找到文件：
盘符(比如楼主安装在D盘，就是D):\steam\steamapps\common\City of God I - Prison Empire\systemConfig\record1\FileServerUserInfo
用记事本模式打开FileServerUserInfo：就可以看到存档一的相关信息。
例如：
{"user_monthRevenue":165457,"user_dayOverhead":84777,"user_prestige":121,"user_money":81094,"user_monthMoney":212712,"room_level":1,"user_lastmonthOutlay":0,"user_deleteMoney":0,"user_monthIndex":0,"user_dayRevenue":47255,"user_influence":399,"user_monthState":0,"user_lasttaxMoney":0,"user_monthOutlay":331618,"user_notpaidMoney":0,"user_taxMoney":0,"user_lastmonthMoney":0}
其中"user_money":81094,"表示拥有的钱数，直接修改后面的数字再保存就好了。未测试超过游戏内显示最高数额。
