Sun Chen
Sun Jun's death would precipitate a major confrontation. The general Lü Ju, who was set to lead the main force against Cao Wei, was angry that the autocratic Sun Jun appointed Sun Chen, who had not distinguished himself in any way. Lü Ju openly called for Teng Yin to become regent instead, and Teng Yin agreed to act with him. Sun Chen struck back militarily, and his forces defeated Teng Yin and Lü Ju. Teng Yin and his family were executed, while Lü Ju committed suicide. In light of his defeat of Teng Yin and Lü Ju, Sun Chen began to become extremely arrogant.
