Up to chapter 190 and I'm officially done with this novel. The short of it is that the translation is so trash it makes reading torture, the characters are uninteresting and no real personalities besides their one or two personality points, the world background is nonexistent, and the story feels like it's on rails and pretty basic. If you want to read my extended review continue below, otherwise, yeah not that good of a story and sucks to read.
Translation: Let us start with the biggest offense of this novel. The translation is horrendous. Constant grammatical and sentence errors, names constantly change, sentences get cut short or make no sense, and overall felt like MTL or done by someone with a weak grasp of the English language. This point is my biggest complaint because I can deal with a poorly written book so long as is readable, but this one is both poorly written AND unreadable.
Characters: So the premise of this book is summoning gods and armies to help the MC conquer a world connected to Earth. Sounds super cool with a bunch of possibilities for character interactions between the gods and mortals right? Sadly this is never presented. Characters have one or two personality traits: loyal to the MC, love the MC, one trait from their god persona (like the god Ares and Hercules likes battles or Hermes likes to run free and do mischief). Besides that, everyone is a cardboard cutout with no real depth to their character. We never even see any interactions between the gods unless the MC is present. This story would have been so much better if we could see how the gods feel about each other, how would Zeus feel about interacting with another King of Gods like Jupiter or Odin, and would they share stories or rivalries? Last on this topic, the MC is super bland. He is replaceable with anyone for he has no personality or real goals besides conquering the world. All of the work in ruling his kingdom is mainly done by his summons and he rarely does anything besides fight. Never we see him do diplomacy or bargaining with others, or make any strategy that involves anything more than just "we rush them," "we surprise attack them," or "surrender or die." Even his name is bland and uninteresting, the OP, super-duper powerful Sky Emperor... "Jerry."
World-Building: There is none. That's it.
There's nothing that makes this world interesting to read besides the premise that people can travel between earth and this cultivation world after they are 18 years old. There are no descriptions of this new world besides it being similar to an ancient earth and kingdoms are constantly at war with each other. No description of how people live, the interactions of kingdoms, notable geographic locations, or even interesting locals. But that is understandable considering how this story blazes through all of the worlds to constantly introduce new land/world to once again ignore. We never see how the day-to-day of the citizens, or how the gods and summons manage this land on behalf of the MC.
Because of how fast the story flows, we never get attached to characters when they get introduced. The closest we got was this side character the MC helps release from being a slave to a different kingdom but he quickly disappears and stops being important. The author loves throwing bigger, stronger, and larger things into the world but never expands on this. At this point in the story, the MC rules land the equivalent of 100s of Earths and that's not the biggest in the world yet.
Another point that I notice, is how everything comes so easy for the MC. Facing an enemy? summons a god. Weak against an enemy stronger than the MC? roll the system roulette and "luckily" pull the god/army/weapon needed to win. And that's the most annoying thing, even the system is redundant because it always brings exactly what the MC needs to overcome a "challenge." The system should be changed to "Authors A$$-Pull device" because it feels so forced when the author writes how the MC just happens to always get the best/needed thing to win.
So again, a novel with many flaws. They could be simply ignored and read it as a simple power fantasy with not much thought to take into it because we all like our simple power fantasies from time to time. However, the translation quality makes this story unbearable to read and when you have to not only read an unreadable story but also a story that's written badly, then nothing can save that story from a bad review.
