NOTE: This guide only shows how to change your CID in already existing account.
It will affect the timer, but im not sure yet HOW.
I don't take any responsibility if you mess something up.
When i changed CID, the book turned grey, and so did my exp bar, but i get full exp from what i have observed.
1. Go to
http://passport.srocn.com/np/fcm.asp and log in
2. Click on the button on the left in middle of screen.
3. Enter new CID and name (in korean or chinese, not sure)
4. If you get i right you should see this:
As for valid CID, i won't post any here. I don't want to give it to everyone, cause some of you kids need a rest from this game.
If you want one contact me via anything and i'll give you valid CID.
Peace
