and here are my thoughts at the 77% juncture by word count
it is much much shorter than combat continent 1 and 2
females characters too flat, some of them have a very small role to play in the big picture
they don't have too much to say about sharing the main character, more can be done to add some spice into the story IMO
main character starts out too flat. "Revenge, kill all though who oppose me", to "I am a maiden in love...". The author fixed this later by writing it off as a side effect of the heavenly demonic arts he practices after he starts practicing the fists of the furious god. He gains more depth as the story goes.
the battles always going in the same sequence. He find tough foe, they fight, he pukes blood. He wins, he recovers from life threatening injuries by going through inhumane torture which magically gives him a power up. He finds small fry, he vaporizes them, showing off how much stronger he has become.
the good points are how it is very true to its genre of being shonen. It is hot blooded. It has its emotional points. It shows how blood is thicker than water. It shows his redemption. It was an extraordinary adventure and a pleasure to read
