the northwestern border be fortified, but Sun Hao refused. Later in 272, Sun Hao would carry out an action that would lead to a major rebellion — summoning Bu Chan, the general in charge of Xiling (in present-day Yichang, Hubei), back to the capital back to Jianye. Fearful that he was about to be punished somehow, Bu Chan rebelled and defected to the Jin dynasty. While Lu Kang was eventually able to defeat Bu Chan and recover Xiling for Wu, the distrust the Wu generals had for their emperor had been thoroughly exposed and Jin generals became emboldened in proposing plans of conquest to their emperor. In the same year, Sun Hao, still holding grudges against Wan Yu and Liu Ping for their plan to abandon him and return to Jianye on their own, tried to poison the two of them. Neither died, but when they found out that Sun Hao was behind the poisoning they knew they could not do anything about it; Wan Yu committed suicide while Liu Ping died in distress. Lu Kang died in 274. In his final petition, he requested Sun Hao to strengthen the defences on Wu's western border, but Sun Hao did not do so. Further, he divided Lu Kang's forces into six different commands, although each was led by one of Lu Kang's sons. In 275, the senior Wu minister He Shao () suffered a stroke and was paralysed. Sun Hao suspected that he was pretending and had him arrested and tortured by whipping and by subjecting him to saws and fires. He died under torture and his clan was exiled. For the next several years, people wishing to flatter Sun Hao often offered him miraculous items (real or manufactured) that purportedly suggest that he would eventually destroy the Jin dynasty and unite China. Sun Hao's superstitious nature became even more aroused and he spent all of his efforts on plans to conquer the Jin dynasty. Fall of Eastern Wu In 279, after Sima Yan accepted the advice of Wang Jun and Du Yu, the Jin dynasty finally launched a major attack aiming to conquer Eastern Wu. The attack was in six prongs: with the forces led by Sima Yan's uncle, Sima Zhou; Wang Hun (); Wang Rong; Hu Fen (); Du; and Wang Jun, with the largest forces under Wang Hun and Wang Jun's command. Each of the Jin forces advanced
