This quest (maybe) is the continuation of In Expert Company I and In Expert Company II in Fontaine. It's because it will feature the same group of NPC in said quest. In this one, we will help (as always) a hydrologist with her research in Liyue. By the end, we will encounter the trio from Fontaine's previous quest.
How to Start Temporary Acclimatization Quest in Genshin Impact
Teleport to Mt. Lingmeng north waypoint and head northwest to the pavilion. You will notice Woliu and her quest icon on the map. Talk to her and start the quest.
Your first task is to place 2 instruments in the marked locations. It's close and marked with bright light so you won't get lost. After you're done, talk to Woliu again.
Follow the quest navigation and you will meet the trio from Fontaine trapped on a bridge with Treasure Hoarders on each side of the bridge. Defeat the enemies and you will talk to the group.
After getting the Mora from Woliu, find Ms. Qiu and her gang in Qiaoying Village. Talk to them one last time and you will complete the quest.
