How did the original god know which treasure chest he didn't take?

You can know which treasures you haven't taken in the following two ways:

View it on a small map. The minimap will show all the treasure chest locations in the current area. The selected treasure chest icon will turn gray, and the unselected treasure chest icon will light up. In this way, you only need to find the bright treasure chest icon to know which treasure chest has not been taken away.

Look through the treasure hunt compass. Different main cities need to make different treasure-hunting compasses. After upgrading the prestige level, you can unlock the maps of various treasure-hunting compasses at the corresponding prestige offices in major cities. Take Mond as an example. Turn left after entering the city and find Hertha. The reputation of Mond City has reached level 6, which can unlock the treasure-hunting compass of the wind. You can find a blacksmith to build it after unlocking it. Equipped with a treasure hunt compass, there will be streamers when you use it again. Follow the streamer position to find the treasure chest you didn't get.
