Review Detail of Enchants in Fantasy Assassin in a modern world

despite my 3.6 score, I really quite enjoy this novel. What I have a problem with is the illogical nature of the new world he's in. Martial artists / rich people act just as unbridled as they would in a medieval setting despite being in a modern setting, quite openly either threatening or killing/kidnapping people. A martial artist with the tiniest of strength is feared as if calling the police wouldn't work perfectly fine.
