Ancient City Key Location

Ancient City Key can be obtained from an Exquisite Chest behind a locked gate that is opened by lighting the two Jade Incense Cauldrons in front of it. Position yourself such that the two cauldrons are aligned between you and the Adeptal Energy to light both of them in one go.

It also comes with the Chizhang Map that gives a clue about a warehouse where the Ancient City Key is used.
