Companion Stone?
That thing takes up too much space. To make room for more items in the Space Button, Ji You stored all the Companion Stones in her dormitory before heading to the Space Rift.
Alloy?
Mithril, Snow Juice, or...
Ji You is confident she can craft a low-level soul artifact from these, but has no confidence in making a Mid-level Soul Device. Mainly because these materials are too fragile, and the area for engraving the Array Diagram is too small. She has to construct the Array Diagram very robustly to use it on materials like Mithril.
So, what's left?
Ji You frowned, the more she thought about it, the more she felt that at critical moments, she was someone who messed up. Otherwise, why couldn't she steadily produce Mid-level Soul Devices?
A bit frustrated, Ji You decided to give it a try - selecting something randomly from the Space Button to test her luck.
"If you don't try, how would you know it won't work?"
Cough, cough...
