How long does it take to reset the heart of the astrolabe?

A month. Because if you don't accept the astrolabe for a long time, the astrolabe will disappear, and it is impossible for the other party to send you a heart fire every day. If it is not received for more than one month, it will automatically disappear and reset. In the light encounter mobile game, the position of the astrolabe is on the login slate of the encounter. When the player stands on the slate, two buttons will appear. Click the first button to open the ancestor chart of each map and summon the unlocked ancestors.
