According to the Records of the Three Kingdoms, he died at the age of 42. Died in the inner hall of Sun Quan. Lv Meng (178-2 19), with the word Zi Ming, is the third figure among Wu Dong's four British generals. Sun Quan defected after he succeeded to the throne, and showed his talents in the battle to wipe out mountain thieves outside Wu Jun. Lv Meng didn't go to school in his early years and was a lout. However, Monroe is not a person without a plan. When Zhou Yu attacked Nanjun, he also asked Monroe for tactics. Later, Sun Quan saw Monroe's ability and suggested that he read more military books. This is the famous "Sun Quan's persuasion". Lv Meng immediately asked for leave to go home and study the art of war seriously. Later, Lu Su came back and talked with him, lamenting, "In the past, Amon was under Wu, but now it is like this." Lu Meng said: "It is even more important to sit up and take notice in three days." In 2 17, Lu Su died of illness. Monroe soon became the third commander-in-chief of Dongwu Water Army. Then, Guan Yu attacked Fancheng, and Lv Meng successfully captured Jingzhou by crossing the river in white, which made Guan Yu defeat Maicheng. As the main commander, Lu Meng surrounded Maicheng again and finally captured Guan Yu alive. In 2 19, Lu Meng died of illness, and everything Sun Quan gave him before his death was returned to Sun Quan, which touched Sun Quan greatly.
