Pick a Famous General to Conquer the World

I would like to ask a few questions. The levels of military commanders are too simple. Readers have many opinions on epics and legends. Just these two levels cannot satisfy people. Except for those few in Water Margin, they are really not good enough. . . How could Lu Zhishen be better than Qi Jiguang? . . I feel that the author should be more rigorous about the level issue and try to base it on what the public thinks.
