How to Begin Messenger Side Quest
To start the Messenger side quest, you must find the Chuyi. He will be inside an underground cave. This cave can be seen near the teleporter at Wenye Beach, looking south at a settlement. The quest will automatically appear on the map when you are near the area.
Chuyi Location
From the teleporter, look directly south until you see the settlement. Once you see it, the entrance to the underground cave is beside that. Jump down and follow the quest marker to get to the Chuyi.
Talk to the Chuyi
Chuyi will ask you to deliver a data chip to a researcher.
Talk to the researcher
The researcher will just be standing outside the cave. Follow the quest marker and give the data chip to conclude the quest.
