Well he said "2 emarlds for 7 uu matter" so I am right to presume 2 emarlds my turn into 7 uu matter.Ok seriously. Did you actually read what they wrote or are you trolling..? He is trying to get beryllium cells and he wants to use emerald dust but is saying 7 uum = 2 emeralds and ~29 emeralds for cells means a lot of uum... So others suggested using enderpearls instead.
