The Qing Emperor and Chen Pingping echoed each other and said that Lin Gong's death was the work of Dongyi and Northern Qi, thus achieving their goal of sending troops to Northern Qi. Lin Gong's death also caused the Crown Prince's power to weaken and Fan Xian's power to increase. In addition, the Qing Emperor had also given Minister Lin a big gift on the surface to provide a high-sounding reason for his son's death to send troops to Northern Qi. Thus, Lin Gong's death played an inevitable role in the Qing Kingdom's invasion of Northern Qi.
