With Cao Shuang eliminated, the Sima family become more powerful in Wei and completely monopolised state power. Chen Tai initially favoured the changes in the political environment as he believed that Sima Yi was far more capable as a regent than Cao Shuang. However, he felt uneasy about the growing influence of the Sima family and became torn between his loyalties to the Wei emperor Cao Fang and the regent Sima Yi. To avoid getting caught up in the political rivalries, he requested to be transferred to the western border to guard against invasions by Wei's rival state, Shu Han. The Wei government commissioned him as a general and appointed him as the Inspector of Yong Province.
