Review Detail of Nafis3642 in I'm the King Of Technology

This novel kingdom building time is too fast. The author use too much explanation when not needed but too little when needed. Plus too many wrong information. Like Muslim vs byzantine empire in chapter 379 . 200 Muslim ship's won against 500 byzantine ships . But the author said that byzantine won by a huge mergin. Plus author doesn't know about real world technology. People have automatic door but not a camera? Author also doesn't know how king's work.
