Lu Yi was one of the best generals of Wu. He is most famous for commanding the Wu troops at Yiling. He was able to soundly defeat Liu Bei who was angry and hell bent on revenge after Wu took Jingzhou and killed his sworn brother Guan Yu.
Lu Yi sided with Sun Ba in a heir dispute. Sun Quan dismissed him from the court for this and he later died of grief. He was father to Lu Yan and Lu Kang. However, in the book, this is neglected and he is merely sated that he died... he died on the same chapter as Sima Yi and Sun Quan.
