Review Detail of Amatsu in Unfortunate Hero's Retirement Life

I am sorry that i need to give such a low evaluation. I tried to read it, but my head srarted hurting while reading the first two chapter. I read novels for entertainment and to build a world in my mind while reading these stories. if i want to immerse myself into the story, it needs to have a basic level of grammar and story telling quality. I also read comments about this grammar problem and that it gets better with the chapter as the story develops. But i needed to stop reading, because my head could not take it. If possible could you please rewrite the beginning, so that it reflects the real quality of the world you build. I would really appreciate it and hope your stories get traction and your writing improves by leaps and bounds
