Turn on auto-battle mode and allow your character to go to the battlefield and slay as many enemies as possible. Disable your device's auto lock mode to allow it to continue farming experience and treasure automatically. You can also automate the most of a quest. When in an active quest, tap the quest ma,e to send your character walking to it automatically. When in battles, tap the "Auto Battle" button to let your character do everything automatically except for healing. Do not do this against top tier enemies. To heal, tap the potion icon while the auto battle is in progress. Your character will still perform both regular and special attacks automatically.
