Hi! Unfortunately I have forgotten about these two novels, so if anyone could pointthem out for me, I'd be really grateful to you. Thanks! 1) JP, isekai. MC goes to otherworld, tame lots of slimes and evolve them and etc. He opened a laundry shop with his slimes and earned big bucks. The novel was rewritten at one point. 2) KR. Some super famous wizard experimented with teleportation magic, got teleported to Korea, where mana is not present. Had to work as cleaner for years until everyone got teleported to tutorial area where mana is present, to prepare humanity for incoming monsters.
