There are a lot of places to go in the AoZ app. Here is a list of what to do and where to go.
How do I get more than one account?
Yes, you can have more than one account in AoZ. You can switch between your acounts in My Info > Account . Make sure you bind your first account so that your information isn't lost when you Switch Accounts.
Account binding saves your city and commander information - services like Facebook, Google, Apple ID etc depending on your device.
Many players have a Farm account and a battle/active account.
