首先需要第一个MOD，那就是可以自由切换地产的MOD
第二个MOD是X-EDIT,这个MOD里面有一个全面建设领地决议，可以直接建造建筑
第三个MOD就是Easy De Jure Drift，简易整合法理
第四个MOD是自建公国
首先进入游戏后，先使用自建公国，这样就会创造一个公国建筑槽
第二步控制台输入event major_decisions.3001，建造暖房可以开启一个特殊建筑槽
第三步迁移伯爵领首府然后，使用建造暖房决议代码，开启一个特殊槽，然后使用简易整合法理MOD，这样新的男爵领也会获得一个公国建筑槽，重复以上步骤就可以把所有男爵领打上公国建筑槽和特殊建筑槽
第四步找到X-EDIT这个MOD的文件夹，COMMON/Modifiers/打开文件拉到最下面building_slot_add = 4，这个数字是加普通建筑槽数量的，不需要就改成0
第五步找到X-EDIT这个MOD的文件夹，COMMON/decisions,打开X_decisions.txt找到（title_province = {）这行代码，下面有add_building = castle_01。之类的代码就是要添加某某建筑，在这个后缀add_building = 添加你想要的特殊建筑代码就行了

add_building = legendary_statue# 传奇雕像
add_building = legendary_watchtower#传奇瞭望台
add_building = legendary_hunting_lodge# 传奇狩猎场
改完代码后点击全面建设领地就可以了，然后因为代码里面还包括了城市和神殿，我一般是把城市和神殿地产下面的添加建筑代码删掉，就在堡垒哪里保持需要修改的建筑代码，然后修改玩一个男爵领后把地产切换成城市，然后在修改一次需要的特殊建筑代码，然后在用决议建设一次，因为决议会直接覆盖之前的特殊建筑，只能一个个修改
修改完后就可以保存退出游戏然后关闭MOD，开局，这样就能开局获得一个自定义完美首都
