The Genshin Impact Secret Summer Paradise event runs from July 5, 2023, to August 16, 2023, allowing you to explore the Veluriyam Mirage for a limited time. I'm really excited about this new area as it's full of Chests and quests that can only be completed during the event period. One such quest is Daiya's Three-Day Reverie, which branches out into three subquests, including The Black Nacre and the All-Devouring Kraken.
How to complete The Black Nacre and the All-Devouring Kraken World Quest in Genshin Impact
Head to the area circled in the image above to trigger dialogue with a loudspeaker. Once that's done, board the Choo-Choo Cart, which will take you to a swampy area inside a cave.
Once the Choo-Choo Cart stops, you'll be given an objective to defeat the sea monsters. Interact with the cannon to Operate it. Start by angling the cannon upward once, then fire at the sea monsters that have emerged from the water. Once all three in front are done, angle the cannon upward one more time and fire at the sea monsters at the back.
After defeating all the sea monsters, exit the interface to prompt an Exquisite Chest to spawn. Then, board the Choo-Choo Cart again. It will take you deeper into the cave.
When the Choo-Choo Cart stops, follow the wooden path toward the dead end, where you'll find a Streaming Projector. Interact with it to begin a Preprint puzzle.

This Preprint puzzle is simpler than usual and functions more like a mini-game. All you have to do is avoid enemy attacks by making sure that you're outside of the areas marked by the red lines. Pay attention to your HP bar, marked by green hearts at the bottom of the screen. It will dwindle every time you get hit, and once all hearts are gone, the challenge will fail.
The mini-game gets progressively harder and will eventually introduce barrels. The enemy attacks can't penetrate the barrels, so you can hide behind them or jump on top of them to avoid getting hit. Once the mini-game is done, a door will spawn. Interact with it to exit the Preprint world, where you'll be rewarded with an Exquisite Chest.
Next, head toward the nearby cannon and loudspeaker to trigger dialogue. Interact with the cannon to Operate it.
The cannon will automatically face the blocked path up ahead, so you don't have to adjust its horizontal position. However, you need to angle it upward twice so that it looks like the image above. Once that's done, fire at the blocked path to reveal an exploration area further inside.
Follow the path that just unblocked to reveal a pile of gold. Approach it to trigger dialogue, completing the World Quest. There's a Precious Chest that's camouflaged really well—don't forget to loot it for a limited-time reward!
