Review Detail of Empyrium in Eternal Thief

So nice story, I like the idea and the story, but I dont know about the grammar, it is something between normal and mtl level. The author after hundreds of chapters still has no clue how time works, he does so many mistakes, its absurd. Sometimes he use present and simple past in one sentence, the future and simple past in one sentence, some chapters, I cant really read them because they are so many mistakes! Author get a proof reader, use some apps to help you or some AI idk, just get better
