Review Detail of king_of_Demons in Epic Of The Demonic Sage

I have read 50 chapters untill the part where I have to unlock new chapters and I am not happy. I was entreaked by story read it with 'patience' (I have emphasized patience bcz I don't have a lot of it) I also have very short attention span like I get bored quickly but author did a great job at synopsis and his tags I read it and many times slept in reading the chapter in between I am bored out of my mind after reading it till now and honestly feels like I wasted my time like story progresses at a snails pace mc is like recovering for who knows how long and I cannot explain it in words but the tag overpowered will come into effect after 1000 chapters the way it's progressing.I have dropped it's just too slow ,even if author said it will be slow but there is nothing really going it is just slow for sake of being slow you know what I mean.
