How to Obtain Treasure Chests

As I was playing, I noticed treasure chests but had no idea how to get them. After trying various things, I figured out how to get them and wanted to share. Once you get one, you'll get the hang of it and it should be easy to get them afterwards. While there's nothing super amazing in the treasure chests, they contain items that boost weapon or HP by 1%, which might not seem like much at first but will be crucial later on. As you can see in the screenshots, the order is the starting point, 1st opened map, 2nd opened map, and 3rd opened map. If you go in the direction your character is facing, you'll find the path. I started around 5 AM, and since the daily reset is at 9 AM, I've played for less than 12 hours in real-time, but it feels like I'm about 1.5 days in. I've opened 3 more maps besides the starting one. I haven't done the '4-island rush' that others have mentioned yet. I've only excluded the third opened boss and the incredibly strong character that drops purple items next to it ㅠ For now, they're on a respawn timer that I can't beat until tomorrow.
