Here is my review about this novel:Worldbuilding; The worldbuilding is so far quite alright, especially with the system and its the mechanic that is quite interesting. Overall, its fine and has a potential to be explore more.Characters: Frank Gunn is indeed one of the most entertaining main characters with his sarcastic remark and his eagerness to fight the monsters. Furthermore, his relationship with his daughter is a strong point in this story as the author quite showed their closed bond with each others. As for other sides characters, so far they alright for now.Plot: I like the author show quite a lot of fast pace action to make it book more engaging to read. I also like the plot for the story is also quite smooth too.Overall, if you like system novel, I recommend to read this book.
