Around this island, there is also a map.
"This map should be the map of this relic."
"That island should be the central island of the relic, and the floating Copper Mirror above the relic is likely the treasure within this relic. That colorful glow suggests it's at least an Earth Level Treasure!"
"Look at the map, there are light points scattered across it, with two particularly conspicuous ones. If the central one is the final island, then the other one is where we are."
"In between, there are several dim light points, which should be the islands we need to pass through. As long as we traverse these islands, we can reach the final island! In other words, whoever moves faster can reach that island first!"
"Therefore, we took the wrong path earlier, and our pace was a bit slow."
