Unlike the shell which now protects you, the skin and scaley hide fight you as you peel them off, and you wind up putting a few holes in it that will probably make it last less time. Still, it's got a generous helping of meat involved, but you can only wish you'd run across a bag of holding or whatever so you could store it in there. Man, all the other isekai's give their character one, this one sucks. Smoking the meat does seem to preserve it, at least it's drier and tougher to eat, but you'll only know for sure given time. It doesn't make you vomit instantly either, another nice plus.

Well, last time I tried to do a puzzle, you got frustrated and completely forgot the highlighted solution, so I'll probably leave it as combat oriented unless you want a physical/skill challenge?
