In 254, Sima Shi made a violent move to consolidate his power, at Cao Fang's expense. Cao Fang had aligned himself with the minister Li Feng (李豐), and Sima Shi had growing suspicions that they were plotting against him. He summoned and interrogated Li Feng, and when Li refused to disclose his conversations with the emperor, Sima Shi beat him to death with a sword handle and then accused Li Feng and his friends Xiahou Xuan (夏侯玄) and Zhang Ji (張緝) of treason, and had them and their families summarily executed. Cao Fang was further forced to depose his wife Empress Zhang, who was Zhang Ji's daughter. These moves further terrorised the officials into submission.
