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. In this exciting new area, you can complete quests and loot Chests that will disappear after the event period, so I highly recommend playing through this area when you have the time. One of the limited-time quests is called Daiya's Three-Day Reverie, which involves participating in a series of plays orchestrated by Hydro Eidolons.
How to unlock Daiya's Three-Day Reverie World Quest in Genshin Impact
To unlock Daiya's Three-Day Reverie, you must first complete Secret Summer Paradise: Part III - Dreams and First Encounters!, which will unlock the Thinkers' Theater in the Veluriyam Mirage. Once that's done, head to the Thinkers' Theater to automatically find a blue exclamation mark (it will only appear if you're nearby). Follow it to accept the quest from the loudspeaker.
How to complete Daiya's Three-Day Reverie World Quest in Genshin Impact
After speaking to the loudspeaker, Daiya's Three-Day Reverie will split into three subquests, all of which need to be completed in any order before you can proceed with the main quest:
After completing all three subquests, you'll be prompted to go to the Broadcasting Station. Start by following the quest navigator to the small clearing with a Hydro Eidolon. Its exact location is circled in the image above. Once you're there, look up to find Four-Leaf Sigils, which you need to use to propel yourself upward.

Once you're on the upper platform, follow the wooden path upward to find a house. Enter the house, which serves as the Broadcasting Station in the Veluriyam Mirage. Inside, approach the glowing spot to trigger dialogue with Paimon.
After the dialogue with Paimon, an entrance to the basement will appear. Go down the wooden stairs to trigger a cutscene and dialogue. Once that's done, jump down to the clearing with Hydro Eidolons to prompt dialogue and complete the World Quest. Don't forget to loot your Luxurious Chest reward.
