"You've abandoned your training!" Yang screamed at him, "you're supposed to come here every day until we disappear."
"You don't know what the world is like out there for the last demon. You know they've already started targeting me? I need to get stronger, sorry if this isn't a priority of mine."
Levi doubted there was anything left they could teach him. He more or less had the basics nailed in alchemy, blacksmithing was another topic entirely though.
"Okay we understand that learning about our old ways shouldn't be a priority at a time like this. How about we teach you how to use your discipline then?"
"That would be great."
He'd been going in blind for months, he had no idea how to use his discipline properly. Lilith gave him an unusual vague explanation that even he couldn't crack. Something about using brainwaves, manipulating them into doing exactly what you wanted.
