Well, i'm dropping this...
I don't even know how this novel made 'top 30', but I don't think it deservers it. I agree that world building is good and power system is good. God, MC is a simp to the point of extreme. He acts arrogant after simple power up and gets beaten up by a random character. MC make rookie mistakes and flexes before young masters and decides not to kill until author drags story. It is worse than many braindead chinese novels. At least Chinese novel's MCs can man up and kill his enemies. But this novel's MC is too much of a simp to kill his enemies and he lets them play with for hundreds of chapters.
It's like author is doing everything he can to make MC into a simp and a pushover.
