Chapter 12: Sima Yi Usurps Power
第十二章：司马懿篡权
After Zhuge Liang's death, the internal situation in Wei changed. Cao Rui succeeded as Wei Emperor, but he was young and incompetent, unable to control the court administration. Great power gradually fell into Sima Yi's hands.
诸葛亮去世后，魏国的内部局势发生了变化。曹叡继位为魏帝，但他年幼无能，无法掌控朝政。大权逐渐落入了司马懿的手中。
Sima Yi was a person with great ambition. He had always coveted the throne of Wei, but the time was not ripe. After Zhuge Liang's death, external threats diminished, and Sima Yi began preparing to usurp the throne.
司马懿是一个极具野心的人。他一直觊觎魏国的皇位，只是时机未到。诸葛亮去世后，外部威胁减弱，司马懿开始着手准备篡位。
Sima Yi cultivated his own forces in the court and excluded dissidents. He appointed his trusted followers, eliminated political enemies, and gradually consolidated his position. Many loyal officials were framed by him, and court administration became increasingly dark.
司马懿在朝中培植自己的势力，排挤异己。他任用亲信，清除政敌，逐步巩固自己的地位。许多忠臣被他陷害，朝政变得日益黑暗。
Although Cao Rui realized Sima Yi's ambition, he was powerless to stop it. Sima Yi's forces were already deeply rooted, and anyone who wanted to oppose him would be suppressed.
曹叡虽然意识到了司马懿的野心，但他无力阻止。司马懿的势力已经根深蒂固，任何人想要对抗他都会被镇压。
Ultimately, Sima Yi launched a coup d'état, deposed Cao Rui, and established Cao Fang as emperor. In reality, Sima Yi had already become the actual ruler of Wei, and the emperor was merely his puppet.
最终，司马懿发动政变，废黜了曹叡，立了曹芳为帝。实际上，司马懿已经成为了魏国的实际统治者，皇帝只是他的傀儡。
Sima Yi's usurpation of power marked the entry of Wei into a period of decline. Although on the surface Wei still appeared powerful, internal corruption and power struggles had already deprived it of its former vitality.
司马懿的篡权标志着魏国进入了衰落期。虽然表面上魏国依然强大，但内部的腐败和权力斗争已经让它失去了往日的活力。
