Act II of Genshin Impact's 1.6 Midsummer Island Adventure is now available to play, offering new quests and islands to explore in Summer Vacation: Proceed with Caution. After you accept this quest, you'll be prompted to rest until the next morning (08:00 - 10:00). You'll need to skip a full day to complete the objective, since the game apparently wants your party to get some much-needed sleep. Then, you'll speak with Klee, Jean, and Barbara to trigger the investigation of the mysterious buoys.
This is where things can get confusing. You'll be told to "investigate the mysterious devices," but when you sail up to these strange buoys... nothing happens.
You need to destroy these mysterious devices using your Waverider's cannonballs (either Swiftstrike or Heavy attacks will work just fine).
