Review Detail of ridereading in Dungeons Online

The start is totally confusing. I know that he m did not reincarnate or something but why is that that his knowledge is MORE THAN the rank player claudia. Rank player are experienced player but why is it that he is more than experience than the rank player? also in the summary it is only said that the game only release a bit of information but from the protagonist decision from the start is like know it all and it is like he comes back from the past. I don't know if I understand it right but this is my opinion I will reread again 😅.
