Review Detail of SentinelSilence in Killer: I can shapeshift infinitely

I was wondering if I was reading the novel "Animal Assassin group" due to the blatant copy and paste of some of the sentences even paragraphs on this story. Rankings were not explained even the upgrades. I feel that this is an insult even considering it as a fanfic. At least use your own words and not just copy and paste someone's novel.
