What should I do after collecting the overlord's card in the era of great navigation 4

If you get all the evidence of dominating the sea, don't rush back to the city where you started, then the game will be over, but it will definitely leave many regrets. At this time, your Excellency, you can explore and open all those unknown areas, that is, explore all the maps. You'd better find all the treasures, so that your character can be a perfect ending.

Friendly reminder: I don't know if you have noticed it. When you start playing for the first time, you will be prompted when you save the game. This is something like justice. This is important. Don't read the game halfway, then what you get is justice, so there will be many good things after the game passes. Once defeated, or after death, reading the disc will lose these injustices.

have fun!
