Global Demon King: Starting as the Abyssal Dragon全球魔王：开局选择深渊巨龙

Not really. The problem with the "heroes" is that they underestimate the development speed of the MC. The MC is developing even faster than someone of his bloodline quality , seen from how fast the Succubus Queen is developing. So even if they account for him being a demon (which have a pretty fast development speed) and one with a pretty high bloodline, it is impossible for them to account for his hint cheat. Lastly the area where the MC is is not even that high level. Until the raws that are available we haven't even seen the shadow of the Church. A top organization that will spare no effort to destroy the demons. Besides any story or novel bigger than 120 chapters (2-3k words ones) is going to have some kind of repetitiveness. As long as the author is introducing enough new things (characters to locations to power realms to slight renditioned events) compared to things get repeated , I am okay with it. The only actual problem I see with this novel is that the MC is looking down on slow steady growth. He got addicted on fast improvement through heroic souls and he got arrogant for it. Something tells me that after T7 if he wants to remain relevant he needs to actually try. Until T 5-6 ( I don't quite remember what tier he reached) he has done almost nothing. He has been too reliant on his cheat. The early stages allow you to build up experience given the general low risk compared to later stages. Unless the author plans to end the story in the next 300 chapters , the MC is too inexperienced. He hasn't any plan made in case his cheat fails him.
