To add, Zhuge Liang's Eight Diagrams Array immediately became a double instrument array after Sima Yi sent people into the array. Finally, all the gates were closed and all the soldiers who rushed to the array were killed. Only three generals were left alive, and Zhuge Liang sent people back to Sima Yi's array to humiliate him. Finally, Sima Yi left the army, the whole army was defeated, and then fled. Zhuge Liang didn't kill them because of the food ration.
