In 249, while Cao Shuang and the emperor Cao Fang were away at the Gaoping Tombs, Sima Yi seized the opportunity to stage a "coup d'état" in Luoyang and take control of the imperial capital's armed forces. He promised Cao Shuang that he would spare him and his family if he surrendered. Cao Shuang believed and relinquished all his powers as regent, thus leaving Sima Yi solely in control of the Wei government and the puppet emperor Cao Fang. Later, Sima Yi broke his promise as he had Cao Shuang and his supporters arrested, charged with treason and executed along with their families. At the time, Li Sheng had yet to leave Luoyang for Jing Province, so he too was arrested and executed together with his family.
