Seiken Tsukai no World Break + Dungeon ni deai o motomeru
Seiken Tsukai no World Break light novel already has 11 volumes out.
The bakatsuki translation group are translating volume 1.
The solitary translation website translated Dungeon ni deai o motomeru up to volume 4 but was taken down due to copyright and owner of site personal issues
Only those who have saved the translation have it now but I do not.
However I found a translation group who has taken up the project and is up to volume 5 part 1
