Genshin Impact has a variety of different side quests to tackle. One of them is called Big Business, which is located near the Wangshu Inn. In this side quest, you need to retrieve three invoices for Landa. Two of those invoices are easy to find, and it can be found using the waypoint markers on your map. However, the third one is a bit tricky because you’ll need Noctilucous Jades.
Near Stone Gate, you’ll find an NPC named Bao’er who managed to find the invoice before you did. In exchange for giving you the invoice, she requests three Noctilucous Jades. Unless you’ve been exploring every nook and cranny in Genshin Impact, it’s likely that you don’t have these.
If you’re wondering where to find Noctilucous Jade, here’s how to get it.
Noctilucous Jade Locations
To find Noctilucous Jades, head southeast towards Mingyun Village, which is past Sal Terrae. You’ll come across a large cave, as seen in the map above. It’s near an inlet on the eastern coast.
Be careful, though, as there are Level 25 enemies in this cave consisting of Geo Slimes inside. There are also some Hillichurls and Dendro Slimes right outside. They shouldn’t be too hard to take care of.
Giant Dendro Slimes can spawn smaller, regular ones, which have the ability to dig underground and ambush you from underneath. Having a ranged character like Lisa for a hit and run strategy is helpful if you’re having trouble.
Assuming you’ve cleared out the enemies, head deeper into the cave. You should eventually reach an area with blue rocks inside the cave. These are your Noctilucous Jades. Coincidentally, there are three of them for you to get here!
After breaking the rocks and picking up the jades, just head back to Stone Gate where Bao’er is and trade them in for the invoice. Once you have all three invoices, talk to Landa to complete the side quest, Big Business.
That’s all you need to know about how to find the three Noctilucous Jades for the Big Business side quest. Stay tuned for more Genshin Impact guides.
