三国鼎立时期,曹魏在巩固北方统治的同时,也没有停止统一天下的努力。在魏明帝时期和曹爽当政时期,曹魏曾两次伐蜀,但由于统一的条件并不成熟,这两次行动都未取得成功。三国后期,蜀国已经衰落,统一的时机到来了,已经掌握曹魏大权的司马氏发动了灭蜀行动,最终取得了成功。灭蜀行动拉开了统一天下的序幕。 During the tripartite confrontation of the Three Kingdoms, Cao Wei did not stop the efforts to unify the world while consolidating the rule of the north. During the Wei Ming Emperor period and Cao Shuang’s reign, Cao Wei had twice harmed his country. However, due to the unrivaled conditions of the unification, neither of these operations succeeded. In the late Three Kingdoms period, Shu State had declined and the time came for reunification. Sima Shi, who had mastered the power of Cao Wei, launched the operation to extinguish the Shu and eventually achieved success. Out Shu action opened the prelude to a unified world.
