Can you do me a favor, adventurer?

I am investigating the changes of water quality in the area. Can you collect some midstream samples from the waters nearby?

Walk south along the road in front of you and you will quickly come to a small bridge; just collect some water under that waterfall using this Collection Bottle # 1.
