power, but by trying to build a "sustainable algorithm of rule" - making the conquered feel that "obedience is more cost-effective than resistance." When other country's counselors were still pretending to be sophisticated with rhetorical questions, Cheng Ye directly threw out data models; when others were trying to discord, he designed an "integrity points system" to allow enemy generals to proactively maintain a tacit understanding for long-term interests. He wanted to change the rules of the game in this era, but he triggered the rebellion of the old aristocrats and Legalist radicals. This is a collision between modern thinking and the bloody reality of the Warring States Period, a game that uses conspiracy to change history.
