After Sun Jun killed Zhuge Ke, he quickly moved to consolidate his power. He initially, on the surface, shared power with Teng Yin, but he, with control of the military, soon became even more dictatorial than Zhuge Ke. In particular, he falsely accused the former crown prince Sun He of conspiring with Zhuge Ke, and forced Sun He to commit suicide. His autocratic actions led to a conspiracy between Sun Ying (), the Marquis of Wu, and the army officer Huan Lü (), but he discovered the plan in 254, and both Sun Ying and Huan Lü were executed.
