[You see a helper robot with a material list in its hand leaving the workspace, not staying in the laboratory, and heading straight for the exit of the hall...]
"Finally!"
Mu You quickly manipulated his character to catch up.
[You followed the helper robot from a distance, leaving the Goblin Laboratory and heading towards the alchemy warehouse on the west side, apparently to extract materials.]
