Li Yu'an, a doctor of history, accidentally traveled to Longzhong in the twelfth year of Jian'an. Relying on the modern knowledge system, he took the improvement of craftsmanship as the starting point and became Zhuge Liang's most important collaborator and ideological collision. When the advantage of a "prophet" fades with historical changes, he must use modern thinking to re-deconstruct the troubled times and find a hard way between innovation and conservatism, efficiency and people's hearts.
Starting from a workshop, he helped Shu Han build a military and political system that transcended the times. However, every change touches interests, and every victory has a hidden price. When ideals touch the core of power, he and Zhuge Liang also face the ultimate choice of ideals.
Purpose: Change the trajectory of history
