I like this kind of story, hope (I don't think it will be the case...) he can continue to chill all story long (but I'm sure in 2 chapters max he already found 2 Waifu, became an Gold or Platinum adventurer, found at last one of his old homonculus servants (the Dark elf maid, I think she spoke more than the other and was blushing a few times... Waifu from the past?).
Edit: (Aaannd I just looked at the cover with the Dark Elf Maid...)
