Review Detail of maniac_008 in Born in Blood

I am liking this novel a lot. There are small things that are not written well or are unsatisfactory according to me, but its passable. The only issue or problem with this novel is the ranking system. There are three different rankings for the three forms of power. Then there is a fourth ranking which is based on the accumulation of the three previous rankings. The problem is that this fourth ranking is not specifically mentioned about how it is formed or what combination of the 3 rankings make each of the fourth combined one. Then there is the issue of the item rankings. Higher rank beasts are used to make lower rank weapons which somehow have their own rankings. i would like to suggest making a clear chapter in the start, before the novel begins, properly indicating all the rankings and a bit about what constitutes them. A separate chapter only for the separate three rankings and what combination of them leads to the fourth combined rank.
