Even if the author and the writing is still amateurish because he/she implied that he/she is still a student.
But I really enjoyed it, he post chapters every 2 or 3 days, and the novel is mostly dialogue, the fight scenes are sometimes good, but I still enjoy reading it.
As far as I know, there's like 7 or 8 real life Mythologies in the novel, and he uses the stories of the Mythologies as part of the plot. (He even uses real life religion too like Judaism and Christianity are the one he always use.) And he makes sure that the things he write would be accurate to the stories in both the Mythologies and the Religions, but there are times that he would change some parts of it and makes his own version, but not a lot are changed.
