MC is retarded. Barely kills anyone and let's just about all his enemies live over and over again.
If you want to read a novel where you like to get annoyed that the MC is so dumb and the author portrays him like he's so smart and a genius then you might like this novel. Almost every chapter it's like "can the MC really be that dumb?"
"Can every character in this novel really be that stupid?"
Also a lot of things make absolutely no sense and at times contradictory.
"Does the author not think anything through properly and just pull random sh*t that makes no sense out of his ass?"
