The Summertime Odyssey event has provided new daily content for Genshin Impact's seasonal celebration since it began, and now, another part of the Golden Apple Archipelago questline is available to complete. After you've finished the quests found inside each island's mirage, it'll be time for a sort of treasure hunt. There's a manuscript with directions to follow, but they can be a bit confusing. So, for those who need a bit of help, here's how to get the missing Crystalline Cores.

Persikov's Manuscript Puzzles

There are three Crystalline Cores in total, and three separate puzzles on three different islands need to be solved in order to obtain them. We'll go through each island one by one from the closest to the farthest.

Northern Island Crystalline Core

As you may have noticed in Persikov's manuscript, there are devices set up on each island that can be turned either to left or to the right. On this island, there are two such adjustable devices. Using the image below for reference, start with the device on the left side of the stone pillar.
