Great novel that written by Rusty Dragon (or Decadent Dragon) with a little bit familiarity with 'The Devil's Cage', but with different touch that makes this novel have it's own kind of speciality. MC got transported into another world where he became 'postman' (or maybe delivery guy) but then got a chance or encounter with some trouble that grant him system ability (or predator talent, or in my taste I name it Gluttony King Talent). That talent grant him ability to be predator or to 'eat' 'someting' that will grant him points. That points have same taste like in 'The Devil's Cage', that can upgrade some abilities. There're some different here and there that make this novel has it own touch. MC is calm and cool headed. Driven to become stronger because of a sense of insecurities, trapped here and there, and many more. Well, there're bunch of girls. It's increase with next place he visit. First, there isn't any girl, then in the next place there is one, then in next place there're two, next is ... Many more. Even some of the girls are determine to find him o search him to another place (some have ability to do so). In short, this novel is great.
