Wuzhang Plains
When Zhuge Liang fell critically ill during the Battle of Wuzhang Plains, he attempted to extend his lifespan by 12 years through a ritual. However, he failed when the ritual was disrupted by Wei Yan, who rushed in to warn him about the enemy's advance. Before his death, Zhuge Liang also passed his "24 Volumes on Military Strategy" () to Jiang Wei, who would continue his legacy and lead another eleven campaigns against the state of Cao Wei.()
