BSM_Skkzarg, as I have stated in your other thread regarding this issue, the general's text does not change.

What changes is the honour bonus in that text and the promotion text (the one you get when your general is promoted). The promotion text is the one that states that your general's knowledge (the one that just got promoted to rank 8) matches Sun Tzu's.

The only way to see the changes must be by playing it. Of course, this was in STW. I don't have WE/MI yet so I don't know if that has been changed or not. I managed to do it by using Tokugawa Ieyasu who was rank 6 and used him to fight every battle and assault every castle. I sometimes retreated from a province after conquering it to cause a rebellion and fight there again so I could get up to 128 victories without suffering a defeat.
