When completing the hidden mission "Rusthelm Tavern" in "Genshin Impact", you need to answer a question. Many people don't know the answer yet, but after passing the level, you can get a strange treasure chest. If you don’t understand the answer, take a look!
1. We came to the Rusty Helm and talked with Permanya
3. Talk to Permanya again, start answering questions, select [three], [three], [sea dew flower]
3. Then operate the naval gun next to it to blast open the stone wall (just fire it directly) and open the treasure chest and teleportation point.
4. Go down into the cave and defeat the slime in the middle of the cave. Open the treasure box to find the first fairy and guide him back.
5. Then approach the jellyfish next to it, fly to the cliff to the north, and guide the second fairy
6. Finally come to the cliff in the south and use the water element to activate the obelisk
6. When the bubble is level with the reed pipe (and the platform on the right is descending), use a bow and arrow to attack the bubble on the left (normally the right one will be detonated by ripples, if not, just add an arrow)
7. After guiding all the fairies in the three places back, you can open the gorgeous treasure chest.
8. After opening the treasure chest, absorb the power of the heavy-armored crab and crush the boulders.
9. If you leave the cave along the ocean current, you can also get a rare treasure chest.
