Isekai Tensei: Recruited to Another World (Manga): Volume 6 [EPUB ebook] 

The new “slow life” of reincarnated adventurer Tenma continues in the city of Sagan, where he’s tamed a new baby dragon follower, one which attracts a lot of attention. But that’s not his only dungeon discovery—he comes across two slave girls whose master was killed by a giant snake monster… And now they want Tenma to be their master?! Owning slaves definitely was not on Tenma’s priority list, but the girls might be separated otherwise… He can’t just let them be!

Follow Tenma in the next phase of his journey, exploring dungeons and making new friends!
