continued to show his sincerity and loyalty towards Sun Hao by being candid and not mincing his words whenever he gave advice to the emperor. Alleged plot to overthrow Sun Hao According to one account, sometime in January or early February 267, Lu Kai plotted with Ding Feng and Ding Gu () to overthrow Sun Hao while he was visiting the imperial ancestral temple, and replace him with Sun Xiu's son. Lu Kai then secretly instructed an official to recommend Ding Feng to lead the 3,000 imperial guards escorting Sun Hao to the temple. However, Sun Hao rejected the suggestion and chose Liu Ping () instead. Lu Kai and the others then contacted Liu Ping and asked him to join the plot. Although Liu Ping refused to participate, he also promised them that he would not reveal anything. Without Liu Ping's help, the plot could not be carried out. Around the same time, an imperial clerk Chen Miao () warned Sun Hao that there were ominous signs (e.g. dark clouds but no rain, winds changing direction) so Sun Hao, being superstitious, ordered his guards to be on high alert. The Wu Lu () recorded that Lu Kai had instructed his son Lu Yi () to secretly contact Liu Ping and ask him to join their plot. However, before Lu Yi could tell him, Liu Ping, who was not on good terms with Ding Feng, smiled and told Lu Yi: "I heard that a wild boar broke into Ding Feng's camp. That is a bad omen." Lu Yi thought that Liu Ping already knew, so he became fearful and did not dare to say anything about the plot. Death When Lu Kai became critically ill in 269, Sun Hao sent Dong Chao (), the Prefect of the Palace Writers, to visit Lu Kai and hear his last words. Lu Kai said: Lu Kai died sometime between 11 December 269 and 8 January 270 at the age of 72 (by East Asian age reckoning). Family Lu Kai's son, Lu Yi (), also served in the state of Eastern Wu like his father. He started his career as a Gentleman of the Yellow Gate () before enlisting in the Wu army and rising through the ranks to become a Lieutenant-General (). After his father's death, Lu Yi was reassigned to serve in the imperial palace, where he became an attendant to the crown
