I downloaded chapters 065-082 from https://www.mangahere.cc/manga/tensei_shitara_slime_datta_ken/ and converted them into one .cbz comic archive for ease of use. This begins slightly before the end of the current latest English manga volume, vol. 15 (https://nyaa.iss.one/view/1330574) and goes up to what is currently the latest english translated manga chapter, at least that I could find. For those, like me, who don't want to wait until the release of vol. 16 to read the latest Slime antics.
