Use the Holy Seal by taking it to this location.
What to do with Holy Seals | How to use Sacred Seals | Genshin Impact
Version 3.1 of Genshin Impact is the latest version that has been released. Cyno and Candace banners for the first half and Nilou for the second half are included in this update.
In addition, it opens up the Sumerian Desert. We will show how to use a holy seal, one of the new features of the version.
You can visit the Sumerian Desert; however, you must first unlock the region to do this. You must complete the Archon Quest "Requiem of the Echoing Deep" and reach Adventure Rank 35 to travel to Sumeru.
