Inazuma is filled with interesting and rich World Quests in Genshin Impact. Some of them are hidden behind certain mechanics or items that players need to find. One of such quests is the "Hiromu Surveillance" quest. To start this quest, you will need to find a very specific item.

In this guide, we will tell you how to start the "Hiromu Surveillance" quest and where to find Hiromu in Inazuma. Let's go!

How to Unlock and Start the "Hiromu Surveillance" Quest

To start this quest, you will need to find a special item in the Dragon Ridge. Head to the peninsula southeast of the Ridge (see the picture below).

There you will find three different bottles, and when you collect all of them, a new item will appear in your inventory called "Someone's Drifting Bottle", which is needed to start the World Quest "Hiromu Surveillance". You can see the exact location of all three bottles on the map below.
