Melchior Nimrod is teleported to a fantasy world and immediatly enslaved to a centauress. He's strapped with a collar that translates the local langauge and comes up with a bullshit story. To the centaurs he's the illiterate libraurian who the dark lord's daughter is teaching to read.
Melchior is biding his time under slavery. He's a gamer with a anti cultivator collar on. So long as he continues to level up his skills he should be able to get out of this situation in one piece.
