代码中的[NATION100]应该是表示第一个剧本中的第一个势力，Lord = 139 ;何进就是表示君主是何进，其它的意思我也不是很清楚了，但那个Friendship 可能是友好度吧，如果你要加入新势力，就在相对应的剧本编号后加入，比如在第三个剧本里加入新势力的话，可以这样：
[NATION318]
Lord = 831 ;卑弥呼
IsUsed = 1
BGM =
Friendship =
15,20,27,20,37,20,64,20,151,20,174,20,273,20,304,20,305,20,328,20,376,20,386,20,415,20,572,20,579,20,587,20,593,

上面的[NATION319]就是一个新势力，我自己加的呵呵
