Well i wanted to start a new account so i cleared the cache of the game then uninstaled it like some post said but it was still logged to my account. Then i tried to just change player but it said ''This external account is already linked to the current game''. I really don't know what to do pls send help.

@alchu If it is the same as Dragon City you can only link one game to a facebook account. That can not be changed. You have to make a new account for a new game. Moving this from Dragon City to Monster Legends section.

@alchu each account needs 1 different fb or Google account for sync and saving the progress as mentioned. It's not possible to link 2 accounts with the same fb because it'll always go back to the account it was linked previously
