Reached 60 today, and decided to open a box. I've still got material boxes etc. The only chests I open are level materials, still have soul talismans and such. I still got red hogyo chests. The box that I opened had about a 100ish quantity to it but I didn't pay attention to the screen to what was revealed. I've looked in my inventory, cult frags, mod souls and nothing. Does anyone have an idea what sorta box you'd have that many of saved from start of the server?

Edit: Maybe hygokou hollow spirit? Any idea where to find it?
