Review Detail of Naginn in In Marvel with King’s Powers(Nanatsu no Taizai)

Lots of harsh reviews based in nothing. The story takes it's time until it reaches the main events of marvel, but otherwise it's a nice story. People complain about the character not being a reincarnated person. I mean, he does not have all his memories, but he has knowledge of marvel so he still can be considered as reincarnated. Also people say it's a cultivation novel. We the way he describes his increase to power can be seen as such, but is not really cultivation.
